Problems solved by technology

[0004] The present invention provides a fuel cell cooling plate for new energy vehicles, which has the beneficial effect of uniform cooling, and solves the problem that the cooling water of the existing fuel cell cooling plate mentioned in the background technology is usually drawn from the cooling plate when it is working. One end enters at a low position, and then flows out from the other end of the cooling plate at a high position. During this process, there will be a temperature difference between the two ends of the cooling plate, which will cause the problem of uneven reaction

Embodiment 1

[0027] see Figure 1-Figure 5 , a fuel cell cooling plate for new energy vehicles, comprising a plate body 1, the inside of the plate body 1 is provided with a cavity, and the lower end of the plate body 1 is provided with a first cooling water inlet 2, and the upper end of the plate body 1 is provided with a cooling The water outlet 3, the first cooling tank 4, the second cooling tank 5 and the third cooling tank 6 are arranged in the cavity, one end of the third cooling tank 6 communicates with the cooling water outlet 3, and the upper end of the plate body 1 is provided with a second Cooling water inlet 7, and the second cooling water inlet 7 communicates with the second cooling tank 5, one end of the first cooling tank 4 communicates with the first cooling water inlet 2, and between the first cooling tank 4 and the second cooling tank 5 A water hole 401 is provided, a hole sealing assembly is provided in the first cooling tank 4, a first outlet 601 for communicating with t...

Embodiment 2

[0034] see Figure 4 and Figure 5 , in this embodiment, the technical solution is basically the same as that of Embodiment 1, the only difference is that the hole sealing assembly includes a first piston 8 and a second piston 9, and one end of the first piston 8 is connected to the plate body through the first elastic connector 10 1 Elastic connection, the other end of the first piston 8 is provided with a connecting plate 11, the end of the connecting plate 11 away from the first piston 8 is provided with a limiting plate 12, the second piston 9 is inserted into the water hole 401, and the second piston One end of the piston 9 is elastically connected to the second cooling groove 5 through the second elastic connecting piece 13 , and the other end of the second piston 9 abuts against the limiting plate 12 .

[0035] Different from Embodiment 1, the lower end of the second piston 9 in this technical solution does not have a limiting protrusion, and a limiting plate 12 is pro...

Embodiment 3

[0037] see image 3 , this embodiment is a further improvement on Embodiment 1, the end of the limiting block 14 close to the second piston 9 is provided with a slope, and the limiting block 14 is provided with several notches 1401 . The upper end of the limit block 14 is provided with a slope, the existence of the slope makes the limit block 14 move upwards when the second piston 9 is moved, because the limit block 14 will hinder the cooling water in the first cooling tank 4 Therefore, several notches 1401 are opened on the limit block 14 to facilitate the flow of cooling water.

Abstract

The invention relates to the technical field of fuel cell cooling plates for new energy vehicles, and discloses a fuel cell cooling plate for new energy vehicles, including a plate body, a cavity is provided inside the plate body, and a There is a first cooling water inlet, the upper end of the plate body is provided with a cooling water outlet, the cavity is provided with a first cooling groove, a second cooling groove and a third cooling groove, and one end of the third cooling groove is connected to the The cooling water outlet is connected, and the upper end of the plate body is provided with a second cooling water inlet. In this technical solution, three cooling grooves are arranged in the plate body. The first cooling groove, the second cooling groove and the third cooling groove together form a rectangle. Between the first cooling groove, the second cooling groove and the third cooling groove, the high temperature The water area and the low-temperature water area are all corresponding to each other, and can exchange heat and neutralize each other, so that when the entire cooling plate is working, the temperature difference between each area is small, and the cooling effect is better.

Description

technical field [0001] The invention relates to the technical field of fuel cell cooling plates for new energy vehicles, in particular to a fuel cell cooling plate for new energy vehicles. Background technique [0002] A fuel cell is an energy conversion device, which isothermally converts the chemical energy stored in the fuel and oxidant directly into electrical energy according to the electrochemical principle, that is, the working principle of the primary battery, so the actual process is an oxidation-reduction reaction. A fuel cell is mainly composed of four parts: the anode, the cathode, the electrolyte and the external circuit. Fuel gas and oxidant gas are passed through the anode and cathode of the fuel cell respectively. The fuel gas emits electrons on the anode, and the electrons are conducted to the cathode through an external circuit and combine with the oxidizing gas to form ions. Under the action of an electric field, the ions migrate to the anode through the...
