Publication number: 20030012653Abstract: A cooling fan has a structure to prevent objects from being stuck by the blades of the cooling fan. The cooling fan includes rings spaced from the hub of the cooling fan, that prevent objects from striking the blades while the fan turns. As an alternative, a fan includes ribs radially spaced on the fan blades so as to deflect objects before being struck by the blades.Type: ApplicationFiled: July 13, 2001Publication date: January 16, 2003Inventor: Guy Diemunsch

Patent number: 6094345Abstract: In a modern computer, heat is removed from the internal power supply unit by means of a fan and ducting for channeling the airflow created by the fan through the circuitry of the power supply unit. The fan draws part of its air supply from the ambient air inside the computer casing and this helps to cool other components of the computer such as the microprocessor. As the power of microprocessors increases, the cooling requirement for this component has increased and heat sinks have been utilised to increase heat transfer to the surrounding air. Whilst further augmentation of heat removal could be achieved by increasing the power of the cooling fan, this would also increase noise levels. The present arrangement provides for increased heat removal without increasing fan power by arranging for the microprocessor heat sink to project into the ducting used to channel cooling air over the circuitry of the power supply unit.Type: GrantFiled: April 25, 1997Date of Patent: July 25, 2000Assignee: Hewlett-Packard CompanyInventor: Guy Diemunsch

Patent number: 6088223Abstract: Electronic apparatus comprises an electronic component which in use generates heat and a heatsink mounted within a housing having a thermal path to the electronic component. The heatsink comprises formations for generating by natural convection a cooling airflow for dissipating heat from the electronic component. Neighbouring first and second walls of the housing each comprise a vent structure and the formations of the heatsink define one or more oblique paths from the vent structure in the first wall across the heatsink to the vent structure in the second wall so that in at least a first operating orientation the cooling airflow generated by the heatsink passes from the vent structure in the first wall across the heatsink to the vent structure of the second wall and in at least a second operating orientation the cooling airflow generated by the heatsink passes from the vent structure in the second wall across the heatsink to the vent structure of the first wall.Type: GrantFiled: September 18, 1998Date of Patent: July 11, 2000Assignee: Hewlett-Packard CompanyInventor: Guy Diemunsch
