Abstract

The invention relates to a hot melt adhesive pipe, a production technology thereof and a technology for adhering a refrigerating pipe to a heat-conductive plate. Ethylene ethylacrylate copolymer materials are adopted, the temperature of an extruding machine is set, a hot melt adhesive pipe is extruded and formed, and after being cooled, the hot melt adhesive pipe is manufactured. The refrigerating pipe is sleeved with the hot melt adhesive pipe, heating is carried out so that the hot melt adhesive pipe can be hot-melted, and the refrigerating pipe is connected with the heat-conductive plate. Hot melt adhesive has an anti-corrosion effect on the surface of the refrigerating pipe. The refrigerating pipe does not need to be oxidized, the production technology is simplified, and energy consumption is reduced. Besides, the adhesion area of the hot melt adhesive and the refrigerating pipe and the adhesive area of the hot melt adhesive and the heat-conductive plate are large, and adhesion is firmer. Adhesion portions are not prone to disengaging in the subsequent foaming treatment process of an evaporator, and the quality of the refrigerator evaporator is improved.

Description

technical field [0001] The invention relates to a production process of an evaporator accessory, in particular to a hot-melt rubber hose used for a refrigerator evaporator and a production process thereof. Background technique [0002] The evaporator is an important part of the refrigerator. Its function is to realize the evaporation, heat absorption and cooling of the refrigerant. The refrigeration tube of the existing evaporator is fixed on the heat conducting plate by hot melt adhesive. When bonding, Use a hot-melt adhesive film to cover the temperature-conducting plate, then place the cooling tube on the hot-melt adhesive film, heat to a certain temperature, make the hot-melt adhesive film melt, and bond the cooling tube and the temperature-conducting plate together. For this kind of evaporator, in order to prevent corrosion, the refrigeration tube needs to be oxidized before being bonded to the temperature conducting plate. In the process of foaming, the cooling tube i...
