Description

Technical Field

[0001] This invention relates to the field of new energy vehicles, specifically to a controller assembly, a compressor assembly, and a vehicle. Background Technology

[0002] With rapid economic development and increasing environmental awareness, new energy electric vehicles are developing and becoming more widespread, with a growing market share.

[0003] As an electric vehicle, the compressor is an indispensable device in the vehicle's thermal management system. Unlike traditional compressors, it requires a separate drive motor and a controller to control the drive motor.

[0004] However, the performance of power devices used in existing compressor controllers degrades as temperature rises. When the compressor starts, the heat generated by the power devices is absorbed by the controller housing, which cannot be cooled down. This can lead to the power devices malfunctioning due to high temperatures or burning out due to overheating. This situation is particularly pronounced in high-temperature environments, resulting in compressors failing to start and even instances of controller power devices burning out due to overheating. Summary of the Invention

[0005] This application provides a controller assembly, a compressor assembly, and a vehicle. The controller assembly has two cooling methods and can always be in a cooled state, thereby improving the cooling effect and reliability.

[0006] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide a controller assembly, a compressor assembly, and a vehicle, wherein the controller assembly includes: a housing and a power component; the housing is provided with a receiving cavity, a refrigerant cavity, and a support portion located between the receiving cavity and the refrigerant cavity; the power component is disposed in the receiving cavity; wherein the housing is further provided with a refrigerant inlet, the refrigerant inlet being connected to the refrigerant passage of the compressor and communicating with the refrigerant cavity; the support portion is further provided with a cooling flow channel cavity for containing coolant.

[0007] The inner wall of the accommodating cavity is equipped with a heat sink, and the power components are supported on the heat sink.

[0008] The controller assembly further includes a first plug-in, a second plug-in, and a circuit board. The power component, the first plug-in, and the second plug-in are all connected to the circuit board. The accommodating cavity includes a first sub-accommodating cavity, a second sub-accommodating cavity, and a third sub-accommodating cavity. The circuit board is disposed within the accommodating cavity and covers the first sub-accommodating cavity, the second sub-accommodating cavity, and the third sub-accommodating cavity. The housing also includes an isolation rib disposed within the accommodating cavity. The isolation rib cooperates with the circuit board to isolate the first sub-accommodating cavity, the second sub-accommodating cavity, and the third sub-accommodating cavity into independent cavities. The power component is disposed within the first sub-accommodating cavity, and the area where the refrigerant cavity and the cooling channel cavity are located covers at least part of the first sub-accommodating cavity. The second sub-accommodating cavity accommodates the first plug-in, and the third sub-accommodating cavity accommodates the second plug-in.

[0009] The controller assembly also includes a capacitor assembly located within the second sub-accommodation cavity and connected to the circuit board.

[0010] The controller assembly also includes a cover, which is connected to the housing and covers the accommodating cavity.

[0011] The power assembly includes a power device, a positioning bracket, and a thermal pad, with the thermal pad and the power device positioned on both sides of the positioning bracket.

[0012] The controller assembly also includes a temperature sensor and a processor. The temperature sensor is connected to the processor and is located inside the housing. The housing also has a coolant inlet, which is connected to the cooling channel cavity. The processor controls the opening and closing of the coolant inlet based on the temperature sensed by the temperature sensor.

[0013] This application also includes a second technical solution, providing a compressor assembly including the aforementioned controller assembly.

[0014] The compressor assembly also includes a motor and a compressor; the housing extends in the direction away from the accommodating cavity to form a mounting base, and a mounting cavity is formed in the mounting base, in which the motor is located; the mounting base and the housing are integrally formed; the compressor is connected to the mounting base.

[0015] This application also includes a third technical solution, providing a vehicle including the aforementioned compressor assembly.

[0016] The beneficial effects of this application are as follows: Unlike the prior art, the controller assembly, compressor assembly, and vehicle provided in this application have two cooling methods. When the power component is started, the housing is cooled by the flow of coolant. When the power component is working normally after starting, the housing is cooled by refrigerant, so that the housing is always in a cooled state. This improves the cooling effect of the controller assembly and improves or avoids the controller assembly failing to start or burning out due to excessively high starting temperature under high temperature conditions, thereby improving the reliability of the controller assembly.

