Description

Technical Field

[0001] This invention relates to the field of cooling water channel structure technology for stamping dies, specifically an optimized cooling water channel structure for high-strength steel stamping dies for automobiles. Background Technology

[0002] High-strength steel for automobiles has become a core material for lightweight automotive design due to its excellent mechanical properties. However, during the stamping process, the mold is prone to local overheating due to continuous high temperature. This not only leads to quality problems such as warping and cracking of parts, but also accelerates thermal fatigue wear of the mold and shortens its service life.

[0003] For example, CN104275415B discloses a cooling water channel structure for hot stamping, including a forming die plate, a transition template and a water blocking block. The bottom surface of the forming die plate is provided with at least one cooling water tank, and the water blocking block is installed in the cooling water tank. The water blocking block and the cooling water tank are spaced apart to form a water flow channel. The transition template is provided with a transition water tank for collecting the cooling water in the water flow channel.

[0004] However, in existing technologies, the temperature monitoring of the cooling water circuit for stamping dies is limited to the main water circuit or the surface of the mold cavity. It does not specifically address areas prone to flow imbalance, such as branch water circuits and spiral sections. Furthermore, the data acquisition response is slow, making it difficult to keep up with the rapid temperature fluctuations during stamping operations. It also fails to correlate water flow with the temperature conduction differences between the water circuit, mold cavity, and parts, making it impossible to capture the true cooling status. The control mechanism is passive and crude, relying on preset fixed parameters and lacking a linkage feedback mechanism between temperature and flow. It can only roughly adjust the total flow of the main water circuit, failing to provide precise compensation for local temperature differences. Moreover, the adjustment response is lagging, making it difficult to match the rhythm of changing operating conditions. More importantly, the monitoring and control modules are independent of each other and do not form a closed-loop linkage. The abnormal temperature data detected cannot be directly converted into real-time control commands, but can only be recorded after the fact. As a result, problems such as local high temperatures and temperature differences between the inner and outer sides of the spiral section cannot be identified in a timely manner. The control is completely ineffective due to the lack of basis and the lag in action, which further exacerbates uneven cooling. Summary of the Invention

[0005] The purpose of this invention is to provide an optimized cooling water channel structure for high-strength steel stamping dies for automobiles, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an optimized cooling water circuit structure for a high-strength steel stamping die for automobiles, comprising a stamping mechanism, a fixed frame fixedly connected to the side of the stamping mechanism, a first temperature control mechanism and a second temperature control mechanism respectively installed inside the fixed frame, a cooling water circuit assembly fixedly connected to the end of the first temperature control mechanism, the stamping mechanism including a lower die, the lower die being fixedly connected to the cooling water circuit assembly, the cooling water circuit assembly including multiple cooling pipes and U-shaped connecting pipes, the multiple cooling pipes being located inside the lower die and interconnected through the U-shaped connecting pipes, multiple monitoring components installed on the surface of the cooling pipes, the monitoring components consisting of a temperature detection module and a flow monitoring module, and the monitoring components being used to monitor the temperature and flow rate of the coolant inside each cooling pipe, the first temperature control mechanism being used to supply coolant to the cooling water circuit assembly based on the monitoring data of the monitoring components, and the second temperature control mechanism being activated when the first temperature control mechanism cannot meet the cooling demand of the cooling water circuit assembly.

[0007] Preferably, the stamping mechanism includes a base, a frame is mounted on the upper part of the base, a pressure application component is mounted on the upper part of the frame, an upper die is mounted on the bottom of the pressure application component, and a lower die is located below the upper die and fixedly connected to the base.

[0008] Preferably, the first temperature control mechanism includes a first cooling box, inside which a first heat sink is installed, and a coolant circulation supply device is connected to the outside of the first cooling box. A second inlet pipe is installed at one end of the first heat sink, and a first inlet pipe is installed at the other end of the first heat sink. A first air-cooling component is fixedly connected to the end of the first inlet pipe. A first connecting pipe is fixedly connected to the outlet end of the first air-cooling component. The first connecting pipe is fixedly connected to a first circulation pump. A first outlet pipe is fixedly connected to the upper part of the first circulation pump. The first outlet pipe is fixedly connected to the inlet end of the cooling water circuit component, and the second inlet pipe is fixedly connected to the outlet end of the cooling water circuit component.

