Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, and in particular to a heat exchange component of an electrical box and an air conditioner. Background Art

[0002] In recent years, with the increasing integration of electronic components, their heat density has also increased dramatically. How to effectively dissipate heat has become a key factor in the development of electronic components. The same problem is faced in the field of air conditioning. At present, variable frequency air conditioners have become the mainstream of the market due to their advantages such as high efficiency and energy saving, low noise, and fast temperature adjustment. However, its components such as inverters have high power and high heat generation. If the heat cannot be discharged in time, the excessive temperature will inevitably cause damage to the inverter and seriously affect the operation of the whole machine. Therefore, when cooling at high temperature, it is necessary to reduce the temperature of the components in the air conditioner so that the air conditioner can operate reliably.

[0003] At present, there are generally two ways to dissipate heat from components: air cooling and refrigerant cooling. The refrigerant cooling method usually embeds the refrigerant pipe in the heat sink, and fixes the heat sink and the components that generate heat from the air conditioner. The heat of the components is taken away through the refrigerant circulation and heat exchange of the heat pipe. When the temperature of the heat sink is lower than the dew point temperature, the water vapor in the air is cooled and condenses on the surface of the heat sink to form condensation. The condensation flows from the refrigerant pipe side to the component side and damages the component. Utility Model Content

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0034] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0035] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0036] In the prior art, there are generally two ways to dissipate heat from components: air cooling and refrigerant cooling. The refrigerant cooling method usually embeds the refrigerant pipe in the heat sink, and fixes the heat sink and the components that generate heat in the air conditioner, and removes the heat from the components through the refrigerant circulation and heat exchange of the heat pipe. When the temperature of the heat sink is lower than the dew point temperature, the water vapor in the air is cooled and condenses on the surface of the heat sink to form condensation, which flows from the refrigerant pipe side into the component side and damages the component.

[0037] In order to solve the technical problem in the prior art that condensation is easily formed on the heat sink and damages components, the present application provides a heat exchange component of an electrical box and its temperature control method, and an air conditioner, which can prevent condensation from forming on the substrate and flowing into the components, causing component failure, while ensuring the heat dissipation requirements of the components and ensuring the working reliability of the components.

[0038] Figures 1 to 3 A heat exchange assembly 1 of an electrical box provided in an embodiment of the present application, wherein a component 21 is arranged in the electrical box 2, the heat exchange assembly 1 comprises a substrate 11, a refrigerant pipe 12, a heat pipe 13, a sliding device, and a temperature detection module, the substrate 11 is arranged on the electrical box 2, a through groove 111 is arranged on the substrate 11, the through groove 111 separates the substrate 11 into a heat dissipation area 112 and a heat absorption area 113, the orthographic projection of the component 21 on the substrate 11 is located in the heat dissipation area 112; the refrigerant pipe 12 is arranged on the substrate 11 heat absorbing area 113; the heat pipe 13 is arranged on the substrate 11, one end of the heat pipe 13 close to the component 21 is located in the heat dissipation area 112, and the other end is located in the heat absorbing area 113; the temperature detection module is used to detect the local temperature of the heat pipe 13 at the through groove 111; the sliding device includes a slider 14 slidably connected to the through groove 111, and the slider 14 slides along the through groove 111 according to the relationship between the local temperature and the dew point temperature, so that the slider 14 approaches and contacts the heat pipe 13 or the slider 14 moves away from the heat pipe 13.

[0039] By adjusting the moving position of the slider 14, the heat exchange efficiency of the heat pipe 13 can be adjusted according to the heat dissipation demand of the component 21. When the heat dissipation demand of the component 21 is high, the slider 14 approaches and contacts the heat pipe 13, thereby improving the heat exchange efficiency of the heat pipe 13; when the heat dissipation demand of the component 21 is low, the slider 14 moves away from the heat pipe 13 to the bottom of the through groove 111 or other parts, and does not directly contact the heat pipe 13, which can prevent condensation generated on the heat pipe 13 from flowing into the component 21 through the slider 14 and the substrate 11 and causing damage to the component 21. At the same time, it can reduce the cooling loss of the refrigerant pipe 12, thereby reducing the energy consumption of the air conditioner 100 and saving energy.

