Embodiment Construction

[0030] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0031] refer to figure 1 , a phase change heat storage and / or cold storage device, including a heat exchange space 1, and a phase change material 2 and a heat exchange fluid 3 are arranged inside the heat exchange space 1, wherein the heat exchange fluid 3 fills the heat exchange space 1, so that the phase The variable material 2 can be completely immersed in the heat exchange fluid 3 . Preferably, the heat exchange fluid 3 and the phase change material 2 are ...

Abstract

The invention belongs to the technical field of heat storage and / or cold storage devices and particularly relates to a phase change heat storage and / or cold storage device. A heat exchange space is included, a phase change material and heat exchange fluid are arranged in the heat exchange space, the heat exchange space is filled with the heat exchange fluid, the phase change material can be completely soaked in the heat exchange fluid, the heat exchange space is filled with the heat exchange fluid, the phase change material can be completely soaked in the heat exchange fluid, the phase changematerial can make direct contact with the heat exchange fluid for heat transfer, and the heat resistance formed by a phase change material sealing layer in the prior art can be effectively avoided. The temperature difference needed by the heat exchange fluid and the phase change material heat transfer is effectively reduced, and the aim of reducing energy storage of the phase change heat storage and / or cold storage device and / or the limit temperature difference during energy releasing can be achieved.

Description

technical field [0001] The invention relates to the technical field of heat storage and / or cold storage equipment, in particular to a phase change heat storage and / or cold storage equipment. Background technique [0002] Phase change heat storage and / or cold storage is a high-tech energy storage technology based on phase change energy storage materials, which are mainly divided into thermochemical heat storage, sensible heat storage and phase change heat storage. Although thermochemical heat storage has a high density of heat storage and / or cold storage, it is unsafe and the process of heat storage and / or cold storage is uncontrollable, which seriously affects its popularization and application. Sensible heat storage is currently the most widely used heat storage method, but its heat storage density is low. The heat storage density of phase change heat storage is 5-10 times or even higher than sensible heat storage, and phase change heat storage and / or cold storage has the ...
