HYMESH™ is an aluminium heat exchanger concept based on an all-extruded and fin-free design. Starting point is extruded linked tubular profiles. In a first step, the interlinking webs between tubes are partially removed. Afterwards, the resulting profile is extended in a lateral direction to separate the tubes.

HYMESH™ profiles can include:

• Extruded fin (HYMESH™-fin)
• Internally enhanced tube
• Externally enhance tube
• Customised hollow profile shape

Wind tunnel testing of prototype HYMESH™ heat exchanger assembly:
Test conditions used: 100°C oil and wind speeds of 4, 8 and 11 m/sec.

A conventional tube and fin brazed radiator, designed for automotive use, was used in the trials to provide comparative data to existing state-of-art heat exchangers.

Test results:

Achieved efficiencies of over 70% of state-of-art tube-fin heat exchanger for unrefined design. Improvement in performance is expected from future design studies.

Potential Applications and Identified potential market areas:

• Automotive
• Industrial Refrigeration / Cooling
• White Goods / Refrigeration
• HVAC&R

Other benefits:

Being of a unitary construction, HYMESH™ can be enhanced by surface finishing (e.g. anodizing) to impart corrosion resistance and for aesthetics
