Flat-plate paraboloidal solar light-condensing and heat-collecting device

Abstract

The invention relates to a flat-plate paraboloidal solar light-condensing and heat-collecting device, and belongs to the technical field of solar heat utilization. The flat-plate paraboloidal solar light-condensing and heat-collecting device is particularly suitable for the integration of solar energy and buildings, and provides a multifunctional technology-integration high-efficiency heat-condensing device with more application value for the 'South Wall Plan' and the 'Roof Plan'. The flat-plate paraboloidal solar light-condensing and heat-collecting device comprises a light-transmitting and sealing component and a heat-collecting and light-condensing component two big parts, wherein the light-transmitting and sealing component consists of a box body, a bottom plate, a T-shaped fixed strip, a light-transmitting cover plate, a thermal-insulation and heat-preservation coating, a sealant, a vacuumizing head, a working medium inlet, a working medium outlet, a mounting block and an adsorbent storage strip; the light-transmitting cover plate is combined with the T-shaped fixed strip by using the sealant; the combined light-transmitting cover plate and the T-shaped strip are downwards embedded into a groove on the box body; and the heat-collecting and light-condensing component comprises a working medium passage pipe, a heat-absorbing plate, a heat sink strip, a heat-absorbing coating, a paraboloidal light-condensing reflection plate, a light-condensing plate reinforcing rib, a passage pipe joint, a U-shaped connecting bend, a G-spot groove, a thermal-insulation and heat-preservation coating, a fixing plate and a shockproof block.

Description

technical field [0001] The invention relates to a flat-plate parabolic solar energy concentrating and heat-collecting device, which belongs to the technical field of solar thermal utilization. It is especially suitable for the integration of solar energy and buildings, and provides a multifunctional technology integrated high-efficiency heat collection device with more application value for the "south wall plan" and "roof plan". Background technique [0002] With the massive consumption of fossil energy such as oil, coal, and natural gas currently used by humans, it is becoming increasingly scarce, which leads to global warming and serious ecological and environmental problems. People's development and utilization of new energy and renewable energy, will become very urgent. The energy of solar energy is huge, and the total radiant energy reaching the ground every second is as high as 600,000 KW, which is equivalent to more than 50,000 times the current total power generatio...

Problems solved by technology

However, the energy of several times the density is not used to directly heat most of the heat collecting tubes, but needs to be reheated through secondary conduction, and the high-temperature heat absorbing plate and light-standing plate are inevitably lost in the conduction process. A large amount of heat energy; moreover, although this utility model has used double-layer cover and insulation layer, because described peripheral wall is directly made of metal material, does not see adding any insulation measure on outer wall, there is serious insulation problem in this design. problem, so the space for the temperature rise of the working fluid will be greatly reduced

[0005] After further investigation of the market, most of the existing flat solar water heaters have problems such as low solar energy utilization rate, low heat collection temperature, and poor sealing of components. In addition, the cost is extremely high, and it is difficult for them to enter the building integration technology and market key
