Embodiment Construction

[0027] Embodiments of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art would recognize that the described embodiments can be modified in various ways or combinations thereof without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims. Also, in this specification, the drawings are not drawn to scale, and like reference numerals denote like parts.

[0028] Combine below Figure 1-Figure 6 This embodiment will be described in detail.

[0029] In the heat storage device, the speed of heat storage and thermal diffusion efficiency are two important parameters that characterize the heat storage capacity of the heat storage device. Among them, the speed of thermal diffusion efficiency is related to the heat transfer coefficient and heat transfer efficiency of the heat storage working medium. The s...

Abstract

The invention discloses a heat storage method utilizing foam copper and ferromagnetic fluid. The heat storage method comprises the following steps that a magnetic field is provided to a heat storage main body through a magnetic field supply device, and the ferromagnetic fluid in the heat storage main body flows under the driving action of the magnetic field and a heat source of a heat source utilization device, and heat is stored; and a foam copper framework is further arranged inside the heat storage main body, and the foam copper framework and the ferromagnetic fluid are soaked with each other. Due to the fact that the heat conduction coefficient of the foam copper framework is high, the heat storage rate can be improved; due to the fact that the temperature-sensitive ferromagnetic fluidis sensitive to temperature, the convective heat transfer rate is high, the heat storage rate can be remarkably improved, and the temperature-sensitive ferromagnetic fluid has relatively high specific heat, so that the heat storage capacity can be improved.

Description

technical field [0001] The invention relates to the technical field of new energy and high efficiency and energy saving, in particular to a heat storage method and device using foamed copper and ferrofluid. Background technique [0002] With the improvement of people's living standards, the demand for energy is increasing, but the current utilization rate of energy is not high, neither industrial waste heat nor waste heat in human daily life is well utilized. The heat storage device is a device that adopts an appropriate method and uses a specific device to store temporarily unused or excess heat through a certain heat storage material, and then release it for use when needed. Storing heat through heat storage devices can improve energy utilization, especially the utilization efficiency of some industrial waste heat, which is conducive to the rational use of waste heat and waste heat. [0003] Heat storage devices include sensible heat storage, latent heat storage, and chem...
