Abstract
A combination spray and cold plate thermal management system for effectively thermally managing a heat producing device during startup. The combination spray and cold plate thermal management system includes a spray unit thermally managing a heat producing device and a coolant reservoir thermally connected to the heat producing device. The coolant reservoir includes a porous media with coolant channels for storing a volume of the waste coolant after spraying of coolant has terminated. The coolant reservoir is fluidly connected to the spray chamber within the spray unit to receive the waste coolant.
Claims11
A thermal management system for thermally managing one or more heat producing devices, comprising:
- a heat producing device having a bottom surface and an upper surface;
- a spray unit attached to said heat producing device, wherein said spray unit includes a spray chamber and at least one spray nozzle;
- and
- a porous media connected to a bottom surface of said heat producing device;
- wherein said spray unit sprays atomized coolant upwardly upon said bottom surface of said heat producing device and said porous media to thermally manage said heat producing device;
- wherein said spray chamber within said spray unit receives a waste coolant produced from thermally managing said heat producing device;
- wherein said porous media retains waste coolant within said porous media when said spray unit sprays coolant;
- wherein at least a portion of said porous media extends downwardly and into a level of coolant within said spray chamber.
