Xinfei refrigerator, Beijing Xinfei refrigerator after-sales service telephone repair case; Method for plugging leaks in evaporators with leakage holes.
Fault phenomenon: The refrigerator evaporator has a leakage hole.
Analysis and maintenance: The evaporator of a home refrigerator is mostly made of aluminum, which is extremely prone to corrosion and small leakage holes. In the event of this fault, use a drill bit to drill the leakage hole into a round hole, then process an aluminum wire into a metal patch slightly smaller than the diameter of the round hole, with a thickness the same as that of the aluminum piece of the evaporator. Then apply epoxy resin glue liquid to the round hole and the aluminum patch, and embed the patch into the round hole. After two days, it will be firmly bonded (to ensure reliable bonding, the fit between the patch and the round hole should be as tight as possible).
