摘要:
A heat storage system is provided that is capable of being manufactured at lower cost and has higher heat transmission efficiency. A heat storage system comprises a heat storage material (2) having a higher specific gravity in a solid phase than in a liquid phase, a heat storage tank (3) for containing the heat storage material, a cooling side heat exchanger (4) arranged at an upper section inside the heat storage tank and for cooling the heat storage material, a heating side heat exchanger (5) arranged at a lower section inside the heat storage tank and for heating the heat storage material, and a wall surface heater (62) for heating a side wall of the heat storage tank.

A heat storage system is provided that can reduce a decrease in heat transfer caused by a heat storage material in a solid phase. A heat storage system having a minimum heat storage temperature T min comprises a mixed salt having a non-eutectic composition, the mixed salt being configured to assume a solid-liquid coexistence state at the minimum heat storage temperature T min , the mixed salt being used as a heat storage material.

摘要:
The present invention relates to a heat exchanger including a partitioning plate and flow channels of at least two systems which are partitioned by the partitioning plate, in which the partitioning plate is made of a clad sheet having a base material made of stainless steel or a nickel-based alloy, and a clad layer having brazing properties and corrosion resistance to a corrosive fluid, an entire surface of the base material which is exposed to the flow channel of at least one system being coated by the clad layer. According to the present invention, the heat exchanger, in which the corrosive fluid flows, can be reduced in size, and the performance thereof can be enhanced. Furthermore, it is possible to simplify the manufacturing process of the heat exchanger.
