[0025] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0026] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0027] It should be understood that when an element (such as a layer, film, region, or substrate) is described as being "on" another element, the element may be directly on the other element, or there may be intermediate elements. Moreover, in the specification and claims, when an element is described as being "connected" to another element, the element may be "directly connected" to the other element, or "connected" to the other element through a third element.

[0028] As introduced in the background technology, the prior art operates a water pump at a low speed to discharge the gas in the cooling system through the exhaust holes to the expansion water tank, and then discharges it from the expansion water tank. However, there is a problem of low water addition and degassing efficiency. In order to solve the problem that the prior art operates a water pump at a low speed to discharge the gas in the cooling system through the exhaust holes to the expansion water tank, and then discharges it from the expansion water tank, there is a problem of low water addition and degassing efficiency, the present application proposes a fuel cell cooling exhaust system and a vehicle.

[0029] When the fuel cell cooling and exhaust system is refilled and replaced with coolant, the internal structure of the entire cooling system is relatively complex. For example, a large number of bubbles are mixed in the fins of the water side flow channel of the radiator and the cooling flow channel of the stack. The traditional exhaust method is to run the water pump at a low speed, and the gas is discharged through the exhaust holes in the cooling system. The disadvantage is that part of the gas will be discharged, and part of the gas will be sucked into the pump under the suction of the water pump. The impeller of the water pump will break the gas into dense small bubbles, which are adsorbed on the surface of the cooling system, increasing the difficulty of exhaust.

[0030] The utility model proposes a fuel cell cooling exhaust system, such as Figure 1 As shown, the fuel cell cooling exhaust system includes:

[0031] The exhaust circuit includes an expansion water tank 10, and the expansion water tank 10 has a built-in anti-foaming member 11, and the anti-foaming member 11 is used to eliminate bubbles in the cooling system and bubbles in the coolant entering the expansion water tank 10;

The three-way valve 20 and the switch valve 30 are respectively located on the first cooling circuit and the second cooling circuit. During the process of injecting coolant into the expansion water tank 10, the three-way valve 20 is adjusted to make the first cooling circuit conductive and the second cooling circuit closed. After the expansion water tank 10 is filled with coolant, the three-way valve 20 is adjusted to make the first cooling circuit closed and the second cooling circuit conductive. After the coolant fills the second cooling circuit, the three-way valve 20 is adjusted to make the first cooling circuit conductive and the second cooling circuit closed. The switch valve 30 is controlled to be closed, and the coolant flows into the exhaust circuit, so that the bubbles in the coolant are eliminated by using the anti-foaming member 11.

[0033] Specifically, the fuel cell cooling and exhaust system includes a first cooling circuit, a second cooling circuit and an exhaust circuit; wherein, the process of adding water and exhausting air in the fuel cell cooling and exhaust system includes: first, injecting coolant into the expansion water tank; during the process of injecting coolant, adjusting the three-way valve to make the first cooling circuit conductive and the second cooling circuit closed; when the expansion water tank is filled with coolant and the liquid level of the expansion water tank does not drop, determining that the first cooling circuit is filled with coolant; then adjusting the three-way valve to make the first cooling circuit closed and the second cooling circuit conductive; and then operating the water pump at a low speed for a preset time period (for example: 1min, 1.5min) to determine that the second cooling circuit is filled with coolant; adjusting the three-way valve to make the first cooling circuit conductive and the second cooling circuit closed; and then controlling the switch valve to close, and the coolant flows into the exhaust circuit, and the coolant passes through the anti-foaming part in the expansion water tank to eliminate bubbles in the cooling system and bubbles in the coolant entering the expansion water tank, thereby solving the problem of low water addition and degassing efficiency in the prior art.

[0037] In an alternative approach, Figure 3 As shown, the anti-bubble piece 11 divides the interior of the expansion water tank 10 into an exhaust water return area and a water supply area, wherein one side of the anti-bubble piece 11 is a flat mesh plate and the other side is a plurality of arranged bent plates, the flat mesh plate is close to the exhaust water return area, the bent plate is close to the water supply area, and the bottom of the exhaust water return area is connected to the bottom of the water supply area.

[0038] Among them, the anti-foaming structure is as follows Figure 4 and Figure 5 As shown, one side is a plane grid plate 110, wherein the grid can be a square grid, a rectangular grid, or a triangular grid, and the other side is a plurality of bent plates 111 arranged equidistantly in a horizontal direction, and the bending angle of the bent plate 111 can be 60°, 90°, or 120°. The coolant passes through the plane grid plate 110 for preliminary bubble elimination, and the coolant is filtered out of bubbles at the bent plate 111 for secondary bubble removal, and at the same time, it can be ensured that bubbles are generated again when the coolant enters the expansion tank at a high speed and collides with the inner wall and flows back.

[0039] In an optional solution, the bottom of the water supply area of ​​the expansion water tank is lower than the bottom of the exhaust gas return area.

[0040] like Figure 3 and Figure 5 As shown, the bottom of the expansion water tank water supply area is lower than the bottom of the exhaust gas return area.

[0041] The position of the anti-foaming member 11 inside the expansion tank is as follows: Figure 3 shown.

[0048] When the fuel cell cooling and exhaust system works normally, the coolant flows in the first cooling circuit; when the expansion water tank is filled with coolant, the filling level of the expansion water tank does not drop, the three-way valve is controlled to close the first cooling circuit, the second cooling circuit is turned on, and the water pump is operated at low speed for 1 minute to ensure that the pipeline connected to the three-way ball valve is full of coolant, then the switch valve is closed, the three-way valve is controlled to turn on the first cooling circuit, and the second cooling circuit is closed. At this time, the coolant flows in the exhaust circuit (water pump, three-way valve, radiator, particle filter, battery stack, expansion water tank, water pump), and the bubbles in the cooling system are completely discharged to the expansion water tank through the exhaust port and the return port. The bubbles are eliminated under the action of the defoaming parts of the expansion water tank, and the bubble-free coolant of the fuel cell cooling and exhaust system is replenished through the water replenishment port of the expansion water tank.
