Abstract
The utility model provides a flat plate solar water heater with high heat transfer efficiency, which comprises a water tank and a flat plate heat collector, wherein the flat plate heat collector comprises a shell, a transparent cover board and a heat absorption board in the shell, the heat absorption board is formed by a plurality of heat pipes in which heat conductive mediums are arranged, the evaporation sections of the heat pipes are provided with fins, and the condensation sections of the heat pipes are inserted into the water tank to be connected in a sealing type. The utility model adopts the heat pipes of low thermal resistance and high heat transfer efficiency to form the heat absorption boards, thereby improving the heat transfer efficiency of the flat plate solar water heater.
Description
Technical field
The utility model relates to a kind of flat solar water heater.
Background technology
Existing flat solar water heater comprises water tank, flat-plate collector, and flat-plate collector comprises housing, transparent cover plate, is arranged on the absorber plate in the housing.Absorber plate is formed by connecting by copper or aluminium heat absorption fin and copper thermal-collecting tube, the characteristics of this absorber plate are to scribble coating for selective absorption on the absorber plate surface, this coating both can make absorber plate absorb more solar radiation, can reduce the heat loss through radiation loss of absorber plate to environment again.Copper thermal-collecting tube communicates with water tank.Its course of work: sunlight sees through transparent cover plate and shines on the absorber plate, and wherein most of solar radiant energy is absorbed by absorber plate, changes heat energy into, and passes the water in copper thermal-collecting tube.Hot water in the copper thermal-collecting tube after temperature raises relies on the density contrast Natural Circulation with cold water, finishes the heating to water in the water tank.
This flat solar water heater can not be freeze proof, thereby can only be used for south; And it only relies on the density contrast Natural Circulation of hot and cold water, thereby heat transfer efficiency is low; In addition, its water tank usually can not pressure-bearing, and bathing is uncomfortable.
Summary of the invention
The purpose of this utility model provides the higher flat solar water heater of a kind of heat transfer efficiency.
This flat solar water heater comprises water tank, flat-plate collector; Flat-plate collector comprises housing, transparent cover plate, is arranged on the absorber plate in the housing; Described absorber plate is made up of many heat pipes, and heat-conducting medium is arranged in the heat pipe; The evaporator section of heat pipe has fin; The condensation segment of heat pipe stretches into water tank and is tightly connected with it.
The utility model adopts the heat pipe that thermal resistance is little, heat transfer efficiency is high to form absorber plate, can improve the heat transfer efficiency of water heater greatly.
Above-mentioned water heater contains antifreezing agent in the heat-conducting medium.In the heat-conducting medium of heat pipe, add antifreezing agent, and utilize the one-way heat conduction performance of heat pipe, can improve the anti-freezing property and the heat-insulating property of water heater greatly, make dull and stereotyped water heater not only can be used for south, equally also can be used for the north.
Above-mentioned water heater, described water tank are press-bearing water tank.Press-bearing water tank can the pressure-bearing water outlet when bathing, bath comfort.
Above-mentioned water heater, the selective absorber coatings of fin surface.Coating for selective absorption can absorb more solar radiation, can reduce the heat loss through radiation loss of absorber plate to environment again.
Description of drawings
Fig. 1 is flat solar water heater's a side view.
Fig. 2 is the connection diagram of water tank and flat-plate collector.
The specific embodiment
Flat solar water heater shown in Fig. 1,2 comprises water tank 1, flat-plate collector 2.Flat-plate collector comprises housing 3, transparent cover plate 4, is arranged on the absorber plate 5 in the housing.Absorber plate is made up of many heat pipes 6.Heat-conducting medium is arranged in the heat pipe; Contain antifreezing agent in the heat-conducting medium.The evaporator section 7 of heat pipe has fin 8; The selective absorber coatings of fin surface.The condensation segment 9 of heat pipe stretches into water tank 1 and becomes to be tightly connected with water tank wall.
