Abstract
The invention provides a heat storage device used for a solar water heater. The heat storage device used for the solar water heater can effectively solve many problems due to the fact that a traditional solar water heater is provided with a heat insulation water tank. The heat storage device used for the solar water heater comprises a shell and a heat exchanger water pipe, wherein the two ends of the shell are sealed through plugs, the shell is densely filled with a heat storage material, the heat exchange water pipe is buried inside the heat storage material, and the two ends of the heat exchange water pipe both extend out of the plugs.
Description
Technical field
The present invention relates to solar energy heating application, be specially the regenerative apparatus for solar water heater.
Background technology
Mostly traditional solar water heater is to utilize vacuum heat collection pipe that the solar energy of absorption is converted to heat energy and to the cool water heating entered in thermal-collecting tube, because vacuum heat collection pipe only has heat absorption, heat transmission function, therefore the hot water after heating must be stored in guarantee hot water heat in attemperater and not scatter and disappear, there is following defect in it: (1) is stored in attemperater by the hot water after vacuum heat collection pipe heats, the hot water do not used still is stored in water tank, thus cause the hot water Repeat-heating in water tank, and the water of Repeat-heating easily produces material harmful in a large number, therefore the hot water of its heating can not be used for washing foodstuff and drink, the scope of application is little, (2) add water in water tank while being stored in the hot water in water tank and exporting use, then water temperature can be caused unstable, (3) it adds water suddenly when solar energy abundance, easily causes vacuum heat-collecting pipe explosion, thus causes the hot water leak in water tank, there is potential safety hazard, (4) traditional vacuum heat collection pipe solar water heater volume is large, can only be installed on roof or ground, thus cannot adapt to the instructions for use of current skyscraper to solar water heater.
Summary of the invention
The invention provides the regenerative apparatus for solar water heater, it effectively can solve the above-mentioned problems that conventional solar boilers is brought owing to being provided with attemperater.
For the regenerative apparatus of solar water heater, it is characterized in that: it comprises housing, heat exchanging water pipe, the two ends of described housing are all sealed by plug, closely knitly in described housing be filled with heat-storing material, described heat exchanging water pipe is embedded in described heat-storing material and described plug is all stretched out at the two ends of described heat exchanging water pipe.
The periphery wall of described heat exchanging water pipe is provided with heat exchange fin along also uniform on the length direction of described heat exchanging water pipe;
Described heat exchange fin is welded to connect the periphery wall in described heat exchanging water pipe;
Described heat-storing material is the coefficient of expansion≤5% of phase change heat storage material, described phase change heat storage material;
Described phase change heat storage material is preferably paraffin;
Described plug is provided with safety relief valve;
Also be provided with the post that is locked in described housing, described in be locked after post runs through described heat exchange fin, housing, two ends plug and locked by locking nut.
Regenerative apparatus of the present invention is installed in the thermal-collecting tube of solar water heater, the two ends of heat exchanging water pipe respectively with the water inlet pipe of solar water heater, outlet pipe connects, heat-storing material absorbs the solar thermal energy storing and collected by thermal-collecting tube, cold water by water inlet pipe enter heat exchanging water pipe in heat exchanging water pipe with heat-storing material generation heat exchange, thus the heating realized cold water, hot water after heating is discharged for life by outlet pipe, because apparatus of the present invention effectively can store heat energy thus no longer need to configure traditional attemperater, the hot water after heating is preserved, achieve the instant heating of hot water, eliminate the setting of attemperater, therefore greatly can reduce the volume of whole water heater, be convenient to install, it carries out absorption by the heat-storing material of dense packing effect in accumulation of heat storehouse to heat energy and preserves in addition, then heat energy is passed to the water in heat exchanging water pipe by the heat exchanging water pipe be embedded in heat-storing material, and it is even to cool water heating, ensure that the output water temperature of hot water is stablized.
Accompanying drawing explanation
Fig. 1 is the regenerative apparatus of the present invention for solar water heater.
Detailed description of the invention
See Fig. 1, the present invention it comprise housing 10, heat exchanging water pipe 20, the two ends of housing 10 are all sealed by plug 30, closely knitly in housing 10 are filled with heat-storing material 40, and heat exchanging water pipe 20 is embedded in heat-storing material 40 and plug 30 is all stretched out at the two ends of heat exchanging water pipe 20.The periphery wall of heat exchanging water pipe 20 is provided with heat exchange fin 50 along also uniform on the length direction of heat exchanging water pipe, and heat exchange fin 50 is welded to connect the periphery wall in heat exchanging water pipe 20; Heat-storing material 40 is phase change heat storage material, and the coefficient of expansion≤5% of phase change heat storage material; Phase change heat storage material is preferably paraffin; Plug 30 is provided with safety relief valve 70; Also be provided with the post 60 that is locked in housing 10, locked (locking nut 80 is not expressed in FIG) by locking nut 80 after the post 60 that is locked runs through heat exchange fin 50, housing 10, two ends plug 30.After apparatus of the present invention are applied to solar water heater, can arrange multi-path heat exchange water pipe and improve water yield and heat exchange efficiency, in the present embodiment, heat exchanging water pipe 20 is provided with two.
