Abstract
A centrifugal fan frame body structure includes a lower case body and a cover body. The lower case body has a bottom section and an outer wall section. The outer wall section is formed with a wind outlet. The cover body and the lower case body are correspondingly mated with each other to form a space. In the space, the lower case body and the cover body define therebetween a first height. The lower case body and the cover body define therebetween a second height at the wind outlet. The second height is larger than the first height. The height of the wind outlet is enlarged, whereby the wind outlet will not be blocked by the cooperative heat dissipation component (module) so that the flow field efficiency is enhanced and the noise is lowered.
Claims7
A centrifugal fan frame body structure comprising:
- a lower case body having a bottom section and an outer wall section, the outer wall section being vertically annularly disposed along a periphery of the bottom section, the outer wall section being formed with a wind outlet;
- and
- a cover body having an upper side, a lower side and a wind inlet, the wind inlet passing through the cover body between the upper and lower sides, the cover body and the lower case body being correspondingly mated with each other to form a space, the wind outlet being in communication with the wind inlet via the space, in the space, the lower case body and the cover body defining therebetween a first height, the lower case body and the cover body defining therebetween a second height at the wind outlet, the second height being larger than the first height;
- and
- a thermal module being disposed at the wind outlet and having a height lower than the second height at the wind outlet.
