Abstract
The utility model relates to a semiconductor refrigeration production technical field's equipment, the name is pulling furnace with electric field deflects, including the furnace body, the furnace body has the furnace chamber, has the cassette of installation crystal pulling pipe in the furnace chamber, the furnace chamber in crystal pulling cover in addition, the crystal pulling cover is the part that carries out the crystal pulling to the product, the inside both sides of furnace chamber be provided with two plate electrodes, galvanic positive and negative polarities are connected respectively to the plate electrode, galvanic voltage and the ratio between two polar plates be 80 - 90v / decimetre, DC power supply's switch and crystal pulling cover connection control device, such pulling furnace with electric field deflects has the advantage that the crystal pulling is effectual, production efficiency is high.
Description
Technical field
The utility model relates to the equipment of semiconductor refrigeration member production technical field, particularly relates to crystal pulling furnace.
Background technology
Crystal grain is the parts manufacturing semiconductor refrigeration member, and the main component of crystal grain is three telluride two bismuths, and require that its molecular arrangement is neat as the crystal grain manufacturing cooling component, the molecular arrangement inside crystal grain is more neat, and the efficiency of cooling component is higher.
Crystal grain is formed by crystal bar cutting, and this just requires that the molecular arrangement inside crystal bar is neat.
When manufacturing crystal bar, the process arranged the molecule inside it is exactly crystal pulling, crystal pulling is carried out in crystal pulling furnace, raw material is contained in crystal pulling tube and carries out crystal pulling, in prior art, do not arrange deflecting electric field in crystal pulling furnace, namely crystal pulling carries out when zero deflection electric field, has crystal pulling weak effect, the crystal pulling time is long, production efficiency is low shortcoming.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, provides the crystal pulling furnace that a kind of crystal pulling is effective, production efficiency is high---there is the crystal pulling furnace of deflecting electric field.
The technical solution of the utility model is achieved in that the crystal pulling furnace with deflecting electric field, comprise body of heater, body of heater has furnace chamber, there is the deck installing crystal pulling tube in furnace chamber, crystal pulling cover is also had in described furnace chamber, crystal pulling cover is parts product being carried out to crystal pulling, it is characterized in that: the inner both sides of described furnace chamber are provided with two battery lead plates, and battery lead plate connects galvanic positive and negative polarities respectively.
Preferably, the ratio between described galvanic voltage and two pole plates is 80-90v ∕ decimetre.
Say further, the switch of described direct supply and crystal pulling cover connection control device.
The beneficial effects of the utility model are:
1, such crystal pulling furnace with deflecting electric field has the advantage that crystal pulling is effective, production efficiency is high;
2, the ratio between described galvanic voltage and two pole plates is 80-90v ∕ decimetre, has the advantage of better effects if;
The switch of 3, described direct supply and crystal pulling cover connection control device, have the advantage that level of automation is high.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model.
Wherein: 1, body of heater 2, furnace chamber 3, deck 4, crystal pulling cover 5, battery lead plate 6, crystal pulling tube 7, control device.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, there is the crystal pulling furnace of deflecting electric field, comprise body of heater 1, body of heater has furnace chamber 2, in furnace chamber, have the deck 3 installing crystal pulling tube, also have crystal pulling cover 4 in described furnace chamber, crystal pulling cover is parts product being carried out to crystal pulling, it is characterized in that: the inner both sides of described furnace chamber are provided with two battery lead plates 5, and battery lead plate connects galvanic positive and negative polarities respectively.In the process of such crystal pulling, crystal pulling tube 6 will be in deflecting electric field, is conducive to the arrangement of molecule inside it, has advantage of the present utility model.
Preferably, the ratio between described galvanic voltage and two pole plates is 80-90v ∕ decimetre.Distance such as between two pole plates is 20 centimetres, and the voltage between required pole plate is 160-180v, can obtain good crystal pulling effect like this.
Say further, the switch of described direct supply and crystal pulling cover connection control device 7.
The foregoing is only specific embodiment of the utility model, but constitutional features of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed in the scope of the claims of the present utility model.
Claims (3)
