So, any ideas how to improve this design? Bigger heatsinks? Additional lamination on the boards?

Moar boards. For easier replacement of single failed chips. So you don't have to accept beeing 2 of 6 in a defunct state because 4 still left running. There are 12 inside, the material costs for placing them on 6 Hash boards instead of merely 2 are negligible.

The older designs had been the better ones. Except installation layouts, sometimes (depicted) (not mine)

There is a modern design of old technologie available, these casings are best industry practice.

Overall containing a dozen huge FPGA (not ASIC!) chips, 6 on a single Hash board.
Just from my (outdated) experience running ZTEX boards, those who closely assembled a Cairnsmore1 device:

They did not last for long, old devices usually featured 3 of 4 chips remaining and 1 dead chip which was not replaceable. Placing 6 on each Hash board requires perfect cooling conditions.
