Abstract
The utility model discloses a phase changing energy storage ball, which relates to the technical field of the cold storage and the heat storage of phase changing material under lower temperature condition and high temperature condition. The utility model comprises an energy storage casing body, phase changing medium arranged in the energy storage casing, and a through hole foamed metal framework arranged in the phase changing medium. The energy storage casing can adopt material with high intensity, fatigue resistance, high density and good heat-conducting property, such as polyethylene, metal, etc. Through hole foamed metal material with high heat-conducting property, high porosity factor, small density and larger specific surface area is installed in the energy storage casing body, the phase changing medium flows through the through hole on the foamed metal material, the through hole foamed metal material plays the framework function in the phase changing medium, and can rapidly change the internal temperature of the energy storage device to ensure the internal temperature and the external temperature of the energy storage device to be balanced, the phase changing medium can adopt water, eutectic salt, stone natrium or other phase changing mixture, therefore the efficiency of the cold storage and the heat storage is enhanced, the energy storage is further reduced, and the purpose of improving the energy utilization is realized.
Description
Technical field
The utility model relates to phase-change material and store up technical field cold, heat accumulation under the low temperature and the condition of high temperature.
Background technology
Greatly develop along with socioeconomic, more and more higher to the demand of the energy, also rate of energy is had higher requirement simultaneously.Because phase-change material has good energy-storage property in the change process of state, be widely used in industries such as air conditioner refrigerating, utilization of new energy resources and building energy conservations.But present employed Energy storage ball, its inner water that adopts is as phase-change material, and heat conductivility is poor, can not change the internal temperature of Energy storage ball at short notice rapidly and uniformly, causes storage cold-peace heat accumulation efficient low.Finish Chu Leng solidify the dissolving degree of superheat of phase transformation degree of supercooling and heat accumulation the time, the required time is long.
The utility model content
The utility model purpose is the defective that solves above-mentioned prior art, improves the efficient of storage cold-peace heat accumulation, shortens energy storage time, improves rate of energy.
The utility model comprises the accumulation of energy housing, in the accumulation of energy housing phase change medium is set, and the through-hole foamed metal skeleton is set in described phase change medium.
Accumulation of energy housing of the present utility model can adopt the material of high strength, antifatigue high density, good heat conductivity, such as: polymerising ethylene, metal etc.Heat conductivility height, porosity height, density is little, specific area is big through-hole foamed metal material are housed in the accumulation of energy housing, phase change medium utilizes the through hole on the foam metal material to flow, the through-hole foamed metal material plays the effect of skeleton in phase change medium, can change the internal temperature of energy storage equipment rapidly, make the energy storage equipment internal and external temperature reach balance, phase change medium can make water, excellent attitude salt, stone sodium or other phase transformation mixture, thereby improved the efficient of storage cold-peace heat accumulation, further shorten the time of energy storage, reached the purpose that improves energy utilization rate.
The cross section of accumulation of energy housing of the present utility model can be circle.Accumulation of energy this moment housing profile is spherical, can make the internal diameter direction phase transformation of ball even, while is that the unit is deposited in mobile even the flowing of energy storage ball outer fluid in the energy-storing container, interior phase change medium of favourable and energy storage spheroid and ball outer fluid uniform heat exchange, raising heat exchange efficiency with this spheroid.
The cross section of above-mentioned accumulation of energy housing also can be ellipse.Accumulation of energy this moment housing profile is a spheroid, can increase the surface area of unit volume, increases heat exchange area, improves the energy storage heat exchange efficiency.
The cross section of above-mentioned accumulation of energy housing can also be dumb-bell shape.Accumulation of energy this moment housing profile is the dumbbell spheroid, can increase the surface area of unit volume, increases heat exchange area, improves the energy storage heat exchange efficiency.
The cross section of above-mentioned accumulation of energy housing can also be rectangle.Accumulation of energy this moment housing profile is a cylinder, can increase the surface area of unit volume, increases heat exchange area, makes simple simultaneously.
