Canon Patent Application: Grip based active cooling

[Canon Rumors]

Canon has released two patent applications going into detail about using a grip as an active cooling device for our overworked and overheating camera systems. I’ve long thought that Canon could do a lot more with grips than add a few batteries and call it a day – cooling certainly fits into the mold of

I wonder how much if any extra power would be available for the camera and how much would be for the cooling system itself.

Even though I fully understand that this patent is no joke it makes me feel like 1st of April.

I hope this fulfills some videographers dreams.

The Aliexpress commentary got you didn't it?

In all seriousness, there has been so many different ways that canon as attempted heat management, this actually looks like one of the more complete and elegant solutions

Basically, they have implemented this guy's advice after modifying his R5

Noooo! Gez, then you start to look, if other companies can, why Canon can't? Just do it smaller, in body, and lightweight.
After the 40s everything you wish is small and lightweight.

But***
Looking at the details of the photos, I think the next generation of cameras will come with passive cooling, and you can add a grip for active cooling.

small laptop styled fans are around 1-2 watts of power draw

i think their solution is a tad bit more portable than the water cooled one but yes, what he's saying is almost what they have implemented, except they are using air ducts.

Watch the second part of video, it ended up not being water cooled like in the title.
In fact, Kolari Vision's R5 cooling kit is basically just copying the original design he created and Canon is looking to do the same.
If the body is designed like what he said in the end, then the optional grip will be very effective.

Works for me.

That was a neat video.
The EL-1 Speedlite has internal active cooling. Perhaps this grip idea would work something similar.

No idea what makes you think of Aliexpress here. This just looks like any other laptop fan.

I hope he made a patent before he posted it on youtube

One would have to create vents in many areas to promote air flow thereby compromising weather sealing. A better approach would employ a jacketed/radiant and/or thermoelectric technique for cooling.

It looks like in the patent, the area the airflow is allowed to go through is sealed from the rest of the camera. So the heatsink itself can get wet, but the internals shouldn't.
Thermoelectric cooling wouldn't accomplish anything here. You still need a [larger] heatsink on the TEC, and they're terribly inefficient. Generally the only time you would look at using a TEC is if you need to keep very close to or under ambient.

 

[RikC]

Cool!

Apparently Canon hasn’t discovered heat pipe technology yet that has been used to transfer heat away from hot electronics for decades.

 

[Loswr]

Cool!

I see what you did there.

I'd appreciate a hand warming grip for wildlife shooting in winter: if your fingers get numb just start a longer sequence of 8 k video To be serious, this patent sounds like a smart solution. Even smarter would be new neuromorphic chip architectures that overcome the main problem of current Si technology: up to 90 % of the electric energy consumption is just transformed into heat, not information processing. Unfortunately, despite a lot of research since decades, such tech isn't going to hit the markets soon.

No, this is a Peltier cooler.
Pretty much the same as the R5 C, C70, S1H, FX3, Komodo, and many other weather-sealed cameras.
The fan is only for the heat sync.

Ah, I needed to look at the design more carefully. I thought it was a fan and heat sink which would require channels for air movement rather than employing TEC and the description is a bit confusing suggesting that there is a fan which blows air through channels in the camera body. So, is it a TEC, a TEC with a fan, a heat sink with a fan, or something else? Personally, I'm not a "fan" of an open system with channels which could accumulate, dirt, debris, moisture, etc.