[0009] Preferably, the first temperature control mechanism includes three cooling modes. The first cooling mode is that the first cooling box and the first heat dissipation box cool the coolant circulating out of the cooling water circuit component. The second cooling mode is that the first air-cooling component cools the coolant circulating out of the cooling water circuit component. The third mode is that the first cooling mode and the second cooling mode simultaneously cool the coolant circulating out of the cooling water circuit component.

[0010] Preferably, the second temperature control mechanism includes a second cooling box, inside which a second heat dissipation box is installed, and a coolant circulation supply device is connected to the outside of the second cooling box. A fourth inlet pipe is installed at one end of the second heat dissipation box, and a third inlet pipe is installed at the other end of the second heat dissipation box. A second air-cooling component is installed at the end of the third inlet pipe. A second connecting pipe is fixedly connected to the outlet end of the second air-cooling component. The second connecting pipe is fixedly connected to a second circulation pump. A second outlet pipe is fixedly connected to the upper part of the second circulation pump. The second outlet pipe is fixedly connected to a first outlet pipe, and a first control valve is installed on the surface of the second outlet pipe.

[0011] Preferably, the second temperature control mechanism includes three cooling modes. The first cooling mode is that the second cooling box and the second heat dissipation box cool the coolant circulating out of the first temperature control mechanism. The second cooling mode is that the second air-cooling component cools the coolant circulating out of the first temperature control mechanism. The third mode is that the first cooling mode and the second cooling mode simultaneously cool the coolant circulating out of the first temperature control mechanism.

[0012] Preferably, a regulating main pipe is fixedly connected to the side of the second outlet pipe, a regulating branch pipe is fixedly connected to the end of the regulating main pipe, the regulating branch pipe is fixedly connected to the U-shaped connecting pipe, and a third control valve is installed at the end of each regulating branch pipe, and a second control valve is installed on the surface of the regulating main pipe.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the monitoring component, consisting of a temperature detection module and a flow monitoring module, is directly deployed on the surface of the cooling pipe. This allows for precise monitoring of the temperature and coolant flow rate at various points on the cooling pipe, solving the problems of insufficient monitoring in areas prone to flow imbalance and the inability to correlate temperature and flow data in existing technologies. It enables real-time capture of the actual cooling status. The primary temperature control mechanism supplies coolant to the cooling water circuit components based on the real-time data from the monitoring component, achieving coordinated control of temperature and flow. This eliminates the need for passive and crude preset parameter adjustment. Furthermore, when the cooling pipe temperature is too high and the primary temperature control mechanism is operating at full load, the secondary temperature control mechanism can be activated promptly to enhance heat exchange efficiency. The combined control of these two mechanisms improves the response speed of temperature regulation and avoids control lag. The overall structure, through the real-time monitoring of the monitoring component and the coordinated response of the primary and secondary temperature control mechanisms, effectively alleviates the problems of localized high temperatures and uneven cooling, ensuring the stability of the stamping operation and the quality of part forming.

[0014] 2. In this invention, a temperature control mechanism, through a cooling tank containing a heat sink, an air-cooling component, a circulating pump, and inlet pipes (number one and number two), forms a circulation path with the cooling water system. Three cooling modes are designed: independent operation of the cooling tank and heat sink, independent operation of the air-cooling component, and coordinated operation of both. This allows for flexible switching based on the real-time temperature requirements of the cooling water system, avoiding ineffective energy consumption in a single cooling mode. This multi-mode control design ensures precise cooling of the lower mold by the cooling water system, adapting to different stamping conditions and significantly improving energy efficiency. Simultaneously, the power supply and piping connection structure of the circulating pump ensure efficient and stable coolant circulation, providing reliable assurance for continuous and stable operation of the stamping mechanism and the quality of part forming. This increases the diversity of temperature control modes, thereby improving energy utilization.

