Why is this not a thing?
Seems like it should be a thing.
Should I make it a thing on my build?
What sort of temps are people seeing on their things?
In general:
Biggest reason against is water getting in. Biggest reason for is keeping things cool, reducing chance of thermal runaway and such
Personally:
It’s hot where I love and Ive had the idea of adding a small fan to remove the hot air. I don’t really need to worry about remaining water right.
Are you experiencing high temps? Have you had thermal cut outs like @taz with his tight belts?
Have you any reason to do this other than science? If its science I am 100% behind full fan assisted esk8 enclosures with some mobile air con thrown in. Lets get the data centre nerds in here. We need help.
We are in the middle of a sub tropical storm and the nitrogen makes me weird
Ive been looking at gore vents. They will be going in to my mountainboard build

Ive also got rc fans on order 
Just cut some holes and use heatsinks. If you go out in the rain in se qld you can drown by looking up
Waterproof ventilation bro. Hoping it works. Also will likely be ordering heatsinks for the unities
I really like that idea. There was a guy on builders offering sheets of one way air travel membrane but he disappeared. I seriously haven’t had a problem with heat yet. Strange considering where I live and how I ride and the amount of vibration proofing I do. My enclosures are like camera cases. No air flow and no movement.
Im not expecting enough heat to warrant needing this stuff, just doing it anyway. For science.
Edit: the more efficiently I can run the components, the more life I can expect out of them… thats my theory anyway
I am not expecting high temps.
That’s more.than a theory. That’s exactly how electronics work. Industry standard for accelerated testing. We’ll measure failure.time at 120C and then do math to figure out when they’ll fail at 40C
Nice idea!
As I have started with non-enclosed vesc, and continue with air “forced”, I have never rich crazy temp, but I guess it’s why I continue building like this.
MTB style :
MadBox with air intake (instead of heatsink plate) :
Hybrid eSkate (from M@nu - esk8fr) :
Now we see heatsink everywhere, coming out of the enclosure to cool down.
But before, many were using a fan to extract hot air :
(back right its air forced)
But like you, I guess, I would like to see real report back (data) on the use with and without ^^
Hell ya! This is exactly what I was thinking. A waterproof mesh for air flow!
Unless your components are getting crazy hot I don’t see why
But a better idea that I’m doing in my small board is to make the whole enclosure bottom a aluminum plate, and everything mounted to it so it can also act as a heat sink, probably will have a cooling potential way bigger than the waterproof vents
Think like the heat sinks for vescs but spawning the whole bottom
That’s not a theory, heat kills electronic components. The cooler the better.
Large heatsinks means more weight. Only downside.
Water and debris ingress
Seems like it adds extra failure points over a solid-state design
Above 80C is “too hot” and above 90C things will start throttling. This is the FET temperature, not the inside air temperature.
So my build is gonna have heat sinks on the escs, fans in the enclosure and vents to circulate the air. Not sure if the BMS comes with a heatsink, but if it doesnt, i’ll make one
I dont ride lightly. Components are gonna need all the help they can get
Yeah, a bit, but 1/8” aluminum plate is not that much more when you are removing a large section of the enclosure
Has anyone taken cooling to the extreme with a custom waterblock and radiator? Yes it’s retarded and unnecessary but It would be interesting.
What’s the weight of an alu plate though? You just need a bit of thermal mass in there and it’s fine really.
I would argue that a few grams of heatsink is safer than making any unnecessary holes in your enclosure.
This also hugely depends on the board is for though! If you live in a place like Daren does on the sunshine coast and ride recreationally then an air scoop probably makes sense. If you’re like brian and blasting through snow and rain you likely wont want to poke holes.
i dont understand, how would a waterblock / radiator slow down an esk8? because of the weight?
