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 a flat solar water heater and components thereof including a heat insulation box, a water tank, a heat collection box and a flat plate heat collector, and belongs to the fieldof solar energy utilization devices. According to the flat solar water heater and the components thereof, the cost is reduced, the structure is simplified, the heat preservation effect is improved, the repair and replacement of a shell are facilitated, and the problems of fixation of the periphery of a transparent cover plate and collapse of the middle part of the transparent cover plate are solved. The insulation box is a square box using extruded sheets on four side walls and on a top or a bottom. The top and side shells of the water tank are extruded sheet insulation covers, and the bottomand the sides of an inner container of the water tank are plastic films. A shell of the heat collection box is an extruded sheet heat insulation layer. The outer surface of the periphery of the transparent cover plate is bonded by a weather-resistant elastic adhesive tape; the transparent cover plate is supported by a supporting frame to prevent the transparent cover plate from collapse; the supporting frame is composed of a transverse supporting block and a vertical supporting block; gaps with corresponding widths are formed in the intersections of the transverse supporting block and the vertical supporting block and are engaged with each other; the gaps of the transverse supporting blocks are formed in the upper side, and the gaps of the vertical supporting blocks are formed in the lower side.

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. ...
