Abstract
The utility model relates to a connector sealing structure of a water-cooling disc of a quasi-monocrystalline silicon ingot furnace. The connector sealing structure is characterized by comprising the water-cooling disc which is arranged at the bottom of the ingot furnace, wherein a water inlet threaded hole and a water outlet threaded hole are formed in the water-cooling disc, cooling water outside the ingot furnace is injected into the water-cooling disc via a brass adapter to form a circulating cooling structure, an annular groove is formed in the connecting matching surface of the brass adapter and the water-cooling disc, and a sealing ring is arranged in the annular groove. By arranging the annular groove on the matching surface of the adapter to place the sealing ring, when the adapter is installed, the sealing ring can be protected from damage to ensure the sealing effect of the sealing ring; at the same time, the sealing effect of brass materials is used to form multiple sealing effects so as to ensure water channels to be sealed under vacuum environment and ensure water not to be leaked.
Description
Technical field
The utility model relates to a kind of aqueous cold plate interface sealing structure of accurate single-crystal ingot casting furnace.
Background technology
At present, sun power mainly makes by vertical pulling method with silicon single crystal, also have now by casting manufacture order crystal silicon, its method is to add seed crystal in the bottom of crucible, on seed crystal, load again silicon material, in the process of silicon raw material fusing, control the fusing of seed crystal, make a part for seed crystal or seed crystal remain solid-state, in cooling process, quasi-monocrystalline silicon is along the crystal orientation crystallization of seed crystal, the defect concentration of the crystal that this method is produced is lower, the fusing mode of this method of the while also coating of the inside to crucible is had higher requirement, indirectly increased cost, therefore in order to address these problems the device that need to prepare casting monocrystalline silicon to directional solidification method, carry out structural improvement, existing by polycrystalline silicon ingot or purifying furnace transformation being applicable to the Foundry Production of silicon single crystal, the sealing of original aqueous cold plate water route mostly is raw material band thread seal, this sealing is not attractive in appearance, the shortcoming such as leak in addition, adopt in addition the sealing of gasket, gasket breakage when misoperation, also can produce and leak.
Utility model content
Technical problem to be solved in the utility model is to provide the aqueous cold plate interface sealing structure of the accurate single-crystal ingot casting furnace of water route sealing under a kind of vacuum environment.
For solving the problems of the technologies described above, the utility model provides a kind of aqueous cold plate interface sealing structure of accurate single-crystal ingot casting furnace, it is characterized in that: comprise the aqueous cold plate that is arranged on ingot furnace bottom, on described aqueous cold plate, offer into water threaded hole and water outlet threaded hole, the water coolant of ingot furnace outside is injected into aqueous cold plate by brazed joint, form circulation cooling mechanism, described brazed joint is connected mating surface place and is provided with cannelure with aqueous cold plate, be provided with sealing-ring in cannelure.
By the mating surface place at joint, cannelure is set and places sealing-ring; can be when erection joint; protection sealing-ring is not damaged; guarantee the sealing effectiveness of sealing-ring; utilize the self seal effect of copper product to form multiple-sealed effect simultaneously; guarantee water route sealing under vacuum environment, guarantee that water can not leak.
Below the aqueous cold plate interface sealing structure of a kind of accurate single-crystal ingot casting furnace described in the utility model is further optimized:
Described aqueous cold plate preferably adopts T2 copper.
Described joint preferably adopts H62 brass.
It is mutually concordant with aqueous cold plate inner bottom surface that described water supply connector extend into end face in aqueous cold plate.
Described water out adapter extend into end face in aqueous cold plate higher than aqueous cold plate inner bottom surface, and in end, is provided with a tapered cut.
Described sealing-ring preferably adopts rubber sheet gasket.
Accompanying drawing explanation
Fig. 1 is the aqueous cold plate interface sealing structure schematic diagram of this accurate single-crystal ingot casting furnace.
Fig. 2 is the aqueous cold plate interface sealing structure partial enlarged drawing I of this accurate single-crystal ingot casting furnace.
Embodiment
Below by embodiment and accompanying drawing, this device is described in further detail:
Referring to Fig. 1, a kind of aqueous cold plate interface sealing structure of accurate single-crystal ingot casting furnace, comprise the aqueous cold plate 1 that is arranged on ingot furnace bottom, described aqueous cold plate 1 preferably adopts T2 copper, aqueous cold plate 1 has multiple cavity volumes, two different cavity volumes places on aqueous cold plate 1 are provided with into water threaded hole and water outlet threaded hole, a general preferred symmetrical position at a symmetrical cavity volume arranges water inlet threaded hole and water outlet threaded hole, the brazed joint that the water coolant 2 of ingot furnace outside is threaded connection is injected into aqueous cold plate 1, form circulation cooling mechanism, described brazed joint preferably adopts H62 brass, described brazed joint structure is similar to pipe joint structure, two ends have external screw joint and middle part and have location shoulder block and form to locate with aqueous cold plate outerplanar and coordinate, referring to Fig. 2, described brazed joint location shoulder block is connected mating surface place and is provided with cannelure with aqueous cold plate, in cannelure, be provided with sealing-ring 4, described sealing-ring 4 preferably adopts rubber sheet gasket, and in order to reach good refrigeration cycle effect, it is mutually concordant with aqueous cold plate 1 inner bottom surface that described water supply connector 5 extend into end face in aqueous cold plate 1, described water out adapter 3 extend into end face in aqueous cold plate 1 higher than aqueous cold plate 1 inner bottom surface, and in end, be provided with a tapered cut, by the mating surface place at joint, cannelure is set and places sealing-ring, can be when erection joint, protection sealing-ring is not damaged, guarantee the sealing effectiveness of sealing-ring.
The sealing principle of sealed structure is that elastic deformation can occur such screw thread contact surface of T2 copper aqueous cold plate 1 when screw thread screws, and plays first sealing function; Rubber sheet gasket 4 also can be crushed out of shape, and plays second sealing function; The outmost turns of H62 brazed joint and T2 copper aqueous cold plate 1 close contact, play three seals effect, has like this three sealing functions, and under vacuum environment, water just can not leak, and has guaranteed the requirement of vacuum tightness.
