What are the parts of the refrigerator 5I want more details, thank you!!
3. heat insulation layerIn the past, the thermal insulation of the refrigerator was filled with glass wool, and now the refrigerator insulation is made of polyurethane foam. Polyurethane foam plastics are foamed by adding foaming agent in the polymerization process of isocyanate and polyether.Foaming agents used to use R11, which has a great destructive effect on the ozone layer in the atmosphere. Now the foaming agent gradually changed to R141b or cyclopentane, these two foaming agents are environmentally friendly foaming agent.4. door hingeThe box body and the door body are connected by a door hinge. A single door refrigerator, two door refrigerator has a hinge, and a hinge three. Generally, the door hinge is provided with a limiting mechanism and a self-locking mechanism.
The refrigerator is mainly composed of five parts: the box body, the door, the refrigeration system, the electrical system and the accessories.I. box and door bodyThe box body and the door body are composed of a plurality of chambers according to different temperature requirements, and are isolated from the outside air and are kept at a certain low temperature respectively. The box body and the door body are composed of a box case, a box case, a door shell, a door gall, etc..OneThe shell and door shell are generally made of cold rolled steel sheet of 0.4-0.8mm and treated by phosphating and spray (or spray painting). In order to beauty, the door shell multi-purpose color plate, and some refrigerators have used wire drawing board.2. boxes of bravery, door gall, usually with thick 1.2-5mm ABS board or HIPS board, made by vacuum molding. The box is also made of aluminium plate. The strength of this case is better than that of plastic, but the corrosion resistance is less than that of plastic.
