Description

Adopt self-loopa solar water heater in the hot plate case

The utility model belongs to a kind of use device of solar energy, especially relates to a kind of solar water heater.

The area that the solar energy counterglow time is long is a kind of free of contamination desirable energy, and people have carried out continuous exploration and improvement to the development and use of solar energy.Solar water heater is used to supply with city dweller's domestic water, and is convenient and sanitary.But up to now, prior solar water heater holds at high price, and it is low that equipment is adopted the thermal efficiency, maintenance difficult.Studying carefully its main cause is that thermal-arrest plate and boiler are separated from each other, and is provided with separately, and transmission link is many, and thermal loss is big; Thermal-collecting tube quantity is many, and joint is many, easily leaks, and corrosion is blocked in the easy fouling of caliber inwall on the thermal-collecting tube, and service life is short, and water entry pressure is required high.The weak point of existing solar water heater makes to popularize and is restricted, and particularly in vast rural area and samll cities and towns, still is a blank at present.

The purpose of this utility model provides a kind of compact conformation, and it is hot good to adopt, and temperature retention time is long, and is sturdy and durable, and cheap adopts self-loopa solar water heater in the hot plate case.

The purpose of this utility model is achieved in that water heater comprises that is adopted a hot plate casing, adopts hot plate case heat-insulation layer, transparent heat insulating glass, water inlet pipe, outlet pipe, sealed plastic pipe, shell; Adopt the hot plate casing and place the inside of water heater, the right flank of adopting the hot plate casing is provided with water inlet pipe, and the left surface of adopting the hot plate casing is provided with outlet pipe, adopts on the hot plate casing upper outer wall and scribbles heat absorbing coating, and the top of heat absorbing coating is equipped with transparent heat insulating glass; All the other outer walls of adopting the hot plate casing all are enclosed with heat-insulation layer, and the top end wall of adopting the hot plate casing is provided with exhaust duct aperture.In order to increase the load-bearing of adopting the hot plate casing, in the casing outer setting of adopting hot plate reinforcement, transparent heat insulating glass can be multilayer, leaves the gap and form the insulation air layer between two-layer transparent heat insulating glass, is provided with the sealed plastic pipe between shell and the transparent heat insulating glass.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof, but content of the present utility model is not limited to shown in the accompanying drawing.

Fig. 1 is structure of the present utility model and scheme of installation;

Fig. 2 is the A-A cutaway view among Fig. 1.

Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.

Water heater comprises that is adopted a hot plate casing 3, adopts hot plate case heat-insulation layer 2, transparent heat insulating glass 5,6, water inlet pipe 8, outlet pipe 7, sealed plastic pipe 9, shell 1; Adopt hot plate casing 3 and place the inside of water heater, the right flank of adopting hot plate casing 3 is provided with water inlet pipe 8, the left surface of adopting the hot plate casing is provided with outlet pipe 7, adopt on the upper outer wall of hot plate casing 3 and scribble heat absorbing coating, the top of heat absorbing coating is equipped with transparent heat insulating glass 5,6, all the other outer walls of adopting hot plate casing 3 all are enclosed with heat-insulation layer 2, and the top end wall of adopting hot plate casing 3 is provided with exhaust duct aperture 4.In order to increase the load-bearing of adopting the hot plate casing, at the reinforcement 10 of having adopted hot plate casing outer setting, transparent heat insulating glass is two-layer, transparent heat insulating glass 5, leave the gap between 6 and form the insulation air layer, be provided with the sealed plastic pipe between the bead of shell 1 and the transparent heat insulating glass 5.

This water heater is installed and used very convenient, only need with water heater adopt hot side be transparent heat insulating glass 5 towards Due South, the angle of water heater and horizontal plane is controlled at 25-50 °, optimized angle is 27-35 °.Riding position should be that solar ray energy fully shines, and does not have any shield, and long position of sunshine-duration.Water heater is very extensive because of being suitable for the place, but both extended immobilization was used, and the loading and unloading of can flowing are again used, and the user can suit measures to local conditions only to need to place firmly to get final product with stone, brick, timber or the angle steel fixed support as water heater.

The utility model when work, after adopting water in the hot plate casing and absorbing the heat of the sun, can self-loopa under the effect of the temperature difference and gravity be heated, heat exchange, can supply with hot water through the irradiation of a few hours.The user can choose the water heater that capacity is 80 kilograms or 120 kg according to demand separately, is example with state, Chuxiong, Yunnan Province, is 43-52 ℃ through reality test fine average water temperature in winter; Summer, water temperature can reach 73-80 ℃, can satisfy actual needs fully.

Compared with prior art, the utlity model has following outstanding advantage:

1, collecting plate and boiler organically being combined, is the breakthrough to existing solar water heater structure, Fundamentally reduce the energy exchange number of times. Water circulation and water heater Performance Ratio are 100Kg/m in the case², and the commercially available prod Performance Ratio only is 50-60Kg/m at present², make the utilization ratio of solar energy improve nearly 1 times;

2, be skillfully constructed, rational in infrastructure, product has reduced a lot of consumable accessorys, efficiently solves the mill run collection The easy fouling obstruction of caliber inwall on the heat pipe, short defective of burn into life-span, product is durable in use;

3, cheap, price only is the 1/3-1/5 of existing product, and consumers in general more are ready to buy and glad the use;

4, properties of product are stable, and less demanding to source pressure, adaptability is good, will have huge market in vast rural area and middle samll cities and towns.To the rural area energy savings, reduce environmental pollution, the aspects such as hot water demand of improve sanitary condition and not timing all bring convenience; Especially to solving the rural area, will produce great economic benefit and social benefit because of the thorny problem that fuel destroys the forest reserves has immeasurable effect.
