Description
Technical Field
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
The existing heat storage technology mainly comprises three types, including sensible heat storage, latent heat storage and chemical reaction heat storage. The latent heat storage system has the characteristics of high energy storage density, small temperature change and the like, and has been successfully applied to the aspects of solar heat utilization, wind energy storage, industrial waste heat recovery, building energy conservation, electronic equipment heat dissipation and the like. However, the low thermal conductivity of the phase change materials used in latent heat storage systems can severely impair the rate of storage and release of thermal energy. Therefore, many researchers have used finned tubes and encapsulated phase change materials to increase heat transfer areas, such as shell-and-tube heat storage systems, microencapsulated phase change materials. Although the finned tube has very high performance enhancement effect on the conventional heat exchanger and is very effective on a latent heat storage system, the conventional fins are of fixed structures, heat transfer is carried out only by means of heat conduction, and the fixed fin structures separate phase-change working media and obstruct the flow of the working media, so that heat is seriously unevenly distributed. In the heat storage stage of the traditional phase change material, due to the difference of density and the action of buoyancy, the solid working medium absorbs heat to be liquid and moves upwards, natural convection is generated in the container, so that the uniformity of the overall temperature of the phase change material can be promoted, but the non-uniformity in the horizontal direction still exists, and the heat release rate in the phase change container is slowed down due to the fact that the natural convection of the phase change working medium or a fixed fin structure cannot be effectively improved, and the efficiency and reusability of the heat storage equipment are seriously influenced. In some specific use conditions, such as national defense, automobiles, oil exploration and other systems, equipment is usually subjected to vibration, impact, swing and other problems, and the process is a representation of mechanical energy, so that the mechanical energy is expected to be utilized in the aspect of enhancing the uniformity of the heat storage process.
According to the fin structure composite heat storage device disclosed in the patent CN212116004U, heat is rapidly conducted to various positions inside by using the cooperation of a plurality of structures such as a heat pipe, fins and the like, so that the rapid storage of the heat is realized. The patent proposes the thinking of heat pipe collocation fin, but metal fin only can pass through heat conduction mode transfer heat for the mounting, and this fin structure is fixed connected mode, only can pass through heat conduction mode transfer heat, does not have the description that relies on mechanical energy reinforcing axial and radial convection heat transfer, is different with this patent structure and design thinking.
The heat exchanger for a heat storage system disclosed in patent CN104718422a increases the heat exchange area between the tube and the phase change material by using two fins extending radially and longitudinally, improving the heat storage efficiency of the phase change material. This patent proposes a radial-like fin type to homogenize the heat of the tube to the space. However, the metal fins provided by the patent are in a fixed connection mode, heat can be transferred only through a heat conduction mode, and no description of enhancing axial and radial convection heat transfer by means of mechanical energy is available, and the metal fins are different from the structure and design thought of the patent.
The heat accumulating type wind power heating machine disclosed in the patent CN101818955A drives the bracket rod to rotate by wind power, and utilizes the stirring blade group on the bracket rod to stir liquid substances, so as to complete the conversion from mechanical energy to heat energy, thereby realizing the function of wind power heating. The patent proposes a stirring vane assembly which allows stirring of the liquid in the vessel and is also a way of enhancing convection. However, this stirring blade group requires continuous external driving, and cannot produce continuous stirring effect by short-time impact or disturbance from the outside, unlike the structure and design concept of this patent.
In the rotary phase change heat accumulator disclosed in patent CN108020107a, forced convection is generated inside the liquid phase change material by using rotary blades, so that the heat exchange efficiency of the liquid phase change material is enhanced. However, this rotary blade requires continuous external driving, and cannot produce continuous stirring effect by short external impact or disturbance, unlike the structure and design concept of this patent.
