Detailed implementation manners

[0036] The present invention will be described in detail below in combination with the specific implementation manners shown in the drawings. However, these implementation manners do not limit the present invention, and any structural, method, or functional transformation made by those of ordinary skill in the art based on these implementation manners is included in the protection scope of the present invention.

[0037] For new energy vehicles, which are different from traditional automotive air-conditioning systems, new energy vehicles mainly use heat management integrated modules for heat management. The main factor for new energy vehicles to introduce heat management integrated modules is that pure electric vehicles or plug-in hybrid vehicles that support pure electric driving can no longer use the engine as a stable heat source for heating. Therefore, most current new energy vehicles introduce heat management integrated module systems.

[0038] The working principle of the thermal management integrated module is to transfer heat from a place with a lower temperature to a place with a higher temperature, so as to achieve the effect of refrigeration or heating. To achieve the above effects, the thermal management integrated module is usually designed to take into account both refrigeration and heating conditions. Generally, the thermal management integrated module is designed to include multiple valves, and the working mode of the thermal management integrated module is switched by switching the valves. Moreover, a refrigerant needs to be injected into the thermal management integrated module, and the refrigerant absorbs the ambient heat to achieve refrigeration, or releases heat to the vehicle cabin to achieve the temperature rise of the vehicle interior.

[0039] For the thermal management integrated module, its assembly structure is complex and it is difficult to control the production quality. Therefore, the present application provides an intelligent production line 100 for the thermal management integrated module, which is used to produce the thermal management integrated module 200, improve the production efficiency of the thermal management integrated module, and control the production quality of the thermal management integrated module.

[0040] As Figure 1 shown, it shows a schematic diagram of the intelligent production line 100 for the thermal management integrated module provided by the embodiment of the present application. As Figure 1 shown, the intelligent production line 100 for the thermal management integrated module provided by the embodiment of the present application includes a feeding part 11, a first assembly part 12, a first testing part 13, a second assembly part 14, a second testing part 15 and a finished product part 17.

[0041] Among them, the feeding part 11 is located at the starting section of the intelligent production line 100 for the thermal management integrated module. The first assembly part 12 is located downstream of the feeding part 11 and is used to assemble the refrigerant side components of the thermal management integrated module 200. The first testing part 13 is located downstream of the first assembly part 12 and is used to test the refrigerant side components. The first testing part 13 includes a testing module 131. The second assembly part 14 is located downstream of the feeding part 11 and is used to assemble the chilled water side components of the thermal management integrated module 200. The second testing part 15 is located downstream of the second assembly part 14 and is used to test the chilled water side components. The second testing part 15 includes a testing module 131. The finished product part 17 is located downstream of the second testing part 15 and is used to output the finished product.

[0042] According to the above description, the intelligent production line 100 of the thermal management integration module provided by the embodiment of the present application provides a feeding section 11. The feeding section 11 conveys to the intelligent production line 100 of the thermal management integration module various components for assembling the thermal management integration module 200, realizing the automatic feeding operation of the intelligent production line 100 of the thermal management integration module. Moreover, through the first assembly section 12, the various components provided by the feeding section 11 for assembling the thermal management integration module 200 are assembled to form the refrigerant side components of the thermal management integration module 200. After completing the assembly work of the refrigerant side components, the second assembly section 14 is used to complete the assembly work of the chilled water side components of the thermal management integration module 200. Thus, the overall assembly of the thermal management integration module 200 is completed, and the finished product section 17 is provided to output the finished product of the assembled thermal management integration module 200. The present application provides a complete production process for the thermal management integration module 200, greatly improving the production efficiency of the thermal management integration module 200.

