Description

Technical Field

[0001] This utility model relates to the field of laser temperature control technology, specifically a laser temperature control device. Background Technology

[0002] The output energy of a laser is significantly sensitive to ambient temperature. Specifically, when the ambient temperature is too high or too low, the output energy of the laser will show a marked decrease. This low energy directly affects the normal operating performance of the laser, thus adversely impacting the treatment effect.

[0003] In the prior art, the authorized announcement number CN210273001U discloses a laser cooling water temperature control device, including a laser body and a shell. The shell has an installation cavity inside. The left ends of the two sets of right flanges are detachably provided with left flanges by bolts. The left ends of the two sets of left flanges are provided with cooling water pipes.

[0004] A specially designed cooling water pipe system can effectively cool the laser, thereby achieving precise temperature regulation and control. Specifically, when the laser generates excessive heat during operation, the cooling water in the pipes circulates, carrying away heat from the laser surface to achieve cooling. However, during the temperature regulation process, the cooling water in the pipes inevitably absorbs heat from the heating device. This heat absorption interferes with the normal temperature regulation process, leading to reduced heating efficiency and affecting the overall efficiency of the temperature regulation process. Therefore, a temperature control device for the laser is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a temperature control device for lasers to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a temperature control device for a laser, comprising a laser body, an outer shell fixedly installed on the outside of the laser body, a wire connected to the tail of the laser body, a temperature control mechanism connected to the laser body, a PET heating film and a water cooling coil wound around the laser body, and a water tank disposed on the outside of the outer shell, a water cooler fixedly installed on the upper end of the water tank, a fan fixedly installed on the bottom of the water cooler, and a water vapor isolation mechanism fixedly installed at the water inlet end of the water cooling coil.

[0007] Preferably, a return pipe is installed between the water cooler and the water cooling coil, a water pump is connected to the return pipe, a water supply pipe is connected between the water-air isolation mechanism and the water tank, and a patch-type temperature sensor is installed on the surface of the laser body.

[0008] Preferably, the outer casing has an inlet / outlet hole, through which both the return pipe and the water supply pipe extend into the outer casing.

[0009] Preferably, one end of the return pipe is connected to the water tank, the other end of the return pipe is connected to the water cooling coil, one end of the water supply pipe is connected to the water tank, and the other end of the water supply pipe is connected to the water-air isolation mechanism.

[0010] Preferably, the water-air isolation mechanism includes an isolation valve body fixedly installed on a water-cooling coil, a piston rod slidably installed inside the isolation valve body, a gas flow channel and a water passage hole on the piston rod, with the gas flow channel located above the water passage hole, an armature block fixedly installed at the lower end of the piston rod, a spring installed inside the isolation valve body, an electromagnet fixedly installed at the bottom of the isolation valve body, and a sealing ring fitted on the piston rod.

[0011] Preferably, the piston rod has an installation groove, and the sealing ring is installed on the piston rod in the same groove.

[0012] Preferably, the bottom of the isolation valve body has an installation port, and the electromagnet is installed at the bottom of the isolation valve body through the installation port, with the electromagnet and the armature block aligned vertically.

[0013] Preferably, one end of the spring is connected to the bottom of the piston rod, and the other end of the spring is connected to the bottom of the isolation valve body. The isolation valve body has a movable groove, and the piston rod is movably mounted on the isolation valve body through the piston groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. In this application, when the laser body temperature is below a set threshold, the PET heating film power supply can be turned on to heat the laser body; when the laser body temperature is above the set threshold, the water pump can be started. After the water pump starts, the cooling water will circulate in the water-cooling coil, thereby cooling the laser body and achieving effective temperature control. When the high-temperature cooling water flows through the water cooler, the fan can be started to cool the cooling water returning to the water tank, realizing the recycling of the cooling water.

[0015] 2. In this application, an electromagnet can be activated before heating the laser using the PET heating film. Once activated, the electromagnet attracts the armature block, causing the piston rod to move downwards. When the piston rod reaches its lowest point, the water-cooling coil connects with the gas flow channel. At this time, the water pump can discharge any residual cooling water from the water-cooling coil, thus ensuring the heating efficiency of the PET heating film. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: As Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a temperature control device for a laser, including a laser body 1, an outer shell 2 fixedly installed on the outside of the laser body 1, a wire 3 connected to the tail of the laser body 1, a temperature control mechanism 4 connected to the laser body 1, and a water vapor isolation mechanism 5 fixedly installed at the water inlet end of the water cooling coil 402.

