Embodiment Construction

[0023] In order to better understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings. Such as figure 1 , 2 As shown, a metal mesh-based bellows type phase change heat storage device includes a shell 3 and a heat storage box 5. The heat storage box 5 is divided into multiple layers, and consists of a shell, a heat exchange tube 7, and a fluid distribution tube 11. Composed of fluid collection pipes 8, the corrugated pipes of each layer communicate with the fluid collection pipes 8 through fluid distribution pipes 11, and the corrugated pipes between layers form a tight staggered arrangement in the heat storage box 5, in the same layer The nodes and troughs of two adjacent rows of corrugated pipes correspond to closely staggered rows. At the same time, metal wires 10 are wound between two adjacent rows of corrugated pipes to form a mesh structure to enhance heat transfer. Other vacant places in the heat ...

Abstract

The invention relates to a metal net base corrugate pipe type phase change heat storage device, which comprises an outer housing and a heat storage box body, wherein the heat storage box body is divided into multiple layers and consists of a housing, corrugate pipes, fluid distributing pipes and fluid collecting pipes; the corrugate pipes on each layer are communicated with the fluid collecting pipes through the fluid distributing pipes; the corrugate pipes between layers are placed inside the heat storage box body in a tight and staggered manner; in the same layer, wave nodes and wave troughs in two adjacent rows of the corrugate pipes correspondingly form tight and staggered arrangement; meanwhile, metal wires are twisted in the two adjacent rows of the corrugate pipes to form a net structure so as to strengthen heat transfer, and other spare parts of the heat storage box body are filled with heat storage phase change material. The device is simple in structure and large in heat exchange area, a turbulent flow can be formed when a fluid flows in the corrugate pipes, the heat transfer efficiency is improved, the heat absorption and heat discharge speed is quick, the heat storage material capacity is large, and the heat storage capacity is improved; and the phase change heat storage device can fully utilize solar energy and industrial exhaust heat to carry out high efficiency waste heat recovery utilization.

Description

technical field [0001] The invention relates to a heat storage and heat supply device, in particular to a metal mesh-based bellows type phase-change heat storage device, which belongs to the technical field of heat storage. Background technique [0002] With the continuous development of the economy and the massive consumption of energy, the topic of energy conservation has become the focus of global attention. Nowadays, the utilization of renewable energy such as solar energy, wind energy, and industrial waste heat has become the focus of research in various countries. However, these energy sources have the characteristics of discontinuity and instability. Therefore, the research on energy storage technology is particularly important. Heat storage energy storage technology is a kind of energy storage technology, which can be used to solve the contradiction between thermal energy supply and demand mismatch, and is an important technology to improve energy utilization effici...
