Description
Technical field
The utility model relates to a kind of flat type solar heat collector and flat solar water heater.
Background technology
Existing flat type solar heat 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.
During use, 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 of hot and cold water, finishes the heating to water in the water tank.
This flat type solar heat collector heat transfer efficiency is low; Can not be freeze proof, thereby can only be used for south.
Summary of the invention
The purpose of this utility model provides the higher flat type solar heat collector of a kind of heat transfer efficiency.
This flat type solar heat collector comprises housing, transparent cover plate, is arranged on the absorber plate in the housing; It comprises that also an end is that heat collector water inlet, an end are the union pipe of heat collector delivery port; 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 is connected with union pipe.
The utility model adopts the finned heat pipe of evaporator section, and solar energy is changed into heat energy and passes to heat pipe evaporator section, makes the heat-conducting medium gasification of heat pipe evaporator section, reaches behind the heat pipe condenser section heat-conducting medium condensation and emits heat, the water in the heating union pipe.
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 heat collector greatly.
Above-mentioned heat collector 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 heat collector, 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.
The utility model provides a kind of split type flat solar water heater simultaneously, and it comprises above-mentioned flat type solar heat collector and water tank; The heat collector delivery port is higher than the heat collector water inlet; The heat collector water inlet is connected with the cooling water outlet of water tank; The heat collector delivery port is connected with the hot water inlet of water tank.This water heater is the separated type solar water heater that adopts Natural Circulation, and the hot water in the union pipe after temperature raises relies on the density contrast Natural Circulation of hot and cold water, finishes the heating to water in the water tank.
The utility model provides another kind of split type flat solar water heater simultaneously, and it comprises above-mentioned flat type solar heat collector and water tank, and the heat collector water inlet is connected with the cooling water outlet of water tank by the heat collector inlet pipeline; The heat collector delivery port is connected with the hot water inlet of water tank by the heat collector outlet pipeline; On heat collector inlet pipeline or heat collector outlet pipeline, water pump is set.This water heater is the separated type solar water heater that adopts the water pump circulation, and the hot water in the union pipe after temperature raises relies on the water in water pump and the water tank to carry out forced circulation, finishes the heating to water in the water tank.
Two kinds of above-mentioned flat solar water heaters are split type, can combine with building well; Owing to adopt adopting heat pipes for heat transfer, thereby it is fast to conduct heat, the efficient height.
