Description
본 발명은 방열부재 일체형 열전소자유닛에 관한 것으로서, 더욱 상세하게는 열전소자하우징, 냉전도판, 열전소자, 열전도판 및 방열부재를 포함하되, 열전달파이프와 방열핀으로 구성되어 열전달파이프 하부가 열전달판 일측에 일체로 브레이징을 통해 고정됨으로써 냉수탱크의 수조커버 등에 밀착설치되는 열전소자유닛에 있어서의 방열부재에 대한 열전소자와 밀착된 상태로 설치고정이 브레이징을 통해 간편하게 이루어져 열전소자유닛의 조립작업성을 향상시킴과 동시에 생산성을 극대화시킬 수 있도록 하는 한편, 열전달파이프의 상부가 관통 고정되는 방열핀이 다수의 핀이 상하로 일정간격을 가지고 배치되어 양단에 고정판이 밀착구비되는 구조로 형성됨으로써 방열핀의 핀 사이공간을 통한 통풍이 가능하여 종래에 핀들의 일측이 밀폐되던 것과 달리 외부공기와의 접촉면적이 극대화되도록 하여 열전소자의 방열효율을 극대화시킬 수 있도록 한 방열부재 일체형 열전소자유닛에 관한 것이다.The present invention relates to a thermoelectric element unit integrated with a heat dissipation member, and more specifically, to a thermoelectric element housing, a cold-conducting plate, a thermoelectric element, a heat-conducting plate, and a heat dissipation member, including a heat transfer pipe and a heat dissipation fin, in which the lower part of the heat transfer pipe is integrally fixed to one side of the heat transfer plate through brazing, so that the thermoelectric element in the thermoelectric element unit, which is installed in close contact with the water tank cover of a cold water tank, is easily installed and fixed through brazing, thereby improving the assembling workability of the thermoelectric element unit and maximizing productivity. In addition, since the upper part of the heat transfer pipe is fixed through and through a heat dissipation fin, a plurality of fins are arranged at regular intervals vertically and fixing plates are closely installed at both ends, ventilation is possible through the space between the fins of the heat dissipation fins, so that, unlike the conventional case where one side of the fins is sealed, the contact area with the outside air is maximized, thereby maximizing the heat dissipation efficiency of the thermoelectric element. This relates to a thermoelectric device unit integrated with a heat dissipation member that can be used.
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 8에 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. 8, comprises a water tank body (111) having an inlet for introducing water from the outside and an outlet for discharging cooled water, a water tank cover (112) for covering an opening of the water tank body, a cold sink (130) attached to an outer surface of the water tank cover for transmitting cold air to the inside of the water 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.
특히, 상기와 같은 냉수탱크에 적용되는 열전소자를 포함하는 열전소자유닛의 설치구조에서의 방열부재인 히트싱크(150)는 판 상의 열전달부 일면에 다수의 방열핀이 구비된 구조로 적용되어 별도의 결합수단으로 열전소자(120)와 밀착되게 설치고정해야 하므로 방열부재의 설치과정이 복잡하다는 문제가 있었다.In particular, in the installation structure of a thermoelectric element unit including a thermoelectric element applied to a cold water tank as described above, the heat sink (150), which is a heat dissipation member, is applied in a structure in which a number of heat dissipation fins are provided on one surface of a plate-shaped heat transfer section, and must be installed and fixed in close contact with the thermoelectric element (120) by a separate connecting means, so there was a problem in that the installation process of the heat dissipation member was complicated.
아울러, 방열부재의 설치과정이 복잡함에 따라 열전소자유닛의 조립작업성이 저하됨과 동시에 생산성을 저하시키는 문제가 있었다.In addition, there was a problem that the assembly workability of the thermoelectric element unit was reduced and productivity was reduced as the installation process of the heat dissipation member was complicated.
더욱이, 방열부재로 적용되는 히트싱크(150)가 판 상의 열전달부 일면에 다수의 방열핀이 구비된 구조로 적용됨으로써 판 상의 열전달부에 의해 열전소자의 발열측에 대한 송풍팬(160)의 공기 및 외부공기와의 접촉이 차단되어 방열효율이 떨어지는 문제가 있었다.Furthermore, since the heat sink (150) applied as a heat dissipation member is applied with a structure in which a number of heat dissipation fins are provided on one surface of the heat transfer portion on the plate, there was a problem in that the heat dissipation efficiency was reduced because the contact between the air of the blower fan (160) and the outside air on the heat-generating side of the thermoelectric element was blocked by the heat transfer portion on the plate.
