回路热管工作温度的控制方式

对比传统直热管,回路热管具有启动迅速、传输距离远、热量大、温差小等优势,但在实际应用中,如在航天器热控、电子元器件散热等场合,又会对回路热管工作温度的精确控制能力又提出新要求。对此要求,文章主要介绍几种目前已经使用以及研发中的回路热管工作温度的主动控制方式,并且比较了它们各自的优缺点。

Active Control of the Operation Temperature in a Loop Heat Pipe

Compared with the conventional heat pipe,the loop heat pipe is a robust heat transfer device and it can transport heavy heat load over a long distance with a small temperature diffe-rence.However,in some practical situations,such as thermal control of spacecraft and heat dissipation of the electronic devices,new requirements are expected to precisely control temperature of the LHPs.In order to realize these requirements,this article mainly introduces several temperature control ways of the LHPs which are used in the labs or the relative fields,and analyzes their advantages and disadvantages.