[0040] It is worth mentioning that the slider 14 may be made of a material with good thermal conductivity to improve the heat conduction efficiency between the slider 14 and the heat pipe 13 .

[0041] Furthermore, when the local temperature of the heat pipe 13 at the through groove 111 is greater than the dew point temperature, the slider 14 approaches and contacts the heat pipe 13 for heat dissipation; when the local temperature of the heat pipe 13 at the through groove 111 is less than or equal to the dew point temperature, the slider 14 moves away from the heat pipe 13.

[0042] It can be understood that the temperature of the area where the substrate 11 contacts the component 21 is relatively high, forming a heat dissipation area 112, and the temperature of the area where the substrate 11 contacts the refrigerant pipe 12 is relatively low, forming a heat absorption area 113. Since the through groove 111 is provided, the condensation formed on the heat absorption area 113 of the substrate 11 can be prevented from flowing into the component 21 side and causing harm to the component 21. When the local temperature of the heat pipe 13 at the through groove 111 is greater than the dew point temperature, the slider 14 approaches and contacts the heat pipe 13, increasing the heat exchange area of ​​the heat pipe 13 and improving the thermal conductivity of the heat pipe 13. At the same time, after the slider 14 fills the slide groove, it can connect the heat dissipation area 112 and the heat absorption area 113 of the substrate 11, so that solid heat conduction is achieved between the two areas of the substrate 11, thereby improving the overall heat exchange efficiency and the heat dissipation speed of the component 21. The temperature of the component 21 quickly reaches the target temperature after heat exchange through the heat pipe 13. At the same time, since the temperature of the heat pipe 13 is higher than the dew point temperature, there will be no heat on the heat pipe 13. Condensation is generated, causing the component 21 to fail, thereby ensuring the working reliability of the component 21; when the local temperature of the heat pipe 13 at the through groove 111 is less than or equal to the dew point temperature, the slider 14 moves away from the corresponding heat pipe 13 until it moves to the bottom of the slide groove to avoid condensation on the heat pipe 13. The condensation flows into the component 21 along the slider 14 and the substrate 11 and causes the component 21 to fail. When the heat dissipation demand of the temperature of the component 21 is relatively small, the slider 14 can also be away from the corresponding heat pipe 13, thereby reducing the cooling loss of the refrigerant pipe 12, thereby reducing the energy consumption of the air conditioner 100 and saving energy.

[0043] It is worth mentioning that the dew point temperature can be determined by pre-calibration, or different dew point temperatures can be selected according to the ambient temperature and ambient season, so that the dew point temperature is more consistent with the actual working conditions of the heat exchange component 1.

[0044] Optionally, the heat pipe 13 can be a closed heat pipe 13, including a tube shell and a liquid wick arranged on the inner wall of the tube shell, and the liquid wick is a capillary made of a capillary porous material. The part of the heat pipe 13 arranged in the heat dissipation area 112 of the substrate 11 is the evaporation section, and the part of the heat pipe 13 arranged in the heat absorption area 113 of the substrate is the condensation section. The inside of the tube shell is evacuated into a negative pressure state, and an appropriate amount of liquid (working fluid) with a low boiling point and easy to volatilize is filled.

[0045] When the evaporation section of the heat pipe 13 is heated, the liquid in the capillary tube vaporizes rapidly, and the vapor flows to the condensation section under the power of heat diffusion, where it condenses and releases heat. The liquid then flows back to the evaporation end along the porous material by capillary action, and the cycle continues.

[0046] In some embodiments, Figure 4 As shown, a first groove 114 is provided on the side of the substrate 11 away from the component 21, and the heat pipe 13 is embedded in the first groove 114. By providing the first groove 114, on the one hand, the positioning between the heat pipe 13 and the substrate 11 is achieved, and on the other hand, the contact area between the heat pipe 13 and the substrate 11 can be increased to improve the heat exchange efficiency of the heat pipe 13.

