Claim:
1. A data center cooling system, comprising: a cooling liquid supply conduit fluidly coupled between a cooling plant and an air-to-liquid heat exchanger positioned to receive a heated airflow from one or more racks in a data center, at least one rack supporting a plurality of heat-generating electronic devices; a cooling liquid return conduit fluidly coupled between the cooling plant and the air-to-liquid heat exchanger; and a heat transfer module comprising a thermoelectric cooling module thermally coupled to the cooling liquid supply and return conduits between the cooling plant and the air-to-liquid heat exchanger, the heat transfer module comprising a cold side and a warm side, the cold side thermally coupled to the cooling liquid supply conduit to transfer heat from a flow of a cooling liquid in the cooling liquid supply conduit to the warm side of the heat transfer module, the warm side comprising a heat sink that is thermally coupled to the cooling liquid return conduit.
