The application discloses a cutting synergist for liquefied petroleum gas and a preparation method thereof, and belongs to the technical field of cutting synergists. The cutting synergist is prepared by mixing the following components with the mass content: an alkyl ferrocene mixture 5-8%, n-octane 6-10%, ethylene glycol monoethyl ether 8-10%, isooctyl nitrate 10-15%, acetone 15-25%, and 200# solvent oil 25-45%. The application is a high-efficiency energy-saving synergist for cutting liquefied petroleum gas, and the performance of the liquefied petroleum gas after the addition of the synergist can reach and exceed the cutting performance level of the original petroleum gas and acetylene gas, and the liquefied petroleum gas can completely replace acetylene gas, natural gas and pure propane to be used as industrial gas for metal cutting. The product performance exceeds that of natural gas, industrial propane and the same kind of synergists on the market, and has a wide application prospect, and is a great breakthrough of industrial gas in the industrial field of China.

The invention discloses a composite phase change heat storage material as well as a preparation method and application thereof, and belongs to the technical field of phase change heat storage materials. The invention discloses a composite phase change heat storage material which is prepared from the following components in percentage by mass: 50%-75% of a phase change core material, 20%-45% of a porous carrier matrix and 3%-10% of a heat conduction reinforcing agent, the porous carrier substrate is diatomite; the heat conduction reinforcing agent is expanded graphite. The technical problem that an existing phase change heat storage material is difficult to have high heat storage density, excellent shaping effect, high heat conductivity and good mechanical property at the same time is remarkably solved.

The application relates to the technical field of heat storage, and discloses a heat exchange device for a heat storage system, which comprises a heat storage box filled with first solid heat storage materials; metal plates embedded in the first solid heat storage materials, the metal plates being distributed at equal intervals in a vertical direction, the metal plates being filled with second solid heat storage materials; and heat exchange pipes penetrating through two ends of the heat storage box in the vertical direction, the first solid heat storage materials defining heat exchange flow channels in the vertical direction, the metal plates being integrally formed with metal rib plates in regions overlapping with the heat exchange flow channels, the metal rib plates being provided with through holes in the centers, and the heat exchange pipes being arranged in the through holes; wherein, in a heat release direction, the pipe diameter of the heat exchange pipes and the hole diameter of the through holes gradually decrease. The heat exchange device can effectively reduce the gap proportion in the heat storage device, improve the heat storage density, improve the heat transfer effect of the heat exchange device, and ensure uniform heat release.
