Problems solved by technology

[0004] The problem faced by this method is: when the fan itself fails, the warning information on the device, such as the indicator light or the sound alarm, may not be fed back to the operator in time, because the operator cannot observe the fan installed in the system. equipment
[0006] The problem faced by this method is that the temperature field where the thermally deformed parts are located is very different from the temperature field where the electronic components are located, so the collected information often cannot accurately reflect the working time of the high power consumption devices on the module. temperature, the change of the state of the ventilation hole derived from the thermal deformation part through its own deformation is difficult to achieve the design effect predetermined by the designer
[0008] The problem that adopts this kind of method to face is: existing automatic control technology is often according to an input parameter, such as the temperature of main chip, corresponding adjustment is aimed at the rotating speed of the cooling fan of this chip and the angle of air channel plate (controlling with micro-motor assembly )
The existing thermal design ideas that are compatible with different environments are difficult to solve the high and low temperature problems faced by equipment in specific harsh environments, especially when some parameters of the two environments are completely opposite, such as the low temperature in the airborne environment. Air pressure and high temperature and humidity in the shipboard environment
[0010] For example, in a low-pressure environment, the efficiency of forced convection using air as the heat transfer medium is very low. Even if the fan speed is adjusted to the highest level, it is difficult to effectively dissipate heat from local high-temperature locations.
At this time, it is necessary to make major adjustments to the heat dissipation scheme, including comprehensive adjustments to the fan speed and the path of the air flow. For such a complicated situation, it is difficult to achieve a good heat dissipation effect with a simple automatic adjustment method.
In order to avoid this situation, the heat dissipation method mainly based on conduction and radiation will often lead to a significant increase in cost and equipment weight.
[0011] In addition, in the prior art, it is also proposed to install different temperature adjustment devices for different scenarios where electronic equipment may be used. implement complex problems
[0012] It can be seen from the above description that the starting point of the existing technology is to aim at a certain specific environment, or to be fully compatible with several specific environments, sometimes at the cost of sacrificing the efficiency of the temperature adjustment device, after realizing the reliability of the electronic equipment , it is often difficult to take into account the miniaturization, light weight and low cost of equipment
[0013] It can be seen that if you need to be compatible with the two usage environments, you need to pay high costs, even at the expense of the reliability of electronic equipment
