[0002] Cadmium telluride is an important II-VI compound semiconductor material with a zinc blende crystal structure, a direct transition band structure, a lattice constant of 0.6481nm, a bandgap of 1.5eV (25°C), room temperature electron mobility, room temperature hole mobility, and an electron effective mass of 0.096. During the preparation process of cadmium telluride crystals, a cooling device is required to cool the prepared crystals.

[0003] The cooling temperature of the existing cooling devices is mostly specified, with a small variation range. The cooling method for the workpiece is mostly to cool the workpiece quickly.

[0013] 1. By setting a feeding mechanism, when feeding, the rotating moving gear will slowly move to one end along the moving track, thereby driving the fixed plate to slide along the guide cavity to one end. In the process of the fixed plate sliding along the guide cavity to one end, the guide column blocks fixedly connected at the upper and lower ends of its surface will slide to one end along the guide grooves opened on the inner side of the guide cavity. When the moving gear moves to the arc corner of the moving track, it will drive the fixed plate to slide and get stuck to the front side of the slide plate, so that the guide column block fixed on one side of the fixed plate slides into the guide strip groove opened on the front surface of the slide plate. When the moving gear moves to the bottom of the arc corner, the fixed plate will drive the slide plate fixed on the outside of the guide strip groove through the guide column block fixed on one side and the guide strip groove engaged with the guide column block along the slide rod provided on the rear side to the inner side of the sliding cavity provided on the outside of the slide plate When the gear is moved to the bottom of the arc corner, the sliding plate connected to one side of the fixed plate will be driven to slide to the bottom of the inner side of the sliding cavity through the fixed plate provided on one side. At this time, the guide column block fixedly connected to the rear side of the fixed plate slides and is clamped on the limiting support hoop block provided at one end of the inner side of the guide strip groove. When the moving gear continues to move downward along the moving track, it will drive the fixed plate provided on one side to slide downward and slide into the guide groove opened in the middle of the bottom end of the sliding cavity, so that the moving gear moves slowly from top to bottom along the moving track, thereby driving the moving plate provided on one side of the moving gear to move slowly from top to bottom, so that the moving plate always remains parallel to the bottom end of the inner side of the mounting support plate during the process of moving from top to bottom, which facilitates the circulation and vertical pushing of the cadmium telluride crystals into the cooling chamber, which is beneficial to improving the feeding effect.

[0014] 2. By setting a cooling mechanism, during cooling, when the moving plate slides along the moving track driven by the moving gear to the hatch of the high-temperature cooling chamber composed of the top of the inner surface of the first L-shaped protective plate, the upper surface of the first layered partition plate, and the top of the inner surface of one end of the second L-shaped protective plate, the electric push-pull rod drives the fixedly connected sealed door to the contraction cavity provided on the inner side of the top of the second L-shaped protective plate, and the hatch is opened. Then, the moving plate is driven by the moving gear to move through the opened hatch to the high-temperature cooling chamber. The cadmium telluride crystals placed on the moving plate are initially cooled at high temperature by the temperature in the high-temperature cooling chamber that is lower than that of the cadmium telluride crystals. When the moving gear drives the moving plate to move downward from the high-temperature cooling chamber to the medium-temperature cooling chamber, When the top of the sealed door provided at one end of the top of the cooling chamber is reached, the sealed door fixed at one end is driven by the electric push-pull rod fixed in the first layered partition fixed on the inner side of the first layered partition into the contraction cavity opened on the inner side of the first layered partition, and the movable plate enters the medium-temperature cooling chamber for secondary cooling under the drive of the movable gear. When the movable plate moves from the medium-temperature cooling chamber to the low-temperature cooling chamber along the movable track under the drive of the movable gear, the cadmium telluride crystal placed on the movable plate is cooled tertiary by the low temperature in the low-temperature cooling chamber, which facilitates the step-by-step cooling of the cadmium telluride crystal, is beneficial to preventing large structural defects from appearing on the surface of the cadmium telluride crystal due to rapid cooling, and improves the cooling effect of the cadmium telluride crystal.

[0032] When the movable plate 23 slides along the movable track 21 driven by the movable gear 24 to the hatch of the high-temperature cooling chamber composed of the top of the inner surface of the first L-shaped protective plate 31, the upper surface of the first layered partition 33 and the top of the inner surface of one end of the second L-shaped protective plate 32, the electric push-pull rod 34 drives the fixedly connected sealed door 36 to move into the contraction cavity 317 provided on the inner side of the top of the second L-shaped protective plate 32 to open the hatch, and then the movable plate 23 is driven by the movable gear 24 to move through the opened hatch into the high-temperature cooling chamber, and the cadmium telluride crystals placed on the movable plate 23 are initially cooled at high temperature by the high-temperature cooling chamber, which is lower than the temperature of the cadmium telluride crystals.

[0033] When the moving gear 24 drives the moving plate 23 to move downward from the high-temperature cooling chamber to the top of the sealed door 36 provided at one end of the top of the medium-temperature cooling chamber, the electric push-pull rod 34 fixed in the first layered partition 33 fixed on the inner side of the first layered partition 33 drives the sealed door 36 fixed at one end to the contraction chamber 317 opened on the inner side of the first layered partition 33, and the moving plate 23 enters the medium-temperature cooling chamber for secondary cooling under the drive of the moving gear 24. When the moving plate 23 moves from the medium-temperature cooling chamber to the low-temperature cooling chamber along the moving track 21 under the drive of the moving gear 24, the cadmium telluride crystals placed on the moving plate 23 are cooled three times by the low temperature in the low-temperature cooling chamber.

8. The cooling device for preparing cadmium telluride crystal and the method for using the same according to claim 1, characterized in that: Method for using the cooling device for preparing cadmium telluride crystals: S1. Push the manufactured cadmium telluride crystal onto the upper surface of the movable plate, and use the suction cup provided on the upper surface of the movable plate to suck the cadmium telluride crystal; S2. Start the motor, and the motor drives the double-headed bevel gear rod fixedly connected to the output end to rotate. The rotating double-headed bevel gear rod drives the worm gear meshed on both the front and rear sides of one end to rotate. The rotating worm gear drives the pipe sleeve column rod fixedly connected to one side of the turbine to rotate through the meshing turbine at the top. The rotating pipe sleeve column rod drives the moving gear fixedly connected to one side to slowly move toward one end along the moving track. S3, when the moving plate slides along the moving track under the drive of the moving gear to the high-temperature cooling chamber formed by the top of the inner surface of the first L-shaped protective plate, the upper surface of the first layered partition plate, and the top of the inner surface of one end of the second L-shaped protective plate, the cadmium telluride crystal placed on the moving plate is initially cooled at high temperature by the temperature in the high-temperature cooling chamber which is lower than that of the cadmium telluride crystal; S4. When the moving gear moves to the arc-shaped corner of the moving track, it will drive the fixed plate provided on one side of the moving gear to slide to the front side of the slide plate, so that the guide column block fixed on one side of the fixed plate slides into the guide groove provided on the front surface of the slide plate. Under the restriction of the slide plate, the moving gear will drive the moving plate to slide vertically into the medium-temperature cooling cabin for secondary cooling. S5. The moving gear continues to drive the moving plate to slide downward along the moving track. When the moving plate slides from the medium-temperature cooling chamber into the low-temperature cooling chamber, the temperature in the low-temperature cooling chamber cools the cadmium telluride crystal three times to complete the step-by-step cooling.
