Abstract Common heat exchangers can not meet the demands of some special areas, such as wastewater treatment of chemical industry, acid and alkali salt circulation equipment. Therefore, there is a great value of the application of plastic heat exchanger and it has been greatly developed in recent years. In order to improve the overall efficiency of heat exchanger and the maximum service temperature of the plastic heat exchanger, graphite is used as filler and the FEP was mollified with it. In this paper, we make the hollow fiber by composite material with small diameter, thin wall and good thermal conductivity. And the heat exchangers were made by the heat conductive hollow fibers. This paper mainly discussed the formula of the composite material and the influences of preparation process on hollow fibers’ mechanism and thermal properties. Testing of “water to water” heat exchanging was made by self-made conductive hollow fiber heat exchanger to study the influence and regularity of the heat exchanger performance by changing the fluid process and flux. The result shows that the heat exchangers made by FEP with graphite composite has low cost, light weight, easy installation and transporting. They have thermal conductive material high fill rate per unit volume and great heat exchange performance.
