Description

Technical Field

[0001] The present application relates to the technical field of heat dissipation devices, and in particular to a water-cooled heat dissipation controller, an electrical box, and an air-conditioning system. Background Art

[0002] With the rapid development of air conditioning system functionality, controllers are also rapidly being replaced. As a key component in air conditioning systems, the heat dissipation performance of the controller directly affects control performance and the operational reliability of the air conditioning system. Because controllers are equipped with control components such as the CPU and power module, these components generate heat during operation. Failure to dissipate this heat in a timely manner can cause the heating components to burn out, seriously affecting the quality and reliability of the controller.

[0003] Currently, controller cooling methods primarily include air cooling and water cooling. Traditional air cooling, however, is less than ideal due to the controller being installed inside the electrical enclosure. For water cooling, some existing products utilize cooling pipes extending from the entire unit and distributed near the controller. This approach imposes significant structural limitations, potentially impacting overall performance under harsh operating conditions and increasing the risk of refrigerant leakage. Therefore, how to separate the controller from the overall unit, dissipating heat autonomously under harsh operating conditions, and thus avoiding traditional air cooling, remains a pressing technical challenge.

The first water inlet and the first water outlet of the water cooling plate are both connected to the flow channel. The temperature of the first water inlet of the water cooling plate is higher than the temperature of the first water outlet.

[0008] The first end of the liquid cooling pipe passes through the controller body and the base plate in sequence and is connected to the first water outlet of the water cooling plate. The second end of the liquid cooling pipe passes through the controller body and the base plate in sequence and is connected to the first water inlet of the water cooling plate.

[0009] In one possible implementation, a throttling element is provided at the first end of the liquid cooling tube, the third water inlet of the throttling element is connected to the first end of the liquid cooling tube, and the third water outlet of the throttling element is connected to the first water inlet of the water cooling plate to control the flow rate of the cooling liquid flowing into the water cooling plate from the liquid cooling tube.

[0010] In a possible implementation, a first temperature detection device and / or a second temperature detection device are included, wherein the first temperature detection device is configured to detect the temperature of the second end of the liquid cooling tube, and the second temperature detection device is configured to detect the ambient temperature;

[0011] If the temperature of the second end of the liquid cooling tube is greater than a first temperature threshold, and / or the ambient temperature is greater than a second temperature threshold, the opening of the throttling element is controlled to increase, wherein the first temperature threshold is greater than the second temperature threshold.

[0012] In one possible implementation, if the temperature of the first end of the liquid cooling tube is less than a third temperature threshold, and / or the ambient temperature is less than a fourth temperature threshold, then the opening of the throttling element is controlled to decrease, wherein the third temperature threshold is less than the first temperature threshold, and the fourth temperature threshold is less than the second temperature threshold.

[0013] In one possible implementation, the heat sink includes a water pump, which is provided with a second water inlet and a second water outlet. The second water inlet of the water pump is connected to the first water inlet of the water cooling plate, and the second water outlet of the water pump is connected to the first end of the liquid cooling pipe.

[0014] In a possible implementation, a heat dissipation fin is provided on a side of the water cooling plate facing away from the controller body, a first end of the heat dissipation fin is connected to the water cooling plate, and a second end of the heat dissipation fin extends in a direction away from the controller body.

The coolant flowing in the liquid cooling pipe quickly transfers the heat to the water cooling plate. The coolant in the water cooling plate exchanges heat with the air in the external environment, thereby transferring the heat to the external environment away from the heating element. The coolant after cooling enters the liquid cooling pipe again to take away the heat of the heating element. The heat of the heating element is then taken away by the coolant circulation, thereby achieving efficient heat dissipation of the heating element, transferring the heat in time, avoiding the heating element from being burned, and ensuring the quality and reliability of the controller.

[0032] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0034] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.

[0035] In the existing technology, existing controller cooling methods mainly include air cooling and water cooling. Traditional air cooling is less than ideal because the controller is installed inside the electrical box. For water cooling, some existing products use cooling pipes extending from the entire unit and distributed near the controller for heat dissipation. This method not only imposes significant structural restrictions on the entire unit, potentially affecting overall performance under harsh operating conditions, but also increases the risk of refrigerant leakage. Therefore, how to separate the controller from the entire unit and dissipate heat independently under harsh operating conditions, while avoiding traditional air cooling, has become a technical challenge to be solved.

