         3 . A heat exchanger core in plate design for use in a kit according to  claim 1 , for forming a heat exchanger with a plurality of plate pairs for forming first flow paths, wherein two plates each of a plate pair form the first flow path between them and a region for second flow paths is formed between adjacent plate groups. 
     
     
         4 . A heat exchanger core in plate design for use in a kit according to  claim 1 , for forming a heat exchanger with a plurality of plate groups for forming third and fourth flow paths, whereby the third flow path is formed between a first and a second plate of a plate group and the fourth flow path is formed between a second plate and a third plate of the plate group, and a region for the fifth flow path is formed between adjacent plate groups. 
     
     
         5 . The heat exchanger core according to  claim 3 , wherein at least individual plates have openings and/or cups as connecting and interconnecting regions and have channel-forming structures or embossings for forming flow paths between connecting regions. 
     
     
         6 . The heat exchanger core according to  claim 3 , wherein the first plate and second plate of the plate pair at two opposite end regions each have a connecting region as an inlet or outlet of the first flow path and a channel-forming structure between the two connecting regions to form the first flow path. 
     
     
         7 . The heat exchanger core according to  claim 3 , wherein the first plate and/or second plate of the plate pair at an end region have two connecting regions as an inlet or outlet of the first flow path and have a channel-forming structure between the two connecting regions to form the first flow path. 
     
     
         8 . The heat exchanger core according to  claim 4 , wherein the first plate, the second and third plate of the plate group at two opposite end regions have two connecting regions as an inlet or outlet of the third flow path or of the fourth flow path, wherein the first and second plate between an opposite connecting region have a channel-forming structure between one of the two connecting regions to form the third and fourth flow path, and wherein the third plate is provided between the first and second plate as a partition wall between the third and fourth flow path. 
     
     
         9 . The heat exchanger with at least two heat exchanger cores according to claim, wherein a distance of the plate pairs or the plate groups of a heat exchanger core to form the second and/or fifth flow paths is selected such that in the case of adjacent heat exchanger cores of a heat exchanger, it is the same or different, such as smaller or larger than in the adjacent heat exchanger core. 
     
     
         10 . The heat exchanger according to  claim 3 , wherein a depth of the flow channels perpendicular to the plane, defined by the plate pairs or plate groups, is selected individually for each flow channel. 
     
     
         11 . The heat exchanger according to  claim 3 , wherein plate pairs are formed from the paired arrangement of plates and with a partition wall between adjacent plates, which form pairs of flow channels, characterized in that flow through the flow channels of a plate pair is a counterflow.
