The heat exchanger plays an important role in chemical industry, petroleum industry, power industry, food industry and other industrial production, can be used as a heater, a cooler, a condenser, an evaporator, a reboiler and the like in chemical industry production, and is widely applied. For example, the polytetrafluoroethylene heat exchanger for low temperature of a power plant is a novel device for recovering waste heat of the power plant for reducing the temperature of exhaust smoke. The fluoroplastic heat exchanger can prevent acid corrosion and reduce the temperature of the flue gas to be within 100 ℃. The expansion-limiting pressure-applying heating welding process for the polytetrafluoroethylene tube plate is developed successfully by Zhengzhou industrial university, and the key technology for connecting the fluoroplastic tube and the tube plate is solved. Subsequently, various types of heat exchangers made in China are put into practical production and application in sequence, and good effects are achieved.

At present, the inside filtering structure for filtering fluid is not arranged in most of heat exchangers in industrial production, and when particles in the fluid are seriously accumulated, the inside of a heat exchange tube is blocked, so that the normal use of the whole heat exchanger is influenced.