[0015] 3. In this invention, the two cooling modes of the No. 2 temperature control mechanism—independent operation of the No. 2 cooling box and the No. 2 heat dissipation box, independent operation of the No. 2 air-cooling component, and coordinated operation of both—allow for flexible activation of the adaptation mode when the No. 1 temperature control mechanism cannot meet the cooling requirements of the cooling water circuit component, effectively compensating for the limitations of a single temperature control mechanism. The No. 4 liquid inlet pipe connects to the No. 2 liquid inlet pipe of the No. 1 temperature control mechanism, and the No. 2 liquid outlet pipe connects to the No. 1 liquid outlet pipe. Combined with the on / off control of the No. 1 control valve, the high-temperature coolant flowing from the No. 1 temperature control mechanism is cooled by the No. 2 temperature control mechanism and then flows back to the liquid inlet of the cooling water circuit component, forming a highly efficient and coordinated cooling cycle. This combination design of the "main-auxiliary" temperature control mechanism not only improves the flexibility and accuracy of cooling regulation through multiple mode selection but also enhances the cooling efficiency of the coolant through pipeline linkage, ensuring that the cooling water circuit component can continuously provide stable cooling for the lower die of the stamping mechanism, guaranteeing the continuity of high-strength steel stamping operations and the quality of part forming. 4. In this invention, when the monitoring component on the surface of a single cooling pipe detects excessively high local temperatures, a precise local cooling path is constructed by connecting the main regulating pipe to the side of the No. 2 outlet pipe, in conjunction with the regulating branch pipe at its end and the U-shaped connecting pipe, as well as the No. 3 control valve at the end of the regulating branch pipe and the No. 2 control valve on the surface of the main pipe. When the monitoring component on the surface of the cooling pipe detects excessively high local temperatures, the No. 1 control valve can be closed, the No. 2 control valve can be opened, and the corresponding No. 3 control valve can be opened and closed, allowing the coolant cooled by the No. 2 temperature control mechanism to directly enter the target cooling pipe through the regulating branch pipe, achieving directional and rapid cooling of the local high-temperature area. This solves the problem that traditional overall regulation is difficult to apply precise force to local anomalies. This design not only improves the accuracy and response speed of temperature regulation and avoids ineffective energy consumption, but also ensures cooling uniformity by precisely controlling the temperature of each area of ​​the cooling pipe, further guaranteeing the stamping stability of the lower mold and the forming quality of high-strength steel parts.

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

[0019] Example 1: Refer to Figures 1-7The diagram shows an optimized cooling water circuit structure for a high-strength steel stamping die for automobiles. It includes a stamping mechanism 1, with a fixed frame 2 fixedly connected to the side of the stamping mechanism 1. A first temperature control mechanism 3 and a second temperature control mechanism 4 are installed inside the fixed frame 2. A cooling water circuit assembly 5 is fixedly connected to the end of the first temperature control mechanism 3. The stamping mechanism 1 includes a lower die 15, which is fixedly connected to the cooling water circuit assembly 5. The cooling water circuit assembly 5 includes multiple cooling pipes 51 and U-shaped connecting pipes 52. The multiple cooling pipes 51 are located inside the lower die 15 and are interconnected through the U-shaped connecting pipes 52. Multiple monitoring components 6 are installed on the surface of the cooling pipes 51. Each monitoring component 6 consists of a temperature detection module and a flow monitoring module, and is used to monitor the temperature and flow rate of the coolant inside each cooling pipe 51. The first temperature control mechanism 3 supplies coolant to the cooling water circuit assembly 5 based on the monitoring data from the monitoring components 6. The second temperature control mechanism 4 is activated when the first temperature control mechanism 3 cannot meet the cooling requirements of the cooling water circuit assembly 5.

[0020] In this invention, the pressure application component 13 drives the upper mold 14 downward to cooperate with the lower mold 15 for stamping operations. The second temperature control mechanism 4 supplies coolant to the cooling water circuit component 5 for cooling, and the cooling water circuit component 5 cools the lower mold 15. During the production process, multiple monitoring components 6 monitor the temperature and coolant flow rate of various parts of the cooling pipe 51. When the temperature of the cooling pipe 51 is too high and the first temperature control mechanism 3 is running at full load, the second temperature control mechanism 4 enhances the heat exchange efficiency of the first temperature control mechanism 3 to quickly and fully cool the cooling water circuit component 5 and the lower mold 15. The combined regulation of the first temperature control mechanism 3 and the second temperature control mechanism 4 improves the response efficiency of temperature regulation. At the same time, the monitoring components 6 monitor the temperature of the cooling water circuit component 5 for real-time regulation.

