[0002] A printed circuit board (PCB) is the abbreviation of Printed Circuie Board in English. Generally, a conductive pattern formed by printing circuits, printed components, or a combination of both on an insulating material according to a predetermined design is called a printed circuit, and a conductive pattern providing electrical connection between components on an insulating substrate is called a printed circuit. In this way, the finished board of the printed circuit or printed circuit is called a printed circuit board, also known as a printed board or printed circuit board.
[0003] During the processing of printed circuit boards, milling and drilling are required. Due to the high-speed friction between the milling device and the circuit board, heat is generated and the printed circuit board expands due to heat, so it is necessary to cool down the printed circuit board. The current devices have a high energy consumption for cooling the printed circuit board, so it is necessary to quickly cool down the printed circuit board. The common existing cooling method is air cooling.

Both ends of the rotating shaft 24 are sleeved in the bearings 12 on both sides. The wind blade 23 is arranged in the groove. The part of the wind blade 23 in the groove can be driven by the medium to rotate rapidly. The part of the wind blade 23 in the groove is not more than half, and is clamped in the bearing through the rotating shaft 24.
[0028] A control valve 3 is arranged at the bottom end of the air duct 1. The user can control the opening and closing of the air duct 1 through the control valve 3, and control the flow rate of the internal medium. With the air-driven detection device 2 provided, the wind blade 23 inside it can rotate under the drive of the medium in the air duct 1, that is, rotate between the bearings 12 around the rotating shaft 24. The user can observe the state of the wind blade 23 through the transparent shell 21 to determine whether the internal medium is in an exhaust air state. At the same time, the rotation speed of the wind blade 23 can also be observed to roughly determine the flow rate of the medium. The user can adopt a wind blade 23 structure with a bright color, and multiple groups of wind blade 23 structures are arranged on the outside of the rotating shaft 24.

A plurality of groups of wind blades 23 are arranged on the outer side of the rotating shaft 24. The plurality of groups of wind blade structures 23 can rotate at a uniform speed under the drive of the medium in the air duct 1, which is convenient for users to directly observe the rotation speed of the wind blades 23 and roughly determine the flow rate of the medium. The bottom end of the transparent shell 21 is provided with an interface 22 with a threaded structure on its outer wall, and the interface 22 is closed by a threaded cap. The inner side of the wind blade 23 is arranged in the air duct 1. Through the transparent shell 21 structure and the interface 22 structure at its bottom end, users can connect the interface 22 with a threaded structure to the detection end of an external medium detection and control device, and use the threaded structure therein for auxiliary connection and fixation. Therefore, the medium in the air duct 1 can be detected, which is convenient for real-time monitoring.
