[0037] Working principle: The present invention is an intelligent composite roof ventilation and cooling device. The main body of the ventilation and cooling device is the roof ventilator 10. A steel beam frame 20 is set inside the roof ventilator 10. The steel beam frame 20 can not only enhance the strength of the roof ventilator 10, but also be used to install the auxiliary fan 30.

[0038] like Figure 2As shown in the figure, the arrows indicate the direction of airflow. The auxiliary fan 30 is equipped with an adjustable guide plate 34. By adjusting the position of the guide plate 34, the airflow inserted by the auxiliary fan 30 is directed towards the lower air outlet a between the drainage troughs 18 when the auxiliary fan 30 is working. This prevents the airflow from flowing towards the lower end face of the drainage troughs 18, thereby preventing airflow backflow. The airflow output from the lower air outlet a is guided by the lower rain shield 15 and can be output along the middle air outlet b on both sides of the lower rain shield 15, and finally discharged from the upper air outlet c between the upper rain shields 14.

[0039] Moreover, this composite roof ventilation and cooling device has multiple ventilation modes;

[0040] 1. Low-flow ventilation mode, suitable for winter, uses valve plate 19 to cover part of the lower air outlet a, reducing the airflow path, reducing the airflow from indoor to outdoor, and reducing indoor temperature loss;

[0041] 2. Medium flow ventilation mode, suitable for spring and autumn; by moving the valve plate 19, the lower air outlet a can be fully opened without obstructing it, ensuring normal airflow; the valve plate 19 is opened by hooking it with a long rod. Figure 7 Pulling down the upper ring 124 causes the pull rope 123 to drive the drive block 118 to move down, which causes the first link 119 and the second link 120, which were originally horizontal and locked together, to rotate. When the first link 119 and the second link 120 rotate, the compression spring 117 will cause the channel steel 111 to move, and the valve plate 19 fixed on the channel steel 111 will move away from the lower air outlet a.

[0042] 3. High-flow ventilation mode, suitable for summer. When all the lower air outlets a are open, but the indoor temperature is high, affecting the airflow, the auxiliary fan 30 is activated. The auxiliary fan 30 can accelerate the airflow.

[0043] The auxiliary fan 30 operates according to the set temperature. When the temperature sensor 40 returns to the set temperature of the auxiliary fan 30, it can automatically turn on or off, thus achieving intelligent control.

[0044] For example, the set temperature for the auxiliary fan 30 to turn on is 15℃, and the set temperature for turning off is 12℃. When the temperature sensor 40 reports a temperature of 15℃, the auxiliary fan 30 will automatically turn on. At the same time, the motor used for the fan inside the auxiliary fan 30 is a variable frequency motor, which can automatically adjust its rotation according to the temperature reported by the temperature sensor 40. The higher the temperature, the higher the speed of the fan inside the auxiliary fan 30, and the air volume and air pressure will increase with the rise in temperature. When the temperature reported by the temperature sensor 40 drops to 12℃, the auxiliary fan 30 will automatically stop running.

[0045] The embodiments are illustrative of the present application and are not intended to limit the present application. Any modification of the embodiments, which does not depart from the spirit and scope of the present application, is intended to be within the scope of the present application. The scope of the present application is defined by the claims.
