Finned tubing has a compact construction and is simple and cost-effective to install. The number of joints is reduced in comparison to extruded aluminium tubing, allowing for faster and more cost-effective installation while also reducing the risk of water leaking at the connection. After installation, finned tubes need little to no maintenance; in fact, they are almost maintenance-free. Because the finned tube makes complete contact with the aluminum pipe, it has a higher heat dissipation area than a bare tube, and the interior is smoother. As a result, the internal water flow resistance is lower than with a bare tube.
Because of the combination of fins and pipes, it has a long service life and strong mechanical strength. tensile strength exceeds 200Mpa in this case. Heat transfer performance that is stable. This metal surface exhibits minimal temperature variations, which helps to minimize high temperature corrosion and over-heating damage to the metal surface. Heat exchange between air and air, air and liquid, liquid and liquid, and other fluids is possible with this device. When it comes to heat exchangers, this kind of aluminum composite tube is most often employed as a header pipe.
Heat exchangers for automobile radiators, intercoolers, and oil coolers, as well as radiators for the engine cooling system, heaters, and air conditioning systems, are all made of high-frequency welded aluminum flat tube. Likewise, an aluminum alloy seamless collection tube is used (base material is 3003 or 6063). The brazing material is 4045 or 4343, which accounts for 5 percent to 10 percent of the overall thickness of the sheet metal work. A characteristic of the heat exchanger is its homogeneity, high bursting pressure, and long-term stability of its heat exchange quality.
Aluminum that has been extruded vs aluminum that has been drawn
Aluminium is a material that may be used in a variety of applications. It is possible to shape aluminum in a variety of various ways. Aluminized steel is the primary raw material for aluminum manufacturing, followed by drawn aluminum and extruded aluminum.
The primary distinction between extruded aluminum and drawn aluminum is the manner in which the aluminum is formed in the molding process.
Aluminized extrusion is produced by heating aluminum and pushing it through a mold under high pressure. The final look of the product is determined by the form of the mold. For instance, a "I" mold may be used to create aluminum I-beams. After the product has been moulded, it is allowed to cool before being stretched to remove any deformation that may have occurred during the cooling process. With time, the aluminum hardens and becomes more durable. Although the hardening process may be completed at ambient temperature, most producers choose to employ heating chambers to expedite the process since it is time-consuming.
Aluminium multi-channel tube is also referred to as aluminum multi-port tube in certain circles. It is intended for use by the automotive air-conditioning sector. In addition to the ordinary aluminium pipe, the aluminium multi-channel tube also includes a sharp corner pipe, an internal tooth pipe, a zinc spraying pipe, a conjoined pipe, an intercooler flat pipe, and other unique pipes. The vehicle air conditioner, public air conditioner, heat exchanger, condenser, and evaporator are some of the most common applications. The large or small multi-channel tubes are available in a variety of diameters and alloys, guaranteeing that they have the optimum characteristics for the application in question.
Heat exchanger tubes made of high-precision drawn aluminium are widely used in many applications, including heat exchangers. Our products include aluminum round tube, internal thread tube, seamless collector tube, old drawn aluminum tube, seamless drawn aluminum tube, capillary tube, peanut tube, and other types of tubes. Terminal goods such as residential and commercial air conditioning evaporator and condenser, automotive air conditioning evaporator, radiator condenser and water tank are made mostly of this material.
CHAL is a supplier of heat exchanger finned tubes in China.
Aluminum condenser header pipe, also known as aluminum condenser manifolds, is a critical component of HVAC systems and is available in a variety of sizes. The main use is to ensure that coolant in pipe circuits in air coolers, dry coolers, evaporators, and condensers is distributed evenly in order to prevent the formation of temperature layers in the passing air stream. The header is made consisting of an enlarged pipe that guarantees that the speed and pressure are so minimal that they have no impact on the intake resistance of the various circuits. During the cooling process, fluorine is compressed by the compressor to create high-temperature and high-pressure liquefied gas, which is then condensed by the condenser to form a low-temperature and high-pressure liquid, which then enters the collection tube.
