Technical Field

[0002] In the field of optical device applications, heat dissipation performance is a key indicator of device reliability and long-term stable operation. Traditional optical device heat dissipation designs generally rely on built-in cooling fans, which are directly fixed inside the housing with fasteners such as bolts. Although this design meets basic heat dissipation requirements to a certain extent, it exposes many inconveniences and limitations in actual applications.

[0003] From a maintenance perspective, when a cooling fan accumulates dust or malfunctions due to long-term operation, it needs to be cleaned or replaced. However, because the fan is firmly fixed inside the housing, technicians often need to disassemble the entire housing to access the fan. This process is not only time-consuming and labor-intensive, increasing maintenance costs, but also carries a high risk of misoperation. During the housing disassembly process, the slightest carelessness can damage or misalign other components within the housing, thereby affecting the overall performance and stability of the optical device. Therefore, we have improved this problem and proposed a heat dissipation assembly and optical device. Summary of the Invention
