摘要： A plate heat exchanger comprises a plurality of heat exchanger plates (1) formed of a metal sheet and permanently joined to each other by means of a braze material to form a plate package having first plate inter spaces (4) and second plate inter spaces (5). Each heat exchanger plate has a pattern forming a heat transfer area and a plurality of porthole areas. Each heat exchanger plate extends along a main extension plane (p). The areas extend, on one side of the heat exchanger plate, between a primary level (p') at a distance from the main extension plane and a secondary level (p') at a distance from and on an opposite side of the main extension plane. Each heat exchanger plate has a depth (d) defined by the distance between the primary level and the secondary level. The depth is equal to or less than 1,0 mm.

摘要： A plate heat exchanger comprises a plurality of heat exchanger plates joined to each other. Each plate (1) has a heat transfer area (20), a first porthole area (21), a second porthole area (22), a third porthole area (23) and a fourth porthole area (24). Each porthole area surrounds a porthole having a porthole edge (25). Each porthole area comprises an annular flat area (31), a set of inner portions (32) on the annular flat area along the porthole edge (25), and a set of outer portions (33) along the annular flat area (31) at a distance from the inner portions. The outer portions of the first porthole area have a first relative peripheral position with respect to the inner portions. The outer portions of the fourth porthole area have a second relative peripheral position with respect to the inner portions. The first relative peripheral position includes a peripheral displacement in relation to the second relative peripheral position.

摘要： A plate heat exchanger comprises a plurality of heat exchanger plates (1). The plates are provided beside each other and permanently joined to each other to form a plate package having first plate interspaces and second plate interspaces. Each plate has a heat transfer area (20) and four porthole areas (21-24) defined by a porthole edge (25). Each of the porthole areas comprises an annular flat area (31) located at one of a primary and secondary level, and a set of inner portions (32) on the annular flat area at the other of the primary and secondary level. Each inner portion has an inner part adjoining the porthole edge and an outer segment adjoining the inner part and having an angular extension of at least 180°. The outer segment has a continuous contour and a radius R, which is allowed to vary within the range 0,8R ≤ R ≤ 1,2R.

摘要： A plate heat exchanger comprises a plurality of heat exchanger plates (1), a first end plate (2) and a second end plate (3). The plates (1-3) are permanently joined to each other by means of a braze material. Each heat exchanger plate has a heat transfer area and a plurality of porthole areas surrounding a respective porthole. The plate heat exchanger comprises a plurality of (50, 53) having a bottom surface (51) turned towards the heat exchanger plates. At least one of the flat elements comprises an annular protrusion (52) extending from the bottom surface (51) and tightly abutting one of the porthole areas of the outermost heat exchanger plate.
