Evaporator aluminum tube
The aluminum tube of the evaporator can be made of 1050, 160, 1070, 1070 A, 1100 industrial pure aluminum, or 3003 alloy by extrusion, drawing, etc. It can also be produced by continuous extruder, and the production process is mature. The size of 1050, 160, 1070, 1070 A, 1100 aluminum round tube is mostly 8×1mm in diameter, which can be extruded by a common extruder. It can be produced by a continuous extruder. The material is in O or H112 temper, and the dimensional deviation is divided into ordinary grade and high precision grade.
Condenser aluminum flat tube
The fracture surface of the aluminum flat tube for condenser is similar to a harmonica, often referred to as a harmonica tube, and is used as a fluid conduit in a heat exchanger in which a cooling medium passes inside the tube. The number of holes in the tube is generally 5-25 holes, the wall thickness is 0.6-0.8mm, and it can be thinner and the height is 5-6mm. The harmonica aluminum tube pipe is not only thin, but also has many holes and is more difficult to squeeze. Moreover, it is required that the channels are relatively closed, the weld bead structure is free from defects, and it is not broken during cold deformation, and can withstand a pressure of ≥8 N/mm2.
