Abstract

The invention provides a thermionic triode. The thermionic triode comprises a first thermal pole, a second thermal pole and a thermal resistance regulating unit. The first thermal pole is made of a metallic material. The second thermal pole is made of a non-metallic material. The first thermal pole and the second thermal pole make close contact to form a thermal interface. The thermal resistance regulating unit is used for forming a regulation and control electric field at the thermal interface. The thermionic triode provided by the invention is simple in structure, effectively realizes thermal rectification and makes it possible to further manufacture various types of thermal logic devices.

Description

technical field [0001] The invention relates to the technical field of heat, in particular to a thermal triode. 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 thermal triode to overcome the deficiencies in the prior art. [0004] A thermal triode, comprising: a first thermal pole and a second thermal pole, the first thermal pole is made of metal material, the second thermal pole is made of non-metallic mat...