[0021] The lower die 15 of the stamping mechanism 1 is fixedly connected to the cooling water circuit assembly 5. Multiple cooling pipes 51 of the cooling water circuit assembly 5 are connected via U-shaped connecting pipes 52 to achieve comprehensive cooling of the lower die 15. The monitoring component 6 (composed of a temperature detection module and a flow monitoring module) installed on the fixing frame 2 is directly deployed on the surface of the cooling pipes 51, which can accurately monitor the temperature and coolant flow rate of each part of the cooling pipes 51. This solves the problems of lack of monitoring in areas with high flow imbalance and inability to correlate temperature and flow data in existing technologies, and can capture the real cooling status in real time. The first temperature control mechanism 3 is based on the real-time data of the monitoring component 6. According to the supply of coolant to the cooling water circuit component 5, the temperature and flow rate are linked and controlled, which gets rid of the passive and crude preset parameter adjustment mode. When the temperature of the cooling pipe 51 is too high and the first temperature control mechanism 3 is running at full load, the second temperature control mechanism 4 can be activated in time to enhance the heat exchange efficiency. The combined regulation of the two improves the response speed of temperature regulation and avoids regulation lag. The overall structure effectively alleviates problems such as local high temperature and uneven cooling through the real-time monitoring of the monitoring component 6 and the coordinated response of the first temperature control mechanism 3 and the second temperature control mechanism 4, ensuring the stability of the stamping operation of the stamping mechanism 1 and the forming quality of the parts.

[0022] Example 2: According to Figures 1-7 As shown, the stamping mechanism 1 includes a base 11, a frame 12 is mounted on the upper part of the base 11, a pressure application component 13 is mounted on the upper part of the frame 12, an upper mold 14 is mounted on the bottom of the pressure application component 13, and a lower mold 15 is located below the upper mold 14 and fixedly connected to the base 11.

[0023] The first temperature control mechanism 3 includes a first cooling box 31, inside which a first heat sink 36 is installed, and the first cooling box 31 is externally connected to a coolant circulation supply device. A second liquid inlet pipe 37 is installed at one end of the first heat sink 36, and a first liquid inlet pipe 35 is installed at the other end of the first heat sink 36. The end of the first liquid inlet pipe 35 is fixedly connected to a first air-cooling component 34. The outlet end of the first air-cooling component 34 is fixedly connected to a first connecting pipe 33. The first connecting pipe 33 is fixedly connected to a first circulation pump 32. The upper part of the first circulation pump 32 is fixedly connected to a first outlet pipe 38. The first outlet pipe 38 is fixedly connected to the inlet end of the cooling water circuit component 5, and the second liquid inlet pipe 37 is fixedly connected to the outlet end of the cooling water circuit component 5.

[0024] The No. 1 temperature control mechanism 3 includes three cooling modes. The first cooling mode is that the No. 1 cooling box 31 and the No. 1 heat sink 36 cool the coolant circulating out of the cooling water circuit component 5. The second cooling mode is that the No. 1 air cooling component 34 cools the coolant circulating out of the cooling water circuit component 5. The third mode is that the first cooling mode and the second cooling mode cool the coolant circulating out of the cooling water circuit component 5 at the same time.

[0025] In this invention, when the No. 1 temperature control mechanism 3 adjusts the temperature of the cooling water circuit assembly 5, it can select the mode of independent operation of the No. 1 cooling tank 31 and the No. 1 heat sink 36, the mode of independent operation of the No. 1 air-cooled assembly 34, or the mode of simultaneous operation of the No. 1 cooling tank 31, the No. 1 heat sink 36 and the No. 1 air-cooled assembly 34, depending on the temperature of the cooling water circuit assembly 5. The stamping mechanism 1 supports the frame 12 via the base 11. The pressure application component 13 on the frame 12 drives the upper mold 14 to cooperate with the lower mold 15 on the base 11 to complete the high-strength steel stamping operation, providing operational support for cooling control. The first temperature control mechanism 3 forms a circulation path with the cooling water circuit component 5 through the first cooling box 31, which contains the first heat sink 36, the first air-cooling component 34, the first circulating pump 32, and the first liquid inlet pipe 35 and the second liquid inlet pipe 37. It is designed with three cooling modes: the first cooling box 31 and the first heat sink 36 operate independently, the first air-cooling component 34 operates independently, and so on. The two work together and can be flexibly switched according to the real-time temperature requirements of the cooling water circuit component 5, avoiding the ineffective consumption of energy in a single cooling mode. This multi-mode control design not only ensures the precise cooling effect of the cooling water circuit component 5 on the lower mold 15 and adapts to the heat dissipation requirements under different stamping conditions, but also significantly improves the energy utilization rate. At the same time, in conjunction with the power supply and pipeline connection structure of the No. 1 circulating pump 32, it ensures efficient and stable circulation of coolant, providing a reliable guarantee for the continuous and stable operation of the stamping mechanism 1 and the forming quality of parts, increasing the diversity of temperature regulation modes, thereby improving the energy utilization rate.