[0036] In order to solve the technical problems that the existing controller adopts the unsatisfactory heat dissipation effect of the air cooling method, and the water cooling method of directly drawing the coolant pipe from the whole machine will affect the performance of the whole machine and increase the risk of refrigerant leakage, the present application provides a water-cooled heat dissipation controller and air-conditioning system, which adopts independent heat dissipation and is safer. At the same time, it can dissipate heat for heating elements with severe heat in a targeted manner, thereby improving the heat dissipation efficiency.

[0037] Figure 1 and Figure 2A water-cooled heat dissipation controller 1 provided in an embodiment of the present application includes a controller body 11 and a heat sink 12. The controller body 11 includes a first side 11a and a second side 11b arranged opposite to each other. The first side 11a of the controller body 11 is provided with a substrate 111, and a heating element 112 is provided on the side of the substrate 111 facing away from the controller body 11; the heat sink 12 includes a liquid cooling pipe 121 and a water cooling plate 122. Cooling liquid flows inside the liquid cooling pipe 121. The liquid cooling pipe 121 is arranged on the peripheral side of the heating element 112, and the water cooling plate 122 is arranged on the second side 11b of the controller body 11. The water cooling plate 122 is connected to the liquid cooling pipe 121 to cool the cooling liquid in the liquid cooling pipe 121.

[0038] It should be noted that the heating element 112 can be a component with high heat generation and high heat dissipation requirements, such as a CPU and a power module. It is understandable that when the entire machine is turned on, the heat generated by the heating element 112 is transferred to the liquid cooling pipe 121 through heat conduction. The coolant circulating in the liquid cooling pipe 121 quickly transfers the heat to the water cooling plate 122. The coolant in the water cooling plate 122 exchanges heat with the air in the external environment, thereby transferring the heat to the external environment away from the heating element 112. The cooled coolant then enters the liquid cooling pipe 121 to take away the heat of the heating element 112. The heat of the heating element 112 is then taken away by the coolant circulation, thereby achieving efficient heat dissipation of the heating element 112, transferring the heat in time, avoiding the burning of the heating element 112, and ensuring the quality and reliability of the controller. Compared to the method of drawing cooling pipes from the entire machine to dissipate heat to the controller, the water-cooled heat dissipation controller 1 provided in the embodiment of the present application does not need to draw refrigerant from the entire machine and adopts independent heat dissipation, which makes the layout of the entire machine more diverse and safer, and does not affect the cooling performance of the entire machine. Compared with the traditional air-cooled heat dissipation method, the liquid cooling pipe 121 can be adjusted according to the demand, and the heat dissipation of the heating element 112 with severe heat generation can be targeted to improve the heat dissipation efficiency. At the same time, the controller body 11 and the heat sink 12 are integrated together to achieve integration and high integration, saving space and facilitating the layout of the controller on the electrical box 2.

[0039] It should be emphasized that for the same controller, multiple heating elements 112 can be set at the same time. In this case, the direction of the corresponding liquid cooling tube 121 is designed accordingly according to the distribution position of the heating element 112, so that the liquid cooling tube 121 is distributed around the heating element 112.

[0040] In addition, the substrate 111 can be a rigid printed circuit board (PCB) or a glass substrate 111, and the heating element 112 can be connected to the substrate 111 through solder or epoxy resin using COB (Chips on Board), COG (Chips on Glass), POB (Package on Board) or POG (Package on Glass) technology.

[0041] Alternatively, as Figure 1 As shown, the first side 11a of the controller body 11 is provided with a seating groove, and the substrate 111 is embedded in the seating groove of the controller body 11. The first side 11a of the controller body 11 may also be provided with a plurality of clips 11c (for example, four clips 11c are provided in the figure). After the substrate 111 is embedded in the seating groove of the controller body 11, the plurality of clips 11c limit the substrate 111 and prevent the substrate 111 from moving relative to the controller body 11.

