preface
In the blink of an eye to April, and Shenzhen is already the summer temperature, this time to play the game, obviously feel less energetic than the previous few months, an hour or two down, not only the sweaty screen oily, the picture frame rate also fluctuates with the temperature, five or six thousand iPhones run a chicken so stuck, this is urging the author to change the iPhone 13 ...
Fortunately, Bunkers recently launched a new magnetic heat dissipation back clip, compared to the old model to cancel the function of wireless charging, focus on heat dissipation, lighter weight is also more convenient to hold the operation, let's take a look at its specific use experience.
Product introduction
The packaging is full of e-sports wind, and the name of the ice wheel magnetic heat sink is quite loud.
The package contains a radiator, C2C charging cable and instruction manual.
The shape of the Bunkers magnetic radiator resembles the energy core of Iron Man, and the mecha style is quite in line with the preferences of the game crowd, with orange, black and silver stitching, and the shape is three-dimensional.
The same is true on the back, the black + orange silicone bonding surface, the product model is SR05, the input specification is actually 5V 2A (Max), and the product label has a small discrepancy.
Don't forget to tear off the protective film on the surface before use, which is somewhat similar to the CPU radiator, don't look at the thin layer, which will seriously affect the thermal conductivity efficiency.
The heatsink is powered by a USB-C interface, and the indicator light is lit after power-on, which is plug-and-play, which is very convenient. Dense heat dissipation fins can be seen on the sides, and fans are faintly visible. In order to ensure that the microphone work of the mobile phone is not affected, this radiator adopts a seven-bladed 4cm large-diameter fan, which is quiet and silent during the working process.
The diameter of the radiator is about 61.93mm.
The thickness is approximately 22.49mm.
The thickness is compared to the one-dollar coin.
The unit weight of the radiator is about 70.9g, which minimizes the problem of adsorbing the back of the phone.
The size held in the hand is as shown above.
The included C2C charging cable is a one-piece injection molded terminal housing.
The length of the wire is approximately 150cm.
Use with an iPhone
Since it is used with the iPhone, of course, it must be tested with the latest model.
The first is the iPhone 13 mini, it seems that the edge of the heatsink is still some distance away from the lens module, and the compatibility is no problem.
The iPhone 13 is even more problem-free.
iPhone 13 Pro is the hardest hit area of adaptation, and the distance is relatively close without a shell, but considering that users who generally pursue the ultimate heat dissipation experience will use the shell, it is not a problem.
The iPhone 13 Pro Max is even less of a problem.
Usage scenarios
Bunkers' magnetic heat sink is specially launched for the iPhone 12/13 series, which does not require any external force to be firmly adsorbed on the back of the phone, and the purpose of rapid cooling is achieved by the semiconductor heat sink of the magnetic suction surface.
The phone dissipates heat
The magnetic heat sink is equipped with a USB-C input interface, and the magnetic heat sink can be driven using the common USB-C cable.
The power consumption is about 7W.
With the magnetic radiator, you don't have to worry about the heating of the fuselage caused by the game for a long time, which will affect the experience of the game.
The connecting line goes down below, and there is no blocking phenomenon.
It should be noted here that the Bunkers magnetic heat sink is to suck in the air and then blow out by the built-in fan, so as to achieve the purpose of heat dissipation. Therefore, it should be noted that neither the air outlet nor the air inlet can block the dead. The air inlet of the Bunkers magnetic heat sink is located in the position of the circular plane, and the side opening is the air outlet.
Compared with the conventional heat dissipation back clip, there are many benefits to the magnetic heat dissipation back clip from the use experience. For example, in the picture above, the iPhone 12 mini cannot be completely clamped due to the small body of the fuselage, resulting in some heat dissipation back clips.
Or maybe this situation will block the phone lens.
Or maybe this is the case, the heat dissipation back clamp pressure on the mobile phone chip will have a better heat dissipation effect, many mobile phone chips will be placed on the mobile phone side of the position, if you want to achieve a better heat dissipation effect need to move the radiator as far up as possible, so that there will be a pressure to the power button situation.
