Description
본 발명은 이중 씰링구조를 갖는 열전소자유닛에 관한 것으로서, 더욱 상세하게는 열전소자하우징, 냉전도판, 열전소자, 열전도판을 포함하되, 냉전도판의 둘레부분과 열전소자하우징의 걸림단턱 사이에 내부씰링부재가 개재되면서 열전소자하우징과 열전도판의 마주하는 둘레부분 사이에 외부씰링부재가 개재됨으로써 냉수탱크의 수조커버 등에 밀착설치되는 열전소자유닛에 있어서의 에폭시 등의 접착수단을 대신하는 별도의 간단한 설치구조를 통한 2중의 씰링부재 구조를 구현할 수 있으며, 이에 따라 제조시간을 단축함과 동시에 제조공정을 단순화함으로써 생산성을 극대화시킬 수 있도록 한 이중 씰링구조를 갖는 열전소자유닛에 관한 것이다.The present invention relates to a thermoelectric element unit having a double sealing structure, and more specifically, to a thermoelectric element unit including a thermoelectric element housing, a cold-conducting plate, a thermoelectric element, and a heat-conducting plate, wherein an internal sealing member is interposed between the peripheral portion of the cold-conducting plate and a catch tab of the thermoelectric element housing, and an external sealing member is interposed between the facing peripheral portions of the thermoelectric element housing and the heat-conducting plate, thereby realizing a double sealing member structure through a separate simple installation structure instead of an adhesive means such as epoxy in a thermoelectric element unit that is closely installed on a water tank cover of a cold water tank, and thereby maximizing productivity by shortening the manufacturing time and simplifying the manufacturing process.
일반적으로 열전소자는 냉매를 순환시키기 위해 압축기를 가동시키는 기존의 냉각방식을 탈피한 환경친화적인 냉각방식으로서, 소형이면서도 세라믹 재질로 이루어진 박판의 열전소자 양측면이 전극전환을 통해 간단하게 냉각과 방열을 동시에 수행하는 부품으로써, 그에 부착되는 블록들과 함께 유닛을 형성하여 현재 열교환 산업분야에서 널리 사용되고 있다.In general, a thermoelectric element is an environmentally friendly cooling method that breaks away from the existing cooling method of operating a compressor to circulate a refrigerant. It is a component that performs cooling and heat dissipation simultaneously by simply switching electrodes on both sides of a small, thin-plate thermoelectric element made of ceramic material, and is widely used in the current heat exchange industry by forming a unit together with the blocks attached to it.
상기와 같은 열전소자는 이미 설명한 바와 같이 전원이 공급되면 일측면이 냉각되고 이 냉각상태가 계속해서 유지될 수 있도록 반드시 타측면은 방열되는 특성이 있다.As already explained, the thermoelectric element as described above has the characteristic that when power is supplied, one side is cooled and the other side must dissipate heat so that this cool state can be maintained continuously.
따라서, 타측면의 방열이 효율적으로 진행되면 될수록 냉각면의 온도가 낮아지게 된다.Therefore, the more efficiently the heat dissipation on the other side is performed, the lower the temperature of the cooling surface becomes.
그러므로, 열전소자유닛의 냉각효율은 열전소자의 방열면에서 방열이 원활하게 이루어져 온도가 낮아지고, 이와 더불어 냉각면의 저온이 열손실없이 냉각대상물까지 그대로 전달되는 것에 의해 결정된다.Therefore, the cooling efficiency of the thermoelectric element unit is determined by the smooth heat dissipation on the heat dissipation surface of the thermoelectric element, thereby lowering the temperature, and furthermore, by the low temperature of the cooling surface being transferred to the cooled object without heat loss.
상기와 같은 열전소자는 정수기나 냉온수기 등의 주요한 구성요소로서 본체의 내부 공간으로 유입된 물을 냉각하여 시원한 물을 제공하는 장치로서의, 냉수탱크에 적용되고 있는 실정이다.The above-mentioned thermoelectric elements are used as major components in water purifiers, water coolers, etc., and are applied to cold water tanks as devices that cool water that flows into the internal space of the main body to provide cool water.
이때, 상기 냉수탱크의 구조는 도 1에 도시된 바와 같이, 외부로부터 물을 유입하기 위한 유입구와 냉각된 물을 배출하기 위한 배출구가 구비된 수조본체(111), 수조본체의 개구부를 덮기 위한 수조커버(112), 수조커버의 외면에 부착되어 냉기를 수조커버의 내부로 전달하기 위한 콜드싱크(130), 콜드싱크의 반대측에 부착된 열전소자(120), 및 열전소자의 반대측에 부착되어 방열 기능을 수행하는 히트싱크(150)를 포함하여 구성되고, 기타 송풍팬(160), 단열부재(190) 등을 더 포함할 수 있는 것이다.At this time, the structure of the cold water tank, as illustrated in FIG. 1, comprises a tank body (111) having an inlet for introducing water from the outside and an outlet for discharging cooled water, a tank cover (112) for covering an opening of the tank body, a cold sink (130) attached to an outer surface of the tank cover for transmitting cold air to the inside of the tank cover, a thermoelectric element (120) attached to the opposite side of the cold sink, and a heat sink (150) attached to the opposite side of the thermoelectric element for performing a heat dissipation function, and may further include a blower fan (160), an insulating member (190), etc.
