Description

Anti-freezing type cistern free high-efficient flat-plate solar water heater
Technical field
The utility model relates to a kind of anti-freezing type cistern free high-efficient flat-plate solar water heater, belongs to the solar water heater field.
Background technology
Existing panel solar hot water is by flat plate collector, heat storage water tank, support, connecting pipe, the compositions such as control assembly.Wherein the heat storage water tank cost is higher, has accounted for most of totle drilling cost.Also there is in addition following shortcoming: the one, water tank is installed complicated, and volume takes up space more greatly.The 2nd, flat plate collector is connected with water tank, water tank and user's water connecting line are more, and the pipeline heat waste is more.The 3rd, the system maintenance trouble.The 4th, various parts is installed in disorder not attractive in appearance.
Application number is " 201010141755.5 ", the Chinese invention patent application that invention is called " a kind of heat accumulation type flat-panel solar water heater without water tank " discloses a kind of heat accumulation type flat-panel solar water heater without water tank, the shell that comprises an opening, be provided with absorber plate and accumulation of heat rod in the shell, the accumulation of heat rod is comprised of inner tube, outer tube and heat-storing material, heat-storing material is located between inner tube and the outer tube, outer tube is fixedly connected with absorber plate, outer tube is fixedly connected with shell, accumulation of heat rod one end connects water inlet pipe, and the other end connects outlet pipe.The accumulation of heat rod is more than two, and the accumulation of heat rod is connected in parallel between water inlet pipe and the outlet pipe.The inner tube two ends are provided with nipple, and an end of inner tube is connected water inlet pipe by nipple with nut, and the other end is connected outlet pipe by nipple with nut.Accumulation of heat rod and weary of shell are provided with heat-insulation layer.Be provided with the expansion space of heat-storing material between inner tube and the outer tube.Heat-storing material is phase change heat storage material.This technical scheme theory is to absorb heat by absorber plate, connect heat conduction by outer tube and absorber plate, reach among the heat accumulating phase change material that is arranged between inner tube and the outer tube after the simultaneously outer tube heat absorption, heat conduction by inner tube and heat-storing material during use realizes heat exchange, make an end of its inner tube enter cold water, and another brings out hot water, although can reach heat absorption theoretically, the course of work of heat accumulation and heat release also realizes the flat plate solar water heater that cistern free arranges, but still have the following disadvantages during practice: 1. absorber plate heat absorption, suction disc is connected heat transfer with outer tube, because the contact area of outer tube and absorber plate is little, thereby make the utilization rate of heat energy of the absorber plate of same unit are or flat-plate solar collector lower, simultaneously heat conducting efficient is also very low, for example when winter then the water heater of this technical scheme can't normally go out hot water and use at any time for the user; 2. because the phase change heat storage material heat accumulation of outer heat transfer pipe and outer tube and inner tube, the magnitude setting of the flat plate collector middle external tube of unit are is limited simultaneously, that heat absorption capacity is relatively poor on the one hand, on the other hand, when even sunlight is sufficient, when the heat that outer tube absorbs is more, because the space of heat-storing material is less, thereby must make its quantity of heat storage of unit are limited, therefore can't to provide the hot water temperature relatively low for this scheme, and provide the amount of hot water less, so bring a lot of inconvenience in the utilization process of reality, the value of utilization is not very high.
Application number is " 201110140960.4 ", denomination of invention is: the Chinese invention patent application of the flat phase-transition heat-storage type solar energy heat utilization device of a kind of cistern free discloses the flat phase-transition heat-storage type solar energy heat utilization device of a kind of cistern free, it is characterized in that it mainly comprises metal shell, canister, heat exchange pipeline and cover layer transparent vacuum cover plate on canister, be packaged with phase-change heat-storage material in its genus container, the upper surface of canister is coated with coating for selective absorption, and absorber coatings is direct and phase-change heat-storage material, and described heat exchange pipeline is arranged in the phase-change heat-storage material.Thereby being directly conducted to phase-change heat-storage material, the heat energy that absorber coatings is inhaled makes its phase-change thermal storage, can be directly by the water inlet of heat exchange pipeline water inlet end when the user uses hot water, heat exchange to water side water outlet realization and phase-change heat-storage material realizes, this technical scheme is from absorbing the heat angle, in the general sun-drenched situations such as fine day, endothermic effect is better, the heat exchange efficiency of its heat absorption is higher, but because the conduction of heat energy is two-way, when only having rainy weather or night, because the temperature of absorber coatings is with extraneous identical, when the temperature in the heat storage phase-changing material was higher than absorber coatings, then corresponding heat storage phase-changing material can be to extraneous heat by conduction energy, its heat insulation effect is relatively poor, unless the heat that absorbed the same day was used up by water that night, otherwise the loss of heat is larger, actual use value is not high.
