Problems solved by technology

[0002] In household appliances such as air conditioners and refrigerators, copper tubes are generally used at present. The disadvantages are: shortage of copper tube materials, high cost, and heavy weight.
However, galvanized pipes and plastic pipes are commonly used in cold and hot water supply pipes for construction. Galvanized pipes are easy to rust and block, and plastic pipes are easy to age and have a short service life.

Abstract

The present invention relates to a copper-aluminium composite pipe made up by using seamless copper pipe and seamless aluminium pipe. Said composite pipe has two-layer pipe wall structure or three-layer pipe wall structure. Its two-layer structure is characterized by that its outer layer is seamless copper pipe layer and its inner layer is seamless aluminium pipe layer or its outer layer is seamless aluminium pipe layer and its inner layer is seamless copper pipe layer, and its three-layer structure is characterized by that its intermediate layer is seamless aluminium pipe layer and its outer layer and inner layer are seamless copper pipe layer.

Description

technical field [0001] The invention relates to a copper-aluminum composite pipe, which can be widely used in the refrigeration appliance industry, such as pipes in air conditioners and refrigerators, and cold and hot water supply pipes for buildings. Background technique [0002] In household appliances such as air conditioners and refrigerators, copper pipes are generally used at present. The disadvantages are: shortage of copper pipe materials, high cost, and heavy weight. However, galvanized pipes and plastic pipes are commonly used in cold and hot water supply pipes for buildings. Galvanized pipes are prone to corrosion and blockage, while plastic pipes are prone to aging and have a short service life. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the prior art and provide a copper-aluminum composite pipe with high mechanical strength, moderate weight and low cost. ...
