The finned tube is to improve the heat exchange efficiency. By adding fins on the surface of the heat exchange tube, the outer surface area (or inner surface area) of the heat exchange tube is increased, so as to achieve the purpose of improving the heat exchange efficiency. Such a heat exchange tube . Usually used for heat exchange between liquid and gas.
Finned tube is a heat exchange element. As a heat exchange element, finned tubes usually work under high-temperature flue gas conditions for a long time. For example, the finned tubes usually used in boiler or harsh environments, high temperature and high pressure, and in a corrosive atmosphere. This requires that the finned tubes should have high anti-corrosion properties, Anti-wear properties, lower contact resistance, higher Stability and anti-dusting ability.
There are many types of finned tubes, and new varieties are constantly emerging. According to the classification of processing technology, there are extruded fin tube; high frequency welded finned tubes; rolled formed finned tubes; suit formed finned tubes ; cast finned tubes; tension wound finned tubes; Inserted tubes.
According to the shape of the fins, there are square finned tubes; circular finned tubes; spiral finned tubes; longitudinal finned tubes; corrugated finned tubes; spiral serrated fins Helical Serrated Finned Tubes; pin-shaped finned tubes; integral plate-shaped finned tubes; inner finned tubes.
According to whether the fin material of the finned tube is the same as that of the base tube, it can be divided into: single metal finned tube, bimetallic composite finned tube.
Single metal finned tubes are classified by material into copper finned tubes; aluminum finned tubes; carbon steel finned tubes; stainless steel finned tubes; cast steel finned tubes.

Recently, the "JMC Light Truck Low-Carbon China Tour and the National Tour Fuel-Saving Experience Camp" activities came to the only "National Ecological Culture Village" in Hubei Province - the Pomegranate Resort in Cihui Street, Dongxihu District, Wuhan.
Grenadines Resort has built parking sheds, roofs and curtain walls with solar power generation functions. It integrates solar power stations and buildings, and lays out 8000 square meters of solar photovoltaic panels with an annual power generation capacity of 1 million kilowatt-hours. 237 households lived on electricity. Compared with thermal power projects, the annual savings of 345.6 tons of standard coal, annual emissions of carbon dioxide, sulfur dioxide and other pollutants of 950 tons, with good energy-saving emission reduction benefits.
On the morning of June 30, volunteers from the Yangtze River Vocational School welcomed guests from all parts of Wuhan in the pomegranate resort square. Volunteers prepared plant seeds, environmental protection tableware and low-carbon life manuals prepared by the organizing committee. People who paid for free visits to the plaza and visited the pomegranate red tour carefully read the low-carbon manual and were pleased to receive environmentally friendly tableware and plant seeds.
At 11 o'clock in the morning, the JMC light truck team arrived at the Pomegranate Red Primary School. The students were given a vivid and low-carbon environmental protection lesson. The children were encouraged to start from the small things around them and participate in low-carbon environmental protection activities. In addition, the Low Carbon China team also presented the plants with potted plants.
Subsequently, the launch ceremony of the event was held at the Pomegranate Resort Plaza. The organizing committee gave a banner to the representatives of car owners who participated in this “fuel-saving experience camp†event and presented low-carbon green backpacks to student representatives and car owners’ representatives. In order to encourage more volunteers to participate in the action of low-carbon environmental protection, the organizing committee specially awarded the volunteers a "low-carbon vanguard" plaque. At the end of the launching ceremony, the participating leaders, media reporter friends, schoolchildren's representatives, environmental protection volunteers, and on-site crowds signed their names on the banner of “JMC Light Truck Low Carbon China Tour†to express their strong commitment to the event. stand by.
The Grenadine Resort is located on the banks of the Han River embankment. It is surrounded by trees and green grass like blankets. In this very eco-friendly scenic spot, the “JMC Light Fuel Economy Contest†was held as scheduled on the afternoon of the 30th.
On the afternoon of this day, Wuhan, known as the "stove," was sultry and hot, and people were sweating in less than a minute outdoors. In order to avoid the participants and the referee's heat stroke, the referee group specified that the participating vehicles must open the air-conditioner in the third gear. For the sake of fairness, if you do not open or have a low gear, you will be disqualified. Eight light truck owners from all parts of Wuhan participated in the competition. The competition lasted nearly 20 kilometers and the fuel tank was used as an external fuel tank. In the end, Master Zhang Dengxiong won the championship with a score of 6.49L per hundred kilometers, creating a good record for the “JMC Light Fuel Savings Match†when air conditioning was turned on during the summer heat.
