Abstract

The invention discloses a temperature control device for material low-temperature surface characteristic research. The temperature control device is composed of a semiconductor refrigeration system, acold circulation system and a refrigeration sheet control system, wherein the semiconductor refrigeration system is divided into two stages, and is composed of a first-stage semiconductor refrigeration system and a second-stage semiconductor refrigeration system; the cold circulation system consists of a first-stage cold circulation system and a second-stage cold circulation system; and the refrigeration piece control system is composed of a temperature sensor and a mainboard. The temperature control device has the advantages of being small in size, low in power, low in cost, and therefore simple to implement; and a low-temperature environment can be created conveniently by only a power supply, and a low-temperature condition can be provided for a laboratory without an environment-controllable atomic force microscope.

Description

technical field [0001] The invention belongs to the technical field of low-temperature surface characteristics research, and relates to a temperature control device for creating a low-temperature environment for the research of low-temperature surface characteristics of materials such as graphene. Background technique [0002] Graphene is a new type of functional material, which has broad application prospects in the field of friction and wear. However, the friction characteristics of graphene at low temperature are still unclear, the main reason is the lack of suitable high-precision, high-reliability low-temperature environment experimental equipment. [0003] At present, the construction of astronomical telescopes under extreme low temperature conditions such as the Antarctic has become a technical competition point for various countries. The construction of astronomical telescopes has put forward requirements for the development of high-precision micro-displacement actua...