[0043] In the production process of the thermal management integration module 200, the intelligent production line 100 of the thermal management integration module provided by the embodiment of the present application inserts a first testing section 13. The first testing section 13 is located downstream of the first assembly section 12. After the first assembly section 12 completes the assembly of the refrigerant side components of the thermal management integration module 200, the refrigerant side components of the thermal management integration module 200 are first tested by the first testing section 13. Only the refrigerant side components of the thermal management integration module 200 that pass the test can enter the next production link of the intelligent production line 100 of the thermal management integration module, that is, only the refrigerant side components of the thermal management integration module 200 that pass the test can enter the second assembly section 14. By setting the first testing section 13 downstream of the first assembly section 12, the present application can detect unqualified products as early as possible, avoiding further processing of unqualified refrigerant side components of the thermal management integration module, thereby improving the product qualification rate of the thermal management integration module 200 and increasing the production efficiency.

[0044] The intelligent production line 100 of the thermal management integration module provided by the embodiment of the present application sets a second testing section 15 downstream of the second assembly section 14. The second testing section 15 tests the chilled water side components of the thermal management integration module 200. Only the thermal management integration module 200 that passes the test of the second testing section 15 can be used as a qualified finished product of the thermal management integration module 200.

[0045] As an optional implementation manner, the intelligent production line 100 of the thermal management integration module provided by the embodiment of the present application further includes a third testing section 16. The third testing section 16 includes a visual inspection module 161 to determine whether the product is qualified by the appearance of the product. The third testing section 16 is located between the second testing section 15 and the finished product section 17.

[0046] The intelligent production line 100 of the thermal management integrated module provided by the embodiment of the present application tests the refrigerant-side components of the thermal management integrated module 200 through the first test unit 13, so as to discover problems as early as possible, avoid unnecessary processing, and reduce production losses. Moreover, the second test unit 15 tests the chilled water-side components of the thermal management integrated module 200, so that the quality inspection of the thermal management integrated module 200 products can be completed in the production process, and the production quality of the thermal management integrated module 200 products can be controlled.

[0047] As an optional implementation manner, in the embodiment of the present application, the first test unit 13 includes a test module 131, and the test module 131 can be used to test whether the refrigerant-side components of the thermal management integrated module 200 are qualified. When the test module 131 performs a qualification test on the refrigerant-side components of the thermal management integrated module 200, it is necessary to detect the sealing performance of the refrigerant-side components. For the refrigerant-side components, the factor affecting their sealing performance lies in whether each valve in the refrigerant-side components can function well. In this regard, the test module 131 provided by the embodiment of the present application checks whether there is a leakage problem in each valve of the refrigerant-side components.

[0048] Among the refrigerant-side components of the thermal management integrated module 200, there are solenoid valves and / or expansion valves.

[0049] As Figure 2 shown, as an optional implementation manner, in the intelligent production line 100 of the thermal management integrated module provided by the embodiment of the present application, the first assembly unit 12 includes an expansion valve assembly module 121 and a solenoid valve assembly module 122. Specifically, the expansion valve assembly module 121 is used to provide expansion valve assembly during the assembly process of the thermal management integrated module 200, and the solenoid valve assembly module 122 is used to provide solenoid valve assembly during the assembly process of the thermal management integrated module 200.

[0050] As an optional implementation manner, the first assembly unit 12 further includes a battery cooler assembly module 123, a heat exchanger assembly module 124, and a first wire harness assembly module 125.

[0051] Among them, the battery cooler assembly module 123 is used to provide battery cooler 27 assembly during the assembly process of the thermal management integrated module 200, the heat exchanger assembly module 124 is used to provide heat exchanger assembly during the assembly process of the thermal management integrated module 200, and the first wire harness assembly module 125 is used to provide first wire harness assembly during the assembly process of the thermal management integrated module 200. Among them, the heat exchanger assembly module 124 includes an ACC (gas-liquid separator) circuit heat exchanger 25 and an LCC (waste heat recovery unit) circuit heat exchanger 26 for assembly.

[0052] As an alternative implementation, the first assembly unit 12 further includes a first pressure sensor 24 assembly module.

[0053] As an alternative implementation, the assembly sequence of each component in the refrigerant-side components by the first assembly unit 12 can be arranged according to actual requirements, so that the most efficient assembly sequence can be selected.

[0054] As an alternative implementation, in the embodiment of the present application, the thermal management integration module 200 includes a refrigerant side. The refrigerant side includes mounting holes for an expansion valve, a solenoid valve, a battery cooler 27, a heat exchanger, a pressure sensor 24, and a first wire harness.