[0027] Please see Figure 1-6In one aspect, this application provides a controller assembly 100, which includes a housing 11 and a power component 12. Specifically, the housing 11 has a receiving cavity 111, a refrigerant cavity 112, and a support portion 113 located between the receiving cavity 111 and the refrigerant cavity 112, and the power component 12 is disposed within the receiving cavity 111. Further, the housing 11 also has a refrigerant inlet 114, which is connected to the refrigerant passage (not shown) of the compressor 31 and communicates with the refrigerant cavity 112. The support portion 113 also has a cooling flow channel cavity 115 for containing coolant.

[0028] Specifically, the power component 12 is disposed within the accommodating cavity 111. During operation, it generates heat and transfers this heat to the housing 11, meaning the power component 12 can dissipate heat through the housing 11. The refrigerant cavity 112 can be circulated with refrigerant, which absorbs heat from the housing 11 through its flow, thereby cooling the housing 11. The refrigerant inlet 114 is connected to the refrigerant passage of the compressor 31 and communicates with the refrigerant cavity 112. When the compressor 31 starts, refrigerant can enter the refrigerant cavity 112 from the refrigerant passage through the refrigerant inlet 114. The support portion 113 is provided with a cooling channel cavity 115 for containing coolant. The cooling channel cavity 115 can absorb heat from the housing 11 through the flow of coolant, thereby cooling the housing 11.

[0029] When the controller assembly 100 of this application is started, the power component 12 generates heat. There is a cooling time difference during the process of refrigerant entering the refrigerant chamber 112 from the refrigerant channel and cooling the housing 11. During this time difference, coolant can enter the cooling channel chamber 115 to cool the housing 11. After the refrigerant enters the refrigerant chamber 112, it can also absorb heat from the housing 11 through refrigerant flow, thus cooling the housing 11. Specifically, when the controller assembly 100 is started, the cooling channel chamber 115 is opened, and coolant flows into the cooling channel chamber 115 for cooling. After the refrigerant enters the refrigerant chamber 112, it cools through refrigerant flow. At this time, the cooling channel chamber 115 can either activate auxiliary refrigerant for cooling or deactivate flow-saving technology. In this way, the controller assembly 100 is always in a cooled state when started, thereby improving the cooling effect of the controller assembly 100 and preventing the controller assembly 100 from failing to start or burning out due to high-temperature starting conditions, thus improving the reliability of the controller assembly 100.

[0030] Furthermore, in one specific embodiment, the temperature of the refrigerant is lower than the temperature of the coolant. When the refrigerant is normally cooling the casing 11, the cooling channel cavity 115 can be closed to stop the flow of coolant, thereby improving or preventing the coolant from reducing the cooling effect of the refrigerant on the casing 11. In another specific embodiment, the temperature of the coolant is close to the temperature of the refrigerant, and the casing 11 can be cooled simultaneously using both cooling methods. In other specific embodiments, the flow of coolant can also be controlled to cool external equipment through pipelines.

[0031] In one embodiment of this application, the inner wall of the accommodating cavity 111 is provided with a heat sink 116, and the power component 12 is supported on the heat sink 116.

[0032] Specifically, the heat sink 116 is located on the support portion 113 of the housing 11, and the power component 12 is supported on the heat sink 116. Heat can be dissipated through the heat sink 116 and transferred to the housing 11. In the above embodiment, when the controller assembly 100 is operating, the housing 11 can always be in a cooled state. That is, when the power component 12 is started, it can always dissipate heat through the heat sink 116, which can improve the heat dissipation effect, improve or prevent damage to the power component 12 due to excessively high startup temperature, and thus improve the reliability of the controller assembly 100.

