Description of the invention: [Technical field of invention] Regarding a fan system and its temperature-sensing protection device, a fan module having a temperature-sensing element and a temperature-sensing protection device thereof [Prior Art] Generally speaking The electronic system has an electronic system that can be maintained on the "normal ^ (four) line ' to break the proper temperature, the temperature of the wood, so that the electronic system: is lifting. The fan system itself also has specific usage rules. For example, the fan system is operating at the temperature of the erat temperature. 5 - wind = read \ \" A conventional fan system 1 mainly includes 12 turns and a starter module 12. The startup module is configured to start the fan module U for heat dissipation. However, when the temperature of the wind is too high or too low, the fan system will be caused: 曰:. In response to such problems, conventional techniques typically employ an analogy control of the cymbal 13 to sense the fan system! Operating temperature, = When the operating temperature is too high or too low, the fan system i is automatically stopped to achieve the protection effect. / Is the analog control chip 13 expensive, so the conventional fan system 1 overall production cost is too high. In addition, the analog control chip 13 cannot achieve the soft-start effect. Therefore, the present invention provides a fan system and its temperature protection protection 288801 to improve the above problems. SUMMARY OF THE INVENTION The object of the present invention is to provide a fan system, a ware/dish, and a sampan county, by stopping the fan when the operating temperature of the temperature sensing element is too low. The system operates to achieve the protection of = 4 for the above purposes - according to the invention - a fan system package 5 feathers & group, - start module a temperature sensing element and - control mode ', towel. The startup module is electrically connected to the fan module, and is activated by the 扇n. The temperature sensing element is based on the ambient temperature, and the production 2 corresponds to the H test number; the control group receives and controls according to the sensing U. The starting module, when the ambient temperature is higher than the first temperature or lower than the first temperature, controlling the starting module to close the fan module for the above purpose, according to a temperature sensing device of the present invention The fan module is matched, and the temperature sensing device comprises a starting mold, a ▲ sensing element and a control module. The starting module is electrically connected to the fan module and used to activate the fan module; the temperature sensing component generates a corresponding sensing signal according to an ambient temperature; the control module receives and is based on The sensing signal is used to control the starting mode=, and when the ambient temperature is high, a temperature is lower than a second temperature, the starting module is controlled to close the fan module. According to the above description, according to the fan system of the present invention and the temperature sense of 1288801, the operating temperature of the "age" / wind / / sense element is too high or too low I, ^; ^ nt " ^ "11&quot 〇^ f ^ ^ ^ ^ Sense component 四 (4) 1; 温 t 温 温 温 温 温 其 其 其 其 其 其 其 其 其 其 其 其 其 其 其 其 其 其 其 温 温 温 温 温 温 温 温 温 温 温 温 温 温 温 温 温 温 温 温 温 温 温[Embodiment] Hereinafter, referring to the phase M type, the fan system of the embodiment of the present invention and the temperature sensing device thereof will be described. Please refer to FIG. 2, which is a preferred embodiment of the present invention. 2 can be applied to an electronic system: not shown) internally for use as a heat sink. The fan system 2 includes a fan module 2, a starter module, a control module 23, and a temperature sensing element 24. The fan module has a fan, and a plurality of fans are respectively disposed in the fan module 21 according to the heat dissipation requirement, so as to enhance the heat dissipation effect, wherein the startup module 22 is electrically connected to the fan module 21, and To activate the fan module 21. The temperature sensing element is According to an ambient temperature, to generate a corresponding-sensing signal%, the temperature sensing element 24 can be a thermistor, and the temperature sense (4) (4) is a negative temperature coefficient thermistor. The temperature of the internal temperature of the electronic system can be determined according to the ambient temperature to generate the corresponding sensing signal Vt (which can be a voltage value). Due to the characteristics of the negative (five) coefficient thermistor itself, When the electronic system internal temperature = .1288801, the fan system 2 acts as a square-τ- as follows: 内部 the internal temperature of the electronic system (4) - between the temperature and the second temperature (normal operating temperature of the temperature sensing element 24 The generated sensing signal % is the same; the younger brother > Vrefl ' and lower than the second reference signal>: 2: therefore the first, the closing element Q1 and the second switching element Q2 are turned off The switching element Q4 is turned on, and the port cp幵' starts charging until the voltage value of the capacitor c reaches the starting voltage of the third switch ndu n _ m Q3, then the third:: element q3 Turn on to start the fan module 21 for heat dissipation. 1: The fan system 2 can increase the current of the cleaning device 21 ^ ^ ^ ^ 21 21 21 21 21 21 , , , , , , , , r r r r 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇 风扇It achieves the effect of soft start. = When the internal temperature of the electronic system is higher than the first temperature, the test signal vt is lower than the first reference signal %, so the first: 〇疋: Ql is turned on 'the first The four-switching element Q4 and the third switching element are closed, and the fan module 21 is turned off for the same purpose of protection. 'When the internal temperature of the electronic system is lower than the second temperature two: the sensing The signal Vt is higher than the second reference signal Vref2, because the switch '2 is turned on' the fourth switching element and the second off element Q3_, so that the fan module 21 is turned off to achieve the same effect. It can be seen from the above that the fan m senses whether the internal temperature is higher than the upper limit operating temperature or lower than the 'temperature' and is higher than the upper limit operating temperature or lower than the lower limit of 12.1288801 to prevent the fan system. When the temperature is '__', the fan module 21 system 2 is damaged. • Sheming also revealed a kind of temperature protection device, which is compatible with a fan module.
