[0031] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solution of the present invention, rather than limitations thereof.

[0032] like Figure 1 - Figure 6 As shown, this embodiment provides a performance and durability testing device for automotive thermal management valves based on mechanical sensors, including a media frame 100, an environmental chamber 102 fixedly mounted on the media frame 100, and further including:

[0033] The positioning structure 200 is fixedly installed inside the environmental chamber 102. The positioning structure 200 is used to connect the test piece and the mechanical sensor fixedly installed on the positioning structure 200, which is used to detect the contact pressure between the automotive thermal management valve under test and the positioning structure 200 and the sealing force inside the automotive thermal management valve in real time.

[0034] In addition, the circulation structure 300 is fixedly disposed on the medium frame 100 and located below the environmental chamber 102. The circulation structure 300 is used to provide circulating medium to the positioning structure 200.

[0035] By setting up mechanical sensors, data on the extrusion force and sealing force of automotive thermal management valves are collected under medium circulation test conditions.

[0036] Mechanical sensors, including but not limited to pressure sensors, enable the joint performance and durability testing of automotive thermal management valves by transmitting the detected data to the logic control unit of the environmental chamber 102.

[0037] The media frame 100 provides a rigid load-bearing benchmark for the entire equipment, ensuring the installation accuracy and operational stability of each assembled component, avoiding structural deformation, pipeline displacement and other problems during long-term testing, and ensuring the accuracy of test data.

[0038] The positioning structure 200 is fixedly assembled inside the environmental chamber 102 and is specifically used to achieve the positioning, precise clamping, and fluid interface docking of the automotive thermal management valve under test. The circulation structure 300 is fixedly assembled inside the medium frame 100 and is correspondingly arranged directly below the environmental chamber 102. It is connected and cooperates with all the fluid pipelines of the positioning structure 200 to continuously deliver stable and controllable circulating test medium to the valve under test clamped and fixed inside the positioning structure 200. It provides medium circulation support for the performance testing and long-term durability life testing of automotive thermal management valves throughout the process.

[0039] Specifically, the positioning structure 200 includes several return liquid pipes 201 fixedly installed on the environmental chamber 102, and several inlet liquid pipes 202 fixedly installed on the environmental chamber 102 and located below the return liquid pipes 201. One end of each return liquid pipe 201 is fixedly equipped with a return liquid distributor 203, and one end of each inlet liquid pipe 202 is fixedly equipped with an inlet liquid distributor 205. A second connecting pipe 2021 is fixedly installed on the inlet liquid pipe 202, an inlet ball valve 2022 is fixedly installed on the second connecting pipe 2021, and an inlet connector 2023 is fixedly installed at the end of the second connecting pipe 2021. A pump inlet pipe 304 is fixedly installed on the pump supply pump 301, a tank 306 is fixedly installed on the pump inlet pipe 304, and a return flow pipe 305 is fixedly installed on the tank 306. A proportional valve 207 is fixedly installed on the return pipe 201, and a pneumatic ball valve 206 and a mass flow meter 208 are fixedly installed on the inlet pipe 202.

[0040] The positioning structure 200 is a multi-pipeline integrated docking fixture structure, consisting of multiple sets of parallel and independently controllable return liquid pipes 201 and inlet liquid pipes 202. All return liquid pipes 201 and inlet liquid pipes 202 are rigidly fixed and assembled inside the environmental chamber 102. The pipeline layout is neat and the positional accuracy is controllable, ensuring the stability of media transportation from a structural perspective.

[0041] The overall pipeline adopts a layered layout structure. All return pipes 201 are uniformly arranged in the upper area, and all inlet pipes 202 are arranged in the area directly below the return pipes 201. The layered layout can effectively avoid pipeline interference and media crossflow problems, while facilitating pipeline disassembly, maintenance and commissioning.

[0042] Each return liquid pipe 201 is fixedly connected to the return liquid distribution pipe 203 at the same end. All return liquid pipes 201 are connected to the return liquid distribution pipe 203, and the return liquid distribution pipe 203 realizes the centralized collection and unified transportation of multiple branch return media.

[0043] It should be noted that the same end of each liquid inlet pipe 202 is fixedly connected to the liquid inlet distribution pipe 205. The liquid inlet distribution pipe 205 realizes the uniform and precise distribution of the total medium to each liquid inlet pipe 202, thereby forming a multi-pipeline layout structure with centralized distribution, independent liquid supply, and centralized return. It can adapt to the testing needs of automotive thermal management valves with different interface specifications and different numbers of interfaces.

[0044] For each independent liquid inlet pipeline, a dedicated second connecting pipe 2021, a liquid inlet ball valve 2022, and a liquid inlet connector 2023 are provided. The second connecting pipe 2021 is fixedly connected to the medium output end of the liquid inlet pipeline 202. The liquid inlet ball valve 2022 is fixedly installed in the middle of the pipe section of the second connecting pipe 2021, which can independently control the on / off state of a single liquid inlet pipeline and realize the independent start and stop of the medium supply of a single pipeline. The liquid inlet connector 2023 is fixedly installed at the end of the second connecting pipe 2021 away from the liquid inlet pipeline 202. The liquid inlet connector 2023 adopts a structural design that is compatible with the standard interface of automotive thermal management valves, and can achieve a sealed connection with the fluid input interface of the valve under test.

[0045] It should be noted that each return pipeline is equipped with a dedicated first connecting pipe 2011, a return ball valve 2012, and a return connector 2013. The first connecting pipe 2011 is fixedly connected to the medium input end of the return pipeline 201. The return ball valve 2012 independently controls the on / off state of a single return pipeline. The return connector 2013 at the end of the first connecting pipe 2011 is used to connect to the fluid output interface of the receiving valve to ensure the sealing integrity of the medium circulation loop.