그러므로 냉수탱크의 수조커버 등에 밀착설치되는 열전소자유닛에 있어서, 방열부재의 열전소자와 밀착된 상태로 설치고정이 간편하게 이루어져 열전소자유닛의 조립작업성을 향상시킴과 동시에 생산성을 극대화시킬 수 있도록 하는 한편, 방열부재에 대해 외부공기와의 접촉면적이 극대화되도록 하여 열전소자의 방열효율을 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 be easily installed and fixed in a close contact state with a thermoelectric element of a heat-radiating member, thereby improving the assembly workability of the thermoelectric element unit and maximizing productivity, while also maximizing the contact area between the heat-radiating member and the outside air, thereby maximizing the heat dissipation efficiency of the thermoelectric element.
상기와 같은 문제점을 해결하기 위하여, 본 발명은 열전소자하우징, 냉전도판, 열전소자, 열전도판 및 방열부재를 포함하되, 열전달파이프와 방열핀으로 구성되어 열전달파이프 하부가 열전달판 일측에 일체로 브레이징을 통해 고정됨으로써 냉수탱크의 수조커버 등에 밀착설치되는 열전소자유닛에 있어서의 방열부재에 대한 열전소자와 밀착된 상태로 설치고정이 브레이징을 통해 간편하게 이루어져 열전소자유닛의 조립작업성을 향상시킴과 동시에 생산성을 극대화시킬 수 있도록 한 방열부재 일체형 열전소자유닛을 제공하는 것을 목적으로 한다.In order to solve the above problems, the present invention provides a thermoelectric element unit including a thermoelectric element housing, a cold-conducting plate, a thermoelectric element, a heat-conducting plate, and a heat-radiating member, wherein the lower part of the heat transfer pipe is integrally fixed to one side of the heat transfer plate by brazing, so that the thermoelectric element in the thermoelectric element unit, which is installed in close contact with the heat-radiating member of the water tank cover of a cold water tank, can be easily installed and fixed by brazing, thereby improving the assembly workability of the thermoelectric element unit and maximizing productivity.
본 발명에 따른 기술의 다른 목적은 열전소자하우징, 냉전도판, 열전소자, 열전도판 및 방열부재를 포함하되, 열전달파이프의 상부가 관통 고정되는 방열핀이 다수의 핀이 상하로 일정간격을 가지고 배치되어 양단에 고정판이 밀착구비되는 구조로 형성됨으로써 방열핀의 핀 사이공간을 통한 통풍이 가능하여 종래에 핀들의 일측이 밀폐되던 것과 달리 외부공기와의 접촉면적이 극대화되도록 하여 열전소자의 방열효율을 극대화시킬 수 있도록 함에 있다.Another object of the technology according to the present invention is to provide a thermoelectric element housing, a cold conductive plate, a thermoelectric element, a heat conductive plate, and a heat dissipation member, wherein a plurality of heat dissipation fins are formed in a structure in which the upper part of a heat transfer pipe is penetrated and fixed, and a plurality of fins are arranged at regular intervals vertically and fixed plates are closely attached at both ends, thereby enabling ventilation through the space between the fins of the heat dissipation fins, thereby maximizing the contact area with the outside air, unlike in the past where one side of the fins was sealed, thereby maximizing the heat dissipation efficiency of the thermoelectric element.
