Abstract

The present invention provides an interface thermal resistance control method, which is used to control the thermal resistance at the thermal interface formed by the close contact between the first thermal pole and the second thermal pole, the first thermal pole is made of metal material, and the second thermal pole is made of metal material. The two thermal poles are made of non-metallic materials; the thermal resistance at the thermal interface is adjusted by changing the electric field intensity at the thermal interface. The method provided by the invention realizes thermal rectification simply and effectively, and provides possibility for further manufacturing various thermal logic devices.

Description

technical field [0001] The invention relates to the field of thermal technology, in particular to a method for regulating and controlling interface thermal resistance. Background technique [0002] When heat flows through the interface of two contacting solids, the interface itself presents an obvious thermal resistance to heat flow, that is, interfacial thermal resistance. Thermal logic control can be realized by adjusting the size of the interface thermal resistance, and thermal devices can be manufactured on this basis. However, in the prior art, there is no method for effectively controlling the thermal interface resistance and a thermal device with adjustable interface thermal resistance. Contents of the invention [0003] In view of this, it is indeed necessary to provide a method for controlling the interface thermal resistance to overcome the deficiencies in the prior art. [0004] A method for controlling interface thermal resistance, which is used to control th...
