A plate type heat exchanger is provided with a permeable container in the inlet manifold formed by aligned holes in the plates. The container collects solid materials entrained in the feed liquid and may be withdrawn for emptying or replacement when full. The solids which may need to be removed before the liquid enters the heat exchanger flow passages include detached pipe line scale and live material grown in the pipework. The container may be open-topped or of closed section and means may be provided for spacing it from the edges of the holes forming the manifold.
