Cooling device suitable for semiconductor laser

Abstract

The invention provides a cooling device suitable for a semiconductor laser, and relates to the technical field of cooling devices. A laser shell is installed on the front side of the upper end face of the installation bottom plate, a supporting frame is fixed to the rear side of the upper end face of the installation bottom plate, and a heat absorption part is installed in the laser shell. A bearing is installed in the supporting frame, and the supporting frame is rotationally connected with a cooling part through the bearing. The water-cooled cooling device is provided with the buoyancy monitoring part and the small acousto-optic warning indicator, can automatically give an alarm when the cooling liquid is too little, is more reliable in operation through the arrangement of the buoyancy monitoring part, is low in manufacturing cost, is not liable to be damaged, and solves the problem that an existing water-cooled cooling device is not easy to damage when the cooling liquid is seriously lost. The water-cooled cooling device solves the problems that the existing water-cooled cooling devices cannot timely warn workers, and although some existing water-cooled cooling devices are provided with liquid level detection conduction alarm systems, the manufacturing cost is high, and the water-cooled cooling devices are easy to damage.

Description

technical field [0001] The invention relates to the technical field of cooling devices, in particular to a cooling device suitable for semiconductor lasers. Background technique [0002] Semiconductor lasers, also known as laser diodes, are lasers that use semiconductor materials as working substances. During the operation of the laser, a certain amount of heat will be emitted. If it is not cooled in time, it will affect the laser emission effect and service life of the laser. In this case, it must be cooled by a cooling device. [0003] In order to improve the cooling effect, some semiconductor lasers usually use water-cooled cooling devices. However, during the use of current water-cooled cooling devices, due to the continuous loss of cooling liquid, it is necessary to replenish the cooling liquid in time. However, when the cooling liquid loss is serious (for example, after more than half of the cooling liquid is lost), because the current cooling device cannot give warni...

Problems solved by technology

[0003] In order to improve the cooling effect, some semiconductor lasers usually use water-cooled cooling devices. However, during the use of current water-cooled cooling devices, due to the continuous loss of cooling liquid, it is necessary to replenish the cooling liquid in time. However, when the cooling liquid loss is serious (for example, after more than half of the cooling liquid is lost), because the current cooling device cannot give warnings to the staff in time, when the cooling liquid continues to be lost, it will reduce the heat dissipation effect on the electronic components inside the upper shell of the semiconductor laser, or even lose The cooling effect seriously affects the service life of the semiconductor laser, and although some water-cooled cooling devices are equipped with a liquid level detection conduction alarm system, the detection of the liquid level needs to be realized by sensors, which is not only expensive, but also easy damaged
