[0002] The thermal management device of laser electronic control is a key component to ensure that the laser and related electronic control systems operate in an efficient, stable and safe state. The laser and electronic control system will generate a large amount of heat during operation. If this heat cannot be effectively dissipated, it will lead to equipment performance degradation, shortened lifespan or even damage.
[0003] Common laser cooling devices generally only use air cooling and heat sinks, which are insufficient to provide cooling for high-power lasers. Common laser cooling devices generally do not have equipment to dissipate heat for the laser driver board alone. They often use a larger fan to dissipate heat for the laser and the laser driver board. This requires a lot of electricity and is not environmentally friendly. Therefore, a laser electronically controlled thermal management device is needed to solve the above problems. Utility Model Content

It often uses a larger fan to dissipate heat for the laser together with the laser driver board, which requires more electricity and is not environmentally friendly.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a thermal management device for laser electronic control, comprising a protective shell, a heat dissipation groove is provided on one side of the lower surface of the protective shell, a first cooling assembly is connected inside the heat dissipation groove, a laser body is threadedly connected to the upper surface of the first cooling assembly, the output end of the laser body extends to the outside of the protective shell, a laser electronic control driving board is installed on one side of the inner side of the protective shell, a first temperature sensor is installed near the first cooling assembly inside the protective shell, a second temperature sensor is installed near the laser electronic control driving board inside the protective shell, a detection end of the second temperature sensor is directly opposite to the laser electronic control driving board, a first heat dissipation fan is installed near the laser body on the upper surface of the protective shell, the first heat dissipation fan is located directly above the laser body, a second heat dissipation fan is fixedly installed near the laser electronic control driving board on the upper surface of the protective shell, the second heat dissipation fan is located directly above the laser electronic control driving board, both sides of the lower surface of the protective shell are fixedly connected with fixed legs, and a second cooling assembly is connected to one side of the fixed legs near the first cooling assembly.
[0006] Preferably, the first cooling assembly includes a heat dissipation guide plate, the detection end of the first temperature sensor is directly opposite to the heat dissipation guide plate, and the heat dissipation guide plate is fixedly connected to the bottom of the inner wall of the protective sleeve shell.
[0007] Preferably, the upper surface of the heat dissipation guide plate is threadedly connected to the laser body, and a heat sink is fixedly provided on the lower surface of the heat dissipation guide plate.
[0008] Preferably, the heat sink passes through the heat dissipation slot and extends to the outside of the protective sleeve.
[0009] Preferably, the second cooling assembly comprises a bellows, and a solenoid valve is installed at one end of the bellows.
[0010] Preferably, a cooling spray head is installed on the upper surface of the bellows near the first cooling assembly, and the liquid outlet end of the cooling spray head is located directly below the heat sink.
[0011] Technical effects and advantages of the utility model:
[0012] (1) The device can dissipate heat for the bottom of the laser body through the first cooling component and the second cooling component, and dissipate heat for the top of the laser body through the first cooling fan. When the first temperature sensor detects that the temperature of the heat dissipation guide plate is too high, the first cooling fan and the solenoid valve are turned on, and water is pumped through the cooling spray head through the solenoid valve and sprayed onto the surface of the heat sink. The heat dissipation efficiency of the heat sink is accelerated by evaporation of water and heat absorption. When the temperature of the laser electronic control drive board is too high, the second cooling fan can be turned on through the second temperature sensor to dissipate heat for the laser electronic control drive board.
[0013] (2) The device can provide heat dissipation for a laser body running at a relatively high power by means of the first cooling assembly, the second cooling assembly and the first heat dissipation fan, and can dissipate heat for the laser electronic control driver board by means of the second heat dissipation fan and the second temperature sensor, thereby solving the problem that common laser heat dissipation equipment generally only uses air cooling and a heat dissipation plate, which is insufficient to provide cooling for a high-power laser, and that common laser heat dissipation equipment generally does not have equipment for dissipating heat for the laser driver board alone, and often uses a larger fan to dissipate heat for the laser together with the laser driver board, which requires more electricity and is not environmentally friendly.
