Abstract

The invention discloses a single-channel multilayer coil pipe type phase change heat storage device which comprises a heat preservation shell, a heat exchange fluid outlet header, a heat exchange fluid inlet header and N layers of heat exchange coil pipes. The heat preservation shell is a hollow cylinder with an opening in the top. The heat exchange fluid outlet header is arranged on one side of the top of the heat preservation shell. The heat exchange fluid inlet header is arranged on the other side of the top of the heat preservation shell, and the heat exchange fluid inlet header and the heat exchange fluid outlet header are located at the same horizontal position. The heat exchange coil pipes are arranged in an annular array with the center of the heat preservation shell as the center. The problem that due to an existing single-layer coil pipe, temperature distribution in a heat storage device is extremely uneven is solved.

Description

technical field [0001] The invention belongs to the technical field of heat storage, and in particular relates to a single-channel multilayer coil type phase change heat storage device. Background technique [0002] Heat storage technology can effectively solve the problem of time and quantity mismatch between the energy consumption end and the energy supply end. At present, the heat storage technologies that have been commercially applied are mainly sensible heat storage and phase change storage. Among them, phase change heat storage has the advantages of high heat storage density and stable heating temperature, and is considered to be one of the most promising energy storage technologies at this stage. The phase change heat storage device is a key component of the heat storage system. The common forms of heat exchange tubes for heat storage devices are array straight tube type and spiral coil type. Among them, the spiral coil tube is a compact heat exchange tube, and the f...
