Abstract
A cooling system of the invention can be used, for example, for cooling of electrical circuit boards housed in an equipment cabinet. The cooling system includes a flow-rate-amplifying pump configured to introduce ambient air into the cabinet. The pump is a passive device, which has a primary intake and a secondary intake and is designed to convert a small volume of compressed air applied to the secondary intake into a large flow of relatively cool ambient air into the cabinet through the primary intake. In one embodiment, the cooling system is designed to use the heat generated within the cabinet to produce compressed air. The air circulating around the circuit boards heats up and rises to the top of the cabinet, where it, is channeled toward an air vent. When the air exits through the vent, it rotates an appropriately placed propeller. The torque generated by the propeller is then used to drive an air compressor, the output of which is coupled to the secondary intake of the air amplifying pump. A cooling system of the invention can provide efficient cooling while generating less noise and/or electrical interference than prior art cooling systems.