[0055] As an alternative implementation, the expansion valve assembly module 121 is located at the starting end of the first assembly unit 12 and is used to install the expansion valve in the expansion valve mounting hole. The first pressure sensor 24 assembly module is located downstream of the expansion valve assembly module 121 and is used to install the pressure sensor 24 in the pressure sensor 24 mounting hole. The solenoid valve assembly module 122 is located downstream of the first pressure sensor 24 assembly module and is used to install the solenoid valve in the solenoid valve mounting hole. The battery cooler assembly module 123 is located downstream of the solenoid valve assembly module 122 and is used to install the battery cooler 27 in the battery cooler 27 mounting hole. The heat exchanger assembly module 124 is located downstream of the battery cooler assembly module 123 and is used to install the ACC circuit heat exchanger 25 and the LCC circuit heat exchanger 26 in the heat exchanger mounting holes respectively.

[0056] As Figure 3 shown, as an alternative implementation, the test module 131 provided in the embodiment of the present application includes: a solenoid valve control device 1311, an expansion valve control device 1312, a ventilation device 1313, a leak detection device 1314, and a flow rate detection device 1315.

[0057] Among them, when the first test unit 13 performs a product qualification test on the refrigerant-side components of the thermal management integration module 200, the solenoid valve control device 1311 is connected to the solenoid valve in the thermal management integration module 200 and is used to control the solenoid valve. The expansion valve control device 1312 is connected to the expansion valve in the thermal management integration module 200 and is used to control the expansion valve. The ventilation device 1313 is connected to the thermal management integration module 200 and is used to introduce test gas into the thermal management integration module 200. The leak detection device 1314 is connected to the thermal management integration module 200 and is used to test whether the thermal management integration module 200 leaks. The flow rate detection device 1315 is connected to the thermal management integration module 200 and is used to obtain the flow rate of the test gas.

[0058] As an alternative implementation, in the intelligent production line 100 of the thermal management integration module provided by the embodiments of the present application, the test module 131 further includes a storage module 1317, and the storage module 1317 is used to store test programs.

[0059] As an alternative implementation, in the intelligent production line 100 of the thermal management integration module provided by the embodiments of the present application, the test module 131 further includes a control module 1316, which is used to obtain a test program from the storage module 1317 and control the solenoid valve control device 1311, the expansion valve control device 1312, the ventilation device 1313, the leak detection device 1314, and the flow detection device 1315.

[0060] As an alternative implementation, when using the test module 131 provided by the embodiments of the present application, if there is only one valve in a certain pipeline of the refrigerant-side component, the solenoid valve control device 1311 or the expansion valve control device 1312 can be used to close the valve, and ventilation can be performed through the pipeline on one side of the valve. The leak detection device 1314 is used to detect the air pressure change in the pipeline within a period of time after ventilation, so as to judge the sealing performance of the valve.

[0061] Secondly, if there are at least two valves in a certain pipeline of the refrigerant-side component, for the sake of convenience of description, in the present application, based on the direction of ventilation into the pipeline during testing, the valve that the gas in the pipeline reaches first is used as the pre-stage valve, and the valve that the gas reaches later is used as the sub-stage valve, which can also be called the post-stage valve.

[0062] For the case where there are at least two valves in a certain pipeline of the refrigerant-side component, the above-mentioned test method for the case where there is only one valve in the pipeline can be used for reference. First, the leak detection device 1314 is used to test the pre-stage valve in the pipeline. If it is determined that the sealing performance of the pre-stage valve is qualified, the pre-stage valve is opened, ventilation is performed into the pipeline, and the leak detection device 1314 is used to test the sealing performance of the post-stage valve in the pipeline. By analogy, the sealing performance of each valve in the refrigerant-side component can be tested.

[0063] To more specifically illustrate the usage method of the test module 131 provided by the embodiments of the present application, the following will describe its test process in combination with specific refrigerant-side components.

