Description

A kind of circuit board cooling fin
Technical field
The utility model is related to circuit board component technical field, more particularly to a kind of circuit board cooling fin.
Background technology
Cooling fin is a kind of device to the easy heat-generating electronic elements heat dissipation in electric appliance, mostly by aluminium alloy, brass or bronze Make plate, sheet, splintery etc., if cpu central processing unit will use sizable cooling fin in computer, power supply in television set Pipe, row are managed, and the power tube in amplifirer will use cooling fin.General cooling fin in use will be in electronic component and cooling fin Contact surface applies last layer heat-conducting silicone grease, and the heat that component is sent out is made more effectively to be transmitted on cooling fin, then is dissipated through cooling fin It is dealt into surrounding air.
When radiating to circuit board, bad to the heat dissipation effect of circuit board, what is be unable to fully does existing cooling fin To the heat dissipation to circuit board, and when cooling fin is to be installed between circuit board, it is difficult to by between cooling fin and circuit board into Row separation, makes troubles to the repair of cooling fin, and cooling fin is easy to generate dust in inside when in use, gives the heat dissipation of cooling fin Effect is made troubles.For this purpose, it is proposed that a kind of circuit board cooling fin.
Utility model content
The main purpose of the utility model is to provide a kind of circuit board cooling fin, which improves heat dissipation The heat dissipation effect of piece plays the normal use that ensure that circuit board to the effect that circuit board well cools down, can band by shaft Dynamic hanging strip is moved, and hanging strip can clear up heat dissipation cavity both sides, avoid occurring dust inside heat dissipation cavity, ensure that cooling fin Internal is clean, can spring lever be plugged on inside grooves, convenient for will be fixed and dismantle between cooling fin and circuit board, just It is replaced and is repaired in heat dissipation plate, can effectively solve the problems in background technology.
To achieve the above object, the technical solution that the utility model is taken is:
A kind of circuit board cooling fin, including heat dissipation cavity, the heat dissipation cavity are internally provided with heat conductive rod, connect between the heat dissipation cavity Extension bar in succession, the connecting rod bottom connect shaft, and the heat dissipation cavity bottom connection erects cooling fin and erects cooling fin and heat conductive rod Connection, the heat conductive rod both sides connect horizontal cooling fin and horizontal cooling fin is located inside heat dissipation cavity, and heat dissipation cavity top both sides are set There are hook, described hook one end to be fixedly connected with spring lever, heat dissipation cavity surface side is equipped with groove.
Further, the hook and heat dissipation cavity are detachably connected by spring lever and groove.
Further, the shaft bottom connects hanging strip and hanging strip is arcuate structure.
Compared with prior art, the utility model has the advantages that:
1, a kind of circuit board cooling fin improves cooling fin using setting heat conductive rod, perpendicular cooling fin and horizontal cooling fin Heat dissipation effect plays the normal use that ensure that circuit board to the effect that circuit board well cools down.
2, by the way that shaft and hanging strip is arranged, hanging strip can be driven to be moved by shaft, hanging strip can be to heat dissipation cavity both sides It is cleared up, avoids occurring dust inside heat dissipation cavity, ensure that clean inside cooling fin.
3, due to setting hook, spring lever and groove, spring lever can be plugged on inside grooves, be convenient for cooling fin and electricity It is fixed and dismantles between the plate of road, convenient for heat dissipation plate is replaced and repaired, ensure that a kind of circuit board cooling fin makes With effect and utilization benefit, it is suitble to be widely popularized.
