<p>A heat exchanger disposed in use between adjacent cells of an electrical storage battery, comprises a hollow body having a pair of sides in heat exchange relationship with walls of the cells. The sides of the hollow body define a chamber, the hollow body being provided with an inlet and an outlet for heat exchange fluid, defining a flow path. At least one of the sides including a rib 1 disposed transversely of the fluid flow path projecting into the chamber towards the opposite side to divide the chamber into a plurality of sub-chambers. The rib and the opposite side defining a slit providing communication between adjacent sub-chambers. The rib is provided with at least one projection 2 cooperating with the opposite side to resist deformation of the hollow body. Fluid-baffles (8, 9, figure 7) may also be provided. The hollow body may be made by blow moulding a plastics material. <IMAGE></p> |
