Tripath chip cooling

hi,
i am looking to build an amplifier based on the Hifimediy T2 (Hifimediy T2 2*100W TRIPATH TK2050 TC2000 T-amp Amplifier | eBay)

Having looked at many aluminium amplifier enclosures, none of them seem to have the option of air cooling with a fan. Instead they seem to be designed to conduct heat directly away from the chip. I have seen this design before, but they all use boards with the chip mounted on the underside of the pcb.

Is there any way i can cool this amp within a sealed enclosure?

thanks
 
most ClassD amplifier claim very high efficiency.
This results in low levels of heat dissipation from the amplifier circuitry.

At these low dissipation levels, fan cooling should not be necessary if they are telling "efficiency" truths.

Simply bolting the "chip" to the floor, or roof, or back panel, should keep the chip cool enough to operate to specification.
 
thanks, but the chip is mounted on the same side of the pcb as the rest of the components, meaning that i cannot mount it directly to the inside of the enclosure.
It does come with a heatsink, but will the heat build up within the case if there is no airflow?
 
Yes the heat will build up until the case warms sufficiently to dissipate the amplifier's heat.
That makes Ta quite high, but for a ClassD this could be relatively cool/warm.

Is there a way to use a thermally conducting spacer block that could be bolted to the case?
