COOLING SYSTEM FOR COOLING COMBUSTION ENGINE AND A VEHICLE COMPRISING SAID SYSTEM

摘要

A cooling system (1) comprising: - a cooling circuit (2) for cooling a combustion engine (3) by means of coolant circulating in the cooling circuit; - a radiator (6) for cooling the coolant; - a centrifugal pump (5) for circulating the coolant in the cooling circuit; and - a swirl chamber (28) provided in the cooling circuit immediately upstream of a pump inlet (9a) of the pump. The cooling circuit comprises a first conduit (7) for conveying coolant from the radiator towards the pump inlet (9a), and a second conduit (10), via which coolant can bypass the radiator. A downstream end (29) of the first conduit and a downstream end (30) of the second conduit are tangentially connected to the swirl chamber (28) from different directions to thereby produce a swirling coolant flow in the swirl chamber and in the pump inlet (9a).
