HEAT EXCHANGER WITH HEAT EXCHANGING UNIT

摘要

There is provided a heat exchanger apparatus comprising a plurality of mutually identical heat exchanger coils. Each coil has the shape of a cup. The coils are placed in close relationship on both sides of a base plate which blocks a flow channel. The base plate exhibits a plurality of orifices, and a coil is placed over each orifice with its rim in contact with the base plate and surrounding the edge of the orifice, but only one coil is assigned to each orifice. Adjacent coils on opposite sides of the base plate are stagger so that their rims overlap each other without covering any part of the orifice assigned to the adjacent coil on the opposite side of the base plate.
