Abstract

PCT No. PCT/SE91/00344 Sec. 371 Date Sep. 26, 1991 Sec. 102(e) Date Sep. 26, 1991 PCT Filed May 15, 1991 PCT Pub. No. WO91/18253 PCT Pub. Date Nov. 28, 1991.In a plate heat exchanger a stack of double-wall elements (23-26) is included, which between themselves form flow passages (32-34), and each one of which comprises two heat exchange plates, each having a heat exchange portion and a sealing portion surrounding the same and via said portions abutting directly against corresponding portions of the other heat exchange plate. Sealing members (28-31) abut sealingly against adjacent double-wall elements (23-26) along the sealing portions and delimit the flow passages (32-34). Joining means press the double-wall elements against each other. To enable a quick indication of a possible leakage through a heat exchange plate at least one channel (40, 41) is arranged between the plates in each double-wall element. The channel (40, 41) is designed between opposite parts of sealing portions of the respective heat exchange plates and extends across the latter. The channel (40, 41) connects an area inside the sealing portions with the surrounding (35) of the plate heat exchanger. The rest of the sealing portions abuts directly against each other.
