Description

  The present invention relates to a heat source device such as an air conditioner, a heat pump water heater, and a refrigerator.

  In the conventional heat source machine, vibration transmitted from the compressor to the heat exchanger via the four-way valve and the refrigerant pipe has been a problem. The heat exchanger includes a plurality of fins arranged side by side at intervals, a side plate for reinforcement arranged at at least one end of the fin group, and a plurality of heat transfer tubes penetrating the plurality of fins and the side plate. And. The side plate has higher rigidity than the fins, and the side plate is fixed to a panel member such as a partition plate or a decorative panel that partitions the inside of the heat source machine body, so if the side plate vibrates due to vibration from the compressor, There is a problem in that vibration is transmitted to the panel member to generate a radiated sound.

  Therefore, among the heat transfer tubes, the inner diameter of the through hole of the side plate through which the heat transfer tube connected to the compressor via the refrigerant pipe (hereinafter referred to as the heat transfer tube for external connection) passes is set as the outer diameter of the heat transfer tube for external connection. There is a technique in which the side plate and the external connection heat transfer tube are not in contact with each other (see, for example, Patent Document 1). In Patent Document 1, the heat transfer tube for external connection does not contact the side plate, so that the vibration of the compressor is not transmitted to the side plate, and the vibration of the side plate is reduced.

JP 2008-185268 A (page 3, lines 10 to 11, FIG. 6)

  In Patent Document 1, since the external connection heat transfer tube does not contact the side plate, the external connection heat transfer tube is held by the fins. For this reason, although the vibration of the side plate itself can be reduced, the vibration from the compressor is directly transmitted to the fins. As a result, the heat transfer tube for external connection vibrates in the heat exchanger, and the contact between the fins and the heat transfer tube is deteriorated due to the vibration. It was.

  For this reason, although it is preferable to make it the structure which hold | maintains the heat transfer tube for external connection with a side plate, in this case, the problem of the radiation sound from a panel member cannot still be solved.

  By the way, when fixing a side plate to a panel member, it is common to perform by the bending part which bent both ends of the side plate to the fin side. In addition to functioning as a fixing surface to the panel member, the bent portion also has a function of increasing the reinforcing strength of the side plate itself. However, when this bent portion is directly fixed to the panel member, there is a problem that the panel member vibrates greatly due to the vibration behavior of the side plate, and the radiated sound increases.

  The present invention has been made in order to solve the above-described problems, and has improved the fixing structure between the side plate and the panel member while maintaining the heat transfer tube for external connection with the side plate. It aims at providing the heat source machine which can reduce the radiation sound from a panel member.

  A heat source apparatus according to the present invention includes a compressor, a heat exchanger connected to the compressor by refrigerant piping, and a panel member positioned around the heat exchanger, and the heat exchangers are arranged in parallel at intervals. A plurality of strip-shaped fins and a side plate of the fin group arranged on one side of the fin group or on one side of the refrigerant pipe connected to the compressor, and a plurality of fins and side plates that are stiffer than the fins And a plurality of heat transfer tubes that are connected to the refrigerant pipe to form a refrigerant flow path, and the side plate is bent at least one end in the short direction to the fin side or the anti-fin side. It has a bending part and parts other than a bending part are fastened by the panel member via the fastening member.

  The heat source apparatus according to the present invention includes a compressor, a heat exchanger connected to the compressor by refrigerant piping, and a panel member positioned around the heat exchanger, and the heat exchanger is spaced apart. A plurality of strip-shaped fins arranged side by side and a side of the fin group or a refrigerant pipe connected to the compressor on one side, a strip-shaped side plate having rigidity higher than the fins, a plurality of fins and A plurality of heat transfer tubes that are held through the side plate and connected to the refrigerant pipe to form a refrigerant flow path, and the side plate has at least one end in the short direction on the fin side or the anti-fin side. The bent part has a bent part, and the bent part is divided into a plurality of parts at the base of the bent part into a short part and a long part in the longitudinal direction, a reinforcing part is formed at the long part, and a fastening part at the short part Formed Cage, in which the fastening portion is fastened to the panel member.

