         3 . The device for regulating the circulation of a coolant liquid for a heat exchanger according to  claim 2 , including a bypass conduit connected to said second outlet and configured so as to be connected to the outlet of the exchanger. 
     
     
         4 . The device for regulating the circulation of a coolant liquid for a heat exchanger according to  claim 1 , comprising an actuator of said distribution means, bound to a set regulation value of the flow rate and/or of the temperature of said liquid in the exchanger. 
     
     
         5 . The device for regulating the circulation of a coolant liquid for a heat exchanger according to  claim 4 , wherein said actuator is with an electric and/or pneumatic control. 
     
     
         6 . The device for regulating the circulation of a coolant liquid for a heat exchanger according to  claim 1 , including a pump for circulating the liquid. 
     
     
         7 . The device for regulating the circulation of a coolant liquid for a heat exchanger according to  claim 1 , wherein said body comprises two inlets for coolant liquids L, L′ of different temperatures in the chamber, said distribution means being configured so as to carry out in the chamber a mixing of said liquids L, L′ at a determined temperature. 
     
     
         8 . A heat exchanger comprising a device for regulating the circulation of a coolant liquid for a heat exchanger according to  claim 1 . 
     
     
         9 . The heat exchanger according to  claim 8 , including a heat exchange bundle, said bundle being configured so as to allow inflow and outflow of said coolant liquid on a same side of said bundle. 
     
     
         10 . The heat exchanger according to  claim 9 , wherein the device is configured so as to be connected to the exchanger at said same side. 
     
     
         11 . The heat exchanger according to  claim 8 , including at least two boxes, one for inflow of the liquid into the exchanger and the other one for outflow of the liquid from the exchanger, said device being configured so as to be positioned between said two boxes for inflow and outflow of liquid in the exchanger. 
     
     
         12 . The heat exchanger according to  claim 11 , wherein said device is configured so as to be integrated to said boxes. 
     
     
         13 . The heat exchanger according to  claim 11 , comprising a lid configured so as to be assembled to the bundle at said same side, said lid defining said boxes for inflow and outflow of liquid and said chamber of the regulation device. 
     
     
         14 . The heat exchanger according to  claim 8 , wherein said regulation device is dual and includes two of said chambers able to each contain a coolant liquid at a determined temperature, and the exchanger is with two stages, each of the chambers being configured for feeding one of the stages of the exchanger with one of the coolant liquids at a determined temperature. 
     
     
         15 . An air admission module comprising a heat exchanger according to  claim 8 .
