FIELD: construction.
SUBSTANCE: fixing device (52, 90), gasket device (6, 88), plate (4) of the heat exchanger and unit (2) are offered. The fastening device is adapted to engage region (26, 28) of the edge of the heat exchanger plate (4) to secure gasket (50) to first side (8) of this plate. It comprises a first connecting element (54, 92), a second connecting element (56, 94) and a bridge (58, 96). First portion (60) of the first connecting element is adapted to engage with the gasket, and second portion (64) of the first connecting element is engaged with the jumper. First part (62) of the second connecting element is adapted to engage with the gasket, and second part (66) of the second connecting element is engaged with the jumper. The fixing device additionally contains a petal (74), located between the first and second connecting elements, with connecting part (76) of petal is engaged with the jumper, and the petal is made passing from the jumper in the direction of the gasket. The fixing device differs in that the petal has a width that varies along its length, with the length by the width of the petal is parallel to the length of jumpers, gasket device, heat exchanger plate and node.
EFFECT: increased reliability.
