I. Equipment Application
This equipment is specifically designed for the tube expansion process of heat exchanger coils and is a core piece of specialized equipment in the heat exchanger production process. Classified as a versatile Horizontal Tube Expander Machine, it also integrates the mobility perks of a Mobile Expander and the convenience of a Portable Heat Exchanger Expander for diversified workshop scenarios. Its core function is to achieve diameter expansion at the ends or in specific sections of the copper tubes in the heat exchanger coils through precise tube expansion technology, ensuring a tight assembly of the coil with the tube sheet, end caps, and other components, thereby improving the sealing performance and heat exchange efficiency of the heat exchanger. This equipment is widely applicable to the coil processing scenarios of various heat exchanger products, including air conditioning heat exchangers, industrial chiller heat exchangers, and HVAC heat exchangers, providing key process guarantees for the stable operation and efficient heat exchange of heat exchangers.
II. Core Technical Parameters
- Compatible Copper Tube Diameter: Φ7-Φ25mm. This parameter covers the commonly used copper tube specifications for mainstream heat exchanger coils. Whether it's the small-diameter copper tubes for small household air conditioning heat exchangers or the large-diameter copper tubes for large industrial heat exchangers, precise adaptation can be achieved without frequent changes to core tooling, effectively improving the equipment's versatility and production flexibility. This universal sizing fits all variants of this Horizontal Tube Expander Machine and portable mobile models alike.
- Expansion Length: Customizable according to the buyer's actual production needs. The equipment, through its adjustable mechanical structure and intelligent control system, can precisely control the tube expansion length, enabling expansion from short-distance end tubes to long-section segmented tubes. It fully matches the personalized processing requirements of different models and structures of heat exchanger coils, ensuring the adaptability and precision of the processing technology. As a flexible Mobile Expander, it accommodates variable length demands across on-site and fixed production setups.
- Expansion Speed: 5-11 meters/minute. The equipment adopts a high-efficiency power transmission system and optimized expansion mechanism design, achieving high-speed and stable expansion operations. This speed range can be steplessly adjusted according to the specifications, material, and expansion precision requirements of the copper tubes being processed. While ensuring expansion quality (such as avoiding copper tube deformation and cracking), it maximizes production efficiency and meets the production needs of different capacity scales. This stable speed performance is consistent across the Portable Heat Exchanger Expander and full-sized horizontal configurations.
III. Equipment Model Design
To adapt to the capacity needs and production layouts of different users, three models are available: single-tube, double-tube, and four-tube. Users can flexibly choose according to their production scale, coil batch size, and workshop space conditions, with each model retaining the core merits of the Horizontal Tube Expander Machine while offering mobile or portable configurations as needed:
- Single-tube model: Adopts a single-station, single-channel design, with a compact structure, small footprint, and simple and easy-to-understand operation. This lightweight version doubles as a highly maneuverable Mobile Expander for small workshops and trial production.
- Dual-tube model: Utilizing a dual-station parallel design, this model can simultaneously expand two copper tubes. Compared to the single-tube model, it nearly doubles the production capacity while balancing space requirements and efficiency. Suitable for medium-batch heat exchanger coil manufacturers, it is the preferred model for balancing capacity and site costs, blending the stability of a Horizontal Expander with the flexibility of a Portable Heat Exchanger Expander.
- Four-tube model: Featuring a four-station synchronous operation design and equipped with a highly efficient automated feeding and positioning system, this model enables simultaneous and precise expansion of four tubes. Its significant capacity advantage meets the needs of large-scale, standardized heat exchanger coil batch production, effectively reducing unit product processing costs and enhancing the company's market competitiveness. This heavy-duty variant is a high-output Horizontal Tube Expander Machine optimized for mass production lines.