[0033] In one embodiment of this application, the controller assembly 100 further includes a first plug-in 13, a second plug-in 14, and a circuit board 15. The power component 12, the first plug-in 13, and the second plug-in 14 are all connected to the circuit board 15. The accommodating cavity 111 includes a first sub-accommodating cavity 1111, a second sub-accommodating cavity 1112, and a third sub-accommodating cavity 1113. The circuit board 15 is disposed within the accommodating cavity 111 and covers the first sub-accommodating cavity 1111, the second sub-accommodating cavity 1112, and the third sub-accommodating cavity 1113. The housing 11 also includes an isolation rib 117 disposed within the accommodating cavity 111. The isolation rib 117 cooperates with the circuit board 15 to isolate the first sub-accommodating cavity 1111, the second sub-accommodating cavity 1112, and the third sub-accommodating cavity 1113 into independent cavities. Specifically, the power component 12 is disposed in the first sub-accommodating cavity 1111, and the area where the refrigerant cavity 112 and the cooling flow channel cavity 115 are located at least partially covers the first sub-accommodating cavity 1111; the second sub-accommodating cavity 1112 accommodates the first plug-in 13, and the third sub-accommodating cavity 1113 accommodates the second plug-in 14.

[0034] Therefore, the isolation rib 117 can cooperate with the circuit board 15 to isolate the first sub-accommodating cavity 1111, the second sub-accommodating cavity 1112, and the third sub-accommodating cavity 1113 into independent cavities, free from mutual interference. The first plug-in 13 and the second plug-in 14 are installed from the outside in into two mutually isolated and independent cavities, which can improve or avoid mutual interference between the current signals of the first plug-in 13 and the second plug-in 14. Specifically, in one embodiment, the first plug-in 13 may include a high-voltage plug-in, and the second plug-in 14 may include a low-voltage plug-in. By installing the high-voltage plug-in and the low-voltage plug-in from the outside in into the mutually isolated and independent second sub-accommodating cavity 1112 and third sub-accommodating cavity 1113 respectively, mutual interference between high and low voltage currents and signals is effectively shielded, thereby improving EMC (Electromagnetic Compatibility) performance. It can also reduce interference with the control of the two cooling methods.

[0035] In another specific embodiment, the first plug-in 13 may also include a low-voltage plug-in, and the second plug-in 14 may also include a high-voltage plug-in. In other embodiments, there may be other positional variations and combinations that can achieve the above-mentioned technical effects, which will not be elaborated further here.

[0036] Specifically, the area where the refrigerant cavity 112 and the cooling channel cavity 115 are located at least partially covers the first sub-accommodating cavity 1111, which can increase the cooling area, expand the cooling range, and improve the cooling effect. The power component 12 is located in the first sub-accommodating cavity 1111, which can improve the heat dissipation effect and heat dissipation efficiency, thereby improving or avoiding the inability to start or burn out due to excessive temperature, thus improving reliability.

[0037] Furthermore, the power component 12 is connected to the circuit board 15 to improve the heat dissipation efficiency of the power component 12 and reduce the temperature of the power component 12. This can also improve or prevent the circuit board 15 from failing or being damaged due to excessive temperature caused by the heat transferred by the power component 12, thereby improving the reliability of the controller assembly 100.

[0038] In one embodiment of this application, the controller assembly 100 further includes a capacitor assembly 16, which is located in the second sub-accommodation cavity 1112 and is connected to the circuit board 15.

[0039] Specifically, the capacitor assembly 16 in this embodiment includes a filter capacitor assembly 16, which is located within a relatively independent second accommodating cavity 111. This helps protect operators and the equipment itself from potential dangers such as electric shock. Furthermore, the filter capacitor assembly 16 can filter out high-frequency noise, reducing interference to other electronic components, thereby improving the stability and reliability of the controller assembly 100.

[0040] In one embodiment of this application, the controller assembly 100 further includes a cover 17, which is connected to the housing 11 and covers the accommodating cavity 111.

[0041] Specifically, the cover 17 is connected and fixed to the housing 11 and covers the accommodating cavity 111, which can protect the accommodating cavity 111 and improve or prevent the electronic components inside the accommodating cavity 111 from being damaged by the outside.

