Description

Heat abstractor

[technical field]

The utility model is about a kind of heat abstractor, is meant a kind of heat abstractor with guide functions with increase integral heat sink effect especially.

[background technology]

Electronic components such as central processing unit all will produce a large amount of heat in normal running, if the heat of untimely its generation of eliminating will cause accumulation of heat to cause that temperature raises, and have a strong impact on the normal operation of electronic component.For this reason, industry is usually at these heat-generating electronic elements mounted on surface one heat abstractors, with auxiliary its heat radiation.

Known construction for heat radiating device, as No. the 520152nd, Taiwan patent announcement and No. 505375 disclosed content, generally include a radiator and a fan, this radiator comprises a pedestal and the some fin that are arranged on this pedestal, this pedestal and thermal source are sticked to absorb heat and to be transmitted to fin, this fan is installed on the above-mentioned fin, makes the air-flow that is blowed by fan that heat is further distributed from fin downwards.But, because heat-generating electronic elements such as central processing unit is little and be positioned at the center of this pedestal than the area of radiator base usually, cause this position, center temperature higher, and that fan radially relies on outside wind speed imperial palace crosswind speed is little, cause the slow even viscous flow of air current flow of radiator central region, thereby formation dead band, the heat that air-flow in this dead band carries difficulty distributes, further cause radiator center heat accumulation, become a high-temperature region, have a strong impact on the heat dispersion of heat abstractor, and may cause electronic components such as central processing unit to burn and cisco unity malfunction.

[summary of the invention]

Main purpose of the present utility model is to provide a kind of and has guide functions to increase the heat abstractor of integral heat sink effect.

The purpose of this utility model realizes by following technical proposal:

The utility model heat abstractor is used for distributing the heat that electronic component produces, this heat abstractor comprises a radiator and a fan, this radiator comprises a pedestal and at least one radiator that is arranged on this pedestal, the bottom surface of this pedestal contacts with electronic component to absorb heat, this radiator is made up of some fin, at least one fin is provided with towards the diversion division of the oblique extension in pedestal center, this fan is installed on this radiator, guide along the diversion division of radiator between pedestal center and this radiator outside by the air-flow that fan produces, thereby reach better radiating effect.

The utility model heat abstractor is owing to be provided with the diversion division that extends towards pedestal center direction on the fin of radiator, making can be along the concentrated pedestal center that acts on of these diversion divisions by the air-flow of fan generation, reach better radiating effect, effectively promote the integral heat sink performance of heat abstractor.

The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.

[embodiment]

Please refer to Fig. 1, the utility model heat abstractor is used for distributing the heats that electronic component produced such as central processing unit, comprise a radiator 10 and a fan 50, this radiator 10 comprises a heat conduction pedestal 30 and two radiators 20, and this fan 50 is fixed on two radiators 20 by two fixed frames 40.Wherein, this pedestal 30 comprises a pedestal 32 and along the upper surface of this pedestal 32 two parallel baffles 34 of one-body molded setting longitudinally upwards, this pedestal 32 is sticked to absorb heat with central processing unit (figure does not show), pedestal 32 is made by the good material of heat conductivility such as copper, aluminium etc. with baffle plate 34, each baffle plate 34 lateral surface combines the space that forms a carrying radiator 20 with the upper surface of this pedestal 32, form the ccontaining fastener groove 36 of (figure does not show) and insert and put between two baffle plates 34.

Please refer to Fig. 2 and Fig. 3, each radiator 20 is made up of the some fin 22 that are provided with that are arranged in parallel, each fin 22 is the sheet body structure of general square shape, be provided with first flanging 221 highly suitable with fin 22 lateral margins that radiator 10 baffle plates 34 are sticked mutually with baffle plate 34, fin 22 lateral margins that are sticked with radiator 10 pedestals 32 upper surfaces are provided with second flanging 222, the length of this second flanging 222 is corresponding with the radiator 10 pedestals 32 upper surface width that are positioned at baffle plate 34 outsides, above relative fin 22 lateral margins of first flanging 221, be provided with the 3rd flanging 223, these flangings 221 in addition, 222,223 all extend respectively in the same way along the direction vertical with fin 22; Run through offering a breach 224 on the 3rd flanging 223 and the fin 22, be provided with a diversion division 225 near these breach 224 positions; When each fin 22 is combined into radiator 20, respectively this first flanging 221 is in conjunction with forming a plane that is sticked with the lateral surface of baffle plate 34, respectively this second flanging 222 is in conjunction with forming a plane that is sticked with pedestal 32 upper surfaces that are positioned at baffle plate 34 outsides, to increase the contact area with the corresponding position that is sticked respectively, this first flanging 221, second flanging 222 and the 3rd flanging 223 also provide each fin 22 positioned at intervals effect simultaneously; This diversion division 225 is linearly a strip projection, its other side then forms the raceway groove that caves in, extend in the center direction that begins near breach 224 positions along near radiator 10 pedestals 32, this diversion division 225 can directly be made into integration by modes such as punching press, die casting and fin 22, the height of institute's projection can less than or be at least the spacing distance of adjacent fin 22, the area of institute's projection can be very big, makes the edge line of projection have guide functions; In addition, diversion division also can be the nick shaped that breaks through, can fill in a bar-shaped entity and be located in each fin in the breach that each diversion division forms, this diversion division self also can be provided with fastening structure, can reach by the fastening structure of adjacent diversion division to fasten and realize diversion function; Certainly, this diversion division 225 is not limited to linearly strip projection, also can be as curved strip projection or be the continuous dots structure of projection, this two radiator 20 also can be merged into a radiator and directly be sticked at pedestal 32 upper surfaces, and each radiator 20 also can be converted into the wavy structure with some fin 22 by a sheet metal Curved Continuous.

As shown in Figure 4, during assembling, some fin 22 are spliced to form radiator 20, thereby each radiator 20 is fixed on the upper surface of pedestal 32 with welding or mode such as gluing and combine formation radiator 10 with baffle plate 34 lateral surfaces, each fixed frame 40 is embedded in the fin 22 formed breach 224 of radiator 10 both sides, fan 50 is fixed on the fixed frame 40 to import cold air from the top, make fan 50 down during air-guiding, air-flow is just concentrated along the diversion division 225 of fin 22 and is directed to that heat is concentrated the most and fan 50 is not easy radiator 10 pedestals 32 centers that air-flow is directly imported, thereby reach the heat dispersion of effective lifting heat abstractor integral body, certainly, it is opposite with the type of action that imports cold air from radiator 20 tops that fan 50 also can be, promptly suck air-flow from radiator 10 pedestals 32 centers, and derive from radiator 20 tops, do not give unnecessary details at this.