[0042] In some embodiments, the water-cooling plate 122 is provided with a first water inlet 122a, a flow channel 122c and a first water outlet 122b. The first water inlet 122a and the first water outlet 122b are both arranged on the side of the water-cooling plate 122 facing the controller body 11, the flow channel 122c is arranged in the water-cooling plate 122, the first water inlet 122a and the first water outlet 122b of the water-cooling plate 122 are both connected with the flow channel 122c, and the temperature of the first water inlet 122a of the water-cooling plate 122 is higher than the temperature of the first water outlet 122b; the first end of the liquid cooling tube 121 passes through the controller body 11 and the substrate 111 in sequence, and is connected with the first water outlet 122b of the water-cooling plate 122, and the second end of the liquid cooling tube 121 passes through the controller body 11 and the substrate 111 in sequence, and is connected with the first water inlet 122a of the water-cooling plate 122.

[0043] Specifically, the heat generated by the heating element 112 is transferred to the coolant in the liquid cooling tube 121 through heat conduction. The heated coolant flows into the water cooling plate 122 from the second end of the liquid cooling tube 121 through the first water inlet 122a. After passing through the flow channel 122c, the coolant exchanges heat with the air of the external environment. The cooled coolant then enters the liquid cooling tube 121 from the first water outlet 122b through the second end of the liquid cooling tube 121. The heat of the heating element 112 is then taken away by the coolant circulation, thereby achieving efficient heat dissipation of the heating element 112.

[0044] Furthermore, the controller body 11 is provided with a first opening corresponding to the first water outlet 122b, and the substrate 111 is provided with a second opening corresponding to the first opening. The first end of the liquid cooling tube 121 passes through the second opening and the first opening in sequence and is connected with the first water inlet 122a; the controller body 11 is provided with a third opening corresponding to the first water inlet 122a, and the substrate 111 is provided with a fourth opening corresponding to the third opening. The second end of the liquid cooling tube 121 passes through the fourth opening and the third opening in sequence and is connected with the first water outlet 122b; then glue is poured around the substrate 111, the second opening and the fourth opening to fix the substrate 111 on the controller body 11, and at the same time, the liquid cooling tube 121 is fixed on the substrate 111 to prevent the liquid cooling tube 121 from shaking relative to the substrate 111, thereby protecting the substrate 111.

[0045] In order to ensure the sealing of the water-cooling plate 122, a sealing design can be made at the first water inlet 122a and the first water outlet 122b. For example, sealing members (such as existing rubber sealing rings, etc.) are respectively provided at the first water inlet 122a and the first water outlet 122b; or, sealant is respectively applied to the first water inlet 122a and the first water outlet 122b to prevent the coolant from leaking from the first water inlet 122a and the first water outlet 122b and affecting the heat dissipation performance of the water-cooled heat dissipation controller 1. At the same time.

[0046] Alternatively, as Figure 3 As shown, the flow channel 122c can be set to an S shape and cover the water cooling plate 122 as much as possible to make the contact area between the coolant and the water cooling plate 122 as large as possible, which is conducive to transferring the heat of the coolant through the water cooling plate 122 and improving the heat dissipation efficiency.

[0047] In some embodiments, a throttling element 123 is provided at the first end of the liquid cooling tube 121, the third water inlet of the throttling element 123 is connected to the first end of the liquid cooling tube 121, and the third water outlet of the throttling element 123 is connected to the first water inlet 122a of the water cooling plate 122 to control the flow rate of the cooling liquid flowing from the liquid cooling tube 121 to the water cooling plate 122.

[0048] By setting the throttling element 123, the opening of the throttling element 123 can be adjusted according to the operating conditions, thereby controlling the flow of coolant flowing from the liquid cooling pipe 121 to the water cooling plate 122, so that the heating element 112 can operate normally within the appropriate operating temperature range.

[0049] Optionally, the throttling element 123 adopts a thermal expansion valve, an electronic expansion valve, etc. in the prior art. Since the control accuracy of the electronic expansion valve is better than that of the thermal expansion valve and the operating range of the electronic expansion valve is wider, it is preferred to use an electronic expansion valve.

