The invention relates to a split solar device with a stainless steel plate core heat collector and an outer-covering inner container end heat exchanger. The split solar device comprises a water tank and the heat collector and is characterized in that an inner container is arranged in the water tank, one end of the inner container and an outer-covering end inner container form the heat exchanger, and an exhaust port, a medium circulation inlet and a medium circulation outlet are formed in the outer end of the heat exchanger; the heat collector is composed of a heat collector frame, a heat collection plate core, a back plate, a glass cover plate, a heat collection inlet and a heat collection outlet; the heat collection plate core is arranged in the heat collector frame, the glass cover plate is arranged at the upper end of the heat collector frame, the back plate is arranged at the lower end of the heat collector frame, and the heat collection inlet and the heat collection outlet are connected with the medium circulation inlet and the medium circulation outlet of the water tank respectively; the heat collection plate core is formed by pressing an upper metal plate and a lower metal plate through a die, and a main flow channel and a branch flow channel are formed between the upper metal plate and the lower metal plate; the upper metal plate is coated by a selective absorption film layer and transmits heat to fluid in the heat collection plate core, and heat transmission is achieved through fluid circulation.
Description
technical field [0001] The invention relates to the field of solar water heaters, in particular to a split solar device comprising a stainless steel plate-core heat collector and a heat exchanger at the end of an outer inner tank. Background technique [0002] At present, most of the split solar water heaters 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, which has corrosion problems, and eventually the heat exchanger is damaged, resulting in the scrapping of the entire water tank; the external heat exchanger has a large heat exchange area, 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 and the inside of...
