The spiral tube water tank heat exchanger is used as the core of the whole system, and has very important effect on improving the heat exchange capacity of the system.
For a traditional spiral tube water tank heat exchanger, an inflow pipe of the traditional spiral tube water tank heat exchanger usually adopts a simple straight-through mode and horizontally extends into an inner container of a water tank from the position of the axis of the water tank. The structure causes that the fluid flows into the water tank and then reaches the wall surface of the inner container, and then is divided vertically, so that the temperature field inside the water tank is not uniformly distributed, and the whole heat exchange effect of the water tank is influenced. The position of the outlet pipe of the traditional spiral pipe water tank heat exchanger is determined by combining the aesthetic requirements according to the opening position of the inlet pipe, and one inlet pipe corresponds to one outlet pipe. Because two heat source spiral pipe water tank heat exchangers need to select different operation modes according to meteorological change and load side demand are nimble in the use, and the play flow pipe that has the selectivity can match different operation modes better, and then promotes the efficiency of water tank heat exchanger heat transfer.
