Abstract
An electronics control system includes a power control unit disposed above a graphics processing unit and thermally connected to a cooling assembly inside. The system also includes a graphics processing unit disposed below the power control unit and thermally connected to the cooling assembly, an auxiliary DC-DC converter disposed below the power control unit and thermally connected to the cooling assembly, and a cooling assembly disposed at a predetermined location and configured to simultaneously transfer heat away from a power control unit, graphics processing unit, and auxiliary DC-DC converter via fluid circulation are presented.
Claims8
An electronics control system, comprising:
- a cooling assembly;
- a power controller thermally connected to a first side of the cooling assembly via a thermal interface material;
- a processor thermally connected to a second side of the cooling assembly opposite the first side, the processor and the power controller are separated by at least one thermal spacer;
- and
- an auxiliary DC-DC converter thermally connected to each of the cooling assembly and the processor, and the auxiliary DC-DC converter disposed between the cooling assembly and the processor, wherein
- the cooling assembly is to simultaneously transfer heat away from the power controller and the processor, and
- the auxiliary DC-DC converter and the cooling assembly are separated by the at least one thermal spacer, and the auxiliary DC-DC converter and the processor are separated by at least one heat sink thermally connected to the processor.