  According to the present invention, since the side plate is fixed to the panel member via the fastening member at a portion other than the bending portion for reinforcement provided at both ends in the short direction of the side plate of the heat exchanger, the panel member Radiated sound can be reduced.

  Further, according to the present invention, the bent portion of the side plate is divided into a plurality of portions at the base of the bent portion into a short portion and a long portion in the longitudinal direction, and a fastening portion is formed on the short portion side, thereby shortening. Since the fastening portion for reducing vibration is fastened to the panel member, the sound emitted from the panel member can be reduced.

Embodiment 1 FIG.
FIG. 1 is a schematic perspective view showing the heat source apparatus according to Embodiment 1 of the present invention with some components omitted. In addition, in FIG. 1, the state which removed the front plate and the top plate of the heat-source equipment 1 is shown. In FIG. 1 and each figure to be described later, the same reference numerals denote the same or equivalent parts, which are common throughout the entire specification. Furthermore, the forms of the constituent elements appearing in the entire specification are merely examples and are not limited to these descriptions.

  The heat source machine 1 has a box-shaped main body 1a, the inside of the main body 1a is partitioned into a heat exchanger chamber 3 and a machine chamber 4 by a separator 2, and the heat exchanger chamber 3 includes a heat exchanger 5 and a fan ( (Not shown) and a compressor 6 and the like are installed in the machine room 4. The heat exchanger 5 is screwed to the decorative panel 7 constituting the separator 2 and the main body 1a. The heat exchanger 5 is connected to the compressor 6 through a refrigerant pipe, but the illustration thereof is omitted in FIG. The heat source device 1 includes a type provided with a four-way valve (not shown). When the heat source device 1 is provided with the four-way valve, the heat exchanger 5 is connected to the compressor 6 through the refrigerant pipe and the four-way valve. Will be.

FIG. 2 is a schematic perspective view of the heat exchanger of FIG. FIG. 3 is a perspective view of the main part of the heat source machine according to Embodiment 1 of the present invention.
The heat exchanger 5 includes a plurality of strip-shaped fins 10 arranged in parallel at intervals, a strip-shaped side plate 11 that is disposed on both sides of the fin group, and has higher rigidity than the fins 10, and a plurality of fins 10. And a plurality of heat transfer tubes 12 which are held through the side plate 11 and connected to the refrigerant pipe to form a refrigerant flow path.

  The fin 10 is generally composed of a thin plate member made of a material such as aluminum having good heat conduction. The plurality of heat transfer tubes 12 are made of, for example, copper or the like, and reciprocate the plurality of fins 10 many times so as to change the flow direction of the refrigerant by 180 degrees with hairpins or bends protruding outward from the side plate 11. Arranged so as to penetrate.

  Since the fin 10 is a thin plate, when the heat transfer tube 12 of the heat exchanger 5 is held only by the fin 10, the shape of the fin 10 is broken when an external force is applied to the heat transfer tube 12. For this reason, a side plate 11 made of, for example, a steel plate having higher rigidity than the fin 10 is provided, and the heat transfer tube 12 is held by the side plate 11.

FIG. 4 is a perspective view of the heat exchanger of FIG. 1 viewed from the side plate side. FIG. 5 is a perspective view of the side plate of FIG.
The side plate 11 has a through hole 11a through which the heat transfer tube 12 passes, and the heat transfer tube 12 is fixed to the through hole 11a. Further, the side plate 11 has a bent portion 14 in which both ends in the short direction are bent toward the fin 10, and the bent portion 14 functions as a strength member for increasing the rigidity of the side plate 11. In the first embodiment, the bent portion 14 is referred to as a reinforcing portion 14, and the portion of the side plate 11 where the heat transfer tube 12 is fixed is referred to as a fixing portion 15.

  As shown in FIG. 3, the side plate 11 configured in this way is fixed to the separator 2 and the decorative panel 7 positioned around the side plate 11 via the fastening member 20. Details of the fixing structure will be described again. In the following, when it is not necessary to distinguish between the separator 2 and the decorative panel 7, both are collectively referred to as a panel member 13.

