Definitions
- the present invention refers to a heat exchanger plate for a plate heat exchanger, comprising a heat transfer area, and an edge area, which extends around and outside the heat transfer area, wherein the heat exchanger plate is a double wall plate formed by two adjoining plates compressed to be in contact with each other.
- the invention also refers to a plate heat exchanger comprising a plurality of such heat exchanger plates arranged beside each other to define several first plate interspaces for a first medium and several second plate interspaces for a second medium.
- the object of the present invention is to provide improved detection possibilities, especially of leakage, in plate heat exchangers comprising double wall plates.
- the heat exchanger plates 1 may for instance be permanently connected to each other by means of welding, such as laser welding or electron beam welding, gluing or even brazing.
- An example of an alternative mounting of the heat exchanger plates 1 is a so called semi-welded plate heat exchanger where the heat exchanger plates 1 are welded to each other in pairs, whereby the pairs of heat exchanger plates 1 may be pressed against each other by means of tie bolts with gasket provided between the pairs.
- the plate heat exchanger may lack porthole channels, whereby the sides of the plate heat exchanger present openings to the plate interspaces 2 and 3 for the supply and discharge of the media.
- one of the plate interspaces 2, 3 may be accessible via porthole channels, whereas the other of the plate interspaces may be accessible via the side of the plate heat exchanger.
- the cavity 22 extends along the sensor probe 21 between the sensor probe 21 and the adjoining plates 1a, 1 b.
- the compressing of the adjoining plates 1 a, 1 b takes place at a high pressure so that the space remaining between the adjoining plates 1 a, 1 b is very thin, merely permitting transport or distribution of a fluid by means of capillary forces. However, such distribution will ensure that any of the primary and secondary medium entering the space between the adjoining plates 1a, 1 b will reach the cavity 22.
