Description

Technical Field

[0001] The utility model relates to the technical field of laser dazzling gun accessories, in particular to a water-cooling heat dissipation structure. Background Art

[0002] The laser dazzle gun uses 532nm green laser, which is the most sensitive to the human eye. It can not only illuminate objects miles away in low-light environments, but also warn potential targets at a long distance and control large groups of people. When irradiating the eyes, it can cause temporary blindness and dizziness, thereby quickly defeating the enemy without harming human life. The strong and dazzling green light beam can interfere with the enemy's visual sensors, making the opponent's attack or resistance instantly invalid.

[0003] When emitting a laser beam, the laser will generate heat. Overheating of the laser will trigger high temperature protection and reduce the life of the laser. The upgraded laser dazzling gun requires a longer range, a larger effective spot, and a longer continuous time. The range and spot problems can be solved by changing the optical lens, and optimization and improvement can be achieved. The old laser heat dissipation method uses TEC cooling to dissipate heat. The commonly used TEC cooling consumes too much power, about 30 watts, and the heat dissipation effect is not ideal, which affects the continuous working time. In addition, the cost of control components is not cheap, and the manufacturing cost is high.

[0004] For this purpose, a water cooling heat dissipation structure is specially proposed. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1: A water-cooled head cavity 8 is installed at the top of the installation base plate 1, a heat dissipation fan 7 is installed at the bottom of the water-cooled head cavity 8, a sealing plate 13 is installed at the top of the water-cooled head cavity 8, a laser 2 is installed on the top of the sealing plate 13, a water filling valve 5 is installed at the top of the integrated water pump water tank 6, a water inlet pipe 3 and a water outlet pipe 4 are respectively installed on one side of the integrated water pump water tank 6, a built-in temperature sensor 14 is installed inside the laser 2, an MPU microprocessor 15 is installed inside the laser 2, one end of the water inlet pipe 3 and the water outlet pipe 4 are connected to the top of the sealing plate 13, and the two ends of the water inlet pipe 3 and the water outlet pipe 4 are respectively connected to the inside of the water-cooled head cavity 8 and the integrated water pump water tank 6, the inside of the water-cooled head cavity 8 is filled with coolant 12, and the coolant 12 circulates inside the integrated water pump water tank 6 and the water-cooled head cavity 8.

[0021] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, since an integrated water pump water tank 6 and a water cooling head cavity 8 are respectively installed on the top of the installation base plate 1, and the integrated water pump water tank 6 and the water cooling head cavity 8 are connected through the water inlet pipe 3 and the water outlet pipe 4, the coolant stored in the integrated water pump water tank 6 can be injected into the water cooling head cavity 8 through the water pump inside the integrated water pump water tank 6. Since a laser 2 is installed on the top of the water cooling head cavity 8, the laser 2 will generate high temperature when emitting a laser, and the coolant 12 filled in the water cooling head cavity 8 can quickly absorb the high-temperature gas generated by the laser 2 when the laser 2 is in operation. Since a heat dissipation fan 7 is installed at the bottom of the water cooling head cavity 8, the heat dissipation fan 7 is used to dissipate the heat of the laser 2. Heat can be quickly discharged from the inside of the device, thereby increasing the cooling speed of the coolant 12. At the same time, the temperature of the coolant 12 inside the water-cooled head cavity 8 rises after absorbing heat. At this time, the coolant with increased temperature inside the water-cooled head cavity 8 is re-injected into the inside of the integrated water pump water tank 6 through the water outlet pipe 4 for cooling. At the same time, new coolant inside the integrated water pump water tank 6 will be injected into the inside of the water-cooled head cavity 8 again to absorb the heat generated during the operation of the laser 2, thereby avoiding the laser 2 from triggering high-temperature protection and causing the laser to be unusable. At the same time, it avoids the laser 2 from working in a high-temperature environment for a long time, thereby increasing the service life of the laser 2.

