Description

Technical Field

[0001] The utility model provides a laser cladding water-cooled radiator, belonging to the technical field of laser cladding nozzle cooling. Background Technique

[0002] Laser cladding, also known as laser coating or laser cladding, is a new surface modification technology. It forms a filler cladding layer metallurgically bonded to the substrate surface by adding a cladding material to the substrate surface and using a high-energy density laser beam to melt and solidify it together with a thin layer of the substrate surface. The complete set of industrial laser cladding equipment includes a laser, a cooling unit, etc. During the laser cladding process, the distance between the bottom of the laser cladding nozzle and the molten pool is very close. The laser cladding nozzle has to withstand relatively high heat from laser reflection and molten pool thermal radiation. In order to prevent the laser cladding nozzle from being burned out during continuous processing, it is necessary to cool the nozzle. Therefore, a water-cooled radiator is essential in the cooling unit to cool the circulating water.

[0003] Existing water-cooled radiators can basically meet the usage requirements. When cooling and reducing the temperature of the circulating water, the currently used water-cooled radiators are mostly coil radiators. Its structure is that multiple pipes are arranged in parallel, and the overall shape is serpentine. Although it can well expand the heat dissipation area, since the circulating water flowing into the water-cooled radiator is relatively concentrated in the pipe and there is only one heat dissipation path, the circulating water in the pipe usually occupies most of the space in the pipe during the flow process. Inevitably, there will be quite a lot of circulating water in the center of the pipe, resulting in only one heat dissipation path when the coil radiator cools the circulating water, which will reduce the heat dissipation efficiency, and the circulating water near the center of the pipe often has an unsatisfactory heat dissipation effect. Based on this, the utility model provides a laser cladding water-cooled radiator. Summary of the Utility Model

[0004] The technical problem solved by the utility model is that when the coil radiator cools the circulating water, only one heat dissipation path will reduce the heat dissipation efficiency, and the circulating water near the center of the pipe often has an unsatisfactory heat dissipation effect.

[0005] To solve the technical problem, the technical solution provided by the utility model is: a laser cladding water-cooled radiator, which is applied to the cooling of a laser cladding nozzle, includes a water storage tank. An inlet chamber is provided above the water storage tank. A plurality of shunt heat dissipation pipes communicating with the top of the water storage tank are circumferentially arranged around the bottom of the inlet chamber. A plurality of heat dissipation fins are equidistantly arrayed on the shunt heat dissipation pipes. A frustum is provided at the inner bottom of the inlet chamber and located inside the shunt heat dissipation pipes. A rotating rod passing through the frustum is rotatably connected to the bottom of the inlet chamber. A spiral blade is provided on the upper rod body of the rotating rod above the frustum. A heat dissipation fan is provided at the bottom end of the rotating rod and located below the inlet chamber.

[0006] Further, a water pump is provided on one side of the water storage tank and is connected in communication. An inlet is provided at the top of the water inlet chamber above the spiral blade. The inlet is connected in communication with the outlet of the water circulation channel in the laser cladding nozzle. The water pump is connected in communication with the inlet of the water circulation channel in the laser cladding nozzle.

[0007] Further, both between the inlet and the outlet of the water circulation channel in the laser cladding nozzle and between the water pump and the inlet of the water circulation channel in the laser cladding nozzle are connected in communication through water pipes.

[0008] Further, heat dissipation fins are provided on the outer walls of both the water inlet chamber and the water storage tank.

[0009] Further, the cooling fan is arranged inside the shunt heat dissipation pipe. Rotating connections are provided between the bottom of the water inlet chamber, the top of the frustum, and the rotating rod through bearings.

[0010] Further, the frustum is in a shape that is smaller at the top and larger at the bottom, and a plurality of shunt protrusions are circumferentially provided on the outer wall of the frustum.

[0011] Advantages of the present utility model:

[0012] The circulating water flowing into the water inlet chamber flows obliquely downward along the outer wall of the frustum between the shunt protrusions, so that a single stream of circulating water can be divided into multiple streams and flow into each shunt heat dissipation pipe respectively. The circulating water cooling work can be carried out simultaneously in each shunt heat dissipation pipe. The wind generated by the rotation of the cooling fan blows through the shunt heat dissipation pipe and the heat dissipation fins, effectively improving the heat dissipation efficiency. The flow rate of the shunted circulating water is smaller, so that the shunted circulating water can flow downward along the inner wall of the shunt heat dissipation pipe, and thus it can effectively prevent too much circulating water in the center of the shunt heat dissipation pipe, and the heat dissipation effect is relatively good.

[0019] The present utility model will be further described below with reference to the accompanying drawings.

