Abstract
An integrated high and moderate temperature cooling system both for an internal combustion engine and for auxiliary vehicle components requiring cooling. The integrated cooling system shares a coolant, yet the shared coolant is stratified to retain thermal identity between the portion of the coolant used for engine cooling and the portion of the coolant used for auxiliary vehicle components cooling. A shared coolant reservoir is used; preferably a shared heat exchanger, and optionally a common coolant pump may also be used.
Claims20
An integrated cooling system for a motor vehicle, comprising:
- at least one heat exchanger;
- a high temperature cooling subsystem;
- a moderate temperature cooling subsystem;
- a shared coolant comprising an engine coolant portion and an auxiliary coolant portion;
- a shared coolant reservoir;
- and
- piping fluidically connecting said shared coolant with each of said at least shared coolant reservoir, said high temperature cooling subsystem, said moderate temperature cooling subsystem, and said at least one heat exchanger;
- wherein said shared coolant is stratified by said at least one heat exchanger so as to thereby retain thermal identity as between the engine coolant portion and the auxiliary coolant portion thereof;
- and
- wherein the engine coolant portion of said shared coolant is utilized in said hot temperature cooling subsystem, and wherein the auxiliary coolant portion of said shared coolant is utilized in said moderate temperature cooling subsystem.
An integrated cooling system for a motor vehicle, comprising:
- at least one heat exchanger;
