Abstract
The utility model relates to a phase-change energy accumulating ball, which comprises a ball body and is characterized in that concaves which are arranged evenly and a conical charging port used for filling and sealing energy accumulating material are arranged on the ball body. The taper of the conical charging port is 15 to 25 degrees. The conical structure adopted by the charging port of the energy accumulating ball accelerates the filling speed, solves the wall sticking problem of the energy accumulating material, and increases the sealing-strength and the finished product rate of the energy accumulating ball; the concave structure of the energy accumulating ball leads the volume change of the energy accumulating material to bring little change to the pressure in the ball, the pressure in the ball approximately equals to normal atmosphere, the cracking probability of the energy accumulating ball is thus reduced, and the pressurization index is reduced; a rib type structure is formed among the concaves of the energy accumulating ball, and the accumulation compressive-strength is thus increased.
Description
Technical field
The utility model relates to the device of a kind of accumulation of heat, cold-storage, especially a kind of Energy storage ball.
Background technology
Current, China reaches to world wide, the needs of rapid economy development and household electricity sharp increase are not satisfied in the growth of electric power, short of electricity situation in the whole nation still exists, the network load rate is low, system's peak valley difference is big, peak power wretched insufficiency, peak-valley difference account for the ratio of peak load up to 30%.
Energy accumulating technique is the important method that solves energy resource supply and energy resource consumption coupling contradiction, is to implement the important means that the user then manages, and energy accumulating technique has the function of peak load shifting, can improve efficiency of energy utilization greatly, is the best approach that solves China's power tense.The phase-changing energy-storing technology is the big class energy-storage method of one in the energy accumulating technique, and the phase change cold-storage accumulation of heat stores heat by the phase transformation of medium, compares with sensible heat, and it has energy storage density height, and storage, the approximate isothermal of heat release process, easily and plurality of advantages such as operational system coupling.The phase change cold-storage storage heater is the core component of phase-changing energy-storing power supply device system.Energy storage ball is convenient to batch production, mass production, also is convenient to transportation and through engineering approaches and installs.
China Patent No.: 02215794.8 disclosed a kind of ring grain Energy storage ball; The patent No.: 00259196.0 the Energy storage ball and the patent No.: 03229486.7 metal weights dentation point Energy storage ball.The filled mouth of above-mentioned three kinds of Energy storage balls is straight tube, be unsuitable for the industrialization can of some specific phase-change materials, phase-change material very easily drips in pouring process and looses on the straight tube that fills mouth, and it is unreal to cause it to seal, and very easily causes Energy storage ball material in use to leak; In addition, above-mentioned three patents are not all considered the ball internal pressure variation issue that the Volume Changes of phase-change material in phase transition process brought, and the pressure in the Energy storage ball changes the explosion that can cause heat-storing sphere, cause the leakage of energy-accumulation material in the Energy storage ball.
Summary of the invention
The utility model is that a kind of phase-changing energy-storing ball will be provided, and is used to solve the technical problem that Energy storage ball material in use leaks.
The technical solution of the utility model is: a kind of phase-changing energy-storing ball, comprise spheroid, and be characterized in that spheroid is provided with concave surface and tapered filled mouth that is used for can and seals energy-accumulation material of even layout.
Tapered filled mouthful tapering is the 15-25 degree.
The beneficial effects of the utility model: filled mouthful tapered structure of Energy storage ball has been accelerated filling speed, has solved the adherent problem of energy-accumulation material, has improved Energy storage ball sealing-strength and yield rate; The ball internal pressure that the energy-accumulation material Volume Changes that makes the concave structure of Energy storage ball causes changes little, near normal pressure, has reduced the possibility of Energy storage ball explosion, has reduced the withstand voltage index of Energy storage ball; Form rib type structure between the Energy storage ball concave surface, improved Energy storage ball and piled up compressive resistance.
Description of drawings
Fig. 1 is the utility model Energy storage ball structural representation.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1, phase-changing energy-storing ball of the present utility model is made by the PE material, has uniform concave surface 1-1 on the spheroid 1 of Energy storage ball, has on the spheroid 1 of Energy storage ball to fill a mouthful 1-2, and it fills the tapering that mouth has the 15-25 degree.
Energy storage ball can fill at 85 ℃ environment and seal 79 ℃ phase change heat storage material, and yield rate can reach 99.8%.Use under-25 ~ 95 ℃ environment, ball endosome pressure is near an atmospheric pressure, and its safe piling height can reach 2 meters.
Claims (2)
1. a phase-changing energy-storing ball comprises spheroid (1), it is characterized in that, described spheroid is provided with concave surface (1-1) and tapered filled mouthful (1-2) who is used for can and seals energy-accumulation material of even layout.
2. phase-changing energy-storing ball according to claim 1 is characterized in that, the tapering of described tapered filled mouthful (1-2) is the 15-25 degree.
