Abstract
The present invention relates to a plate heat exchanger comprising several heat exchange plates arranged in a frame between a frame plate and a pressure plate, and suspended from a horizontal carrying bar, which has a hollow supporting body with protruding suspension means on its underside for the heat exchange plates. According to the invention the supporting body and the suspension means are formed of a bent sheet material, and the carrying bar has opposite side walls (3, 15, 16) which extend to abutment against each other and are joined to each other at least at lower support surfaces (6) located close to a vertical center plane through the carrying bar, and which beneath said support surfaces (6) extend away from said central plane to form said suspension means.
