The brazed Plate Heat Exchanger (BPHE) is a type of heat exchanger construction in which metal plates with flat surface offer an effective and efficient method of heat transfer. These plates are joined together by brazing (mainly copper), typically stainless steel. Due to the close contact between the two surfaces, there is a very high heat transfer coefficient, leading to a low overall unit size. They therefore provide much greater efficiency than a Shell And Tube Heat Exchanger.
Brazed Plate Heat Exchangers are widely used in air-conditioning and refrigeration, power generation, and other process applications. For example, within a cooling cycle, a BPHE can be used to transfer heat from one fluid to another. Typical fluids in such coils and systems are either glycol or water. In a power system, a BPHE can be used to cool oils, recirculating lubricants, fuels, and other fluids.
The major advantages of BPHE are their compact size, efficient heat transfer and minimal pressure loss. BPHEs also have low maintenance requirements and a long service lifetime. Furthermore, because of their flat surface design, BPHEs have no patterns or turns and thus lower energy costs and minimize fouling. Finally, the material used in BPHEs makes them resist to corrosion and heat, making them ideal for high temperature and hostile environments.

Recently, news came from the Xinjiang cotton area. The newly developed baler of China's Guizhou Fenglei Aviation Ordnance Co., Ltd. was well received by the users of the Construction Corps.
A military industrial enterprise located in the Guizhou Plateau, how to develop and produce cotton production and processing equipment needed by the Xinjiang Construction Corps thousands of kilometers away?
The reporter went to the interview and learned that this is the result of the development of high-tech equipment by Fenglei Company in recent years, relying on the advantages of military resources, aiming at the needs of industrial development, taking the road of military-civilian interaction, cooperation and innovation.
Cotton production gives birth to big business opportunities
China's rapidly developing cotton industry calls for accelerating the pace of mechanized production.
At present, China's annual cotton planting area is 80 million mu, accounting for nearly one-third of the planting area of ​​Xinjiang this year, planting area of ​​more than 20 million mu. The Xinjiang Production and Construction Corps is the main force in China's cotton production. The scientific and technological content and technical means in the cotton production process ranks among the top in the country. However, the problem of “difficulties in picking up flowers†​​and the cleaning and processing of cotton machine picking and manual picking have become a “bottleneck†that hinders the development of Xinjiang Construction Corps and even China's cotton industry.
Relevant experts believe that China's cotton production is mechanized in the whole process, and it has not yet entered a period of large-scale expansion. The next 10 years will be the best development opportunity.
The huge cotton industry development needs are forming a huge market. Xinjiang, especially the production and construction corps that accounts for 40% of the cotton planting area in Xinjiang, in order to solve the bottleneck of the cotton industry's large-scale and intensive management development, in order to improve the industrial science and technology content, in recent years, it has gradually turned from manual picking to mechanical picking. . The cotton production machinery market formed by this transformation has provided huge business opportunities for related enterprises at home and abroad.
It is understood that the opinion of the Xinjiang Construction Corps on the promotion of the “Eleventh Five-Year Plan†machine for cotton picking proposes that by the end of the “Eleventh Five-Year Planâ€, the entire corps will realize a total mechanized area of ​​5 million mu of cotton, accounting for 58% of the cotton planting area of ​​the Corps. . The total investment in machine cotton mining technology is expected to be more than 4.3 billion yuan, of which the planned refining machine cotton cleaning and processing production line plans to invest 1.77 billion yuan.
Many foreign companies have smashed into the big market of China's cotton machinery manufacturing, and companies have entered or stepped up. Faced with expensive foreign cotton picking and processing machinery, China's cotton production enterprises are looking forward to the early use of high-quality domestic cotton pickers and cotton processing machinery with good cost performance.
Guizhou Plateau
In the face of huge cotton machinery market opportunities, domestic equipment manufacturing companies are also actively involved.
Following the successful development and production of the “Pingshui Brand†large-scale self-propelled cotton picker of China Aviation Industry Corporation of China Aviation Industry Group Pingshui Machinery Co., Ltd., after breaking the monopoly position of foreign cotton production equipment in China, it is also the wind and thunder company of China Aviation Industry Corporation of Guizhou Airlines. Follow up immediately.
However, in the face of huge enticing business opportunities and fierce competition between domestic and foreign strong hands such as Lin, what does Fenglei people rely on to win?
Fenglei Company, which has strong military resources and strong talents, technology and equipment strength, is located on the edge of the famous Huangguoshu Waterfall in Guizhou Plateau. It is rarely known for its military background.
The reporter learned that Fenglei Company is mainly engaged in the specialized scientific research and production of aviation ordnance external devices. Since the factory moved to Guizhou Anshun in the 1970s due to the construction of the third line, after more than 30 years of construction and development and the hard work of several generations of wind and thunder, Fenglei has developed into a modern enterprise with scientific research, trial production and mass production capacity. It has undertaken the production and development tasks of the main models of the country and a number of key models.
Fenglei Company is a national second-level measurement unit. With the high level of strength in scientific research, production and quality management, it has obtained a series of scientific research and production qualifications from the National Defense Science and Technology Commission and the General Armament Department. The results successfully passed the acceptance of the “First-class Environmental Construction†(6S) management of China First Airlines.