또한, 상기와 같은 냉수탱크는 유입구와 배출구 사이에 격벽부재(170)를 부가하여 유입구 측의 온수와 배출구 측의 냉수가 서로 섞이지 않도록 구성된다.In addition, the cold water tank as described above is configured so that hot water on the inlet side and cold water on the outlet side do not mix with each other by adding a partition member (170) between the inlet and the outlet.
그런데 상기 냉수탱크는 열전소자 부착되는 콜드싱크(130)와 본체를 형성하는 수조커버(112)가 독립된 구성요소로서 서로 부착되는 부분을 열이 통과하는 과정에서 열 전달 손실이 발생하게 된다.However, in the above cold water tank, the cold sink (130) to which the thermoelectric element is attached and the water tank cover (112) forming the main body are independent components, and heat transfer loss occurs in the process of heat passing through the part where they are attached to each other.
이를 해소하기 위하여 수조커버(112)와 콜드싱크(130) 사이의 접합면에 열전도성을 증가시키기 위한 서멀 그리스(thermal grease)를 도포하기도 하지만, 여전히 두 구성요소 간의 분리면에 따른 열 전달 손실을 완전하게 해소하지 못한다.To solve this problem, thermal grease is applied to the joint surface between the tank cover (112) and the cold sink (130) to increase thermal conductivity, but the heat transfer loss due to the separation surface between the two components is still not completely resolved.
또한, 유입구와 배출구 사이의 격벽부재(170)에 의하여 냉온수가 섞이는 문제를 해소할 수 있으나, 격벽부재(170)를 별도의 구성요소로서 내부 공간의 일정한 위치에 배치하기 위하여 브라켓(140)을 구비해야 하고 브라켓을 수조본체에 고정하기 위한 고정수단 등의 부속이 필요하고, 복잡한 구성요소 간의 조립을 위한 작업 공정이 매우 번거로운 단점이 있다.In addition, the problem of mixing of hot and cold water can be solved by the partition member (170) between the inlet and outlet, but there is a disadvantage in that a bracket (140) must be provided to place the partition member (170) as a separate component at a certain position in the internal space, and accessories such as a fixing means for fixing the bracket to the tank body are required, and the work process for assembling the complex components is very cumbersome.
더욱이, 열전소자가 적용되어 냉수탱크의 수조커버에 콜드싱크가 밀착설치되는 종래의 열전소자유닛은 특허문헌 1(한국등록특허 제10-0780734호 2007.11.23.등록.)에 개시된 바와 같이, 히트싱크와 쿨블록 사이로서, 하우징의 수납실에 수납된 열전반도체소자에 대해 외부와 긴밀한 차단이 이루어질 수 있도록, 제1접착제와 제2접착제 등의 접착수단을 적용하였다.Furthermore, as disclosed in Patent Document 1 (Korean Patent No. 10-0780734, registered on November 23, 2007), a conventional thermoelectric element unit in which a thermoelectric element is applied and a cold sink is installed in close contact with a water tank cover of a cold water tank uses adhesive means such as a first adhesive and a second adhesive to ensure that a thermoelectric semiconductor element housed in a storage room of a housing can be tightly sealed from the outside between the heat sink and the cool block.
그러나 이러한 종래의 열전소자유닛(열전반도체소자 유니트)은 에폭시 등의 접착수단을 적용함에 따라 제조시간이 길어지면서 제조공정이 복잡하다는 문제가 있었다.However, these conventional thermoelectric element units (thermoelectric semiconductor element units) had the problem that the manufacturing process was complicated and the manufacturing time was long due to the application of adhesives such as epoxy.
그러므로 냉수탱크의 수조커버 등에 밀착설치되는 열전소자유닛에 있어서, 에폭시 등의 접착수단을 대신하여 별도의 간단한 씰링구조를 적용함으로써 제조시간을 단축함과 동시에 제조공정을 단순화할 수 있으며, 이를 통하여 생산성을 극대화시킬 수 있도록 한 열전소자유닛에 대해 연구 및 개발이 요구되는 실정이다.Therefore, in a thermoelectric element unit that is installed in close contact with a water tank cover of a cold water tank, research and development are required for a thermoelectric element unit that can shorten the manufacturing time and simplify the manufacturing process by applying a separate simple sealing structure instead of an adhesive such as epoxy, thereby maximizing productivity.
상기와 같은 문제점을 해결하기 위하여, 본 발명은 열전소자하우징, 냉전도판, 열전소자, 열전도판을 포함하되, 냉전도판의 둘레부분과 열전소자하우징의 걸림단턱 사이에 내부씰링부재가 개재되면서 열전소자하우징과 열전도판의 마주하는 둘레부분 사이에 외부씰링부재가 개재됨으로써 냉수탱크의 수조커버 등에 밀착설치되는 열전소자유닛에 있어서의 에폭시 등의 접착수단을 대신하는 별도의 간단한 설치구조를 통한 2중의 씰링부재 구조를 구현할 수 있도록 한 이중 씰링구조를 갖는 열전소자유닛을 제공하는 것을 목적으로 한다.In order to solve the above problems, the present invention provides a thermoelectric element unit having a double sealing structure, which comprises a thermoelectric element housing, a cold-conducting plate, a thermoelectric element, and a heat-conducting plate, wherein an internal sealing member is interposed between the peripheral portion of the cold-conducting plate and a catch tab of the thermoelectric element housing, and an external sealing member is interposed between the facing peripheral portions of the thermoelectric element housing and the heat-conducting plate, thereby enabling a double sealing member structure to be implemented through a separate simple installation structure instead of an adhesive means such as epoxy in a thermoelectric element unit that is closely installed on a water tank cover of a cold water tank, etc.
