[0002] Circuit boards serve as the support platform for electronic components. Through printed conductive lines and pads, electrical connections and mechanical fixation between electronic components are achieved. High-frequency microwave printed circuit boards are special circuit boards designed specifically for high-frequency signals and microwave frequency bands. Their core task is to efficiently transmit high-frequency signals.

[0003] A high-frequency microwave printed high-density HDI circuit board with patent application number 202222991093.1 facilitates the installation and positioning of the circuit board by setting a mounting bracket and a limiting plate. The rotation of the fan blades improves the heat dissipation efficiency of the circuit board. However, the dimensions of the mounting bracket and the limiting plate are fixed during use, which is not convenient for supporting and limiting circuit boards of different thicknesses and specifications, thus limiting the scope of installation and use. At the same time, the heat dissipation through the fan blades depends on the ambient temperature. When the external ambient temperature is high, the heat dissipation capacity is limited, which affects the service life. Utility Model Content

A fixing plate 8 is fixedly connected to the bottom of the first fixing bolt 6, and a second anti-slip pad 9 is fixedly connected to the bottom of the fixing plate 8. The circuit board body 10 is set on the top of the first anti-slip pad 45. The position of the fixing plate 8 can be easily adjusted by the two sets of first fixing bolts 6 and first nuts 7. With the cooperation of the first anti-slip pad 45 and the second anti-slip pad 9, it is easy to fix the circuit board body 10 of different thicknesses, which enhances the anti-slip and stability effect while reducing clamping damage to the circuit board body 10.

[0019] refer to Figure 1 and Figure 4 As shown, a cooling tank 14 is fixedly connected to the front surface of the support frame 3. The cooling tank 14 facilitates the storage of coolant.

A support 17 is fixedly connected to the bottom of the support frame 3. The support frame 3 is supported by two supports 17.

[0020] Working Principle: During use, the control positioning plate 42 slides under the support of the mounting frame 1 and, fixed by the connecting plate 43, drives the limit frame 44 to move. The distance between the two limit frames 44 is adjusted according to the size of the circuit board body 10. The connecting plate 2 is opened, and the circuit board body 10 is inserted into the inner side of the two limit frames 44 and placed on top of the first anti-slip pad 45. The two limit frames 44 support the circuit board body 10. Two sets of second fixing bolts 11 and second nuts 12 fix the two positioning plates 42 to the mounting frame 1, thereby fixing the position of the two limit frames 44 and enhancing the support stability. Two sets of first fixing bolts 6 and first nuts 7 respectively drive the two fixing plates 8 to descend, causing the fixing plates 8 to bring the second anti-slip pad 9 into contact with the top of the circuit board body 10. With the cooperation of the limit frames 44 and the first anti-slip pad 45, the circuit board body 10 is moved. The circuit board body 10 is clamped and fixed, and the control connecting plate 2 is closed. The first anti-slip pad 45 and the second anti-slip pad 9 enhance the anti-slip and stability effect while reducing clamping damage to the circuit board body 10. This facilitates the fixing of circuit board bodies 10 of different thicknesses, expanding the installation and application range. The airflow is filtered by the filter screen 51, and the three cooling fans 55 facilitate the acceleration of airflow and improve the heat dissipation uniformity. When the external temperature is high, the coolant in the cooling box 14 is transported through the connecting pipe 16 to the first support pipe 52, the U-shaped pipe 53 and the second support pipe 54, and then flows back to the cooling box 14 through the second support pipe 54, realizing the circulation of coolant. This reduces the internal temperature of the support frame 3, and the three cooling fans 55 are activated to blow the cooled air upwards, promoting better heat dissipation.
