In order to ensure, in connection with welding together of the heat transferring plates from only one direction, that contact is maintained between the plates along said outer line (10B) each heat transferring plate is formed with a stiffening crease (18) outside said outer line. The stiffening crease (18) extends along the edge of plate outside said outer line (10B). |
