Abstract
A coolant flow control management system includes an integrated pump coolant flow control and heat exchange device for delivering engine coolant to and from the engine. According to the system, coolant flows from the engine and is delivered back to the engine after passing through various coolant branches while flow is regulated by a control valve part of said device, then passes through a heat exchanger part before being returned to the engine by a pump part. Systems of the invention are particularly useful with all-electric and hybrid vehicles.
Claims22
An integrated pump coolant flow control and heat exchange device for a vehicle, the device comprising:
- (a) a pump for delivering engine coolant to an engine;
- (b) a heat exchange part which discharges the coolant from the heat exchange part toward the pump;
- and
- (c) a coolant flow control unit,
- wherein the pump and heat exchange part form an integrated unit, and
- the heat exchange part comprises an outlet for discharging coolant from the heat exchange part towards the pump, a first inlet for receiving a coolant coming from a radiator, a second inlet for receiving a coolant coming from a unit heater, and a third inlet for receiving coolant from a bypass circuit, and a heat exchanger provided inside the heat exchange part, the heat exchanger including an inlet for receiving from a source of supply a vehicle fluid and an outlet for discharging the vehicle fluid from the heat exchanger toward the supply source by which the heat exchanger is in fluid communication with the supply source.
