Adhesive microlamination protocol for low-temperature microchannel arrays

Creator:

Paulraj, Prawin

Abstract:

A new adhesive bonding method is introduced for microlamination architectures, for producing low-temperature microchannel arrays in a wide variety of metals. Sheet metal embossing and chemical etching processes have been used to produce sealing bosses and flow features, resulting in approximately 50% fewer laminae over traditional methods. These lamina designs...

Metal Microchannel Lamination Using Surface Mount Adhesives for Low-Temperature Heat Exchangers

Creator:

Prawin, Paulraj and Paul, Brian K.

Abstract:

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...

Development of an adhesive-bonded counterflow microchannel heat exchanger

Creator:

Paulraj, Prawin, Paul, Brian K., and Peterson, Richard B.

Abstract:

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...
