         2 . Heat pump according to  claim 1 , wherein said control unit comprises a first heat sink suitable for dissipating heat from said control unit and housed in said second sub-chamber. 
     
     
         3 . Heat pump according to  claim 1 , wherein said second opening and said third opening are respectively located in a pair of said first parallel partitions and said second opening and said third opening are not aligned. 
     
     
         4 . Heat pump according to  claim 1 , wherein within said support structure, along a vertical direction starting from below the components are arranged in order: said third chamber, part of said second sub-chamber and said first sub-chamber. 
     
     
         5 . Heat pump according to  claim 1 , wherein said first partitions define at least a first impermeable wall suitable for separating said second chamber from said third chamber, said first impermeable wall being impermeable to gases. 
     
     
         6 . Heat pump according to  claim 5 , wherein said impermeable wall is the upper wall of said chamber. 
     
     
         7 . Heat pump according to  claim 1 , wherein said escape opening comprises a fourth opening located in one of said first partition walls. 
     
     
         8 . Heat pump according to  claim 1 , wherein at least one of said escape opening comprises auxiliary ventilation means of ATEX type. 
     
     
         9 . Heat pump according to  claim 7 , wherein said auxiliary ventilation means are placed at said fourth opening. 
     
     
         10 . Heat pump according to  claim 8 , wherein said further fourth opening is positioned on a wall opposite the wall hosting said opening. 
     
     
         11 . Heat pump comprising: a working circuit suitable for circulating a working fluid; a first heat exchanger and a second heat exchanger connected to the working circuit and suitable for exchanging heat of the working fluid, the first heat exchanger being suitable for exchanging heat with an external environment and comprising a finned structure, connected to the working circuit and ventilation means suitable for increasing the heat exchange of the external environment with the finned structure, a control unit of electronic type, configured to actuate and regulate the operation of the heat pump, a support structure suitable for supporting and containing at least part of the working circuit, the first heat exchanger and the control unit, the support structure comprising a first chamber, a second chamber and a third chamber, the chambers being reciprocally separated and being separated from the external environment by first partition walls, the finned structure and the ventilation means being contained in the first chamber, the first chamber comprising a first opening open to the external environment; the at least part of the working circuit is located in the third chamber, the third chamber includes at least one escape opening on the walls surrounding it so as to connect, in fluid passage connection, the chamber and the external environment, the escape opening being arranged in the lower part of the chamber, the second chamber comprises a first sub-chamber and a second sub-chamber, the sub-chambers being reciprocally separated by second partition walls, the first sub-chamber comprising the control unit, the second sub-chamber comprising at least a second opening on the external environment and a third opening on the first chamber so that the ventilation means force air to flow also between the second opening and the third opening through the second sub-chamber.
