Description

A kind of air-cooled radiator
Technical field
The utility model belongs to heat sink technology field, and in particular to a kind of air-cooled radiator.
Background technique
Air-cooled radiator operating mode are as follows: the heat that power module generates when working installs contact surface by it with thermally conductive Mode pass to substrate, then heat is diffused to from substrate by cooling fin in thermally conductive mode, finally in a manner of heat convection Heat is transferred in atmospheric environment from air-cooled radiator.And after whole system reaches thermal balance, substrate temperature can maintain The temperature range that power module can work normally.
The cooling fin material high usually using thermal conductivities such as copper, aluminium, and intensive sheet type is processed into increase and heat The contact area of wind, to improve radiating efficiency.But the cooling fin of sheet type is easy to be generated trembling by distinguished and admirable pressure, Cause heat dissipation performance unstable, can also generate vibrating noise, it is therefore desirable to add reinforcement structure in the upper end of cooling fin with fixation Cooling fin.A kind of existing fixed structure usually substrate of the end design with card slot, such as patent " wind-cooling heat dissipating on a heat sink Device " (application No. is CN201720555140.4), disclose a kind of air-cooled radiator comprising side plate, substrate, at least one Between plate and cooling fin, side plate connects to form accommodating space with substrate, and intermediate plate is set on accommodating space, the side of intermediate plate and dissipates Backing connection.Need repeatedly overturning substrate the upper and lower side of cooling fin could be respectively arranged in base when the assembling radiator of the structure On plate, assembling is laborious, low efficiency, and upper substrate is full slice system structure, heavy, mobile inconvenient, cooling fin be not easy with it is upper Card slot alignment in substrate.
Utility model content
The purpose of the utility model is to provide a kind of air-cooled radiator, the heat dissipation effect of the air-cooled radiator is stablized, heat dissipation Piece is not easy to tremble, and operating noise is small, easy to assembly laborsaving, and packaging efficiency is high.
The utility model provides the following technical solution:
A kind of air-cooled radiator, including substrate, the left and right sides above substrate are fixed with a baffle, two gears respectively It is equipped with several parallel cooling fins between plate, gap is equipped between cooling fin, is respectively equipped with the first peace on the upside of two baffles Hole is filled, the first mounting hole is round hole, and the top of cooling fin is equipped with the second mounting hole, and the second mounting hole is semi-circular hole;This reality With it is novel further include horizontally disposed fixed link, fixed link is arranged along the direction perpendicular to fin array, and fixed link is arranged in It in first mounting hole, and is placed on the second mounting hole, fixed link is cylinder type, and edge is axially arranged with several in fixed link The limited block to match with the position in the gap of cooling fin, the width of limited block are slightly less than the width in gap, and rotation fixed link can It is placed in limited block in gap and resists cooling fin.Fixed link is installed on the upside of baffle and cooling fin, can reinforce cooling fin it Between bonding strength, preventing the upside of cooling fin from being trembleed by distinguished and admirable pressure causes heat dissipation effect unstable and generates The phenomenon that biggish vibrating noise.Fixed link can rotate in the first mounting hole and the second mounting hole, and the second mounting hole is Semi-enclosed semi-circular hole, therefore, when installation can first by the limited block of fixed link upward, i.e., limited block is not placed in the second peace It fills in hole, so that limited block be made not limited by the position of the second mounting hole, can quickly place fixed link;Limited block is adjusted again Position makes it be directed at the gap between cooling fin, and rotating fixing rod, is stuck in limited block in gap, and installation positioning is quick It is laborsaving, it does not need to overturn substrate and cooling fin back and forth, only rotating fixing rod.
Preferably, limited block is sector structure, and limited block is welded in fixed link, the limited block and cooling fin of sector structure Between have biggish contact area, conducive to cooling fin is stablized.
Preferably, the both ends of fixed link are equipped with the first screw thread;The utility model further includes multiple matched with the first screw thread Nut, nut are threadedly coupled with the both ends of fixed link.Nut fastens the connection between fixed link and baffle and cooling fin more, It is not easy to loosen due to by distinguished and admirable vibration influence.
Preferably, the quantity of fixed link is two, and two fixed links are symmetrically distributed in the top of cooling fin.
Preferably, corrugated fin is additionally provided between cooling fin, corrugated fin includes the dog-ear of ripple type, the side wall of cooling fin Several V-grooves are equipped with, dog-ear is connected in V-groove.Corrugated fin can using thermal conductivity be higher than air thermal conductivity copper, The metal materials such as aluminium are made, and because the hot wind in this gap is contacted with corrugated fin, more heat can be taken away when blowing air over cooling fin Amount, improves radiating efficiency.The dog-ear of corrugated fin is connected in V-groove, when the corrugated fin pressure distinguished and admirable by high speed not It is easy vertical tremor, is also not easy to generate friction between cooling fin, therefore further reduces and is produced because of corrugated fin vibration Raw frictional heat and noise.
The beneficial effects of the utility model are: fixed link and limited block are fixed on the upside of cooling fin, enable cooling fin It reliably works, is not affected by the wind generation shaking, heat dissipation effect is stablized, while reducing the trembling noise of cooling fin;Pass through Limited block can be quickly and easily fixed in the gap between cooling fin by the first mounting hole and the second mounting hole, not need to turn over Transglutaminase substrate and cooling fin, it is time saving and energy saving to install;Corrugated fin between cooling fin improves radiating efficiency, and corrugated fin is connected in In the V-groove of cooling fin, reduce frictional heat and vibrating noise.