[0047] Furthermore, the first groove 114 is inclined relative to the horizontal plane, and one end of the first groove 114 close to the refrigerant pipe 12 is higher than the other end of the first groove 114, so that the heat pipe 13 is inclined relative to the substrate 11, and the condensation section of the heat pipe 13 is higher than its evaporation section. The liquid condensed in the condensation section of the heat pipe 13 flows back to the evaporation end more quickly under the action of gravity, thereby improving the heat exchange efficiency of the heat pipe 13 and further improving the heat dissipation speed of the component 21.

[0048] In some embodiments, the heat absorption area 113 of the substrate 11 is provided with a guide groove 115, which is arranged near the through groove 111 and communicated with the first groove 114 located in the heat absorption area 113. Since in some working conditions, the wall temperature of the heat pipe 13 will be lower than the dew point temperature and condensation will be generated, the condensation may flow into the heat dissipation area 112 of the substrate 11 along the heat pipe 13 under the action of gravity, thereby affecting the electrical performance of the component 21. Therefore, by providing the guide groove 115, the condensation generated in the condensation section of the heat pipe 13 is guided to flow directly into the guide groove 115 when flowing down the heat pipe 13, and then flow out of the heat exchange assembly 1 along the refrigerant pipe 12, thereby ensuring the normal operation of the component 21.

[0049] In some embodiments, the guide groove 115 has a guide slope 115a, and an angle is formed between the guide slope 115a and the vertical surface, so that condensation gathers in the guide groove 115 and flows out of the heat exchange component 1 along the refrigerant pipe 12 under the action of gravity. Optionally, the angle is set to 15° to 60°, for example, 30°, 35°, 40°, 45°, 50°, etc.

[0050] In some embodiments, Figure 5 and Figure 6 As shown, the sliding device also includes a slide bar 15, a motor (not shown) and a gear 16 that is transmission-connected to the power output end of the motor. The motor is arranged on the electrical box 2, the slide bar 15 is located between the base plate 11 and the electrical box 2, the slide bar 15 is provided with a rack 151 that is meshed and connected to the gear 16, and the slider 14 is fixedly connected to the slide bar 15. The gear 16 is driven to rotate by the motor, and under the transmission action of the gear 16 and the rack 151, the slide bar 15 moves along the slide groove with the slider 14. Optionally, in order to improve the stability of the movement of the slide bar 15, a slideway that is slidably connected to the slide bar 15 is provided on the electrical box 2.

[0051] In some embodiments, the substrate 11 is provided with a first stop block 117 and a second stop block 118 at both ends of the through slot 111, a first stop block 152 is provided at one end of the slide bar 15 close to the first stop block 117, and a second stop block 153 is provided at one end of the slide bar 15 close to the second stop block 118, and the first stop block 152 and the second stop block 153 are both located between the first stop block 117 and the second stop block 118. During the movement of the slide bar 15, the first stop block 152 may abut against the first stop block 117 or the second stop block 153 may abut against the second stop block 118, thereby limiting the movement stroke of the slider 14 to prevent the slider 14 from colliding with the edge of the substrate 11 and being damaged during the movement.

[0052] In some embodiments, Figure 4 As shown, a second groove 116 is provided on one side of the substrate 11 close to the refrigerant tube 12, and the refrigerant tube 12 is embedded in the second groove 116. By providing the second groove 116, on the one hand, the positioning between the refrigerant tube 12 and the substrate 11 is achieved, and on the other hand, the contact area between the refrigerant tube 12 and the substrate 11 can be increased to improve the heat exchange efficiency of the refrigerant tube 12, so that the heat absorption area 113 of the substrate 11 can be cooled more quickly.

[0053] It is worth mentioning that the refrigerant pipe 12 can be a straight pipe or a U-shaped pipe, and the shape of the second groove 116 is adapted to the direction of the refrigerant pipe 12.

[0054] Preferably, the orthographic projection of the refrigerant tube 12 on the substrate 11 at least partially covers the guide groove 115, so that after the heat pipe 13 is embedded in the first groove 114 and the refrigerant tube 12 is embedded in the second groove 116, the refrigerant tube 12 can abut against the condensation section of the heat pipe 13, and the condensation flowing into the guide groove 115 flows out of the heat exchange component 1 along the refrigerant tube 12 to prevent the condensation from flowing into the component 21 side of the substrate 11 and affecting the normal operation of the component 21.

