Ejector pump cooling circuit comprises a compressor (11) for suctioning and compressing a coolant, a heat radiating unit (13) for removing heat from the coolant pumped from the compressor, an ejector pump (14), a first vaporizing unit (15) for vaporizing the coolant from the pump, a first bypass channel (16), a throttle unit (17) for reducing the pressure of the coolant, a second vaporizing unit (18) and an inner heat exchanger (21). The ejector pump has a nozzle section (14a) for reducing the pressure and expanding the coolant, a suction connection (14b) and a pressure increasing section (14d). Preferred Features: A high pressure coolant channel of the inner heat exchanger is arranged in the first bypass channel on the inlet side of the throttle unit. |
