Mobile phone heat dissipation accessories are support devices that help cool down mobile terminal devices. As smartphone performance continues to improve, the problem of overheating under high load is becoming increasingly prominent, seriously affecting the user experience, operating performance, and even hardware lifespan. With the continuous development of technology, people have increasingly higher requirements for the heat dissipation efficiency, portability, and compatibility of mobile phone heat dissipation accessories.

[0003] Existing mobile phone cooling accessories have certain drawbacks in use. First, traditional air-cooled mobile phone cooling cases rely solely on fans for heat dissipation, which has limited cooling efficiency and cannot meet the high-load cooling requirements of mobile phones. Second, conventional semiconductor cooling accessories mostly use an external and continuously activated cooling chip control method. Due to limited heat dissipation space, heat can easily accumulate on the heating surface, resulting in rapid attenuation of cooling effect and significant power consumption. In addition, some cooling accessories have low structural integration, are inconvenient to disassemble and assemble, and have poor fit with the mobile phone, which has certain adverse effects on actual use. To address these issues, we propose a liquid-cooled mobile phone case with integrated semiconductor cooling. Summary of the Invention

[0032] Working principle: The integrated semiconductor cooling liquid-cooled phone case of this invention uses the phone case body as a supporting carrier, integrating a heat dissipation structure with an air-cooling module, liquid-cooling components, and a semiconductor cooling chip as the core, as well as a control and power supply structure with a PCB circuit board as the core. During operation, it consists of three stages: initialization self-test, AI-level temperature control, and intelligent protection and sleep mode. Initialization self-test: After the heat sink is powered on, the processor module controls each module to perform self-test initialization. If an interrupt signal is detected, it is determined to be a temperature interruption, low battery, Hall effect valid, voltage control interruption, touch valid, button interruption, etc. In the case of non-temperature interruption, the indicator light module alarms and controls the device to enter low power sleep mode. Only when temperature interruption occurs will the AI ​​temperature control program be entered.

[0033] AI-based graded temperature control: The processor module uses a temperature sensor module to monitor the temperature of the phone and the heat dissipation module in real time. First, it determines whether the temperature is higher than the first temperature threshold. If it is, AI-PID-1 is activated to control the fan to run at a low speed. If the temperature continues to rise to the second temperature threshold, AI-PID-2 is activated to control the liquid cooling to run at a low speed, while the fan speed is increased to medium speed. If the temperature rises to the third temperature threshold, AI-PID-3 is activated to control the liquid cooling to run at medium speed, while the fan speed is increased to high speed. If the temperature reaches the fourth high threshold, the liquid cooling to high speed and the TEC module to cool are activated. At the same time, the processor module monitors the temperature of the cooling and heating surfaces of the TEC module in real time and uses an intermittent temperature control method. When the temperature of the cooling surface stops decreasing and the temperature of the heating surface is about to rise, the TEC module is turned off and restarted after the temperatures of the cooling and heating surfaces are equalized to avoid heat buildup.

[0034] Intelligent protection and sleep mode: The low battery monitoring module detects the battery level in real time. When low battery is detected, the processor module controls the heat dissipation modules to stop working and enters a low-power sleep mode. The Hall switch module and touch sensing module also trigger low-power sleep mode when they detect that the device is not in contact with the phone or there is no operation. The charging contacts charge the battery through the charging adapter module, battery charging module and battery protection module to ensure the stability and safety of power supply.

[0035] It should be noted that, in this document, relational terms such as first and second (number one, number two), etc., are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
