Problems solved by technology

In the heating circulation system, water is used as the medium to transmit heat, and there is a certain heat loss in the process of heat transmission. At the same time, the ordinary radiator heating method requires a high temperature of the water, and the solar water heating system is to prevent scaling. The temperature of the water should not be too high. Practical technical problems, but also requires investment in water tanks, pipelines, control, storage tanks, etc. Large investment is not conducive to the promotion and utilization of solar heating

Embodiment 1

[0038] like figure 1 — Figure 7 , a solar heat collector, including a plurality of heat-absorbing radiators 1 arranged side by side, a single heat-absorbing radiator 1 is a triangular tubular structure and forms a triangular air circulation channel 101, and a single heat-absorbing radiator 1 absorbs heat from a metal substrate The material is processed and shaped. The outer surface of one side of the heat-absorbing and cooling body 1 is a heat-absorbing surface 102 for absorbing solar energy. There is a high-efficiency heat-absorbing material on the heat-absorbing surface 102. Heat exchange, the heat-absorbing surface 102 of heat-absorbing heat-radiating body 1 is plane like this, and the part of the back that is in contact with air for heat exchange is a triangular tubular structure. The contact area is small, and the heat dissipation area is 6-7 times that of the heat absorption area, which improves the heat exchange efficiency. The air flows from one end of the triangula...

Embodiment 2

[0043] like Figure 8 — Figure 10 As shown, a solar air heat collector includes a solar air heat collector 4, an air inlet duct 10, an air outlet duct 9 and a two-way exhaust fan 12, and the solar air heat collector 4 includes a transparent cover plate 6, a back plate 7 and a An annular metal frame 5, one side of the metal frame 5 is fixed with a transparent cover plate 6, the other side of the metal frame 5 is fixed with a back plate 7, a closed container is formed between the transparent cover plate 6, the back plate 7 and the metal frame 5, A plurality of heat-absorbing and radiating bodies 1 arranged side by side are installed in the airtight container. A single heat-absorbing and radiating body 1 has a triangular tubular structure and forms a triangular air circulation channel 101. A single heat-absorbing and radiating body 1 is processed by a heat-absorbing material of a metal substrate. Shaped, the outer surface of one side corresponding to the transparent cover plate...

Embodiment 3

[0048] like Figure 11 As shown, an air heat collecting device, the difference between the present embodiment and the second embodiment is that a second air outlet is provided at the bottom of the box body of the two-way exhaust fan 12, and the first PTC ceramic electric heating is installed in sequence at the second air outlet. Plate 15 and the third one-way exhaust valve 16, when the two-way exhaust fan 12 reversely blows air, the second one-way exhaust valve 11 is closed, and the third one-way exhaust valve 16 is opened, when there is the sun but the light intensity is not enough , such as the morning, afternoon, cloudy, rainy or snowy days and other situations, the first PTC ceramic electric heating plate 15 can assist heating.

Abstract

The invention discloses a solar heat utilization device or equipment, and particularly discloses a solar heat collector with a triangular tubular heat radiation structure. The solar heat collector comprises a plurality of heat absorbing and radiating bodies arranged in parallel, wherein a single heat absorbing and radiating body is in a triangular tubular structure; the external surfaces of one sides of the heat absorbing and radiating bodies are heat absorbing surfaces for absorbing solar energy; heat absorbing materials are arranged on the heat absorbing surfaces; the inner tube walls and the outer tube walls of the heat absorbing and radiating bodies all can exchange heat, so that the contact area between the solar heat collector and circulating air is increased because the inner tube walls and the outer tube walls of the heat absorbing and radiating bodies all can exchange heat; the triangular tubular heat collector for absorbing heat and radiating heat is used for directly heating air in buildings by mainly using solar energy to supply heat to rooms in winters and providing assistance to heat supply by using power in cloudy days, rainy days and snowy days; and as water circulating inlet and outlet are reserved in a solar heating plate, the hot water can be heated when the heating is not needed by the buildings in summer, so that the domestic use of hot water is solved for families and no investment waste is taken.

Description

technical field [0001] The invention relates to a solar heat utilization device or equipment, in particular to a solar heat collector with a triangular tubular heat dissipation structure. Background technique [0002] At present, the products utilizing solar thermal energy mainly include solar water heaters. Solar air collectors are in their infancy. Both solar water heaters and solar hot water heating systems use solar energy to heat water, use the heated hot water directly, or circulate hot water to the room to heat the room. In the heating circulation system, water is used as a medium to transmit heat, and there is a certain amount of heat loss. At the same time, the ordinary radiator heating method requires a high temperature of the water, but in order to prevent scaling in the solar water heating system, the temperature of the water should not be too high. Practical technical problems also require investment in water tanks, pipelines, control, storage tanks, etc., and...
