Problems solved by technology

[0002] With the popularization of green energy, people's travel tends to be green energy, and the passenger car is also developing from the original fuel passenger car to the electric passenger car. The electric passenger car is powered by a fuel cell, and the fuel cell is fixed in the battery box. The quality of the battery directly affects the normal operation of the battery. Since the battery box is exposed to the atmosphere all year round, it is greatly affected by the external environment. At the same time, the battery will generate a lot of heat during use. The thermal conductivity of the battery box affects the service life of the battery. Since the battery box is exposed to the outside, high temperature and low temperature have a great impact on the battery work

Embodiment 1

[0022] An insulated pure electric passenger car fuel cell box with temperature regulation performance, including a box body, which is made of silicon carbide composite material;

[0023] The preparation process of the box body is as follows:

[0024] (1) Mix silicon carbide and dextrin according to a certain ratio. The amount of dextrin is 30% of the mass of silicon carbide. Then add ethanol solvent to grind. After the grinding is uniform, it is dried in an oven at 40 ℃, and then at 1400 ℃. Sintering at a temperature of, to obtain macroporous silicon carbide;

[0025] (2) Take the silicon powder and the macroporous silicon carbide prepared in step 1 and put them in a high-speed mixer at a mass ratio of 1:5.3, and then add water, a binding agent and an anti-precipitation agent to the mixer. The binding agent is a phenolic resin. The ratio of the added amount of the agent to the added amount of silicon powder is 1:2.3, high-speed stirring for 2 hours to obtain the mixture, then the mi...

Abstract

The invention discloses an insulated pure electric passenger car fuel cell box with temperature adjustment performance, which includes a box body, the box body is made of a silicon carbide composite material, and the preparation process is as follows: the silicon carbide and a porogen are mixed uniformly according to a certain ratio, Then add ethanol solvent for grinding, grind evenly, dry, and sinter to obtain macroporous silicon carbide; take silicon powder, macroporous silicon carbide, water, binder and anti-precipitation agent, stir at high speed to obtain a mixed material, and then place the mixed material in Press molding in the mold, dry the green body, and then carry out nitriding sintering in the nitriding chamber to obtain a box with a rough surface; the box is soaked in liquid paraffin, then the box is taken out to cool and polished, and finally the surface of the box is Spray a coat of paint. The battery case of the present invention is prepared from a silicon carbide composite material and has a certain strength. At the same time, because the surface of the case body is dipped with liquid paraffin, and the surface of the case body is coated with a layer of paint, the prepared battery case has good temperature and temperature. thermal conductivity.
