The role of Kyushu space analysis microscope cold light source
We know that microscopes are used extensively in our lives, so what do we need when using microscope cold light sources? Let's talk about some of its applications.
Increasing the enhancement of the average heat transfer temperature difference, such as the arrangement of the heat exchange surface, causes the hot and cold fluid to flow in the opposite direction, and the average heat transfer temperature difference of this arrangement is the largest. The author sets the air inlet hole at the bottom plate of the cold light source fiber bundle output hole projection (better with the air deflector), so that the cold air entering the cold light source and the visible light containing a small amount of heat rays are reversely flowed to increase the visible light. The heat exchange between the internal heat rays and the cold air plays a considerable role in further reducing the temperature difference of the output visible light.
The strong cooling wind and strong cooling wind usually uses a fan to generate air flow, and the heat accumulated on the glass shell after being transmitted through the cold mirror is taken away, so that the glass shell reaches a heat balance at a certain temperature. The lower the cold air temperature through the air inlet, the higher the flow rate, the lower the heat balance temperature of the glass shell. Therefore, not only must there be a certain amount of air in the fan selection, but also a certain wind speed. Minimize the blockage of airflow during device placement.
The axial flow instrument fan should be installed behind the cold mirror, and the main shaft and the optical axis coincide, so that the airflow flows more evenly along the glass shell to obtain a better forced air cooling effect. The ordinary instrument fan is used to blow from the front of the cold mirror. Because the mirror has different blocking force on the airflow, it is easy to form eddy current, the flow rate is reduced, and the heat dissipation effect is poor. In this form, the wind deflector must be properly arranged.
The deep ellipsoid multi-layer interference dielectric film cold mirror is used for high reflection of visible light and high transmission of infrared light; the position of the lamp and the cold mirror is adjusted, and the high-intensity visible light with little heat radiation is obtained on the fiber bundle. With forced air cooling and full use of enhanced heat transfer technology, the output of visible light contains less heat rays to meet the high requirements for "cold light".
The above is some of the role of the microscope cold light source. We know that these effects will help our work. If you have any needs, please contact us.
