Copper extruded fin tube for heaters by Murphy

-
Copper extruded finned tube has excellent heat conduction characteristics. The fins increase the heat exchange area, improve the heat conduction performance, increase the heat exchange rate, and save energy and material. Murphy copper fin tubes are widely used in various types of heaters, heat exchangers, refrigeration equipment, chemical engineering, power station auxiliary machinery, ship auxiliary machinery cooling machine.

Brass is an alloy of copper and zinc. If it is only composed of copper and zinc, it is called ordinary brass. Brass is often used to make valves, water pipes, connecting pipes of air conditioners and radiators. Brass tubes are generally used to make heating coil tubes for condensers and coolers and tubes for general purposes. Brass 68 and 70 for condensers and 62 for general purpose cold drawn tubes from 3 to 100 cm OD. Its length is 1-6 meters. Tubes for condensing cooler and other heat exchange equipment shall be subject to water pressure test with pressure up to 50 kg / cm2, and the test time shall not be less than 10 seconds. Compared with the shell and tube heat exchanger, the brass tube has the following advantages: 1. High heat transfer coefficient, which is due to high velocity, turbulence and complete countercurrent; 1. The weight of equipment required for unit heat transfer is small; 1. The compensation of temperature deformation is good. What are the charact...

Fin heat sink is mainly used for cooling and heat dissipation of power electronic equipment, which is widely used in rail transit, wind power generation and other fields. At present, there are three main assembly processes of heat sink base plate and fin: extrusion riveting, low temperature welding and gluing. In the process of extruding and riveting insert, the base plate will be deformed after being stressed, which will seriously affect the subsequent processing. At this time, oil pressure will be used to ensure the flatness of the base plate. If the base plate deforms seriously, some fins will be loose after oil pressure. For a long time, extruding and riveting deformation is a difficult problem affecting the quality of fin heat sink products. The laser welded composite fin tube, Murphy experts takes the fin heat sink of a certain type locomotive as the cutting point. Aiming at the phenomenon of thin base plate design, serious deformation and uneven fin spaci...

Finned tube as a heat exchange element exhibits excellent performance indicators

Finned tube is a kind of heat exchange element, which is often used in high temperature and flue gas space. In daily life, such as boilers, finned tubes need to be used for heat exchange execution. In such a harsh environment During daily operations, the finned tube itself is required to have corrosion resistance and stability. The finned tube is a typical heat exchange element, in order to improve the heat exchange efficiency, usually by adding fins on the surface of the heat exchange tube to increase the outer surface area of ​​the heat exchange tube, so as to improve the heat exchange For the purpose of efficiency, such a heat exchange tube. Finned tubes work under high-temperature flue gas conditions for a long time. For example, finned tubes for boiler heat exchangers are used in harsh environments, high temperature and high pressure and in corrosive atmosphere, which requires finned tubes to have high performance indicators. For example, excellent corrosion resistance. Many tim...