Although the conventional heat dissipation back clip and the magnetic heat sink are both products that dissipate heat for mobile phones, the two are complementary. At present, most of the conventional heat dissipation back clips are launched by mobile phone manufacturers, and the adaptation of their own mobile phones naturally need not be said, but the degree of adaptation of other mobile phones cannot be guaranteed.
The advantage of the magnetic heat sink is that as long as there is magnetic suction, the iPhone 12/13 series can be used directly, the disadvantage is that it is used with a mobile phone that does not support magnetic absorption, so it is necessary to use the magnetic phone case.
Phone stand
In addition to acting as a radiator, Bunkers magnetic radiator can also be part-time as a mobile phone holder, summer with this small thing out, if you want to chase a drama can be directly with the magnetic radiator posture, simply not too cool.
Magnetic stickers
Unexpectedly, it can also be used as a magnetic chipper, usually if you do not use the radiator, the paste on the refrigerator can not only act as a magnetic patch, but also prevent the loss of the radiator, killing two birds with one stone.
Is the cooling effect obvious? No-load testing
First of all, let's take a look at the cooling effect of the magnetic heat sink when it is not loaded, put the radiator in a 25 ° C incubator to power up the work, and finally use the thermal imager to shoot the minimum temperature of the semiconductor heat sink at minus 10.1 ° C, and the temperature drop is obvious.
At this time, looking at the surface of the magnetic radiator, condensate has appeared. Here you need to prompt, no-load running is only used as a test, usually everyone should not run without load when using, to avoid damage to the radiator.
Running score test
Let's take a look at how the cooling effect is when used with a mobile phone. The following temperature test is based on a 25 ° C incubator, and the power of the mobile phone is more than 90%.
This is to leave the iPhone 13 in a 25°C incubator for a period of time, using a thermal imager to photograph the back of the phone at a maximum temperature of about 28.5°C.
Use the Wild Life Stress Test option in the 3D Mark test app to turn on the Unlimited mode test for 20 minutes, and again use the thermal imager to shoot the temperature on the back of the phone, the maximum temperature is about 40.1 °C, which is 11.6 °C higher than the initial temperature.
Tested with a heatsink
This test with Bunkers magnetic heat sink to take a look, before the test still put the iPhone 13 in the 25 ° C incubator for a period of time, using a thermal imager to shoot the back of the phone the maximum temperature of 22.8 ° C.
Use the Wild Life Stress Test option in the 3D Mark test APP to open the Unlimited mode test for 20 minutes, the test will be the heat dissipation back clip on the back of the phone, and finally the maximum temperature on the back of the phone was measured to be 28.5 °C, which was only 5.7 °C higher than the initial temperature.
Finally, the temperature changes in the entire test process are summarized into the table, and it can be seen that the temperature rise in the independent running of the mobile phone has increased by 11.6 °C, and the temperature has only increased by 5.7 °C with the heat sink under the same conditions, which is nearly 6 °C lower than the 11.6 °C when the mobile phone is independent. On the whole, the effect of the iPhone with the radiator when performing some high-intensity calculations such as games is still very obvious for the overall temperature control of the mobile phone.
Charging head net summary
Different from the traditional clamp-type semiconductor heat dissipation back clip, Bunkers magnetic heat sink is designed for magnetic mobile phones, the fixing method is more simple, a light touch is refreshing, no fixture mobile phone is more comfortable to hold; lightweight design, 70.9g of weight sucking on the back of the phone is not too heavy to outrageous; built-in silent fan, to avoid the heat dissipation process noise affect the game voice, calmer and quieter.
In the actual test, plug in the PD charger to use, the power consumption is about 7W, ten seconds can obviously feel the temperature drop of the silicone heat conductive surface, a long time to avoid the sharp weapon of frequency reduction.
In addition to the essence of heat dissipation, sucking behind the phone is still a good bracket, the conference room magnetic tape is not enough to do the work, a multi-purpose. So compared with the magnetic heat dissipation wireless charger launched by Bunkers before, which one do you prefer?