본 발명에 따른 기술의 다른 목적은 냉전도판의 둘레부분과 열전소자하우징의 걸림단턱 사이에 내부씰링부재가 개재되면서 열전소자하우징과 열전도판의 마주하는 둘레부분 사이에 외부씰링부재가 개재됨에 따라 간단한 설치구조를 통한 2중의 씰링부재 구조를 구현할 수 있도록 함으로써 제조시간을 단축함과 동시에 제조공정을 단순화할 수 있으며, 이를 통하여 열전소자유닛의 생산성을 극대화시킬 수 있도록 함에 있다.Another object of the technology according to the present invention is to enable a double sealing member structure through a simple installation structure by interposing an internal sealing member between the peripheral portion of a cold-conducting plate and a catch step of a thermoelectric element housing and an external sealing member between the facing peripheral portions of the thermoelectric element housing and the heat-conducting plate, thereby shortening the manufacturing time and simplifying the manufacturing process, thereby maximizing the productivity of the thermoelectric element unit.
전술한 목적을 달성하기 위한 본 발명은 다음과 같다. 즉, 본 발명에 따른 이중 씰링구조를 갖는 열전소자유닛은 냉각대상물 일 측에 밀착설치되어 냉각대상물 측으로부터 흡열하여 외부로 방출하면서 냉각대상물을 냉각시키는 열전소자유닛에 있어서, 장방형의 틀 형상으로 제공되어 내부공간 후단 사방으로부터 내향 중심측으로 단이 지게 구속리브가 돌출되고, 전면 둘레의 사방 모서리부분에 원기둥 형상으로 돌출되어 고정돌부가 형성되는 열전소자하우징; 열전소자하우징의 전방부로부터 삽입안착되되, 전방부의 사방으로 외향 단이 지게 걸림단부가 형성되어 걸림단부에 대해 열전소자하우징의 구속리브와 밀착되며, 후면이 열전소자하우징으로부터 외부로 노출되어 냉각대상물과 밀착배치되는 냉전도판; 열전소자하우징 내부에 삽입설치되되, 흡열 측인 후면이 냉전도판의 전면과 밀착되어 냉각대상물 측으로 냉기가 전달되도록 하는 열전소자; 및 열전소자하우징의 고정돌부가 삽입고정되는 고정공이 사방 모서리 부분에 관통형성되고, 후면이 열전소자의 발열 측인 전면에 밀착되며, 열전소자의 발열 측으로부터 전도되는 열을 외부로 방열시키는 방열부재의 후면이 밀착설치되는 열전도판;을 포함하는 한편, 열전소자하우징 내부에 냉전도판, 열전소자가 삽입설치된 후 열전소자의 전면에 열전도판 후면이 밀착배치된 상태에서 이중씰링조립수단을 통해 하나의 조립체를 이루도록 조립되는 구성으로 이루어진다.In order to achieve the above-mentioned object, the present invention is as follows. That is, a thermoelectric element unit having a double sealing structure according to the present invention is a thermoelectric element unit which is installed in close contact with one side of a cooling object and absorbs heat from the cooling object side and releases it to the outside while cooling the cooling object, the thermoelectric element housing being provided in a rectangular frame shape and having a restraining rib protruding inwardly from all four sides of the rear end of the internal space toward the center, and having a fixing projection formed in a cylindrical shape at all four corners of the front periphery; a cold conductive plate which is inserted and settled from the front part of the thermoelectric element housing, has a hooking end formed in all four sides of the front part so as to be in close contact with the restraining rib of the thermoelectric element housing against the hooking end, and has a rear surface exposed to the outside from the thermoelectric element housing so as to be in close contact with the cooling object; A thermoelectric element which is inserted and installed inside a thermoelectric element housing, and has a rear surface on the heat-absorbing side in close contact with the front surface of a cold-conducting plate so that cold air is transferred to the cooling target side; and a heat-conducting plate which has fixing holes formed through all corners of the thermoelectric element housing into which fixing projections of the thermoelectric element are inserted and fixed, has a rear surface in close contact with the front surface on the heat-generating side of the thermoelectric element, and has a rear surface of a heat-radiating member which radiates heat conducted from the heat-generating side of the thermoelectric element to the outside in close contact with the rear surface; and is configured such that after the cold-conducting plate and the thermoelectric element are inserted and installed inside the thermoelectric element housing, the rear surface of the heat-conducting plate is in close contact with the front surface of the thermoelectric element and is assembled to form a single assembly through a double sealing assembly means.
