Abstract
The utility model relates to a heat conducting graphite block. By arranging a heat-dissipation groove in the middle of the square heat conducting graphite block, the heat conducting graphite block can uniformly conduct heat, thus reducing the transverse temperature gradient, and therefore a crystal surface can approximate to a plane, meeting the ideal requirement of the solidification technology for multicrystalline silicon. The heat conducting graphite block is widely applicable to solar multicrystalline silicon ingot production systems and directional solidification systems for metal alloys.
Description
One, technical field
The utility model relates to a kind of graphite heat conducting piece.Particularly be used in polysilicon directional freezing graphite heat conducting piece.
Two, background technology
In solar energy polycrystalline silicon ingot casting system, the graphite heat conducting piece is vital part, plays heat conducting effect in the process of melting polycrystalline silicon material and the polycrystalline silicon material process of setting, and its structural performance directly has influence on the quality of polycrystalline silicon ingot casting; Graphite heat conducting piece of the prior art is a cube structure, in the material solidification process, because the influence of stay-warm case and well heater on every side, heat dissipation capacity is little greatly all around for heat dissipation capacity in the middle of the graphite heat conducting piece, and the transverse temperature gradient is increased, and influences the consistence that polycrystalline silicon material solidifies;
Three, summary of the invention
At the problem that above-mentioned prior art exists, it is a kind of simple in structure, easy to manufacture that goal of the invention of the present utility model is to provide, and meets the solidifying process requirement, outstanding effect graphite heat conducting piece.
Graphite heat conducting piece of the present utility model comprises graphite heat conducting piece 1 and its intermediary groove 2; The shape of groove 2 can be a square column type, also can be trapezoidal, and groove floor can be a flush type, also can be the arc concave shape.
Innovation part of the present utility model is to make the uniform heat conduction of graphite heat conducting piece by at graphite heat conducting piece intermediary groove 2, thereby optimizes the effect of graphite heat conducting piece;
Four, description of drawings
Fig. 1 is a structural representation of the present utility model;
Referring to shown in Figure 1, comprise graphite heat conducting piece 1 and its intermediary groove 2; The shape of groove 2 can be a square column type, also can be trapezoidal, and groove floor can be a flush type, also can be the arc concave shape.
Accompanying drawing 2 is a specific embodiment of the utility model;
Referring to shown in Figure 2, it is the synoptic diagram of a polycrystalline silicon ingot casting system, the utility model graphite heat conducting piece 1, groove 2 are placed on the pillar stiffener 3, polycrystalline silicon raw material and crucible parts 9 are placed on the graphite heat conducting piece 1, underdrive parts 5 are connected with insulation base plate 7 by connecting rod 4, stay-warm case 8 and well heater 10 cover on around graphite heat conducting piece 1 and polycrystalline silicon raw material and the crucible parts 9, and total system is contained on the work furnace chamber 6; Instantly after drive disk assembly 5 moves down by connecting rod 4 drive insulation base plates 7, insulation base plate 7 and stay-warm case 8 go out to form the heat radiation slit at A-A, carry out Homogeneouslly-radiating by novel graphite heat-conducting block 1, have reduced the transverse temperature gradient, make crystal plane be tending towards level, reach the requirement of ideal polysilicon solidification technology.
The utility model is simple in structure, and is easy to manufacture, and result of use is obvious, is widely used in the directional freeze system of solar energy polycrystalline silicon ingot casting system and metal alloy.
