Counterflow this means that as the hot fluid enters from the right, it cools against the already warmed up cold fluid from the left. The Counterflow Plate Heat Exchangertemperature differential is nowhere near as high as at the start of the parallel heat exchanger. However, as the temperature of the warm fluids drops, it gets exposed to even colder cool fluid. Under comparable conditions, more heat is transferred in a counter-flow arrangement than in a parallel flow heat exchanger.

Working principles counterflow heat exchanger efficiency
Heat exchanger is an equipment which reduces the temperature of a medium by transferring temperature of that medium to another, when both the mediums are separated by a solid membrane or wall like structure. For efficient operation, the surface area of the wall which separates the two mediums is maximized, simultaneously minimizing the flow resistance of the fluid. Channels are formed between the plates and corner ports are arranged so that the two media flow through alternate channels. The heat is transferred through the thin plate between the channels, and complete counter current flow is created for highest possible efficiency. No intermixing of the media or leakage to the surroundings will take place as gaskets around the edges of the plates seal the unit. The corrugation of the plates provides a suitable passage between the plates, support of each plate against the adjacent one and a strong turbulence resulting in maximum heat transfer efficiency.
