Abstract

The utility model belongs to the technical field of thermal spraying assistance, and particularly relates to a circulating water cooling tool. According to the circulating water cooling tool disclosed by the utility model, through unique design, a dual heat dissipation mechanism of the back of the base material and the coating surface is realized. The hollow square base body can rapidly conduct heat of the back of a workpiece into circulating water by means of the excellent heat conduction performance of red copper, and the first water flow driving circulating fan and the second water flow driving circulating fan connected in parallel with the first water flow driving circulating fan are arranged on one side of the coating face of the workpiece and driven by water flow to generate the air cooling effect and achieve collaborative cooling. Compared with a traditional single heat dissipation mode, the double heat dissipation mode has the advantages that the heat dissipation rate is greatly increased, the workpiece can be rapidly cooled after being sprayed every time, the time interval for waiting for cooling is greatly shortened, the machining period of the whole workpiece coating is remarkably shortened, and the machining efficiency is improved. The problem that workpieces cannot be delivered on time due to too long cooling time caused by high power of the spray gun is effectively avoided.

Description

Technical Field

[0001] This utility model belongs to the field of thermal spraying auxiliary technology, specifically relating to a circulating water cooling and temperature reduction tooling. Background Technology

[0002] Because the workpiece temperature often becomes too high during the thermal spraying process for ceramic coating, each spraying requires waiting for the workpiece temperature to drop after the previous spraying before continuing. This increases the processing time and thus the overall coating cycle. If the spray gun power is high during thermal spraying, the cooling time will also be extended, further slowing down the coating process and ultimately preventing on-time delivery of the workpiece.

[0003] Therefore, there is an urgent need for a tooling that can ensure safe, uniform and rapid physical cooling during the thermal spraying process to solve the problem of accelerated cooling of the workpiece during thermal spraying.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a circulating water cooling device.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A circulating water cooling fixture includes a chiller for reducing the temperature of the circulating water, a water pump for providing circulation power to the circulating water, and a cooling device for cooling the workpiece. The chiller, water pump, and cooling device are sequentially connected to form a circulating water system. The cooling device further includes a hollow square base for cooling one side of the workpiece and a first water flow driven circulating fan for cooling the other side of the workpiece. The hollow square base and the first water flow driven circulating fan are arranged in parallel.

[0008] Specifically, the water pump is an adjustable variable speed water pump, which can control the amount of water pumped by adjusting the speed; the first water flow drives the circulating fan, and the speed of the fan can be controlled by the amount of water flow.

[0009] Specifically, a water tank for storing circulating water is also provided between the chiller and the water pump.

[0010] Specifically, a water flow control valve is also provided between the water pump and the cooling device to control the water flow.

[0011] Specifically, the inlets of the hollow square base and the first water flow driven circulating fan are connected to the water pump through the first tee connector, and the outlets are connected to the chiller through the second tee connector.

[0012] Specifically, the hollow square base includes a base body and a square base top cover for easy maintenance. The base body has a threaded hole on the side near the square base top cover. The base body and the square base top cover are detachably connected by hexagonal screws and threaded holes.

[0013] Furthermore, a sealing strip is provided between the base body and the square base top cover.

[0014] Specifically, the hollow square substrate is made of copper, which is easy to dissipate heat, preferably copper. Copper has excellent thermal conductivity and can quickly dissipate heat.

[0015] Specifically, the first water-driven circulating fan includes a water tank and a fan assembly installed in the middle of the water tank. One end of the fan assembly is a water-driven rotating blade disposed in the water tank, and the other end is a fan blade for air-cooling the workpiece. The water-driven rotating blade and the fan blade are connected by a rotating shaft, which is rotatably fixed in the middle of the water tank.

[0016] Specifically, the cooling device also includes a second water-driven circulating fan that is connected in parallel with the hollow square base and the first water-driven circulating fan. The first water-driven circulating fan and the second water-driven circulating fan have the same structure.

[0017] Furthermore, the inlets of the hollow square base, the first water flow driven circulating fan, and the second water flow driven circulating fan are all connected to the water pump through the first four-way connector, and the outlets are all connected to the chiller through the second four-way connector.

[0018] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:

[0019] This utility model's circulating water cooling fixture, through its unique design, achieves a dual heat dissipation mechanism for both the back of the substrate and the coating surface. The hollow square substrate, leveraging the excellent thermal conductivity of copper, rapidly transfers heat from the back of the workpiece to the circulating water. Meanwhile, a first water-driven circulating fan and a parallel second water-driven circulating fan, located on the coating surface side of the workpiece, utilize water flow to generate a cooling effect and synergistically lower the temperature. Compared to traditional single-mode heat dissipation, this dual-mode significantly increases the rate of heat dissipation, allowing the workpiece to cool down rapidly after each spraying. This greatly reduces the waiting time for cooling, significantly shortening the overall workpiece coating processing cycle. It effectively avoids the problem of delayed workpiece delivery due to excessively long cooling times caused by high-power spray guns, thus significantly improving the company's production efficiency and delivery capabilities.

