Description

Mixing device for heat radiation paste
[technical field]
The present invention relates to a kind of mixing arrangement, relate in particular to a kind of mixing device for heat radiation paste.
[background technology]
In recent years, along with the fast development of semiconductor devices integrated technique, the integrated degree of semiconductor devices is more and more higher, and it is more and more littler that device volume but becomes, and its heat radiation becomes a more and more important problem, and its requirement to heat radiation is also more and more higher.For satisfying these needs, various radiating modes are used in a large number, as utilize fan to dispel the heat, modes such as water-cooled auxiliary heat dissipation and heat pipe heat radiation, and obtain certain radiating effect, but because the contact interface and the out-of-flatness of radiator and semiconductor integrated device, generally be in contact with one another only less than 2% area, there is not desirable contact interface, fundamentally greatly influenced semiconductor devices and carried out the effect that heat is transmitted to radiator, therefore the exposure level that the higher thermal interfacial material of increase by one thermal conductivity factor increases the interface between the contact interface of radiator and semiconductor devices just seems very necessary.
Thermal grease also is widely used in the heat radiation of electronic component as a kind of important thermal interfacial material.Thermal grease is normally sneaked into high heat conduction particle in polymeric matrix material, for example aluminium (Al), silver (Ag), copper (Cu), boron nitride (BN), zinc oxide (ZnO), aluminium oxide (Al 2O 3) etc., make a kind of uniform liquid state or semisolid composite material.
See also Fig. 1, be the mixing device for heat radiation paste of prior art.This mixing arrangement 1 comprises a mixer 10 and an agitating device 100 that matches with described mixer 10.During use,, also be matrix material and heat conduction particle, place described mixer 10, stir described composite material 101, it is fully mixed by agitating device 100 rotations with material to be mixed 101.Yet when the tack of materials that mixes was higher, material just sticked on the rotor of agitating device easily, formed buildup, just can lose value after above-mentioned buildup sclerosis, caused waste of material.In addition, the agitating device of above-mentioned mixing arrangement is positioned at the central authorities of mixer, the material of edge can not fully mix, and the bottom of mixer easily produces the material sedimentation phenomenon, these all will cause material to be mixed to mix, operational difficulties will take place in mixing arrangement when serious, and mixing efficiency can't guarantee that also the performance of the thermal grease that is obtained will reduce greatly.
In view of this, provide a kind of and have the mixing device for heat radiation paste of higher mixture homogeneity and mixing efficiency in fact for necessary.
[summary of the invention]
Below, will a kind of mixing device for heat radiation paste be described with embodiment.
A kind of mixing device for heat radiation paste, it comprises: a horizontal mixer, described mixer has a cylinder shape inner wall; One agitating device, described agitating device comprises that a motor, a roller and connect the rotating shaft of described motor and roller, described roller places on the inwall of described mixer, the axis of described roller deviates from the axis of described mixer, and described rotating shaft drives the inwall rotation of described roller along mixer; And a container cover, be used to seal described mixer.
Compared with prior art, described mixing arrangement utilizes a rotating shaft to drive the inwall rotation of roller along an airtight mixer, roller is constantly oppressed material to be mixed with the gravity of himself and with the interaction force of mixer, and rotate formed shearing force with it with respect to mixer material to be mixed is fully mixed, can avoid mixing difficulty and mix uneven problem because of tack of materials to be mixed is higher.
