摘要：
A manifold 2 for a parallel flow heat exchanger (3, fig 1) comprises a first plurality of channels 5a each having an opening facing a first direction and an opening facing a second direction different from the first; a second plurality of channels 5b interleaved with the first channels and having an opening facing a third direction and an opening facing the first direction. The third direction is different from the other directions. The manifold may be 3D printed Silicon Carbide material and operate between 1070 and 1350 Celsius. The manifold may comprise a third plurality of channels and a fourth plurality of channels having an opening facing a fourth and fifth direction respectively and both have an opening facing the first direction. The fourth and fifth directions is different from the other directions. Two manifolds may be connected to opposite ends of the heat exchanger, which may comprise of a plurality of connected stacked and aligned heat exchange blocks. The heat exchanger may be housed in a refractory lined steel housing (7, fig 7). Parallel flow is intended to embrace fluids that flow parallel or anti parallel with each other (i.e. co-current (same direction) and counter-current (opposite directions)).
