When the relay generates excessive heat, can directly through liquid cooling board and carry out rapid cooling, will not exceed the long -term tolerance temperature of relay shell, prolongs the service life, effectively solved because of the burn -off or welding phenomenon that the temperature of the lap joint is too high, makes the main circuit virtual connection or circuit breaking, leads to the problem of the instantaneous power failure or the fire of the vehicle.

The invention discloses a support plate stabilizer structure for enhancing fuel oil atomization and suitable for an afterburner, which is used for improving the fuel oil atomization effect and the combustion stability, and comprises two support plate outer edge frames, a support plate tail edge frame, a fuel oil injection rod and the like, and a support plate mixing channel is formed between the two support plate outer edge frames; and a plurality of cooling air cavities are formed in the main body part so as to prevent key parts from being ablated in a high-temperature environment. First fuel oil impacts the fan-shaped channels through the oil injection holes to form an oil film, is further atomized under the shearing action of airflow and is mixed with air, and premixed gas is formed and then enters the concave cavity to be combusted. According to the design, flames in the concave cavity can be kept stable under the extreme conditions of low temperature, low pressure and the like, so that the ignition and flameout boundary of the combustion chamber is widened, meanwhile, high-temperature fuel gas in the concave cavity can heat transverse jet flow of second fuel oil, and the evaporation and mixing efficiency of the second fuel oil is improved. By means of the integrated design, the number of components is reduced, the flow resistance in the non-stress-application state is reduced, and meanwhile the thrust-weight ratio is increased.

This invention relates to the field of carbon nanotube technology, and discloses a method and apparatus for preparing horizontally arrayed carbon nanotubes. A gaseous carbon source is used as the reactant, and transition metal vapor is used as the catalyst. The preparation is carried out using an electric arc discharge method. The electric arc is located between two energized electrodes in a reaction vessel, with the two electrodes positioned vertically opposite each other. The catalyst powder is magnetically attracted to the bottom of the upper electrode. When struck by the electric arc, the catalyst powder heats up, loses its magnetism, and falls, contacting the electric arc in the air and vaporizing. This not only ensures more thorough contact with the arc, generating more transition metal vapor, but also changes the vapor generation location from a single point on the electrode to the entire electric arc. The reaction location completely coincides with the transition metal vapor generation location, thus overcoming the problem of catalyst absence at some reaction sites. Simultaneously, the electric arc rotates in the magnetic field rather than being fixed at the same position on the electrode, and the contact area with the reactant is larger, overcoming electrode ablation problems and improving reaction efficiency.

This invention discloses a forced lubrication and circulating cooling system and method for a gearbox. The system includes a gearbox body and a gear oil pump driven by a shift shaft within it. The oil pump draws oil from the bottom of the gearbox through an oil suction pipe and an oil suction filter, pressurizes it, and sends it to an oil cooler for cooling via a first return oil pipe, and then to the brake shaft via a second return oil pipe. The brake shaft has a main oil passage axially, a flow-limiting plug at one end, and radial branch oil passages circumferentially. A brake gear is fitted on the brake shaft, and its internal gear oil passages communicate with the radial branch oil passages, guiding the cooling oil into the brake friction pairs. Cross-shaped mesh oil grooves on the friction pad surface increase the heat exchange area. After lubrication and cooling, the oil flows back to the bottom of the gearbox, forming a closed loop. This system achieves forced lubrication and efficient heat dissipation, solving the problems of brake overheating and wear. It has a compact structure and low cost, and is particularly suitable for tracked agricultural machinery.