[0022] Since the laser 2 is installed with a built-in temperature sensor 14 and an MPU microprocessor 15, the internal working environment temperature of the laser 2 during operation can be detected through the built-in temperature sensor 14. When the built-in temperature sensor 14 detects that the temperature inside the laser 2 exceeds 25 degrees Celsius, the MPU microprocessor 15 can control the pump installed inside the integrated water pump water tank 6 and the cooling fan 7 installed at the bottom of the water-cooled head cavity 8 to work simultaneously, so as to circulate the coolant 12. At the same time, the rotation of the cooling fan 7 can increase the rate of heat dissipation for the laser 2. When the built-in temperature sensor 14 detects that the temperature inside the laser 2 drops below 25 degrees Celsius, the MPU microprocessor 15 will automatically stop the operation of the pump inside the integrated water pump water tank 6 and the cooling fan 7, making the entire device more intelligent and energy-saving.

[0023] An optical lens 10 is installed on one side of the mounting base plate 1, and a main control circuit board 9 is installed above the mounting base plate 1, a protective plate 11 is installed above the main control circuit board 9, the mounting base plate 1 is "L" shaped, and an integrated water pump water tank 6 is installed on the top of the mounting base plate 1, a wire is installed at one end of the laser 2, and one end of the wire is connected to one end of the optical lens 10.

[0024] Specifically, Figure 1 and Figure 2 As shown, after the laser 2 works to generate laser, the light source can be transported to the optical lens 10 through a wire at one end and diffused and emitted through the optical lens 10, so that the laser range can be longer and the effective light spot can be larger. Since a protective plate 11 is installed above the main control circuit board 9, the main control circuit board 9 can be protected by the protective plate 11 to avoid damage to the main control circuit board 9 and increase the service life of the device.

[0025] Working principle: When in use, fill the interior of the water-cooled head cavity 8 with coolant 12, open the water filling valve 5 above the integrated water pump water tank 6, and exhaust the air. Then, when the laser 2 is working, high temperature will be generated inside the laser 2. Since the laser 2 is equipped with a built-in temperature sensor 14 and an MPU microprocessor 15, the internal working environment temperature of the laser 2 during operation can be detected by the built-in temperature sensor 14. When the built-in temperature sensor 14 detects that the temperature inside the laser 2 exceeds 25 degrees Celsius, the MPU microprocessor 15 can control the pump installed inside the integrated water pump water tank 6 and the cooling fan 7 installed at the bottom of the water-cooled head cavity 8 to work simultaneously. Since the integrated water pump water tank 6 and the interior of the water-cooled head cavity 8 are circulatedly connected through the water inlet pipe 3 and the water outlet pipe 4, the coolant 12 stored in the integrated water pump water tank 6 can be injected into the interior of the water-cooled head cavity 8 through the pump inside the integrated water pump water tank 6. The coolant 12 can The high-temperature gas generated is quickly absorbed. Since a heat dissipation fan 7 is installed at the bottom end of the water-cooled head cavity 8, the heat can be quickly discharged from the inside of the device through the heat dissipation fan 7, thereby increasing the cooling speed of the coolant 12. At the same time, the temperature of the coolant 12 inside the water-cooled head cavity 8 rises after absorbing the heat. At this time, the coolant with the increased temperature inside the water-cooled head cavity 8 is re-injected into the inside of the integrated water pump water tank 6 through the water outlet pipe 4 for cooling. At the same time, the new coolant inside the integrated water pump water tank 6 will be injected into the inside of the water-cooled head cavity 8 again to absorb the heat generated when the laser 2 is operating, thereby avoiding the laser 2 from triggering high-temperature protection, resulting in the laser being unusable, and avoiding the laser 2 from working in a high-temperature environment for a long time, thereby increasing the service life of the laser 2. When the built-in temperature sensor 14 detects that the temperature inside the laser 2 drops below 25 degrees Celsius, the MPU microprocessor 15 will automatically stop the operation of the pump machine and the heat dissipation fan 7 inside the integrated water pump water tank 6, making the entire device more intelligent and power-saving.