[0046] A pneumatic ball valve 206 and a mass flow meter 208 are integrated into the inlet pipe 202. The pneumatic ball valve 206 can realize the rapid on / off switching of the pipeline, adapt to the dynamic start and stop requirements of the test conditions, and has a fast response speed and high control accuracy. The mass flow meter 208 collects the medium flow rate of a single inlet pipe in real time and monitors the stability of the medium supply flow rate throughout the process, ensuring that the test conditions parameters are accurate and controllable.

[0047] It is worth noting that a proportional valve 207 is fixedly installed on the return pipeline 201. The proportional valve 207 can precisely adjust the medium flow pressure and flow opening of a single return pipeline, so as to realize the fine control of the return medium pressure and flow rate, and meet the performance test and durability test requirements of the valve under different working conditions.

[0048] It is worth noting that the entire set of testing fixtures is integrated within the environmental chamber 102, which can simultaneously and reliably perform routine performance testing and long-term durability life testing of valve components. Both types of tests can be completed continuously on the same equipment and under the same clamping condition. This completely solves the defects of traditional equipment, such as fragmented hardware, low reusability of testing equipment, high equipment investment costs, large testing errors caused by multiple disassemblies and reassemblies, and poor test continuity. It greatly simplifies the testing process, improves testing efficiency and accuracy, and effectively reduces equipment procurement and maintenance costs.

[0049] Furthermore, the circulation structure 300 includes a pump outlet pipe 302 fixedly mounted on the inlet and outlet pipe 205, a supply pump 301 fixedly mounted on the pump outlet pipe 302, and a return pipe 305 fixedly mounted on the inlet and outlet pipe 205. A transmission pipe 307 is fixedly mounted on the return pipe 201, a first heat exchange pump 310 is fixedly mounted on the transmission pipe 307, a first circular pipe 309 is fixedly mounted on the first heat exchange pump 310, and a first plate heat exchanger 312 is fixedly mounted on the first circular pipe 309. A third circular pipe 313 is fixedly mounted on the tank body 306, and the third circular pipe 313 is fixedly mounted on the first plate heat exchanger 312. A guide pipe 314 is fixedly mounted on the tank body 306, a second heat exchange pump 316 is fixedly mounted on the guide pipe 314, a second circular pipe 31a is fixedly mounted on the second heat exchange pump 316, and a cooling circular pipe 31b is fixedly mounted on the second circular pipe 31a. A fourth circular pipe 318 is fixedly installed on the tank body 306. A second heat exchanger 308 is fixedly installed on the fourth circular pipe 318 and is fixedly installed on the cooling circular pipe 31b. A first through pipe 319 is fixedly installed on the fourth circular pipe 318. A second through pipe 320 is fixedly installed on the cooling circular pipe 31b and a third heat exchanger 317 is fixedly installed on the second through pipe 320.

[0050] The circulation structure 300 undertakes the functions of medium transportation, medium collection and medium temperature regulation. The liquid supply pump 301 is connected to the liquid inlet distribution pipe 205 through the pump outlet pipe 302. The pressure medium output by the liquid supply pump 301 is transported to the liquid inlet distribution pipe 205 through the pump outlet pipe 302. The liquid inlet distribution pipe 205 distributes the medium to each liquid inlet pipe 202 to provide test medium for the valve under test.

[0051] It should be noted that after the medium flowing out of the valve under test is collected in the return liquid distribution pipe 203, the medium is introduced into the transmission pipe 307. The transmission pipe 307 transports the return medium to the first heat exchange pump 310. The first heat exchange pump 310 drives the medium to be sent into the first plate heat exchanger 312 along the first circular pipe 309. The tank 306 leads out the third circular pipe 313 and connects to the first plate heat exchanger 312. The medium in the tank 306 can enter the interior of the first plate heat exchanger 312 through the third circular pipe 313. The return medium and the incoming medium in the tank 306 complete heat exchange inside the first plate heat exchanger 312 to achieve primary temperature regulation of the medium. After the heat exchange is completed, the medium flows back into the tank 306 and is collected.

[0052] Tank 306 also has a guide pipe 314 leading out, which is connected to the second heat pump 316. The second heat pump 316 drives the medium in tank 306 to be transported to the cooling pipe 31b via the second circular pipe 31a. Tank 306 has a fourth circular pipe 318 leading out and connected to the second heat exchanger 308. The cooling pipe 31b is also connected to the second heat exchanger 308. The medium undergoes secondary heat exchange inside the second heat exchanger 308. A first through pipe 319 is connected to the fourth circular pipe 318, and a second through pipe 320 is connected to the cooling pipe 31b. The second through pipe 320 is connected to the third heat exchanger 317, where the medium can undergo a second stage of heat exchange and adjustment.

[0053] One end of the return pipe 305 is connected to the tank body 306, and the other end is connected to the liquid inlet and distributor pipe 205. When the pressure of the medium inside the pipeline exceeds the set operating conditions, part of the medium flows back to the tank body 306 through the return pipe 305 to achieve medium pressure relief and return.

[0054] Meanwhile, a third heat exchanger 317 is set up to form an additional heat exchange branch. The medium enters the third heat exchanger 317 through the second pipe 320, completes heat exchange, and then returns to the tank 306. Multiple heat exchange branches work together to continuously regulate the temperature of the test medium stored in the tank 306. After temperature regulation, the medium is pressurized and output by the liquid supply pump 301 to continuously supply the valve to be tested in the positioning structure 200, thereby forming a closed-loop medium circulation to continuously provide circulating medium that meets the temperature and pressure conditions for the test.
