In Mastering the Art of French Cooking, Julia Child is all about the fraisage. She describes the motion as a way “to ensure an even blending of fat and flour.” So why, exactly, is this good thing? Doesn’t it go against all American-style-pie-dough rules? It does. But it also works—producing a different but just as indispensable pastry.

Microchannel heat exchangers are becoming quite popular as an alternative to bulky fin-and-tube heat exchangers. For a desired capacity, a microchannel heat exchanger is smaller in size than a fin-and-tube heat exchanger, resulting
with a given microchannel tube design and a fixed multi-louvered fin geometry, the model was exercised to simulate the thermal-hydraulic performance of various two-, three-, and four-pass circuit configurations over a range of coil
Local heat transfer downstream a single pin fin in a microchannel was experimentally studied. • The interaction between the flow structure and the local heat transfer was revealed.
The MicroChannel heat exchanger (MCHE) is ideal for use in residential and commercial air conditioning systems in simple all-aluminum lightweight design.

Microchannel’s low profile coils are easy to clean, and its aluminum construction provides resistance to galvanic corrosion. • Coastal applications: ... better heat transfer than fin-and-tube models. Title: Microchannel Heat Exchangers Author: Daikin Applied Subject:
Sectional oblique fins are employed, in contrast to continuous fins in order to modulate the flow in microchannel heat sinks. The breakage of a continuous fin into oblique sections leads to the reinitialization of the thermal boundary layer at the leading edge of each oblique fin, effectively reducing the boundary layer thickness.