[0020] The laser body 1 can emit laser light. When the laser body 1 emits laser light, the outer shell 2 can prevent the laser from being interfered with by the external environment. The temperature control mechanism 4 can adjust the temperature of the laser body 1. When adjusting the temperature, the water vapor isolation mechanism 5 and the water pump 404 can discharge the cooling water in the water cooling coil 402 to ensure heating efficiency.

[0021] Example 2: Figure 2 and Figure 3As shown, the temperature control mechanism 4 is coiled around the PET heating film 401 and the water cooling coil 402 on the laser body 1, and the water tank 407 is set on the outside of the outer shell 2. A water cooler 405 is fixedly installed on the upper end of the water tank 407, and a fan 406 is fixedly installed on the bottom of the water cooler 405. A return pipe 403 is installed between the water cooler 405 and the water cooling coil 402. A water pump 404 is connected to the return pipe 403. A water supply pipe 408 is connected between the water vapor isolation mechanism 5 and the water tank 407. A patch temperature sensor 409 is installed on the surface of the laser body 1. An inlet and outlet hole is opened on the outer shell 2. The return pipe 403 and the water supply pipe 408 both extend into the outer shell 2 through the inlet and outlet hole.

[0022] Specifically, when the temperature of the laser body 1 is too low, the power supply of the PET heating film 401 can be turned on to heat the laser body 1. When the temperature of the laser body 1 is too high, the water pump 404 can be started. After the water pump 404 is started, the cooling water will circulate in the water cooling coil 402, thereby cooling the laser body 1 and achieving the purpose of temperature control of the laser.

[0023] In addition, the cooled high-temperature cooling water will flow through the water cooler 405. When the high-temperature cooling water flows through the water cooler 405, the fan 406 can be started to cool the cooling water that flows back into the water tank 407, thereby realizing the recycling of cooling water.

[0024] Example 3: Figure 2 , Figure 4 and Figure 5 As shown, the water-air isolation mechanism 5 includes an isolation valve body 501 fixedly installed on the water-cooling coil 402. A piston rod 503 is slidably installed inside the isolation valve body 501. A gas flow channel 502 and a water passage hole 505 are opened on the piston rod 503, and the gas flow channel 502 is located above the water passage hole 505. An armature block 506 is fixedly installed at the lower end of the piston rod 503. A spring 507 is installed inside the isolation valve body 501. An electromagnet 508 is fixedly installed at the bottom of the isolation valve body 501. A sealing ring 504 is sleeved on the piston rod 503. An installation groove is opened on the piston rod 503. The sealing ring 504 is installed on the piston rod 503 with the installation groove.

[0025] Specifically, during the cooling process, spring 507 pushes piston rod 503 upward. This upward movement causes water passage 505 to gradually align with water cooling coil 402 and water supply pipe 408. After alignment, cooling water in water supply pipe 408 can flow smoothly into water cooling coil 402, thereby achieving efficient cooling of the laser and ensuring that its operating temperature is maintained within a suitable range.

[0026] Before heating the laser, electromagnet 508 can be activated. Once activated, electromagnet 508 quickly attracts the armature block 506 it engages with. This attraction causes piston rod 503 to move downwards. When piston rod 503 reaches its lowest point, water-cooling coil 402 connects with gas channel 502. At this point, with the help of water pump 404, residual cooling water in water-cooling coil 402 is completely drained, ensuring no cooling water remains. This maximizes the heating efficiency of PET heating film 401, ensuring the laser quickly reaches the required temperature during heating.

[0027] Working Principle: The temperature of the laser body 1 can be detected by the patch temperature sensor 409. When the temperature of the laser body 1 is too low, the power supply of the PET heating film 401 can be turned on to heat the laser body 1. When the temperature of the laser body 1 is too high, the water pump 404 can be started. After the water pump 404 is started, the cooling water will circulate in the water cooling coil 402 to cool the laser body 1, thereby achieving the purpose of temperature control of the laser. The cooled water will flow through the water cooler 405. When the cooled water flows through the water cooler 405, the fan 406 can be started to cool the cooling water returning to the water tank 407, thereby achieving the recycling of cooling water. During cooling, the spring 507 will push the piston rod 503 upward, so that the water passage 505 is aligned with the water cooling coil 402 and the water supply pipe 408 respectively, so that the cooling water in the water supply pipe 408 can flow into the water cooling coil 402 to cool the laser. Before the PET heating film 401 heats the laser, the electromagnet 508 can be activated. After the electromagnet 508 is activated, it will attract the armature block 506, causing the piston rod 503 to move downward. After the piston rod 503 moves downward to the lowest point, the water cooling coil 402 will be connected to the gas flow channel 502. At this time, the water pump 404 can discharge the residual cooling water in the water cooling coil 402 to ensure the heating efficiency of the PET heating film 401.
