THERMAL SWITCH

摘要

The present invention relates to a thermal switch, particularly a thermal switch that improves heat transfer efficiency and allows easy control form opening/closing a thermal connection through heat transfer fluid by supplying heat transfer fluid stored or supplied in a fluid storage channel to a tunnel or a switching channel to allow the heat transfer fluid opened to the upper part of the switching channel to be in surface contact with a panel to transfer heat. The present invention provides thermal switch controlling heat transfer between a heat source and a heat sink, which includes: a main panel; a groove-shaped fluid storage channel formed on the downside of the main panel, and containing or supplied with heat transfer fluid; a tunnel formed on the upside of the main panel, connected with the fluid storage channel, and supplied with the heat transfer fluid from the fluid storage channel; and an air discharge channel formed on the upside of the main panel and connected with the tunnel to form an air passage. Further, the thermal switch controls heat transfer between the heat source and heat sink by adjusting a level of the heat transfer fluid in the tunnel.
