An electronics equipment heat exchanger system for thermally managing the electronic devices of a computer server and the exhaust air emitted from the computer server. The electronics equipment heat exchanger system generally includes a heat exchanger attached near an air outlet of a support unit for a support rack, a thermal management unit fluidly connected to the heat exchanger, and a thermal conditioning unit fluidly connected to the thermal management unit and the heat exchanger. The thermal management unit directly thermally manages one or more electronic devices of the server mainboard while the heat exchanger thermally manages the exhaust air before the exhaust air exits through the outlet of the support unit of the computer server.
