Description

一种热管传热装置及空调 技术领域
本发明涉及一种换热设备技术领域，具体涉及一种热管传热装置及空调。
背景技术
热管，是一种利用工质蒸发和冷凝的镶边过程快速传递热量的装置，因其具有传热能力强，是纯铜的数千倍，利用毛细现象或重力驱动，能耗低以及可靠性高的特性，已由之前的宇航、军工等行业迅速扩展应用于散热器制造行业，成为各种空气温度调节装置中传热性能优良的传热元件。
在现有技术中，常规热管在结构布局中因组空结构导致高差受限，从而造成热管中工质的循环动力有限，为了解决循环动力不足的问题，不少厂家不得不采用增加循环泵的方式以提升热管内工质的循环动力，但热管换热装置中的全部工质均采用循环泵来进行增压循环，存在如下缺陷：
1)循环泵的故障会导致热管的完全失效；
2)循环泵体积过大，不仅配置空间困难，影响热管换热装置的整体布局，还会因功率过大，大大增加了设备能耗。
另外，传统热管传热装置的连接管路复杂，蒸发段和冷凝段相对位置不易调整，难以适应不同场景的应用。
因此，本技术领域需要一种管路配置简单、结构紧凑易调整且高效节能的热管传热装置。
发明内容
为了解决上述技术问题，本发明提出了一种管路配置简单、结构紧凑易调整、重力驱动及动力驱动相结合的热管传热装置。
