Description

The radiator of central processing unit

Technical field

The utility model relates to a kind of heat abstractor, relates in particular to a kind of radiator that improves the central processing unit of central processing unit radiating efficiency.

Background technology

As shown in Figure 1, 2, the existing radiator 20 that is used for central processing unit 10, mainly be one-body molded by a kind of Al squeezing material, comprise that one can attach the dull and stereotyped pedestal 21 that is contacted with central processing unit 10 upper surfaces, and several stand on the fin 22 on the dull and stereotyped pedestal 21, therefore, the radiator 20 of existing central processing unit 10 is that the heat conduction that central processing unit 10 produced by dull and stereotyped pedestal 21 is to fin 22, and increase the area of dissipation that contacts with air by several fin 22, to reach the effect of heat radiation.

Yet, because the radiator 20 of existing central processing unit 10 is with a kind of Al squeezing material moulding one, therefore it can provide the path of circulation of air, it is formed same as passage 23 only to be only limited to 22 of several fin, and these several fin 22 all become tabular, so it can provide the area of dissipation that contacts with air limited.So, 20 radiating efficiencys that can provide of radiator of existing central processing unit 10 are obviously limited, and especially, the information processing rate of central processing unit 10 is quick day by day at present, cause central processing unit 10 heating more easily, and the radiating efficiency of existing radiator 20 can not satisfy the demands obviously.

The utility model content

Exist the area of dissipation that contacts with air limited in order to overcome existing central processing unit radiator, radiating efficiency is not high, can not satisfy central processing unit information processing rate shortcoming fast day by day, the utility model provides a kind of radiator of central processing unit, it can increase area of dissipation greatly, have more circulations of air path, and then improve the radiating efficiency of central processing unit.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of radiator of central processing unit, comprise that one attaches the dull and stereotyped pedestal that is contacted with the central processing unit upper surface, and several stand on the fin on the dull and stereotyped pedestal, it is characterized in that described each fin all has several and generally is trapezoidal interval and first protuberance established, this first protuberance is convexly set in a side of fin side center line, and several generally are trapezoidal second protuberance of oppositely being located between two adjacent first protuberances, make second protuberance be positioned at the opposite side of fin side center line, first protuberance and second protuberance are interconnected to form and are wavy plate without exception, improve area of dissipation whereby; All has the 3rd protuberance that several protrude at interval on first protuberance and the sidewall that second protuberance is connected, make the 3rd protuberance be positioned at a side of first protuberance or the second protuberance center line, several oppositely are convexly set in the 4th protuberance between two adjacent the 3rd protuberances, make the 4th protuberance be positioned at the opposite side of first protuberance or the second protuberance center line, make the 3rd protuberance, the both sides of the 4th protuberance each with first protuberance, form a hole between second protuberance, more multidirectional circulation of air path can be provided whereby, and then can improve the radiating efficiency of radiator.

The beneficial effects of the utility model are that it can increase area of dissipation greatly, has more circulations of air path, and then improves the radiating efficiency of central processing unit.

Embodiment

As shown in Figure 3, the radiator 40 of the utility model central processing unit 30 comprises that one can attach the dull and stereotyped pedestal 41 that is contacted with central processing unit 30 upper surfaces, and several stand on fin 42 on the dull and stereotyped pedestal 41, it is characterized in that:

Please consult Fig. 4 simultaneously to shown in Figure 8, this each fin 42 all has several and generally is trapezoidal interval and first protuberance 421 established, and make first protuberance 421 be convexly set in a side (as shown in Figure 5) of fin 42 side centre line L 1, generally be trapezoidal second protuberance 422 of oppositely being located at 421 of two adjacent first protuberances with several, make second protuberance 422 be positioned at the opposite side of side centre line L 1, first protuberance 421 and second protuberance 422 are interconnected to form and are wavy plate without exception, can increase area of dissipation whereby; Simultaneously, on first protuberance 421 and sidewall that second protuberance 422 is connected, all has the 3rd protuberance 423 that several protrude at interval, make the 3rd protuberance 423 be positioned at a side (as shown in Figure 6) of first protuberance 421 or second protuberance, 422 centre line L 2, and several oppositely are convexly set in the 4th protuberance 424 of 423 of two adjacent the 3rd protuberances, and make the 4th protuberance 424 be positioned at the opposite side of first protuberance 421 or second protuberance, 422 centre line L 2, and make the 3rd protuberance 423, the both sides of the 4th protuberance 424 each with first protuberance 421,422 of second protuberances form a hole 425 (as shown in Figure 7), more multidirectional circulation of air path can be provided whereby, and then can improve the radiating efficiency of radiator 40.
