Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for exposure modules, specifically a heat dissipation structure for an exposure module. Background Technology

[0002] An exposure module is a device used to project images or patterns onto the surface of a photosensitive material to achieve the exposure process. It is widely used in semiconductor manufacturing, printed circuit board (PCB) production, photovoltaic cell manufacturing, and other fields. The working principle of an exposure module is that light emitted from a light source is reflected by a mirror and enters a lens system. The lens system adjusts the focusing and imaging of the light, ensuring accurate transmission to the surface of the photosensitive material or object. Simultaneously, the control system controls the exposure time and light intensity, adjusting them as needed. Finally, the light is transmitted through a transmission system to the surface of the photosensitive material or object, completing the exposure process.

[0003] The core heat source of the exposure module is the light source (such as ultraviolet LEDs, mercury lamps, etc.), which has limited electro-optical conversion efficiency, with most of its energy being converted into heat. If this heat is not quickly dissipated, prolonged high temperatures will cause the light source filament to age, luminous efficiency to drop sharply, or even burn out prematurely. Simultaneously, under high temperatures, the resistance, capacitance, and other parameters of electronic components such as the drive circuit and sensors within the module will change abnormally, potentially leading to inaccurate exposure time control, malfunction in light intensity adjustment, or even short circuits, burning out the circuit board, and paralyzing the entire module. Therefore, a heat dissipation structure for the exposure module is proposed. Utility Model Content

The mounting bracket 16 is fixedly installed on the bottom inner wall of the through hole 15. The motor 17 is fixedly installed on the upper end of the mounting bracket 16. The motor 17 is located at the axis of the through hole 15. The output shaft of the motor 17 is fixedly connected to the rotating column 18. Multiple fan blades 19 are fixedly installed on the outer wall of the rotating column 18. The multiple fan blades 19 are arranged in a ring array with the axis of the rotating column 18 as the center.

[0019] When in use, an external power supply is connected to the motor 17, which will drive the rotating column 18 to rotate, thereby driving the fan blade 19 to rotate.

[0020] The housing 14 has four mounting holes 9 at its four corners. The upper sides of the single heat sink 3 are fixedly connected to extension plates 10. Two mating holes 11 are opened on the two extension plates 10 respectively. The four mating holes 11 are aligned with the four mounting holes 9.

At the same time, when the motor 17 is connected to an external power source, the motor 17 will drive the rotating column 18 to rotate, which in turn drives the fan blades 19 to rotate. The fan blades 19 will blow air toward the heat sinks 3 and flow out through the gaps between the heat sinks 3, thereby accelerating the air circulation and improving the heat dissipation efficiency. The filter 21 can filter the dust in the air, reducing the amount of dust adhering to the heat sinks 3 and thus affecting the heat dissipation of the heat sinks 3.
