Description

Technical Field

[0001] The present invention relates to the field of household electrical appliances, and more specifically, to a heat dissipation component, a heat pump system and an air conditioner. Background Art

[0002] In existing air conditioners, if the temperature of the control module is too high, it will trigger a self-protection mechanism of frequency reduction, causing the system's cooling capacity to decrease. At present, the heat dissipation methods for the control module on the market mainly include aluminum fin radiator heat dissipation and U-shaped refrigerant ring heat dissipation (refrigerant ring heat dissipation is to connect the refrigerant ring in series with the air conditioner's heat pump system, and the refrigerant passing through the refrigerant ring absorbs the heat of the control module to achieve cooling of the control module). Compared with aluminum fin radiator heat dissipation, refrigerant ring heat dissipation has a stronger heat dissipation capacity.

[0003] However, since the refrigerant ring is installed on the control module (i.e., the control board), in order to prevent the control module from short-circuiting due to condensation caused by low local temperature, the temperature of the refrigerant ring needs to be slightly higher than the outdoor temperature, which also restricts the heat dissipation efficiency and effect of the control module. How to better improve the heat dissipation efficiency and effect of the control module is a technical problem that technicians in this field need to solve urgently. Summary of the invention

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0032] The air conditioner provided in the embodiment of the present invention is as follows: Figures 1 to 4 As shown, a heat pump system is included, and the heat pump system includes a heat dissipation component 100, a heat pump flow path and a control module. Figure 4 As shown, the heat dissipation assembly 100 includes: a heat pipe module 110, the heat pipe module 110 includes an evaporation section 111 and a condensation section 112, and the control module is arranged in the evaporation section 111; and a refrigerant heat exchanger 120, the refrigerant heat exchanger 120 is arranged in the condensation section 112, and the heat pump flow path includes the refrigerant heat exchanger 120.

[0033] The air conditioner has a control module disposed in the evaporation section 111, and a heat pump flow path includes a refrigerant heat exchanger 120. When the air conditioner performs cooling operation, the temperature of the control module is higher than the temperature of the evaporation section 111, and the working medium in the evaporation section 111 changes from a liquid state to a gaseous state to absorb the heat emitted by the control module, thereby cooling the control module. Then, the gaseous working medium in the evaporation section 111 flows to the condensation section 112. Since the temperature of the evaporation section 111 is always not lower than the ambient temperature, the control module will not generate condensed water and cause a short circuit. The working medium in the condensation section 112 changes from a gaseous state to a liquid state to release heat, and then the liquid working medium in the condensation section 112 The working fluid flows to the evaporation section 111, and the temperature of the refrigerant in the refrigerant heat exchanger 120 is lower than the temperature of the condensation section 112. The refrigerant in the refrigerant heat exchanger 120 absorbs the heat released by the working fluid in the condensation section 112. The temperature of the refrigerant in the refrigerant heat exchanger 120 can be set to be lower than the ambient temperature. In this way, the refrigerant in the refrigerant heat exchanger 120 can absorb the heat released by the working fluid in the condensation section 112 more quickly and efficiently, thereby achieving the purpose of improving the heat dissipation efficiency and heat dissipation effect of the control module. Although condensation water may be generated in the condensation section 112, this part of condensation water is not located on the control module and will not cause a short circuit in the control module.

[0034] The heat pipe module 110 is a mature technology. The heat pipe module 110 also includes an insulation section and a liquid wick structure. The insulation section is located between the evaporation section 111 and the condensation section 112, and the liquid wick structure is located inside the evaporation section 111, the insulation section and the condensation section 112. When the air conditioner is in cooling operation, the temperature of the control module is higher than the temperature of the evaporation section 111, and the working fluid in the heat pipe module 110 changes from liquid to gas to absorb the heat emitted by the control module, thereby cooling the control module. Then, the gaseous working fluid in the evaporation section 111 flows to the condensation section 112 through the insulation section. Since the temperature of the evaporation section 111 is always not lower than the ambient temperature, the control module will not produce condensed water and short-circuit; the working fluid in the condensation section 112 changes from gas to liquid to release heat, and then the liquid working fluid in the condensation section 112 flows to the evaporation section 111 through the liquid wick structure. The temperature of the refrigerant in the refrigerant heat exchanger 120 is lower than the temperature of the condensing section 112. The refrigerant in the refrigerant heat exchanger 120 absorbs the heat released by the working fluid in the condensing section 112. The temperature of the refrigerant in the refrigerant heat exchanger 120 can be set to be lower than the ambient temperature. In this way, the refrigerant in the refrigerant heat exchanger 120 can absorb the heat released by the working fluid in the condensing section 112 more quickly and efficiently, thereby achieving the purpose of improving the heat dissipation efficiency and heat dissipation effect of the control module. Although condensed water may be generated in the condensing section 112, this part of condensed water is not located on the control module and will not cause a short circuit in the control module.

