Description

Technical Field

[0001] This invention relates to a vehicle thermal management system, and more particularly to an integrated component. Background Technology

[0002] Currently, vehicle air conditioning systems require a liquid receiver and a gas-liquid separator to effectively operate the cooling and heating functions. Because these two components are needed, the required installation space is large, and the overall weight of the product is also large. Summary of the Invention

[0003] The purpose of this invention is to provide an integrated component that has both liquid storage and gas-liquid separation functions, and is beneficial for reducing installation space and overall product weight.

[0004] An integrated component includes a head and a housing. The housing includes a first housing, a second housing, and a third housing. The head and the first housing are fixed together, and a receiving cavity is formed between the head and the first housing. The second housing and the third housing are disposed within the receiving cavity. One end of the second housing is fixedly connected to the head, and the other end of the second housing is open. The third housing is located at least partially within the second housing through the opening. One end of the third housing is fixed to the head, and the head and the third housing are sealed together. The integrated component has a first cavity and a second cavity. The first cavity includes at least the space between the first housing and the second housing, and is used to separate and store a low-pressure gas-liquid two-phase working medium. The second cavity includes at least the space formed within the third housing, and is used to store a high-pressure gas-liquid two-phase working medium.

[0005] In the above technical solution, the integrated component includes a housing, which comprises a first housing, a second housing, and a third housing. One end of the second housing is fixedly connected to the first housing or the end cap, and the other end of the second housing is open. The third housing is located at least partially within the second housing through the opening. The first cavity includes at least the space between the first and second housings and is used to separate and store the low-pressure gas-liquid two-phase working medium. The second cavity includes at least the space formed within the third housing. When the vehicle thermal management system operates in heating mode, the refrigerant passes through the first cavity, the first housing, the second housing, and other components to separate and store the low-pressure gas-liquid two-phase working medium. When operating in cooling mode, the refrigerant passes through the second cavity, the third housing, and other components to store the high-pressure gas-liquid two-phase working medium. Both modes can be implemented in the same integrated component, which not only saves system assembly space but also reduces the overall weight of the product. Attached Figure Description

[0019] The embodiments are described below with reference to the accompanying drawings.

[0020] The vehicle's thermal management system includes an integrated unit. The heat pump system's cooling and heating functions require a receiver and a gas-liquid separator. In this embodiment, the integrated unit integrates both functions. The system passes through the first chamber of the integrated unit, which has a gas-liquid separation function, and through the second chamber, which has a liquid storage function. When the air conditioner is in heating mode, the low-temperature, low-pressure gas-liquid two-phase working medium in the evaporator passes through the liquid distribution device in the integrated unit and undergoes gas-liquid separation. The low-temperature, low-pressure gas-liquid two-phase working medium is separated into a liquid phase low-temperature, low-pressure working medium and a gas phase low-temperature, low-pressure working medium. The gas phase low-temperature, low-pressure working medium enters the compressor, while the liquid phase low-temperature, low-pressure working medium is stored at the bottom of the first chamber. When the air conditioner is in cooling mode, the high-temperature, high-pressure working medium from the condenser is stored in the second chamber of the integrated unit, and the gas-liquid two-phase high-temperature, high-pressure working medium discharged from the second chamber enters the expansion valve.

[0021] Please refer to Figure 1-4 , Figure 1 The diagram illustrates one embodiment of the structure of the integrated component 100. The integrated component 100 includes a head 11, a housing 12, a liquid dispersing device 16, a liquid suction pipe 14, and a vent pipe 15. The housing 12 includes a first housing 123, a second housing 124, and a third housing 125. The head 11 is fixedly connected to the first housing 123, forming a receiving cavity 13 between the head 11 and the first housing 123. The second housing 124 and the third housing 125 are located within the receiving cavity 13. One end of the second housing 124 is fixedly connected to the bottom of the first housing, and the other end of the second housing 124 has an opening 1241. The lower part of the third housing 125 extends into the opening 1241 and is located within the cavity of the second housing 124. One end of body 125 is fixedly connected to end cap 11, and end cap 11 is sealed to the third housing 125. The integrated component has a first cavity 126 and a second cavity 127. The first cavity 126 includes at least the space between the first housing 123 and the second housing 124. The first cavity 126 is used to separate and store low-pressure gas-liquid two-phase working medium. The second cavity 127 includes at least the space formed inside the third housing 125. The second cavity 127 is used to store high-pressure gas-liquid two-phase working medium. The first cavity and the second cavity work independently. This integrated component can realize the cooling and heating functions of the heat pump system, which requires liquid storage and gas-liquid separation functions. It can not only save the assembly space of the system, but also reduce the overall weight of the product.

