The thermal resistance of the winding finned tube is relatively low: after practice, it is concluded that the thermal resistance of the bimetallic winding finned tube is basically zero even if it is used in an environment of 210 °C, because the relatively Low thermal resistance to touch force, so its effect on heat transfer is very good.
Winding finned tube application: mainly used in industrial and civil heating radiators and air heaters for drying materials
K L-type finned tube Working temperature: 230℃ Features: The winding process is adopted, with excellent production efficiency, uniform fin spacing, good heat transfer, high finning ratio, and the base tube can be protected from air erosion. Application: Mainly used in air coolers in petrochemical, electric power, papermaking, building heating and other industries, air heaters and air heaters in food industry, starch and other spray drying systems.

On the 18th, in the Memorial Hall of the Anti-Japanese War in Chuzhou City, Sichuan Province, a girl was busy explaining to visitors the glory days of the year. During the "September 18" commemoration event, many tourists came to the Anti-Japanese War Memorial Hall in search of the footprints of the Anti-Japanese War and remembered the national shame.
Located in Tianxian Town, Naxi District, Bozhou City, the Anti-Japanese War Memorial was originally a primary school. It was built in 1940. It has a courtyard structure with a courtyard in the middle. The courtyard is flanked by school buildings and there are more than 20 stone roofs. In the era of anti-Japanese war, it was also known as "Anti-Japanese Primary School." In addition to the teaching of Chinese language, mathematics, and physics and chemistry, the primary school of the Anti-Japanese War was also specifically equipped with military training courses. Students go out to work sooner or later and run off-road once a week. In addition, the school also offers martial arts, swords, shooting and other military training subjects. The instructors are local military officers stationed in the defense.
It is understood that in September 1939, the Nationalist general and Li Tao, the founder of the Chinese Chemical Corps, was instructed to lead the Chemical Corps to Sichuan and secretly moved from Yichang to Naxi in Zhangzhou in December of that year. The headquarters of the Corps Commander was stationed at Naxi City, and the ordnance department, chemical library, and laboratory were located in the present Nianxi Tianxian Huaibeixi. After Li Jintao led the Chemical Corps to enter Naxi, he took full advantage of the local geographical conditions and increased the development and testing of chemical weapons. In 1942, Li Ningtao led the Chemical Corps Corps to participate in major battles in the Burma battlefield and successively wiped out many of the Japanese elite. In September 1944, Li Ningtao was attacked by four Japanese warplanes on the way back to China and was unfortunately a country.
Due to the long time ago, the school has moved out as a whole, and the original site has been listed as a cultural relic protection unit in Sichuan Province. In order to fully demonstrate the anti-Japanese heroic deeds of the people from all walks of life in the city during the war of resistance against Japan, this year, Naxi District, Bozhou City will also expand the expansion of the Anti-Japanese War Elementary School to the Anti-Japanese War Memorial in Chuzhou City, Sichuan Province.

"Russia and France have people coming. They are very friendly. When they enter the memorial hall, they have to take a nap. They shook hands with me and said in shrill Chinese, 'Hello, hard!'" Gao Tongmin said, "I hope Japan The public can also visit and understand and objectively view the history."
The memorial hall also added a special “Diaoyudao†exhibition hall, collected a large amount of historical data and pictures, and gave detailed introductions on the historical background, disputed focus, and ownership of the Diaoyu Islands, so that people from all walks of life who came to visit fully learned about the Diaoyu Islands.

During the visit, the enthusiasm of the narrators attracted many tourists and made the exhibition hall a popular place for the entire exhibition hall.