이때, 상기 이중씰링조립수단은 열전소자하우징의 전면 둘레부분을 따라 연이어 함몰형성되는 외부씰링홈에 후방이 일정깊이 삽입되어 열전도판의 밀착에 의해 열전소자하우징의 열전소자가 삽입설치되는 영역에 대해 열전소자하우징 전방측 외부와 긴밀하게 밀폐시키는 외부씰링부재와, 열전소자하우징의 구속리브 전면에 둘레방향으로 연이어 함몰형성되는 내부씰링홈에 후방이 일정깊이 삽입되어 냉전도판의 걸림단부 후면의 밀착에 의해 열전소자가 삽입설치되는 영역에 대해 열전소자하우징 후방측 외부와 긴밀하게 밀폐시키는 내부씰링부재 및 열전도판 사방을 관통하여 관통된 단부가 열전소자하우징의 전면 사방에 나사결합되면서 열전도판과 열전소자하우징의 둘레부분이 밀착된 상태로 조립고정하는 조립볼트를 포함하는 것이 바람직하다.At this time, it is preferable that the double sealing assembly means include an external sealing member whose rear end is inserted into an external sealing groove formed successively along the front periphery of the thermoelectric element housing to a certain depth so as to seal tightly the front exterior of the thermoelectric element housing with respect to the region where the thermoelectric element of the thermoelectric element housing is to be inserted and installed by the close contact of the heat conduction plate, an internal sealing member whose rear end is inserted into an internal sealing groove formed successively in the circumferential direction on the front surface of the restraining rib of the thermoelectric element housing to a certain depth so as to seal tightly the rear exterior of the thermoelectric element housing with respect to the region where the thermoelectric element is to be inserted and installed by the close contact of the rear surface of the engaging end of the cold conduction plate, and an assembly bolt which penetrates through all sides of the heat conduction plate and assembles and fixes the heat conduction plate and the periphery of the thermoelectric element housing in a state where they are in close contact while the penetrated ends are screw-connected to all sides of the front surface of the thermoelectric element housing.
더욱이, 조립볼트를 통한 열전도판과 열전소자하우징의 사방 둘레부분이 밀착된 상태로 조립고정시 열전도판과 열전소자하우징의 사방 둘레부분 전체에 걸쳐 긴밀한 밀착상태가 유지되게 조립고정될 수 있도록, 상기 열전도판은 사방에는 각 모서리부분 사이에 일정간격을 가지고 각 한 쌍의 조립공이 관통형성되는 한편, 상기 열전소자하우징은 전면 사방에 열전도판의 조립공과 대응되어, 각 모서리부분 사이에 일정간격을 가지고 한 쌍의 조립나사홈이 함몰형성되는 것이 양호하다.Furthermore, when the heat-conducting plate and the thermoelectric element housing are assembled and fixed in a close contact state with the four surrounding parts through the assembly bolts, it is preferable that the heat-conducting plate has a pair of assembly holes formed through it with a certain interval between each corner on each side, while the thermoelectric element housing has a pair of assembly screw grooves formed recessed with a certain interval between each corner on all four sides of the front surface, corresponding to the assembly holes of the heat-conducting plate.
아울러, 열전도판의 조립공을 통해 조립볼트가 조립된 후 볼트머리부에 대해 외부로 돌출되지 않도록, 상기 조립공은 전방측에 외향 확장되어 조립볼트의 볼트머리부가 삽입되는 확장삽입부를 갖는 홀로 제공되는 것이 바람직하다.In addition, in order to prevent the assembly bolt from protruding outwardly relative to the bolt head after being assembled through the assembly hole of the heat-conducting plate, it is preferable that the assembly hole be provided as a hole having an expanded insertion portion that extends outwardly on the front side and into which the bolt head of the assembly bolt is inserted.
또한, 상기 열전모듈하우징은 열전도판이 밀착되는 측으로부터 방열부재가 결합볼트를 통해 고정설치될 수 있도록, 고정돌부 내부에 너트가 인서트 사출을 통해 구비되어, 열전도판이 밀착되는 측으로부터 방열부재가 밀착된 상태로 결합볼트가 방열부재를 관통하여 관통된 나사몸체부의 단부에 대해 인서트 너트에 체결되면서 고정설치되는 것이 양호하다.In addition, it is preferable that the thermoelectric module housing is provided with a nut inserted into the fixing projection through insert injection so that the heat dissipation member can be fixedly installed through a joining bolt from the side where the heat conduction plate is in contact, so that the heat dissipation member is in contact from the side where the heat conduction plate is in contact, and the joining bolt penetrates the heat dissipation member and is fixedly installed by fastening the insert nut to the end of the screw body portion that has penetrated the heat dissipation member.
본 발명에 따른 이중 씰링구조를 갖는 열전소자유닛의 효과를 설명하면 다음과 같다.The effects of the thermoelectric element unit having a double sealing structure according to the present invention are as follows.
첫째, 열전소자하우징, 냉전도판, 열전소자, 열전도판을 포함하되, 냉전도판의 둘레부분과 열전소자하우징의 걸림단턱 사이에 내부씰링부재가 개재되면서 열전소자하우징과 열전도판의 마주하는 둘레부분 사이에 외부씰링부재가 개재됨으로써 냉수탱크의 수조커버 등에 밀착설치되는 열전소자유닛에 있어서의 에폭시 등의 접착수단을 대신하는 별도의 간단한 설치구조를 통한 2중의 씰링부재 구조를 구현할 수 있다.First, a double sealing member structure can be implemented through a separate simple installation structure that replaces an adhesive means such as epoxy in a thermoelectric element unit that is installed in close contact with a water tank cover of a cold water tank, by including a thermoelectric element housing, a cold-conducting plate, a thermoelectric element, and a heat-conducting plate, but wherein an internal sealing member is interposed between the peripheral portion of the cold-conducting plate and the engaging step of the thermoelectric element housing, and an external sealing member is interposed between the facing peripheral portions of the thermoelectric element housing and the heat-conducting plate.
