[0017] Figure 1 FIG. 1 is a schematic diagram of the structure of an expansion water tank fixture for bench testing according to an embodiment of the present invention. Figure 1 As shown, an expansion water tank tooling for bench testing according to a preferred embodiment of the present invention includes: a tank body 1, two air inlets 4, a filter screen 7 and a water outlet 2. The two air inlets 4 are respectively opened on both sides of the top of the tank body 1, and the two air inlets 4 are respectively connected to the engine degassing pipe and the radiator degassing pipe. The filter screen 7 is arranged inside the tank body 1. The water outlet 2 is opened at the bottom of the tank body 1, and the water outlet 2 is connected to the water replenishing port of the engine water inlet pipe. Among them, the water vapor inside the engine and the water vapor inside the radiator enter the interior of the tank body 1 through the two air inlets 4 respectively, and the filter screen 7 is used to filter and break the bubbles in the water vapor. Among them, the water vapor passing through the filter screen 7 enters the water replenishing port of the engine water inlet pipe through the water outlet 2.

[0018] In one embodiment of the present invention, the tank body 1 is cylindrical. The expansion water tank tooling for bench testing further includes a liquid level observation tube 3 disposed on one side of the tank body 1 , and the liquid level observation tube 3 is used to observe the liquid level in the tank body 1 .

[0020] In one embodiment of the present invention, the expansion water tank tooling for bench testing further includes a pressure relief valve 6 disposed on the top of the tank body 1. The area of ​​the water outlet 2 is greater than the sum of the areas of the two air inlets 4.

[0021] In practical applications, the working principle of the expansion water tank fixture for bench testing of the present invention is as follows: the two air inlets 4 of the expansion water tank are respectively connected to the engine degassing pipe and the radiator degassing pipe, and the pressure joint of the expansion water tank is connected to the pressure sensor to monitor the pressure of the expansion water tank. The water outlet 2 of the expansion water tank is connected to the water replenishment port of the engine water inlet pipe to realize the automatic water replenishment function of the closed cooling system. The water vapor inside the engine and the water vapor inside the radiator transport the water vapor to the expansion water tank through the degassing port. The filter screen 7 of the expansion water tank filters and breaks the bubbles in the water vapor to achieve the degassing function. The coolant (filtered water vapor) in the expansion water tank continues to circulate to the engine cooling system, thereby ensuring the normal operation of the engine cooling system.
