Description

M268654 IV. Creation Instructions (1) [Technical field to which the new type belongs] Fantastic creation: Is there a cooling fan that is independent of the power supply? Yun Han ^ t continues to be driven by the delay device after the computer is turned off ;: The fan runs for a period of time and continues to release heat from the power supply f to achieve the effect of stopping heat accumulation and temperature rise, forcing [prior technology] Order. = Technological progress, integrated circuits and various electronic advances, which will increase the amount of heat generated by the calculation and processing of f in the early bit time;: idJ, relative and drive its internal devices (such as: optical, disk drives) That is): In addition, the power supply must provide higher power output. In particular, the processing speed of various devices in the computer has been relatively increased, so it must be installed with more wind power. 1 The power source is still powered by the power supply), this == fan power supply must maintain high-power output mode Li Ui step-down rectified electronic components (such as commutator, electric commutator, transformer! Its pre -... effects, however, when the power is turned off (Sof t Of f): the two fans are stopped at the same time when the power supply is cut off, and the wind is also stopped due to the integrated circuit and electronic components and commutators, Transformer = —The normal operating temperature is already quite high. When the fan suddenly stops, the heat will gradually accumulate because it is not affected by wind, which makes its temperature rise suddenly, and the temperature often exceeds the normal operating temperature for a long period of time. Long time m Page 5 M268654 IV. Creation instructions (2) During the period of 'the so-called temperature-recovery phenomenon', it will often cause damage to the integrated circuit or the aforementioned electronic components or affect the service life of the system. In view of the lack of previous disclosure, the industry has improved it. Among them, as shown in the first figure, it is the patent case No. 8 722 1 1 97. The delayed shutdown of the cooling fan is installed in a power supply. The power supply system includes a main power system 30, a standing power system 31, a switch control circuit 32, and a cooling fan 33. The main power system 30 can be turned on or off by being electrically connected to the switch control circuit 32. When the main power supply system 30 is turned off, the standby power supply system 31 continues to operate to supply the power required for the operation of the switch control circuit 32, and the delayed shutdown device 34 is a rotation of the standby power supply system 3 * 1. Power is provided to the cooling fan 33, so that the cooling fan "continuously rotates to reduce the ambient temperature inside the power supply; however, the front-delay and delayed-shutdown device, although it can be used, still has the following shortcomings: : First, the standby power system of the power supply 31 general output + 5VSb 'It is mainly when the main power system 30 is off, it supplies the backup power required for the computer switch control circuit to operate, and the standby power system shuts down the computer The only available power supply is as follows. In the computer system as mentioned above, due to the calculation and processing = speeding up, not only the heating of electronic components inside the power supply increases, but also CPUs such as motherboards and graphics cards (VGA cards). (Or other high-heating electronic components, the heat generated by them is not too high after the power is turned off. 'All the aforementioned electronic components or the central processing unit will generate heat and temperature rise effects due to the fan stop, making their temperature High in order to solve the temperature rise effect of CPUs such as motherboards after shutdown. 'Most CPUs in computer systems are equipped with a fan to delay shutdown.

Creation instructions (3) (eg, Patent No. 87102139), use and continue operation for a period of time to smoothly discharge the gate to achieve effective heat dissipation, prevent temperature rise and long system fall; set, ;; closed device Ye Wei-can only be used by the standby power supply system for extended power supply, but taking into account the relatively important computer system VSB central processing needs heat dissipation and its service life and stable production f principles, the power supply: the processor, the central processor set the wind : Shi Eryuan: Mo / knife or so, and the large fan of the power supply fan Xiao Nu ^ 4 X 4 (according to-the size of the large fan is the smallest to reach i2Xl2 cm or more) to provide cooling, because: 丄 + 5 The backup power supply of VSB is powered by the central processing unit. This means that at the same time, the central device, the power supply, and the power supply: start :: need: even the prevention of heat dissipation and temperature rise effects cannot be achieved in advance.

The separate controller is the mains power supply and the counter's counter force output. After the system is closed, it is really prevented from accumulating from the power supply for the system. The configuration and power of the central processing heat fan are not prepared to supply heat. This cooling wind current I) Performance. Power output, the input end of the device is connected to a cooling fan, the power of the control heating fan is based on the main power supply, which is forced to dissipate heat when the computer is shut down, and the power supply system uses a conventional power supply board or graphics card to delay the device to the original computer. The power converter of the heat fan reduces the rectification to drive 'cause the rate P = voltage VX to achieve rapid heat dissipation, the power supply to the cooling fan to close the time of the cooling fan, so the need for the electronic heat fan of the Ministry' is improved. It is easy to say that 'will not affect the supply of scattered electricity through the power conversion (such as + 1 2 V) results' (operation at high speed, set when the computer is turned off and the main power is activated by its feedback signal, and The converter's step-down rectification reaches the set time, and according to the above characteristics, it can be known that the controller is actuated by the controller—the section can continue to affect the heat and temperature rise in the power supply. + 5VSB standby power, and the original heat dissipation and protection of the guide should be distributed independently of the standby power; In addition, the delay device uses + 5VSB, but it is a city fan, so it can be used. The high-pressure fan has better power output effect, and the cooling fan can also be a cooling fan delay device of the secondary purpose of this creation. It is separately set independently of the power supply supply state. When Xia is independent of the power supply , As long as Lei Chu silk 袼 ^ = with the property or power specifications for automatic delay off M% 埶 π turn, °° and eight input terminals in parallel, you can improve the function of "closed government", fan, not The I ρ ^ reactor needs to be changed or re-arranged, so not only the original power supply is used, but the objects used in the application are diverse, and
