Description

Efficient solar water heater

One, technical field

The utility model relates to a kind of efficient solar water heater, belongs to utilize solar energy to carry out hot water heating device technique field.

Two, background technology

Prior solar water heater mainly is to utilize vacuum tube or metal tube to absorb solar heat to be transmitted to the attemperater energy storage again, and the output of hot water is by the quantity decision of endothermic tube.Because endothermic tube cost height, the open-air use material requirements of attemperater is also high, so whole water heater cost height, the family of general low income is difficult to accept, and in addition, has between certain fluffy between endothermic tube is arranged, can not absorb the solar thermal energy in certain areal extent fully, heat absorption rate is reduced.

Three, summary of the invention

The utility model provides a kind of solar thermal energy that can fully absorb in certain areal extent, utilization rate height, the efficient solar water heater that cost is low.

Efficient solar water heater of the present utility model comprises endothermic water tank and heat-storage heat-preserving case, it is characterized in that the endothermic water tank is made of the double-layer tank main body of a top opening and the anti-heat radiation of the printing opacity double glazing unit that is contained on the water tank main body, between the water tank main body is two-layer, heat-insulation layer is arranged, water tank main body inner wall and bottom surface scribble heat-sink shell, water tank bottom part body two ends have cold water inlet and hot water outlet respectively, the oral siphon of the anti-spill valve of band control endothermic water tank water depth is housed at endothermic water tank's cold water inlet place, hot water exit's attaching has the conveyance conduit of band hot water outlet switch, and the endothermic water tank is equipped with fixed support in the bottom; The energy storage incubator is a double-decker, and the heat-insulation layer of 15-35mm is arranged between layer and the layer, at energy storage incubator top the hot water inlet is arranged, and the outlet of heat supply water is arranged at the bottom, and the hot water inlet is connected with the conveyance conduit that is connected to endothermic water tank's hot water outlet.

Described endothermic water tank's height overall is 80-100mm, and the heat-insulation layer between the double-layer tank main body is two-layer is 15-25mm, and the double glazing unit interlayer on the water tank is spaced apart 15-25mm.

This water heater working process is as follows: the sun sees through double glazing unit and shines directly into water layer, water layer directly absorbs heat, the heat-sink shell that reaches the bottom surface around the tank inner wall constantly absorbs heat, because the heat-insulation layer insulation is arranged at around the water tank and bottom, there is double glazing to prevent that heat scatters and disappears above, make the water in the water tank heat up comparatively fast high insulating effect.The speed that water temperature rises is relevant with the depth of water layer, the shallow quick heating of water layer, and water layer is dark to heat up slowly, so, use shoaling layer winter, use profundal zone spring and summer.Treat that water temperature is raised to and to open hot-water switch when temperature required and discharge water stand-by into the heat-storage heat-preserving bucket.

The output of this water heater production hot water depends mainly on endothermic water tank's area, and the area of general approved product is 2m ²But 80 liters in heat production water can be adorned more than 2 as required.

Efficient solar water heater manufacturing of the present utility model is simple, heat absorption efficient height, and cost is low, is applicable to that vast town and country apply.
