Plate for heat exchange arrangement and heat exchange arrangement

A plate for a heat exchange arrangement for the exchange of heat between a first and a second medium, comprising:

• a first heat transferring surface arranged in use to be in contact with the first medium and a second heat transferring surface arranged in use to be in contact with the second medium;
• an inlet porthole for the first medium at a first end of the first heat transferring surface;
• an inlet porthole for the second medium;
• and
• an outlet porthole for the first medium at a second end of the first heat transferring surface, the first end spaced from the second end in a first direction,
• wherein the first heat transferring surface comprises at least one ridge arranged to divide said first heat transferring surface into at least a first region in direct thermal contact with the inlet porthole for the second medium, and a second region not in direct thermal contact with the inlet porthole for the second medium, and
• wherein the inlet porthole for the first medium is arranged in said first region,
• wherein the outlet porthole for the first medium is arranged in the second region,
• wherein the first region has an outlet,
• wherein a transfer channel conveys the first medium from the first region to the second region, the transfer channel having an inlet connected to and extending from the outlet of the first region in the first direction toward the inlet porthole for the first medium.
