Explosion-proof integrated camera cooling method

The explosion-proof integrated camera is a convenient and practical monitoring product. The specific color and high sensitivity are unmatched by other explosion-proof cameras using CMOS sensors. However, different industries, different environmental areas, and different user requirements will choose the appropriate explosion-proof monitoring system according to their own application needs and actual conditions. Does the explosion-proof integrated camera need to be cut into the IP explosion-proof monitoring system, even if the IP monitoring system is blooming everywhere? , Explosion-proof integrated camera after many years of practical application and development, all aspects tend to be mature, driven by the growth in the security market still has room for its development, especially for some small and medium-sized projects, so explosion-proof integrated camera in The market will continue to occupy a place, and co-exist with the IP monitoring system.

The explosion-proof integrated camera system project has a growing demand for night vision. Explosion-proof integrated cameras have entered the mainstream market of explosion-proof security. Sales volume has been increasing day by day. Problems in the application of infrared night-vision technology are gradually exposed, often The poor heat dissipation of the camera is a major cause of failure of the explosion-proof integrated camera. It may damage the internal components of the explosion-proof integrated camera or even cause damage to the camera body. Therefore , the thermal problem of the explosion-proof integrated camera has not yet been completely resolved, but many of us have made corresponding improvements to this problem.

Note the heat dissipation method of explosion-proof integrated camera:

1. The use of explosion-proof integrated camera requires special attention in its structure installation and circuit design. Because the hot gas is rising, if the explosion-proof integrated camera is installed on the lower side, it will cause the increase of heat to affect the work of the camera, so the LED lamp should be installed more on the upper; In addition, the explosion-proof integrated camera uses the infrared lamp in the circuit design. When the explosion-proof integrated camera converts to night mode, the infrared light is automatically turned on to compensate the camera's image brightness in the night mode and improve the sharpness of the image. This is also the manufacturer's circuit design. A very important test.

2. Insulate the infrared lamp from the CCD. The CCD, lens, and infrared lamp can be isolated from each other by using a double glass plate. The stainless steel ring is used in the middle and protrudes outside. This can dissipate part of the heat and reduce the explosion-proof integrated camera. The ambient temperature of the instrument.

3, In addition, in the explosion-proof integrated camera to add heat sink or fan is also a good way, can be installed in the infrared light board under a layer of aluminum substrate, the use of thermal conductivity of the aluminum substrate to fully guide the heat to the shell. In view of this, because most of the previous infrared light panels were made of glass fiber plates, the thermal conductivity was low, and the thermal conductivity of the aluminum substrates used was relatively good. Since the explosion-proof integrated camera was installed on an aluminum substrate, the heat could be by explosion-proof integrated video camera bracket legs spread aluminum base plate for heat dissipation.

Laser Induced Breakdown Spectroscopy (LIBS): is an atomic emission spectroscopy technique. By focusing a pulse on the surface of a sample, while the energy intensity is higher than the breakdown threshold, the plasma emission is produced immediately. Based on the LIBS technology, sampling, atomization, excitation can be realized with the pulsed laser in the same system. The continuous bremsstrahlung and ion emission line are observed following the reduction of the plasma, and using the spectrometer to the samples.Its applications have been reported concerning metal analysis,soil analysis, agricultural product analysis, coal analysis, aqueous solution analysis, jewel authenticate and etc.
