FIELD: heat engineering.
SUBSTANCE: invention relates to heat engineering and can be used in manufacturing of heat exchangers. A heat exchanger with a collector plate (1), which contains a wall (2), in which there are passages (3), which can receive piping ends (4) of one batch, the wall (2) of collector plate (1) is made so, that for soldered or welded joint with pipes (4) forms arranged around the passages (3) end projections (5), and the wall (2) contains one facing the piping batch front wall (6) and one facing the accumulation tank rear wall (7). Each ending projection (5) extends from rectilinear base plane (8) on the rear side (7) of a wall (2), in the direction of accumulation tank.
EFFECT: technical result is improvement of characteristics of the heat exchanger with respect to thermal load.