[0020] The quality of the coating largely depends on the temperature uniformity during the cooling process. The dual heat dissipation structure of this fixture works in tandem to achieve more uniform heat transfer during cooling. This uniform temperature distribution prevents localized overheating or undercooling during the bonding of the coating droplets. This characteristic effectively reduces the problem of unstable coating adhesion caused by uneven heating, ensuring a tight, strong, and uniform bond between the coating and the workpiece substrate, as well as between the droplets within the coating. This significantly improves the overall quality and durability of the coating, enabling the prepared ceramic coating to maintain good performance under various complex working conditions, extending the service life of the workpiece, and reducing maintenance costs and production losses caused by coating quality issues.

[0021] In the coating preparation process, the deposition of dummy powder has always been a thorny problem affecting coating quality and batch stability. The water-cooled circulating fan in this invention plays a crucial role. Its unique structural design uses water flow to drive the water-driven rotating blades in the fan assembly, which in turn drive the fan blades used for air-cooling the workpiece, creating a stable and uniform airflow on the workpiece coating surface. This airflow not only accelerates heat dissipation from the coating surface but also effectively disperses dummy powder that may be generated during spraying, preventing its deposition on the coating surface. Reducing dummy powder deposition means higher coating density and lower porosity, thus significantly improving key performance indicators such as coating hardness, wear resistance, and corrosion resistance. Simultaneously, by effectively controlling this unstable factor of dummy powder deposition, the coating preparation process between different batches becomes more stable and reliable, greatly ensuring the consistency of coating performance. This facilitates large-scale standardized production for enterprises, improving product quality controllability and market competitiveness. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Example 1

[0033] See Figure 1-4As shown, this embodiment provides a circulating water cooling fixture, including a chiller 1 for reducing the temperature of the circulating water, a water pump 8 for providing circulation power to the circulating water, and a cooling device for cooling the workpiece. The chiller 1, the water pump 8, and the cooling device are sequentially connected to form a circulating water system. The cooling device also includes a hollow square base 14 for cooling one side of the workpiece and a first water flow driven circulating fan 20 for cooling the other side of the workpiece. The hollow square base 14 and the first water flow driven circulating fan 20 are arranged in parallel. The hollow square base 14 contacts the body of the workpiece to cool it, and the first water flow driven circulating fan 20 blows on the coating to cool it. The two work together to ensure uniform cooling of the workpiece.

[0034] Specifically, the water pump 8 is an adjustable variable speed water pump, which can control the amount of water pumped by adjusting the speed; the first water flow driven circulation fan 20 can control the speed of the fan by the amount of water flow.

[0035] Specifically, a water tank 5 for storing circulating water is also provided between the chiller 1 and the water pump 8.

[0036] Specifically, a water flow control valve 11 for controlling the water flow is also provided between the water pump 8 and the cooling device.

[0037] Specifically, the inlets of the hollow square base 14 and the first water flow driven circulating fan 20 are connected to the water pump 8 through the first tee connector 23, and the outlets are connected to the chiller 1 through the second tee connector.

[0038] Specifically, the hollow square base 14 includes a base body and a square base top cover 15 for easy maintenance. The base body is provided with a threaded hole 18 on the side near the square base top cover 15. The base body and the square base top cover 15 are detachably connected by hexagonal screws 17 and threaded holes 18.

[0039] Furthermore, a sealing strip is provided between the base body and the square base top cover 15.

[0040] Specifically, the hollow square substrate 14 is made of copper, which is easy to dissipate heat, preferably copper. Copper has excellent thermal conductivity and can quickly dissipate heat.

[0041] Specifically, the first water-driven circulating fan 20 includes a water tank and a fan assembly installed in the middle of the water tank.

The water-driven rotating blade and the fan blade are connected by a rotating shaft, which is rotatably fixed in the middle of the water tank.

[0042] This embodiment also provides a method for operating the circulating water cooling device, as detailed below:

[0043] When preparing to begin thermal spraying of the workpiece, first turn on the chiller 1 for cooling, turn on the water pump 8 switch, and open the water flow control valve 11. The water pump 8 starts drawing water from the water tank 5. The circulating water comes out from the right-side interface 6 of the water tank, enters the water pump 8 through the water pump inlet 7, and after being pressurized by the water pump 8, it comes out from the water pump outlet 9 and enters the water flow control valve 11 through the water flow control valve inlet 10. The circulating water flow is adjusted according to actual needs through the water flow control valve 11. Then the circulating water comes out from the water flow control valve outlet 12 and is split through the first three-way connector 23. One path enters the hollow square base 14 through the square base inlet 13. The workpiece is cooled, and the water flows out through the square substrate outlet 16, then through the second three-way connector and into the chiller 1 through the chiller inlet 2; another path enters the first water-driven circulating fan 20 through the water-driven circulating fan inlet 19, driving the water-driven rotating blades to rotate and cool the coating of the workpiece. The circulating water flows out through the water-driven circulating fan outlet 21, then through the second three-way connector and into the chiller through the chiller inlet 2. After being cooled by the chiller 1, the circulating water flows out through the chiller outlet 3, passes through the water pipe 22, and then enters the water tank 5 through the left side interface 4 of the water tank, thus completing one cycle, i.e., continuously cooling the workpiece.
