Abstract

The invention discloses a circular stability testing system of a multichannel solid-liquid phase change material, wherein the testing system comprises a mechanical arm, a testing unit, a data collector, a movement control unit and a computer. The testing system sends a command to a movement controller through the computer and controls the mechanical arm to move up and down and rotate through the movement controller so as to quickly switch a sample container in heat source constant temperature grooves with different temperatures to realize the automation of fusion-solidification of a sample to be tested, and the data collector collects and stores the internal temperature of the sample to be tested through a temperature sensor built in the sample container and displays a temperature-time curve on the computer in real time. The testing system provided by the invention is mainly used for testing the circular stability of the solid-liquid phase change material, and the testing system provided by the invention can be used simultaneously testing multichannel and multiple different types of materials to be tested, thereby greatly improving the testing efficiency of the circular stability of the solid-liquid phase change material.

Description

technical field [0001] The invention relates to a cycle stability test system of a multi-channel solid-liquid phase change material, which belongs to the field of energy-saving and environment-friendly material test equipment. Background technique [0002] A phase change material (PCM, Phase Change Material) will absorb or release a large amount of energy in a narrow temperature range near the phase change point during the phase change process. At present, solid-liquid phase change materials, which have been studied more, have a much higher energy storage density than sensible heat storage materials, and can be used for industrial waste heat recovery, solar thermal energy utilization, cold storage and air conditioning systems, and building temperature control and insulation. [0003] The performance parameters of solid-liquid phase change materials mainly include phase transition point, latent heat of phase transition, and cycle stability, among which the cycle stability tes...
