CPC classification number: B60H1/00571 , B60K11/04
Abstract: Disclosed is a cooling system comprising a cooling circuit with a deaeration device arranged in the cooling circuit for separation of air bubbles from coolant circulating therein. The deaeration device comprises a deaeration chamber having a coolant inlet connected to a feed pipe of the cooling circuit, a first coolant outlet connected to a coolant pump of the cooling circuit, and a second coolant outlet connected to an expansion tank via a static line. The deaeration chamber has a larger cross-sectional dimension than said feed pipe. The second coolant outlet is located in such a position in relation to the coolant inlet and the first coolant outlet that the coolant flow in the deaeration chamber between the coolant inlet and the first coolant outlet will move migrating air bubbles in the longitudinal direction of the deaeration chamber towards the second coolant outlet.

Abstract: Disclosed is a cooling system comprising: a first cooling circuit with a first coolant pump; a second cooling circuit with a second coolant pump; an expansion tank provided with an expansion chamber for accumulation of coolant, wherein the expansion chamber is connected to the second cooling circuit to allow the expansion chamber to receive coolant from the second cooling circuit; and a deaeration device arranged in the first cooling circuit for separation of air bubbles from the coolant circulating therein. The deaeration device is located at a lower position than the expansion tank and connected to said expansion chamber via a static line to allow air bubbles separated from the coolant in the deaeration device to migrate upwards in the static line towards the expansion chamber.

Abstract: A temperature control system for a vehicle, comprising a main circuit comprising a tubing in which there is provided a coolant, a main circuit pump configured to pump said coolant through the tubing in a first direction. Connected in parallel to the main circuit are first and second sub-circuits for cooling or heating of components connected thereto. In the sub-circuits there are provided first and second pumps that pump coolant through said sub-circuits from a first end to second end at which the respective sub-circuit is connected the main circuit. The first end is upstream the second end as seen in the first direction in the first circuit, and the first end of the first sub-circuit and the first end of the at least one second sub-circuit are joined to a common tubing section which in its turn is connected to the tubing of the main circuit.
