Abstract:
1. A cooling circuit for cooling a motor of a vehicle, the cooling circuit comprising: a drive unit that is configured to facilitate a flow of a heated coolant in the cooling circuit, the heated coolant being heated in the drive unit; a first heat exchanger that is adapted to emit heat from the coolant to the environment; a device for heat recovery; a second heat exchanger, which is switched into the cooling circuit; and a line section of the cooling circuit connected in parallel to the second heat exchanger, the line section including a hydraulic element, such that the hydraulic element is connected in parallel with the second heat exchanger, wherein the hydraulic element feeds a defined coolant flow to the second heat exchanger, wherein a bypass line is provided, which seen in a flow direction of the coolant, branches in the cooling circuit before the first heat exchanger and opens after it, and wherein a thermostatic valve is arranged after the first heat exchanger which mixes coolant from the bypass line and the first heat exchanger to a temperature that is selectable.
