The rapid cooling device of the single crystal furnace, which is disclosed by the utility model, is simple in structure, convenient to use and good in cooling effect. According to the rapid cooling device, the cooling method is simple and easy to implement, forced cooling can be carried out in time on the main chamber of the single crystal furnace; compared with natural cooling, the rapid cooling device disclosed by the utility model has the advantages that 2-4h (or 30%-40%) of blowing out cooling time can be shortened, the equipment utilization rate and production efficiency of the single crystal furnace are improved, and the cost of crystal growth is reduced.
Description
Technical field
The utility model belongs to cooling tube technical field, relates to a kind of single crystal growing furnace quickly cooling device.
Background technology
Pulling of crystals is a kind of periodic, discrete production process.After each end cycle, all need to wait in stove temperature be cooled to 300 ℃ following after, just can tear the preparation work of stove, cleaning and next production cycle open.In addition, because pulling of crystals production process is lasting pyroprocess, in order to reduce crystal pulling energy consumption, be provided with a large amount of thermal insulation layers in stove, just cause needing to wait for that 6～10h can make thermal field in stove cool down after blowing out, this period accounts for 1/8 of the whole production cycle.During this, stove, in idle state, has reduced the operation factor of single-crystal manufacturing apparatus, has affected the efficiency of single crystal growing furnace crystal pulling.
The patent No. 200980109099.6, notification number CN101970728B, the patent of day for announcing 2013.01.30 proposes, from concubine takes out crystal bar, to utilize travel mechanism, and annular cooling conduit is declined towards crucible, carrys out cooling thermal field component.This method need to be implemented to force cooling from concubine takes out at crystal bar, therefore, force the cooling time that comes into effect to be restricted, and this apparatus structure is more complicated, easily causes stove internal contamination.

Fig. 2 is the quick cooling single crystal furnace device of the utility model and after blowing out, forces residing position view in process of cooling.
In figure, 1. cooling tube, 2. cooling medium inlet, 3. heat-eliminating medium outlet.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
Single crystal growing furnace quickly cooling device, comprises cooling tube 1 and drive unit thereof, and cooling tube 1 is provided with cooling medium inlet 2 and heat-eliminating medium outlet 3.A single crystal growing furnace can arrange one or more described quickly cooling devices.
Cooling tube 1 can adopt the metal tube of high thermoconductivity, as stainless steel or copper pipe etc., more excellent can use copper corrugated tube or spiral tube as cooling tube, reason is that copper has high thermal conductivity, the cooling main chamber's atmosphere contacting with cooling tube 1 promptly, thereby cooling thermal field component at short notice.
Quick cooling single crystal furnace device can rely on electric motor, the power wheel drive of hydraulic pressure or hand handle and realize up-and-down movement.
Can select as required the various refrigerants such as Oil, Water, Gas body or liquid nitrogen as heat-eliminating medium, and between furnace high-temperature thermal field component and environment, carry out heat exchange, the acceleration that realizes single crystal growing furnace is cooling.
Can, according to blowing out requirement cooling time, the combination of one or more above-mentioned quickly cooling devices be set in single crystal growing furnace bottom.
In single crystal growing furnace operational process, by cooling tube 1 drop to single crystal growing furnace outside, below thermal insulation layer; After single crystal growing furnace crystal pulling finishes, cooling tube 1, under the driving of drive unit, is increased to the high-temperature zone of single crystal growing furnace main chamber, and heat-eliminating medium is by carrying out heat exchange between cooling medium inlet 2 and heat-eliminating medium outlet 3 and furnace high-temperature thermal field component and environment; After cooling end, cooling tube 1 is subject to the driving of drive unit, drops to single crystal growing furnace outside, below thermal insulation layer.
In single crystal growing furnace operational process, this quick cooling single crystal furnace device drops to extreme lower position, outside in single crystal growing furnace, below thermal insulation layer, can not have influence on normal production, also can not increase extra energy consumption.After single crystal growing furnace crystal pulling finishes, this quick cooling single crystal furnace device is activated the driving of device and is increased to the high-temperature zone of single crystal growing furnace main chamber, by the heat exchange between heat-eliminating medium and furnace high-temperature thermal field component and environment, take away a large amount of heats, can effectively accelerate in stove cooling.After cooling end, quick cooling single crystal furnace device is activated the driving of device and drops to single crystal growing furnace outside.
Compare with naturally cooling, adopt the utility model single crystal growing furnace quickly cooling device can shorten 2-4h(or 30-40%) blowing out cooling time, improved plant factor and production efficiency, reduced single crystal growing cost.
