Test example: the same mobile phone sample is tested under the condition that the test environment temperature is 25 ℃, the test condition is that the temperature data is recorded when the mobile phone plays a video on line for 90 minutes, the electric quantity and volume parameters of the mobile phone are kept consistent in the test process, and the test data is as follows:
and (4) test conclusion: the method comprises the steps of utilizing the same machine, under the same test condition, the same test environment, the environment temperature is 25 ℃, running online video for 90 minutes to record data, performing step test, verifying a final test result that the temperature of a receiver, the temperature under a screen, the temperature in the screen and a fingerprint are in heat dissipation treatment, and performing heat dissipation treatment on the inner part of a mobile phone and a mobile phone screen, wherein the temperature of the receiver is effectively reduced by 4.7 ℃, the temperature in the screen is effectively reduced by 4.1 ℃, the temperature under the screen is effectively reduced by 3.7 ℃, the temperature of the fingerprint is effectively reduced by 3.4 ℃, the temperature of the back is effectively reduced by 3.2 ℃, the heat dissipation effect is obvious, the test data is the cooling effect when the temperature of the mobile phone is about 39 ℃, and if the mobile phone plays games for a long.
The significance of temperature reduction is that mobile phones are articles which are carried by everyone around the world, but every person is subjected to heat radiation caused by the heat of the mobile phones every day, as is well known, when the body temperature of one person reaches 38 ℃, the person feels uncomfortable, and when the body temperature of one person reaches 39 ℃ and 40 ℃, the person needs to go to a hospital to inject and take medicine. The mobile phone is an electronic product, and converts a fixed signal into a mobile signal through conversion of a received electric signal. The invention is a problem in long-term use, but the emerging of the new technology of the heat dissipation film of the mountain valley wind can bring the temperature of the mobile phone to be the same as that of the human body when the mobile phone is used by human, and the biggest contribution of the invention is that 80% of the time is below the temperature of the human body. The mobile phone synchronous with the human body temperature has no rotating feeling as the human body is in a geosynchronous orbit, which is the leading-edge technology of technological innovation.
The invention has the beneficial effects that: the nanometer tin antimony oxide dispersoid is used for dispersing polyethylene, polyvinyl chloride and polyethylene glycol terephthalate into a nanometer material, so that the material can be integrated with a toughened film through processing, the heat dissipation requirements of various electronic instruments, LED screens, air conditioners, refrigerator compressors and the like, such as spraying and baking and the production specificity are qualitatively changed, meanwhile, the raw material and time cost are greatly saved, the operation is simpler, the effect is better, and the efficiency is greatly improved; in addition, the heat dissipation film manufactured by the process has very obvious heat dissipation and cooling effects on compressors of various air conditioners and refrigerator refrigeration equipment, the compressor accounts for 88% of total energy consumption of the air conditioner, and the heat dissipation film can be reduced by about 15% after being pasted; the heat dissipation film is also suitable for LEDs, motors, air conditioners and refrigerator compressors. The heat dissipation film also has the function of ultraviolet protection.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
