Abstract
The device includes a heat pump integrating a refrigerant circuit taking calories from a cold source to transfer them towards a warm source. The device also includes a heat-conducting fluid/air thermal exchanger called external exchanger (30), located in the vehicle engine compartment (34), the heat-conducting fluid being either the refrigerant or a heat-conducting fluid in thermal exchange with the cold source refrigerant. The device also includes means of formation of an air flow, preferably a fan (40), circulating through the external exchanger (30) and called outlet air flow, directed from inside the engine compartment (34) to outside the vehicle. Preferably, the fan (40) shall be able to rotate in a first direction to form an air flow directed from outside the vehicle to inside the engine compartment (34) and called inlet air flow, and in a reverse direction to form the outlet air flow.
