Description
Technical field
The utility model is related to radiator field more particularly to a kind of mainboard heat transmission passive heat radiation devices.
Background technology
Low side computer main board or liquid crystal television mainboard generally use passive heat radiation, traditional passive heat radiation device at present
Structure is generally contour radiating fin and is arranged on bottom plate, and entire radiating seat is bonded to dissipate to mainboard with mainboard by fastener
Heat, presently, there are the problem of be that mainboard the phenomenon that plate face warpage can occur during part SMD, to cause local connect
The problem of bad or even fastener is jumped out is touched, and common heat spreader structures are single, specific aim is not strong, and low side mainboard is deposited
The phenomenon that materials waste.
Utility model content
In view of the deficiencies of the prior art, the utility model, which provides one kind, prevents mainboard warpage, fitting from stablizing, material saving
Passive heat radiation structure.
Technical solutions of the utility model are as follows：A kind of passive heat radiation structure, including radiating seat and thermally conductive sheet, the heat dissipation
Seat includes radiating fin and bottom plate, it is characterised in that：The radiating fin is arranged in parallel in vertically on the bottom plate, adjacent institute
It states radiating fin to arrange in height, the bottom plate is relatively narrow to be extended with ear position on one side, and the ear position is equipped with mounting hole, described
Mounting hole is diagonally positioned, and the radiating seat and the thermally conductive sheet are thermally connected, and the thermally conductive sheet and mainboard chip are thermally connected, described
Radiating seat is fixed by screw and mainboard.
Specifically：The radiating fin and the bottom plate are aluminum extruded integrated molding.
Specifically：The height of the adjacent higher radiating fin is 2 times of relatively low radiating fin height, described adjacent scattered
The first air duct is formed between hot fin, and the second air duct is formed between the interval radiating fin.
Specifically：Hollow rivet is equipped in the mounting hole.
Specifically：Gasket is equipped with below the mounting hole, the screw passes through gasket that the radiating seat is made to fix, the pad
Piece is thicker 2mm than the thermally conductive sheet.
The beneficial effects of the utility model are：Radiating seat and mainboard are diagonally locked using screw, mainboard can be improved and stuck up
Bent phenomenon；Screw and hollow rivet cooperation locking, can prevent radiating seat from relative displacement occurs；The spaced and parallel row of radiating fin
Cloth and different in size save material while improving radiating efficiency.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the utility model embodiment exploded perspective view.
Fig. 2 is the utility model embodiment front view.
Fig. 3 is the utility model embodiment vertical view.
Wherein：1, hollow rivet 2, radiating seat 3, bottom plate 4, ear position 5, mounting hole 6, gasket 7, thermally conductive sheet 8, screw 9,
One air duct 10, the second air duct 11, radiating fin.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
- 3 a kind of passive heat radiation structure refering to fig. 1, including radiating seat 2 and thermally conductive sheet 7, the radiating seat 2 include heat dissipation
Fin 11 and bottom plate 3, it is characterised in that：The radiating fin 11 is arranged in parallel in vertically on the bottom plate 3, and adjacent is described scattered
Hot fin 11 is arranged in height, and the bottom plate 3 is relatively narrow to be extended with ear position 4 on one side, and the ear position 4 is equipped with mounting hole 5, institute
It is diagonally positioned to state mounting hole 5, the diagonal mounting hole 5 that is arranged not only locks firm but also saves material and space, the radiating seat 2
It is thermally connected with the thermally conductive sheet 7, the thermally conductive sheet 7 and mainboard chip are thermally connected, and the radiating seat 2 is solid by screw 8 and mainboard
It is fixed.
The radiating fin 11 and the bottom plate 3 are aluminum extruded integrated molding.
The height of the adjacent higher radiating fin 11 is 2 times of 11 height of relatively low radiating fin, the adjacent heat radiation
The first air duct is formed between fin 11, the second air duct is formed between the interval radiating fin 11, since radiating fin 11 is close
The partial heat of bottom plate 3 is higher, so there is independent heat dissipation wind channel between adjacent heat radiation fin 11, radiating fin 11 is far from bottom plate
3 portion temperature is relatively low, so just there is independent heat dissipation wind channel between the radiating fin 11 at interval, height parallel arrangement dissipates
Not only radiating efficiency improves but also saves material hot fin 11.
Hollow rivet 1 is equipped in the mounting hole 5, radiating seat 2 can be prevented by coordinating screw 8 to lock using hollow rivet 1
Relative displacement occurs.
5 lower section of the mounting hole is equipped with gasket 6, and the screw 8 passes through gasket 6 that the radiating seat 2 is made to fix, the gasket
6 than 7 thick 2mm of thermally conductive sheet, and during screw 8 locks mainboard and radiating seat 2, gasket 6 can make the bottom plate of mainboard and radiating seat 2
3 is parallel, to correct the warping phenomenon of mainboard.
Above-mentioned accompanying drawings and embodiments are merely to illustrate the utility model, and any technical field those of ordinary skill is to it
The appropriate changes or modifications done all should be regarded as not departing from the utility model patent scope.