[0042] In one specific embodiment of this application, the power component 12 includes a power device 121, a positioning bracket 122, and a thermal pad 123, with the thermal pad 123 and the power device 121 disposed on both sides of the positioning bracket 122.

[0043] Specifically, the positioning bracket 122 can be used to fix and position the power device 121, while separating the power device 121 from the thermal pad 123 to improve heat dissipation efficiency and current transmission efficiency. The power device 121 can transfer heat to the thermal pad 123 through thermal convection, and the thermal pad 123 can transfer heat from the power device 121 to the heat sink 116 and the housing 11 to improve the heat dissipation effect of the power device 121, thereby improving the efficiency and lifespan of the power device 121 and thus improving its reliability.

[0044] Furthermore, in another specific embodiment, the positions of the power device 121, the positioning bracket 122, and the thermal pad 123 can also be varied. For example, the power device 121 and the positioning bracket 122 can be located on opposite sides of the thermal pad 123, and the power device 121 can transfer heat to the thermal pad 123 through contact heat conduction. In other specific embodiments, other combinations of positions for the power device 121, the positioning bracket 122, and the thermal pad 123 are also included to transfer heat from the power device 121 to the thermal pad 123 in other ways, which will not be elaborated here.

[0045] Furthermore, the thermal pad 123 may include an insulating thermal pad 123, and the heat transfer effect between the thermal pad 123 and the power device 121 can be improved by optimizing the material of the thermal pad 123, increasing the contact area and pressure, and adding other heat dissipation measures.

[0046] In one embodiment of this application, the controller assembly 100 further includes a temperature sensor 18 and a processor. The temperature sensor 18 is connected to the processor and is disposed within the accommodating cavity 111. Furthermore, the housing 11 is also provided with a coolant inlet 118, which communicates with the cooling channel cavity 115. The processor controls the opening and closing of the coolant inlet 118 based on the temperature sensed by the temperature sensor 18.

[0047] Specifically, the processor can be mounted on and connected to the circuit board 15. The temperature sensor 18 can be used to detect the temperature of the heat sink 116 and feed it back to the processor. The processor processes the temperature information and determines whether the coolant inlet 118 needs to be opened or closed.

[0048] In one embodiment, the cooling channel cavity 115 contains coolant. When the temperature sensor 18 detects that the temperature of the heat sink 116 is greater than the coolant temperature, it feeds the temperature information back to the processor. The processor then controls the coolant inlet 118 to open, allowing the coolant to flow in the cooling channel cavity 115 to cool the housing 11 and reduce the temperature of the heat sink 116. In another embodiment, when the temperature sensor 18 detects that the temperature of the heat sink 116 is less than the coolant temperature, the processor can send a signal to close the coolant inlet 118, stopping the flow of coolant in the cooling channel cavity 115 to improve or avoid affecting the cooling effect of the refrigerant. In other embodiments, when the temperature sensor 18 detects that the temperature of the heat sink 116 is equal to the coolant temperature, the processor can either send a signal to close or open the coolant inlet 118.

[0049] Furthermore, the temperature sensor 18 is specifically mounted on the heat sink 116 and is in close contact with the heat sink 116 to ensure the accuracy of the acquired temperature information.

[0050] Specifically, when the controller assembly 100 is started, the power device 121 can transfer heat to the heat sink 116, and then to the housing 11 through the heat sink 116. The temperature sensor 18 detects the temperature of the heat sink 116 and provides two methods for cooling the housing 11 through the processor, thereby reducing the temperature of the heat sink 116 and thus reducing the temperature of the power device 121.

[0051] Therefore, the controller assembly 100 of this application embodiment operates in high temperature, high power or harsh environment. By collecting the temperature of the heat sink 116 through the temperature sensor 18, the processor can provide two cooling methods for the housing 11 to cool the housing 11 according to the temperature, thereby improving the cooling effect, thereby reducing the temperature of the heat sink 116 and the power device 121, thereby improving the performance and service life of the power device 121 and improving reliability.