전술한 목적을 달성하기 위한 본 발명은 다음과 같다. 즉, 본 발명에 따른 방열부재 일체형 열전소자유닛는 냉각대상물 일 측에 밀착설치되어 냉각대상물 측으로부터 흡열하여 외부로 방출하면서 냉각대상물을 냉각시키는 열전소자유닛에 있어서, 장방형의 틀 형상으로 제공되어 내부공간 후단 양측에 내향 구속리브가 돌출되고, 전면 둘레의 사방에 원기둥 형상으로 돌출되어 고정돌부가 형성되며, 전면 둘레부분을 따라 연이어 접착수단이 충전되는 충전홈이 함몰형성되는 열전소자하우징; 열전소자하우징의 전방부로부터 삽입안착되되, 전방부의 폭 방향 양측에 외향 단이 지게 돌출된 걸림단부 후면이 열전소자하우징의 구속리브와의 사이에 탄성스프링이 개재되어 밀착되며, 후면이 열전소자하우징으로부터 외부로 노출되어 냉각대상물과 밀착배치되는 냉전도판; 열전소자하우징 내부에 삽입설치되되, 흡열 측인 후면이 냉전도판의 전면과 밀착되어 냉각대상물 측으로 냉기가 전달되도록 하는 열전소자; 열전소자하우징의 고정돌부가 삽입고정되는 고정공이 사방 모서리 부분에 관통형성되고, 전면에 다수의 고정홈이 함몰 형성되며, 후면이 열전소자의 발열 측인 전면에 밀착되어 접착수단을 통해 냉전도판, 열전소자와 하나의 조립체를 이루는 열전도판; 및 하부가 열전도판의 고정홈에 밀착고정되어, 열전도판과 열교환하면서 열전도판의 열을 외부로 방열시키는 방열부재;를 포함하는 구성으로 이루어진다.In order to achieve the above-mentioned object, the present invention is as follows. That is, the thermoelectric element unit integrated with a heat dissipation member according to the present invention is a thermoelectric element unit that 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 to cool the cooling object, the thermoelectric element housing being provided in a rectangular frame shape so that inwardly directed restraining ribs protrude on both sides of the rear end of the internal space, and having fixing protrusions formed in a cylindrical shape on all sides of the front periphery, and having a filling groove formed in a sunken shape in which an adhesive means is continuously filled along the front periphery; a cold conductive plate that is inserted and settled from the front part of the thermoelectric element housing, and has an elastic spring interposed between the rear part of the engaging end portion that protrudes outwardly on both sides in the width direction of the front part and the restraining rib of the thermoelectric element housing so as to be in close contact with it, the rear part being exposed to the outside from the thermoelectric element housing and being placed in close contact with the cooling object; The present invention comprises: a thermoelectric element which is inserted and installed inside a thermoelectric element housing, the rear surface which is the heat-absorbing side being in close contact with the front surface of a cold-conducting plate so that cold air is transferred to the cooling target side; a heat-conducting plate which has fixing holes formed through all four corners, into which fixing projections of the thermoelectric element housing are inserted and fixed, a plurality of fixing grooves formed sunken in the front surface, and the rear surface being in close contact with the front surface which is the heat-generating side of the thermoelectric element, thereby forming a single assembly with the cold-conducting plate and the thermoelectric element through an adhesive means; and a heat-radiating member which is in close contact with the fixing grooves of the heat-conducting plate at the lower portion, and radiates heat of the heat-conducting plate to the outside while exchanging heat with the heat-conducting plate.
이때, 상기 방열부재는 하부 일정길이에 걸쳐 열전도판의 고정홈에 밀착설치되며, 상향 일정길이 연장되어 내부에 열전도판과 열교환하여 외부로 방열시키기 위한 냉각유체가 충전되는 방열파이프 및 방열파이프의 열전도판의 고정홈과 밀착설치된 상부가 관통고정되며, 방열파이프의 내부에 충전된 냉각유체가 열전도판의 열과 열교환하여 상승한 상태에서 외부공기와 접촉을 통해 방열되도록 하는 방열핀을 포함하는 것이 바람직하다.At this time, it is preferable that the heat dissipation member is installed in close contact with the fixing groove of the heat-conducting plate over a certain length at the bottom, and includes a heat dissipation pipe that is extended upward a certain length and filled with a cooling fluid for heat exchange with the heat-conducting plate inside and heat dissipation to the outside, and a heat dissipation fin that is installed in close contact with the fixing groove of the heat-conducting plate of the heat dissipation pipe and penetrates and is fixed, and allows the cooling fluid filled inside the heat dissipation pipe to heat-exchange with the heat of the heat-conducting plate and rise, thereby radiating heat through contact with the outside air.
더욱이, 상기 방열핀은 일정두께의 판 형상으로 제공되는 다수의 핀이 상하로 일정간격을 가지고 배치되며, 다수의 핀 양단에는 고정판이 밀착구비되는 것이 양호하다.Furthermore, it is preferable that the heat dissipation fins are provided in the form of plates of a certain thickness and are arranged vertically at a certain interval, and that fixing plates are closely attached to both ends of the fins.

