[0002] The Czochralski method is a commonly used method for growing single crystals at present. Its working principle is to place the raw materials constituting the crystal in a crucible and heat them to melt. A seed crystal is picked up on the surface of the melt, and under controlled conditions, the seed crystal and the melt continuously rearrange atoms or molecules at the interface, and gradually solidify with the decrease in temperature to grow a single crystal. With the increasingly rapid development of the industry, the improvement of each thermal field component has reached a bottleneck, but there has been no major change in the water-cooled screen. This patent is for the transformation of the water-cooled screen, which is used to increase the upper limit of the pulling speed and improve the temperature gradient at the water-cooling position, so as to achieve the purpose of reducing costs and increasing efficiency. Therefore, a heat pipe type water-cooled screen is proposed. Content of the Utility Model

Heat pipes are evenly distributed on the inner side surface of the water-cooled screen. Connecting pipes are connected to both sides of the water-cooled screen. A lifting plate is arranged in the middle of the connecting pipe. A liquid inlet pipe is connected to the end of the connecting pipe.
[0005] Preferably, the connecting pipe and the liquid inlet pipe are vertically arranged, and the axial direction of the liquid inlet pipe is parallel to the axial direction of the water-cooled screen.
[0006] Preferably, a plurality of notch structures are arranged on the lifting plate, and the lifting plate is a plate structure.
[0007] Preferably, the upper end of the heat pipe is welded and fixed on the inner side surface of the water-cooled screen, the lower end of the heat pipe is set away from the inner side surface of the water-cooled screen, and the heat pipe is made of a stainless steel shell.

[0009] Preferably, a heat exchange groove is arranged on the inner wall of the water-cooled screen, the heat exchange groove is annularly arranged, and the heat exchange groove is connected to the connecting pipe.
[0010] The beneficial effects of the utility model are:
[0011] Based on the original water-cooled screen, the utility model evenly inlays 6 heat pipes on the inner side. The heat pipes make full use of the principle of heat conduction and the rapid heat transfer property of the refrigeration medium, and transfer the heat of the heating object to the outside of the heat source through the heat pipes, solving the problem of the low heat load of the water-cooled screen in the background technology; adopting a stainless steel shell plus a sodium refrigeration medium can ensure operation under the working condition of 1200 °C; the condensation side of the heat pipe is welded to the inner wall of the water-cooled screen, and the heat pipe is not connected to the water-cooling. The evaporation side is located at the lower part of the water-cooling and is used to assist the water-cooling in heat dissipation. Description of the Drawings
