This paper reports the feasibility of using surface mount adhesives to produce low temperature microchannel arrays in a wide variety of metals. Sheet metal embossing and chemical etching processes have been used to produce sealing bosses that eliminate channel laminae, resulting in approximately 50% material savings over traditional methods. An...
A low-temperature liquid-to-vapor counterflow microchannel heat exchanger has been redesigned and fabricated using a scalable, low-cost adhesive bonding process. Adhesive erosion concerns are mitigated with the use of sealing bosses. Performance has been tested using water and compressed air as test fluids. Results show greater effectiveness and higher heat transfer...
