Abstract
The present invention relates to a heat exchanger pipe enabling heat exchange between fluid flowing through the pipe and fluid existing outside the pipe, and a method of manufacturing the heat exchanger pipe. In particular, the present invention relates to a heat exchanger pipe that improves a heat exchange rate by making flow of fluid through the pipe more active and increasing a contact amount, that has an improved contact characteristic and a sealing characteristic between an outer pipe and an insert inserted in the outer pipe in the process of manufacturing, and that is easily manufactured; and a method of manufacturing the heat exchanger pipe.