도 1 내지 7에서 보는 바와 같이, 본 발명의 바람직한 실시예에 따른 방열부재 일체형 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), 열전도판(140) 및 방열부재(150)를 포함하여 이루어진다.As shown in FIGS. 1 to 7, a thermoelectric element unit (100) integrated with a heat dissipation member according to a preferred embodiment of the present invention is installed in close contact with one side of a cooling object (10) and cools the cooling object (10) by absorbing heat from the cooling object (10) and releasing it to the outside. It is broadly classified to include a thermoelectric element housing (110), a cold-conducting plate (120), a thermoelectric element (130), a heat-conducting plate (140), and a heat dissipation member (150).
이때, 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.At this time, the cooling target (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 the open opening of the water tank body (11) is tightly sealed by the water tank cover (15).
이하, 본 발명의 바람직한 실시예에 따른 방열부재 일체형 열전소자유닛(100)의 세부구성에 대해 설명하면, 먼저 상기 열전소자하우징(110)은 장방형의 틀 형상으로 제공되어 내부공간 후단 양측에 내향 구속리브(111)가 돌출되며, 전면 둘레의 사방에 원기둥 형상으로 돌출되어 고정돌부(113)가 형성된다.Hereinafter, a detailed configuration of a thermoelectric element unit (100) integrated with a heat dissipation member according to a preferred embodiment of the present invention will be described. First, the thermoelectric element housing (110) is provided in a rectangular frame shape, with inwardly directed restraining ribs (111) protruding on both sides of the rear end of the internal space, and a fixed projection (113) protruding in a cylindrical shape on all four sides of the front periphery.
아울러, 상기와 같은 열전소자하우징(110)은 전면 둘레부분을 따라 연이어 접착수단이 충전되는 충전홈(115)이 함몰형성된다.In addition, the thermoelectric element housing (110) as described above has a recessed filling groove (115) formed along the front periphery into which an adhesive means is continuously filled.
한편, 상기 냉전도판(120)은 열전소자하우징(110)의 전방부로부터 삽입안착되되, 전방부의 폭 방향 양측에 외향 단이 지게 돌출된 걸림단부(121) 후면이 열전소자하우징(110)의 구속리브(111)와의 사이에 탄성스프링(S)이 개재되어 밀착되는 것이다.Meanwhile, the cold plate (120) is inserted and fixed from the front of the thermoelectric element housing (110), and the rear of the engaging end (121) protruding outwardly on both sides in the width direction of the front is brought into close contact with the restraining rib (111) of the thermoelectric element housing (110) by interposing an elastic spring (S).
이러한 냉전도판(120)은 특히, 후면이 열전소자하우징(110)으로부터 외부로 노출되어 냉각대상물(10)의 수조커버(15) 중앙부분과 밀착배치되는 것이다This cold-conducting plate (120) is particularly positioned so that the rear surface is exposed to the outside from the thermoelectric element housing (110) and is in close contact with the central part 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).
상기와 같은 열전소자(130)는 통상의 열전소자와 마찬가지로 2개의 전선이 연결되며, 이때 전선은 열전소자하우징(110)에 열전소자(130)의 전선을 제외한 본체부분이 삽입설치된 상태에서 열전소자하우징(110)의 전선설치홈(미부호)을 통해 외부로 인출된 상태가 유지되는 것이 바람직하다.The thermoelectric element (130) as described above is connected to two wires, just like a typical thermoelectric element. At this time, it is preferable that the wires be maintained in a state where the main body part of the thermoelectric element (130) excluding the wires is inserted and installed in the thermoelectric element housing (110) and are pulled out to the outside through the wire installation groove (not shown) of the thermoelectric element housing (110).
그리고 상기 열전도판(140)은 열전소자하우징(110)의 고정돌부(113)가 삽입고정되는 고정공(141)이 사방 모서리 부분에 관통형성되며, 전면에 다수의 고정홈(143)이 함몰 형성된다.And the heat-conducting plate (140) has a fixing hole (141) formed through the four corners into which the fixing projection (113) of the thermoelectric element housing (110) is inserted and fixed, and a number of fixing grooves (143) are formed sunken in the front surface.
이와 같은 열전도판(140)은 후면이 열전소자(130)의 발열 측인 전면에 밀착되어 접착수단을 통해 냉전도판(120), 열전소자(130)와 하나의 조립체를 이루는 것이 바람직하다.It is preferable that the heat-conducting plate (140) of this type be attached to the front side, which is the heating side of the thermoelectric element (130), with the rear side thereof to form a single assembly with the cold-conducting plate (120) and the thermoelectric element (130) through an adhesive means.
