Description
Technical field
The utility model relates to a kind of component devices of ingot furnace, is specifically related to a kind of novel ingot furnace refrigerating unit, belongs to production of polysilicon equipment technical field.
Background technology
Ingot furnace is the key equipment in polysilicon chip production process, and the silicon ingot weight of existing market main flow is between 500～800KG.According to state-of-art and crystalline silicon self physics-chem characteristic and polysilicon industrial development trend judge in the world at present, the production development trend of polycrystalline silicon ingot or purifying furnace is toward large specification (1000～1200KG), less energy-consumption (it is following that per kilogram silicon ingot consumes electric energy 7 degree), high-quality future development.So the research and development of G7 (even G8) silicon ingot are also brought into schedule.
But along with the continuous expansion of silicon ingot specification, the method by the crystallization of heat-insulation cage heat radiation, makes the heat of silicon ingot centre portions be difficult to shed, the long brilliant effect of impact, and also the long brilliant time also can be long
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of novel ingot furnace refrigerating unit, to overcome described defect of the prior art.
Utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of novel ingot furnace refrigerating unit, and it coordinates heat-insulation cage heat radiation, thereby optimizes long crystallographic system system, reduces energy consumption, produces high-quality silicon ingot.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of novel ingot furnace refrigerating unit, and it comprises lower furnace body, heat exchange platform, bottom heating device, drawing device, water-cooled copper dish, water-cooled cylindrical shell, water supply hose and delivery hose; Wherein, described heat exchange platform is supported on some graphite columns of lower furnace body; Described bottom heating device is positioned at the bottom of heat exchange platform; Described drawing device is positioned at bottom heating device below; Described water-cooled cylindrical shell is arranged on the bottom of lower furnace body, and extends into lower furnace body, is provided with water-cooled cylindrical shell water channel in it; Described water-cooled copper dish is placed in the top of water-cooled cylindrical shell, is provided with water-cooled copper dish water channel in it; Described water-cooled cylindrical shell water channel and water-cooled copper dish water channel are connected; Described water supply hose and delivery hose extend into water-cooled cylindrical shell, and are communicated with water-cooled copper dish water channel respectively.
Novel ingot furnace refrigerating unit of the present utility model is further set to: the cross section of described water-cooled copper dish is ladder structure, and it is the water-cooled copper dish of oxygen free copper material.
Novel ingot furnace refrigerating unit of the present utility model is further set to: between described water-cooled copper dish and water-cooled cylindrical shell, be respectively equipped with an O type circle between water-cooled cylindrical shell and lower furnace body.
Novel ingot furnace refrigerating unit of the present utility model is also set to: described water-cooled copper dish water channel is plough groove type water-cooled copper dish water channel.
Compared with prior art, the utlity model has following beneficial effect:
1, cost is low: the cross section of water-cooled copper dish is ladder structure, makes radial absorption heat, and in the situation that not affecting cooling performance, material cost reduces greatly; What adopt in addition is disk body inner channel, rather than the mode of copper pipe and the welding of copper dish, and the cost of material, artificial welding further reduces.
2, water supply hose and delivery hose directly join with water-cooled copper dish, so also just without this welding requirements.
3, security is higher: water-cooled copper dish is placed on water-cooled cylindrical shell; even if there is the situation of the whole overflows of silicon liquid, the water-cooled cylindrical shell of parcel asbestos layer not only can make water-cooled copper dish be placed on liquid level face, protection water-cooled copper dish; and can make liquid silicon rapid solidification, do not cause the accident of leaking.
4, welding effect is more reliable: what this water-cooled copper dish adopted is plough groove type water channel, and weld seam face is in furnace chamber outside, has avoided weld seam to be repeatedly in, in anaerobic high temperature and aerobic normal temperature state, weld seam likely occurs being oxidized the situation even coming off.
5, airtight effect is better: two places only adopt the sealing of O type circle, greatly reduce the possibility that causes gas leakage because sealing effectiveness is poor.
