Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
First embodiment
Referring to fig. 1, the improved heat sink scraping heat dissipation structure includes a heat sink 1 and a rotating member 2 that rotates, wherein the rotating member 2 is formed by annularly distributing a plurality of scraping blades 3; a circular groove (not marked in the figure) is formed in the surface of the radiator 1, and a main radiating surface 4 is arranged on the surface of the circular groove; the rotating piece 2 is positioned in the circular groove; the rotary peripheral surfaces and/or rotary end surfaces of the plurality of scraping blades 3 are close to the surface of the main radiating surface 4.
Set up a plurality of doctor-bar 3 annular distribution and constitute rotating member 2, and set up rotating member 2 in recessed circular recess on radiator 1 surface, the rotatory outer peripheral face and/or the rotatory terminal surface of a plurality of doctor-bar 3 are close to each other with the main radiating surface 4 of circular recess, thereby improve the area of contact of rotating member 2 and radiator 1, rotating member 2 can carry out the vertical heat dissipation of scraping of air-cooled formula to radiator 1 through a plurality of doctor-bar 3 when rotatory, thereby scrape away the hot-air on radiator 1 fast, avoid the two problem that leads to the hot-air to scrape away because of the existence in clearance, and rotating member 2 still can drive new air current entering radiator 1 when the pivoted, form heat exchange effectively between messenger's radiator 1 and the air, in order to realize radiator 1's rapid cooling.
In order to improve the use stability of the scraping blades 3, the scraping blades 3 are made of metal, plastic or flexible wear-resistant materials and are uniformly distributed in a circular ring shape, and the rotary outer peripheral surface and/or the lower edge and/or the middle part and/or the upper edge of the rotary end surface are close to the surface of the main radiating surface 4.
Theoretically, if the wear between the parts is neglected, the contact between the blade 3 and the surface of the heat sink 1 is best, and the occurrence of air leakage due to the existence of a gap can be avoided, so as to improve the heat dissipation density.
The rotating member 2 is in a water wheel shape, and the inner ends of the plurality of scraping sheets 3 are intersected at the axle center of the rotating member 2.
The circular grooves are straight and directed and are longitudinally recessed on the surface of the radiator 1; the rotating piece 2 is arranged in the circular groove and is arranged on the same axis with the circular groove; the rotating part 2 carries out air-cooled drawing and scraping heat dissipation on the inner wall and the bottom of the circular groove of the radiator 1 through the plurality of scraping blades 3 during rotation.
Because the rotating piece 2 is arranged in the circular groove, the whole volume of the radiator 1 is reduced, and the circular groove is longitudinally recessed on the surface of the radiator 1, so that the weight of the radiator 1 can be further reduced, and the production cost is reduced.
Meanwhile, as the rotating piece 2 is arranged in the circular groove, the rotating peripheral surfaces of the plurality of scraping pieces 3 and/or the lower edges, the middle parts and the upper edges of the rotating end surfaces are close to the surface of the main radiating surface 4, so that the contact area between the rotating piece 2 and the radiator 1 can be further increased, and more hot air can be sucked and scraped.
The heat sink 1 is provided with a bearing (not shown) and a driving motor (not shown) corresponding to the rotation of the rotating member 2, and the rotating member 2 rotates on the heat sink 1 through the cooperation of the bearing and the driving motor.

When the heat radiator works, the rotating part 2 rotates at a high speed, the rotating peripheral surface and/or the rotating end surface of each scraping blade 3 is always close to the main heat radiating surface 4, therefore, the rotating peripheral surface and/or the rotating end surface of each scraping blade 3 in the rotating part 2 can continuously, high-efficiently and circularly suck heat conducted by the surface of the heat radiator 1 from one longitudinal side at a high speed, and simultaneously push cold air outside the heat radiator 1 into the circular groove from the other longitudinal side and exchange heat with the heat radiator 1, and in a cycle, the continuous high-speed rotation of the rotating part 2 brings the cold air outside to the surface of the heat radiator 1 for heat exchange and simultaneously scrape the heat exchanged with the cold air at a high speed, so that the ultra-efficient heat radiating effect is realized, and the heat radiating effect can be improved by dozens of times compared with the traditional mode that only depends on the contact of radiating fins and air.
Because the middle parts of the radiating fins 5 are communicated with the circular grooves, heat conducted on the surface of the radiator 1 can be scraped away from one side of the radiating fins 5 under the high-speed rotation of the rotating piece 2, and meanwhile, external cold air can be pushed into the circular grooves from the other side of the radiating fins 5, so that the air-cooled longitudinal and transverse scraping heat dissipation of the radiator 1 is realized, and the heat dissipation efficiency of the radiator 1 is further improved.
