Abstract

An electronic apparatus is provided with a housing containing a heat generating component, and a blower unit contained in the housing and used to cool the heat generating component. The blower unit includes an impeller, and a casing containing the impeller. The casing has suction ports, a chamber located around the impeller and a discharge port located at the downstream end of the chamber. The chamber has a depth gradually increased radially away from the impeller.

Description

technical field [0001] This application is based on and claims the benefit of priority from Japanese Patent Application No. 2002-020360 filed on January 29, 2002, the entire contents of which are incorporated herein by reference. [0002] The present invention relates to a centrifugal fan unit with a vortex chamber for converting velocity energy of air discharged by an impeller into pressure energy, and to an electronic device, such as a portable computer, equipped with the centrifugal fan unit. Background technique [0003] Portable electronic devices, such as portable computers, are equipped with microprocessors for processing various information. Due to increases in processing speed, and / or improvements in versatility, more and more heat is generated by microprocessors. Therefore, in order to keep the electronic device in a stable state, it is necessary to increase the heat dissipation from the microprocessor. [0004] The electronic device has a cooling unit for forced...
