Problems solved by technology
As a result, the heat dissipation capacity of the fan is correspondingly weakened, which in turn causes the heat-generating electronic components in the electronic device to be unable to fully exert their performance due to limited heat dissipation.

Embodiment Construction
[0011] see figure 1 , an electronic device 100 according to a preferred embodiment of the present invention includes a casing 10 and a fan 20 placed in the casing 10 . In this embodiment, the electronic device 100 is a notebook computer, and the fan 20 is a centrifugal fan.
[0012] Please also see figure 2 , the fan 20 includes a fan frame 22 and an impeller 24 located in the fan frame 22 . The fan frame 22 includes a bottom plate 222 , a side wall 224 vertically extending upward along the outer edge of the bottom plate 222 , and a cover plate 226 connected to the side wall 224 . The cover plate 226 , the side wall 224 and the bottom plate 222 together form a chamber (not numbered) for accommodating the impeller 24 . The fan 20 is provided with a lateral air outlet 2240 , three axial first air inlets 2260 and an axial second air inlet 2220 . The air outlet 2240 is perpendicular to the first air inlet 2260 and the second air inlet 2220, that is to say, outside air enters ...

An electronic device comprises a main case and a fan which is arranged inside the main case. The fan comprises a fan frame and an impeller arranged in the fan frame, the fan frame comprises a bottom plate, a cover plate and a side wall which is located between the bottom plate and the cover plate, an air outlet is formed in the side wall, an air inlet which corresponds to the impeller is formed in the cover plate, the main case comprises a lower cover and an upper cover which is covered on the lower cover, the lower cover comprises a base plate and a side plate which extends upwards along the outer edge of the base plate, the cover plate of the fan is arranged closed to the base plate of the main case, an air outlet of the fan faces the side plate of the main case, the cover plate comprises a horizontal first area and a second area which inclines towards the inner side of the fan frame relative to the first area, the thickness of one side of the main case is larger than the thickness of the other side of the main case, and both the height of the base plate to the horizontal plane and the height of the second area to the horizontal plane become gradually larger from one side, with the thickness larger than the thickness of the other side, of the main case to the other side of the main case.
Description
technical field [0001] The invention relates to an electronic device, especially an electronic device with a fan. Background technique [0002] Nowadays, the design of electronic devices such as notebook computers and servers (such as various blade servers) is developing in the direction of high performance and thinness. In the limited housing space of electronic devices, more heating electronic components are stacked to Serving more and faster data processing functions. As a result, the design space reserved for the fan is decreasing, and the gap reserved between the fan and the case is getting smaller and smaller. In order to allow the fan to have a larger air output, the larger fan design is often caused by the slanted design of the casing. When the fan is working, only a small amount of external air can be drawn and used by the fan along the gap. As a result, the heat dissipation capability of the fan is correspondingly weakened, and the heat-generating electronic com...