[0064] The refrigerant-side component can be assembled by using the first assembly part 12 provided by the embodiments of the present application. Specifically, such as Figure 4As shown, it shows a schematic structural diagram of the refrigerant-side components of the thermal management integration module 200 provided in the embodiments of the present application. For any thermal management integration module 200, its refrigerant-side components include multiple ports. Outside the thermal management integration module 200, each port is respectively connected to the pipes of the external refrigeration circuit, and the on-off of each port is controlled by a valve; inside the thermal management integration module 200, each port cooperates with each other to form different circuits, and the refrigerant circulates in each circuit, thereby realizing some functions of the thermal management integration module 200.

[0065] As Figure 4 shown, as an optional implementation manner, the refrigerant-side components of the thermal management integration module 200 provided in the embodiments of the present application include a first port 211, a second port 212, a third port 213, a fourth port 214, a fifth port 215, and a sixth port 216. Each port is connected by an internal pipe of the thermal management integration module 200 to form a circuit. Among them, the first port 211 and the second port 212 are connected to form a first circuit, the first port 211 and the third port 213 are connected to form a second circuit, the first port 211 and the fourth port 214 are connected to form a third circuit, and the first port 211 and the fifth port 215 are connected to form a fourth circuit. Except at the first port 211, the third circuit and the fourth circuit are also connected by a pipe, so that the fourth port 214 can communicate with the fifth port 215. For the convenience of description, the pipe connecting the third circuit and the fourth circuit is called the first pipe. In addition, the first port 211 and the sixth port 216 are connected to form a fifth circuit, and the sixth port 216 is also connected to the fifth port 215 to form a sixth circuit.

[0066] According to the above description, the general circuit structure of the refrigerant-side components of the thermal management integration module 200 provided in the embodiments of the present application can be known. In each circuit structure, an expansion valve and / or a solenoid valve are respectively provided to control the on-off of the circuit.

[0067] As an optional implementation manner, in the embodiments of the present application, the refrigerant-side components further include a first solenoid valve 221, a first expansion valve 231, a second expansion valve 232, a third expansion valve 233, a fourth expansion valve 234, a fifth expansion valve 235, and a sixth expansion valve 236.

[0068] As an optional implementation manner, in the embodiments of the present application, a fourth expansion valve 234 is provided at the second port 212 to control the on-off of the first circuit. A third expansion valve 233 is provided at the third port 213 to control the on-off of the second circuit.

[0069] As an alternative implementation, in the third circuit, a first solenoid valve 221 is provided near the fourth port 214, and a second expansion valve 232 is provided near the first port 211. The first solenoid valve 221 and the second expansion valve 232 cooperate with each other to control the on / off of the third circuit.

[0070] As an alternative implementation, in the fourth circuit, a fifth expansion valve 235 is provided near the fifth port 215, and a first expansion valve 231 is provided near the first port 211.

[0071] In the embodiment of the present application, the first expansion valve 231 is also located in the fifth circuit, that is, the first end of the first expansion valve 231 is connected to the first port 211, and the second end of the first expansion valve 231 is connected to the sixth port 216.

[0072] As an alternative implementation, in the sixth circuit, a fifth expansion valve 235 is provided near the fifth port 215, and a sixth expansion valve 236 is provided near the sixth port 216. Specifically, in the fourth circuit and the sixth circuit, these two circuits share the fifth expansion valve 235 and the sixth expansion valve 236, that is, the fifth expansion valve 235 can only affect the on / off states of the fourth circuit and the sixth circuit, and the sixth expansion valve 236 can only affect the on / off states of the fourth circuit and the sixth circuit.

[0073] As an alternative implementation, in the embodiment of the present application, the first end of the first pipeline is connected to the third circuit, and the connection point is located between the first solenoid valve 221 and the second expansion valve 232. The second end of the first pipeline is connected to the fourth circuit, and the connection point is located between the fifth expansion valve 235 and the sixth expansion valve 236.

[0074] According to the above description, the internal pipeline connection state of the refrigerant-side components of the thermal management integration module 200 produced by the intelligent production line 100 of the thermal management integration module provided in the embodiment of the present application can be known. The first test unit 13 provided in the embodiment of the present application performs a product qualification test on the refrigerant-side components of the thermal management integration module 200.