[0035] In some examples, such as Figure 1 and Figure 4As shown, the heat pump system also includes an outdoor heat exchanger 310, a first throttle valve 320, an indoor heat exchanger 330, a compressor 340 and a four-way valve 350. One end of the indoor heat exchanger 330, the first throttle valve 320, the refrigerant heat exchanger 120 and one end of the outdoor heat exchanger 310 are connected in sequence, and the other end of the indoor heat exchanger 330, the other end of the outdoor heat exchanger 310 and the compressor 340 are connected through the four-way valve 350. The outdoor heat exchanger 310, the refrigerant heat exchanger 120, the first throttle valve 320, the indoor heat exchanger 330, the four-way valve 350 and the compressor 340 construct a heat pump flow path. In this scheme, in the cooling mode, the temperature of the refrigerant in the refrigerant heat exchanger 120 is higher than the ambient temperature but lower than the temperature of the condensing section. It can be that the first throttle valve 320 is an electronic expansion valve or a capillary tube.

[0036] In other examples, such as Figure 2 and Figure 4 As shown, the heat pump system also includes an outdoor heat exchanger 310, a first throttle valve 320, an indoor heat exchanger 330, a compressor 340 and a four-way valve 350. One end of the indoor heat exchanger 330, the refrigerant heat exchanger 120, the first throttle valve 320 and one end of the outdoor heat exchanger 310 are connected in sequence, and the other end of the indoor heat exchanger 330, the other end of the outdoor heat exchanger 310 and the compressor 340 are connected through the four-way valve 350. The outdoor heat exchanger 310, the first throttle valve 320, the refrigerant heat exchanger 120, the indoor heat exchanger 330, the four-way valve 350 and the compressor 340 construct a heat pump flow path. In this scheme, in the cooling mode, the temperature of the refrigerant in the refrigerant heat exchanger 120 is lower than the ambient temperature, and the heat dissipation efficiency and heat dissipation effect of the control module are better. It can be that the first throttle valve 320 is an electronic expansion valve or a capillary tube.

[0037] In some other examples, such as Figure 3 and Figure 4As shown, the heat pump system also includes an outdoor heat exchanger 310, a first throttle valve 320, a second throttle valve 360, an indoor heat exchanger 330, a compressor 340 and a four-way valve 350. One end of the indoor heat exchanger 330, the first throttle valve 320, the refrigerant heat exchange element 120, the second throttle valve 360 ​​and one end of the outdoor heat exchanger 310 are connected in sequence, and the other end of the indoor heat exchanger 330, the other end of the outdoor heat exchanger 310 and the compressor 340 are connected through the four-way valve 350. The outdoor heat exchanger 310, the second throttle valve 360, the refrigerant heat exchange element 120, the first throttle valve 320, the indoor heat exchanger 330, the four-way valve 350 and the compressor 340 construct a heat pump flow path. In this solution, in the cooling mode, the opening of the first throttle valve 320 is smaller than the opening of the second throttle valve 360. The opening of the second throttle valve 360 ​​can be adjusted to not more than the set opening, so that the temperature of the refrigerant in the refrigerant heat exchanger 120 is lower than the ambient temperature, so that the heat dissipation efficiency and heat dissipation effect of the control module are better. At this time, although condensation water may be generated in the condensing section 112 and the refrigerant heat exchanger 120, this part of the condensation water will not flow to the control module, and will not cause the control module to short-circuit. In the heating mode, the opening of the first throttle valve 320 is adjusted to the maximum. The heat pump system can realize the function of quick dissolving of thin frost.

[0038] The light frost quick melting function can solve the problems of large temperature fluctuation, valve group noise and abnormal sound caused by thermal expansion and contraction caused by frequent tangential defrosting (four-way valve 350) during winter heating at a low cost.

[0039] Light frost quick melting function: when light frost forms on the outdoor heat exchanger 310, the four-way valve 350 does not reverse, the second throttle valve 360 ​​opens more, the compressor 340 is reduced to low-frequency operation, the fan used in conjunction with the outdoor heat exchanger 310 stops, and the fan used in conjunction with the indoor heat exchanger 330 reduces its speed; when the thickness of frost on the outdoor heat exchanger 310 is medium, the four-way valve 350 does not reverse, the second throttle valve 360 ​​opens more, the compressor 340 is reduced to medium-frequency operation, the fan used in conjunction with the outdoor heat exchanger 310 stops, and the fan used in conjunction with the indoor heat exchanger 330 also stops.

