Abstract

The invention discloses a radiator which comprises a base and a plurality of radiating fins, wherein the radiating fins extend upwards from the base vertically. The base comprises a body part, the cross section of the body part is trapezoid, and an inclined air-guide face is disposed on each of two sides of the body part. The radiating fins comprise a plurality of parallel first radiating fins and second radiating fins at both sides of the first radiating fins, and each second radiating fin comprises a radiating part and two wind shields, wherein the radiating part extends from the base and is parallel to the first radiating fins, and the wind shields extend outwards from two ends of the radiating part in an inclining mode. Compared with the prior art, a flaring is formed by the two wind shields which are positioned at the same end of each second radiating fin, and thus air volume flowing through the radiating fins increases, heat is dissipated better, wind resistance is reduced effectively by the inclined air-guide faces of the body part when wind current passes by, and the wind current can pass through easily.

Description

Radiator

Technical field

The present invention relates to a kind of radiator.

Background technology

At present, usually utilize radiator to be attached to that the electronic component (as central processing unit) of the heating in the electronic installation such as server is upper to dispel the heat to electronic component.Along with the fast development of IT industry, the high speed of electronic component, high frequency and integrated its caloric value that makes increase severely, and need to more be beneficial to the dynamical radiator of heat radiation.

Summary of the invention

In view of above content, be necessary to provide a kind of radiator that more is beneficial to heat radiation.

A kind of radiator, comprise a base and some radiating fins that upwards vertically extends to form from base, base comprises a body, it is trapezoidal that the cross section of body generally is, a wind-guiding face that tilts is respectively established in the both sides of body, described radiating fin comprises some parallel the first radiating fins and lays respectively at the second radiating fin of the first radiating fin both sides, and each second radiating fin comprises that one extends from base and the radiating part parallel with the first radiating fin and is tilted to respectively two deep beads that extension forms from the two ends of radiating part.

Compare prior art, radiator of the present invention utilizes the common formation of two deep beads that are positioned at same end one enlarging of two second radiating fins, is used for increasing the air quantity of the radiating fin of flowing through, and is beneficial to heat radiation, the wind-guiding face of the inclination of body can effectively reduce windage distinguished and admirable through out-of-date, is beneficial to wind circulation.

Embodiment

Please refer to Fig. 1 to Fig. 3, radiator of the present invention comprises a base 10, some radiating fin 20 and some radiating tubes 30 that upwards vertically extends to form from base 10.

Four fixed parts 14 that base 10 comprises a body 12 and is divided into 12 4 jiaos of bodies.It is trapezoidal that the cross section of body 12 generally is, and a wind-guiding face 122 that tilts is respectively established in the both sides of body 12.Each fixed part 14 is offered a fixing hole 142 and is used for radiator is fixed in the mainboard (not shown).

Radiating fin 20 comprises some parallel the first radiating fins 22 and lays respectively at one second radiating fin 24 of these the first radiating fins 22 both sides.Each second radiating fin 24 comprises that one extends from body 12 and the radiating part 242 parallel with the first radiating fin 22 and two deep beads 244 that are tilted to respectively extension formation from the two ends of radiating part 242.

Each radiating tube 30 generally takes the shape of the letter U, and it comprises a base portion 31 that is fixed in body 12, the first heat-conducting part 32 that extends to form vertically upward from base portion 31 and the second heat-conducting part 33 that is parallel to body 12 that extends to form from the top of the first heat-conducting part 32.The second heat-conducting part 33 vertically is arranged in each the first radiating fin 22.

In present embodiment, two deep beads 244 common formation one enlargings that are positioned at same end of two second radiating fins 24 are for the air quantity that increases the radiating fin 20 of flowing through.The wind-guiding face 122 of the inclination of body 12 can effectively reduce windage distinguished and admirable through out-of-date, is beneficial to wind circulation.
