Abstract

The invention relates to a fan unit, comprising at least a frame and at least one fan wheel in the frame. The fan wheel comprises a hub and a blade set round the hub and extending outside. The frame comprises a channel and a penetrating hole. A first via hole and a second via hole are formed at two sides of frame by the channel. A first frame inclined and extending along radius direction is formed at the side of the first via hole by the frame and a second frame wall with opposite inclined direction to the first frame wall is formed at the side of the second via hole. The extending range outwards of the first frame wall exceeds the penetrating hole of frame at least and a third frame wall without declining is set between the first and second frame walls.

Description

technical field [0001] The invention relates to a fan unit, in particular to a fan capable of increasing the air intake. Background technique [0002] With the rapid advancement of industrial technology and semiconductor technology, the operating frequency of electronic components and chips continues to increase. For general computer hosts, the main heat source comes from the microprocessor, the north and south bridge chips on the motherboard, and the display card. High-performance chips, hard drives, optical drives, power supplies, etc. Among them, the heat source emitted by the microprocessor is the largest, and the higher the frequency of the microprocessor, the wattage of heat is even close to a hundred watts. High heat, and the high heat generated by it is equivalent to a hot metal plate. Such amazing heat may be even more serious in the days of rapid technological development in the future. However, personal computers and notebook computers currently on the market The...
