Abstract

The utility model relates to an all-weather solar water heater, which is characterized in that the utility model is provided with a heat collection part and a heat storage part. A heat storage box 1 is a container with an integral thermal insulation heat-insulating layer, and a solid heat-insulating layer is formed by a plurality of kinds formulation liquids via the special treatment. The heat storage box i is arranged above a heat collection pipe 6. The utility model has the advantages of fast heat collection, high heat storage capacity, and low heat loss. The water temperature in the tank can reach above 80 DEG C. After three consecutive rainy weather days, the water can still be kept by 70 DEG C. The utility model completely can be used in winter, rainy days and the early morning in all-weather. The utility model is especially suitable for the family washing, bathing, and heating.

Description

All-weather solar-energy water-heater

The utility model relates to a kind of solar water heater.

Usually solar water heater is by the parallel connection of several thin metal tubes, and the outside scribbles heat absorption paint, is installed in the case glass of case face.After metal cylinder is full of cold water, utilizes the width of cloth that absorbs sunshine to penetrate and improve water temperature.The one because thermal-arrest and heat accumulation function coexist causes when overcast and rainy, and water temperature descends with temperature, loses hot water function, more can't night, early morning and winter use.

The purpose of this utility model provides a kind of separates thermal-arrest and heat storage structure, and thermal-arrest is fast, quantity of heat storage is big, the all-weather solar-energy water-heater of good heat insulating.

The utility model is achieved in that by institutes such as thermal-arrest and heat accumulation two parts and water inlet pipe and water outlet pipe 11, support 13, underframe 14 to be formed, and the thermal-arrest part is fixed on the reflective panel 8 with 7 arrangements of location fixing collar by some vacuum heat collection pipes 6.Heat accumulation partly is a heat storage box 1, and heat storage box 1 is by shell 2, thermal insulation interlayer heat-insulating material 3, and inner casing 4 is formed.Heat storage box 1 is supported and is fixed on the underframe 14 by support 13 by putting above the thermal-arrest part.The lower end of the openend of vacuum heat collection pipe 6 and heat storage box 1 is connected through sealing ring 5 and communicates, and also can be tightly connected by soft, rigid tubing communicates.

Elaborate below in conjunction with accompanying drawing:

Fig. 1, all-weather solar-energy water-heater sectional plan view.

Fig. 2, all-weather solar-energy water-heater left view.

Fig. 1, shown in Figure 2, the utility model mainly is made up of thermal-arrest and heat accumulation two parts, thermal-arrest partly is by vacuum heat collection pipe 6, generally about 10, also can select for use between 5～100, arrange as required and be fixed on the reflective panel 8 with location fixing collar 7, spread pattern is generally the individual layer linearity, see shown in Figure 2, also can the individual layer curve-like, double-deck curve-like.Vacuum heat collection pipe 6 is a kind of double-layer glass tubes, and intermediate course is a vacuum, and outer wall is transparent, inner wall outside scribbles the heat absorption blacking, can make light easily see through outer wall glass like this, the water temperature in making in the pipe rises, and improves collecting efficiency with the reverberation on the reflective panel 8.Because laminated vacuum is as the glass liner of a thermos flask, heat can not distribute by glass tube, and vacuum heat collection pipe 6 has played the function of heat " only import but no export ".Heat accumulation partly is a heat storage box 1 with interlayer container, make by shell 2 and inner casing 4 usefulness thin metal plates, adopt thermal insulation interlayer heat-insulating material 3 between shell and the inner casing, this insulation material is to select for use two kinds of liquid materials to mix mutually to inject interlayer, and it is solid-state through chemical reaction liquid state to be become, and is the whole thermal insulation layer that is filled in the every nook and cranny, wrap up whole inner casing, with extraneous do not contact the inner casing 4 of metal immediately with the heat storage box sealing this moment, can not carry out the heat conduction.Heat storage box 1 volume is changeable, is generally prism and sees Fig. 1, also can make other shapes such as Cylinder, and is horizontal above the thermal-arrest part.Heat storage box 1 is supported by angle iron bracket 13, and is fixed on the underframe 14 with fixed screw 15.Facts have proved that heat storage box 1 volume is bigger, heat accumulation water the more, the performance of heat accumulation is better.Arrangement is fixed on the vacuum heat collection pipe 6 on the reflective panel 8, and length is 1 meter～1.5 meters, end sealing, one end opening, see Fig. 2, its openend and heat storage box 1 lower end are connected by sealing ring 5 and communicate also that soft, the rigid tubing of available good heat insulating are tightly connected, and are convenient to install move.Connect by set screw 9 between reflective panel 8 and the underframe 14, by the user according to location, position, adjustment optimal light irradiation angle.There is spilling water air bleeding valve 10 on heat storage box 1 top, when being full of water and boiling in the case, discharges automatically outside the case, prevents explosion.Blowoff valve 12 is arranged at heat storage box 1 bottom, can regularly the sediment in the water be discharged, and guarantees water cleaning.In the bottom of heat storage box 1 water inlet pipe and water outlet pipe 11 is arranged, see Fig. 1, when cold water enters from water inlet pipe and water outlet pipe 11, be full of in the case and after in the pipe, under solar radiation, water temperature improves in the vacuum heat collection pipe 6, and rising automatically enters in the case, and the case inner cold water sinks to being back in the vacuum manifold 6, water temperature improves constantly in the heat storage box 1 like this, stored a large amount of hot water, under any weather condition, round-the-clock use.

Because solar water heater closes thermal-arrest and heat accumulation in one usually, it is fast just must thermal-arrest to occur, and the also fast contradiction of dispelling the heat can't round-the-clockly be used.The utility model thermal-arrest is fast, good heat insulating, and water temperature can reach more than 80 ℃ in the actual measurement case, through rainy weather at continuous three days three nights, only reduces by 10 ℃, can not be subjected to weather effect fully and obtains hot water.The utility model can partly be made thermal-arrest small-sized, is placed on outside the balcony, and heat storage box 1 is placed in the balcony, makes that non-top layer resident family also can use in the apartment, and it is also convenient to install.Also thermal-arrest and heat accumulation partly can be made large-scalely, volume enlarges, and as flowing into large-scale brooder, improves room temperature, for winter planting with make boiler preheating water and use.
