The invention relates to a vehicle coolant supply device (10; 10 ') having: a traction battery coolant supply chamber (14) and a separate traction motor coolant supply chamber (16); and in the vehicle coolant supply device (10; 20 ') within the flow limiting element (10; 20 ') which fluidly connects the traction battery coolant supply chamber (14) and the traction motor coolant supply chamber (16), the flow limiting element (20; 20 ') in the partition wall (12) defines a connection channel (25; 25 ') arranged between the traction battery coolant supply chamber (14) and the traction motor coolant supply chamber (16). The flow restriction element (20, 20') provides relatively low coolant and heat exchange between the coolant supply chambers (14, 16), but allows a single common coolant expansion reservoir to be applied for all coolant circuits of the battery electric vehicle.
本发明涉及一种汽车冷却剂供应设备(10;10’),其具有:牵引电池冷却剂供应室(14)和单独的牵引电机冷却剂供应室(16);以及在汽车冷却剂供应设备(10;10’)内的流量限制元件(20;20’),该流量限制元件将牵引电池冷却剂供应室(14)和牵引电机冷却剂供应室(16)流体连接,其中,流量限制元件(20;20’)在隔离壁(12)内限定了连接通道(25;25’),该隔离壁布置在牵引电池冷却剂供应室(14)与牵引电机冷却剂供应室(16)之间。流量限制元件(20;20’)提供在冷却剂供应室(14、16)之间相对较低的冷却剂和热交换,但允许为电池电动汽车的所有冷却剂回路应用单个共用的冷却剂膨胀储液罐。