[0026] Example 3: According to Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the second temperature control mechanism 4 includes a second cooling box 41, inside which a second heat sink 46 is installed, and the second cooling box 41 is connected to a coolant circulation supply device. One end of the second heat sink 46 is equipped with a fourth inlet pipe 47, and the other end of the second heat sink 46 is equipped with a third inlet pipe 45. The end of the third inlet pipe 45 is equipped with a second air-cooling component 44. The outlet end of the second air-cooling component 44 is fixedly connected to a second connecting pipe 43. The second connecting pipe 43 is fixedly connected to a second circulation pump 42. The upper part of the second circulation pump 42 is fixedly connected to a second outlet pipe 48. The second outlet pipe 48 is fixedly connected to a first outlet pipe 38, and a first control valve 49 is installed on the surface of the second outlet pipe 48.

[0027] The second temperature control mechanism 4 includes three cooling modes. The first cooling mode is that the second cooling box 41 and the second heat sink 46 cool the coolant circulating out of the first temperature control mechanism 3. The second cooling mode is that the second air-cooling component 44 cools the coolant circulating out of the first temperature control mechanism 3. The third mode is that the first cooling mode and the second cooling mode simultaneously cool the coolant circulating out of the first temperature control mechanism 3.

[0028] In this invention, when the independent operation of the first temperature control mechanism 3 cannot meet the temperature regulation requirements of the cooling water circuit component 5, the second temperature control mechanism 4 is activated to assist the first temperature control mechanism 3 in temperature control. Similarly, the first temperature control mechanism 3 can be assisted by the independent operation mode of the second cooling box 41 and the second heat sink 46, the independent operation mode of the second air-cooled component 44, or the simultaneous operation mode of the second cooling box 41, the second heat sink 46, and the second air-cooled component 44. When the second temperature control mechanism 4 is activated, the first control valve 49 is opened, so that the high temperature coolant inside the second liquid inlet pipe 37 is cooled through the fourth liquid inlet pipe 47 and the second heat sink 46, and then through the second air cooling component 44 and the second connecting pipe 43, and finally through the second circulation pump 42 and the second liquid outlet pipe 48 back to the first liquid outlet pipe 38 for cooling circulation. The second temperature control mechanism 4 serves as an auxiliary control unit for the first temperature control mechanism 3. Its second cooling tank 41 houses the second heat sink 46, the second air-cooling component 44, the second circulating pump 42, and the third and fourth liquid inlet pipes 45 and 47, forming a complete auxiliary cooling path. It features three cooling modes: independent operation of the second cooling tank 41 and the second heat sink 46; independent operation of the second air-cooling component 44; and coordinated operation of both. This allows for flexible activation of the adaptation mode when the first temperature control mechanism 3 cannot meet the cooling requirements of the cooling water circuit component 5, effectively compensating for the limitations of a single temperature control mechanism. It is connected to the first temperature control mechanism 3 via the fourth liquid inlet pipe 47. The No. 2 inlet pipe 37 and the No. 2 outlet pipe 48 are connected to the No. 1 outlet pipe 38. With the switching control of the No. 1 control valve 49, the high-temperature coolant flowing out of the No. 1 temperature control mechanism 3 is cooled by the No. 2 temperature control mechanism 4 and then flows back to the inlet end of the cooling water circuit assembly 5, forming an efficient and coordinated cooling cycle. This combination design of the "main-auxiliary" temperature control mechanism not only improves the flexibility and accuracy of cooling regulation through multi-mode selection, but also enhances the cooling efficiency of the coolant through pipeline linkage, ensuring that the cooling water circuit assembly 5 can continuously provide stable cooling for the lower die 15 of the stamping mechanism 1, ensuring the continuity of high-strength steel stamping operations and the forming quality of parts.

