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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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 the heat pipe 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.

[0035] Figures 1 to 3 A heat exchange assembly 1 of an air conditioner electrical box 2 is provided in an embodiment of the present application. A component 21 is arranged in the air conditioner electrical box 2. The heat exchange assembly 1 includes a substrate 11, a refrigerant pipe 12, a heat pipe 13 and a temperature detection module. The substrate 11 is arranged on the air conditioner electrical box 2; the refrigerant pipe 12 and the component 21 are arranged on both sides of the substrate 11 respectively, and the refrigerant pipe 12 has a plurality of curved sections 121 and straight sections 122 connected in sequence; the heat pipe 13 is located between the substrate 11 and the refrigerant pipe 12, and the heat pipe 13 is away from the substrate 11 One side of the heat pipe 13 abuts against the curved section 121 or the straight section 122 of the refrigerant tube 12, and the heat pipe 13 is movably arranged on the substrate 11 to adjust the ratio of the actual contact length of the heat pipe 13 and the refrigerant tube 12 to the maximum contact length; the temperature detection module is used to detect the temperature of the component 21; when the temperature of the component 21 is less than the first temperature threshold and decreases in stages, the heat pipe 13 moves away from the refrigerant tube 12 to make the ratio of the actual contact length of the heat pipe 13 and the refrigerant tube 12 to the maximum contact length.

[0036] It is understandable that low-temperature refrigerant circulates in the refrigerant pipe 12. When the temperature of the component 21 is greater than or equal to the first temperature threshold, the ratio of the actual contact length of the heat pipe 13 and the refrigerant pipe 12 to the maximum contact length is controlled to be 1. At this time, the heat exchange area of ​​the heat pipe 13 contacting the refrigerant pipe 12 is the largest, and the heat exchange efficiency of the heat pipe 13 is the highest, 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 less than the first temperature threshold and decreases in stages, the heat pipe 13 moves away from the refrigerant pipe 12, so that the ratio of the contact length of the heat pipe 13 and the refrigerant pipe 12 to the length of the heat pipe 13 decreases, thereby reducing the cooling loss of the air conditioner 100 and saving energy.

[0037] In some embodiments, a first slide groove 111 is provided on the substrate 11, and the heat pipe 13 is slidably connected to the first slide groove 111 to increase the heat exchange area of ​​the heat pipe 13 contacting the substrate 11 and improve the heat exchange efficiency of the heat pipe 13, so that the component 21 can be cooled quickly.

[0038] 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 capillary porous material. 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. When one end of the heat pipe 13 is heated, the liquid in the capillary tube is rapidly vaporized, and the vapor flows to the other end under the power of heat diffusion, and condenses at the other end to release heat. The liquid then flows back to the heated end along the porous material by capillary action, and the cycle continues.

[0039] In some embodiments, the thickness of the heat pipe 13 is greater than the depth of the first slide groove 111, so that the heat pipe 13 is slightly higher than the side of the substrate 11 facing the refrigerant tube 12, preventing the substrate 11 from directly contacting the refrigerant tube 12 and causing the temperature of the substrate 11 to be too low. When the temperature of the substrate 11 is lower than the dew point temperature, condensation is easily generated on the substrate 11 and causes damage to the components 21.

[0040] It is worth mentioning that the component 21 can directly contact the substrate 11 so that heat can be exchanged between the substrate 11 and the component 21 through solid heat conduction, or a certain distance can be set between the component 21 and the substrate 11. Of course, the distance between the component 21 and the substrate 11 should not be set too large.

[0041] In some embodiments, the heat exchange assembly 1 further includes a driving mechanism 14 disposed on the substrate 11 , and a power output end of the driving mechanism 14 is transmission-connected to the heat pipe 13 to move the heat pipe 13 toward or away from the refrigerant pipe 12 .