[0055] In some embodiments, a plurality of heat pipes 13 are provided, and the plurality of heat pipes 13 are arranged side by side on the substrate 11. It should be noted that the heating power of different components 21 is different, and therefore the heat dissipation requirements of different components 21 are also different. The components 21 and the heat pipes 13 may correspond one to one, or one component 21 may correspond to a plurality of heat pipes 13 to improve the heat dissipation efficiency of the components 21.

[0056] like Figure 7As shown, the embodiment of the present application also provides an air conditioner 100, including an electrical box 2 and a heat exchange component 1 of the electrical box 2 as described above. The working principle of the embodiment of the air conditioner 100 refers to the above-mentioned embodiment of the heat exchange component 1, and will not be repeated here. With the above-mentioned heat exchange component 1, by adjusting the moving position of the slider 14, the heat exchange efficiency of the heat pipe 13 can be adjusted according to the heat dissipation demand of the component 21. When the heat dissipation demand of the component 21 is high, the slider 14 approaches and contacts the heat pipe 13, thereby improving the heat exchange efficiency of the heat pipe 13; when the heat dissipation demand of the component 21 is low, the slider 14 moves away from the heat pipe 13 and moves to the bottom or other parts of the through groove 111, without direct contact with the heat pipe 13, which can avoid the condensation generated on the heat pipe 13 from flowing into the component 21 through the slider 14 and the substrate 11 and causing damage to the component 21, and at the same time can reduce the cold loss of the refrigerant pipe 12, thereby reducing the energy consumption of the air conditioner 100 and saving energy.

[0057] like Figure 8 As shown, the embodiment of the present application provides a temperature control method of an electrical box 2, which is applied to the air conditioner 100 as described above. The temperature control method includes the following steps:

[0058] S1. Obtaining the local temperature of the heat pipe 13 at the through groove 111.

[0059] S2. According to the relationship between the local temperature and the dew point temperature, the slider 14 is controlled to move along the through groove 111 so that the slider 14 contacts the heat pipe 13 for heat dissipation or the slider 14 moves away from the heat pipe 13 .

[0060] The working principle of the embodiment of the method is referred to the embodiment of the heat exchange assembly 1, which is not described here in detail. By adopting the above control strategy, the heat exchange efficiency of the heat pipe 13 can be adjusted according to the heat dissipation demand of the component 21 by adjusting the moving position of the slider 14, so as to accurately control the heat dissipation required by the component 21, ensure that the component 21 works normally within the target temperature range, and prevent the condensation generated on the heat pipe 13 from flowing into the component 21 through the slider 14 and the substrate 11, thereby causing damage to the component 21.

[0061] Furthermore, the temperature control method further comprises:

[0062] If the local temperature of the heat pipe 13 at the through groove 111 is greater than the dew point temperature, the control slider 14 moves in a direction close to the heat pipe 13 and contacts the heat pipe 13 .

[0063] If the local temperature of the heat pipe 13 at the through groove 111 is less than or equal to the dew point temperature, the slider 14 is controlled to move in a direction away from the heat pipe 13 .

[0064] Furthermore, the temperature control method further comprises:

[0065] The local temperatures of the plurality of heat pipes 13 at the through grooves 111 are obtained; and the slider 14 is controlled to move to the heat pipe 13 with the highest local temperature.

[0066] Since the heating power of different components 21 is different, the heat dissipation requirements of different components 21 are also different, so the real-time temperatures of multiple heat pipes 13 are also different. After obtaining the local temperatures of multiple heat pipes 13 at the through groove 111, the heat pipe 13 with the highest local temperature can be obtained, and then the component 21 corresponding to the heat pipe 13 is used as the component 21 with the highest heat dissipation priority, and the control slider 14 is moved to the heat pipe 13 with the highest local temperature to improve the heat exchange efficiency of the heat pipe 13, so that the temperature of the corresponding component 21 reaches the target temperature faster; when the temperature of the corresponding component 21 reaches the target temperature, the heat pipe 13 with the highest local temperature is determined again, and the control slider 14 is moved to the heat pipe 13 with the highest local temperature.
