The utility model combines the advantages of plate-fin heat exchanger and plate heat exchanger, concentrated plate heat exchanger and
The advantages of plate-fin heat exchanger：Efficiently, compact, light-weight, small, high voltage and high leakproofness, solve plate heat exchanger
The low problem of the coefficient of heat transfer in gas converting heat overcomes the shunting of plate-fin heat exchanger end enclosure structure（Or confluence）Field is non-uniform
Disadvantage, is more convenient to realize pure adverse current, high mean temperature difference, and the outlet temperature of two kinds of fluids is even up to only 1 DEG C when pure counter-flow arrangement
Difference, realize than plate-fin heat exchanger or the heat-transfer capability NTU of plate heat exchanger bigger（NTU=K.F/Wmin）Value simplifies end socket
Structure and technique save material, reduce weight and occupied space.
