Please refer to Fig. 1-4, the utility model provides the following technical solutions: a computer-based automatic control instrument cabinet, including a cabinet body 1 and a cabinet door 11 arranged on the front side of the cabinet body 1 and twisted with the cabinet body 1, the cabinet door 11 is provided with control buttons, warning lights and a display screen, and the four corners at the bottom of the cabinet 1 are fixed with supporting legs 12, which can make the cabinet 1 be raised and erected, so that the distance between the cabinet 1 and the ground There is a distance between them, so that a ventilation seat 3 can be set at the bottom of the cabinet body 1, and a ventilation fan 31 electrically connected to an external power supply can be installed by using the ventilation seat 3, so as to speed up the airflow velocity inside the cabinet body 1 and speed up the air flow inside the cabinet body 1. The heat dissipation rate of the electrical components is to prevent the internal temperature of the cabinet 1 from being too high, resulting in accelerated aging or high temperature damage of the electrical components. There are heat dissipation windows 13 on both sides of the cabinet 1 for ventilation and heat dissipation of the cabinet 1. The inner side of the top of 1 is fixed with a ventilating top cover 4, and the ventilating top cover 4 is used to cooperate with the ventilating fan 31 to realize the rapid circulation of the internal air flow of the cabinet body 1, and a protective shed cover 2 is provided on the top of the ventilating top cover 4, Cover is located at the top of ventilating top cover 4, prevents rainwater dust ventilating top cover 4 from entering cabinet 1 inside.

As shown in Figures 3 and 4, the heat dissipation window 13 includes an outer baffle 131 fixed on the outer wall of the cabinet body 1 and an inner baffle 132 fixed on the inner wall of the cabinet 1, the outer baffle 131, the inner baffle 132 and the cabinet body 1. The ventilation holes opened on the body 1 are connected to form a ventilation channel 133 .

Specifically, the end of the outer baffle 131 away from the cabinet body 1 is inclined downward, and the inner baffle 132 is an "L"-shaped structure, and the top is higher than the top of the ventilation channel 133; the setting of the outer baffle 131 can prevent external rainwater and dust To block the effect, the rainwater will drip down along the outer baffle 131 to avoid entering the cabinet 1. The inner baffle 132 can block the dust and reduce the dust from entering the cabinet 1 from the ventilation channel 133. The "L" shape structure of the baffle 132 makes dust be blocked by the inner baffle 132 and stay in the ventilation channel 133 .

As shown in FIG. 1 , screw holes 101 are provided at the top four corners of the cabinet body 1 ; they are used for installing the protective cover 2 .

As shown in Fig. 1 and Fig. 6, ventilating top cover 4 comprises the ventilating louver 41 that is arranged on ventilating top cover 4 top inboards, the structure of louver, makes ventilating top cover 4 can adjust the size of ventilating port according to use needs, flexible cavity, The peripheral side of the ventilation top cover 4 is provided with side ventilation openings 43, and the side ventilation openings 43 on the side can make the external air flow pass into the cabinet body 1 from the side ventilation openings 43, and the outer wall of the ventilation top cover 4 is bonded and fixed with a waterproof and breathable film 42.
