PURPOSE: A heat exchanger comprising a twist tape is provided to increase the flow rate and the flow speed of the fluid since a twist tape is inserted into a heat transfer pipe, through which the fluid flows. CONSTITUTION: A twist tape(10) is built in a heat transfer pipe of a heat exchanger. The twist tape has a shape, which is formed by twisting a slit coil in a given direction. The fluid flowing in the heat transfer pipe rotates and flows by the twist tape to increase the heat transfer efficiency and to facilitate the cleaning of the heat transfer pipe. The twist tape is divided into straight parts(11) and twisted parts(12), the straight parts are formed on given parts of both ends of a product and the twisted parts are formed between the straight parts. |
