Abstract
The utility model provides a bag type solar energy water-heating unit with an insulating band, which is made of plastic film, etc. The water-storing heat-collecting bag (inner bag) of the bag type solar energy water-heating unit with an insulating band is made of the black plastic film or the soft plastic film wall. An inlet and outlet water pipe and an exhaust overflow pipe are arranged on the water-storing heat-collecting bag. The outside of the water-storing heat-collecting bag is covered by a heat-insulating jacket made of the colorless transparent plastic film. Sunlight can penetrate through the heat-insulating jacket and beat down on the water-storing heat-collecting bag. The heat-insulating jacket charged with the air can prevent effectively the hot water radiating outwards in the water-storing heat-collecting bag. The bag type solar energy water-heating unit with an insulating band, which has the advantages of high heat efficiency, favorable heat insulating property, material saving, simple manufacture technology and low cost is suitable for families and outdoor workers.
Description
The present invention's a kind of solar water heater that adopts the band insulation jacket that the flexible plastic thin-walled material makes of touching upon.
Prior art is the pocket type solar water heater with plastic production, adopts black plastic film to constitute water storage thermal-arrest bag, water-filling in the bag, and solar irradiation is mapped to the sack surface, and the water in the bag is heated.Because the sack outside does not have attemperator, the heat of hot water outwards scatters and disappears easily in the bag, so the thermal efficiency of this pocket type solar water heater is lower.
In view of the above-mentioned shortcoming of existing pocket type solar water heater, task of the present invention provides the pocket type solar water heater of the higher band insulation jacket of a kind of thermal efficiency.
The present invention is achieved in that at one preferably is equipped with a water inlet outlet pipe in the bottom of the water storage thermal-arrest bag that constitutes of black plastic film or flexible plastic thin-walled material by dark colour, and the exhaust overflow pipe is equipped with at the top of this sack.The outside of water storage thermal-arrest bag is coated with the insulation jacket that is made of colourless transparent plastic film or plastic sheeting moulding material, and makes the institute that forms between insulation jacket and the water storage thermal-arrest bag have living space and be full of air.Water can be injected or discharges water storage thermal-arrest bag by the water inlet outlet pipe.When water filling in water storage thermal-arrest bag, air in the bag and excessive water can be discharged from the exhaust overflow pipe.Sunshine can see through the surface that insulation jacket shines water storage thermal-arrest bag from all directions, is absorbed by this surface and is transformed into heat energy, and the water in the bag is heated.Because the thermal resistance Buddhist nun of air effect in insulation jacket material and the chuck, the speed of the outside heat radiation of hot water slows down greatly in the water storage thermal-arrest bag.
The solar water heater of band insulation jacket of the present invention because water storage thermal-arrest bag outside is coated with the insulation jacket that is full of air, can stop bag interior hot water outwards to dispel the heat effectively, therefore, has the higher thermal efficiency, and makes the time lengthening of hot water thermal insulating.
Specific embodiments of the present invention now is illustrated in conjunction with the accompanying drawings.
Fig. 1, Fig. 2 and Fig. 3 are the accompanying drawings of embodiment one, and wherein Fig. 1 is a front view, and Fig. 2 is the A-A cutaway view, and Fig. 3 is the B-B profile.
Fig. 4, Fig. 5 are the accompanying drawings of embodiment two, and wherein Fig. 4 is a front view, and Fig. 5 is the C-C cutaway view.
Embodiment one
Water storage thermal-arrest bag (1) adopts black plastic film or flexible plastic thin-walled material to constitute, and its thickness is preferably 0.3-0.8 millimeter of 0.2-1.5 millimeter.In the bottom of water storage thermal-arrest bag (1) a water inlet outlet pipe (2) is housed, an exhaust overflow pipe (3) is equipped with at the top of this sack.The all outer surfaces of water storage thermal-arrest bag (1) is coated with the insulation jacket (4) that one deck is made of the colourless transparent plastic film, its thickness is preferably 0.2-0.5 millimeter of 0.1-0.7 millimeter, and make the plenum space (5) that is connected to form some the corrugated that interconnect between the outer surface of insulation jacket (4) and water storage thermal-arrest bag (1), can fill air to all plenum spaces (5) by a gas tube (6) that is installed on the insulation jacket (4).
Embodiment two
The difference of the present embodiment and above-mentioned embodiment one is, the insulation jacket of the present embodiment (4) is made of the colourless transparent plastic film forming material of the minute bubbles that have dense arrangement, and in each minute bubbles and the space between insulation jacket (4) and the water storage thermal-arrest bag (1) all is full of air once.
Claims (1)
1, a kind of pocket type solar water heater that adopts the band insulation jacket of flexible plastic thin-walled material making, has water storage thermal-arrest bag (1), water inlet outlet pipe (2), exhaust overflow pipe (3), it is characterized in that water storage thermal-arrest bag (1) outside has the insulation jacket (4) that is made of colourless transparent plastic film or plastic sheeting moulding material, forms the plenum space (5) that is full of air between insulation jacket (4) and water storage thermal-arrest bag (1).
