Abstract
The present disclosure relates to a multiple zone vehicle radiator, including: a housing; a first zone included in the housing; a second zone included in the housing; a baffle between the first and second zone, located in an outlet manifold of the housing; and a zone modifier configured to regulate coolant distribution between the first zone and second zone according to predetermined conditions.
Claims16
A thermal management system for a vehicle having a combustion engine and a transmission cooler, comprising:
- a multiple-zone radiator having an inlet manifold with a single inlet configured to receive a coolant from the engine and having an outlet manifold divided by a baffle, wherein the radiator is configured to deliver coolant from a first zone to a first outlet and from a second zone to a second outlet;
- a thermostat having an inlet receiving an unobstructed flow from the first outlet and having an outlet configured to regulate coolant flow to the engine according to an open or closed position of the thermostat;
- a three-way valve having a valve inlet connected to the second outlet and configured to selectably couple the second outlet to either the transmission cooler or the inlet of the thermostat;
- and
- a zone modifier coupled between the first and second outlets of the radiator and configured to distribute coolant from the first zone and to the valve inlet in response to a coolant pressure being greater at the first outlet than at the second outlet when the thermostat is in the closed position and the three-way valve couples the second outlet to the transmission cooler.

- a jumper line between outlet lines of the first and second outlets of the radiator;
- a thermostat having an inlet receiving an unobstructed flow from the first outlet and having an outlet configured to regulate coolant flow to the engine according to an open or closed position of the thermostat;
- a three-way valve having a valve inlet connected to the second outlet and configured to selectably couple the second outlet to either the transmission cooler or the inlet of the thermostat;
- and
- a zone modifier in the jumper line configured to distribute coolant from the first zone to the valve inlet in response to a coolant pressure being greater at the first outlet than at the second outlet when the thermostat is in the closed position and the three-way valve couples the second outlet to the transmission cooler.
