Both are available. According to the Popular Science China query.
1. Air-cooled generator: Use one or more large fans to force air toward the generator body to dissipate heat. Its advantages are simple structure, easy maintenance and no risk of freezing, overheating and boiling. The generator set is limited by thermal load and mechanical load, has low power, and the power conversion rate of the generator set is also low, which is not energy efficient enough. The air-cooled machine should be installed in an open cabin, which has high environmental requirements and high noise reduction treatment in the engine room. The air cooling method is more commonly used in small gasoline generators and low-power diesel gensets.
2. Water-cooled generator: water circulatesre the inside and outside of the body, and the heat generated inside the body is discharged through the water tank and the fan. Both functions are to dissipate heat. the air, and there is no difference in use. The advantages of water-cooled units are ideal cooling effect, rapid and stable cooling and high power conversion rate of the unit itself. The water-cooled unit has small limitations on the installation site, low environmental requirements, low noise, and can also implement remote cooling system. Water cooling method is used in small diesel generators and high-power diesel gensets.
Your product is the third generation rare earth permanent magnet material NdFeB. This product has a promising future. It is one of the important basic materials that support the industryof modern electronic information and is closely related to people's lives. The demand for high-performance rare earth permanent magnet materials in sectors such as computers, mobile phones, automobiles, telephones and the electric automobile industry is increasing rapidly. In 1998, the global production of NdFeB (including sintered magnets and bonded magnets) reached 11,300 tons, and the annual growth rate has remained above 30% in recent years.
Rare earth permanent magnet materials are mainly used in various micromotors, as well as nuclear magnetic resonance equipment, magnetic separation equipment and magnetic machines that need to generate strong spaced magnetic fields .
Your company's products have broad prospects, but good prospects do not mean making money. When you start a businesse, you should pay attention to the construction of the enterprise trinity: ① raw material supply channels ② your own production management system. ③ stable sales channels; except for ② internal factors, ① raw material purchasing and ③ product sales all depend on their own intelligence capabilities (the ability to comprehensively collect and use relevant industry information) , that is, borrowing from external sources. The best way to resolve these two aspects is as follows: a factory-factory alliance, becoming a part of the relevant industrial chain, has many advantages that I will not go into detail here.
I have relevant information on RuFeB production companies. If you have the ability to produce boron alloys, take a look: Boron production companies ① Yingkou Advantages: Many companies have a chigh production capacity. Disadvantages: Made with the highest purity at 98%, ② Baoding Zhong Puruituo Advantages: Purity 99% Disadvantages: Little reputation, average production capacity ③ Beijing Nonferrous Metals Research Institute Advantages: High reputation, purity 99 % Disadvantages: Low production capacity ④ Guangzhou Ruihe Chemical Advantages: Purity 99% Disadvantages: It is not the main product with low production capacity
No need to mention those that produce iron
There are only a few companies in China that produce rubidium. The ones I know. are Xinjiang Nonferrous Metals Research Institute, Beijing Pan DECHEN TECHNOLOGY LIMITED. Don't Trust the CompanyIndustry Promotional Language: The only one. There can only be one manufacturer in China. The biggest possibility is that manufacturers can rarely be calculated in single digits. Secondement, it should be noted that there are many online trading companies. are too high, they will negotiate.