  The fin 10 and the side plate 11 and the heat transfer tube 12 are fixed by passing the heat transfer tube 12 through the through hole of the fin 10 and the through hole 11a of the fixing portion 15 of the side plate 11, and applying pressure from the inside of the heat transfer tube 12. Thus, the diameter of the heat transfer tube 12 is expanded and fixed by pressure. If there is a gap between the through hole 11a of the fin 10 and the heat transfer tube 12, the contact thermal resistance between the fin 10 and the heat transfer tube 12 increases and the heat transfer capability decreases. This prevents gaps from occurring.

  In the following, among the heat transfer tubes 12, as shown in FIG. 2, the heat transfer tubes 12 connected to the compressor 6 by a refrigerant pipe (not shown) and flowing in or out of the refrigerant from the compressor 6 are used for external connection. The heat transfer tube 12A is referred to as the other heat transfer tube 12 and is referred to as the heat transfer tube 12B.

  In the heat exchanger 5 configured as described above, when the refrigerant from the compressor 6 flows into the heat transfer tube 12B via the external connection heat transfer tube 12A, heat is transferred from the heat transfer tube 12B to the fins 10 and the fan ( It is a mechanism for exchanging heat with air by blowing air between the fins 10 (not shown). In addition, since the heat exchanger 5 may be used as an evaporator or a condenser when switching between cooling and heating of an air conditioner, the direction in which the refrigerant flows in the heat transfer tube 12 changes.

  Next, the vibration of the side plate 11 will be described. The vibration is transmitted from the compressor 6 to the side plate 11 via the heat transfer tube 12 as described above, and the vibration transmitted to the side plate 11 is amplified by the bending resonance of the side plate 11, and the following FIG. The behavior is as shown in.

FIG. 6 is an explanatory diagram showing the vibration of the side plate.
In the side plate 11, the fixing portion 15 vibrates in the normal direction due to vibration from the external connection heat transfer tube 12 </ b> A. The vibration displacement of the vibration B increases as the length D (see FIG. 5) of the reinforcing portion 14 of the side plate 11 increases, and accordingly, the vibration displacement of the reinforcing portion 14 also increases.

  In the conventional structure in which the reinforcing portion 14 of the side plate 11 is fixed to the panel member 13, as shown in FIG. 7, screw holes 141 are provided in the reinforcing portion 140 of the side plate 110, and the reinforcing portion 140 is directly screwed to the panel member. doing. Since the vibration C is in the normal direction to the panel member, if the reinforcing portion 140 and the panel member are firmly metal-fixed using screw fastening or welding, the large vibration of the reinforcing portion 140 remains as it is in the panel. It is transmitted to the member 130. In addition, since the panel member itself generally has a large area, when the vibration of the panel member increases, the radiated sound due to the vibration also increases.

  In consideration of the cause of the generation of the radiated sound of the panel member 13 in the first embodiment, the fixing structure between the side plate 11 and the panel member 13 is the following structure.

FIG. 8 is an enlarged cross-sectional view of the main part of the heat source machine according to Embodiment 1 of the present invention, and is a cross-sectional view taken along plane A in FIG.
In the first embodiment, the fixing portion 15 of the side plate 11 is fixed to the panel member 13 via the fastening member 20. The fastening member 20 is formed, for example, by bending a steel plate, and includes a fixing portion 21 that is fixed to the side plate 11 and a fastening portion 22 that is screwed to the panel member 13. Are formed in a substantially L-shaped cross section. A through hole 21a through which the heat transfer tube 12B passes is formed in the fixing portion 21, and the heat transfer tube 12B is passed through the through hole 21a in the same manner as the side plate 11 and the fin 10, and the fastening member 20 is expanded by increasing the diameter of the heat transfer tube 12B. The fixing portion 21, the heat transfer tube 12 </ b> B, and the side plate 11 are pressed and fixed. These fixing methods are not limited to this method, and may be fixed by brazing or the like.

  On the other hand, a screw hole 22a is formed in the fastening portion 22, and the fastening portion 22 and the panel member 13 are screw-fastened by screwing the screw 16 into the through hole 13a provided in the panel member 13 and screwing into the screw hole 22a. Has been. With the above configuration, the side plate 11 is fixed to the panel member 13 by the fastening member 20.

