Abstract

The invention discloses an insulating pure-electric bus fuel cell box with a temperature adjusting property. The insulating pure-electric bus fuel cell box with the temperature adjusting property comprises a box body which is prepared from a silicon carbide composite material. A preparation process comprises the following steps: uniformly mixing silicon carbide with a pore-foaming agent accordingto a certain proportion, then adding an ethanol solution, grinding uniformly and drying, and sintering to obtain macroporous silicon carbide; taking silicon powder, the macroporous silicon carbide, water, a binding agent and an antisettling agent, and stirring at high speed to obtain a mixture, pressurizing and forming the mixing in a mold, drying a blank, and carrying out nitridation sintering ina nitridation chamber to obtain a box body with rough surfaces; and soaking the box body in liquid paraffin, taking out the box body, cooling and polishing, and spraying the surfaces of the box bodywith a layer of coating. The cell box is preared from the silicon carbide composite material and has certain strength, and meanwhile, because the surfaces of the box body are dipped with the liquid paraffin and are coated with the coating, the prepared cell box has good temperature regulation and heat conduction properties.

Description

technical field [0001] The invention belongs to the field of passenger cars, and relates to an insulated pure electric passenger car fuel cell box with temperature regulation performance. Background technique [0002] With the popularization of green energy, people's travel also tends to be green energy, and passenger cars have also developed from the original fuel passenger cars to electric passenger cars. Electric passenger cars are powered by fuel cells, in which the fuel cells are fixed in the battery box, and the battery box The quality of the battery directly affects the normal operation of the battery. Because the battery box is exposed to the atmosphere all the year round and is greatly affected by the external environment, and at the same time, a large amount of heat is generated during the use of the battery. The thermal conductivity of the battery box affects the service life of the battery, and Since the battery case is exposed to the outside, high temperature an...
