Technical Field
[0001] The utility model relates to a crystal growth auxiliary furnace chamber, in particular to a crystal growth furnace auxiliary furnace chamber with a split cooling cavity. Background Art
[0002] When the crystal growth furnace is growing crystals, the cooling device needs to be lifted up and down in the auxiliary furnace chamber, and the lifting mechanism of the cooling device needs to be installed outside the auxiliary furnace chamber. Therefore, two cavity spaces need to be set on both sides of the auxiliary furnace chamber to install the lifting device of the cooling device.
[0003] In the prior art, the cooling chamber is generally an integral welded structure, that is, the cooling chamber is directly welded to both sides of the auxiliary furnace chamber, which has problems such as difficulty in processing and manufacturing, and difficulty in controlling the connection accuracy, and is prone to structural deformation, affecting production. Utility Model Content
[0004] The utility model provides a crystal growth auxiliary furnace chamber with a split cooling cavity, which aims to overcome the above-mentioned deficiencies in the prior art, effectively reduce the difficulty of processing and manufacturing, and improve the connection accuracy.
[0005] The technical solution of the utility model is: a crystal growth auxiliary furnace chamber with a split cooling chamber, the structure of which includes an auxiliary furnace chamber body and a cooling chamber, a pair of cooling chambers are detachably connected to both sides of the auxiliary furnace chamber body, and the cooling chamber and the auxiliary furnace chamber body are not welded. After the lifting mechanism of the cooling device in the auxiliary furnace chamber body is installed, the cooling chamber is fixed on the outside of the lifting mechanism in a non-welding manner to complete the installation of the overall structure.
[0006] Preferably, rectangular step surfaces that bulge outwards and whose centers are connected to the inner side of the auxiliary furnace chamber body are respectively provided on both sides of the auxiliary furnace chamber body, and a rectangular connecting surface that bulges outwards and whose centers are connected to the inner side of the cooling cavity is provided on one side of the cooling cavity. The step surface and the connecting surface match in shape, and the step surface and the connecting surface are aligned and evenly fixedly connected along the contact surface by a number of connecting bolts.
[0007] Preferably, an O-ring is provided between the step surface and the connecting surface to ensure sealing.
[0008] The advantages of the utility model are as follows: the structural design is reasonable, the cooling chamber adopts a split design and is connected to the auxiliary furnace chamber by bolts. Compared with the overall welded structure, it can effectively reduce the difficulty of processing and manufacturing, ensure connection accuracy, avoid structural deformation, and ensure production stability.
