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 air-conditioning 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 in the air conditioner, and removes the heat from the components through the refrigerant circulation and heat exchange of the heat pipe. Since the refrigerant pipe and the heat pipe are both fixed, the heat exchange efficiency of the heat pipe cannot be adjusted. Under refrigeration conditions, the heat dissipation of the components will remove part of the cold, causing the operating power of the air conditioner to increase, the performance of the air conditioner to decrease, and the energy consumption of the air conditioner to be high.

[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.

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 air-conditioning components: air cooling and refrigerant cooling. The refrigerant cooling method usually involves embedding a refrigerant pipe in a heat sink, fixing the heat sink to the heat-generating components of the air conditioner, and removing the heat from the components through refrigerant circulation and heat exchange with the heat pipe. Since both the refrigerant pipe and the heat pipe are fixed, the heat exchange efficiency of the heat pipe cannot be adjusted. Under refrigeration conditions, the heat dissipation of the components will remove a portion of the cold, causing the operating power of the air conditioner to increase, the performance of the air conditioner to decrease, and the energy consumption of the air conditioner to be high.

[0037] In order to solve the technical problems that the heat exchange efficiency of the heat pipe in the existing refrigerant heat dissipation method cannot be adjusted, and under refrigeration conditions, the heat dissipation of components will take away part of the cold, causing the operating power of the air conditioner to increase, the performance of the air conditioner to decrease, and the energy consumption of the air conditioner to be high, the present application provides a heat exchange component of an air conditioner electrical box and a control method thereof, and an air conditioner, which can adjust the heat exchange efficiency of multiple heat pipes to ensure the heat dissipation required by the components, so that the components can operate reliably, and at the same time can reduce the impact on the power of the air conditioner, reduce the energy consumption of the air conditioner, and save energy.

[0038] Figure 1 to Figure 2 A heat exchange component 11 of an air conditioner electrical box 2 is provided in the embodiment of the present application. Components 21 are arranged in the air conditioner electrical box 2. The heat exchange component 1 includes a substrate 11, a refrigerant pipe 12, a temperature detection module and a plurality of heat pipes 13. The substrate 11 is arranged on the air conditioner electrical box 2; the refrigerant pipe 12 is arranged on the substrate 11 and is arranged on both sides of the substrate 11 respectively with the components 21; a plurality of heat pipes 13 are arranged side by side on the substrate 11, and one end of any heat pipe 13 close to the component 21 is arranged in the heat dissipation area 112 of the substrate 11, and the other end close to the refrigerant pipe 12 is arranged in the heat absorption area 113 of the substrate 11; each heat pipe 13 is provided with a control valve 134 to control the working medium in the corresponding heat pipe 13 On and off, or multiple heat pipes 13 are movably arranged on the substrate 11 to adjust the heat exchange area between the heat pipe 13 and the heat absorption area 113 of the substrate 11; the temperature detection module (not shown in the figure) is used to detect the temperature of the component 21; when the temperature of the component 21 is higher than the first temperature threshold, some of the control valves 134 are opened or some of the heat pipes 13 are moved toward the heat absorption area 113 close to the substrate 11, so that the temperature of the component 21 reaches the first temperature threshold after heat exchange through the heat pipe 13; when the temperature of the component 21 is lower than the second temperature threshold, some of the control valves 134 are closed or some of the heat pipes 13 are moved toward the heat absorption area 113 away from the substrate 11 to reduce the cooling loss.

[0039] The heating power of the component 21 is generally within 100W, and the temperature of the component 21 can operate normally within 45℃~70℃, so the first temperature threshold can be set to 70℃, and the second temperature threshold can be set to 45℃. Under different working conditions, the heating conditions of the component 21 are different, so the real-time working temperature of the component 21 is different. The refrigerant pipe 12 can directly use the compressor suction pipe, or it can be connected in parallel with the compressor suction pipe to draw out the refrigerant cooling capacity.

