Abstract

A testing device for storing / releasing energy of a shaped phase change material disclosed in the present invention comprises a test container, the test container is respectively connected with a signal conditioning module and an industrial computer through wires, and an A / D conversion module is arranged between the signal conditioning module and the industrial computer , the industrial computer is respectively connected with a clock module, a display screen and a keyboard. The storage / release energy testing device for shaped phase change materials of the present invention has a wide range of applications, and the size of the sample to be tested can be large or small, which can meet the research requirements of relatively fine phase change materials, and is also suitable for the research and development of relatively coarse materials. Development; it can measure the temperature distribution inside the phase change energy storage material during the phase change process, and provide experimental data for the study of the phase change mechanism; it can measure multiple samples at the same time; by adjusting the internal temperature and volume of the constant temperature container, it can simulate different The application environment of the case. Compared with thermal analysis instruments such as DSC with a price of several million yuan, the test system proposed by the invention has low cost.

Description

technical field [0001] The invention belongs to the technical field of material testing equipment, and in particular relates to a storage / release energy testing device for shaped phase change materials. Background technique [0002] Existing test devices for measuring phase change materials mainly measure the energy storage capacity of a very small amount of phase change materials, such as DSC differential scanning calorimeter, which consists of heating furnace, sample tray, temperature sensor, signal conditioner, A The / D converter and the computer are connected in sequence. The temperature sensor is used to test the temperature at the bottom of the crucible, the signal conditioner amplifies and converts the analog electrical signal from the temperature sensor, the output signal is transferred to the A / D converter, the analog electrical signal is converted into a digital signal, and input to the computer. The temperature rise and fall curves tested by computer are used to ...