둘째, 냉전도판의 둘레부분과 열전소자하우징의 걸림단턱 사이에 내부씰링부재가 개재되면서 열전소자하우징과 열전도판의 마주하는 둘레부분 사이에 외부씰링부재가 개재됨에 따라 간단한 설치구조를 통한 2중의 씰링부재 구조를 구현할 수 있도록 함으로써 제조시간을 단축함과 동시에 제조공정을 단순화할 수 있으며, 이를 통하여 열전소자유닛의 생산성을 극대화시킬 수 있다.Second, since an internal sealing member is interposed between the peripheral portion of the cold-conducting plate and the engaging step of the thermoelectric element housing, and an external sealing member is interposed between the facing peripheral portions of the thermoelectric element housing and the heat-conducting plate, a double sealing member structure can be implemented through a simple installation structure, thereby shortening the manufacturing time and simplifying the manufacturing process, thereby maximizing the productivity of the thermoelectric element unit.

도 2 내지 7에서 보는 바와 같이, 본 발명의 바람직한 실시예에 따른 이중 씰링구조를 갖는 열전소자유닛(100)은 냉각대상물(10) 일 측에 밀착설치되어 냉각대상물(10) 측으로부터 흡열하여 외부로 방출하면서 냉각대상물(10)을 냉각시키는 것으로, 크게 분류하면 열전소자하우징(110), 냉전도판(120), 열전소자(130) 및 열전도판(140)을 포함하여 이루어진다.As shown in FIGS. 2 to 7, a thermoelectric element unit (100) having a double sealing structure according to a preferred embodiment of the present invention is installed in close contact with one side of a cooling object (10) to absorb heat from the cooling object (10) and release it to the outside, thereby cooling the cooling object (10). Broadly speaking, it is composed of a thermoelectric element housing (110), a cold-conducting plate (120), a thermoelectric element (130), and a heat-conducting plate (140).
상기 냉각대상물(10)은 예컨대, 냉전도판(120)이 밀착설치되어 내부에 저장된 유체를 냉각시키는 냉수탱크에서의 수조로서, 수조본체(11)의 개방된 개구부를 수조커버(15)가 긴밀하게 밀폐시키는 구성으로 적용된다.The above cooling object (10) is, for example, a water tank in a cold water tank in which a cold conductive plate (120) is installed in close contact to cool the fluid stored inside, and is applied in a configuration in which an open opening of a water tank body (11) is tightly sealed by a water tank cover (15).
이하, 본 발명의 바람직한 실시예에 따른 이중 씰링구조를 갖는 열전소자유닛(100)의 세부구성에 대해 설명하면, 상기 열전소자하우징(110)은 장방형의 틀 형상으로 제공되어 내부공간 후단 사방으로부터 내향 중심측으로 단이 지게 구속리브(111)가 돌출된다.Hereinafter, a detailed configuration of a thermoelectric element unit (100) having a double sealing structure according to a preferred embodiment of the present invention will be described. The thermoelectric element housing (110) is provided in a rectangular frame shape, and a restraining rib (111) protrudes inwardly from all four sides of the rear end of the internal space toward the center.
또한, 상기 열전소자하우징(110)은 전면 둘레의 사방 모서리부분에 원기둥 형상으로 돌출되어 고정돌부(113)가 형성된다.In addition, the thermoelectric element housing (110) is formed with a fixed projection (113) that protrudes in a cylindrical shape at the four corners of the front periphery.
상기와 같은 열전모듈하우징(110)은 특히, 열전도판(140)이 밀착되는 측으로부터 방열부재(150)가 결착볼트를 통해 고정설치될 수 있도록, 고정돌부(113) 내부에 너트(N)가 인서트 사출을 통해 구비된다.In particular, the thermoelectric module housing (110) as described above is provided with a nut (N) through insert injection inside the fixing projection (113) so that the heat dissipation member (150) can be fixedly installed through a fixing bolt from the side where the heat conducting plate (140) is in close contact.
이러한 열전모듈하우징(110)은 열전도판(140)이 밀착되는 측으로부터 방열부재(150)가 밀착된 상태로 결착볼트(미도시)가 방열부재(150)를 관통하여 관통된 나사몸체부의 단부에 대해 인서트 너트(N)에 체결되면서 고정설치되는 것이 바람직한 것이다.It is preferable that the thermoelectric module housing (110) be fixedly installed by having a fixing bolt (not shown) penetrate the heat dissipation member (150) from the side where the heat conducting plate (140) is in contact and fastened to an insert nut (N) at the end of the screw body portion that penetrates the heat dissipation member (150).
한편, 상기 냉전도판(120)은 열전소자하우징(110)의 전방부로부터 삽입안착되되, 전방부의 사방으로 외향 단이 지게 걸림단부(121)가 형성되어 걸림단부(121)에 대해 열전소자하우징(110)의 구속리브(111)와 밀착된다.Meanwhile, the cold-conducting plate (120) is inserted and fixed from the front of the thermoelectric element housing (110), and a catch end (121) is formed with an outward end facing in all directions of the front, so that the catch end (121) is in close contact with the restraining rib (111) of the thermoelectric element housing (110).
