Abstract
The invention discloses an internal threaded copper tube. The internal threaded copper tube comprises a tube body (1), wherein internal threaded teeth with different height and various tooth shapes are formed on the inner wall of the tube body (1) and are alternately distributed. Due to the difference of the tooth shapes and the height, the turbulent flow intensity of a coolant is increased, and disturbance on the coolant and heat conduction energy efficiency are improved. In the using process, the tooth shapes of the common internal threaded copper tube are damaged while the tube is expanded, and due to the difference of the tooth shapes and the height, only a part of tooth shapes of the internal threaded copper tube are damaged after the internal threaded copper tube is expanded, and the internal threaded copper tube still has high heat transfer efficiency. By using the optimized design, the weight, production cost and using cost of the tube can be reduced. The internal threaded copper tube is suitable to be widely used in the fields of refrigeration, air conditioning, power generation, sugar making, chemical industry, solar energy and the like.
