    Microchannel heat exchanger

SOLUTION FOR COMPACT COOLING APPLICATIONS

Serpentine heat exchangers are the most compact and minimal in volume microchannel coils – without manifolds in their design. This arrangement enables serpentine coils for small, space-saving, and lightweight cooling applications. Being robust by design and manufactured from high-quality aluminum alloys, these heat exchangers assure long operating life even under extreme conditions.

COIL ARRANGEMENT

Serpentine heat exchanger typically consists of a single microchannel tube bent into a serpentine shape, fins, and connection pipes. All components are integrally brazed together in controlled atmosphere brazing (CAB) furnace:

  1. Microchannel tube bent into a serpentine shape
  2. Fin strips
  3. Inlet/outlet connections

Features and Advantages

For 20 to 3000 watts of heat rejection or cooling, these serpentine heat exchangers are the smallest and most versatile heat exchangers in the industry for refrigerant condensers, evaporators, and other applications. Based on the most advanced microchannel technology, each coil is designed to deliver maximum heat transfer, reliability, and easy packaging.

Our serpentine coils can be used with HFC-, HFO-based, and natural refrigerants as condensers in compressorized and pumped loop refrigerant systems and can be configured as evaporators for non-condensing cooling applications. Coil orientation, whether vertical, horizontal/flat, stationary, or in constant motion, has no effect on overall performance due to the single tube, serpentine design.

Serpentine coil models have ¼ inch aluminum/copper connections or optional ¼ inch copper connections, optional mounting methods, and a full range of sizes from 25mm to over 500mm, rated for 32 and 45 bar operating pressures or higher.

Applications

Serpentine heat exchangers are perfectly suitable for any compact cooling or heat rejection solution as a condenser or evaporator coils. Using serpentine microchannel heat exchangers, some thermodynamically efficient but flammable refrigerants can be extended to more applications.

  • Electronics cooling