  Of the heat transfer tubes 12 constituting the heat exchanger 5, the external connection heat transfer tubes 12A are more susceptible to external vibration than the other heat transfer tubes 12B as described above. Therefore, in this Embodiment 1, the fixing | fixed part 21 of the fastening member 20 is fixed to the heat exchanger tube 12B side which is hard to receive a vibration. Thereby, the vibration reduction effect can be enhanced. In addition, although this invention does not necessarily limit the fixing location of the fastening member 20 to the heat exchanger tube 12B side, it is desirable to make it the heat exchanger tube 12B side from said reason.

  In the heat source device 1 configured as described above, vibration from the compressor 6 is transmitted to the side plate 11 through the heat transfer tube 12A during operation. The side plate 11 is a fastening member provided separately from the side plate 11. Since the fixing portion 15 side is fixed to the panel member 13 via 20, the vibration transmitted to the panel member 13 can be reduced compared to a structure in which the panel member 13 is screwed directly to the reinforcing portion 14 of the side plate 11, and the panel Radiated sound from the member 13 can be reduced.

  Further, in Embodiment 1, the fastening member 20 is fixed to the heat transfer tube 12B that is not connected to the outside of the heat transfer tubes 12 constituting the heat exchanger 5, so that the vibration reduction effect and the radiation noise reduction are achieved. The effect can be further enhanced.

  Further, in the first embodiment, as shown in FIGS. 4 and 8, the surface 22 b of the fastening portion 22 of the fastening member 20 protrudes outward from the surface 14 </ b> A of the reinforcing portion 14 of the side plate 11. A gap 17 is formed between the panel member 13 fastened to the fastening portion 22 and the reinforcing portion 14 of the side plate 11. Thus, by forming the gap 17 so that the panel member 13 and the reinforcing portion 14 of the side plate 11 do not contact each other, the vibration reduction effect and the radiation noise reduction effect can be further enhanced.

  Further, as shown in FIG. 9, if the cushioning material 18 is sandwiched between the gaps 17, the vibration reduction effect and the radiation noise reduction effect can be further enhanced. As the buffer material 18, a vibration damping material made of urethane, rubber, or the like, a foaming sponge, or the like can be used.

In the first embodiment, the side plates 11 are installed on both sides of the fin group, but it goes without saying that the same effect can be obtained even if only one side with the external connection heat transfer tube 12A is provided.
Further, although the side plate 11 is bent to the fin 10 side, it is needless to say that the same effect can be obtained even when the side plate 11 is bent to the opposite fin side.

Embodiment 2. FIG.
In the first embodiment, the side plate 11 is fixed to the panel member 13 via the fastening member 20 that is separate from the side plate 11. In the second embodiment, the side plate 11 itself is directly fixed to the panel member 13 while the radiation noise of the panel member 13 is reduced.

  In the second embodiment, the structure of the bent portion 14 of the side plate 11 is different from that of the first embodiment, and hereinafter, the second embodiment will be described focusing on the portions different from the first embodiment.

FIG. 10 is a perspective view showing the main part of the heat source machine according to Embodiment 2 of the present invention. FIG. 11 is a perspective view of the heat exchanger of FIG. 10 viewed from the side plate side. FIG. 12 is a plan view of FIG.
In the first embodiment, the entire bent portion 14 of the side plate 11 is a strength member. On the other hand, in the second embodiment, the bent portion 14 of the side plate 11 is divided into a plurality of portions in the longitudinal direction, and is divided into a reinforcing portion 14a used as a strength member and a fastening portion 14b used as a fastening member 20. . Specifically, it is divided by forming a notch 31 that extends from an end portion extending in the longitudinal direction (vertical direction in FIG. 10) of the bent portion 14 to the root of the bent portion 14, and the length in the longitudinal direction is long. The part is a reinforcing part 14a and the short part is a fastening part 14b.

  Since the fastening portion 14b is a part of the bent portion 14, vibration in the normal direction is generated as in the reinforcing portion 14a. However, since the length is shorter than that of the reinforcing portion 14a, vibration is smaller than that of the reinforcing portion 14a. Further, since the fastening portion 14b is separated from the reinforcing portion 14a at the base of the bent portion 14, the structure is such that the vibration of the reinforcing portion 14a is hardly transmitted to the fastening portion 14b as much as possible.

