The invention relates to a split solar device with a flat plate collector having a special plate core and with a dismountable built-in heat exchanger. The split solar device comprises a water tank and a collector and is characterized in that an inner container is installed in the water tank; the inner container is provided with the dismountable built-in heat exchanger of which the outer end is provided with an air outlet, a medium circulating inlet and a medium circulating outlet respectively; the collector is composed of a collector frame, a collector plate core, a back plate, a glass cover plate, a heat collection inlet and a heat collection outlet; the collector plate core is installed in the collector frame, the upper end of the collector frame is provided with the glass cover plate, the lower end of the collector is provided with the back plate, and thus a closed system is formed jointly; the heat collection inlet and a heat collection outlet penetrate through the collector frame to form a circulation loop; the collector plate core is formed by mould pressing an upper plate metal and a lower plate metal, and a main runner and a branch runner are formed between the upper plate metal and the lower plate metal. The split solar device has the advantages of indirect heat exchange, sanitary water and stable system.
Description
technical field [0001] The invention relates to the field of solar water heaters, in particular to a flat-plate heat collector with a special heat-collecting plate core and a split-type solar device with a detachable built-in heat exchanger. 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 th...
