Vehicle cooling system for a temperature-raising device and method for the cooling of a temperature-raising device

A cooling system, for a temperature-raising device of a vehicle having an air-conditioning system that serves for air-conditioning of the passenger compartment of the vehicle and that includes a refrigeration circuit, comprising:

• a cooling circuit for cooling the temperature-raising device, the cooling circuit being designed for circulating a liquid coolant for cooling the temperature-raising device;
• wherein the liquid coolant is thermally integrated via a first heat exchanger with the refrigerant of the air-conditioning system;
• wherein a part of the first heat exchanger associated with the refrigeration circuit of the air-conditioning system forms a second evaporator;
• and
• wherein the first evaporator is situated either upstream or downstream of the second evaporator.

A vehicle having a passenger compartment, comprising:

• a temperature-raising device comprising at least one of a drive battery and a fuel cell as part of the propulsion unit for the vehicle;
• an air-conditioning system that serves for air-conditioning the passenger compartment of the vehicle and that includes a refrigeration circuit that circulates refrigerant;
• and
• a cooling system for the temperature-raising device comprising a cooling circuit circulating a liquid coolant for cooling the temperature-raising device and including a first heat exchanger for exchanging heat between the coolant and the refrigerant;
• wherein the first heat exchanger is integrated into the refrigeration circuit so that during a refrigeration cycle all of the refrigerant passing through the first heat exchanger exchanges heat with air being supplied to the passenger compartment.
