A fuel cell module with water and thermal management function comprises a fuel cell stack, a distribution unit, a power management unit, a voltage reducing and heating submodule, a liquid water management submodule, an outer package submodule and other parts. The distribution unit distributes the hydrogen, air and a cooling medium which enter the modules into each stack; the power management unit carries out state detection and management on the modules and controls the connection and disconnection of power output; the voltage reducing and heating submodule regulates the temperature of the fuel cell stack and controls the output voltage; the liquid water management submodule separates liquid water from the hydrogen and the air which enter the fuel cell stack module and discharges the liquid water at the hydrogen side; and the outer package submodule realizes waterproof and dustproof and heat preservation of the fuel cell stack module and discharges the hydrogen and steam in the package module. One advantage of the invention is that the fuel cell module can rapidly enter an ideal working state, thereby being beneficial to improving the performance, stability, safety and the like of the fuel cell module.

The invention relates to an industrial liquid vaporization method and equipment thereof, in particular to a vaporization method of vaporized petroleum liquid and equipment thereof. In the method, an electric heating chassis is used for heating the vaporized petroleum liquid in a vaporization tank; the heating temperature of the electric heating chassis is between 150 DEG C and 300 DEG C; an electric heating base is used for heating a gas collecting pipe; and the heating temperature of the electric heating base is higher than the vapor temperature of the vaporization tank by 10 DEG C to 20 DEGC. The equipment comprises a reservoir cylinder, the vaporization tank and the gas collecting pipe, wherein the lower part of the vaporization tank is provided with the electric heating chassis bonded with the bottom; the lower part of the gas collecting pipe is provided with the electric heating base bonded with the bottom; and the electric heating chassis and the electric heating base are both internally connected with a temperature sensor. In the invention, the electric heating chassis and the electric heating base are directly used for heating to avoid transferring heat through a medium; during heating, the electric heating base and the electric heating chassis are started only; after the temperature reach a set temperature, the electric heating base and the electric heating chassis can be conveniently controlled for stopping heating; the pressure and the temperature are adjustable and controllable; the heating efficiency is high; the heat transfer delay is slight; and the equipment is simplified.

The invention belongs to the field of magnetron sputtering, and particularly relates to a target-sputtering self-circulating cooling device for the target cooling technology. The device comprises a target and a cooling structure. The target is cooled through a synthetic jet method. The target is connected to the upper end of a metallic cathode in a butt joint manner and sealed at the upper end of the metallic cathode. A synthetic jet generator is fixed in a synthetic jet cavity to generate intermittent jetted gas. The jetted gas is stored through the synthetic jet cavity and is sprayed out along a spray nozzle. The sprayed jetted gas impacts on fins on the inner side of the target to achieve the cooling effect, the gas obtained after temperature rise enters a cooling passageway, and the cooled gas returns to the synthetic jet cavity again to be recycled.

The invention provides a solid and liquid combined fermentation vinegar brewing method, which comprises: fermented fermentation broth is mixed with bran and bran coats, inoculated with acetobacter, aroma-producing yeast and lactobacillus to become a solid fermentation substrate of vinegar, and sent into a fermenter for acetic fermentation, and juice generated by fermentation of inoculated materials flows into the bottom of the fermenter from gaps between barriers; when the fermentation temperature of the solid fermentation substrate of the vinegar is overhigh, crude vinegar in a crude acetatepool is cooled and refluxed and poured into the solid fermentation substrate of the vinegar on the top layer, and simultaneously a vent hole is opened, so as to achieve the aims of oxygenation and temperature reduction of the solid fermentation substrate of the vinegar; and when the fermentation temperature in the solid fermentation substrate of the vinegar is too low, the crude vinegar in the crude acetate pool is heated and refluxed and poured into the solid fermentation substrate of the vinegar, so as to realize temperature rise of the solid fermentation substrate of the vinegar. The solidand liquid combined fermentation vinegar brewing method combines the advantages of solid fermentation vinegar brewing and liquid fermentation vinegar brewing, has the advantages of high acid yield and good flavor, mouthfeel and quality of the vinegar, can control the fermentation temperature of the solid fermentation substrate of the vinegar, and can brew the vinegar all the year around.