[0029] Example 4: According to Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, a regulating main pipe 410 is fixedly connected to the side of the second outlet pipe 48, and a regulating branch pipe 412 is fixedly connected to the end of the regulating main pipe 410. The regulating branch pipe 412 is fixedly connected to the U-shaped connecting pipe 52, and a third control valve 413 is installed at the end of each regulating branch pipe 412. A second control valve 411 is installed on the surface of the regulating main pipe 410.

[0030] In this invention, during the overall cooling process, when the monitoring component 6 on the surface of a single cooling pipe 51 detects excessively high local temperatures, a precise local cooling path is constructed through the regulating main pipe 410 connected to the side of the second liquid outlet pipe 48, in conjunction with the regulating branch pipe 412 at its end fixed to the U-shaped connecting pipe 52, and the third control valve 413 at the end of the regulating branch pipe 412 and the second control valve 411 on the surface of the main pipe. When the monitoring component 6 on the surface of the cooling pipe 51 detects excessively high local temperatures, the first control valve 49 can be closed and the second control valve 411 can be opened. By opening and closing the corresponding No. 3 control valve 413, the coolant cooled by the No. 2 temperature control mechanism 4 can directly enter the target cooling pipe 51 through the regulating branch pipe 412, thereby achieving directional and rapid cooling of the local high-temperature area. This solves the problem that traditional overall regulation is difficult to apply force precisely to local abnormalities. This design not only improves the accuracy and response speed of temperature regulation and avoids ineffective energy consumption, but also ensures the uniformity of cooling by precisely controlling the temperature of each area of ​​the cooling pipe 51, further guaranteeing the stamping stability of the lower mold 15 and the forming quality of high-strength steel parts.

[0031] The operating method and working principle of this device are as follows: The pressure component 13 drives the upper mold 14 downward to cooperate with the lower mold 15 for stamping operations. The second temperature control mechanism 4 supplies coolant to the cooling water circuit component 5 to cool it down. The cooling water circuit component 5 cools the lower mold 15. During the production process, multiple monitoring components 6 monitor the temperature and coolant flow rate of various parts of the cooling pipe 51. When the temperature of the cooling pipe 51 is too high and the first temperature control mechanism 3 is running at full load, the second temperature control mechanism 4 enhances the heat exchange efficiency of the first temperature control mechanism 3 to quickly and fully cool the cooling water circuit component 5 and the lower mold 15. The combined regulation of the first temperature control mechanism 3 and the second temperature control mechanism 4 is used. When the No. 1 temperature control mechanism 3 adjusts the temperature of the cooling water circuit component 5, it can select the mode of independent operation of the No. 1 cooling box 31 and the No. 1 heat sink 36, the mode of independent operation of the No. 1 air-cooled component 34, or the mode of simultaneous operation of the No. 1 cooling box 31, the No. 1 heat sink 36 and the No. 1 air-cooled component 34, depending on the temperature of the cooling water circuit component 5. When the independent operation of the No. 1 temperature control mechanism 3 cannot meet the temperature regulation requirements of the cooling water circuit component 5, the No. 2 temperature control mechanism 4 is activated to assist the No. 1 temperature control mechanism 3 in temperature control. Similarly, the No. 2 cooling box 41 and the No. 2 heat sink 46 can be operated independently, the No. 2 air-cooled component 44 can be operated independently, or the No. 2 cooling box 41, the No. 2 heat sink 46 and the No. 2 air-cooled component 44 can be operated simultaneously to assist the No. 1 temperature control mechanism 3. During the overall cooling process, when the monitoring component 6 on the surface of a single cooling pipe 51 detects that the local temperature is too high, the first control valve 49 can be closed and the second control valve 411 can be opened. At the same time, by opening and closing the corresponding third control valve 413, the coolant cooled by the second temperature control mechanism 4 can directly enter the corresponding cooling pipe 51 through the regulating branch pipe 412 to regulate the temperature of the local high temperature area.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
