Modern smartphones pack the power of a mini-computer into our pockets and are not limited to just one device for making calls. The load on these devices has increased due to heavy apps, fast processors and highly developed graphics. This kind of excessive load heats up even the best smartphones and ultimately affects the performance of the device. Modern users are also aware of the importance of a smartphone that will not burst under pressure. Smartphones generate a lot of heat, ranging from the title game of major mobile games to the dubious content. That’s where it is Liquid cooling technology Comes to the rescue. Let’s discuss how Liquid cooling The technology works on a smartphone and the various types of liquid cooling technology that phone manufacturers use.
How does liquid cooling work on a smartphone?
Liquid cooling on smartphones works on the principle of heat dissipation. Devices of this technology come with a pre-installed heat pipe to hold a cooling fluid. This pipe absorbs the excess heat generated from the processor and evaporates the liquid present in the pipe. Condensation of liquids helps in heat dissipation and gradually lowers the ambient temperature.
Vapor chamber cooling technology on smartphones
Commonly used liquids for cooling include – water, de-ionized water, glycol-water solution and fluorocarbon. However, most smartphones use a small amount of water, which is usually in the form of steam. As a result of this system the technology got a popular name – ‘steam chamber cooling’. The first two brands to adopt this technology were Nokia and Samsung, but now more than one of the latest smartphones on the market uses this cooling method.
What is Xiaomi’s Loop LiquidCool technology?
Xiaomi announced this technology in 2021 which is inspired by the space industry. The company claims that this technology provides much better cooling than conventional steam chamber cooling. Loop LiquidCool technology uses a “capillary effect” to draw liquid cooling agents into the heat source. The heat then evaporates the cooling agent and efficiently dissipates the heat towards a cooling area of the system. The steam then condenses in the cooling area and re-enters the heat source for its next cycle. This constant cycle helps keep the system cool. Xiaomi technology is expected to add a heat pipe system, an evaporator, a condenser, a refill chamber with gas and liquid pipes to make it work.
How is loop liquid cooling technology different from vapor chamber cooling technology?
Both technologies use the same technique to keep the devices cool, but unlike loop liquidcool technology, vapor chamber cooling lacks separate channels for liquids and gases. These individual channels limit the hot gas and cooling liquid from mixing in the cycle, which ultimately affects the functionality of the device. Xiaomi’s technology uses a Tesla valve to streamline the flow of the system. The valve only allows fluid to pass through when examining the gases from entering.
Other cooling technologies available
Smartphones use technologies other than liquid cooling to maintain the temperature of the device. The traditional ‘air cooling’ method that uses a fan to dissipate heat and cool the processor is also common. There is another method that helps maintain the temperature of the device. This method is called throttling because it limits the power of the smartphone before it hits the maximum.
