Abstract
Embodiments of the present invention provide novel techniques for cooling power conversion circuitry. In particular, a geothermal conditioning system may be used that includes a ground loop heat exchanger. The ground loop heat exchanger may pump heat from the power conversion circuitry into the ground in order to cool the power conversion circuitry. The ground loop heat exchanger may also extract heat from the ground and direct the heat into the power conversion circuitry in order to heat the power conversion circuitry. The geothermal conditioning system may also include a surface loop heat exchanger and combine the cooling and heating abilities of both the ground loop and surface loop heat exchangers in order to improve energy efficiency.