  In the bent portion 14, the fastening portion 14b and the reinforcing portion 14a have different bending angles. As shown in FIG. 12, the reinforcing portion 14a side is bent at about 90 °, whereas the fastening portion 14b side is It is bent at a smaller bending angle. The screws 16 are passed through the through holes provided in the panel member 13 and screwed into the screw holes 14c of the fastening portion 14b, whereby the fastening portion 14b and the panel member 13 are screwed. As described above, the bending angle of the fastening portion 14b is made smaller than that of the reinforcing portion 14a, and the surface positions of the fastening portion 14b and the reinforcing portion 14a are made different from each other, so that the panel member fixed to the fastening portion 14b side. 13 does not contact the reinforcing portion 14a. For this reason, it can suppress that the vibration of the reinforcement part 14a transmits to the panel member 13. FIG.

  During operation of the heat source unit 1 having the above structure, the side plate 11 of the heat exchanger 5 vibrates due to the vibration of the compressor 6 and the bent portion 14 vibrates. The vibration of the fastening portion 14b is smaller than that on the reinforcing portion 14a side. Therefore, the vibration and radiated sound of the panel member 13 can be made small.

  As described above, according to the second embodiment, the bent portion 14 of the side plate 11 of the heat exchanger 5 is divided at the base to form the reinforcing portion 14a and the fastening portion 14b, and the fastening portion 14b is formed. It was set as the structure shorter in the longitudinal direction of the bending part 14 than the reinforcement part 14a. Thereby, the vibration of the fastening portion 14b can be reduced as compared with the reinforcing portion 14a, and the fastening portion 14b with reduced vibration is screwed to the panel member 13, so that the vibration transmitted from the compressor 6 to the panel member 13 can be reduced. It is possible to reduce the radiated sound from the panel member 13.

  Further, in the second embodiment, the bending angle of the fastening portion 14b is made different from that of the reinforcing portion 14a so that the positions thereof are different from each other, and the panel member 13 is in contact with the reinforcing portion 14a having greater vibration than the fastening portion 14b. Therefore, the vibration of the reinforcing portion 14a is not directly transmitted to the panel member 13. Therefore, the vibration of the panel member 13 can be further reduced, and the radiated sound from the panel member 13 can be reduced.

  Moreover, in this Embodiment 2, since the fastening member 20 of Embodiment 1 is unnecessary and the fastening part 14b can be comprised simply by forming the notch 31 which reaches the root in the bending part 14, a manufacturing process is carried out. It can be simplified and contributes to cost reduction.

  In addition, it is preferable to provide the fastening part 14b in the position far from the heat transfer pipe 12A for external connection used as the inflow piping or outflow piping in which the force from the compressor 6 is transmitted. Although the number of the fastening portions 14b is three here, it goes without saying that the rigidity of the side plate 11 is increased if the length of the reinforcing portion 14a is increased by reducing the number of the fastening portions 14b.

Embodiment 3 FIG.
The third embodiment is basically the same as the second embodiment, and is a simplified method of dividing the reinforcing portion 14a and the fastening portion 14b in the bent portion 14 of the side plate 11. In the following, the third embodiment will be described focusing on the differences from the second embodiment.

FIG. 13: is a perspective view which shows the principal part of the heat source machine by Embodiment 3 of this invention.
In the second embodiment, a notch 31 reaching substantially the base is provided in the bent portion 14 of the side plate 11 of the heat exchanger 5 so that the bent portion 14 is divided into a reinforcing portion 14a and a fastening portion 14b. On the other hand, in the third embodiment, the bent portion 14 is simply provided with a cut that reaches substantially the base, and is divided into the reinforcing portion 14a and the fastening portion 14b.

  The plan view of the main part of the third embodiment shown in FIG. 13 is the same as that of FIG. 12 of the second embodiment. In the bent part 14, the bending angles of the fastening part 14b and the reinforcing part 14a are different from each other, and the fastening part 14b. The panel member 13 fixed to is not in contact with the reinforcing portion 14a.

  With this configuration, the same operational effects as those of the second embodiment can be obtained, and the fastening portion 14b can be easily formed in the bent portion 14 as compared with the second embodiment.