[0022] Please refer to Figure 2-4In this embodiment, the end cap 11 includes a first inlet 111 and a first outlet 112. The first inlet 111 is connected to the inner cavity of the third housing 125. The first inlet 111 serves as the inlet for the high-pressure gas-liquid two-phase working medium, and the second outlet 112 serves as the outlet for the high-pressure gas-liquid two-phase working medium. The third housing 125 also includes a suction pipe 14, which is located in the inner cavity of the third housing 125. One end of the suction pipe 14 is sealed to the end cap 11 and connected to the first outlet 112. The other end of the suction pipe 14 is located in the inner cavity of the third housing 125. This part has a liquid storage function and is used to store the high-temperature gas-liquid two-phase working medium in the cooling mode.

[0023] In this embodiment, the end cap 11 also includes a second inlet 121 and a second outlet 122. The second inlet 121 serves as the inlet for the low-pressure gas-liquid two-phase working medium, and the second outlet 122 serves as the outlet for the low-pressure gas-liquid two-phase working medium. The second housing also includes an outlet pipe 15. One end of the outlet pipe 15 is fixedly connected to the end cap 11 and communicates with the second outlet 122. The other end of the outlet pipe 15 is located between the second housing 124 and the third housing 125. The bottom surface of the third housing 125 is provided with a through hole 1251. The outlet pipe 15 passes through the through hole 1251, and the outer wall of the outlet pipe 15 is sealed and fixed to the inner wall of the through hole 1251 of the third housing 125.

[0024] Please refer to Figure 3-4 In this embodiment, the integrated component also includes a liquid dispersing device 16, which is located inside the accommodating cavity 13. The liquid dispersing device 16 is opposite to the second inlet 121. The low-pressure gas-liquid two-phase working medium enters from the second inlet 121 and flows directly onto the liquid dispersing device 16. The liquid dispersing device 16 disperses the low-pressure gas-liquid two-phase working medium into small particles and then further separates it into a low-pressure liquid phase working medium and a low-pressure gas phase working medium. The low-pressure liquid phase working medium sinks and is deposited between the first shell 123 and the second shell 124. The low-pressure gas phase working medium enters the inner cavity of the second shell 124 from the opening 1241 of the second shell 124, and then enters from one end of the gas outlet pipe 15 and leaves the integrated component through the second outlet 122. This part has a gas-liquid separation function and is used to separate the low-temperature and low-pressure gas-liquid two-phase working medium in the heating mode.

[0025] Please refer to Figure 4In this embodiment, the liquid dispersing device 16 is fixedly connected to the third housing 125 and is partially located above the second housing 124. The end 1242 of the opening of the second housing 124 is partially located inside the liquid dispersing device 16. The liquid dispersing device 16 includes a liquid dispersing part 161 and a flow guiding part 162. The liquid dispersing part 161 and the flow guiding part 162 are integral structures, or they can be formed separately and then fixedly connected. The second inlet 121 is located above the liquid dispersing part 161. The liquid dispersing part 161 extends from the third housing 125 toward the first housing 123. The liquid dispersing part 161 has an arc-shaped structure and is inclined downward toward the second housing 125. The extension direction of the flow guiding part 162 is parallel to the first housing 123. The flow guiding part 162 forms a ring-shaped part downward from the liquid dispersing part 161. The liquid dispersing device can increase the contact area between the working medium and the integrated component, thereby helping to separate the gas and liquid of the working medium.

[0026] Please refer to Figure 3 and Figure 5 In this embodiment, a first filter 17 is installed at one end of the suction tube 14. A support base 18 is provided below the first filter 17. The bottom surface of the support base 18 abuts against the bottom surface of the third housing 125. The first filter 17 includes a filter support 171 and a filter screen 172. The filter screen 172 is supported by the filter support 171. The support base 18 includes an outer support seat 181 and a retainer 182. The filter support 171 and the support base 18 are respectively formed. The outer support seat 181 and the retainer 182 can be an integral structure. The retainer 182 is disposed in the outer support seat 181 and has a retaining groove 1821. The retaining groove 1821 can restrict the position of the suction tube 14. The filter support 171 and the support base 182 are also mentioned. A flow space 183 is formed between the base 18 and the suction pipe 14. The inner wall of the outer support 181 has a positioning protrusion 1811, and the outer wall of the filter support 171 has a positioning recess 1812 that matches the protrusion 1811. The protrusion 1811 and the recess 1812 are engaged. The filter support 171 also has a limiting protrusion 1711, which abuts against the upper surface of the support base 18. High-temperature, high-pressure gas-liquid two-phase working medium flows from the filter screen 172 into the first filter 17. A portion of the high-temperature, high-pressure gas-liquid two-phase working medium is stored in the formed flow space 183. The high-temperature, high-pressure gas-liquid two-phase working medium enters the suction pipe 14 from the bottom of the flow space 183. The first filter 17 helps remove impurities from the working medium in the high-pressure gas-liquid refrigerant.

