[Prior Art] Press, the back panel of a conventional computer mainframe is equipped with a rear fan for discharging heat generated by the work inside the computer main body. Recently, since the power consumption of the CPU has been greatly increased, it is often necessary to add a front fan to the front panel of the computer mainframe. In any case, the rear fan or the front fan will always produce noise along with the operation, and these noises are directly transmitted to the user because there is no isolation measure, which not only hinders the peace, affects the work mood, but also makes the user's hearing in the long run. Damaged. [Invention] The main object of the present invention is to provide a housing having a heat dissipation gate that can automatically adjust the size of the opening for heat dissipation according to the heat dissipation requirement to achieve a good heat dissipation effect. Specifically, the housing having the heat dissipation gate of the present invention has a structure including a housing having at least one opening, and two opposite sides of the opening - each having two brackets, and being disposed between the brackets There is a heat-dissipating gate, and the heat-dissipating gate comprises a plurality of blades, a transmission device and a motor, 5 1285079. Each of the blade systems has a rotating shaft, and the rotating shaft rotatably spans the opening On the two brackets, the transmission is for synchronously rotating the blades, and the motor has a power output shaft for driving the transmission. In this way, the open space of the opening can be controlled by the rotation of the blade of the heat-dissipating gate, so as to meet different heat dissipation requirements and achieve a good heat dissipation effect. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the first preferred embodiment of the present invention, a casing (1) for use in a personal computer main body is disclosed. The casing (1) has a casing (2). ) and a heat-dissipating gate (3). The front plate of the casing (2) has an opening (2 〇), and each side of the opening (20) is formed with a bracket (21). The heat-dissipating gate (3) further includes a plurality of blades (3〇), a transmission device (31), and a motor (32) having a power output_axis (3 2 1). Wherein: each of the blades (30) has a rotating shaft (300), and the two shafts (2) are rotatably traversed on opposite sides of the opening (20) by the rotating shaft (300) (2) 1). The transmission (31) is a belt transmission mechanism comprising an active pulley (3 1 0), a plurality of driven pulleys (31), and a plurality of belts (3 1 2). The driving pulley (3 1 〇 ) is fixed to the motor (3 2 ) for power transmission 6 1285079 .. output shaft (3 2 1 ). Each of the driven pulleys (3 1 1) is fixed to the rotating shaft (300) of the corresponding piece (30). In addition, the active pulley (3 work) and its middle-driven pulley (311) are wound with a belt (3 i 2), and the remaining each driven pulley (31 1) and each adjacent The driven pulley (3 ^ = also has a belt (3 i 2 ) wound around it. This means that when the motor (3 2 ) is activated, the power take-off shaft (3 2 1 ) can be used, the driving pulley (3 i Q ), each -" moving pulley (3 1 1 ), and each belt (3 i 2 ) transmits the motor (such as = production (four) rotational force to drive the blades (3 〇) to rotate synchronously And the opening state of the opening σ ( 2 〇) or the opening degree of the heat-dissipating gate (3) is determined by the rotation slit of the = blade (3 Q ), wherein the belt transmission mechanism is used during operation No noise is generated. Please refer to the second figure, which indicates the two brackets on the inside of the casing (1) (the upper system is fixed with a fan (33), and the fan (33) is attached to the blade (3 when opened) Rotation produces an air flow, and when the blade (30) is closed, it stops rotating. Thus, as long as the personal computer main body has a heat dissipation control function = ff (2) The internal temperature is _ the positive reversal angle of the motor (32) =, less than the fine Π (3) (10) degrees can be heard according to the temperature surface. The person, the Tian ^ Temple, the system of heat dissipation (3) Yu Xu Or fully open, borrowing two = when = lower 'can control the coffee door (3) at a smaller opening or full closing ^ reduce the sound produced by the fan (3 3).
