Abstract
A cooling system can include an evaporator for transferring heat from a heat source to a cooling fluid, a condenser for rejecting heat from the cooling fluid, a fan for inducing air flow through the condenser, a pump for pumping the cooling fluid, a controller, and a damper for selectively resisting air flow through the condenser. The controller can operate the cooling system in a pumped cooling mode when a temperature is below a threshold and reduce a speed of the fan when the temperature is below another, lower threshold. The damper can thermo-mechanically increase air flow resistance through the condenser.
Claims20
A heat exchanger comprising:
- a fluid path through the heat exchanger;
- a plurality of fins in thermal communication with the fluid path and configured to reject heat from the fluid path to air flowing across the plurality of fins;
- and
- a damper configured to resist air flow across the plurality of fins according to a temperature.
