Abstract

The utility model which relates to a heat dissipating device comprises a heat radiator, a wind guiding pipe and a fan, and the heat radiator comprises a heat conducting base plate, and one surface of the base plate is jointed with a central processor in order to absorb the produced heat; the top surface center of the base plate is fixedly connected with a round pipe which is provided with a plurality of round ventilation holes in order to increase heat dissipating effect; the external wall of the round pipe is jointed with a heat dissipating fin body which is a ring-shaped structure and is as high as the round pipe, and the fin body is provided with a plurality of fins which are arranged radially, and each fin is provided with a cut which is corresponding to the ventilation holes of the round pipe and is communicated to the external surface of the fins, of which is beneficial to air flows and wind resistance reduction, and the round pipe is connected with the wind guiding pipe, and the other end of the wind guiding pipe is connected with the fan; the fan can be fixed directly on the computer chassis, and the utility model can inhale the cold air out of the chassis and send the cold air to the surface of the heat radiator which is corresponding to the central processor through the wind guiding pipe, therefore, good heat dissipating effect can be reached.

Description

The heat abstractor combination

[technical field]

The utility model is about a kind of heat abstractor combination, refers to the heat abstractor combination that a kind of radiating effect is good especially.

[background technology]

Along with developing rapidly of computerized information industry, the arithmetic speed of computer cpu is more and more fast, and the heat that it produced is also more and more many, and too much heat is if can't in time discharge, the stability when having a strong impact on the central processing unit operation.For this reason, industry is installed the combination of a traditional aluminium extruded type radiator and fan usually in the central processing unit end face, and this fan is placed the radiating fin top of this radiator or is built in radiating fin central authorities, to assist to discharge heat.Common radiator combination is because the restriction of fan structure, cold air can't directly dispel the heat to the radiator surface corresponding with central processing unit, and heat is taken away can only treat that heat conducts to fin surface, the radiator outside time, and the rotation of fan also can cause the hot blast that overflows around the radiator to form backflow in computer housing, hinder replenishing of cold air, thereby influence radiating effect.And, because being the square formation shape mostly, arranges the radiating fin of traditional aluminium extruded type radiator, be unfavorable for air flows and easily produce big windage, and then influence radiating effect.

[summary of the invention]

The purpose of the utility model heat abstractor combination is to provide the good heat radiation dress of a kind of radiating effect to make up.

The purpose of the utility model heat abstractor combination realizes by following technical proposal: the utility model comprises a radiator, a guide duct and a fan.This radiator is made up of a heat-conducting substrate, a pipe and a fin, and wherein this pipe is the end face central authorities that are fixed in this substrate, offers some round vents on this pipe wall, to increase radiating effect; Also be fitted with a radiating fin on this circular tube external wall, this radiating fin is structure in the form of a ring, air vent hole at corresponding pipe is provided with the opening that connects to the fin outer surface, be beneficial to air flows and reduce windage, one end of this guide duct is connected with the pipe of radiator, and the other end then is connected with fan; And this fan can be directly fixed on the computer housing.Owing to adopted said structure, the combination of the utility model heat abstractor can suck the cold air of cabinet outside and rely on guide duct that cold air is delivered to the radiator surface corresponding with central processing unit, thereby reaches better radiating effect.

[embodiment]

See also Fig. 1 and Fig. 2, the combination of the utility model heat abstractor comprises that a radiator 10, a fan 30 and connect the plastics guide duct 20 of this radiator 10 and fan 30.

As shown in Figures 3 and 4, this radiator 10 comprises a heat-conducting substrate 40, a pipe 60 and a circular radiating fin 50.Wherein, these substrate 10 bottom surfaces can be attached on the central processing unit (figure does not show), its central authorities slightly are the arcuation evagination, to cooperate this radiating fin 50, its end face two ends then are respectively equipped with a microscler conduit 42, embed and firmly are installed in radiator 10 on the central processing unit for relevant fastener (figure do not show); This pipe 60 is fixed in this pedestal 40 end face central authorities, and it is a hollow column, offers some round vents 62 on the tube wall of this pipe 60, for circulation of air.This radiating fin 50 is bent continuously by sheet metal and forms, it has some fins 54 that are radial arrangement, the air vent hole 62 of these fin 54 corresponding pipes 60 is provided with the opening 52 of perforation to its outer surface, so that pipe 60 forms the gas channel that communicates with fin 54 outsides.This pipe 60 and circular radiating fin 50 are contour, and the two also can be fitted and be integral.

Other sees also Fig. 2 and Fig. 5, and these guide duct 20 1 terminations are located at pipe 60 tops of radiator 10, and its other end then forms a bigger air intake vent (figure does not show), and outwards protrudes out four grabs 22 in the periphery of this air intake vent, in order to fan attachment 30.

This fan 30 is the air intake vent place that buckle is connected in guide duct 20, and offers a perforation 32 respectively in the Qi Sijiao end, for some screw 34 correspondences it is locked on the computer housing.

Because the combination of the utility model heat abstractor relies on fan 30 that cool ambient air is sucked, and make cold air blow in the pipe 60 of radiator 10 via guide duct 20, join with hot-air, via air vent hole 62 and fin 54 surfaces heat is taken away again, to reach the effect of abundant heat radiation, and the air that can keep from heat forms backflow phenomenon and influences replenishing of cold air around radiator 10, thereby further promotes heat dissipation.
