METHOD OF MAKING A PLATE PACKAGE FOR A PLATE HEAT EXCHANGER

摘要

A plate package made according to the method includes first heat exchanger plates and second heat exchanger plates. Each heat exchanger plate has a first porthole, and the port hole of at least one of the heat exchanger plates is surrounded by a peripheral rim. The first heat exchanger plates and the second heat exchanger plates, are joined to each other and arranged side by side in such a way that the peripheral rims together define an inlet channel extending through the plate package. The peripheral rim of the first and/or the second heat exchanger plates has at least one through hole, forming a fluid passage allowing a communication between the inlet channel and the first plate interspaces. The at least one through hole is made in a condition in which the first and the second heat exchanger plates have been joined to each other to form the plate package.

1. A method of making a plate package for a plate heat exchanger, the method comprising the steps
of providing a number of first heat exchanger plates and a number of second heat exchanger plates, each heat exchanger plate having a first porthole, wherein said port hole of at least one of the heat exchanger plates is surrounded by a peripheral rim, arranging the first heat exchanger plates and the second heat exchanger plates side by side in an alternating order in which, the peripheral rims together define an inlet channel extending through the first and the second heat exchanger plates, joining said first and second heat exchanger plates with each other to form the plate package, and making, in a condition in which the first and the second heat exchanger plates have been joined to each other, at least one through hole in the peripheral rims of the first and/or the second heat exchanger plates.
