Description

The flat solar water heater

The utility model belongs to a kind of box-type solar water heater.

The energy is human survival at one of necessary factor of development, and along with the development of industrial and agricultural production and the rapid raising of people's living standard, the consumption of the energy is increasing, and the energy lacks serious day by day, therefore, must accelerate development with utilize new forms of energy.

Solar energy is the inexhaustible not intact non-polluting energy sources of using.Therefore countries in the world are all attached great importance to the development and use of solar energy.Solar energy utilization at present mainly is at aspects such as generating, solar energy stove and solar water heaters.Solar water heater has easy capsule formula water heater, and cold water is packed in the black plastic capsule bag, is placed on places such as roof or platform, utilize solar energy heating water, use for the user, as have a bath or wash clothes etc., but this Simple Solar Water Heater is subjected to weather effect big, and then can't use winter.Another kind is to adopt the vacuum glass housing, in spiral absorber is set, water pipe is then along the formula setting in the shape of a spiral of spiral absorber, cold water is heated in water pipe enters water heater, output hot water is for using, though this solar water heater is subjected to weather effect little, Dong Xia can use, but cost an arm and a leg, be not easy to utilization and extention.

The purpose of this utility model provides a kind of thermal efficiency height, is subjected to that weather effect is little, spendable flat solar water heater of summer in winter.

The utility model adopts following technical proposals to realize, that is:

The flat solar water heater comprises heater box, water tank, ground floor transparency glass plate, second layer transparency glass plate, air expansion and contraction adjuster and case lid.On heater box's inwall, heat-insulation layer is set.Water inlet pipe through hole and outlet pipe through hole are arranged on heater box's the sidewall.Be fixed with water inlet pipe and outlet pipe on the sidewall of water tank, the water tank upper surface is the black absorber plate.Water tank is arranged in the heater box, and water inlet pipe on the water tank sidewall and outlet pipe the water inlet pipe through hole from the water heater tank body sidewall and outlet pipe through hole respectively stretch out outside the casing.In the heater box, water tank upper sets gradually second layer transparency glass plate and ground floor transparency glass plate, leaves certain interval between the two-layer transparency glass plate.The air expansion and contraction adjuster is come in and gone out to manage by adjuster casing and two air and is formed, the adjuster casing is arranged on water heater tank one end external, two air discrepancy pipes and links with the adjuster casing respectively, the other end passes two air discrepancy pipe jacks on the water heater tank body sidewall respectively, stretches between ground floor and the second layer transparency glass plate.Case lid and heater box are hinged, and aluminum plating reflective membrane is posted in the upper surface of case lid.

Above-mentioned air expansion and contraction adjuster also can be arranged in the heater box.

The water tank upper surface can be rough black absorber plate.

In order to make water tank capacity adjustable, the sidewall all around of water tank is the extension type corrugated plating.

For the temperature that makes water in the water tank is even up and down, can be in water tank middle part horizontally set stainless (steel) wire.

Can on above-mentioned heater box lower surface, support be set.

The utility model can be arranged on roof, balcony or be suspended on the wall, also can be arranged on the place of other sunlight foot.Import cold water in the heater box, through the water heater upper surface, promptly rough black absorber plate absorbs solar energy, and the interior water of casing is heated, and output hot water uses for the user, because the utility model is provided with two-layer transparency glass plate, so the heat-insulating property height.The utility model is at 42 ° of north latitude, 123 ° of east longitudes, the sunny weather of winter-13 ℃, and 10: 30 morning, 40 kg water, water temperature can reach 60 °-80 ° to point in afternoons 15.

Because the utility model water tank capacity is adjustable, can dwindle water tank capacity winter, accelerates to improve water temperature speed.

The utility model is provided with the purpose of air expansion and contraction adjuster; be that the gas that expands when the air expanded by heating between the two-layer transparency glass plate that is provided with in the casing can enter the adjuster case; when two-layer transparency glass plate with gas Yin Wendu descend and when shrinking; gas in the adjuster adds to again in the interlayer of two-layer transparency glass plate; the balance that keeps the air pressure in this interlayer, the protection transparency glass plate is not damaged.

The utility model is simple in structure, cost is lower, be subjected to weather effect little, can use throughout the year.

Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the A-A view of Fig. 1, and Fig. 3 is the assembling process schematic diagram of heater box, water tank, transparency glass plate, and Fig. 4 is adjustable water tank schematic diagram.The utility model is described in further detail below in conjunction with accompanying drawing.