또한, 상기 방열부재(150)는 하부가 열전도판(140)의 고정홈(143)에 밀착고정되어, 열전도판(140)과 열교환하면서 열전도판(140)의 열을 외부로 방열시키는 것이다.In addition, the lower part of the heat dissipation member (150) is tightly fixed to the fixing groove (143) of the heat conducting plate (140), thereby exchanging heat with the heat conducting plate (140) and dissipating the heat of the heat conducting plate (140) to the outside.
이러한 방열부재(150)는 크게 방열파이프(151) 및 방열핀(155)으로 구성된다.This heat dissipation member (150) is largely composed of a heat dissipation pipe (151) and a heat dissipation fin (155).
상세히, 상기 방열파이프(151)는 하부 일정길이에 걸쳐 열전도판(140)의 고정홈(143)에 밀착설치되며, 상향 일정길이 연장되어 내부에 열전도판(140)과 열교환하여 외부로 방열시키기 위한 냉각유체가 충전되는 것이다.In detail, the above heat dissipation pipe (151) is installed in close contact with the fixing groove (143) of the heat conducting plate (140) over a certain length of the lower portion, and is extended upward a certain length so that a cooling fluid is filled therein to exchange heat with the heat conducting plate (140) and radiate heat to the outside.
이때, 상기 냉각유체는 냉매로 제공됨이 바람직하다.At this time, it is preferable that the cooling fluid be provided as a refrigerant.
다시 말해서, 상기 방열파이프(151)는 내부에 냉매가 충전된 상, 하단이 밀폐처리된 중공의 원기둥 타입으로 제공될 수 있는 것이다.In other words, the above-mentioned heat dissipation pipe (151) can be provided as a hollow cylindrical type with the upper and lower parts sealed and filled with refrigerant inside.
이러한 방열파이프(151)는 특히, 열전도 및 열교환 효율이 높은 동(銅) 재질의 파이프로 적용됨이 바람직한 것이다.It is particularly preferable that these heat dissipation pipes (151) be made of copper material with high heat conductivity and heat exchange efficiency.
그리고 상기 방열핀(155)은 방열파이프(151)의 열전도판(140)의 고정홈(143)과 밀착설치된 상부가 관통고정되며, 방열파이프(151)의 내부에 충전된 냉각유체가 열전도판(140)의 열과 열교환하여 상승한 상태에서 외부공기와 접촉을 통해 방열되도록 하는 것이다.And the above-mentioned heat dissipation fin (155) is installed in close contact with the fixing groove (143) of the heat conduction plate (140) of the heat dissipation pipe (151) and is fixed through penetration, so that the cooling fluid filled inside the heat dissipation pipe (151) is heat-exchanged with the heat of the heat conduction plate (140) and then rises and radiates heat through contact with the outside air.
이때, 상기 방열핀(155)은 일정두께의 판 형상으로 제공되는 다수의 핀(155a)이 상하로 일정간격을 가지고 배치되며, 다수의 핀(155a) 양단에는 고정판(155b)이 밀착구비되는 것이 바람직하다.At this time, the heat dissipation fins (155) are preferably provided in the form of plates of a certain thickness, with a plurality of fins (155a) arranged at a certain interval in the upper and lower directions, and a fixing plate (155b) is preferably installed in close contact at both ends of the plurality of fins (155a).
다시 말해서, 일정간격을 가지고 다수 개로 배치되는 방열핀(155a)의 사이들을 통해 외부공기가 통풍되면서 접촉될 수 있는 것이다.In other words, external air can be ventilated and brought into contact through the gaps between the heat dissipation fins (155a) arranged in a number of pieces at regular intervals.
또한, 상기 방열파이프(151)는 하부 일정길이에 걸쳐 열전도판(140)의 고정홈(143)에 밀착된 상태로 브레이징을 통해 고정되며, 상단으로부터 하향 일정길이에 걸쳐 방열핀(155)을 관통하는 상태에서 브레이징을 통해 방열핀(155)과 고정되는 것이 바람직한 것이다.In addition, it is preferable that the heat dissipation pipe (151) be fixed by brazing while in close contact with the fixing groove (143) of the heat conducting plate (140) over a certain length at the bottom, and be fixed to the heat dissipation fin (155) by brazing while penetrating the heat dissipation fin (155) over a certain length downward from the top.
