Samsung patents innovative system that uses audio devices to cool electronic devices

According to a report from AdroidHeadlines.com, Samsung has filed a new patent for an audio device, essentially a speaker, which will act as a fan does in laptops or personal computers and be a cooling channel for electronic devices.

The report described a heat pipe that directs heat to the speaker, which passes it on to the ambient through the sound reflection point.

 

“Fanless devices like smartphones, tablets, weaker laptops and such all use some method to disperse generated heat from its origin point, either to a designated output point, or to one or more contact points with the device's outer chassis,” the report added.

 

It continued, “A heat dissipation system like this could be implemented in tons of different types of devices, though there is one big limitation: size. In order to use one or more heat pipes to railroad excess heat to the speaker or microphone, a device has to be large enough to have heat pipes. That means this will likely be a no-go for wearables, headphones, and other electronics that tend to be smaller than a smartphone.”

 

The patent, which is detailed here, explained, “An electronic device with a heat radiation structure using an audio device is provided. The electronic device includes a first housing, a speaker module disposed on a surface of the first housing and configured to output sounds in a first direction, a sound reflection plate mounted above the surface of the first housing and having a first surface facing the speaker module, and a heat emission device disposed on a second surface of the sound reflection plate.

 

“The sound reflection plate may absorb heat generated from the heat emission device, and discharge the absorbed heat to the outside of the electronic device through a space between the surface of the first housing and the first surface of the sound reflection plate.”

 

A lightbulb is the device that is pictured in the patent and it also mentions a flashlight module.