[0040] It should be noted that when the air conditioner is in high-temperature cooling condition, one side of the substrate 11 is in direct contact with the component 21. The component 21 generates heat during operation, so that the portion of the substrate 11 in contact with the component 21 forms a heat dissipation area 112 with a higher temperature. The other side of the substrate 11 is in direct contact with the refrigerant pipe 12. The coldness of the refrigerant in the refrigerant pipe 12 is transferred to the substrate 11 by heat conduction, so that the portion of the substrate 11 in contact with the refrigerant pipe 12 forms a heat absorption area 113 with a lower temperature. When the temperature of the component 21 is higher than the first temperature threshold, some of the control valves 134 are opened to allow the working fluid in the heat pipe 13 to flow, and the phase change process of the working fluid evaporating at the hot end and condensing at the cold end is utilized (i.e., utilizing the latent heat of evaporation and condensation of the working fluid) to quickly conduct heat, and the heat exchange efficiency of the multiple heat pipes 13 is improved by increasing the number of heat pipes 13 participating in heat exchange. The heat of the heat dissipation area 112 of the substrate 11 is transferred to the heat absorption area 113 of the substrate 11 through the heat pipe 13 (the refrigerant pipe 12 is used as a cold source), so that the temperature of the component 21 is quickly cooled after heat exchange by the heat pipe 13, thereby ensuring the normal operation of the component 21; some of the heat pipes 13 can also be moved in the direction close to the heat absorption area 113 of the substrate 11, and the heat exchange efficiency of the heat pipe 13 is improved by increasing the heat exchange area of ​​the heat pipe 13 in contact with the heat absorption area 113 of the substrate 11, so that the temperature of the component 21 is quickly cooled after heat exchange by the heat pipe 13, thereby ensuring the normal operation of the component 21. When the temperature of the component 21 is lower than the second temperature threshold, some of the control valves 134 are closed to block the flow of the working medium in the heat pipe 13, thereby reducing the heat exchange efficiency of the multiple heat pipes 13 by reducing the number of heat pipes 13 participating in heat exchange, or reducing the heat exchange area between some heat pipes 13 and the heat absorption area 113 of the substrate 11, so as to reduce the cooling loss of the air-conditioning system and save energy.

[0041] like Figure 3As shown, in some embodiments, the heat pipe 13 adopts a closed heat pipe 13, including a tube shell 131 and a liquid wick 132 arranged on the inner wall of the tube shell 131, and the liquid wick 132 is a capillary made of a capillary porous material. End caps 133 are respectively provided at both ends of the tube shell 131 to form an invalid section, 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 11 is the condensation section, and an insulating section is provided between the evaporation section and the condensation section. The interior of the tube shell 131 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.

[0042] 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.

[0043] Preferably, the heat pipe 13 is tilted on the substrate 11, and the condensation section of the heat pipe 13 is higher than its evaporation section, so that the liquid condensed in the condensation section of the heat pipe 13 can flow 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.

[0044] In some embodiments, Figure 4 As shown, each heat pipe 13 is provided with a control valve 134 . The control valve 134 is arranged in an insulating section in the heat pipe 13 and is used to control the on-off of the working medium in the heat pipe 13 .

[0045] Open some of the control valves 134 to allow the working fluid in the heat pipe 13 to flow normally. After the working fluid is heated and evaporated in the evaporation section, it can condense in the condensation section to undergo phase change, so that the heat is quickly conducted. By increasing the number of heat pipes 13 participating in the heat exchange, the heat exchange efficiency of multiple heat pipes 13 is improved, so that the temperature of the component 21 is quickly cooled after the heat exchange by the heat pipe 13; close some of the control valves 134 to block the flow of the working fluid in the heat pipe 13, so as to reduce the heat exchange efficiency of the heat pipe 13, reduce the loss of system cooling capacity, and save energy. Of course, this embodiment can also be combined with the following embodiment in which the heat pipe 13 is movable on the substrate 11, that is, the on and off of the working fluid in some heat pipes 13 and the heat exchange area between the heat pipe 13 and the heat absorption area 113 of the substrate 11 can be controlled at the same time to achieve the effect of adjusting the heat exchange efficiency of multiple heat pipes 13.

