Self-oscillating high-efficiency heat exchange tube

The utility model relates to a heat exchange tube in a heat exchanger, in particular to a self-oscillating high-efficiency heat exchange tube for reinforcing heat exchange. In the utility model, the cross section of the heat exchange tube is ring-shaped, the whole heat exchange tube is spring-shaped, and the tube material of the heat exchange tube requires high toughness. The lead angle of a part with a heat exchange function is 10-30 degrees, and the thread pitch is 3-6 times as much as the external diameter. After the heat exchange tube is installed in the heat exchanger, the pressure and the flow velocity of medium (such as hot water and the like) flowing through the heat exchange tube are constantly changed in various ways, so that the heat exchange tube can self oscillate, thereby realizing the heat transfer in small space and large heat amount. The heat transfer efficiency is increased, and tube wall scaling can be effectively prevented. Compared with the traditional heat exchange tube, the self-oscilla