[0050] Furthermore, the water-cooled heat dissipation controller 1 includes a first temperature detection device 124 and / or a second temperature detection device 125, the first temperature detection device 124 is configured to detect the temperature T1 of the second end of the liquid cooling tube 121, and the second temperature detection device 125 is configured to detect the ambient temperature Ts; if the temperature T1 of the first end of the liquid cooling tube 121 is greater than the first temperature threshold Tm1, and / or the ambient temperature Ts is greater than the second temperature threshold Tm2, then the opening of the throttling element 123 is controlled to increase, wherein the first temperature threshold is greater than the second temperature threshold.

[0051] It should be noted that the first temperature detection device 124 can be an existing NTC thermistor. The NTC thermistor is placed at the second end of the liquid cooling tube 121 to detect the temperature of the second end of the liquid cooling tube 121 in real time. The temperature of the second end of the liquid cooling tube 121 is the terminal temperature of the liquid cooling tube 121. The temperature of the second end of the liquid cooling tube 121 can represent the amount of heat generated by the heating element 112. If T1>Tm1, it means that the heating element 112 has a large amount of heat generated and a high heat dissipation requirement. In this case, the opening of the throttling element 123 can be increased to increase the flow rate of the coolant through the first water inlet 122a, thereby increasing the circulation of the coolant and removing more heat. Similarly, the second temperature detection device 125 can be an existing NTC thermistor. The NTC thermistor can be placed around the first water inlet 122a of the water cooling plate 122 to detect the temperature of the first water inlet 122a of the water cooling plate 122 in real time. The ambient temperature can also represent the amount of heat generated by the heating element 112. If Ts>Tm2, it means that the heat generated by the heating element 112 is large and the heat dissipation requirement is high. At this time, the opening of the throttling element 123 can be increased to increase the flow rate of the coolant through the first water inlet 122a and increase the coolant circulation to take away more heat.

[0052] Further, if the temperature of the first end of the liquid cooling tube 121 is lower than a third temperature threshold, and / or the ambient temperature is lower than a fourth temperature threshold, then the opening of the control throttling element 123 is reduced, wherein the third temperature threshold is lower than the first temperature threshold, and the fourth temperature threshold is lower than the second temperature threshold.

[0053] If T1 < Tm3, the heat generated by the heating element 112 is low, and the heat dissipation requirement is low. In this case, the opening of the large throttling element 123 can be reduced, reducing the flow of coolant through the first water inlet 122a, thereby saving energy. Similarly, if Ts < Tm4, the heat generated by the heating element 112 is low, and the heat dissipation requirement is low. In this case, the opening of the large throttling element 123 can be reduced, reducing the flow of coolant through the first water inlet 122a, thereby saving energy.

[0054] If Tm3≤T1≤Tm1, or Tm4≤Ts≤Tm2, then the current opening of throttling element 123 can be maintained. In this way, by adjusting the opening of throttling element 123, the flow rate of coolant flowing from liquid cooling pipe 121 to water cooling plate 122 is controlled, allowing heating element 112 to operate normally within the appropriate operating temperature range, thus achieving self-detection feedback regulation of the controller.

[0055] In some embodiments, the heat sink 12 also includes a water pump 126, which is provided with a second water inlet and a second water outlet. The second water inlet of the water pump 126 is connected to the first water inlet 122a of the water cooling plate 122, and the second water outlet of the water pump 126 is connected to the first end of the liquid cooling pipe 121.

[0056] The water pump 126 drives the coolant to circulate in the flow channel 122 c . After the low-temperature coolant enters the flow channel 122 c from the first water inlet 122 a , it flows out through the first water outlet 122 b to remove the heat generated by the heating element 112 .

[0057] Optionally, the radiator also includes a fan, which can increase the air flow rate on the side of the water cooling plate 122 away from the controller body 11, improve the heat exchange efficiency between the coolant and the air, and use air cooling and water cooling to further improve the heat dissipation efficiency.

