Analysis of Xiaomi’s ice-cooled back clip.
On February 13th at 2 pm, Xiaomi held a new product launch conference online, and the Q & A after the conference was presented in the form of a video conference. There is no doubt that the protagonist of this conference is the Xiaomi 10 series. According to Lei Jun, the Xiaomi Mi 10 series is the dream of Xiaomi’s 10-year success, because this product uses almost all the latest technology of the current high-end smartphones.
In addition to the Xiaomi 10 series, Xiaomi has also launched a magical accessory called the ice-cooled cooling back clip, priced at 129 yuan, developed by the Black Shark department. Once this accessory was released, it caused a lot of discussion among netizens. What is it? Why does Xiaomi have an ice-cooled cooling back clip? What practical value does it have?
Xiaomi ice-cooled cooling back clip = “Install an air conditioner for your phone”?
The students who watched the new product launch of Xiaomi must remember that Lei always compared Xiaomi’s ice-cooled cooling back clip with the desktop CPU cooling fan. The test conditions were divided into three steps: 1. Two Xiaomi 10 baking machines at room temperature 30 minutes; 2. Cool the cooling back clip with Xiaomi and the computer radiator for 1 minute at the same time; 3. Measure the temperature drop of the center of the fuselage after cooling.
The final comparison result is staggering. Xiaomi’s ice-cooled cooling back clip cools the phone by 10 degrees for one minute, while the computer’s radiator only cools the phone by 6 degrees for one minute. In this way, Xiaomi’s ice-cooled cooling back clip has won with a temperature difference of 4 degrees. Don’t be too happy now, friends who know computers must know the hidden secrets.
Before publishing this secret, let’s first understand the heat dissipation principle of Xiaomi’s ice-cooled cooling back clip. It actually uses a semiconductor cooling sheet. The working principle of the semiconductor cooling sheet is very simple. When you give him When the power is on, due to the Peltier effect, the cooling sheet will transfer the heat from the A side to the B side. At this time, the A side will become cold, and the B side will become hot. There is also internal consumption in the semiconductor cooling sheet, and some current It will be converted into heat and also emitted from the B side, so Xiaomi added a small fan to dissipate the heat on the B side.
The working principle of the CPU air-cooled radiator is that the CPU radiator base directly contacts the CPU.The heat is conducted to the heat sink base, and then the base is transferred to the heat sink fins through the heat conducting device, and the heat on the heat sink fins is blown away by the fan.
The Xiaomi launch conference was the CoolerMaster T610 tower air-cooled radiator. The tower heat dissipation is like a tower, very large, with one-way air blowing, fins and fans are large, and the heat dissipation performance is great. It is best, but it can only dissipate heat to the CPU. The heat dissipation of the motherboard and memory must be given to the fan on the chassis.
The reason why Xiaomi’s ice-cooled back clip is stronger than the CPU heat sink is because the CPU heat sink needs to be in direct contact with the components and use the specific heat capacity of the metal to take away the heat. Xiaomi installed the heat sink directly on the back of the phone, which does not match the working principle of the heat sink. Secondly, at a temperature of more than 30 degrees, the CPU heat sink basically does not work much. Generally, when the computer CPU is idle, the temperature is within 50 °, when it is busy, it is within 65 °, and at full speed, it is within 75 °. At this time, the full function of the CPU radiator will be exerted.
In simple terms, the cooling effect of Xiaomi’s ice-cooled radiator cannot be compared with the computer’s CPU radiator. It is really comparable, and the results can be imagined. So, if you want to buy a Xiaomi ice-cooled cooling back clip to cool the computer CPU, let’s wake up.
Why does Xiaomi make a mobile phone radiator?
After understanding the working principle of Xiaomi’s ice-cooled cooling back clip, let’s analyze why Xiaomi launched a mobile phone radiator. Friends who like to play mobile games, does this accessory resolve your anxiety?
It is well known that, in addition to affecting the grip of the mobile phone, the temperature of the phone will also cause the CPU to drop frequency due to the high temperature. Later, the phone experienced a series of problems such as freezes, unstable signals, slow charging speeds, and short battery life. For example, the iPhone X and XS are very hot, and the frequency reduction is also very obvious. If you are playing a game, you can feel that the screen will freeze.
The reasons for the heat generation of mobile phones are mainly related to the process technology and the architecture of the CPU. The former gradually controls the heat as the technology is updated, and the latter increases with the frequency.
In other words, the stronger the processor, the more heat and power it will inevitably bring. Therefore, you need a radiator to help your phone cool down, which may be one of the reasons Xiaomi launches a mobile phone radiator.
Can another reason be understood to imply that the Snapdragon 865 has a large amount of heat, and the graphene or copper tube built in the mobile phone alone cannot dissipate the Snapdragon 865? I don’t know if you still remember the ROG Gaming Phone 2, which is equipped with Qualcomm Snapdragon 855 Plus processor, built-in liquid-cooled heat dissipation architecture, 3D Vapor Chamber vacuum cavity soaking plate, and cooperates with copper and aluminum thermal conductive plates. Under such a powerful cooling configuration, ROG still introduced Cooler Fan 2.
Game phones not only have high requirements for configuration, but also are very picky about heat dissipation, but ROG still chooses to launch mobile phone radiators to make the temperature of mobile phones more stable. It is not difficult to see that Xiaomi is also a reason to make a radiator.
What’s the value of Xiaomi’s Ice Sealed Radiator?
As for the last question, for manufacturers, Xiaomi’s ice-cooled cooling fan has undoubtedly become a new profit point, which is helpful for the promotion of the Xiaomi 10 series. With the purchase of mobile phones and accessories, users can get better Product experience. In addition, it also solves the problem that some users feel that the mobile phone is hot. Xiaomi has listened to the user’s suggestions on the side, so it can create a good brand image.
From the perspective of the user, there is another purchase option. Compared with other competing products, Xiaomi’s ice-cooled cooling back clip is still very cost-effective. Although there are many dozens of radiators on the Internet, but after-sales The service is not necessarily as good as Xiaomi, and the brand is at least guaranteed. Secondly, when you are playing a game, using it together with this cooling back clip can make the stability of the phone better, and the CPU will not be underclocked due to overheating. The most intuitive feeling is that the game screen is stuttered. The situation has become less, no matter how you hold the phone, you will not feel hot.
Of course, not only playing games, some mobile phones will also have severe heat when shooting 4K videos. At this time, it is Xiaomi’s turn to turn on the ice-cooled backrest.
Summary
Although Xiaomi’s ice-cooled cooling back clip is a good product, it can improve the consumer experience, but it is a bit too much to compare it with the computer’s CPU air-cooled radiator at the press conference. After all, the two The cooling principle is different.
Plus there is no comparability, the real thing to compare is andMobile phones without radiators, or compared with other competing products, what are the characteristics of their radiators, such as better heat dissipation, which can control the temperature of the phone?
People who do n’t know computer knowledge will make them mistakenly think that a mobile phone radiator is better than a computer radiator. In fact, it is just the opposite. If the temperature of the mobile phone is above 60 degrees, compare the two. The results are obvious. However, the temperature of the mobile phone will not be higher than 50 degrees, and 40 degrees is basically the highest. If the temperature rises further, it may shut down.
Anyway, Xiaomi’s ice-cooled cooling back clip is still very practical, and consumers are willing to spend more money in exchange for a better product experience. The price of 129 yuan is not expensive. If you feel that your mobile phone is not good at cooling, you might as well buy it for a try. We have also done a period of evaluation on the cooling of mobile phones before cooling.
