COOLANT DISTRIBUTION ARRANGEMENT AND SYSTEM FOR COOLING VEHICLE PROPULSION BATTERIES

The present application relates to a coolant distribution arrangement (24, 24', 24") for a vehicle propulsion battery cooling system (8), the cooling system (8) comprising a coolant inlet circuit (16), a coolant outlet circuit (18), and at least one coolant branch (30, 37), configured to cool a set of propulsion battery packs (12, 12'), wherein the arrangement (24, 24', 24") comprises a first manifold section (22, 22', 22"), which first manifold section (22, 22', 22") comprises a coolant inlet (20, 20', 20") configured to receive coolant from the coolant inlet circuit (16), supply outlets (28, 28', 28") configured to supply coolant to the at least one coolant branch (30, 37; 30', 37'), wherein the arrangement comprises a second manifold section (32, 32', 32"), which second manifold section (32, 32', 32") comprises receiving inlets (36, 36', 36") configured to receive coolant from the at least one coolant branch (30, 37; 30', 37'), a coolant outlet (38, 38', 38") configured to return coolant to the coolant outlet circuit (18), and wherein the arrangement (24) comprises a deairing connection (44, 44', 44") between the first manifold section (22, 22', 22") and the second manifold section (32, 32', 32") configured to evacuate air from the first manifold section (22, 22', 22") to the second manifold section (32, 32', 32"). The application also relates to a vehicle propulsion battery cooling system (8) and a vehicle arranged with the system.
