The invention discloses a radiator fixing device and a radiator. The radiator fixing device comprises a spring, a fixing screw and a fixing hole; the fixing hole is arranged on a circuit board; and the spring passes through the fixing screw and is connected with the fixing hole on the circuit board. The radiator fixing device and the radiator provided by the invention are reasonable in structure and reliable to fix and have the buffer effect, such that a chip on the circuit board is effectively protected; the heat dissipation effect of the radiator fixed by the fixing device is good; and the working performance of the chip is effectively ensured.
Description
Technical field
The present invention relates to a kind of fixture, particularly relate to a kind of fixer for heat radiator and radiator.
Background technology
General electronic component produces large calorimetric when running, and itself and system temperature are raised, and too high temperature can cause the decline of its runnability.For this reason, industry is installation of heat radiator on electronic component usually, discharges the amount of heat that it produces.
In the local side communications field, the mainboard chip on the terminal equipment of connecting fiber main line, chip volume is large, and communicating requirement is high, and transmission rate is fast, and chip power-consumption is large, and the heat of generation is many.
Use conventional radiator fixed form: between electronic component and radiator contact-making surface, smear one deck heat-conducting silicone grease, use heat-conducting silicone grease to be pasted fixing.Chip volume is comparatively large, therefore, needs the radiator of corresponding size; The radiator using heat-conducting silicone grease fixing is easily under self gravitation effect, and situation about dropping, affects the service behaviour of chip to a certain extent, may affect the normal operation of the terminal equipment of fiber optic backbone.
Summary of the invention
The object of the invention is for above-mentioned technical problem, provide a kind of fixer for heat radiator and radiator, it is rational in infrastructure, fixing reliable, and has cushioning effect, the chip on available protecting circuit board; The radiator heat-dissipation using this fixture fixing is effective, effectively ensure that the service behaviour of chip.
Technical scheme of the present invention:
For solving the problems of the technologies described above, the invention provides a kind of fixer for heat radiator, it comprises spring, fixed screw and fixing hole; Fixing hole is arranged on circuit boards, and spring is connected with the fixing hole on circuit board through fixed screw.
Further, described fixing hole arranges the edge of chip fixed position on circuit boards.
Further, described fixing hole magnitude setting is four.
Further, described spring inside diameter size and the outside dimension of fixed screw are equipped with.
A kind of radiator, it comprises base, fin, fin and base one-body molded; Above-mentioned fixer for heat radiator processing heat radiator and circuit board is used to fix.
Further, described base is provided with location hole, the position one_to_one corresponding of the fixing hole on the position of location hole and circuit board.
Further, the fin of described location hole corresponding position is provided with breach, to facilitate the installation and removal of fixed screw.
Further, described breach is square.
Beneficial effect of the present invention:
Fixer for heat radiator provided by the invention and radiator, it is rational in infrastructure, fixing reliable, and has cushioning effect, the chip on available protecting circuit board; The radiator heat-dissipation using this fixture fixing is effective, effectively ensure that the service behaviour of chip.
Accompanying drawing explanation

Use the concrete steps of heat-sink fixing device fixed heat sink of the present invention as follows:
First, circuit board 5 is determined the fixing hole of chip 4 correspondence;
Then, according to the position of fixing hole, the correspondence position machining gap 7 of fin 6 on a heat sink;
Then, locating and machining hole on the base 1 of radiator breach 7 correspondence;
Finally, mounting spring 2 on fixed screw 3, fixes radiator on the circuit card 1.
Fixer for heat radiator provided by the invention and radiator, it is rational in infrastructure, fixing reliable, and has cushioning effect, the chip on available protecting circuit board; The radiator heat-dissipation using this fixture fixing is effective, effectively ensure that the service behaviour of chip.
The present invention is illustrated by above-mentioned execution mode, but should be understood that, above-mentioned execution mode just for the object of illustrating and illustrate, and is not intended to the present invention to be limited within the scope of described execution mode.It will be appreciated by persons skilled in the art that and can also make more kinds of variants and modifications according to instruction of the present invention, within these variants and modifications all drop on the present invention's scope required for protection.
