I am not sure how you have coded the heat exchanges to work but they seem a bit clunky...It seems to just transfer a ton of heat to the reactor then next pulse its like"oh shit the reactor has tons of heat!" and then it takes it all back...then its like "i have a ton of heat" and the cycle continues.
Also the reactor seems to send heat back to all the exchanges equally. Instead of sending more to exchanges that have idle vents around it. So maybe setting a flag on each vent as to weather it should be receiving or sending.
One other thing that i like to do is place 2-3 exchanges and surround them with coolant cells as an emergency backup...but the exchange system doesnt seem to be smart enough to send all the excess heat to those cells when i am peaking out my heat.
These are just my thoughts and constructive criticism...Hopefully you can look into some of these suggestions.
Thanks
Just a suggestion but shrink the numbers. so instead of seeing 501,892,234,234K shrink it to something like 501 Trillion. Its a hell of a lot easier to look at.

You lose precision in that for example upgrade could cost "0 Trillion" quite often. Of course if you guys prefer it that way I don't mind changing it!
