Heat exchanger

A pure water tank for a fuel battery power generating system includes a tank body and a heat insulation mechanism arranged in the circumference of the tank body. By this heat insulation mechanism, the freezing of pure water in the tank body is prompted from the side of a bottom wall of the tank body. In the tank body, the growth of an ice gorge progresses from the side of the bottom wall toward a top wall of the tank body along its side walls and finally, the pure water freezes totally. Since the expansion of water due to its freezing is allowed in the upper space of tank body, the deformation of the side walls can be prevented. For promoting to thaw out the frozen water, a jacket is formed so as to extend from the bottom wall of the tank body to the side walls. A plurality of heat medium tubes may be provided to cross the interior of the tank body between an introductory side pipe of the jacket and an emissary side pipe of the jacket. Then, by introducing liquid heat medium into the jacket and the heat medium tubes, both peripheries and center of the ice gorge are firstly heated, so that the whole ice gorge can be thawed out in a short time.

Pure water tank for fuel battery power generating system

A heat pump type air conditioner for a vehicle has a refrigeration cycle constituted by a compressor, an external heat exchanger, a refrigerant valve unit and an internal heat exchanger unit. The refrigerant valve unit includes first and second flow control valves, and the internal heat exchanger unit includes an auxiliary internal heat exchanger and a main internal heat exchanger. In the refrigeration cycle, the first flow control valve, the auxiliary internal heat exchanger, the second flow control valve and the main internal heat exchanger are serially connected in the order of mention. The main and auxiliary internal heat exchangers change their function between an evaporator and a condenser according to the controlled state of the first and second flow control valve.
