Therm-Jett™

Conventional coolingTherm-Jett™ cooling

• Conventional cooling for an ATCA or PICMG chassis has lower cooling capacity because of the air flow being parallel wit h the PCB.

• Therm-Jett™ increases the cooling capacity since the flow is ne ar-normal to the PCB – much higher heat transfer coeff icient.

• Therm-Jett™ has better cooling than complicated liquid cooling techniques with significantly lower cost and increa sed reliability.

Therm-Jett™ Operational Principle

Delivering high capacity cooling (jet impingement) by introducing a perforated plenum in between PCBs or on top of a single PCB.

Perforated plenum made of sheet-metal –mounted either on the PCB or as integral part of the chassis

Therm-Jett™

Therm-Jett™ Technology can be applied to 1U and larger chassis as well

Air is pulled into the 1U system through the standard front panel

Then air is driven out of the fans into the Therm-Jett™ baffle and

the over the perforated plate. Back pressure forces the air down through the perforated plate onto

the hot board underneath

Motherboad is under the Therm-Jett™ plate

• The data from graph shows a significant decrease in ∆ ∆ ∆ ∆T (TComponent – Tambient = 8 to 20oC) for

impingement compared to conventional flow.

Experimental data for 15 locations on a simulated board for conventional and impingement cooling

• By optimizing the shape of the impingement duct, we expect to double the cooling capacity

of an ATCA/PICMG chassis compared to conventional cooling method.
