Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
First embodiment
Referring to fig. 1, the spiral scraping heat dissipation structure of the heat sink comprises a heat sink 1 and a rotating part 2 which rotates, wherein the rotating part 2 is formed by spirally distributing one or more scraping blades 3, the rotating peripheral surface and/or the rotating end surface of one or more scraping blades 3 are close to the surface of the heat sink 1, and the heat sink 1 is subjected to air-cooled spiral scraping heat dissipation when the rotating part 2 rotates.
One or more scraping pieces 3 are spirally distributed and arranged to form a rotating piece 2, meanwhile, the rotating peripheral surface and/or the rotating end surface of one or more scraping pieces 3 are close to the surface of the radiator 1, so that the contact area between the rotating piece 2 and the radiator 1 is increased, the rotating piece 2 can carry out air-cooled spiral suction and scraping heat dissipation on the radiator 1 through one or more scraping pieces 3 during rotation, hot air on the radiator 1 is quickly scraped away, the rotating piece 2 can drive new air flow to enter the radiator 1 while rotating, effective heat exchange is formed between the radiator 1 and the air, and quick cooling of the radiator 1 is realized.
The surface of the radiator 1 is provided with a main radiating surface 4, and the main radiating surface 4 points to the straight line and is in a concave arc groove shape; the rotating part 2 is partially positioned in the main radiating surface 4 in the shape of a circular arc groove. The outer end surfaces of the one or more scraping pieces 3 are arc-shaped and are spirally and uniformly distributed along the axis of the rotating piece 2.
Because the rotating part 2 is partially positioned in the main radiating surface 4 in the shape of the arc groove, the whole volume of the radiator 1 is reduced, and because the main radiating surface 4 is recessed on the surface of the radiator 1, the weight of the radiator can be further reduced, thereby reducing the production cost.
The arc shape of the outer end surface of one or more scraping blades 3 corresponds to the arc groove shape of the main radiating surface 4, and the two are close to each other.
Since the outer end surface shape of the wiper blade 3 corresponds to the shape of the primary heat dissipation surface 4, the contact volume between the two can be further increased. 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.
In order to improve the stability of the one or more scraping blades 3, the one or more scraping blades 3 are made of metal, plastic or flexible wear-resistant materials, the inner end surfaces of the one or more scraping blades are spirally and uniformly distributed along the axis of the rotating piece 2, and the outer end surfaces of the one or more scraping blades 3 are close to the main radiating surface 4.
When the heat radiator works, the rotating peripheral surface of the scraping blade 3 is always the highest position of the line speed in the whole rotating member 2 rotating at high speed under the high-speed rotation of the rotating member 2, so that the outer end surface of each scraping blade 3 in the rotating member 2 continuously, efficiently and circularly scrapes the heat conducted on the surface of the heat radiator 1 at high speed, and meanwhile, when the scraping blade 3 rotates away from the surface of the heat radiator 1, the heat is thrown out; when the scraping blade 3 continuously rotates to the surface of the radiator 1, the scraping blade 3 pushes cold air outside the radiator 1 to the surface of the radiator 1 and exchanges heat with the radiator 1, and in a cycle, the rotating piece 2 continuously rotates at a high speed to bring the external cold air to the surface of the radiator 1 for heat exchange and simultaneously scrape away heat exchanged with the cold air at a high speed, so that the ultra-efficient heat dissipation effect is realized, and the heat dissipation effect can be improved by dozens of times compared with the traditional mode that only the radiating fins are contacted with air. The direction of arrow a in fig. 1 is the flow direction of air.
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.
The radiator 1 is provided with a plurality of radiating fins 5 corresponding to the positions outside the main radiating surface 4, and the plurality of radiating fins 5 are respectively arranged on the radiator 1 in a manner that the top is open and the front and the back are through. The arrangement of the heat dissipation fins 7 can improve the heat dissipation effect of other positions of the heat sink 1.
The directions of the plurality of radiating fins 5 which are parallel to each other and are arranged in a penetrating manner are respectively parallel to or perpendicular to the axial direction of the rotating member 2. The heat radiating fins 5 of the present embodiment are arranged in a direction parallel to the axial direction of the rotary member 2.

The direction that circulation passage 6 of this embodiment set up is parallel to each other with the axis direction of rotating member 2 respectively, and water or other cooling fluid have been placed to its inside, through the flow of water or other cooling fluid, form the water-cooling effect, can take away a large amount of heats in radiator 1, and the air-cooled effect of cooperation rotating member 2 can improve the radiating efficiency of radiator 1 to the at utmost.
The direction of arrow B in fig. 2 is the flow direction of water or other cooling fluid, and it can be seen that the flow direction of water or other cooling fluid is parallel to the flow direction of air.
The other parts not described are the same as those of the first embodiment.
