Abstract (en)
The present invention pertains to a heat exchanger pipe and a manufacturing method thereof, wherein heat exchange is carried out between fluid which flows along the inside of a pipe and fluid which exists outside the pipe. In particular, the flow of the fluid flowing in the pipe becomes more active and the amount of contact is increased so as to improve heat exchange efficiency. Furthermore, the manufacturing of the heat exchanger pipe is simple while the contact characteristics and sealing characteristics between an outer pipe and an object to be inserted into the inside of the outer pipe are improved.
