Abstract (en)

A plate heat exchanger comprises a stack (10) of rectangular heat transfer plates (1), wherein each rectangular heat transfer plate (1) comprises a circumference with four circumference edges (21) arranged at the circumference of the rectangular heat transfer plate (1), a rectangular heat transfer wall (2) extending between the circumference edges (21) of the heat transfer plate (1), the rectangular heat transfer wall (21) defining a plane and comprising a circumference portion (22) extending to the circumference edge (21) in the plane of the heat transfer wall (2), and the heat transfer plate (1) further comprises at least two folded parts (3) arranged at the circumference of the heat transfer plate (1) and extending from the heat transfer wall (2) over the circumference edge (21) of the heat transfer plate (1), the folded parts (3) contacting the heat transfer wall (2) for forming spacer elements. Two opposite folded parts (4) are folded towards a same side of the plane of the rectangular heat transfer wall (2), or at least two adjacent folded parts (4) of the rectangular heat transfer wall (2) are each folded towards opposite sides of the plane of the rectangular heat transfer wall (2) with respect to the adjacent folded part (3). Pairs of heat transfer plates (1) are arranged so that each folded part (4) of one heat transfer plate (1) is in contact over the entire length of the corresponding circumference edge (21) either with a folded part (4) of an adjacent heat transfer plate (1) or with a circumference portion (22) of the heat transfer wall (2) of an adjacent heat transfer plate (1).