[0058] In some embodiments, a heat dissipation fin 122d is provided on a side of the water cooling plate 122 away from the controller body 11 , a first end of the heat dissipation fin 122d is connected to the water cooling plate 122 , and a second end of the heat dissipation fin 122d extends away from the controller body 11 .

[0059] The heat dissipation fins 122d increase the heat dissipation area. After the coolant passes through the flow channel 122c, part of the heat is exchanged with the air at the water-cooling plate 122, and part of the heat is transferred to the heat dissipation fins 122d through the water-cooling plate 122, thereby improving the heat dissipation efficiency and further ensuring the working reliability of the controller.

[0060] Optionally, a plurality of heat dissipating fins 122d are provided, and the plurality of heat dissipating fins 122d are distributed in a linear array on the water-cooling plate 122. The heating element 112 has many models, and the sizes of the first water inlet 122a, the first water outlet 122b, and the flow channel 122c vary accordingly. The number of heat dissipating fins 122d can be determined through simulation or experimentation based on the determined sizes of the first water inlet 122a, the first water outlet 122b, and the flow channel 122c, and is not specifically limited in this application.

[0061] It is understandable that the specific structure of the aforementioned heat dissipation fins 122d can be optimized based on the shape of the rectangular heat dissipation fins 122d already available in the prior art. Of course, it can also be designed separately according to the specific heat dissipation requirements.

[0062] In some embodiments, the heating element 112 includes a first heating element 112a and a second heating element 112b. The first heating element 112a generates more heat than the second heating element 112b. The first end of the liquid cooling tube 121 is connected to the water pump 126, and the second end of the liquid cooling tube 121 passes through the first heating element 112a and the second heating element 112b in sequence. For example, the first heating element 112a may be a CPU, and the second heating element 112b may be a power module. Since the first heating element 112a generates more heat than the second heating element 112b, the heat dissipation priority of the first heating element 112a is higher than that of the second heating element 112b. The liquid cooling tube 121 is preferentially arranged around the first heating element 112a and then around the second heating element 112b. That is, heat is preferentially dissipated in areas with severe local heating, thereby ensuring the reliability of the controller.

[0063] Optionally, the heating element 112 may further include a third heating element, a fourth heating element, ..., an Nth heating element, where N≥2. As the heat dissipation priority gradually decreases, the liquid cooling pipe 121 sequentially passes through the third heating element, the fourth heating element, ..., the Nth heating element.

[0064] Furthermore, the orthographic projection of the liquid cooling tube 121 on the controller body 11 covers the orthographic projection of the heating element 112 on the controller, so that the liquid cooling tube 121 is located directly above the heating element 112, which is conducive to better transfer of heat generated by the heating element 112 to the liquid cooling tube 121 through heat conduction.

[0065] In some embodiments, as Figure 4 As shown, a bracket 11d is provided at the edge of the controller body 11, and a mounting hole is provided on the bracket 11d. Fasteners can be provided on the mounting holes, and the fasteners can be existing screws, etc. The maximum distance between the bracket 11d and the controller body 11 is greater than the maximum distance between the liquid cooling pipe 12 and the controller body 11, thereby facilitating the installation of the water-cooled heat dissipation controller 1 on the shell 21 of the electrical box 2.

[0066] like Figure 5 As shown, the embodiment of the present application further provides an electrical box 2, comprising a shell 21 and the water-cooling heat dissipation controller 1 as described above, the shell 21 is provided with a receiving cavity, and the water-cooling heat dissipation controller 1 is arranged in the receiving cavity of the shell 21.

[0067] The embodiment of the electrical box 2 includes all technical solutions of all the embodiments of the water-cooling heat dissipation controller 1 described above, and its working principle and technical effects achieved are also exactly the same, which will not be repeated here.

[0068] Optionally, the housing 21 is further provided with heat dissipation holes communicating with the accommodating cavity, so that the heat of the heating element 112 can be better discharged from the accommodating cavity.

[0069] The embodiment of the present application further provides an air conditioning system, comprising the electrical box 2 as described above.

[0070] By providing the water-cooled heat dissipation controller 1 and adopting autonomous heat dissipation, the layout on the air conditioner is made more diversified, the safety is higher, and the cooling performance of the air conditioner system is not affected.
