Abstract

The invention discloses a test device for stored/released energy of a shaped phase-change material. The test device comprises a test container, wherein the test container is connected with a signal conditioning module and an industrial controller through a guide wire respectively; an A/D (analog to digital) conversion module is arranged between the signal conditioning module and the industrial controller; the industrial controller is connected with a clock module, a display screen and a keyboard respectively. The test device for stored/released energy of the shaped phase-change material is relatively wide in scope of application, adjustable in size of a to-be-tested sample, capable of meeting research needs of a relatively phase-change material, and suitable for researching and developing a relatively thick material; a temperature distribution condition, in a phase-change process, inside the phase-change energy storage material can be tested to provide experimental data to research the phase-change mechanism; a plurality of test samples can be tested simultaneously; application environment under different conditions can be simulated by regulating the internal temperature and the size of the constant-temperature container. Compared with thermal analysis apparatuses such as a DSC (differential scanning calorimeter) which are millions of yuan in price and the like, the test system disclosed by the invention is low in 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 ...