[0020] According to the attached Figure 1 、 4 、5 as shown: The present utility model provides a laser cladding water-cooled radiator, which is applied to the cooling of a laser cladding nozzle, including a water storage tank 1. There is a water inlet chamber 2 above the water storage tank 1. Heat dissipation fins 12 are provided on the outer walls of both the water inlet chamber 2 and the water storage tank 1. A plurality of shunt heat dissipation pipes 3 communicating with the top of the water storage tank 1 are provided around the circumference of the bottom of the water inlet chamber 2. A plurality of heat sinks 4 are equidistantly arranged in an array on the shunt heat dissipation pipes 3. A frustum 5 placed inside the shunt heat dissipation pipes 3 is provided at the bottom of the water inlet chamber 2. The frustum 5 is in the shape of a smaller top and a larger bottom. A plurality of shunt protrusions 14 are provided around the circumference of the outer wall of the frustum 5. Under the action of the heat dissipation fins 12 and the heat sinks 4, when the circulating water flows back into the water inlet chamber 2, the shunt heat dissipation pipes 3, and the water storage tank 1, heat dissipation and cooling work can be carried out.

[0021] According to the attached Figure 3 、 4 、5 as shown: The bottom of the water inlet chamber 2 is rotatably connected to a rotating rod 6 passing through the frustum 5. The bottom of the water inlet chamber 2, the top of the frustum 5 and the rotating rod 6 are rotatably connected through bearings 13, ensuring that the rotating rod 6 can rotate effectively. A helical blade 7 placed above the frustum 5 is provided on the upper rod body of the rotating rod 6. A heat dissipation fan 8 placed below the water inlet chamber 2 is provided at the bottom of the rotating rod 6. The heat dissipation fan 8 is arranged inside the shunt heat dissipation pipes 3. A water inlet 10 placed above the helical blade 7 is provided at the top of the water inlet chamber 2. The circulating water flowing back into the water inlet chamber 2 from the water inlet 10 will impact the helical blade 7. While impacting, the circulating water flows downward along the helical blade 7, causing the helical blade 7 to rotate, and then driving the rotating rod 6 to rotate, and further driving the heat dissipation fan 8 to rotate.

[0022] According to the attached Figure 2As shown in the figure: A water pump 9 is provided on one side of the water storage tank 1 and is connected in communication. The water inlet 10 is connected in communication with the outlet of the water circulation channel in the laser cladding nozzle. The water pump 9 is connected in communication with the inlet of the water circulation channel in the laser cladding nozzle. Both between the water inlet 10 and the outlet of the water circulation channel in the laser cladding nozzle and between the water pump 9 and the inlet of the water circulation channel in the laser cladding nozzle are connected in communication through a water pipe 11. The laser cladding nozzle equipped with a water circulation channel is an existing known and mature device, and will not be elaborated too much here. When the laser cladding nozzle needs to be cooled, by starting the water pump 9, the water in the water storage tank 1 is transported through the water pump 9 and the water pipe 11 into the water circulation channel of the laser cladding nozzle, realizing the cooling work of the laser cladding nozzle. Then the water flows back into the water inlet cavity 2 from the water pipe 11 through the water inlet 10 for subsequent circulating water cooling work.

[0023] Principle of the present utility model

[0024] During use, the circulating water flows back from the water circulation channel of the laser cladding nozzle through the water pipe 11 and the water inlet 10 into the water inlet cavity 2. The circulating water will impact the spiral blade 7 and flow downward along the spiral blade 7, causing the spiral blade 7 to rotate, and then driving the rotating rod 6 and the radiator fan 8 to rotate. The wind generated by the rotation of the radiator fan 8 blows through the shunt radiator pipe 3 and the radiator fins 4, and thus can assist in the heat dissipation work of the circulating water flowing into the shunt radiator pipe 3, effectively improving the heat dissipation efficiency. Under the action of the heat dissipation fins 12 and the radiator fins 4, the circulating water can dissipate heat when flowing back into the water inlet cavity 2, the shunt radiator pipe 3, and the water storage tank 1 in sequence. The circulating water flowing into the water inlet cavity 2 flows obliquely downward between the shunt protrusions 14 along the outer wall of the frustum 5, and thus can divide a single stream of circulating water into multiple streams and flow into each shunt radiator pipe 3 respectively, enabling the circulating water to dissipate heat simultaneously in each shunt radiator pipe 3, effectively improving the heat dissipation efficiency. The flow rate of the shunted circulating water is smaller, so that the shunted circulating water can flow downward along the inner wall of the shunt radiator pipe 3 and finally flow into the water storage tank 1 to converge, and thus can effectively prevent there from being too much circulating water in the center of the shunt radiator pipe 3, and the heat dissipation effect is relatively good.

[0025] The above describes the present utility model and its implementation manners. Such a description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the creative purpose of the present utility model, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
