Description

Technical Field

[0001] The utility model relates to the technical field of infrared sight housings, and particularly to a reliable heat dissipation device for an infrared sight housing. Background Technique

[0002] As is well known, with the continuous progress of existing optoelectronic technologies, infrared sights have been widely used in many fields such as military, security, and hunting due to their excellent performance. However, as the functions of infrared sights become increasingly complex, the internal integrated electronic components such as infrared detectors and signal processing circuits are also increasing day by day. These components will generate a large amount of heat during long-term operation. If heat cannot be effectively dissipated, it will not only reduce the working performance of the infrared sight, but may also cause equipment failures and even pose a threat to the safety of users.

[0003] Traditional heat dissipation methods for infrared sights mostly adopt natural heat dissipation or built-in fan heat dissipation. In the case of high power or long-term operation, the heat dissipation effect of natural heat dissipation often fails to meet the requirements. Although the built-in fan can force heat dissipation, the fixed position of the fan cannot be flexibly adjusted according to the heat dissipation requirements. Content of the Utility Model
