Operational manner, and heat exchanger device of heat exchanger device

摘要

Operational manner of the heat exchanger device of this invention, while maintaining the thermal movement magnitude to the heated liquid uniformly, prevents the scale adhesion to the heated liquid flow channel. With operational manner of this heat exchanger device, the heated liquid being heated by the heat medium body and heat exchange, after flowing out from the heated liquid flow channel, as for portion of the heated liquid, inflow into heated liquid wraparound pipe arrangement, this pulsation causes the heated liquid inflow, with the intermittent Drive operation of the wraparound pump, the heated liquid which pulsation occurs inflow into the heated liquid flow channel that way again.
