Solid-liquid phase change material solidification heat transfer performance parameter testing device and method thereof

The invention discloses a solid-liquid phase change material solidification heat transfer performance parameter testing device and a method thereof. The device comprises a phase change material container, a liquid phase material feed port, a glass tube, a heating rod, an analog-digital converter, and a computer. The phase change material container cavity contains a solid-liquid phase change material, the liquid phase material feed port is inserted to a position above the symcenter of the phase change material container, the liquid phase material feed port is in connection with the glass tube, the heating rod is inserted into the glass tube, and the heating temperature keeps consistent with the initial temperature, the liquid level analog signal of a liquid level sensor is transmitted into the analog-digital converter in real time, and the digital signal deduced by the analog-digital converter is transmitted to the computer. According to the invention, based on the volume shrinkage data in a solid-liquid phase
