Description

Technical Field

[0001] The utility model belongs to the technical field of refrigerator evaporators, in particular to a copper tube aluminum fin type evaporator for a refrigerator. Background Art

[0002] A freezer refers to a device that preserves food and other items at low temperatures, and the copper tube aluminum fin evaporator is one of the components of a freezer. The function of the copper tube aluminum fin evaporator in a freezer is to absorb heat and reduce the temperature inside the freezer, thereby achieving the function of refrigeration or freezing;

[0003] Copper tube aluminum fin evaporator refers to a kind of efficient heat exchange equipment. The copper tube aluminum fin evaporator combines the advantages of copper tubes and aluminum fins to achieve excellent heat transfer performance. The design of the copper tube aluminum fin evaporator is based on the good thermal conductivity of copper tubes and the large heat dissipation area of ​​aluminum fins. Through the close combination of copper tubes and aluminum fins, the heat exchange efficiency is effectively improved. The copper tube aluminum fin evaporator is composed of copper tubes, aluminum fins, connectors, protective components, mounting plates and other components.

[0004] However, it still has the following disadvantages in actual use:

[0005] The existing copper tube aluminum fin type evaporator for freezers is provided with aluminum fins on the copper tube, which combines the good thermal conductivity of the copper tube with the large area heat dissipation of the aluminum fins, and is conducive to improving the cooling effect inside the freezer. However, in the process of setting the aluminum fins on the peripheral side wall of the copper tube, it is not convenient to determine the spacing between two adjacent aluminum fins, resulting in uneven spacing between multiple aluminum fins on the copper tube, resulting in uneven cooling effect of the existing copper tube aluminum fin type evaporator for freezers, and reducing the uniformity of cooling inside the freezer;

[0006] 2. The existing copper tube aluminum fin evaporator for freezers is provided with a protective component on the outside of the evaporator core assembly. The protective component is two upper and lower protective frames, which are locked and connected by bolts. The evaporator core assembly includes copper tubes and aluminum fins, and the protective component is locked in the interior of the freezer by bolts to prevent foreign objects from hitting the evaporator core assembly and to provide good dust protection for the evaporator core assembly, which is beneficial to improving the service life of the existing copper tube aluminum fin evaporator for freezers. However, in the process of repairing the evaporator core of the freezer, it is necessary to remove the bolts and remove the entire copper tube aluminum fin evaporator from the freezer. Then, the protective component is disassembled and the copper tube aluminum fin evaporator is taken down for repair, which complicates the entire repair process of the copper tube aluminum fin evaporator and increases the workload of the staff.

[0007] To this end, we provide a copper tube aluminum fin evaporator for a freezer to solve the above problems. Utility Model Content
