Abstract
Embodiments of the present invention include a connection pipe and a method of manufacturing the connection pipe for an evaporator of a refrigeration device. In the connection pipe and method, high-frequency welding is performed while a first pipe is at one side of a tube and a second pipe is at another side of the tube are welded, and a first curvature portion is in the first pipe and a second curvature portion is in the second pipe. Even though the connection pipe according to embodiments of the present invention is forced or pressed to connect a suction pipe to the second pipe, the connection pipe may not be deformed or damaged due to a structural characteristic during installation of the evaporator in the refrigeration device.
Claims5
A method of a connection pipe for an evaporator of a refrigeration device, comprising:
- inserting a first pipe having a first end and a second end and a second pipe having a third end and a fourth end into a tube to physically connect the first pipe and the second pipe, wherein the first pipe and the second pipe are substantially straight;
- forming a first curvature portion in the first pipe and forming a second curvature portion in the second pipe;
- and
- coupling an end of the second pipe to a suction pipe,
- wherein the first and second curvature portions are formed after coupling the first pipe and the second pipe,
- wherein the first curvature portion has a first curvature angle wherein the first end and the second end of the first pipe are configured to form an acute angle,
- wherein the second curvature portion has a second curvature angle, wherein the third end and the fourth end of the second pipe are configured to form an obtuse angle,
- wherein the first curvature portion and the second curvature portion have curvature directions that are opposite to each other, and
- wherein the first pipe comprises aluminum and the second pipe comprises copper.
