Highly-efficient heat radiation night vision device

Abstract

The invention discloses a highly-efficient heat radiation night vision device with convenient laser temperature adjusting, comprising a night vision object lens, a camera, a laser machine, a power supply device, a memory, a display device, a control keyboard, and a control device. The camera is disposed behind the night vision object lens, and the laser machine is disposed at the front surface ofthe camera. Two laser machines are provided. The top surface of the laser machine is provided with a cooling piece, and the bottom surface of the laser machine is provided with a temperature sensor, and two side faces of the laser machine are respectively provided with a heat radiating piece. The heat radiating piece comprises a metal aluminum layer and a graphite layer from outside to inside. Theinner surface of the metal aluminum layer is provided with a zigzag-shaped first interlocking tooth, and the outer surface of the graphite layer is provided with a second interlocking tooth matchingwith the first interlocking tooth. The power supply device is disposed below the camera, and the memory is disposed at the side face of the camera, and the display device is disposed at the rear surface of the camera, and the control keyboard is disposed at the front surface of the display device.

Description

technical field [0001] The invention relates to a high-efficiency heat dissipation night vision device. Background technique [0002] With the development of economy and technology, the demand for night monitoring technology in monitoring in various industries is increasing. Night monitoring and evidence collection have become the primary issues that plague various security and technology defense fields. With the development of low-illuminance camera technology and infrared technology, the infrared night vision device formed by the combination of low-illuminance camera and infrared laser is widely used in the observation and monitoring of low-illuminance and all-black rings. Among them, the infrared laser is used for An infrared beam is sent forward, while a low-light camera is used to receive the reflected infrared radiation and form a clear image. [0003] Because the metal sheet has good heat conduction characteristics in the XYZ three-axis direction, copper, aluminum an...

AI Technical Summary

Problems solved by technology

However, the graphite sheet itself is relatively fragile and the thermal conductivity in the Z-axis direction is not good. These problems limit the application of graphite sheets in heat dissipation; in addition, the lasers of existing night vision devices usually do not have a cooling device, which affects the laser. In addition, existing night vision devices have technical problems such as complex structure, too many parts, poor versatility of parts, large production and assembly labor, and high maintenance costs
