TL Type Chiller
Product Overview
The TL-type surface cooler is a copper tube through aluminum foil type cooler, utilizing mechanical expansion and arched wave-shaped double-flanged aluminum auxiliary plate structure. The mechanical expansion ensures tight contact between the copper tube and the auxiliary plate, while the arched wave shape promotes fluid turbulence, disrupts the boundary layer, and enhances the heat transfer coefficient. The structural design, combined with reasonable water passage, pipe spacing, and fin spacing, results in excellent heat transfer performance, low air resistance, compact structure, and light weight. It is widely applicable in air conditioning, cooling, dehumidification, and heating projects, making it a suitable matching product for air handling units and air processors. Additionally, it can be connected to ductwork for use as a cooling or heating unit independently.
Copper tube welding is performed using low-temperature rapid brazing, ensuring pressure resistance over 1.2 MPa.
The cooler features a variety of fin spacing (2.5-3.6mm), and currently offers a full range of available types to meet the needs of different operating conditions and various combinations.
From thermodynamic theory, it is known that for water-air heat exchangers, the large thermal resistance is on the air side. To increase the heat transfer coefficient, it is necessary to reduce the thermal resistance on the air side. An effective method is to utilize the boundary layer theory, increase the turbulent state of the air, thereby enhancing the heat dissipation coefficient on the air side. For this purpose, four auxiliary fin shapes have been designed:
●V-type aid ●V-shape + slits ●Sine wave ●Sine wave + bridge
The four types of auxiliary sheets mentioned above can meet the various process requirements of different users.
