Can embed the solar water heater in the body of wall
Technical field
The utility model belongs to the design and the manufacturing technology field of solar water heater.
Background technology
People's employed solar water heater in life is made of support, thermal-collecting tube and water tank at present.Bulky, cost an arm and a leg.Because of this water heater all is to be placed in the dwelling house roof, for low layer resident family, it supplies, water return pipeline is oversize, easy bursting by freezing in winter.Because pipeline is long, cause out the preceding a large amount of cold water of hot water to slattern in addition.Be exactly that water heater is put the in disorder appearance of the city that influences at roof in addition.Therefore say that existing solar water heater is not very desirable in design.
Summary of the invention
The purpose of this utility model provides a kind of solar water heater that embeds in the building wall.To solve the problems referred to above that existing product exists.
Structure of the present utility model is as shown in drawings: be made of storage tank and heat-collecting box.On storage tank top one overflow pipe is arranged.On right side, storage tank bottom one water inlet pipe and water outlet pipe is arranged.The storage tank outside has heat-insulation layer.In the storage tank bottom one heat-collecting box is arranged, working media is housed in the heat-collecting box.Have the thermal-arrest plate on the heat-collecting box front, have infrared ray heat-absorbing paint layer on the thermal-arrest plate face.Have evacuated transparent in thermal-arrest plate front.Have the circulation heating tube in storage tank, the two ends of heating tube link to each other with heat-collecting box.One end stretches into the heat-collecting box bottom, and the other end is arranged on heat-collecting box top.The heat-collecting box outside has the heat-collecting box heat-insulation layer.The water inlet pipe and water outlet pipe of storage tank bottom connects running water and user's tap.The heat-collecting box of this product is a cuboid, and ultrathin design can be embedded in the sunny slope body of wall, also can be suspended on the sunny slope wall.It is indoor that storage tank is placed in resident family.The operation principle of this product is: when sunshine is radiated at by the vacuum glass outer cover on the thermal-arrest plate face, the thermal-arrest plate absorbs heat the working media in the heat-collecting box is heated.After medium was heated, proportion changed, and the medium light specific gravity of heat upwards flows by heat-collecting box top circulation heating tube, heat is conducted to the water in the storage tank, thereby water is heated.The interior medium temperature of the heating tube that circulates simultaneously reduces cooling, and proportion increases, and flows back to heat-collecting box downwards.Medium constantly is heated, and reciprocation cycle constantly heats up the water in the storage tank.Characteristics of the present utility model are simple in structure, do not have support and very long upper and lower conduit, can reduce cost, again because upper and lower conduit is short out and indoor, do not exist by the problem of bursting by freezing winter.The used working media of this product adopts such as motor vehicle antifreeze fluid, transformer wet goods.Operating temperature can be at-30 ℃~100 ℃.So this product can normally use in the winter time.It is applicable to and the supporting building of residential building.When building the building, heat collection water tank is constructed in the sunny slope body of wall.Can also beautifying constructure.
