Jet type efficient heat exchange solar heat absorption device

Abstract

The invention discloses a jet type efficient heat exchange solar heat absorption device. The jet type efficient heat exchange solar heat absorption device comprises a heat preservation layer. A solar heat absorption surface is connected to the left side of the heat preservation layer. The inner side face of the solar heat absorption surface is of a wrinkle structure. A working medium inlet and a working medium outlet are formed in the right side face of the heat preservation layer. The working medium inlet is located in the middle of the right side face of the heat preservation layer. A heat exchange core is arranged in the heat preservation layer. A working medium inlet passage hole and a plurality of working medium outlet passage holes are formed in the heat exchange core. Gaps are formed between the heat exchange core and the solar heat absorption surface as well as between the heat exchange core and the heat preservation layer. The outer surface of the jet type efficient heat exchange solar heat absorption device is wrapped with the heat preservation layer, so that the heat loss of a heat absorber is reduced; the inner side of the solar heat absorption surface is of the wrinkle structure, so that the surface roughness is improved, and the jet heat exchange performance of working media and the surface is improved; the solar heat absorption surface is movably connected with a shell of the heat exchange core through bolts, machining, installation and maintenance are all quite convenient, and the adaptability is extremely good.

Problems solved by technology

The coil heat absorber is mainly composed of metal coils, which is simple in technology, but has low thermal efficiency; the volumetric heat absorber is mainly composed of quartz glass and porous ceramics, which has high thermal efficiency, but the glass is easily broken under high temperature and high pressure conditions, and its safety and reliability are poor.

There is no jet-flow high-efficiency heat exchanger structure proposed by the present invention
