WIRE SPACER FOR A PLATE TYPE HEAT EXCHANGER, PLATE TYPE HEAT EXCHANGER PROVIDED WITH SUCH A WIRE SPACER, AND METHOD OF UPGRADING A HEAT CHANGER

摘要

A wire spacer (20) for separating two adjacent heat transfer plates (2, 4) of a plate type heat exchanger (1). The wire spacers 20 are formed by curved wires 22 which intersect two adjacent heat transfer plates 2 and 4 while extending along the fluid channels 6 and 8 of the heat exchanger 1 do. The wire spacers 20 include spaced apart segments 28 for maintaining a minimum vertical distance DELTA y between the heat transfer plates 2 and 4 during operation of the heat exchanger and first and second spaced- 2 support segments 24,26. The first lower support segments 24 allow the wire spacers 20 to remain fixed in their direction relative to the heat transfer plates and are spaced in a plane S1 As shown in FIG.
