solution Tube piercing precision control In the process of tube piercing, it is necessary to ensure that the gap between the fin and the copper tube is uniform, which puts forward higher requirements

Process flow Fin processing: First, the aluminum sheet needs to be stamped into the desired fin shape using equipment such as a high-speed punch. The shape, size and spacing of the fins need to be pre

improves cooling efficiency Optimize design and material selection Material selection: Aluminum tube evaporator itself is made of aluminum, because it has a high thermal conductivity, which can effect

Material property Corrosion resistance 1060 aluminum tube has good corrosion resistance, and has good resistance to most acid, alkali and salt aqueous solutions, which makes it work stably in the evap

advantage 1.excellent thermal conductivity Aluminum has good thermal conductivity, and its thermal conductivity is high, which can quickly transfer heat from the inside of the evaporator to the extern

Production technology First, material selection According to the size and design requirements of the heat exchanger, the total length of the thermal conductive aluminum tube and the size of the fin ar

use Temperature range Aluminum tube evaporator is mainly used in the cold storage refrigeration system of 20 ° C to -45 ° C, and is the ideal evaporator for all kinds of food freezing and cold

Welding process Preheat: Use the welding gun or welding machine to preheat the welding part, increase the temperature of the welding area, and reduce the welding stress. Welding operation: Select the

Cause 1 Environmental factor Sun exposure: The surface coating of condenser fins exposed to sunlight for a long time may be eroded by ultraviolet rays, resulting in color fading or discoloration. Rain

design precautions Wall thickness requirements Under the requirements of pressure resistance, the wall thickness of the aluminum tube should be greater than 0.5mm to ensure its structural strength and
