filled in the radiating cavity 33 in the initial state, when the cooling liquid overflows on the right side of the radiating cavity 33, the original cooling liquid in the radiating cavity 33 can flow out from the left radiating pipe 32 under the action of the extrusion force and finally flows into the closed space formed by the pressing plate 31 and the left partition plate 3, and the circulating flow of the cooling liquid in the radiating cavity 33 is realized in this way, in order to take away the heat of host computer 14 bottom, can realize carrying out the bottom heat dissipation to host computer 14 at the in-process that removes dust, when parts such as motor 22 output shaft reversal drive electrostatic board 291, rectangle long block 25, cleaning brush 266 move down, left and right sides electrostatic board 291 can insert respectively to left and right sides under 41 finally, in the in-process that electrostatic board 291 inserts under 41 under the under side electrostatic board 291 is the not electrified state, the board between under side 41 and the separating groove 42 can shovel the dust that electrostatic board 291 adsorbs, the dust that shovels down can get into in the box 43 of separating groove 42 in the inclined plane, with this realization to the collection of dust, and meanwhile, rectangle long block 25 can take cleaning brush 266 to slowly fall to 4 in, when cleaning brush 266 falls in collecting groove 4, the brush body can touch protruding strip 40, let the brush hair shake in this way, make the dust attached to cleaning brush 266 inside shake down, make things convenient for the operation of removing dust next time go on, finally, the part of cleaning dust can resume the normal position, accomplish a round of work and motor 22 stops the dust removal work and motor 22 shakes.

The foregoing is only a preferred embodiment of the present invention; the scope of the invention is not limited thereto.
