Problems solved by technology

The insulation layer of the water tank and heat collection tank is usually foamed polyurethane, with only 80% of the closed cells, and the overall foaming can only have a good insulation effect under airtight conditions; not only the cost of raw materials is high, but also the processing and production are very complicated
Although the shell structure of the water tank and heat collecting tank is strong, it is very difficult to repair once damaged
The raw material and production cost of the liner of the water tank are high
The transparent cover, especially the transparent cover of polycarbonate (PC), is soft and has a large range of thermal expansion and contraction, so it is difficult to solve the problem of its surrounding fixation and the middle part of the downward collapse

Embodiment 1

[0028] Such as Figure 1-4 Shown, the incubator of the present invention is the extruded board square box 11 of four side walls and top or bottom. For weather resistance and anti-ultraviolet rays, the outer surface that is exposed to the sun, that is, the outer side and the outer top surface, has a good exterior wall latex paint or EVA or weather-resistant adhesive or aluminum foil or other weather-resistant protective layer 12 with white. figure 1 and figure 2 It is a top insulation box, mainly used as the top and side shell of the solar water heater tank, such as Figure 6 and 7 , the outer top surface and the outer side that can be illuminated by the sun have exterior wall latex paint or other weather-resistant protective layers 12 that are preferably white. image 3 and Figure 4 It is a bottom insulation box, mainly used for the shell of the heat collection box of the flat plate collector, such as Figure 10-13 , white exterior wall latex paint or other weather-resi...

Embodiment 2

[0031] Such as Figure 6 Shown, the water tank of the flat solar water heater of the present invention, and background technology such as Figure 5 The shown water tank is the same, and is made up of structural layer 1, insulation layer 2, liner 3, upper circulation pipe 4, lower circulation pipe 5, water inlet pipe 6, water outlet pipe 7 and breathing overflow pipe 8. It is characterized in that: the top and side shells of the water tank are extruded board insulation layer outer cover, that is, the insulation box described in embodiment 1, and the structure layer 1 and the inner tank 3 are in sequence inside. The bottom seam of the incubator and the water tank can be sealed with EVA tape or other adhesives, and it is very convenient to remove and replace. Of course, the insulation layer material at the bottom of the water tank is also preferably extruded board.

Embodiment 3

[0033] This is the preferred technical scheme of embodiment 2. The upper circulation pipe 4, the lower circulation pipe 5, the water inlet pipe 6, the water outlet pipe 7 and the breathing overflow pipe 8 of the water tank are vertically fixed at the bottom of the water tank. Because the upper circulation pipe 4, the lower circulation pipe 5, the water inlet pipe 6, the water outlet pipe 7, and the breathing overflow pipe 8 are mainly fixed by the force of the structural layer 1, the reason why the bottom of the structural layer 1 is kept exposed is to facilitate fixing . Because the bottom of the water tank is fixed vertically, it avoids the phenomenon of pipe bending, poor sealing, rain and weather resistance due to deformation due to its own gravity. Because the exposed mouth of the breathing overflow pipe 8 is at the bottom, it is difficult to dissipate heat.

Abstract

The invention relates to the field of solar utilizing devices, and particularly relates to a flat plate solar water heater and components thereof, wherein the components comprises a heat preservationbox, a water tank, a heat collecting box and a flat plate heat collector; and the flat plate solar water heater and the components thereof are designed in order to reduce the cost, simplify the structure, improve the heat preservation effect, be convenient for repairing and replacing an outer shell, and solve the problems of peripheral fixation and middle collapse of a transparent cover plate. Theheat preservation box is an extruded sheet square box with four side walls and a top or a bottom; the top and side outer shells of the water tank are extruded sheet heat preservation layer outer covers, and the bottom and the sides of the water tank liner are plastic films; the shell of the heat collecting box is an extruded sheet heat preservation layer; the outer surface of the periphery of thetransparent cover plate is adhered with a weather-proof elastic adhesive tape; the transparent cover plate is supported by a support to prevent the transparent cover plate from collapsing down; and the support comprises a horizontal supporting block and a vertical supporting block, wherein gaps with corresponding widths are respectively formed in the crossing positions of the horizontal supporting block and the vertical supporting block, the gaps are meshed with each other, the gap of the horizontal supporting block is in the upper part, and the gap of the vertical supporting block is in thelower part.

Description

technical field [0001] The invention relates to a flat solar water heater and its components in the field of solar energy utilization devices: an insulated box, a water tank, a heat collecting box and a flat plate heat collector. Background technique [0002] From "Solar Water Heaters and Systems" and "Utilization of New Energy and Renewable Energy", it can be known that flat-panel solar water heaters are composed of water tanks, upper circulation pipes, lower circulation pipes and flat-plate collectors. It is composed of a flat heat absorbing body (also known as a heat absorbing plate, commonly known as a plate core) inside it. The outer shell of the water tank is a structural layer that is stressed to be stable, and the inside of it is a thermal insulation layer and a watertight inner tank in turn. The shell of the heat collecting box is a structural layer that is stressed to be stable, the inside is a thermal insulation layer, and the top surface is a transparent cover. ...