[0075] As an alternative implementation, in the embodiment of the present application, when the test module 131 detects the refrigerant-side components, it first uses the leak detection device 1314 to detect the valves at the previous stage, and then uses the leak detection device 1314 to detect the valves at the subsequent stage.

[0076] For example, taking the first solenoid valve 221 as the previous stage, closing the first solenoid valve 221, ventilating the refrigerant-side components through the fourth port 214, and detecting the air pressure change in the pipeline section from the fourth port 214 to the first solenoid valve 221 within a certain time after ventilation, so as to judge whether the sealing performance of the first solenoid valve 221 is qualified.

[0077] In addition, the fifth expansion valve 235 can be used as the pre-stage. Close the fifth expansion valve 235, ventilate the refrigerant-side components through the fifth port 215, and detect the air pressure change in the pipeline section from the fifth port 215 to the fifth expansion valve 235 within a certain period of time after ventilation, so as to determine whether the sealing performance of the fifth expansion valve 235 is qualified.

[0078] After the sealing performance of the first solenoid valve 221 and the fifth expansion valve 235 is detected, the post-stage valves of the fifth expansion valve 235 can be tested. For the fifth expansion valve 235, since the third circuit is connected to the fourth circuit through the first pipeline, therefore, through the first pipeline, the second expansion valve 232 can be used as the post-stage of the fifth expansion valve 235, and the first solenoid valve 221 can also be used as the post-stage of the fifth expansion valve 235 (since the sealing performance of the first solenoid valve 221 has been detected when it was used as the pre-stage, the sealing performance of the first solenoid valve 221 is not detected here). In addition, in the sixth circuit, the sixth expansion valve 236 can be used as the post-stage of the fifth expansion valve 235.

[0079] Detect the second expansion valve 232 and the sixth expansion valve 236 used as the post-stage. Open the fifth expansion valve 235, ventilate the refrigerant-side components through the fifth port 215, and detect the air pressure change in the pipeline section from the fifth port 215 to the second expansion valve 232 and the sixth expansion valve 236 within a certain period of time after ventilation, so as to determine whether the sealing performance of the second expansion valve 232 and the sixth expansion valve 236 is qualified.

[0080] As an optional implementation method, in order to further determine which one of the second expansion valve 232 and the sixth expansion valve 236 has unqualified sealing performance, the gas pressures at the sixth port 216 and the first port 211 can be detected respectively by the leak detection device 1314. If the pressure at the sixth port 216 exceeds the preset pressure threshold, it is determined that the sealing performance of the sixth expansion valve 236 is unqualified. Similarly, if the pressure at the first port 211 exceeds the preset pressure threshold, it is determined that the sealing performance of the first expansion valve 231 is unqualified.

[0081] According to the above description, the test module 131 provided in the embodiment of the present application has detected the first solenoid valve 221, the second expansion valve 232, the fifth expansion valve 235, and the sixth expansion valve 236 in the refrigerant-side components. Next, the remaining first expansion valve 231, third expansion valve 233, and fourth expansion valve 234 are detected.

[0082] As an alternative implementation, the first expansion valve 231, the third expansion valve 233, and the fourth expansion valve 234 can be closed, and the refrigerant side components can be ventilated from the first port 211, so as to detect the first expansion valve 231, the third expansion valve 233, and the fourth expansion valve 234 simultaneously, improving the detection efficiency. Detect the air pressure change at the first port 211 within a certain period of time after ventilation. If the air pressure change is within the preset range, the sealing performance of the first expansion valve 231, the third expansion valve 233, and the fourth expansion valve 234 is qualified. If the air pressure change exceeds the preset range, at least one of the first expansion valve 231, the third expansion valve 233, and the fourth expansion valve 234 is unqualified. For further identification, the air pressures at the second port 212, the third port 213, and the sixth port 216 are detected respectively. When the pressure at the second port 212 exceeds the set range, the fourth expansion valve 234 leaks. When the pressure at the third port 213 exceeds the set range, the third expansion valve 233 leaks. When the pressure at the sixth port 216 exceeds the set range, the first expansion valve 231 leaks.

