Liquid circuit with bubble separator for a vehicle and vehicle with it

Abstract

The invention relates to a fluid circuit (1) for a vehicle, comprising at least one fluid pump for circulating heat transfer fluid in the fluid circuit (1), a first heat exchanger and a second heat exchanger, and a bubble separator (3) for separating bubbles from the heat transfer fluid, with a degassing chamber (7) and a fluid supply line (5) to the degassing chamber (7) and a fluid outlet (9) from the degassing chamber (7) integrated into the fluid circuit (1), wherein the flow cross-section in the degassing chamber (7) is larger than the flow cross-section of both the fluid supply line (5) and the fluid outlet (9), and the degassing chamber (7) projects beyond its openings (11, 13) for the fluid supply line (5) and for the fluid outlet (9).wherein a vent valve (17) for releasing gas degassed from the heat transfer fluid in the degassing chamber (7) is arranged in the upper region of the bubble separator (3) or directly above the bubble separator (3). The invention further relates to a vehicle with the fluid circuit (1) and the use of the bubble separator (3) as a microbubble separator in the fluid circuit (1) of the vehicle.
