Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0036] See Figure 1-2 The embodiment of the present invention provides an interface thermal resistance control method, which is used to control the thermal resistance at the interface between a metallic material and a non-metallic material. The control method includes:

[0037] Step S11, providing a first thermal pole 10 and a second thermal pole 20, the first thermal pole 10 is made of metal material, the second thermal pole 20 is made of non-metallic material, and the first thermal pole The pole 10 is in close contact with the second hot pole 20 to form a thermal interface 100; and

[0038] Step S12, adjusting the thermal resistance at the thermal interface 100 by changing the intensity (direction and / or strength) of the electric field at the thermal interface 100.

[0039] In step S11, the first hot pole 10 and the second hot pole 20 are both made o...

Abstract

The present invention provides 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 material, and the first thermal pole is made of non-metallic material. A heat pole is in close contact with the second heat pole to form a heat interface; a heat resistance adjustment unit is used to generate a regulating electric field at the heat interface. The thermal triode 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 present invention relates to the field of thermal technology, in particular to a thermal triode. Background technique [0002] When heat flows through the interface of two solids in contact, the interface itself presents a significant thermal resistance to the heat flow, that is, interfacial thermal resistance. Thermal logic control can be achieved by adjusting the size of the interface thermal resistance, and thermal devices can be manufactured on this basis. However, there is no method for effectively controlling the interface thermal resistance and a thermal device with adjustable interface thermal resistance in the prior art. Summary 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 a metal material, the second thermal pole is made of a non-m...
