Temperature control systems and methods

A system for controlling the temperature of an electrical submersible pump variable speed drive system, comprising:

• a housing associated with heat producing equipment;
• a heat sink system in thermal association with the heat producing equipment to passively dissipate heat from the variable speed drive system;
• a thermoelectric assembly in thermal association with the heat producing equipment to actively transfer heat to or from the variable speed drive system;
• a power control system operatively connected to the thermoelectric assembly for activating the thermoelectric assembly to obtain a predetermined temperature of the variable speed drive system;
• and
• a sensor operatively connected to the power control system to provide an input to the power control system indicative of the temperature of the variable speed drive system and for sensing the temperature of the variable speed drive system.

A method of controlling the temperature of an electrical device, which comprises:

• determining the temperature of the air surrounding the electrical device;
• passively dissipating heat produced by the electrical device through a heat sink system in thermal association with heat producing equipment;
• and
• actively transferring heat to or from the electrical device through a thermoelectric assembly in thermal association with the heat producing equipment.
