       2 . Heat exchanger according to  claim 1 , wherein the channels ( 2 ,  3 ) are arranged each lying adjacent one another in rows ( 20 ,  30 ) in a plate, and on the outsides of the block of intersecting channels ( 2 ,  3 ) rows of supply and discharge pipes are formed by the throughholes ( 4 ,  5 ,  7 ,  8 ). 
   
   
       3 . Heat exchanger according to  claim 1 , wherein at least on two opposite outsides of the block of intersecting channels ( 2 ,  3 ) and on the outsides of the supply and discharge pipes ( 7 ,  8 ), in each case a row of pipes ( 6 ) is formed by throughholes in the individual films or plates (F), through which one of the fluids flows to insulate the other fluid flowing in the heat exchanger ( 1 ) against heat from the surrounding ambient. 
   
   
       4 . Heat exchanger according to  claim 1 , wherein at the upper and lower side of the stack of films or plates (F), distributor plates (F 1 -F 3 ) are arranged, through which a central supply ( 10 ) of the fluid (P; W) is divided into branch channels and guided through throughholes ( 4 ,  5 ) to the individual channels ( 2 ,  3 ) in the plates (F). 
   
   
       5 . Heat exchanger according to  claim 1 , wherein the stack of films or thin plates (F) is arranged in a housing ( 100 ) which is provided with supply and discharge pipes for the two fluids (W, P). 
   
   
       6 . Heat exchanger according to  claim 1 , wherein a plurality of heat exchangers ( 1 ) is combined into a group in a block and each individual heat exchanger ( 1 ) is supplied separately with the two fluids (W, P), the fluid being distributed from a common supply pipe to the individual heat exchangers ( 1 ) and discharged through a common discharge pipe. 
   
   
       7 . Heat exchanger according to  claim 1 , wherein the films or plates (F) are made of material which is sufficiently inert in relation to the fluids. 
   
   
       8 . Heat exchanger according to  claim 2 , wherein at least on two opposite outsides of the block of intersecting channels ( 2 ,  3 ) and on the outsides of the supply and discharge pipes ( 7 ,  8 ), in each case a row of pipes ( 6 ) is formed by throughholes in the individual films or plates (F), through which one of the fluids flows to insulate the other fluid flowing in the heat exchanger ( 1 ) against heat from the surrounding ambient.