이러한 냉전도판(120)은 후면이 열전소자하우징(110)으로부터 외부로 노출되어 냉각대상물(10)의 수조커버(15) 중앙부분과 밀착배치되는 것이다.The rear surface of this cold-conducting plate (120) is exposed to the outside from the thermoelectric element housing (110) and is placed in close contact with the central portion of the water tank cover (15) of the cooling target (10).
또한, 상기 열전소자(130)는 열전소자하우징(110) 내부에 삽입설치되되, 흡열 측인 후면이 냉전도판(120)의 전면과 밀착되어 냉각대상물(10) 측으로 냉기가 전달되도록 하는 것이다.In addition, the thermoelectric element (130) is inserted and installed inside the thermoelectric element housing (110), and the rear side, which is the heat absorption side, is in close contact with the front side of the cold conductive plate (120) so that cold air is transferred to the cooling target (10).
이러한 열전소자(130)는 통상의 열전소자와 마찬가지로 2개의 전선이 연결되며, 이러한 전선은 열전소자하우징(110)에 소자본체부분이 삽입설치된 상태에서 열전소자하우징(110)의 전선설치홈(미부호)을 통해 외부로 인출된 상태가 유지되는 것이 바람직하다.These thermoelectric elements (130) are connected to two wires like a typical thermoelectric element, and it is preferable that these wires be maintained in a state where they are extended to the outside through the wire installation groove (not shown) of the thermoelectric element housing (110) while the element body part is inserted and installed in the thermoelectric element housing (110).
그리고 상기 열전도판(140)은 열전소자하우징(110)의 고정돌부(113)가 삽입고정되는 고정공(141)이 사방 모서리 부분에 관통형성된다.And the heat-conducting plate (140) has a fixing hole (141) formed through all four corners into which the fixing projection (113) of the thermoelectric element housing (110) is inserted and fixed.
이러한 열전도판(140)은 후면이 열전소자(130)의 발열 측인 전면에 밀착되며, 열전소자(130)의 발열 측으로부터 전도되는 열을 외부로 방열시키는 방열부재(150)의 후면이 밀착설치되는 것이다.The rear side of this heat-conducting plate (140) is in close contact with the front side, which is the heating side of the thermoelectric element (130), and the rear side of a heat-radiating member (150) that radiates heat conducted from the heating side of the thermoelectric element (130) to the outside is installed in close contact with it.
상기와 같은 열전도판(140)은 도면으로 구체적으로 도시하지는 않았으나, 열전소자하우징(110) 내에 냉전도판(120), 열전소자(130)가 삽입설치된 후 열전소자하우징(110)과 조립볼트(B)를 통해 조립된 상태에서, 방열부재(150)의 밀착설치시 별도의 결착볼트(미도시)를 열전도판(140)의 사방 모서리부분에 관통된 고정공(141)을 관통하여 열전소자하우징(110)의 고정돌부(113) 내에 내설된 인서트 너트(N)에 체결된다.The above-described heat-conducting plate (140) is not specifically illustrated in the drawing, but after the cold-conducting plate (120) and the thermoelectric element (130) are inserted and installed in the thermoelectric element housing (110), the thermoelectric element housing (110) is assembled with the assembly bolt (B), and when the heat-radiating member (150) is tightly installed, a separate fastening bolt (not illustrated) is fastened to the insert nut (N) installed in the fixing projection (113) of the thermoelectric element housing (110) by passing through the fixing hole (141) that penetrates the four corners of the heat-conducting plate (140).
상기와 같은 과정을 통해 열전도판(140)의 전면 측으로부터 방열부재(150)가 밀착된 상태로 고정설치될 수 있으며, 물론 상기 방열부재(150)는 브레이징이나 접착제 등을 통해 밀착설치될 수도 있는 것이다.Through the above process, the heat dissipation member (150) can be installed in a close contact state from the front side of the heat conducting plate (140), and of course, the heat dissipation member (150) can also be installed in close contact through brazing or adhesive, etc.
다시 말해서, 도면으로 구체적으로 도시하지는 않았으나, 상기 열전모듈하우징(110)은 열전도판(140)이 밀착되는 측으로부터 방열부재(150)가 결착볼트(미도시)를 통해 고정설치될 수 있도록, 고정돌부(113) 내부에 너트(N)가 인서트 사출을 통해 구비된다.In other words, although not specifically shown in the drawing, the thermoelectric module housing (110) is provided with a nut (N) through insert injection inside the fixing projection (113) so that the heat dissipation member (150) can be fixedly installed through a fixing bolt (not shown) from the side where the heat conducting plate (140) is in contact.
즉, 상기 열전모듈하우징(110)은 열전도판(140)이 밀착되는 측으로부터 방열부재(150)이 밀착된 상태로 인서트 너트(N)에 결착볼트(미도시)의 나사몸체부가 체결되면서 고정설치될 수 있는 것이다.That is, the above-mentioned thermoelectric module housing (110) can be fixedly installed by fastening the screw body of the fixing bolt (not shown) to the insert nut (N) while the heat dissipation member (150) is in contact with the side where the heat conducting plate (140) is in contact.