[0040] When thick frost forms on the outdoor heat exchanger 310 , the tangential defrosting mode is triggered, and the outdoor heat exchanger 310 is defrosted by switching the conduction direction of the four-way valve 350 .

[0041] It can be that the first throttle valve is set as an electronic expansion valve, and the second throttle valve 360 ​​is set as an electronic expansion valve; or it can be that the first throttle valve is set as a one-way throttle valve, and the second throttle valve 360 ​​is set as an electronic expansion valve, and the one-way throttle valve includes a one-way conductive throttling passage and a one-way conductive second passage, in the cooling mode, the throttling passage is conductive, and in the heating mode, the second passage is conductive.

[0042] In some examples, such as Figure 4As shown, the control module is configured as a control board 200. Alternatively, the refrigerant heat exchange element 120 may be in a U shape or a C shape.

[0043] exist Figures 1 to 3 In the figure, reference numeral 410 is a high pressure valve and reference numeral 420 is a low pressure valve.

[0044] In some examples, such as Figure 4 As shown, the heat dissipation component 100 also includes: a first heat conductor 130, the first heat conductor 130 is arranged on the evaporation section 111, and the control board 200 is arranged on the first heat conductor 130. The evaporation section 111 and the control board 200 transfer heat through the first heat conductor 130, which can improve the heat transfer effect between the evaporation section 111 and the control board 200.

[0045] Among them, Figure 4 As shown, the first heat conducting member 130 is a first heat conducting plate, which is arranged on the side of the evaporation section 111, and the control board 200 is arranged on the side of the first heat conducting plate facing away from the evaporation section 111. The first heat conducting plate has good thermal conductivity, which can improve the heat exchange effect between the control board 200 and the evaporation section 111. Preferably, the first heat conducting plate is set as an aluminum plate.

[0046] In some examples, such as Figure 4 As shown, the heat dissipation component 100 also includes: a second heat conductive member 140, which is arranged in the condensing section 112 and abuts against the refrigerant heat exchange member 120. The condensing section 112 and the refrigerant heat exchange member 120 transfer heat through the second heat conductive member 140, which can enhance the heat transfer effect between the condensing section 112 and the refrigerant heat exchange member 120.

[0047] Among them, Figure 4 As shown, the second heat conducting member 140 is a second heat conducting plate, which is arranged on the side of the condensing section 112 and enclosed with the condensing section 112 to form a receiving channel, the portion between the two ends of the refrigerant heat exchange member 120 is located in the receiving channel, and the two ends of the refrigerant heat exchange member 120 are located outside the receiving channel, the first heat conducting plate has a relatively good thermal conductivity, and the portion between the two ends of the refrigerant heat exchange member 120 is wrapped by the condensing section 112 and the second heat conducting plate, which can improve the heat exchange effect of the refrigerant heat exchange member 120 and the condensing section 112. Preferably, the second heat conducting plate is set as an aluminum plate, and the portion between the side wall of the receiving channel and the refrigerant heat exchange member 120 is filled with thermal conductive silicone grease.

[0048] In some embodiments, Figure 4As shown, the evaporation section 111 and the condensation section 112 form a bent structure (the angle can be set to 120 degrees to 150 degrees), the evaporation section 111 is horizontally arranged, the first heat conductor 130 is arranged on the upper side of the evaporation section 111, the control board 200 is arranged on the upper side of the first heat conductor 130, the condensation section 112 is inclined and bent downward, and the second heat conductor 140 is arranged on the inclined upward side of the condensation section 112. In this scheme, the condensed water on the condensation section 112 will not flow to the control board 200 under the action of gravity, which can better avoid the short circuit of the control board 200.

[0049] In summary, the heat dissipation component provided in the embodiment of the present invention is applied to an air conditioner, the control module of the air conditioner is arranged in the evaporation section, the heat pump flow path of the air conditioner includes a refrigerant heat exchanger, the air conditioner performs cooling operation, the temperature of the control module is higher than the temperature of the evaporation section, the working medium in the evaporation section is transformed from liquid to gas to absorb the heat emitted by the control module, so as to cool the control module, and then the gaseous working medium in the evaporation section flows to the condensation section. Since the temperature of the evaporation section is always not lower than the ambient temperature, the control module will not produce condensed water and cause a short circuit; the working medium in the condensation section is transformed from gas to liquid and enters the condensation section. The heat is released, and then the liquid working fluid in the condensing section flows to the evaporating section. The temperature of the refrigerant in the refrigerant heat exchanger is lower than the temperature of the condensing section. The refrigerant in the refrigerant heat exchanger absorbs the heat released by the working fluid in the condensing section. The temperature of the refrigerant in the refrigerant heat exchanger can be set to be lower than the ambient temperature.
