The heat exchanger of claim 1, wherein the collection area is formed within a chamber defined by walls forming the first fluid receiving member, and wherein axial flow within the first fluid receiving member of the first plurality of channels is obstructed to force the first flowstream along diagonal pathways in fluid connection with the collection area. 10. 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; anda 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. 11. The heat exchanger of claim 1, wherein the segment of the second plurality of channels that penetrates the plenum area may be altered in size or shape, or both size and shape, so as to ensure free space completely around the second plurality of channels, such that fluid is free to flow between the second plurality of channels to or from one of the first flowstream ports. 12. The heat exchanger of claim 11 wherein the areal density of the bundle of channels is greater than 400 m2/m3. 13. The heat exchanger of claim 11 wherein a heat transfer coefficient is enhanced by means of structural changes in walls of the individual channels, leading to increased turbulence in the flowing stream. 14. The heat exchanger of claim 11 wherein a cross-sectional shape of individual channels in the first plurality of channels is a hollow polygon of no more than four sides, while a cross-sectional shape of the second plurality of channels takes the form of any shape and size including the voids created between the walls of the first plurality of channels. 15. The heat exchanger of claim 11 wherein the checkerboard pattern is formed by alternating layers of sheets and rows of tubes, said tubes of which may be round, ovate or polygonal in cross section and separated laterally by void spaces, while sheets positioned above and below these rows separate them vertically, such that alternating layers of tubes are staggered. 16. The heat exchanger of claim 11 wherein a manifold at one or both ends is formed by means of obstructing axial flow of a first set of complementary channels in half-checkerboard pattern and redirecting it in the transverse direction via channels that pass diagonally between the channels of the second set of complementary channels in half-checkerboard pattern, such that flow from the first set converges to side ports alongside the ends of the channel bundle. 17. The heat exchanger of claim 1, wherein the checkerboard pattern is formed by alternating layers of sheets and rows of tubes, said tubes of which may be round, ovate or polygonal in cross section and separated laterally by void spaces, while sheets positioned above and below these rows separate them vertically, such that alternating layers of tubes are staggered.
