Abstract
A method and apparatus for active coolant volume reduction management in a pressurized reservoir coolant diverter for automobile applications. Specifically, an apparatus and method for diverting coolant flow around a pressurized coolant reservoir until the engine has reached operating temperature by employing a coolant bypass chamber and bypass shutoff valve and the like.
Claims20
An active liquid reservoir comprising:
- an inlet for receiving a liquid having a first temperature;
- an outlet;
- a first tank coupled to the inlet;
- a second tank coupled to the outlet;
- and
- a thermostat coupled to the first tank, the second tank and the outlet, for determining the first temperature and directing the fluid from the first tank to the second tank in response to the first temperature exceeding a threshold, the thermostat being further operative to direct the fluid to the outlet in response to the first temperature not exceeding the threshold.
3 more elements
An apparatus comprising:
- a coolant tank having a first chamber and a second chamber;
- an inlet coupled to the first chamber;
- an outlet coupled to the second chamber;
- a bypass coupled between the first chamber and the outlet;
- a sensor for determining a temperature of a fluid within the first chamber;
- and
- a valve for coupling the fluid within the first chamber to the bypass in response to the temperature of the fluid being below a first temperature, the valve further operative to couple the fluid within the first chamber to the second chamber in response to the temperature of the fluid being greater than the first temperature.
4 more elements
A method comprising:
- receiving a coolant having a temperature from a vehicle coolant circulation system;
- coupling the coolant to a reservoir bypass coupled to an outlet;
- determining the temperature of the coolant;
- and
- coupling the coolant to a reservoir coupled to the outlet in response to the temperature being greater than a threshold temperature.
