Abstract

PURPOSE: To prevent an adhesion of the scale to a tube wall by providing an auxiliary pump and an exclusive valve in a tube bypassed from the upstream side of the exclusive valve of the upstream side of a main pump and communicated with the outlet port of the main pump and providing a stop valve in the connection path between the upstream side of a discharge side valve provided in a water supplying pipe and the downstream side of a main pump to inverse the flow direction of water in a heat absorption pipe.
CONSTITUTION: Normally, a valve 7 for a main pump and a discharge side valve 10 are opened while a valve 8 for an auxiliary pump and a suspension valve 9 are closed to cool a heat exchanger 4 by driving a main pump 5. When the auxiliary pump 6 is operated, a valve 8 and 9 are opened and a valve 7 and 10 are closed to reverre the flow direction in a heat absorption tube 18, provided that the pump 5 and 6 are operated at an appropriate interval of time, the attaching of scale to the heat absorption tube 18 can be prevented and a cooling efficiency is also improved.
