Abstract
A cryogenic heat exchanger, such as a pulse tube cryogenic heat exchanger, is provided wherein the chilled heat transfer connection point can be conveniently disposed at an 'apex.' The heat exchanger has a bridging chamber with a first opening and a second opening. Disposed within the bridging chamber is a plurality of fins disposed longitudinally between the first opening and the second opening so as to partition the bridging chamber into a plurality of parallel longitudinal channels of equal cross-section. The first opening and the second opening are disposed at an angle to one another, so that a heat transfer gas flowing through the heat exchanger, changes direction within the bridging chamber.
