Problems solved by technology

However, there is a problem with this structure that if there is any difference between the outer diameter of the capillary tube 10 and the inner diameter of the other tube 11, or if the welder's inexperience causes poor welding, the two tubes 10 and 11 may cannot be completely welded together, resulting in refrigerant leaks, such as Figure 1b shown
Also, in some cases, the filler metal 12 can flow into another tube 11 and also block the capillary

Abstract

The invention discloses a copper tube connecting apparatus for connecting a copper tube with another tube to facilitate welding operation in the refrigerating device. The new apparatus will reduce the poor welding rate so that it will effectively prevent clogging of the copper tubes and leaking the refrigerant. It also has merit to easily determine a suitable heating time while the copper tubes are welding. Thus, the rate of poor welding is reduced, as well as a method for connecting copper tubes by using the tube connecting apparatus.

Description

technical field [0001] The present invention relates to a device and a method for connecting copper pipes in refrigeration equipment. The present invention also particularly relates to a copper pipe connecting device, which is suitable for connecting one copper pipe to another in a refrigeration device, which can facilitate the welding operation, reduce the welding failure rate, and prevent the copper pipe from being damaged due to poor welding. blockage or leakage of refrigerant through the welding site, and can make the welder easily determine the appropriate welding heating time when the copper pipe is connected to another pipe, thereby reducing the welding defect rate. In addition, the present invention also proposes A method of making copper pipe connections using a pipe connection device. Background technique [0002] As we all know, in the prior art, a refrigeration device has the following refrigeration cycle process: the refrigerant flows through a compressor, a co...
