Abstract
The high cost of fabricating heat exchangers having two fluid flow paths in countercurrent or cross current relation is minimized by utilizing an extrusion (14) wound upon itself with adjacent convolutions (16, 18, 20, 24) spaced at (26) and located within a housing (10). A baffle (56) or a seal (82, 84) are employed within the housing (10) to respectively define cross current or countercurrent heat exchangers. Alternatively, an extrusion such as a unitary extrusion (100) may contain plural flow paths (114, 120, 122) or an extrusion made up of two extrusions (150, 152) bonded together and having flow paths (162, 164) may be employed.
