Abstract

A heat exchanger is formed by selectively stacking an appropriate number of functionally independent and discrete heat exchange panels, each of which is a complete heat exchanger in its own right with a set of vanes and two flow passages in indirect heat exchange relationship through said vanes.

Claims

1. A heat exchanger for exchanging heat between a first fluid and a second fluid, at least one of the fluids being a gas, the exchanger comprising:

a plurality of identical panels each formed by

a set of substantially parallel vanes, and

a serpentine tube having a pair of ends and traversing the respective set of vanes and fixing same together parallel to one another to define a plurality of parallel flow passages crossing the tube and having oppositely opening passage ends, the panels being arrayed laterally atop one another in a stack with the passages parallel;

respective sheets between and laterally engaging the vanes of adjacent panels in the stack, whereby each passage is delimited by a respective two of the vanes and a respective two of the sheets;

means releasably fixing the vanes and sheets together with the panels in the stack and all the passages extending parallel to one another;

a respective tube valve at each end of each tube;

first manifold means connected to the ends of the passages for passing the first fluid therethrough; and

second manifold means connected via the tube valves to the ends of the tubes for passing the second fluid therethrough countercurrent to the first fluid.

2. The heat exchanger defined in claim 1 wherein each vane has a height measured perpendicular to the respective sheets which is a multiple of the spacing between adjacent vanes of the same panel.

3. The heat exchanger defined in claim 1 wherein each panel has two edge vanes formed with outwardly bent lips lying on the respective sheets, the fixing means including clips engaging the bent lips to opposite sides of the respective sheets.

4. The heat exchanger defined in claim 1, further comprising:

a respective passage valve at each end of each passage.
