A condenser with a diameter of 7mm
1.product Introduction
Using high-purity internally threaded copper tubes, the tube wall is uniform, the thermal conductivity is excellent, the pressure resistance is strong, and the small tube diameter structure is combined with the inner wall thread to enhance heat transfer, greatly improving the heat exchange efficiency between the refrigerant and the tube wall.
Adopting window opening corrugated aluminum fins to destroy the air boundary layer and increase ventilation and heat transfer efficiency; Optional hydrophilic film and electrophoretic anti-corrosion technology, with anti-corrosion, anti condensation, and easy to clean characteristics, suitable for complex working conditions such as outdoor, humid, and high salt spray.
Using mechanical tube expansion technology, the copper tube seamlessly adheres to the fins to prevent loosening and delamination; The overall sheet metal frame is sturdy and not deformed, the pipeline is evenly distributed, the heat dissipation is stable, and high-pressure faults caused by bias current and uneven heat dissipation are eliminated

3.Product feature and application
Pipe diameter specification: standard outer diameter 7mm, matched with thin-walled high tooth internally threaded copper pipe, wall thickness 0.22-0.35mm, spiral tooth reinforced inner wall heat transfer surface
Adaptation structure: Equipped with window/corrugated aluminum fins, compact tube arrangement (single/double row universal), triangular hole spacing arrangement, suitable for household refrigerators, commercial freezers, small refrigeration units, industrial cooling equipment
Fluid characteristics: The flow volume inside the tube is much smaller than that of traditional 9.52mm (3/8 inch) large tubes, the refrigerant flow rate is increased, and the heat transfer boundary layer is thinner; Compared to 5mm ultra-thin tubes, the pressure loss, corrosion resistance, and processing stability have been greatly optimized and compromised, making it the universal diameter for balancing performance, cost, and durability in refrigeration equipment
Processing characteristics: The bent pipe is not prone to wrinkling and has a low probability of expansion cracking. The welding and expansion molding processes are mature, and the mass production yield is high. It is suitable for automated production lines
This product is suitable for vertical fresh-keeping cabinets, cake display cabinets, and beverage refrigerators
Supermarket air curtain cabinet, small quick freezing freezer, kitchen countertop freezer, milk tea equipment, ice maker, ice cream machine condenser

5.Deliver,shipping and serving
1, Delivery
Production and delivery
Automated electrophoresis assembly line for mass production, with regular specifications available in stock; Customized sizes and integrated electrophoretic models with shells are delivered on time according to the order cycle. After production is completed, full inspection of air pressure leak detection and paint appearance is carried out to prevent defective products such as welding leaks and paint peeling from being shipped out.
Shipment Inspection
Each product is checked for model, size, and electrophoretic paint integrity, with a specification list attached. Foreign trade orders can be accompanied by packing lists and certificates of conformity to meet export customs declaration requirements.
Delivery method
Support factory self pickup, whole vehicle delivery, less than truckload logistics, and full container shipment. We can cooperate with customer designated freight forwarders to arrange container loading.
2, Transportation
protective packaging
The outer layer of the product is covered with protective film, and corner protectors are added. For large and multiple items, hard cardboard boxes/wooden frames are used for reinforcement; Electrophoretic paint surface is scratch resistant, anti-collision, and avoids transportation wear, exposure, and rusting.
