Integrated PCU and GPU cooling system
View Patent ↗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.
1. 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.
2. The electronics control system of claim 1 , further comprising:
a thermal transfer structure connecting the at least one heat sink and the at least one thermal spacer.
3. The electronics control system of claim 2 , wherein the processor is a graphical processor.
4. The electronics control system of claim 1 , wherein the processor is not independently powered.
5. The electronics control system of claim 1 , wherein the auxiliary DC-DC converter powers the processor.
6. The electronics control system of claim 1 , wherein the cooling assembly is to simultaneously cool the power controller, the processor, and the auxiliary DC-DC converter.
7. The electronics control system of claim 1 , wherein the processor is a graphical processor.
8. The electronics control system of claim 1 , further comprising:
a housing that houses the cooling assembly, the power controller, the processor, and the auxiliary DC-DC converter.
