Heat conductive plastic heat exchange module used for countercurrent closed cooling tower

Abstract

The invention relates to a heat conductive plastic heat exchange module used for countercurrent closed cooling tower, which includes upper and lower headers as well as a module frame, wherein the upper and the lower headers are fixed on the module frame respectively, a layer of heat conductive plastic tubule grate is formed by hot melting two ends of multiple heat conductive plastic thin tubes on the upper and the lower headers respectively, separation strips are arranged among the thin tubes to reserve intervals, the middle part of the tubule grate is fixedly connected to fixing plates on two sides through support rods respectively, and a tension device is mounted between each fixing plate and the module frame so as to balance the deformation of the heat conductive plastic thin tubes selves in the length direction caused by temperature and tension. The heat conductive plastic heat exchange module can provide a larger heat exchange area in a limited space, and has excellent freezing resistance and corrosion resistance; the tension devices can keep the thin tubes straight, reduce the circulation resistance inside the thin tubes, and improve the uniformity of water sprinkle; the thermal performance of the closed tower equipped with the heat exchange module can be improved, and the application scope of the heat conductive plastic heat exchange module can be widened; in addition, the manufacture cost of the heat conductive plastic thin tube is far lower than that of the metal tubes, so that the construction cost of the closed tower can be lowered due to the adoption of the heat conductive plastic heat exchange module.

Description

technical field [0001] The invention relates to a cooler or a core component of a cooling tower, in particular to a heat conduction and heat exchange module of a counterflow closed cooling tower. Background technique [0002] Closed cooling towers are widely used in cooling industrial circulating working fluids to discharge waste heat to the air, and are closely related to energy and water conservation that urgently need to be solved in national economic and social development. [0003] A chiller that cools circulating water with air is often called a cooling tower. The heat transfer in the coil is restricted by the cooling water and there is spray water outside the tube to assist in heat dissipation, which is called a closed cooling tower. When the cooling fluid in the tube is other than water, it is often called an evaporative cooler, and the phase change of the working fluid in the cooling process is called an evaporative condenser. Different names, but the principle an...

AI Technical Summary

Problems solved by technology

There are many problems: 1. In cold areas, when the cooling tower is shut down, the accumulated water in the coil is not easy to drain, and the coil is easy to freeze and crack

2. The metal pipe is not resistant to corrosion, and it is easy to leak when it needs to cool the working fluid containing corrosive substances; 3. The surface of the metal pipe is easy to scale, and the long-term accumulation of dirt will affect the heat exchange efficiency of the closed tower; 4. The production of metal pipes from All links from materials to products have high energy consumption and are expensive