[0042] It can be understood that when the temperature of the component 21 is less than the first temperature threshold and decreases in stages, the heat pipe 13 is driven by the driving mechanism 14 to move in a direction away from the refrigerant tube 12, so as to adjust the lateral length ratio of the positive projection of the heat pipe 13 and the refrigerant tube 12 on the substrate 11 to decrease, thereby reducing the contact area between the heat pipe 13 and the refrigerant tube 12 and reducing the cooling effect on the refrigerant tube 12; when the temperature of the component 21 is greater than the second temperature threshold, the first temperature threshold is greater than the second temperature threshold, and the heat pipe 13 is driven by the driving mechanism 14 to move in a direction close to the refrigerant tube 12, thereby increasing the contact area between the heat pipe 13 and the refrigerant tube 12 and improving the heat exchange efficiency of the heat pipe 13, so that the component 21 can quickly dissipate heat.

[0043] In some embodiments, Figure 1 As shown, the driving mechanism 14 includes a motor and a gear 141 connected to the motor, a first connecting rod 142 and a rocker 143 rotatably connected to the first connecting rod 142, and a second connecting rod 144. The motor is arranged on the air conditioner electrical box 2, and the first connecting rod 142 is provided with a rack 145 meshingly connected to the gear 141, and the end of the rocker 143 away from the first connecting rod 142 is slidably connected to the second connecting rod 144, and the end of the second connecting rod 144 away from the rocker 143 is fixedly connected to the heat pipe 13. The gear 141 is driven to rotate by the motor, and the first connecting rod 142 is driven to slide up and down under the transmission action of the gear 141 and the rack 145, and the second connecting rod 144 is driven to move along the first slide groove 111 under the linkage action of the first connecting rod 142 and the rocker 143, so as to realize the movement of the heat pipe 13 on the substrate 11.

[0044] Alternatively, if Figure 3 As shown, a third slide groove 22 is provided on the air-conditioning electrical box 2, and a slider slidably connected to the third slide groove 22 is provided on the side of the first connecting rod 142 facing the air-conditioning electrical box 2 to improve the smoothness of the sliding of the first connecting rod 142.

[0045] Furthermore, if Figure 1 As shown, one end of the rocker 143 away from the first connecting rod 142 is hingedly connected to the rocker 143 through a pin shaft 146, and a second slide groove 147 for sliding the pin shaft 146 is provided on the second connecting rod 144. The second slide groove 147 is arc-shaped, and the linkage of the rocker 143 and the second connecting rod 144 can be achieved by providing the second slide groove 147.

[0046] In some embodiments, Figure 2As shown, a plurality of heat pipes 13 and second connecting rods 144 are provided, and the plurality of heat pipes 13 are arranged side by side on the substrate 11, and the plurality of second connecting rods 144 correspond one to one with the plurality of heat pipes 13. Specifically, a plurality of rockers 143 are also provided, and the plurality of rockers 143 correspond one to one with the plurality of second connecting rods 144, and the ends of the plurality of rockers 143 away from the second connecting rod 144 are hingedly connected to the first connecting rod 142, and the first connecting rod 142 is driven to slide by a motor, thereby achieving simultaneous adjustment of the heat exchange efficiency of the plurality of heat pipes 13.

[0047] In some embodiments, a through groove 112 is provided on the substrate 11, and the through groove 112 is provided in the vertical direction. The through groove 112 separates the substrate 11 into a heat dissipation area 113 and a heat absorption area 114. The component 21 is provided in the heat dissipation area 113 of the substrate 11; one end of the heat pipe 13 is provided in the heat dissipation area 113 of the substrate 11, which is referred to as the heat dissipation end; the other end is provided in the heat absorption area 114 of the substrate 11, which is referred to as the heat absorption end.

[0048] 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 113, and the temperature of the area where the substrate 11 contacts the heat absorption end of the heat pipe 13 is relatively low, forming a heat absorption area 114. Since the through groove 112 is provided, condensation formed on the heat absorption area 114 of the substrate 11 can be prevented from flowing into the side of the component 21 and causing damage to the component 21.

[0049] Furthermore, the heat pipe 13 is tilted relative to the horizontal direction, and the heat absorption end of the heat pipe 13 is higher than its heat dissipation end, so that the liquid condensed at the condensation end 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.