[0046] In some embodiments, Figure 5 As shown, the heat exchange assembly 1 also includes a plurality of first drive mechanisms 14 disposed on the substrate 11 , the power output ends of the plurality of first drive mechanisms 14 correspond one-to-one to the plurality of heat pipes 13 and are transmission-connected therebetween so that the heat pipes 13 rotate toward or away from the refrigerant pipe 12 .

[0047] It should be noted that the power output end of the first driving mechanism 14 can be connected to the end of the refrigerant tube 12 close to the component 21, or can be connected to the end of the refrigerant tube 12 close to the refrigerant tube 12. When the first driving mechanism 14 drives the end of the heat pipe 13 close to the refrigerant tube 12 to rotate relative to the other end, the inclination angle θ of the heat pipe 13 on the substrate 11 is adjusted. Preferably, the rotation center of the heat pipe 13 is set to deviate from the midpoint of the heat pipe 13. Since the heat absorption area 113 of the substrate 11 is in direct contact with the refrigerant tube 12, the heat absorption area 113 of the substrate 11 forms a cold source with a temperature gradient through heat exchange between the refrigerant tube 12 and the substrate 11. If the inclination angle θ is larger, on the one hand, the contact area between the condensation section of the heat pipe 13 and the heat absorption area 113 of the substrate 11 is larger, and on the other hand, the condensation section of the heat pipe 13 is closer to the cold source center of the substrate 11, so the temperature difference between the condensation section and the evaporation section of the heat pipe 13 is larger, thereby improving the heat exchange efficiency of the heat pipe 13. After the heat exchange of the heat pipe 13, the heat of the component 21 is further dissipated more quickly; conversely, if the inclination angle θ is smaller, the heat exchange efficiency of the heat pipe 13 may be reduced.

[0048] In an optional embodiment, the first driving mechanism 14 includes a rocker 141, a first motor and a first gear 142 ( Figure 5 Only one is shown as an example, the first motor is arranged on the substrate 11, a first slider (not shown in the figure) slidably connected to the substrate 11 is arranged on the side of the rocker 141 facing the substrate 11, one end of the rocker 141 is rotatably connected to the heat pipe 13, and the other end away from the heat pipe 13 is provided with a first rack 143 meshingly connected to the first gear 142. The first motor drives the first gear 142 to rotate, and the transmission effect of the first gear 142 and the first rack 143 drives the rocker 141 to slide on the substrate 11, thereby realizing the rotation of the heat pipe 13.

[0049] Furthermore, one end of the heat pipe 13 is rotatably connected to the base plate 11 through a first pin 144, and the other end is rotatably connected to the rocker 141 through a second pin 145. The heat pipe 13 is provided with a slide groove 146 for the second pin 145 to slide. Preferably, the slide groove 146 is set as an arc groove. Figure 5 As shown, the evaporation section of the heat pipe 13 can directly conduct heat with the heat dissipation area 112 of the substrate 11 through the first pin shaft 144, and the condensation section of the heat pipe 13 is in direct contact with the heat absorption area 113 of the substrate 11. The cold energy of the refrigerant pipe 12 is transferred to the condensation section of the heat pipe 13 through the substrate 11.

[0050] In some embodiments, Figure 6As shown, the heat exchange assembly 1 also includes multiple second driving mechanisms 15, and the power output ends of the multiple second driving mechanisms 15 correspond one-to-one to the multiple heat pipes 13 and are transmission-connected therebetween, so that the heat pipes 13 move on the substrate 11 toward or away from the refrigerant pipes 12.

