Claims

- a heat transfer fluid circuit for heating and / or cooling the electrical and / or electronic elements, and preferably the passenger compartment of the vehicle, said circuit comprising a first (20) plate extending along a plane PI, said first (20) plate forming, by protuberances relative to said plane PI, first channels (26) defining a collector for the heat transfer fluid; - a refrigerant circuit comprising: • a condenser, • a compressor, • a first evaporator to cool the passenger compartment of the vehicle, • preferably a second evaporator for cooling the electrical and / or electronic elements, such that the second evaporator is thermally coupled to the heat transfer fluid circuit, said refrigerant circuit comprising a second plate (21) extending along a plane P2, said second plate (21) forming, by protuberances relative to the plane P2, second channels (25) defining a collector for the refrigerant, characterized in that it comprises a step of fixing the first (20) and the second (21) plate to an intermediate plate, located between the first (20) and the second (21) plate, the intermediate plate extending along a plane PO parallel to the planes PI and P2 and forming a closing portion for the above-mentioned first and second channels (25), in which the step of fixing the above-mentioned first plate and / or the above-mentioned second plate is carried out by welding, mechanically or chemically, preferably with the addition of at least one seal between the first (20) and second (21) plates when the fixing is mechanical or chemical.