[0027] The second housing 124 is provided with an oil return hole 19. The oil return hole 19 should not be blocked during assembly and welding. The oil in the low-pressure liquid phase working medium is deposited and stored at the bottom of the first cavity. The oil flows into the second housing 124 through the oil return hole. After the low-pressure gas phase working medium enters the second housing 124, it passes through the position of the oil return hole, so that the gas phase working medium carries oil and leaves the integrated part from the gas outlet pipe 15.

In heating mode, it is used to separate the low-temperature, low-pressure working medium.

[0034] The integrated component also includes a liquid dispersing device 16, which is located inside the accommodating cavity 13 and is opposite to the second inlet 121. The low-pressure gas-liquid two-phase working medium enters from the second inlet 121 and flows directly onto the liquid dispersing device 16. The liquid dispersing device 16 disperses the low-pressure gas-liquid two-phase working medium into small particles and then further separates it into a low-pressure liquid phase working medium and a low-pressure gas phase working medium. The low-pressure liquid phase working medium sinks and is deposited and stored between the first housing 123 and the second housing 124. The gas phase working medium enters the second housing 124 from the opening of the second housing 124 and then leaves the integrated component through the gas outlet pipe 15.

[0035] The liquid dispersing device 16 includes a liquid dispersing section 161 and a flow guiding section 162, which are integral structures. The second inlet 121 is located above the liquid dispersing section 161. The liquid dispersing section 161 extends from the outlet pipe 15 and the third housing 125 toward the first housing 123.

[0038] The integrated component also includes a drying package 21, which is fixed to the outer wall of the second housing 124. The fixing method can be binding or other fixing methods. The drying package 21 can absorb the moisture of the working medium in the second cavity.

[0039] Please refer to Figure 1-12 In this invention, the integrated component 100 simultaneously fulfills the functions of gas-liquid separation and liquid storage. When this device is applied to a vehicle thermal management system, the first and second chambers of the integrated component, which have both gas-liquid separation and liquid storage functions, can operate independently or simultaneously. In the figure, H-IN is the first inlet, H-OUT is the first outlet, L-IN is the second inlet, and L-OUT is the second outlet. The vehicle heat pump system includes a compressor 31, a first heat exchanger 41, a second heat exchanger 51, a third heat exchanger 61, an expansion valve 71, and the integrated component 100.

[0040] When the vehicle heat pump system is in cooling mode, the second chamber 127 of the integrated component serves as the liquid storage part. The first inlet 111 is connected to the third heat exchanger 61. The first inlet 111 is the inlet for the high-pressure gas-liquid two-phase working medium. The first outlet 112 is connected to the expansion valve 71. The first outlet is the outlet for the high-pressure gas-liquid two-phase working medium. After being compressed by the compressor 31, the working medium enters the third heat exchanger 61 for heat exchange. After heat exchange, the high-pressure gas-liquid two-phase working medium enters the storage in the third housing 125 from the first inlet 111. The high-pressure gas-liquid two-phase refrigerant enters the suction pipe 14 from the bottom of the suction pipe after being filtered by the first filter 17. Then, it flows out from the first outlet 112 and enters the expansion valve 71. After being throttled by the expansion valve 71, it enters the second heat exchanger 51 for heat exchange and finally enters the first compressor 31 to achieve cooling.

[0041] When the vehicle heat pump system is in heating mode, the first chamber 126 of the integrated component serves as a gas-liquid separation part. The second inlet 121 is connected to the second heat exchanger 51 and is the inlet for the low-pressure gas-liquid two-phase working medium. The second outlet 122 is connected to the compressor 31 and is the outlet for the low-pressure gas phase working medium. After being compressed by the compressor 31, the working medium enters the first heat exchanger 41. After heat exchange in the first heat exchanger 41, the working medium enters the second chamber, which has a liquid storage function, from the first inlet 111, and then flows out from the second outlet 112, entering the expansion valve. After being throttled by the expansion valve, it flows through the second heat exchanger 51 to release heat, thus completing the low-pressure gas-liquid two-phase working medium separation. The medium enters the first cavity 126 between the first housing 123 and the second housing 124 from the second inlet 121 for gas-liquid separation. The low-pressure gas-liquid two-phase working medium is broken into tiny particles by the dispersing device 16. The low-pressure liquid phase working medium sinks and the low-pressure gas phase working medium rises. The low-pressure liquid phase working medium is stored between the first housing 123 and the second housing 124. The second filter 20 filters impurities in the oil phase working medium deposited at the bottom. After the low-pressure gas phase working medium enters the second housing 124 from the opening 1241 of the second housing, it flows through the outlet pipe 15, making the working medium carry oil, and finally flows out of the second outlet 122 and enters the compressor 31 to achieve heating.