[0052] Specifically, in one embodiment of this application, when the power device 121 is running, before the refrigerant enters the refrigerant chamber 112, the temperature sensor 18 collects the temperature of the heat sink 116. If the temperature of the heat sink 116 is greater than the temperature of the coolant, the processor controls the coolant inlet 118 to open, and the coolant flows in the cooling channel chamber 115 to cool the housing 11. After the refrigerant enters the refrigerant chamber 112 to cool the housing 11, the temperature sensor 18 detects that the temperature of the heat sink 116 is less than or equal to the temperature of the coolant, and then closes the coolant inlet 118 to stop the flow of coolant, and continues to cool the housing 11 through the flow of refrigerant.

[0053] In the above specific embodiments, the power device 121 can always be in a cooled state during operation, which improves the cooling effect and improves or avoids the power device 121 from burning or being damaged due to excessively high start-up temperature under high temperature conditions, thereby improving the stability and reliability of the power device 121.

[0054] Please see Figure 7 In another aspect, this application also includes a second technical solution, providing a compressor assembly 200, which includes the aforementioned controller assembly 100.

[0055] Specifically, since the compressor assembly 200 includes the controller assembly 100 described in the above embodiments, it also has the beneficial effects of the controller assembly 100, which will not be repeated here.

[0056] In one embodiment of this application, the compressor assembly 200 further includes a motor and a compressor 31. The housing 11 extends in a direction away from the receiving cavity 111 to form a mounting base 21, and a mounting cavity is formed in the mounting base 21. The motor is disposed in the mounting cavity. The mounting base 21 and the housing 11 are integrally formed, and the compressor 31 is connected to the mounting base 21.

[0057] Specifically, in this embodiment, the housing 11 is a combination of the motor housing and the controller housing. The housing 11 is integrally formed with the mounting base 21. The refrigerant cavity 112 and the refrigerant are disposed on the side near the mounting base 21. The refrigerant can directly contact the housing 11 through the refrigerant cavity 112 without contact thermal resistance, thereby cooling the housing 11 and improving the heat dissipation effect.

[0058] Furthermore, the compressor 31 is connected to the mounting base 21. The compressor 31 includes a refrigerant passage. The refrigerant enters the refrigerant chamber 112 from the refrigerant passage and then cools the housing 11. There is a cooling time difference in this process. The setting of the coolant and the cooling flow channel chamber 115 can make up for the cooling time difference, so that the controller assembly 100 is always in a cooled state, and thus the compressor assembly 200 is always in a cooled state. This can improve the cooling effect of the compressor assembly 200, improve or avoid the compressor assembly 200 being damaged due to excessively high starting temperature under high temperature conditions, and thus improve the reliability of the compressor assembly 200.

[0059] Combination Figure 1-7 Specifically, after the compressor assembly 200 starts, the refrigerant flows from the refrigerant passage to the refrigerant chamber 112. Before the refrigerant reaches the refrigerant chamber 112 and cools down the controller assembly 100, the coolant flows in the cooling channel chamber 115 to provide cooling for the controller assembly 100. After the refrigerant reaches the refrigerant chamber 112 and cools down the controller assembly 100, the coolant inlet 118 can be closed to stop the flow of coolant, thereby improving or avoiding the impact of the coolant's operation on the cooling effect of the refrigerant.

[0060] Furthermore, in another embodiment of this application, after the controller assembly 100 is operating normally, when the controller assembly 100 provides cooling through refrigerant, the coolant can also be controlled to flow within the cooling channel cavity 115. The cooling channel cavity 115 can be connected to external devices, thereby cooling the external devices through the coolant, thus improving reliability.

[0061] In another embodiment of this application, a vehicle is provided, including the compressor assembly 200 described above. Specifically, the compressor assembly 200 of this application embodiment can be applied to a vehicle. In summer, under direct sunlight, the temperature inside the vehicle's front compartment is high, resulting in a high temperature for the housing 11. The compressor assembly 200 of this application embodiment can keep the housing 11 in a cooled state after startup, improving the cooling effect and mitigating or preventing damage caused by overheating during startup under high-temperature conditions, thereby improving vehicle reliability.
