The present application relates to a kind of high-voltage Schottky diode with vertical AlGaN / GaN heterojunction and its preparation method, the preparation method includes the following steps: one, epitaxial material growth;Two, re-growth groove production and re-growth;Three, cathode production;Four, dielectric layer growth;Five, anode production.It utilizes the 2DEG (two-dimensional electron gas) in vertical direction formed by re-growth, can significantly improve the forward current of diode;While utilizing the PN junction formed by re-growth, can uniformly disperse peak electric field, improve electric field concentration effect, improve breakdown voltage, and, when reverse, PN junction can be more effectively reduced reverse leakage than Schottky junction.

The utility model discloses an efficient heat dissipation dynamic voltage stabilizer which comprises a shell, a switch unit installed in the shell, a voltage stabilization unit installed in the shell and a fan installed in the voltage stabilization unit, the voltage stabilization unit is connected with the switch unit so as to open and close output through the switch unit, a window is arranged at the bottom of the shell, and the fan is arranged in the shell. A ventilation opening is formed in the position, corresponding to the window, of the pressure stabilizing unit, and a ventilation fence used for air outlet is further arranged on the side face of the pressure stabilizing unit. A partition plate is arranged in the shell and corresponds to the position between the voltage stabilizing unit and the switch unit, the switch unit is installed on the partition plate, the switch unit is surrounded by the inner wall of the shell and the partition plate and matched with the window to form a concentrated ventilation channel, and the fan is located at the position of a ventilation opening. And after starting, negative pressure is formed in the centralized ventilation channel to suck external air into the pressure stabilizing unit, and the external air is sent out from the ventilation grid after heat exchange in the pressure stabilizing unit. The heat dissipation efficiency can be improved, and the airflow centrality is improved.

The application discloses a BDO concentration system, which comprises a thick mash tower, a clear mash tower, a rectifying tower and a membrane assembly mechanism, wherein the thick mash tower and the rectifying tower are connected, the clear mash tower and the rectifying tower are connected, and the rectifying tower and the membrane assembly mechanism are connected. Part of mash liquid with high strain concentration is transported to the thick mash tower, and part of clear liquid with low strain concentration is transported to the clear mash tower. The thick mash tower works under negative pressure, the clear mash tower works under normal pressure, the rectifying tower works under pressure, and the membrane assembly works under low pressure. The BDO is concentrated by combining the thick mash tower, the clear mash tower, the crude wine tank and the membrane assembly mechanism in sequence, and the traditional distillation is organically combined with the inorganic membrane, so that the problem of BDO concentration difficulty in the existing production process is solved, the by-product BDO has good concentration effect and is easy to decompose, and the application can greatly meet the demand of the daily chemical industry on BDO.
