Rapid automatic phase-change material thermal cycle experiment instrument

Abstract

The invention discloses a rapid automatic phase-change material thermal cycle experiment instrument. The instrument comprises a water tank with a cold liquid tank and a hot liquid tank, a first dividing wall arranged inside the cold liquid tank, a second dividing wall arranged inside the hot liquid tank, a motor which is arranged inside the water tank and is isolated from the cold liquid tank and the hot liquid tank, a first sample drawing and loading mechanism driven by the motor, a second sample drawing and loading mechanism driven by the motor, a refrigeration device which is arranged inside the cold liquid tank and is used for refrigerating cold liquid, a heating device which is arranged inside the hot liquid tank and is used for heating hot liquid, and a control module for enabling the instrument to carry out automatic operation. The rapid automatic thermal cycle experimental instrument has the advantages of high energy efficiency, high time effectiveness and capability of accomplishing the rated cycle times with low energy consumption and rapid speed; the heat conduction liquid is constant, precise and controllable in temperature; the instrument is automatically monitored through the process with high automation degree; and the situations that the conventional thermal cycle experiment is manually carried out, low in efficiency, low in precision and poor in repeatability are changed.

Description

technical field [0001] The invention relates to a rapid automatic thermal cycle experiment instrument for phase change materials, in particular to a rapid automatic thermal cycle experimental instrument for phase change materials used in material durability cycle experiments. Background technique [0002] Phase change material is a general term for materials that undergo liquid-gas, solid-gas, solid-liquid or solid-solid phase transitions at operating temperatures. Due to their excellent thermophysical properties, phase change materials have attracted more and more attention in the fields of aerospace, military, construction, clothing, and solar energy. [0003] Not all phase change materials can be used in practical applications. The selection of phase change materials must follow certain rules and requirements, one of which is durability. Phase change materials will undergo volume changes when undergoing a phase change, and some phase change materials will also produce su...

Problems solved by technology

This method takes a long time to experiment, the experiment deviation is large, and the repeatability is not good.

Chinese patent CN102636512A introduces an automatic thermal cycle device, but it adopts the method of circulating hot and cold liquids, and the cycle speed is relatively slow, and devices such as water pumps and valves are used, so the test speed is relatively slow, and the heat transfer liquid is also in the process of continuous circulation. There will be losses, the energy efficiency is not high