[0050] Optionally, the straight section 122 of the refrigerant pipe 12 is parallel to or perpendicular to the horizontal direction, as long as the ratio of the actual contact length of the heat pipe 13 and the refrigerant pipe 12 to the maximum contact length can be adjusted after the heat pipe 13 moves on the substrate 11. Figure 1 As shown, the straight section 122 of the refrigerant pipe 12 is perpendicular to the horizontal direction. Figure 4 As shown, the straight section 122 of the refrigerant pipe 12 is parallel to the horizontal direction.

[0051] like Figure 5 As shown, the embodiment of the present application also provides an air conditioner 100, including an air conditioner electrical box 2 and a heat exchange component 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 above embodiment of the heat exchange component 1, and will not be repeated here.

[0052] By adopting the above-mentioned heat exchange component 1, the heat exchange efficiency of the heat pipe 13 can be adjusted to ensure the heat dissipation required by the component 21, so that the component 21 can operate reliably. At the same time, it can reduce the impact on the power of the air conditioner 100, reduce the energy consumption of the air conditioner 100, and save energy.

[0053] like Figure 6 As shown, the embodiment of the present application provides a temperature control method of an air conditioner electrical box 2, which is applied to the air conditioner 100 as described above. The temperature control method includes the following steps:

[0054] S1. Obtain the temperature T of the component 21.

[0055] S2: If the temperature T of the component 21 is greater than or equal to the first temperature threshold T m1 , the ratio of the actual contact length of the heat pipe 13 and the refrigerant pipe 12 to the maximum contact length is controlled to be 1. At this time, the contact area between the heat pipe 13 and the refrigerant pipe 12 is the largest, and the heat exchange efficiency of the heat pipe 13 is the highest.

[0056] S3: If the temperature T of the component 21 is less than the first temperature threshold T m1 And it decreases in stages, controlling the heat pipe 13 to move away from the refrigerant pipe 12 to adjust the ratio of the actual contact length of the heat pipe 13 and the refrigerant pipe 12 to decrease, thereby reducing the contact area between the heat pipe 13 and the refrigerant pipe 12 and reducing the refrigerant loss of the air conditioner 100.

[0057] The working principle of the embodiment of the method is referred to the embodiment of the heat exchange component 11, which is not described here in detail. By adopting the above control strategy, by adjusting the heat exchange efficiency of the heat pipe 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 conditioner 100 is reasonably utilized to achieve energy saving effect.

[0058] Furthermore, the temperature control method further comprises:

[0059] If the temperature T of the component 21 is less than the second temperature threshold T m2 , the ratio of the actual contact length of the heat pipe 13 and the refrigerant pipe 12 to the maximum contact length is controlled to be 0.5, and the first temperature threshold T m1 Greater than the second temperature threshold T m2 Since the component 21 still has a heat dissipation requirement at this time, but the heat dissipation requirement is small, the contact area between the heat pipe 13 and the refrigerant pipe 12 is adjusted to a minimum value to ensure the heat dissipation requirement of the component 21 to a minimum.

[0060] T m2 is a℃, T m1 Taking (a+18)℃ as an example, the above temperature control strategy can be further described as:

[0061] When T<a℃, the ratio of the actual contact length of the heat pipe 13 and the refrigerant pipe 12 to the maximum contact length is controlled to be 0.5;

[0062] When a+3℃>T≥a℃, the ratio of the actual contact length of the heat pipe 13 and the refrigerant pipe 12 to the maximum contact length is controlled to be 0.6;

[0063] When a+7°C>T≥a+3°C, the ratio of the actual contact length of the heat pipe 13 and the refrigerant pipe 12 to the maximum contact length is controlled to be 0.7;

[0064] When a+12°C>T≥a+7°C, the ratio of the actual contact length of the heat pipe 13 and the refrigerant pipe 12 to the maximum contact length is controlled to be 0.8;

[0065] When a+18°C>T≥a+12°C, the ratio of the actual contact length of the heat pipe 13 and the refrigerant pipe 12 to the maximum contact length is controlled to be 0.9;

[0066] When T≥a+18°C, the ratio of the actual contact length of the heat pipe 13 and the refrigerant pipe 12 to the maximum contact length is controlled to be 1.
