Brass tube basic instruction

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...

  What is G type fin tube Finned tube  is a kind of heat exchange element. In order to improve the heat exchange efficiency, fins are usually added to the surface of the heat exchange tube to increase the external surface area (or internal surface area) of the heat exchange tube to achieve the purpose of improving the heat exchange efficiency. Such a heat exchange tube. The outer surface of the fin tube is covered with small fins. The role of these fins is to act as a transfer process and filter. Heat transfer is usually from the inside to the outside and then in the reverse direction.  G type fin tube, also known as  embedded finned tube , where g means slotted. It is formed by screwing fin strips made of copper or aluminum into machined grooves and backfilling to secure the lock. Fill the base tube material. Compared with other finned tubes,  G type fin tubes are firmer. Therefore, it is widely used in places where high-temperature heat transfer is requir...

Improvement of fin image technology based on anti deformation principle

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...
