Description

Technical Field

[0001] This utility model relates to the field of laser processing technology, specifically to a cooling water circuit device with an annular groove welding structure. Background Technology

[0002] In high-power equipment such as laser processing and semiconductor manufacturing, the localized heat island effect on electrodes (a sudden temperature rise of 100-300℃ at the center) has become a core bottleneck restricting the lifespan and precision of the equipment. Traditional cooling devices achieve overall heat exchange through symmetrical flow channels or spiral pipes, but their core function is only to remove basic heat. They cannot break the temperature gradient dilemma of "high heat at the center and low temperature at the periphery," making the heat island area a key factor in equipment failure.

[0003] However, traditional cooling devices suffer from a vicious cycle of "difficult-to-break heat island - electrode ablation - soaring energy consumption" due to the delayed water flow around the symmetrical flow channel, the loss of focus in uniform heat exchange, and the energy inversion caused by the accumulation of flow rate, thus affecting the overall cooling effect of the electrode head. Utility Model Content

[0004] The purpose of this invention is to provide a cooling water circuit device with an annular groove welding structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling water circuit device with an annular groove welding structure, including a cooling plate, a cooling groove is provided inside the cooling plate, liquid guide ports are fixedly connected to the front and rear ends of the left side of the cooling groove, a heat conduction plate is installed on the top of the cooling plate, a screw groove is provided at the center of the upper surface of the heat conduction plate, and a connecting mechanism is also included, wherein the cooling plate is used for connecting and assembling the cooling plate and the heat conduction plate.

[0006] Preferably, an assembly plate is fixedly connected to the bottom end of the cooling plate, and rubber pads are provided on the contact surfaces of the cooling plate and the heat conduction plate.

[0007] Preferably, the cooling tank adopts a semi-biased asymmetric structure.

[0008] Preferably, the heat-conducting plate is made of copper, and the screw groove is used for mounting external electrode heads.

[0009] Preferably, the connecting mechanism includes guide grooves at both ends of the upper surface of the cooling plate, slots on the inner sides of the two guide grooves, positioning blocks fixedly connected to the left and right sides of the lower surface of the heat conduction plate, slots on the outer sides of the positioning blocks, movable grooves on the left and right sides of the top of the inner end of the cooling plate, partitions fixedly connected to the inside of the movable grooves, turntables rotatably connected to the outer sides of the movable grooves, pull ropes fixedly connected to the outside of the turntables, movable plates fixedly connected to the inner sides of the pull ropes, springs fixedly connected to the outer sides of the movable plates, and locking blocks fixedly connected to the inner sides of the movable plates.

[0010] Preferably, the card block and the card slot have the same specifications, both being trapezoidal.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This cooling water circuit device with an annular groove welding structure has a cooling tank inside the cooling plate. External cooling water can quickly enter the interior of the cooling tank through the liquid guide port on one side of the cooling tank. Guided by the tank body, it quickly reaches the center of the cooling plate and cools the heat island area. The cooling water also spreads quickly around the electrode point, achieving a leap in response speed, smoothing the temperature difference of the heat island, and reconstructing the system energy consumption, effectively improving the overall performance of the cooling device.

[0013] 2. This cooling water circuit device with an annular groove welding structure has positioning blocks fixed to the left and right sides of the bottom of the heat conduction plate. When the positioning block is inserted into the guide slide groove from the slot at the rear end of the guide slide groove and the heat conduction plate is rotated counterclockwise, the locking block in the cooling plate can be locked into the slot on the positioning block, thus fixing the position of the heat conduction plate at the top of the cooling plate. When the turntable on the cooling plate is rotated, the turntable pulls the pull rope to rewind, which can drive the locking block to be pulled out from the slot on the positioning block through the movable plate. Then, the heat conduction plate is rotated clockwise, which can complete the quick separation of the cooling plate and the heat conduction plate. The modular design improves the convenience of inspection and maintenance of the cooling water circuit device. Attached Figure Description

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.

[0022] like Figure 1-5 As shown, the present invention has the following specific embodiment.

