Abstract
A cooling system for an apparatus having heat generating components. The cooling system includes a housing and multiple sealed chambers. Fluid intake and exhaust ports are formed in the housing. The sealed chambers are for containing the heat generating components and are arranged within the housing to form a cooling fluid flow channel separating the sealed chambers from one another. The cooling fluid flow channel is in fluid communication with the fluid intake and exhaust ports.
Description
- Dust and other contaminants may adversely affect the operation of some computer components. Sealing the computer system can prevent contaminants from coming in contact with those components. However, sealing the computer system tends to increase the ambient air temperature inside the sealed chamber. Not all computer components can survive the high ambient air temperature inside a sealed chamber.