더욱이, 방열핀(155)을 관통하는 상태는 도면에 도시된 바와 같이, 핀(155a)의 길이방향으로 다수 개로 관통된 관통공(미부호)을 통해 관통함이 바람직하다.Furthermore, it is preferable that the state of penetrating the heat dissipation fin (155) be through a plurality of through holes (not shown) that are penetrated in the longitudinal direction of the fin (155a), as shown in the drawing.
상기와 같은 관통공(미부호)은 특히, 방열파이프(151)의 외경과 동일하거나 긴 길이를 갖는 지름을 가지는 원형 홀로 제공되되, 일 측에 신축을 위한 확장홈이 더 확장형성되어 확장홈 구조를 통해 관통공(미부호)의 내경이 벌어졌다 오므라들게 신축되면서 방열파이프(151)의 관통 삽입이 원활하게 이루어짐이 더욱 바람직한 것이다.The above-described through hole (not shown) is particularly provided as a circular hole having a diameter equal to or longer than the outer diameter of the heat dissipation pipe (151), but it is more preferable that an expansion groove for expansion be further formed on one side so that the inner diameter of the through hole (not shown) expands and contracts through the expansion groove structure, thereby allowing smooth penetration insertion of the heat dissipation pipe (151).
한편, 전술한 바와 같은 구성으로 이루어진 본 발명에 따른 방열부재 일체형 열전소자유닛(100)은 방열파이프(151) 하부에 대해 열전도판(140)의 전면 측에 브레이징을 통한 고정이 용이하도록, 상기 열전도판(140)의 고정홈(143)은 반구 형상으로 함몰 형성됨이 바람직하다.Meanwhile, in order to facilitate fixing of the heat conduction plate (140) to the front side of the lower portion of the heat dissipation pipe (151) through brazing, it is preferable that the fixing groove (143) of the heat conduction plate (140) of the heat dissipation member-integrated thermoelectric element unit (100) according to the present invention, which is configured as described above, be formed in a hemispherical shape.
아울러, 상기 방열파이프(151)는 상, 하단이 밀폐처리되는 중공의 원기둥 타입 관체로 제공되는 것이 바람직한 것이다.In addition, it is preferable that the heat dissipation pipe (151) be provided as a hollow cylindrical tube with the upper and lower parts sealed.

이를 위하여, 열전소자하우징(110) 내에 냉전도판(120)과 열전소자(130)를 삽입시킨 후에 접착수단으로서 에폭시를 충전한 후 열전소자하우징(110)의 열전소자(130) 측을 열전도판(140)이 덮히도록 한 상태에서, 가열, 냉각하는 과정을 통해, 열전소자하우징(110), 냉전도판(120), 열전소자(130) 및 열전도판(140)이 하나의 조립체를 이루도록 제작될 수 있다.To this end, after inserting a cold conductive plate (120) and a thermoelectric element (130) into a thermoelectric element housing (110), filling epoxy as an adhesive, and then covering the thermoelectric element (130) side of the thermoelectric element housing (110) with a heat conductive plate (140), the thermoelectric element housing (110), the cold conductive plate (120), the thermoelectric element (130), and the heat conductive plate (140) can be manufactured to form a single assembly through a heating and cooling process.
더욱이, 상기 열전소자하우징(110)은 전면 둘레부분을 따라 연이어 함몰형성되는 충전홈(115) 내에 접착수단으로서 에폭시가 충전되어, 전면 둘레부분에 대해 열전도판(140)의 후면 둘레부분과 긴밀하게 접착고정되는 것이 바람직한 것이다.Furthermore, it is preferable that the thermoelectric element housing (110) is filled with epoxy as an adhesive in the filling groove (115) that is continuously formed along the front peripheral portion, so that the front peripheral portion is closely bonded and fixed to the rear peripheral portion of the heat-conducting plate (140).
이때, 에폭시는 일정온도 및 일정시간의 조건으로 가열하여 열전소자하우징(110)과 열전도판(140)이 상호 접착되게 함이 바람직하다.At this time, it is preferable to heat the epoxy under conditions of a certain temperature and a certain period of time so that the thermoelectric element housing (110) and the heat conducting plate (140) are mutually adhered.
전술한 바와 같은 구성으로 이루어진 본 발명에 따른 방열부재 일체형 열전소자유닛(100)은 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 heat dissipation member-integrated thermoelectric element unit (100) 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 therewith, 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.
