Information handling system riser card having adaptable height and airflow
An information handling system processes information with support from processing components disposed on a riser card coupled to a riser card cage and interfaced with the system processor. A guide coupled to the riser card cage slides relative to a riser card slot to adjust the riser card cage to accept riser cards of different dimensions. An airflow guide coupled to the guide adjusts based on the riser card dimension to direct cooling airflow in an efficient manner at the riser card processing components.
1 . An information handling system comprising: a housing; a motherboard coupled to the housing; a processor coupled to the motherboard and operable to execute instructions to process information; a memory coupled to the motherboard and operable to store the instructions and the information; a riser card slot interfaced with the motherboard and configured to couple with a riser card; and a riser card cage aligned with the riser card slot to couple a riser card in the riser card slot, the riser card cage having guide rails extending perpendicular from the riser card slot, a guide coupled to slide in the guide rails and an airflow guide coupled at a first end to the riser card cage and coupled at a second end to the guide, the guide sliding on the guide rails to change a shape of the airflow guide; and wherein the airflow guide has a slot at the second end; and the airflow guide couples to the guide with a pin through the airflow guide slot at plural locations, each of the plural locations adjusting the shape of the airflow guide.
2 . The information handling system of claim 1 further comprising:
a riser card coupled to the riser card slot in the riser card cage;
wherein the guide slides in the guide rails to press against the riser card.
3 . The information handling system of claim 2 wherein the airflow guide comprises an elastic material that bends to guide airflow towards the riser card.
4 . The information handling system of claim 1 , wherein the riser card and riser card slot interface with a PCI Express connection.
5 . The information handling system of claim 4 wherein the riser card comprises a graphics processing unit.
6 . The information handling system of claim 4 wherein the riser card comprises a network interface controller.
7 . The information handling system of claim 4 wherein the guide slides to a first position associated with a full height riser card and a second position associated with a low profile riser card.
8 . The information handling system of claim 4 further comprising a cooling fan aligned to blow cooling airflow across the riser card cage parallel to the riser card slot.
9 . A method for coupling a riser card in an information handling system, the method comprising: inserting the riser card into a riser card slot of a riser card cage; sliding a guide in guide rails of the riser card cage and against the riser card; and defining a cooling airflow channel in the riser card cage with an airflow guide coupled to the riser card cage and the guide; and further comprising coupling a pin through a slot of the airflow guide and to the guide; and sliding the airflow guide relative to the pin in the slot to adjust a curvature of the airflow guide.
10 . The method of claim 9 , further comprising: sliding the guide in the guide rails to a low profile position having a first airflow guide curvature; and sliding the guide in the guide rails to a full height profile having a second airflow guide curvature.
11 . The method of claim 10 wherein the riser card and riser card slot interface with a PCI Express connection.
12 . The method of claim 11 wherein the riser card comprises a graphics processing unit.
13 . The method of claim 11 wherein the riser card comprises a network interface controller.
14 . The method of claim 11 further blowing cooling airflow through the airflow channel with a cooling fan.
15 . A riser card system comprising: a riser card slot operable to interface with an information handling system motherboard and configured to couple with a riser card; and a riser card cage aligned with the riser card slot to couple a riser card in the riser card slot, the riser card cage having guide rails extending perpendicular from the riser card slot, a guide coupled to slide in the guide rails and an airflow guide coupled at a first end to the riser card cage and coupled at a second end to the guide, the guide sliding on the guide rails to change a shape of the airflow guide; and wherein the airflow guide has a slot at the second end; and the airflow guide couples to the guide with a pin through the airflow guide slot at plural locations, each of the plural locations adjusting the shape of the airflow guide.
16 . The riser card system of claim 15 further comprising:
a riser card coupled to the riser card slot in the riser card cage;
wherein the guide slides in the guide rails to press against the riser card.
17 . The riser card system of claim 15 , wherein the guide slides to a first position associated with a full height riser card and a second position associated with a low profile riser card.