전술한 바와 같은 구성으로 이루어진 본 발명에 따른 이중 씰링구조를 갖는 열전소자유닛(100)은 특히, 열전소자하우징(110) 내부에 냉전도판(120), 열전소자(130)가 삽입설치된 후 열전소자(130)의 전면에 열전도판(140) 후면이 밀착배치된 상태에서 이중씰링조립수단을 통해 하나의 조립체를 이루도록 조립되는 것이다.The thermoelectric element unit (100) having a double sealing structure according to the present invention, which is configured as described above, is assembled to form a single assembly by means of a double sealing assembly means, in particular, after a cold conductive plate (120) and a thermoelectric element (130) are inserted and installed inside a thermoelectric element housing (110), the rear side of the thermal conductive plate (140) is placed in close contact with the front side of the thermoelectric element (130).
이때, 상기 이중씰링조립수단은 외부씰링부재(110S)와, 내부씰링부재(120S) 및 조립볼트(B)를 포함한다.At this time, the double sealing assembly means includes an external sealing member (110S), an internal sealing member (120S), and an assembly bolt (B).
상세히, 상기 외부씰링부재(110S)는 열전소자하우징(110)의 전면 둘레부분을 따라 연이어 함몰형성되는 외부씰링홈(115)에 후방이 일정깊이 삽입되어 열전도판(140)의 밀착에 의해 열전소자하우징(110)의 열전소자(130)가 삽입설치되는 영역에 대해 열전소자하우징(110) 전방측 외부와 긴밀하게 밀폐시키는 것이다.In detail, the external sealing member (110S) is inserted to a certain depth at the rear into an external sealing groove (115) that is continuously formed along the front periphery of the thermoelectric element housing (110) so that the area where the thermoelectric element (130) of the thermoelectric element housing (110) is inserted is tightly sealed with the front exterior of the thermoelectric element housing (110) by the adhesion of the heat conducting plate (140).
또한, 상기 내부씰링부재(120S)는 열전소자하우징(110)의 구속리브(111) 전면에 둘레방향으로 연이어 함몰형성되는 내부씰링홈(117)에 후방이 일정깊이 삽입되어 냉전도판(120)의 걸림단부(121) 후면의 밀착에 의해 열전소자(130)가 삽입설치되는 영역에 대해 열전소자하우징(110) 후방측 외부와 긴밀하게 밀폐시키는 것이다.In addition, the inner sealing member (120S) is inserted to a certain depth at the rear into an inner sealing groove (117) that is formed continuously in the circumferential direction on the front of the restraining rib (111) of the thermoelectric element housing (110), so that the area where the thermoelectric element (130) is inserted and installed is tightly sealed with the outside of the rear side of the thermoelectric element housing (110) by contact with the rear of the engaging end (121) of the cold conductive plate (120).
그리고 상기 조립볼트(B)는 열전도판(140) 사방을 관통하여 관통된 단부가 열전소자하우징(110)의 전면 사방에 나사결합되면서 열전도판(140)과 열전소자하우징(110)의 둘레부분이 밀착된 상태로 조립고정하는 것이다.And the above assembly bolt (B) penetrates the heat conducting plate (140) on all sides and the penetrated end is screwed onto the front all sides of the thermoelectric element housing (110), thereby assembling and fixing the heat conducting plate (140) and the peripheral portion of the thermoelectric element housing (110) in a state of close contact.
전술한 바와 같은 구성들로 이루어진 이중씰링조립수단은 조립볼트(B)를 통한 열전도판(140)과 열전소자하우징(110)의 사방 둘레부분이 밀착된 상태로 조립고정시 열전도판(140)과 열전소자하우징(110)의 사방 둘레부분 전체에 걸쳐 긴밀한 밀착상태가 유지되게 조립고정될 수 있도록 하는 것이 중요하다.It is important that the double sealing assembly means, which is composed of the configurations described above, be assembled and fixed in a state where the heat conducting plate (140) and the thermoelectric element housing (110) are in close contact with each other on all sides through the assembly bolts (B) so that the heat conducting plate (140) and the thermoelectric element housing (110) are in close contact with each other on all sides.
이를 위하여, 상기 열전도판(140)은 사방에는 각 모서리부분 사이에 일정간격을 가지고 각 한 쌍의 조립공(145)이 관통형성되는 것이 바람직하다.To this end, it is preferable that the heat-conducting plate (140) has a pair of assembly holes (145) formed through each of the four corners with a certain interval between them.
아울러, 상기 열전소자하우징(110)은 전면 사방에 열전도판(140)의 조립공(145)과 대응되어, 각 모서리부분 사이에 일정간격을 가지고 한 쌍의 조립나사홈(119)이 함몰형성되는 것이 바람직한 것이다.In addition, it is preferable that the thermoelectric element housing (110) is formed with a pair of assembly screw grooves (119) sunken in at a certain interval between each corner portion, corresponding to the assembly holes (145) of the heat-conducting plate (140) on all four sides of the front surface.