[0051] Since the heat absorption area 113 of the substrate 11 is in direct contact with the refrigerant tube 12, the heat absorption area 113 of the substrate 11 forms a cold source with a temperature gradient through heat exchange between the refrigerant tube 12 and the substrate 11. If the second driving mechanism 15 drives the heat pipe 13 to move in the direction close to the refrigerant tube 12, on the one hand, the contact area between the condensation section of the heat pipe 13 and the heat absorption area 113 of the substrate 11 is increased, and on the other hand, the condensation section of the heat pipe 13 is closer to the center of the cold source of the substrate 11, then the temperature difference between the condensation section and the evaporation section of the heat pipe 13 is increased, thereby improving the heat exchange efficiency of the heat pipe 13, and after heat exchange by the heat pipe 13, the heat of the components 21 is further dissipated more quickly; on the contrary, if the second driving mechanism 15 drives the heat pipe 13 to move in the direction away from the refrigerant tube 12, the heat exchange efficiency of the heat pipe 13 can be reduced.

[0052] In an optional embodiment, if Figure 6 As shown, the second driving mechanism 15 includes a slide bar 151, a second motor and a second gear 152 connected thereto. A second slider (not shown in the figure) slidably connected to the substrate 11 is provided on the side of the slide bar 151 facing the substrate 11. The second motor is provided on the substrate 11. One end of the slide bar 151 is fixedly connected to the heat pipe 13, and the other end is provided with a second rack 153 meshingly connected to the second gear 152. The second rack 153 is parallel to the heat pipe 13. The second gear 152 is driven to rotate by the second motor, and the slide bar 151 is driven to slide on the substrate 11 under the transmission action of the second gear 152 and the second rack 153, so that the heat pipe 13 moves toward or away from the refrigerant pipe 12.

[0053] In some embodiments, Figure 2 As shown, the substrate 11 is provided with a through groove 111, which divides the substrate 11 into a heat dissipation area 112 and a heat absorption area 113. The components 21 are arranged in the heat dissipation area 112 of the substrate 11, and the refrigerant pipe 12 is arranged in the heat absorption area 113 of the substrate 11. By providing the through groove 111, the condensed water generated at the upper end of the outer wall of the heat pipe 13 is guided to flow directly into the through groove 111 when flowing down along the heat pipe 13, thereby preventing the condensed water from flowing from the substrate 11 to the side of the component 21 and causing damage to the component 21.

[0054] The present application also provides an air conditioner 100, such as Figure 7As shown, it includes an air conditioner electrical box 2 and a heat exchange assembly 1 of the air conditioner electrical box 2 as described above. The working principle of the embodiment of the air conditioner 100 is referred to the aforementioned embodiment of the heat exchange assembly 1, and is not described here in detail. By adjusting the heat exchange efficiency of the plurality of heat pipes 13, the heat dissipation required by the components 21 can be accurately controlled to ensure that the components 21 work normally within the target temperature range, while reasonably utilizing the cooling capacity of the air conditioning system to achieve energy saving effect.

[0055] like Figure 8 As shown, the embodiment of the present application also provides a temperature control method of the air conditioner electrical box 2, which is applied to the air conditioner 100 as described above, and the temperature control method includes the following steps:

[0056] S1. Acquire the air conditioning working condition and the temperature of the component 21.

[0057] S2. If the air-conditioning working condition is a cooling working condition and the temperature of the component 21 is greater than the first temperature threshold, control some of the control valves 134 to be in an open state or the heat pipe 13 to move toward the heat absorption area 113 close to the substrate 11.

[0058] S3. If the air conditioning working condition is a cooling working condition and the temperature of the component 21 is lower than the second temperature threshold, some of the control valves 134 are controlled to be in a closed state or the heat pipe 13 is moved in a direction away from the heat absorption area 113 of the substrate 11.

[0059] The working principle of the embodiment of the method is referred to the aforementioned embodiment of the heat exchange assembly 1, and will not be described in detail here. By adopting the above control strategy, by adjusting the heat exchange efficiency of multiple heat pipes 13, the heat dissipation required by the component 21 can be accurately controlled to ensure that the component 21 works normally within the target temperature range, and at the same time, the cooling capacity of the air conditioning system is reasonably utilized to achieve energy saving effect.
