Heat transfer and turbulator elements in the form of springy, ribbed, embossed or twisted strips 93 or 94 may be inserted in these passages. In the fluid inlet and outlet zones of the plates each plate may have formed therein a series of spacers 6 extending alternately from opposite faces of the plate, and being directed towards the spacers of adjacent plates to provide mutual support. By suitably profiling the plates the heat exchanging fluids may be caused to enter and leave the fluid spaces at the sides or at the ends of the plates as indicated by the arrows 80, 83. Headers (not shown) convey the fluids to or from the plate interspaces. The plate stack may be strengthened by strips 91 (Fig. 5) inserted into the gaps formed between the edges of each pair of consecutive plates and by thick plates 92 disposed at the ends of the stack. The heat exchanger may be utilized for the cooling of air prior to its liquefaction and rectification wherein four fluids may be in heat exchange viz. air, nitrogen, oxygen and a gas to be heated for use in a lowpressure turbine. In this case eight headers are required two each on the long sides and two each on the short sides of the plate stack.