더욱이, 상기 열전도판(140)의 조립공(145)을 통해 조립볼트(B)가 조립된 후 볼트머리부에 대해 외부로 돌출되지 않도록 하는 것이 중요하며, 이를 위하여 상기 조립공(145)은 전방측에 외향 확장되어 조립볼트(B)의 볼트머리부가 삽입되는 확장삽입부를 갖는 홀로 제공되는 것이 바람직하다.Furthermore, it is important to prevent the assembly bolt (B) from protruding outwardly from the bolt head after being assembled through the assembly hole (145) of the heat-conducting plate (140), and to this end, it is preferable that the assembly hole (145) be provided as a hole having an expansion insertion portion that extends outwardly on the front side and into which the bolt head of the assembly bolt (B) is inserted.
예컨대, 상기 조립볼트(B)는 접시머리 타입의 볼트로 제공될 수 있으며, 이러한 경우 상기 조립공(145)은 조립볼트(B)의 나사몸체부 전방측에 외향 접시머리 타입과 대응되어 테이퍼지게 확장되는 확장삽입부(미부호)로 제공된다.For example, the assembly bolt (B) may be provided as a countersunk head type bolt, in which case the assembly hole (145) is provided as an expansion insertion portion (not shown) that is tapered and expanded to correspond to the outwardly facing countersunk head type on the front side of the screw body of the assembly bolt (B).
물론, 상기 조립볼트(B)는 둥근머리 타입의 볼트로 제공될 수 있으며, 이러한 경우 상기 조립공(145)은 조립볼트(B)의 나사몸체부 전방측에 외향 둥근머리 타입과 대응되어 단이 지게 확장되는 확장삽입부(미도시)로 제공되는 것이다.Of course, the above assembly bolt (B) may be provided as a round head type bolt, and in this case, the assembly hole (145) is provided as an expansion insertion part (not shown) that is extended to correspond to the outwardly facing round head type on the front side of the screw body of the assembly bolt (B).
전술한 바와 같은 구성으로 이루어진 본 발명에 따른 이중 씰링구조를 갖는 열전소자유닛(100)은 냉전도판(120)의 후면부분에 대해 냉각대상물(10)의 수조커버(15)에 밀착설치시에 접착수단, 예컨대 본드 등의 접착제 또는 브레이징 등을 통해 접착될 수 있으며, 다른 한편으로는 볼트와 결합나사홈 등의 결합고정수단을 통해 결착될 수 있는 것이다.The thermoelectric element unit (100) having a double sealing structure according to the present invention, which is configured as described above, can be attached to the water tank cover (15) of the cooling target (10) by means of an adhesive, such as a bond, or brazing, when installed in close contact with the rear surface of the cold conductive plate (120), and on the other hand, can be fastened by means of a fastening means, such as a bolt or a screw groove.
상기와 같은 접착수단 및 결합고정수단 등은 통상의 열전소자유닛에서의 냉각대상물과의 밀착설치시에 적용되는 수단과 대등한 것으로, 이하 상세한 설명은 생략하기로 한다.The above-mentioned adhesive means and bonding and fixing means are equivalent to the means used when installing a cooling target in a conventional thermoelectric element unit, and a detailed description thereof will be omitted below.
전술한 바와 같은 구성으로 이루어진 본 발명에 따른 이중 씰링구조를 갖는 열전소자유닛에 의하면, 열전소자하우징, 냉전도판, 열전소자, 열전도판을 포함하되, 냉전도판의 둘레부분과 열전소자하우징의 걸림단턱 사이에 내부씰링부재가 개재되면서 열전소자하우징과 열전도판의 마주하는 둘레부분 사이에 외부씰링부재가 개재됨으로써 냉수탱크의 수조커버 등에 밀착설치되는 열전소자유닛에 있어서의 에폭시 등의 접착수단을 대신하는 별도의 간단한 설치구조를 통한 2중의 씰링부재 구조를 구현할 수 있다.According to the thermoelectric element unit having a double sealing structure according to the present invention, which is configured as described above, the thermoelectric element unit includes a thermoelectric element housing, a cold-conducting plate, a thermoelectric element, and a heat-conducting plate, wherein an internal sealing member is interposed between the peripheral portion of the cold-conducting plate and the engaging step of the thermoelectric element housing, and an external sealing member is interposed between the facing peripheral portions of the thermoelectric element housing and the heat-conducting plate, thereby implementing a double sealing member structure through a separate simple installation structure that replaces an adhesive means such as epoxy in a thermoelectric element unit that is installed in close contact with a water tank cover of a cold water tank, etc.
더욱이, 냉전도판의 둘레부분과 열전소자하우징의 걸림단턱 사이에 내부씰링부재가 개재되면서 열전소자하우징과 열전도판의 마주하는 둘레부분 사이에 외부씰링부재가 개재됨에 따라 간단한 설치구조를 통한 2중의 씰링부재 구조를 구현할 수 있도록 함으로써 제조시간을 단축함과 동시에 제조공정을 단순화할 수 있으며, 이를 통하여 열전소자유닛의 생산성을 극대화시킬 수 있게 된다.Furthermore, since an internal sealing member is interposed between the peripheral portion of the cold-conducting plate and the engaging step of the thermoelectric element housing, and an external sealing member is interposed between the facing peripheral portions of the thermoelectric element housing and the heat-conducting plate, a double sealing member structure can be implemented through a simple installation structure, thereby shortening the manufacturing time and simplifying the manufacturing process, thereby maximizing the productivity of the thermoelectric element unit.
