与其他形式的传热相比,热管传热具有许多优点,其主要表现如下:1.传热能力大。由于热是利用潜热传热,所以,它的传热能力很大。它的传热能力比导热性能最好的金属银还可以高成千上万倍。2.等温传递——两端温差极小。因为热管内工质的蒸发和冷凝是在大致相同的温度下进行的,吸热和散热是通过在相同的温度下工质发生相变而吸收和交出潜热来完成的。热源温度的变化仅仅影响蒸发速度和热平衡温度,对其温差影响很小。例如一根直径为一英寸
Compared with other forms of heat transfer, heat pipe heat transfer has many advantages, its main performance is as follows: 1. Heat transfer capacity. Because heat is the use of latent heat transfer, so its heat transfer capability. It’s heat transfer ability than the best thermal conductivity of silver can be thousands of times higher. 2. Isothermal transfer - minimum temperature difference between ends. Since the evaporation and condensation of the working fluid in the heat pipe are performed at approximately the same temperature, the heat absorption and heat dissipation are achieved by absorbing and expelling the latent heat by phase change of the working fluid at the same temperature. Changes in heat source temperature only affect the evaporation rate and heat balance temperature, the temperature difference has little effect. For example, a diameter of one inch
