Canon Patent: Externally Connected Camera Cooling Device

Well, that’s a somewhat different Canon patent application for once.

Canon patent application 2022-21539 (Japan) discusses methods and technology to connect an external camera cooling device.

PROBLEM TO BE SOLVED: To provide an externally connected electronic device for cooling that can be connected to an image pickup device.

The present invention relates to an electronic device, and more particularly to an electronic device that can be externally connected to an image pickup device and dissipate heat to the image pickup device. However, in the technique described in Patent Document 1, by arranging the ventilation duct inside the image pickup device, a large space for installing the blower duct is required, which may hinder the miniaturization of the image pickup device. The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide an externally connected electronic device that can be connected to an image pickup apparatus.
In order to solve the above problems, the present invention comprises an interface unit including a connection unit that can be attached to the external device by connecting to an interface terminal provided in the external device, a heat transfer unit, a heat dissipation unit, and the like . The electronic device is characterized in that the heat transfer section and the heat dissipation section are connected to the interface section, and the interface section is in the opposite direction to the external device when the interface section is connected to the external device. offer.

If we got it right, it is an external cooling device that can be attached to the camera and connected to an USB port. We think the device has a Peltier element and a fan. It can be attached when needed, so it can be seen as a portable camera cooling device.

The camera depicted in the drawings appears to be a mirrorless camera, and pretty much looks like an EOS M camera. Canon planing to release an overheating EOS M model? :-)
