Abstract
A cooling system is disclosed including a first heat exchanger, a second heat exchanger, a means for regulating a flow of a fluid, and a thermoelectric device for cooling a fluid, wherein a difference in temperature between a hot side and a cold side of the thermoelectric device is minimized and an efficiency of the thermoelectric device is maximized.
Claims27
A cooling system comprising:
- a first heat exchanger adapted to cool a first fluid;
- a second heat exchanger in fluid communication with said first heat exchanger, wherein said second heat exchanger is operatively connected to transfer energy between the first fluid and a second fluid and to condition the second fluid to reach a desired temperature;
- a thermoelectric device disposed between and in fluid communication with said first heat exchanger and said second heat exchanger, said thermoelectric device adapted to heat the first fluid and cool the second fluid to a temperature lower than the desired temperature;
- and
- a first flow regulator adapted to circulate the first fluid through said first heat exchanger, and said second heat exchanger, and said thermoelectric device;
- wherein said second heat exchanger is configured to increase a coefficient of performance of said thermoelectric device by transferring energy between the first fluid and the second fluid.
