A heat pipe is a sealed pipe that contains a liquid that changes from liquid to gas to move the heat from one location to another and this design is not doing this at all. I answered in post above. You did not catch it while you write your reply. 14 minutes ago, mike_bike_kite said: I thought I explained fairly clearly why I thought your design wouldn't be effective. I suggest you answer those points before trying to pull rank. You answered clearly with this: 49 minutes ago, ESBU said: You don't see heat pipes on desktop PC's because the space isn't limited and they produce more heat than the pipe can deal with. My friend, I think now its time to stop it. When I receive (hope it will be soon) my Sherman, I can make review if there is a space to develop my idea of "passive" cooling EUC circuit board. edit: for Admin - maybe start new topic f.e. "Cooling mods for Veteran Sherman" and move our discussion about it there ? Edited June 14, 2020 by ESBU Quote Link to comment Share on other sites More sharing options...
onizukagto Posted June 14, 2020 Share Posted June 14, 2020 (edited) I like all these talk about "pipes" and "passive" cooling. as a design engineer, it'll be cool if euc has done down of cooling system. just like a sealed pipe that contains a liquid that could be circulated to hot areas and then to a cooling area like a radiator of a sort which can be placed in front of moving air. if only pc's and motorbikes had something like that, then maybe this EUC could have it too..... just my 2 pence contribution.

This wheel isn’t for someone who needs to put it in a car. It’s meant for someone riding their uni to the final destination. 6 Quote Link to comment Share on other sites More sharing options...

who_the Posted June 14, 2020 Share Posted June 14, 2020 Do we know the battery configuration of the Sherman? Is it 24s10p? EWheels says 240 cells in their FAQ. Quote Link to comment Share on other sites More sharing options...

houseofjob Posted June 15, 2020 Share Posted June 15, 2020 Any of the EE guys have any insight on why Veteran is using HOOYI / HY MOSFETs (not sure which model) over the industry fav TO-247? https://www.ewheels.com/product/new-veteran-sherman-18-100v-3200wh-battery-2500w-motor-1000-deposit/ Quote Link to comment Share on other sites More sharing options...

HY (Hy-line?) is the mosfet brand/manufacturer. It's the same ones Gotway uses. TO-247 is a mosfet package (= the dimensions of the cooling casing for each mosfet, the black plastic block you see). This is a generic descriptor. They are doing the same thing Gotway is doing. HY mosfets in a TO-247 (presumably) package. Probably exactly the same components. They're ex-GW and Chinese, after all. No worries needed here edit: The MSX uses HY5012 mosfets (I assume that is the same as 5012W), and I believe GW stayed with them from then on (for their newer wheels). So Veteran has the same mosfet setup as Gotway. Everything's good. Edited June 15, 2020 by meepmeepmayer 2 Quote Link to comment Share on other sites More sharing options...

Remember the inexplicable 84V Nikola with TO-220? It's always the super simple, dumb, avoidable stuff with Gotway, hopefully not Veteran.

houseofjob Posted June 15, 2020 Share Posted June 15, 2020 Also, anyone notice Colonel Sherman has both Calibration AND Pedal Angle settings, when most wheels it's the same thing(?)

Agreed, but I’m trying to see if I’m understanding correctly that this is what this in fact is. Also, all new EUC company starts have been a wealth of promise and hope in their initial phases, but after that honeymoon phase is really when they show their strengths and weaknesses. 2 Quote Link to comment Share on other sites More sharing options...
