Abstract
A heat-transmitting device is adapted for use in a heat pump system which typically includes a throttle device, an evaporator, a compressor, and a further heat-transmitter device. The heat-transmitting device has a core tube coaxially disposed in a tubular shell. The region between the core tube and tubular shell is divided into two annular spaces by an annular ring sealingly disposed between the core tube and tubular shell. Each annular space serves as an independent condenser. Openings are provided in the tubular shell at each end thereof and on each side of the annular ring to facilitate fluid flow through the device. In the heat pump system, a cooling medium flows through one annular space of the device, then through the further heat transmitter, and then through the other annular space of the device. Heat is transferred by the device from the cooling medium to a fluid flowing through the core tube.
