[0002] In the modern automotive industry, hot stamping is a commonly used processing method in parts manufacturing. It is widely used in carbon fiber, glass fiber and plastic materials. The hot stamping process mainly uses upper and lower corresponding molds to press together, and the heating effect of the mold softens the material to facilitate shaping.

[0003] However, this results in a high surface temperature of the material after molding, so it is necessary to dissipate heat from the molded material to facilitate subsequent processing. At present, the heat dissipation of hot stamping parts is mainly achieved by air cooling. However, the cooling capacity of the refrigerant in air cooling is poor, and it cannot quickly dissipate heat from the parts, resulting in low heat dissipation capacity. In view of this, in-depth research was conducted on the above problems, which led to this case. Utility Model Content

[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] Please see Figure 1-3 This utility model provides an implementation scheme: In the modern automotive parts processing, hot pressing is an efficient processing method. However, the material after hot pressing is usually at a high temperature, so it is necessary to cool the hot-pressed workpiece to facilitate subsequent processing. Conventional cooling methods are often air cooling or natural cooling. However, this cooling method has low cooling efficiency and cannot effectively and quickly cool down automotive parts.

[0020] To address the aforementioned issues, this application discloses a high-efficiency heat dissipation and protection device for hot stamping of automotive parts, comprising a heat dissipation frame 1, which is a rectangular frame structure. A cooling tank 2 is provided on the heat dissipation frame 1, serving as a cooling zone. Two pairs of support legs are provided on the bottom surface of the heat dissipation frame 1 to increase the height of the device. A cooling channel 3 is provided on the cooling tank 2, serving as a conveying device for supporting the hot-pressed parts. The cooling channel 3 cools the parts through the cooling tank 2. Furthermore, a liquid cooling circulation assembly is provided on the heat dissipation frame 1, which is connected to the cooling tank 2. The liquid cooling circulation assembly can recycle and reuse the refrigerant used in the liquid cooling process.

[0021] For details, please refer to the attached instruction manual. Figure 1-3 It is known that the above-mentioned liquid cooling circulation assembly includes a liquid cooling tank 4, which stores refrigerant. The liquid cooling tank 4 is installed on the heat dissipation frame 1. A circulation pump 5 is connected to one side of the liquid cooling tank 4. The circulation pump 5 draws the refrigerant from the liquid cooling tank 4. A water supply pipe 6 is provided on one side of the circulation pump 5. Several branch pipes 7 are connected to one side of the water supply pipe 6. The refrigerant is supplied to the branch pipes 7 through the water supply pipe 6. The branch pipes 7 are arranged in parallel. By introducing the refrigerant to one side of the cooling tank 2, the automotive parts that pass through are cooled.

[0022] Furthermore, according to the instruction manual appendix Figure 1-3 It is known that the above-mentioned liquid cooling circulation assembly also includes several nozzles 9, which are connected horizontally and vertically with several branch pipes 7 to form a pipe network. Several nozzles 10 are installed on the nozzles 9 in a linear array, and the nozzles 10 correspond to the top surface of the cooling channel 3. A water collection tank is provided at the bottom of the cooling tank 2, and a return water pipe is connected to the bottom of the water collection tank. The return water pipe is connected to the liquid cooling storage tank 4. A heat exchange tube 12 is coaxially arranged inside the nozzle 9, and a cooler 13 is inserted into one end of the heat exchange tube 12.

[0023] In the specific implementation process, a network is formed by horizontally and vertically connecting several spray pipes 9 and several branch pipes 7 to supply the spray pipes 9 with the refrigerant, i.e., water. After the water enters the spray pipes 9, it exchanges heat with the heat exchange tubes 12 and is sprayed out from several nozzles 10. Then, it exchanges heat with the heat exchange tubes 12 through the cooler 13, taking away the heat and making the temperature of the sprayed water lower and the cooling effect more obvious. The cooled water will fall into the water collection tank, and the cooling water will be collected in the water collection tank and discharged through the return water pipe.

[0024] As a preferred option, a control valve 11 is provided on the water supply pipe 6. The control valve 11 is used to control the opening and closing of the water supply pipe 6. A top bracket 8 is connected to the top surface of the cooling tank 2. The spray pipe 9, the diversion pipe 7 and the cooler 13 are all installed on the top bracket 8.

[0025] As a preferred option, the heat dissipation frame 1 and the cooling tank 2 are connected by welding, and the liquid cooling tank 4 is connected to the heat dissipation frame 1 by a bracket. The liquid cooling tank 4 and the heat dissipation frame 1 are essentially separate, which facilitates the replacement of parts.

[0026] As a preferred option, the cooler 13 is a semiconductor refrigeration device. A heat-conducting rod 131 is connected to the cold end of the cooler 13. The heat-conducting rod 131 is inserted into the heat exchange tube 12. The cooler 13 and the heat exchange tube 12 are connected separately, which facilitates the disassembly and maintenance of the cooler 13. The cold end of the cooler 13 absorbs the heat from the heat exchange tube 12 through the heat-conducting rod 131, while the heat exchange tube 12 absorbs the heat from the refrigerant, thereby achieving the cooling of the refrigerant.

[0027] As a preferred option, the heat exchange tube 12 is further provided with several heat exchange fins 132 to improve the heat exchange effect. The length of the heat exchange tube 12 and the length of the nozzle 9 are greater than the width of the cooling channel 3, so that there is enough time for the incoming water to exchange heat.

[0028] In summary, this high-efficiency heat dissipation and protection device for hot stamping of automotive parts utilizes a liquid cooling circulation component combined with semiconductor refrigeration technology. It leverages the efficient heat exchange between the sprayed refrigerant and the heat exchange tube 12 to significantly improve cooling efficiency. The linear array nozzles 10 uniformly cover the cooling channels 3, ensuring uniform cooling. The modular design facilitates disassembly and maintenance. The refrigerant is recycled through a water collection tank, reducing resource consumption. Compared to traditional air cooling, this device increases the cooling rate by more than 50%, combining high efficiency and economy.
