Description
Technical field
The utility model relates to a kind of solar water heater.
Background technology
Along with society constantly develops, demand for energy is increasing, and the reserves of resources such as coal, oil are fewer and feweri, and the cost of therefore warming oneself is more and more higher, and can produce a large amount of flue gases, flue dust when using resource such as coal, oil, and environmental pollution is serious.Solar energy is a kind of green, clean energy resource, and people more and more pay attention to the utilization of solar energy now.People mainly utilize solar energy to generate electricity and heat at present, and it is exactly photovoltaic cell and solar water heater that people produce corresponding with it product.Solar water heater is and one of gas heater, electric heater three big water heaters mutually arranged side by side.The critical component of solar water heater is a thermal-collecting tube, and in thermal-collecting tube, sunshine and heating agent carry out exchange heat, thereby water is heated to high-temperature from low temperature, uses to satisfy the hot water of people in life, production.Thermal-collecting tube manufacturing cost height, frangible, and grown the incrustation scale that condenses easily service time, maintenance cost is higher, has caused the energy-conservation situation of not saving money of present solar water heater.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of rational in infrastructure, stable at above-mentioned deficiency, and hot water is effective, and use and the low solar water heater of maintenance cost.
For solving the problems of the technologies described above, the design feature of this solar water heater is: the housing that comprises an end opening, the photo-thermal conversion body that receives the sunshine heat is installed in the housing inner chamber, be provided with airtight hot-water cavity in the photo-thermal conversion body, the hot-water cavity bottom is connected with the water inlet pipe that extends to hull outside, hot-water cavity top is connected with the outlet pipe that extends to hull outside, the water side of outlet pipe is equipped with circulating pump, the housing oral area is sealed and installed with the Merlon sunlight board, the circulating pump power supply is electrically connected with AC power by controller, the thermometer that extends in the housing inner chamber is installed, the corresponding electrical connection of thermometer output on the housing with the controller input.
The solar water heater of this structure is to realize stablely by direct projection heat exchange and automatically controlled loop structure, and hot water is effective, and use and maintenance cost are low.
The direct projection heat exchange structure mainly comprises the housing of an end opening, and the photo-thermal conversion body is installed in the housing inner chamber, and the main effect of photo-thermal conversion body is to receive solar light irradiation, and promotes self temperature under solar light irradiation.The housing oral area is sealed and installed with the Merlon sunlight board, the main effect of Merlon sunlight board is printing opacity and insulation, like this, when solar irradiation was mapped on the Merlon sunlight board, most sunshines can pass the Merlon sunlight board and be radiated on the photo-thermal conversion body.At this moment, the temperature of photo-thermal conversion body can slowly raise, and the air themperature in the housing inner chamber and the circulating water temperature in the hot-water cavity are promoted by thermaltransmission mode, finally, make the recirculated water in the hot-water cavity become hot water, make housing inner chamber air become hot-air with higher temperature with higher temperature.The insulation effect of Merlon sunlight board can effectively reduce the thermal loss of housing cavity hot-air, helps the fill-in light heat exchange body further to promote the interior hot water temperature of hot-water cavity.Automatically controlled loop structure mainly comprises the water inlet pipe that is arranged on the hot-water cavity bottom, the water inlet end of water inlet pipe is communicated with the water side of fin, and hot-water cavity top is equipped with outlet pipe, and the output of outlet pipe is communicated with the water inlet end of fin, like this, just constituted the loop of a recirculated water circulation.The outlet pipe end also is equipped with circulating pump, the main effect of circulating pump is with in the hot water suction fin in the hot-water cavity, and cooled backwater in the fin sucked in the hot-water cavity to form circulating water flow, like this, just can utilize the photo-thermal conversion body to provide hot water to fin continuously, thereby play the heating purpose.The circulating pump power line is electrically connected with AC power by controller, and circulating pump gets whether electricly to be controlled by controller.The thermometer that extends in the housing inner chamber is installed on the housing, and the thermometer input is electrically connected with controller induced signal input, and the main effect of thermometer is to transmit housing inner chamber air temperature signal to controller in real time.When sunray was sufficient, the photo-thermal conversion body can improve the temperature of recirculated water in the hot-water cavity rapidly, and simultaneously, the air themperature in the housing inner chamber also can be heated to higher temperature.When cavity temperature in the housing surpasses the controller design temperature, controller promptly starts circulating pump, in the hot water suction fin in the hot-water cavity, and the low temperature backwater in the fin sucked hot-water cavity to form forced circulation, can effectively utilize the photo-thermal conversion body like this, make the heating efficient of this solar water heater reach the highest.When the heated temperature of air in the housing does not surpass design temperature, the circulating pump shutdown, at this moment, the hot water in the hot-water cavity is under the altitude temperature difference effect effect, can slowly move up automatically, and the cold backwater in the fin is slowly sucked in the hot-water cavity chamber to form Natural Circulation by water inlet pipe.No matter be Natural Circulation or forced circulation, all the warm recirculated water of hot-water cavity and the cold backwater in the fin in time can be exchanged, effectively utilized solar energy, need not manual intervention, reliable, cost is low.
As a kind of implementation, described photo-thermal conversion body comprises the circulation pipe of vertical setting, and the circulation pipe upper end is communicated with outlet pipe, and the circulation pipe lower end is communicated with water inlet pipe, is evenly equipped with the backing that is subjected to that is provided with at interval on the circulation pipe.
