Lose, it is ensured that radiating effect, in addition, the fluid space size that plugboard is plugged into cooling air channel that can be to being formed on substrate is adjusted
Section, to reach the purpose to cooling air quantity size adjustment.
Further, plugboard includes left plugboard and right plugboard, and the connected structure is to be separately positioned on substrate both sides
For the inserting groove that left plugboard and right plugboard grafting coordinate；It is easy for removal and installation, and seal is improved by grafting.
Further, cooling air channel is set in the way of cooling down wind and being flowed through from the middle of the cylinder head of both sides；Form good cooling effect
Really, in the present embodiment, it is Y-shaped structure to lead to machine two cylinder head, cooling air channel formed after be Y-shaped distribution；Realize simply, being easy to behaviour
Make, and be readily disassembled installation and safeguard, inserting groove mode outwards tilting after being inserted with the upper kuppe of correspondence is set；So that upper left
After kuppe and upper right kuppe grafting, the incline direction with logical machine cylinder head is consistent, and the distance between correspondence and fin keeps one
Cause, being easy to cooling, wind is smooth passes through, so as to improve thermal diffusivity.
Further, the fan cover body left and right sides is respectively arranged to correspondence plugboard limiting section front end and supports only form spacing
Limiting plate；Not only there is position-limiting action, in addition, limiting section front end is brought into close contact with the outer ledge of limiting plate, further formed
Preferable confined space, so as to improve the seal of duct space.
Further, substrate back root is that smooth arc-shaped transition forms flow-guiding structure to cooling down wind water conservancy diversion；Seamlessly transit
Structure passes through beneficial to airflow smooth.
Further, fan cover body rear end face periphery is provided with for being brought into close contact with logical machine wind-guiding shroud rim that to form insertion close
Close the cofferdam in air channel；By setting cofferdam structure, cofferdam circumferentially forms cladding overlap joint to the edge of fan housing component, not only with good
Good outward appearance, and can realize being brought into close contact by follow-up preload piece, bonding is not required to, it is convenient to dismantle and install.
Beneficial effects of the present invention：Logical machine fan guard of the invention, is used for by the substrate itself set on fan guard
The air channel of cooling cylinder head is formed, part can be not only saved, makes compact overall structure, and substantially increase the closed of cooling space
Type, reduces the windage loss in cooling space, and the windage loss in cooling space is reduced to greatest extent, it is ensured that radiating effect
Really；And this structure is realized simply, being easy to operation, and it is readily disassembled installation and safeguards, with easily transsexual.
