High-low temperature in-situ spectrum reaction tank

Abstract

The invention discloses a high-low temperature in-situ spectrum reaction tank, and relates to the technical field of spectrum reaction tanks. The spectrum reaction tank comprises a base, an optical window, a sample table, a refrigeration unit, a heating unit, a ventilation unit and an electrical test unit. A groove is formed in the top wall of the base, and the optical window covers the groove toform a sealed cavity. The sample table is located in the groove, and a cavity is formed in the sample table. The spectrum reaction tank has the following beneficial effects: the reaction tank realizescontrol of high and low temperature environment fields in a small system through a simple structural layout, so the temperature can reach a change interval from the lowest 4K extremely low temperature to 300 DEG C above zero, and line layouts of various gases and liquids are greatly reduced at the same time; and meanwhile, in a limited space size, the reaction tank is also loaded with an electrode pressing sheet and an SMA connector which can be used for carrying out electrical testing on a wiring component under a variable-temperature condition, so that the electrical testing requirements athigh and low temperatures are met.

Description

technical field [0001] The invention relates to the technical field of spectral reaction cells, in particular to a high-low temperature in-situ spectral reaction cell. Background technique [0002] As an important physical property change parameter, temperature parameter will affect various properties of materials in many ways. In fact, the behavior of materials will change greatly from ambient temperature to low temperature. Therefore, from the perspective of general engineering, it is necessary to study the changes in the electrical, thermal, mechanical and magnetic properties of pure metals, alloys and insulators caused by changes in temperature parameters. The mechanism is very meaningful. The properties of materials are generally subject to specific physical equations, so that these physical equations can be used to predict the behavior of the system. They depend on chemical composition, crystal structure, atomic and charge interactions, thermal or mechanical treatmen...
