Abstract

The invention discloses a phase change heat storage device and a water heater. The phase change heat storage device comprises a shell, at least two layers of phase change bodies and a heat exchange pipeline; the shell is provided with a containing cavity; the at least two layers of phase change bodies are contained in the containing cavity, and the two adjacent layers of phase change bodies are not mutually miscible; and the difference between the upper-layer phase change temperature point and the lower-layer phase change temperature point of every two adjacent layers of phase change bodies ranges from 5 DEG C to 10 DEG C; and the heat exchange pipeline is arranged in the phase change bodies in penetrating and inserting modes. The phase change heat storage device in the technical scheme can increase the heat exchange speed and improve the heat exchange efficiency.

Description

technical field [0001] The invention relates to the field of heat energy equipment, in particular to a phase change heat storage device and a water heater. Background technique [0002] Water heaters generally have a heat storage function, which stores heat through a heat storage device, so that users can obtain hot water in time when using hot water. There are many types of heat storage devices, and phase change heat storage materials are favored due to their high heat storage density, and the use of phase change materials as heat storage materials has been more and more widely used. [0003] However, although the phase change material of the existing phase change heat storage device has high latent heat, its phase change temperature is single. Release latent heat, the heat transfer speed is not ideal, and the heat transfer efficiency is low. Contents of the invention [0004] The main purpose of the present invention is to provide a phase change heat storage device and...
