Integrated temperature difference internal circulating flat heat collection plate core

The utility model relates to an integrated temperature difference internal circulating flat heat collection plate core, which realizes system simplification, ultrathin integration and ultralight structure on the premise of the high integration of pipeline functions and achieves that a heat collector has the independent running functions of a whole set of natural cycle system. Therefore, the utility model has important basis for the split wall hanging of a heat storage water tank, the construction integration of a flat water heater system, the isolation between hot water and cold water in the heat storage water tank, and mounting and azimuthal angles of a stepless regulation heat collector; the utility model is helpful for realizing the secondary circulation heating of water discharge (supply) and improving highly the technical performance and the heat efficiency of the flat water heater.
