One of the complications involved in designing an

intercooler is setting the size and dimensions of the unit as

well as the spacing of the passages in the core. This nearly

always involves a series of compromises. Space is generally

very limited under the cowl, and its shape is rarely ideal.


Having sorted out a location and determined the available

space, the next step is to determine the size and spacing of

the passages in the core. Typically the core is symmetrical,

with the same spacing on both sides. This is the least

xpensive way to do it. When the simple arrangement doesn't

yield a big enough temperature drop and low enough inlet

temperatures, then the engineer may try increasing fin count to

help increase heat transfer. In some cores the fin spacing on

both sides may be different, inevitably boosting the cost of

the unit.
