Description
Technical field
The utility model relates to a kind of parts to semiconductor or other solid state device for ease of the cooling device of cooling to the selection of moulding, particularly a kind of electric solid state device heat abstractor.
Technical background
At present, development along with the electronic industry technology, the transistor density of all kinds of chips (particularly central processing unit) increases day by day, the speed of data processing is more and more faster, but the power that consumes and the heat of generation are also more and more higher, therefore, for guaranteeing the normal operation of each electric solid state device and equipment, need heat abstractor be set at thermal source, existing heat abstractor is generally a kind of radiating fin group, fins group by a base and base wherein the one side on a plurality of fins form, the bottom of fins group is covered on the thermal source, makes fins group draw the heat that heater element produced, and enlarges heat by fin and distributes the zone, heat is distributed, reach the purpose of heat radiation.But, for enlarging heat dissipation region, just need a fairly large number of fin, but be subjected to the restriction of electric solid state device volume, the volume of radiating fin group again can not be too big, therefore, gap between each fin is less, and it is still slower that heat distributes speed, thereby heat is detained on fins group, can't fast heat be distributed, influence the normal operation and the useful life of electric solid state device.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of can make the heat on the electric solid state device distribute more rapidly, the electric solid state device heat abstractor that makes electric solid state device can normal operation and prolong its useful life.
The utility model is realized by following approach.
Electricity solid state device heat abstractor comprises the heat radiation group, and its structural feature is: the heat radiation group has base and in some projectioies that the wherein one side of base forms, has the gap between adjacent two projectioies, and be distributed with plurality of holes on this heat radiation group.
Like this, the base of heat radiation group is attached on the thermal source, draws the heat that heater element produced by base, be passed on the projection then, enlarge area of dissipation by projection, simultaneously, the plurality of holes that on the heat radiation group, distributes, thereby further enlarge the area of dissipation on the heat radiation group, accelerate radiating rate, have rapid heat dissipation, the characteristics of good heat dissipation effect, can make the better normal operation of electric solid state device, and prolong the useful life of electric solid state device.
Structure of the present utility model can be specially:
Described hole or be a kind of perforation perhaps is a kind of blind hole.
Like this, when hole is a kind of blind hole, can enlarge the area of dissipation on the heat radiation group; When hole is a kind of perforation, both can enlarge the area of dissipation of heat radiation group, and, when this heat radiation assembly is closed fan and is used simultaneously, this perforation forms the passage of airflow again on the heat radiation group, when dispelling heat, can make the speed of airflow faster, further accelerate radiating rate by fan.
Described hole or be distributed on the base of heat radiation group perhaps is distributed on the projection of heat radiation group.
When hole is that this perforation is through to another side from the one side of base on a kind of base of the heat radiation group of boring a hole and be distributed in.
Like this, some perforation that on base, distribute, area of dissipation that not only can enlarged base, and also the hot-fluid that thermal source produces can be more conducive to distributing of heater element heat by the circulation of the perforation on the base.
When hole is on a kind of projection of the heat radiation group of boring a hole and be distributed in, and runs through each projection of heat radiation group with a kind of direction parallel with base.
Like this, on each projection of heat radiation group, all have perforation, and, this perforation to run through direction parallel with base, when all having perforation on the base of heat radiation group and the projection, therefore have crisscross heat dissipation channel on the heat radiation group, thereby help distributing of heat more.
The heat radiation group is by carborundum, alundum (Al, the injection molding a kind of heat-sink unit of a kind of ceramic material that silicon dioxide and binding agent mix.
Like this, because carborundum has high thermal conductivity, be that main raw material(s) is processed into the heat radiation group with carborundum, therefore, this heat radiation group has the characteristic of good heat dissipation effect.
Structure of the present utility model can further be specially:
Each is protruding or be a kind of vertical bar shape that is parallel to each other, and perhaps is a kind of bending.
In sum, the utility model has following advantage compared to prior art: the heat radiation group is made up of the projection on base and the base, and on the heat radiation group, plurality of holes is set, thereby enlarge the area of dissipation of heat radiation group, increase radiating effect, help the normal operation of electric solid state device and prolong its useful life.
