The suspended structure of the cross plate heat exchanger is composed of corrugated plates, gaskets, fixed pressing plates, intermediate plates, movable pressing plates, brackets, upper and lower positioning guides, and compression bolts. The plate has four corner holes through which two liquids for heat transfer pass. The heat transfer plates are mounted in a frame having a fixed plate and a movable plate on one side and clamped by clamping bolts.The adjacent plates have corrugated grooves in opposite directions, and the intersections of the grooves support each other to form a contact point, and a turbulent flow is formed when the medium flows, thereby obtaining high heat transfer efficiency. The gasket is adhered to the plate to seal the flow path. The plates and compression plates are suspended from the upper guide and are positioned by the upper and lower guides, while the upper and lower guides are fixed to the posts. If one or both fluids are not a single process in the heat exchanger and multiple passes are required, the interface position will be determined to be on the fixed plate or the movable plate depending on the number of processes.
