ABSTRACT:
A heat transfer arrangement operable selectively for heating, cooling and tempering in which a heating and cooling system, and a pump are applied under predetermined flow conditions, whereby directed and substantially constant speed prevails over the entire cross-section of the flow path. The heating system with the pump and also the cooling system are located in a common tank which serves simultaneously as a collector tank for the heat carrier medium and an expansion tank of the arrangement. The heating system has several straight tube sections, running parallel to one another for an extended length, to transport the heat carrier medium. The heating system is provided with electrical heating elements in the form of rods which are inserted in the parallel straight tube sections, and leave a free flow-through cross-section. The cooling system, on the other hand, is provided with tubular cooling jackets which surround the parallel straight tube sections, leaving a free flow-through cross-section to conduct the cooling medium.
