摘要 

针对目前物理、材料等领域对于高低温连续可控、可调温度环境的原位测试需求,以 G-M制冷机为冷源,设计了一种被动式可变热阻结构,本结构在低温下具有较高导热系数、高温下具有较低导热系数,可以实现样品温度在 6.2~800 K 大温区范围内可控、可调,且不会对 G-M 制冷机正常运行造成影响。本系统结构简单、运行稳定可靠,且高低温模拟和试验验证结果吻合较好。

Abstract: 

In response to the current demand for in-situ tesling in the fields of physies and materials for acontinuously controllable and adjustable temperature environment at both high and low temperatures, a passivevariable thermal resistanee strueture was designed with a G -M eryocooler as the cold source.This structure hasa high thermal conduetivity at low temperatures and a low thermal conduetivity at high temperatures, enablingthe sample temperature to be controlled and adjusted within a wide range of 6.2 .. 800 K without affecting thenormal operation of the G -M eryocooler,The system is simple in structure, stable and reliable in operation, andthe simulation and experimental verifieation results at both high and low temperatures are in good agreement.

Key words:  GM refrigerator    variable thermal resistance    wide temperature range    high and low temperature
