Disturbance mixing rapid heat storage module

Abstract

The invention relates to a disturbance mixing rapid heat storage module which comprises a central columnar steam cavity, branch rod steam cavities, axial fan blade type fins, radial fan blade type fins and a phase change container. The central columnar steam cavity is arranged in the phase change container and is connected with the phase change container through a framework rotatable support. The branch rod steam cavities communicate with the interior of the central columnar steam cavity, and are symmetrically distributed along the radial direction of the central columnar steam cavity. The axial fan blade type fins and the radial fan blade type fins are each of an eccentric fan blade structure composed of a plurality of blade cavity ribs different in size and are in clearance fit with the outer surface of the center columnar steam cavity and the outer surfaces of the branch rod steam cavities respectively. Under the action of external impact or disturbance, due to center-of-gravity shift, working media in the phase change container can be promoted to be mixed in the axial direction and the radial direction respectively. The central columnar steam cavity, a plurality of groups of axial fan blade type fins and a plurality of groups of radial fan blade type fins are arranged in the phase change container, and other parts of the phase change container are filled with phase change working media with heat absorption and heat release functions.

Description

technical field [0001] The invention relates to the technical field of rapid heat storage, in particular to a system requiring efficient heat storage or heat dissipation and cooling. Background technique [0002] There are three main types of existing heat storage technologies, including sensible heat storage, latent heat storage, and chemical reaction heat storage. Among them, the latent heat storage system has the characteristics of high energy storage density and small temperature change, and has been successfully applied in solar heat utilization, wind energy storage, industrial waste heat recovery, building energy saving, and heat dissipation of electronic equipment. However, the low thermal conductivity of phase change materials used in latent heat storage systems can severely impair the rate of thermal energy storage and release. Therefore, many researchers use finned tubes and encapsulated phase change materials to increase the heat transfer area, such as shell and ...
