Split solar device comprising heat-pipe heat collector and detachable heat exchanger

Abstract

The invention relates to a split solar device comprising a heat-pipe heat collector and a detachable heat exchanger. The split solar device comprises a water tank and the heat-pipe heat collector. The split solar device is characterized in that an inner container is mounted in the water tank, the detachable heat exchanger is mounted in the inner container, the outer end of the detachable heat exchanger is provided with an exhaust port, a medium circulation inlet and a medium circulation outlet respectively, and the medium circulation inlet and the medium circulation outlet respectively penetrate through the outer wall of the water tank and are connected with a medium circulation pipeline. The heat-pipe heat collector is composed of a combining collection box, heat collection pipes and a tail bracket. A combining collection pipe penetrates through the inside of the combining collection box, wherein two ends of the combining collection pipe are connected with a medium heat collection outlet and a medium heat collection inlet respectively. The heat collection pipes are evenly distributed at intervals in the middle of the combining collection pipe. The condensation ends of heat collection core pipes inside the heat collection pipes are inserted in the combining collection pipe, and the other ends of the heat collection core pipes are provided with heat absorption fins. The medium heat collection outlet and the medium heat collection inlet are connected with the medium circulation inlet and the medium circulation outlet of the water tank through the medium circulation pipeline to form a circulation loop. According to the split solar device comprising the heat-pipe heat collector and the detachable heat exchanger, the distance between the medium circulation inlet and the medium circulation outlet is extended, the temperature difference of media in the heat collection pipes is increased, and the circulation rate and the heat exchange efficiency of heat exchange media are improved.

Description

technical field [0001] The invention relates to the field of solar water heaters, in particular to a split solar energy of a heat pipe type heat collector and a detachable heat exchanger. Background technique [0002] At present, split solar water heaters all adopt a pressure-bearing structure, and the heat exchange structure is divided into built-in heat exchange and external heat exchange. The built-in heat exchanger is a stainless steel heat exchanger with high heat exchange efficiency, but it is usually made of stainless steel welding and has corrosion problems, which greatly reduces the service life of the water tank, and eventually the heat exchanger is damaged, resulting in the scrapping of the entire water tank; external heat exchange The water tank has a large heat exchange area, and the heat exchanger does not bear external pressure, but the heat exchange medium will also cause corrosion to the interlayer heat exchanger formed on the outside of the water tank liner...

AI Technical Summary

Problems solved by technology

U-shaped tube collectors have insufficient heat absorption due to the small external area of ​​the U-shaped tubes, resulting in heat loss in the vacuum tubes and a low overall heat collection efficiency; vacuum tube collectors have high heat collection efficiency, but as the service life increases, the vacuum The heat collection efficiency is insufficient, and the damage of individual heat collection tubes will affect the operation of the entire collector; the heat loss of the flat plate collector is large and it is not suitable for cold regions, and the overall thermal efficiency is not high