[0083] As an alternative implementation, the test module 131 can also test the internal flow rate of the refrigerant side components.

[0084] As Figure 5 shown, it shows a schematic diagram of the ventilation device 1313 provided by the embodiment of the present application. The ventilation device 1313 includes an inlet end and an outlet end. One side of the inlet end is connected to a gas source, and the other side of the inlet end is connected to a first gas path and a second gas path.

[0085] Among them, the first gas path sequentially includes a high-pressure valve 1313a and a stop valve 1313c, the second gas path sequentially includes a low-pressure valve 1313b and a stop valve 1313c, and the first gas path and the second gas path are in parallel; one side of the outlet end is connected to a third gas path and a fourth gas path. The third gas path includes a stop valve 1313c, and the fourth gas path sequentially includes a stop valve 1313c and a flowmeter 1313d. The third gas path and the fourth gas path are in parallel.

[0086] Specifically, both the high-pressure valve 1313a and the low-pressure valve 1313b can be used to adjust the gas flow rate of the ventilation device 1313. The difference is that the gas flow rate adjustment range of the high-pressure valve 1313a is higher than that of the low-pressure valve 1313b. Therefore, through the mutual cooperation of the high-pressure valve 1313a and the low-pressure valve 1313b, precise control of the gas flow rate of the ventilation device 1313 can be achieved.

[0087] As an alternative implementation, in the embodiments of the present application, a pressure sensor 241313e is further provided between the inlet end of the ventilation device 1313 and the gas source. Specifically, in the first gas path, a pressure sensor 241313e is further provided between the high-pressure valve 1313a and the stop valve 1313c. In the second gas path, a pressure sensor 241313e is further provided between the low-pressure valve 1313b and the stop valve 1313c.

[0088] As an alternative implementation, when using the test module 131 provided in the embodiments of the present application to perform a flow rate test on the refrigerant-side components, the flow rates in each loop of the refrigerant-side components are obtained, and the flow rates are compared with the set flow rate range to determine whether the flow rates in each loop are normal.

[0089] Specifically, in the embodiments of the present application, the following steps are required to perform a flow rate test on the refrigerant-side components:

[0090] First, close all valves (including solenoid valves and expansion valves) in the refrigerant-side components;

[0091] The outlet end of the ventilation device 1313 in the test module 131 is connected to the first port 211, and a fixed amount of gas is introduced into the refrigerant-side components from the first port 211.

[0092] Open the first expansion valve 231, use the flow rate detection device 1315 to detect and record the gas flow rate in the fifth loop, and close the first expansion valve 231 after the recording is completed.

[0093] Open the third expansion valve 233, use the flow rate detection device 1315 to detect and record the gas flow rate in the second loop, and close the third expansion valve 233 after the recording is completed.

[0094] Open the fourth expansion valve 234, use the flow rate detection device 1315 to detect and record the gas flow rate in the first loop, and close the fourth expansion valve 234 after the recording is completed.

[0095] Open the second expansion valve 232 and the first solenoid valve 221, use the flow rate detection device 1315 to detect and record the gas flow rate in the third loop, and close the second expansion valve 232 after the recording is completed.

[0096] Disconnect the outlet end of the ventilation device 1313 from the first port 211, and connect the outlet end to the fourth port 214. Introduce a fixed amount of gas into the refrigerant-side components from the fourth port 214.

[0097] Open the fifth expansion valve 235, use the flow rate detection device 1315 to detect and record the flow rate of the loop from the fourth port 214 to the first solenoid valve 221 and then to the fifth expansion valve 235, and close the fifth expansion valve 235 after the recording is completed.

[0098] Open the sixth expansion valve 236, and use the flow detection device 1315 to detect and record the flow rate of the circuit from the fourth port 214 to the sixth expansion valve 236 and then to the sixth port 216.

[0099] Compare the recorded flow rate with the flow rate setting range to determine whether the flow rate in each circuit is normal.