[0023] Example 1

[0024] A cooling water circuit device with an annular groove welding structure includes a cooling plate 1, a cooling groove 2 is provided inside the cooling plate 1, liquid guide ports 201 are fixedly connected to the front and rear ends of the left side of the cooling groove 2, a heat conduction plate 3 is installed on the top of the cooling plate 1, and a screw groove 301 is provided at the center of the upper surface of the heat conduction plate 3. The liquid guide ports 201 can facilitate the rapid entry of cooling water into the interior of the cooling groove 2.

[0025] The bottom end of the cooling plate 1 is fixedly connected to the assembly plate 101, which facilitates the connection and assembly of the cooling device with external equipment.

[0026] Cooling tank 2 adopts a semi-biased asymmetric structure.

[0027] The heat conduction plate 3 is made of copper, and the screw groove 301 is used for the installation of external electrode heads. The copper material allows the heat conduction plate 3 to quickly conduct heat to the electrode heads.

[0028] Example 2

[0029] The difference from Embodiment 1 is that this embodiment discloses a connecting mechanism 4 for connecting and assembling the cooling plate 1 and the heat-conducting plate 3:

[0030] The connecting mechanism 4 includes guide grooves 102 at both ends of the upper surface of the cooling plate 1. Slots 103 are provided inside the two guide grooves 102. Positioning blocks 302 are fixedly connected to the left and right sides of the lower surface of the heat conduction plate 3. Slots 303 are provided on the outer sides of the positioning blocks 302. Movable grooves 401 are provided on the left and right sides of the top interior of the cooling plate 1. A partition 402 is fixedly connected inside the movable groove 401. A turntable 403 is rotatably connected to the outer side of the movable groove 401. A pull rope 404 is fixedly connected to the outer side of the turntable 403. A movable plate 405 is fixedly connected to the inner side of the pull rope 404. A spring 406 is fixedly connected to the outer side of the movable plate 405. A locking block 407 is fixedly connected to the inner side of the movable plate 405. The force applied to the locking block 407 can compress the spring 406 via 502. The reaction force of the spring 406 being compressed can push the locking block 407 back to its original position via the movable plate 405. When the screw groove 301 at the bottom of the heat conduction plate 3 is inserted into the slot 103 inside the guide slide 102, the locking block 407 can be inserted into the slot 303 on the positioning block 302, thus fixing the position of the heat conduction plate 3 at the top of the cooling plate 1. When the turntable 403 is rotated, the turntable 403 pulls the pull rope 404 to rewind. At the same time, the pull rope 404 can drive the locking block 407 to be pulled out from the slot 303 on the positioning block 302 via the movable plate 405, thereby completing the separation of the cooling plate 1 and the heat conduction plate 3.

[0031] Card block 407 and card slot 303 have the same specifications, both being trapezoidal. Furthermore, any content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0032] In this embodiment, during use: the threaded groove 301 at the bottom of the heat-conducting plate 3 is inserted into the slot 103 inside the guide slide 102 at the top of the cooling plate 1, and the heat-conducting plate 3 is rotated counterclockwise. At this time, the locking block 407 inside the cooling plate 1 can be inserted into the locking slot 303 on the positioning block 302, thus fixing the position of the heat-conducting plate 3 at the top of the cooling plate 1. Since the threaded groove 301 is provided at the top of the heat-conducting plate 3, the installation with the external electrode head can be completed, and the liquid outlet 201 outside the cooling plate 1 can be used to... Cooling water is quickly fed into the cooling tank 2 inside the cooling plate 1 and guided by the tank body of the cooling tank 2 to quickly reach the center of the cooling plate 1 and cool the heat island area. When it is necessary to disassemble the heat conduction plate 3, by rotating the turntable 403, the turntable 403 pulls the pull rope 404 to rewind. At the same time, the pull rope 404 can drive the locking block 407 to be pulled out from the locking slot 303 on the positioning block 302 through the movable plate 405. At this time, rotating the heat conduction plate 3 clockwise can quickly complete the disassembly of the cooling plate 1 and the heat conduction plate 3.
