[0073] For example, the water pump interface 31, electric heater interface 32, water filter interface 33, deionizer interface 34, and thermostat interface 35 are all detachable chuck interfaces, each with a different size. This facilitates flexible installation and disassembly, and each device interface has reserved positions for different sized interfaces, making it convenient for testing devices with different models or sizes of interfaces.

[0081] For example, the input end of the water pump interface 31 is the same as in the above embodiment. The output end of the water pump interface 31 is provided with a second temperature sensor 57 and a second pressure sensor 56. The water pump interface 31 is used to connect a water pump. The deionizer interface 34 is located between the water pump interface 31 and the electric heater interface 32.

[0083] In this embodiment, the water pump, deionizer, and electric heater can be tested simultaneously.

[0084] In one embodiment, such as Figure 1 As shown, the control module also includes a pressurization unit, a vacuum unit, and a water replenishment unit electrically connected to the water replenishment tank; the acquisition module also includes a liquid level monitoring unit, the pressurization unit is used to adjust the pressure inside the water replenishment tank; the vacuum unit is used to evacuate the water replenishment tank, the water replenishment unit is used to replenish the water replenishment tank with liquid medium, and the liquid level monitoring unit is used to monitor the liquid level of the liquid medium in the water replenishment tank.

[0085] For example, such as Figure 1 As shown, the control module 4 also includes a pressurization unit 42, a vacuum unit 43, a water replenishment unit 44, a one-way valve 45, and a safety valve 46, all electrically connected to the water replenishment tank 1.

The liquid level sensor works in conjunction with the water replenishment manual valve 441 and the water replenishment solenoid valve 442 to monitor the liquid level in the water replenishment tank 1 and automatically replenish the liquid. The one-way valve 45 prevents backflow of the liquid medium, and the safety valve 46 provides overpressure protection to prevent excessive pressure in the circulation loop.

[0086] In one embodiment, such as Figure 1 As shown, the pressurization unit includes, in sequence, a gas source interface connected to the pipeline, a pressurization manual valve, a pressure regulating valve, and a pressure relief valve. The gas medium is introduced through the gas source interface, and the inlet pressure of the water supply tank is adjusted through the pressurization manual valve. The liquid level pressure in the water supply tank is adjusted through the pressure regulating valve and the pressure relief valve.

[0087] For example, the pressurization unit 42 includes, in sequence, a gas source interface 421 connected by a pipeline, a pressurization manual valve 422, a pressure regulating valve 423, and a pressure relief valve 424. A gas medium is introduced through the gas source interface 421, and the inlet pressure of the water supply tank 1 is adjusted through the pressurization manual valve 422. The liquid level pressure in the water supply tank 1 is adjusted through the pressure regulating valve 423 and the pressure relief valve 424.

[0088] Before the test begins, the first solenoid valve 41 and the fourth solenoid valve 412 are in the closed state. The fuel cell system cooling road equipment test apparatus is as follows: Figure 1 The five interfaces shown are water pump interface 31, deionizer interface 34, thermostat interface 25, electric heater interface 32, and water filter interface 33. All are detachable chuck-type interfaces, and each chuck-type interface has a different size. After the device under test (DUT) is connected, the first solenoid valve 41 and the fourth solenoid valve 412 are in the open state to ensure the continuity of the circulation loop. After the test is completed, the first solenoid valve 41 and the fourth solenoid valve 412 are closed before the DUT is removed. The water in the water supply tank 1 and the water storage tank 2 can be continuously recycled. The water in the DUT pipeline is drained through the interface drain valve 410 to facilitate the removal of the DUT.

[0089] The pressure in the pipeline is adjusted as needed by the combination of the pressure boosting valve 422, the pressure regulating valve 423, and the pressure relief valve 424, and the flow rate in the pipeline is adjusted by the pump speed. Vacuuming by the vacuum pump 431 allows for testing of the pump's net positive suction head (NPSH), and understanding the pump's performance limits is crucial for its safe operation. By collecting flow rate data within the circulation loop using a flow meter, and by using pressure and temperature sensors at the pump's input and output terminals, differential pressure and temperature data can be obtained, enabling tests on various pump performance parameters such as flow rate-head, flow rate-power, and flow rate-efficiency.

[0090] With zero added sodium chloride (NaCl), start the water pump and adjust the flow rate to the first test flow rate. Record stable inlet / outlet conductivity values. The outlet conductivity should be very low at this point, indicating the deionizer is operating optimally. Gradually add a fixed volume of NaCl powder to water tank 1 or other ionic solutions in a gradient. After the NaCl dissolves, continuously monitor the solution conductivity. Adjust the flow rate in the pipeline by controlling the pump speed to test the deionizer's adsorption capacity. By collecting the flow rate within the circulation loop using a flow meter, various performance tests of the deionizer, such as flow resistance and adsorption capacity, can be performed.

[0091] By adjusting the flow rate of the pipeline through the pump speed, collecting the flow rate in the circulation loop through the flow meter, and controlling the opening degree through the duty cycle of the thermostat, various performance tests such as thermostat flow resistance, flow distribution, and power consumption can be achieved.

[0092] By adjusting the flow rate of the pipeline through the pump speed, collecting the flow rate in the circulation loop through the flow meter, and controlling the temperature through the electric heater or PTC, various performance tests such as the flow resistance, heating power, and efficiency of the electric heater can be performed.

[0093] By adjusting the flow rate of the pipeline through the pump speed, collecting the flow rate in the circulation loop through the flow meter, and collecting the pressure difference through the pressure sensor, various performance tests such as water filter flow resistance and filtration capacity can be achieved.

[0094] The above describes the test items that this device can perform on various components, including but not limited to the performance items listed above.
