Hot Stuff !

got to be joking.. an onboard radiator? A good idea but abit too far for me!
I thought much more were taking the..... with their cooling systems (fridge heatsink and now wire heatsink.... ) but this just takes the biscuit.. the theory is there but if someones car is getting so hot they need somthing as extreme as this then somthing isnt right.

[jimmy]

haha, thats ace - bit spensive though I have to say. but cool

If that actualy wrapped around 3/4 of the motor can, and they provided you with thermal paste too, then I might think, yes, it would work, but for a small plate, it is completely down the wrong end of the motor.

As far as cooling goes (TC related as we speak), the 'get it as cold as possible before racing' gets my vote, fans just seem a waste of time unless you get plenty of cold air right into the comm, as it is, most of the cooling air does nowt.

just thinking, with the like of the T2 and Corally, the whole rear end acts as a heatsink, so sticking something inbetween also seems a little, erm, odd, think they best stick to CPU cooling.

Hi,
Seems to have been developed by Richard Weatherley & co.
I have been experimenting with in car cooling, liquid cooling seems average as it can only go down the ambient air temperature, compared to Peltier cooling which can below the ambient. There are fors and against regarding the different in car cooling solutions.
I have though, gone back to the ''the 'get it as cold as possible before racing' '' philophosy and created a Motor freezer. This seesm to work increadably well. Pics attached. PM for more details.

Regards

Ross

Where do you get a peltier like that ? how much ? seems to work rather well - I had a go on the muchmore one when I was at the Euros and it got the motors cold but certainly not freezing (but it was a hot day)

[DCM]

You can buy peltiers on ebay, but the problem being, the colder the one side, the hotter the other, plus you GOT to keep the hot side cooled. I would definately go for a peltier if it wasn't the rip-off cost of the muchmore one.

Steve thing about the sarnie for a second

surely if the face to face contact is good enough then the 3 bits become a thermal one - all cooled by the bit in the middle in this case.

Do you think we need paste ? we dont use it with a normal motor plate and that certainly gets warm ?

I spoke to Richard this morning and he has data that proves it works.

We will soon find out for sure.Not sure if it's a big deal in offroad but I know my Pred can run hot with a wilder motor in it. If I was racing Tc in 27t or 19t at nationals and it does work as advertised then I would HAVE to buy one.

[jimmy]

my pred was melting the solder every run at oswestry this year, not because it was a pred but because it was hot. My B4 even melted.
Its a cool innovation, they just need to make one for brushless ESC's now too! hehe

[PaulRotheram]

Your B4 melted going the speed of light jimmy! bloody fast that was

they do. .

[jimmy]

Oh ! I guess they must then! I guessed that just meant it was a different shape or something, but if its a heatsink for the actual ESC then thats cool (!) shame they dont show a pic of it tho.

[burgie]

Jimmy - i think we are at cross purposes - the TCS for brushless systems is a beefed up version of the TCS for brushed motors - it's not something for the heatsink on the ESC.

so in answer to your question, they do. and they don't! :eek:

[jimmy]

Confusion reigns supreme!

I managed to burn my fingers on my LRP sphere ESC, so bring on the ESC version!

[DCM]

I agree, but heat dissipation is done as a 'radiated heat', as coming off from a rather hard run with the tourer, even my chassis gets warm, but it isn't acting as a heatsink, it is just picking up the heat from the motor radiating heat outwards, thats why I am not a great fan of, erm, fans.

The issue with mounting it on the end bell is that there isn't much metal there, you will get a small reduction, but not nearly as much as a liquid jacket round the can, just think about your Car engine, if you just put a cooling jacket on the front or side or bottom of the engine, it is far less effective than a cooling jacket that a modern engine has.

Thermal Paste, tell you what, go pop the air cooler off your CPU, clean the thermal paste away, put the cooler back on, then run a diagnostic with the comp running, then put fresh paste on and check again, you will find a significant difference.

I am not deniying that this is a clever design, just don't think the implementation is done correctly.

I am not sure if I am allowed to tell you if you are right Jimmy. But you are obviously going to get something extra for the extra money

[bert digler]

i build pumps for a living that will last about 10 seconds the radiator idea for starters how much waters in there or cooling fluid an egg cup full that aint gonna take long to boil is it and then the hoses blow off spraying coolin spaff all over the electrics cool

[BenG]

what if.... A genius person made a 'jacket' that fit round a motor, that you stick in the freezer, and it freezes, then you sticfk it over your motor as you race, and it keeps temp down LOL

[DCM]

Do you have a freezer with you when u race?

[B3buggy]

Hi,
I have been contemplating a motor 'Jacket' as the motor freezer is more than capable of cooling it down. One thing is the air restrictions by blocking the vents, this could be go round though by leaving holes. I would have thought copper is the best bet as a material. I have a bit lying around, might knock one up. Think it may have to be two piece,or somehow clamp on.
Any ideas?
