Abstract
The utility model discloses a straight-through circle-flowing solar-power water-heater, belonging to the technical field of solar-power water-heater. The utility model comprises a main water tank and a heat-collecting pipe. An insulation layer is arranged on the outside of the main water tank and a plurality of heat-collecting pipes are arranged below the main water tank, the upper end of the heat-collecting pipe is communicated with the main water tank, and a flow-guiding box communicated with the lower end of the heat collecting pipes is arranged below the heat collecting pipes. The utility model has high heating efficiency without furring and dust sediment at the bottom of the heat collecting pipes.
Description
Technical field
The utility model relates to a kind of solar energy heat collector, and particularly solar water heater belongs to technical field of solar water heaters.
Background technology
Solar water heater of the prior art, mainly by main water box, formations such as thermal-collecting tube, described main water box is provided with heat-insulation layer outward, and thermal-collecting tube has some and be arranged at the below of main water box, the thermal-collecting tube lower end closed, the upper end communicates with main water box, and under the irradiation of sunlight, the water in the thermal-collecting tube is heated, because the density of hot water is less than the density of cold water in the main water box in the thermal-collecting tube, so hot water can rise, cold water can descend, thereby forms circulation, but in cyclic process, when ascending current and descent waterflow meet in thermal-collecting tube, can influence each other, form turbulent flow, it is bad to cause conducting heat, and efficient is low; Again because the thermal-collecting tube lower end closed uses meeting at thermal-collecting tube inner bottom part formation incrusted deposit and sediment settlement for a long time, especially for the relatively poor area of water quality, because the influence of incrustation scale and silt can make the thermal efficiency of solar water heater very low, even can't use.
The utility model content
The purpose of this utility model provides a kind of straight-through circulating type solar energy water heater, make its thermal efficiency height, and the thermal-collecting tube inner bottom part does not have incrusted deposit and sediment settlement.
The purpose of this utility model is achieved in that straight-through circulating type solar energy water heater, comprise main water box and thermal-collecting tube, described main water box is provided with heat-insulation layer outward, described thermal-collecting tube has some and be arranged at the below of main water box, the thermal-collecting tube upper end is connected with main water box, and the thermal-collecting tube below is provided with the guide tank that is connected with the thermal-collecting tube lower end.
Under the irradiation of sunlight, water in the thermal-collecting tube is heated, owing to more or less have individual difference between each root thermal-collecting tube, the heat absorption capacity of each thermal-collecting tube is had nothing in common with each other, and then make water temperature difference in each thermal-collecting tube, thereby between each thermal-collecting tube, form circulation through main water box and guide tank, to be water rise in some thermal-collecting tube enters main water box, descend from the other thermal-collecting tube again, enter guide tank, enter in the thermal-collecting tube of ascending current from guide tank again, form circulation, make heat-transfer effect good, thermal efficiency height; Owing to communicate up and down in the thermal-collecting tube, under current scour, the pipe inner bottom part does not have incrusted deposit and sediment settlement again.
As further improvement of the utility model, described guide tank is established heat-insulation layer outward.This technical scheme can reduce the heat radiation of guide tank, further improves the thermal efficiency.
As further improvement of the utility model, be provided with circulating pipe between described main water box and the guide tank, the circulating pipe upper end is connected with main water box, and the lower end is connected with guide tank.When work, the continuous rising of hot water enters main water box in the thermal-collecting tube, is advanced into guide tank from main water box under circulating pipe again, the water of guide tank constantly replenishes and enters thermal-collecting tube, forms orderly circulation, can make the water circulation more reasonable, force of circulation is strong, and the thermal efficiency is higher.Described circulating pipe can be the thermal-collecting tube of outsourcing reflectance coating, also can be one or two communicating pipes that are communicated between main water box and the guide tank of peripheral hardware.
As further improvement of the utility model, described guide tank bottom is provided with exhaust-valve.When cold weather, can open the water in the exhaust-valve emptying water heater, in case thermal-collecting tube is freezing; Also can carry out periodical blowdown, further reduce the possibility of incrustation and sediment settlement.
Description of drawings
Accompanying drawing is the utility model structural representation.
Wherein, 1 guide tank, 2 circulating pipes, 3 thermal-collecting tubes, 4 main water box, 5 heat-insulation layers, 6 permeability cells, 7 upper and lower conduits, 8 exhaust-valves.
The specific embodiment
As figure, solar water heater, mainly constitute by main water box 4, guide tank 1, circulating pipe 2 and thermal-collecting tube 3 etc., be provided with heat-insulation layer 5 outside main water box 4 and the guide tank 1, also be provided with permeability cell 6 and upper and lower conduit 7 on the main water box 4, thermal-collecting tube 3 has 15, be positioned at the below of main water box 4, thermal-collecting tube 3 upper ends communicate with main water box 4, and guide tank 1 is located at thermal-collecting tube 3 belows, and thermal-collecting tube 3 lower ends are connected with guide tank 1; Circulating pipe 2 has one, is arranged at a side of main water box 4 and guide tank, and circulating pipe 2 upper ends are connected with main water box 4, and the lower end is connected with guide tank 1; Guide tank 1 bottom is provided with exhaust-valve 8.
The utility model is not limited to the foregoing description, and described thermal-collecting tube can be some; Described circulating pipe can be the thermal-collecting tube of outsourcing reflectance coating, also can be one or two communicating pipes that are communicated between main water box and the guide tank of peripheral hardware.
