Description of the Invention: [Technical Field] [0001] The present invention relates to a temperature monitoring device, and more particularly to a temperature monitoring device in a personal computer case. [Prior Art·] [0002] With the rapid development of computer technology, users are increasingly demanding the simplicity and convenience of computer technology applications. The user needs to monitor the current working state of the computer, whether it is in a safe working state, and whether the system temperature is too high. Electronic components such as the central processing unit η (CPU) on the computer motherboard are becoming faster and faster, which generates a large amount of thermal energy in the computer system, resulting in a much higher temperature inside the computer. However, when the computer is working at an excessively high temperature for a long time and the user cannot detect that the working life of the computer motherboard and the electronic components mounted thereon is shortened or even damaged, the current personal computer chassis usually has multiple fans. The heating element heats up, which increases the cost. At the same time, each fan can only dissipate heat for one heating element separately, and the heat dissipation angle can not be adjusted, so the heat dissipation efficiency is not high. i. u [Summary of the Invention] [0003] In view of the above, it is necessary to provide a temperature monitoring device that is low in cost and highly efficient in heat dissipation.

[0005] 相比 Compared with the prior art, the temperature monitoring device detects the temperature condition of the heat source by the module, and switches the conduction channel of the control module to change the flow through the comparison module. The direction of the current of the fan drive module is such that the air deflector connected to the fan drive module is driven to a corresponding heat source for heat dissipation. [0006] Referring to FIG. 1, a preferred embodiment of a temperature monitoring device of the present invention includes a detection module 100, a comparison module 200, a control module 3, and a fan.

The anode of the inverter wheel of the comparator A1 is electrically connected to the anode of the diode D3, and is electrically connected to the cathode of the diode D1 via the resistor R1. The comparison terminal _ input terminal is connected to the adjustment terminal of the variable resistor RP2. The inverting input terminal of the comparator A2 is electrically connected to the anode of the diode D3, and is electrically connected to the anode of the diode D3 via the resistor R2. The in-phase input terminal of the comparison nA1 is electrically connected to the non-inverting input terminal of the comparator A2 via capacitors ^ and C2. The control module 3 includes a transistor 1'1, a 2, a her & a relay, a second relay, resistors R3, R4, and capacitors C3, C4. The first relay of the fan includes a coil K11 and a switch K12. The second relay has a first loop Κ 21 and a switch Κ 22. Each switch includes a first end, a second end, and a third end. The bases of the transistors T1 and T2 are electrically connected to the wheel terminals of the comparators Α1 and Α2, respectively, via the electric_099109454 form number Α0101, page 6 / page 16 0992016787-0 201133169 Ο, R4.

In a preferred embodiment of the invention, the transistor ΤΙ, T2 is an NPN type transistor. [0010] 〇 Referring to FIG. 3', the motor 401 is disposed on one of the rotating shafts 2 of the computer case. A rotating cam extends from each end of each rotating shaft 2, a transmission gear 10 is fixed on the top of each of the rotating shafts, and a wind deflector 30 is fixed on each rotating shaft 2''. When the motor 401 rotates, the drive gear 10 at both ends of the rotating shaft 2 驱动 can be driven on a transmission lane 40, and the rotation of the motor 4〇1 drives the transmission gears at both ends of the other rotating shafts 20 It also slides relative to the drive track 4 〇. At this time, the air guiding piece 30 on the corresponding rotating shaft 20 also rotates with the relative sliding of the transmission gear 1〇 and the transmission rail 40, and the opening direction between the air guiding plates 3〇 is changed, so that the cooling fan in the computer case is cooled. The direction of the wind flow can be changed under the action of the wind deflector 30, so that heat is dissipated according to the temperature condition in the computer case. In the initial state, each switch is electrically connected between the corresponding second end and the third end. When the temperature in the computer case is constant, it can be changed by the variable resistor 099109454 Form No. A0101 Page 7 / Total 16 Page 0992016787-0 [0011] 201133169 The adjustment end of RP1, RP2 changes its resistance, thus making the comparator A1 The non-inverting input of A2 is higher than the potential of its inverting input. At this time, the output terminals of the comparators A1 and A2 respectively output a high potential so that the transistors ΤΙ and T2 are both turned on, and the coils K11 and K21 are energized so that each switch electrically connects the first end and the third end. The motor 401 is in an inoperative state. [0012] In operation, the +12V DC voltage produces a reference voltage of +6V at the inverting input of the comparators A1, A2. If the temperature of the upper part of the computer case is higher than the temperature of the lower part, the resistance values of the thermistors RT1 and RT3 become smaller. At this time, the potential of the non-inverting input terminal of the comparator A1 rises, and the output terminal still outputs a high potential to turn on the transistor T1, and the coil K11 is energized to make the switch K12 electrically connect the first end and the third end. The potential of the non-inverting input of the comparator A2 is lowered, and the output of the comparator is low, so that the transistor T2 is turned off, and the coil K21 is not operated, so that the switch K22 still electrically connects the second end and the third end. The current flows in the counterclockwise direction through the motor 401 to rotate the air deflector 30 on the rotating shaft 20 in the first direction, and the opening between the air guiding fins 30 faces the upper portion of the computer case. The cooling fan in the computer case can blow the airflow to the heating element in the upper part of the computer case under the action of the air guiding piece 30 to dissipate heat. [0013] If the temperature of the upper portion of the computer case is lower than the temperature of the lower portion, the resistance values of the thermistors RT2 and RT4 become smaller. At this time, the non-inverting input terminal of the comparator A1 is lowered in potential, and the output terminal outputs a low potential so that the transistor T1 is turned off, and the coil K11 is not operated, so that the switch K1 2 still electrically connects the second end and the third end. The potential of the non-inverting input terminal of the comparator A2 rises, and the output terminal still outputs a high potential, so that the transistor T2 is turned on, and the coil K21 is energized to make the switch K22 electrically connect the first end and the third end. The current flows in a clockwise direction through the motor 099109454 Form No. A0101 Page 8 / Total 16 pages 0992016787-0 201133169 401, thereby driving the wind deflector 3_ on the rotating shaft 2〇 to rotate in the opposite direction to the first direction, the wind guiding The opening between the sheets 30 faces the lower portion of the computer case. The cooling fan in the computer case can blow the airflow to the heating element in the lower part of the computer case under the action of the wind deflector 3〇 to dissipate heat. [0015] [0020] [0020] [0020] 099109454 The creation temperature monitoring device detects the temperature condition of the heat source by the detecting module 100, and The comparison module 200 switches the conduction channel of the control module 300 to change the direction of the current flowing through the fan driving module 4, thereby driving the wind deflector 3 〇〇 connected to the fan driving module 4 The corresponding heat source is used to dissipate heat. The temperature monitoring device of the invention can dissipate heat for a plurality of heat sources in the computer case by using a single fan, thereby reducing manufacturing cost and improving heat dissipation efficiency.
