| 发明名称 | Cooling circuit | ||
| 摘要 | A cooling circuit, in particular of a motor is provided that includes a drive unit with a cooling circuit, through which coolant heated in the drive unit flows, a first heat exchanger which emits heat from the coolant to the environment and a device for energy recovery with a second heat exchanger, which is switched into the cooling circuit. A line section of the cooling circuit is connectable in parallel to the second heat exchanger that includes a hydraulic element, which guides a defined coolant flow to the second heat exchanger. | ||

| 主权项 | 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. | ||
