Abstract

The vibrating non-isothermal liquid bridge generator solves the problem that the existing liquid bridge generator only has a shear air flow type and an external magnetic field type. The vibration-type non-isothermal liquid bridge generator of the present invention includes a liquid bridge generating device, a vibration device and a temperature control device; in the liquid bridge generating device, the upper plate assembly is threadedly connected with the upper bridge seat through a threaded shaft, and the sliding shaft of the lower plate assembly is inserted into the Connected in the lower bridge base, the upper and lower plate assemblies, the vertical centerlines of the upper and lower bridge bases are located on the same vertical line; the vertical vibrator in the vibrating device is installed on the top of the outer support, and the horizontal vibrator is installed on the side of the outer support. part; the heating plate in the temperature control device is installed in the heating tank of the upper plate assembly, and the cooling plate is installed in the cooling tank of the lower plate assembly. The liquid bridge generator of the present invention can realize the vertical and horizontal vibration of the liquid bridge, and can adjust the vibration frequency and amplitude, effectively suppress the oscillating Marangoni convection inside the liquid bridge, and have significant guiding significance for the preparation of single crystal by the floating zone method.

Description

Technical field [0001] The present invention belongs to the field of fluid physics, and more particularly to a non-destentive liquid bridge generator. Background technique [0002] The floating zone method is a common method of preparing a semiconductor crystal material. The main principle is that the feed rod is pulled in the annular heater, the solid feed material located in the vicinity of the annular heater is heated to form a melting zone, and the melting area is left away from the heater. Cool crystallization. The mass convection effect of the growth of the crystal is subjected to the mass convection of the Marangoni in the melting zone, which produces micrometer impurity stripes, which seriously affects the quality of the crystal preparation. The liquid bridge is based on a floating zone method for a single crystal as a project, and the upper disk is thermally simulated an annular heater. The following disk cooling the physical experiment model of the simulated feed rod is...
