Description

Technical Field

[0001] The utility model particularly relates to a mounting structure of a refrigerator evaporator. Background Art

[0002] The refrigerator evaporator is a key component in the refrigerator refrigeration system. It is responsible for absorbing internal heat, thereby reducing the temperature inside the refrigerator. The refrigerator evaporator generally includes an evaporation pipe and fins arranged on the pipe to exchange the heat of the refrigerant inside the pipe with the outside. When installing the evaporator inside the refrigerator, it is generally fixed with bolts.

[0003] During the later maintenance of the existing refrigerator evaporator, multiple bolts installed need to be disassembled in order to inspect or replace the evaporator. Multiple bolts need to be loosened during disassembly, and then multiple bolts need to be tightened after the evaporator is replaced. This is troublesome and time-consuming. There is also a risk of bolts being lost during the disassembly process, which makes maintenance inconvenient. For this reason, we propose a mounting structure for a refrigerator evaporator.
