Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies of the prior art and provide PCB circuit board, it has
It is simple in structure, it can aid in lowering the temperature of mainboard, small, cost is low, does not influence plug-in unit or the patch work of circuit board,
The advantages of shock-absorbing function can be played, improve service life.
Technical solution is used by the utility model：
PCB circuit board, it includes mainboard, and the side end face of the mainboard is equipped with positioning groove in a ring, and the positioning is recessed
Hot channel in a ring is installed, the hot channel is internally provided with transformer oil, the hot channel and mainboard inside groove
Between be fixedly connected by posting；The posting in a ring, is equipped with annular groove, the mainboard is determined on the inside of the posting
Position groove and annular groove cooperatively form the annular housing of installation hot channel.
The posting include arranged on the first annular body of mainboard upper surface, the second annular solid arranged on mainboard side end face and
The 3rd annular solid arranged on mainboard lower face.
The first annular body, the second annular solid and the 3rd annular solid are integrally formed, and the posting is by silica gel material
Manufactured posting.
The lower face array distribution of 3rd annular solid has some salient points.
Transformer oil inside the hot channel is with hot channel internal engagement formed with air cavity.
The mainboard is equipped with some screw installing holes penetrated through from upper end toward lower end.
The outer surface array distribution of the lateral wall of the hot channel has some radiating fins, and each radiating fin is homogeneous
End is arranged on the upper end of hot channel arranged on the lower end of hot channel and the other end, and gas is cooperatively formed between adjacent two radiating fins
Body circulation road.
The hot channel is the hot channel made of aluminium, and the surface of the hot channel lateral wall is coated with exhausted
Edge material layer.
Insulation material layer can be good at hot channel playing the role of next door, avoid the occurrence of short circuit phenomenon.Into one
Step, the arc-shaped contact portion of the inner side end of the cross section of the hot channel, the outside of the cross section of the hot channel
Face is in the radiator portion for facing shape directly.Hot channel can be good at radiating away while the temperature absorption by mainboard, particularly
It is provided with radiating fin and make it that heat dissipation effect is better.Posting enables to hot channel to be firmly fixedly mounted on master
The side wall of plate.Further, arc-shaped face inside the groove of the positioning groove of the mainboard side.Fixed by screw through screw hole
On the housing of equipment, the situation so if there is vibrations, then posting made of silica gel material can play slow
Punching acts on, while the salient point set causes damping effect better, while mainboard can be caused to change with the distance between housing,
The air between pump pressure mainboard and housing is thus formed, that is, the mobility of air can be increased, so can further be carried
High heat dissipation effect.Since what is filled inside hot channel is transformer oil, it can make it that heat dissipation effect is better, has inside hot channel
Air, can so increase the mobility of transformer oil, that is to say raising heat dissipation effect, simultaneously because transformer oil belongs to liquid
Body, that is to say that liquid can absorb the energy of vibrations during vibrations, can play the role of damping.
The utility model have it is simple in structure, can aid in lower mainboard temperature, small, cost is low, does not influence electricity
Plug-in unit or the patch work of road plate, the advantages of shock-absorbing function can be played, improve service life.
