Abstract
Counter-flow heat exchanger is constructed with plenums at either end that separate the opposing fluids, the channels of which are arrayed in a checkerboard patterns, such that any given channel is surrounded by channels of opposing streams on four sides—laterally on both sides and vertically above and below.
Claims17
A countercurrent flow single pass heat exchanger comprising:
- a bundle of channels comprising a first plurality of channels and a second plurality of channels, individual channels of the first plurality being arranged with respect to individual channels of the second plurality to form a checkerboard pattern substantially through a transversal cross-section of the bundle;
- the individual channels of the first plurality of channels being in fluid communication with first flowstream ports and individual channels of the second plurality of channels being in fluid communication with second flowstream ports, wherein the first flowstream ports are distinct from and not in fluid communication with the second flowstream ports;
- a first fluid receiving member;
- and
- a second fluid receiving member, the first fluid receiving member, the second fluid receiving member and the bundle of channels being arranged such that the first fluid receiving member is positioned between the second fluid receiving member and an end of the bundle;
- and wherein the second plurality of channels extends pass the end of the bundle and through the first fluid receiving member;
- the first plurality of channels extends through the bundle and is in fluid communication with a collection area of the first fluid receiving member, the collection area being fluidly connected to at least one of the first flowstream ports.

A countercurrent flow single pass heat exchanger comprising:
- a bundle of channels comprising a first plurality of channels and a second plurality of channels, individual channels of the first plurality of channels being in fluid communication with first flowstream ports and individual channels of the second plurality of channels being in fluid communication with second flowstream ports, the first flowstream ports being distinct from and not in fluid communication with the second flowstream ports;
- wherein the individual channels of the first plurality are arranged with respect to the individual channels of the second plurality to exchange heat within an interior region of the bundle along a longitudinal axis of the bundle in four directions with respect to each channel without mixing the first and second streams, the four directions comprising above a selected channel in the interior region, below the selected channel, and along at least a portion of each lateral side of the selected channel;
- a first fluid receiving member;
- and
- a second fluid receiving member, the first fluid receiving member, the second fluid receiving member and the bundle of channels being arranged such that the first fluid receiving member is positioned between the second fluid receiving member and an end of the bundle;
- and wherein the second plurality of channels extends pass the end of the bundle and through the first fluid receiving member;
- the first plurality of channels extends through the bundle and is in fluid communication with a collection area of the first fluid receiving member, the collection area being fluidly connected to at least one of the first flowstream ports.
