Abstract

A method for assembling a liquid reservoir of an evaporator, which is characterized in that it includes the following steps, S1: performing ultrasonic cleaning on the liquid reservoir to be welded to remove surface oil and rust defects, and drying; S2: installing the first inner lining into the outlet of the reservoir; S3: insert the conduit into the outlet of the reservoir and fix it, and then place it on the welding table to weld the outlet; S4: fix the second lining on the pressing machine, and then Align the inlet of the reservoir in S3 with the second inner lining, so that the second inner lining is inserted into the inlet of the reservoir, and the inlet of the reservoir is shrunk by a pressing machine, so that the second inner lining is fixed on the Inside the inlet of the liquid reservoir; S5: Insert the outlet pipe of the evaporator into the inlet of the liquid reservoir in S4, and then place it on the welding workbench to weld the inlet; S6: Remove the evaporator with the liquid reservoir, and weld it Finish. The invention optimizes the assembly method of the liquid storage device and improves the welding effect.

Description

technical field [0001] The invention relates to the technical field of evaporator assembly, in particular to a method for assembling a liquid reservoir of an evaporator. Background technique [0002] The liquid receiver is a refrigeration accessory used to store the liquid refrigerant and absorb the water in the refrigerant. One end of the liquid receiver is connected to the outlet pipe of the evaporator, and the other end is welded to the pipe. [0003] In the prior art, the two ends of the liquid reservoir are directly welded to the air outlet pipe and the conduit, so that the connection between the liquid reservoir and the pipe fittings is easy to loosen during welding, resulting in an unsatisfactory shape of the welded part, and due to the combination of the above factors Effect, resulting in poor weld quality, affecting the use effect. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a method for assembling ...
