Description

Technical Field

[0001] This invention relates to the field of gas generator technology, and more particularly to a cooling device for gas generator sets. Background Technology

[0002] During operation, gas generator sets generate a large amount of heat from the engine block and lubricating oil, which must be dissipated in a timely manner through a cooling system; otherwise, the unit may overheat, shut down, or even be damaged. Traditional cooling systems typically integrate the radiator and cooling fan directly next to the generator set, utilizing indoor air for heat exchange.

[0003] However, when the generator set is installed in a confined, poorly ventilated indoor space (such as a basement), the traditional integrated cooling system has the following problems: the hot air generated by the cooling fan cannot be discharged in time, causing the indoor temperature to rise sharply, further deteriorating the heat dissipation conditions and forming a heat cycle; the noise generated by the operation of the high-power cooling fan and water pump is amplified by reflection in the confined space, seriously exceeding the environmental protection and occupational safety limits.

[0004] Therefore, it is necessary to provide a new cooling device for gas generator sets to solve the above-mentioned technical problems. Summary of the Invention

A box cover is installed on the top of the water-cooled box, and a control box is installed on one side of the top of the box cover. A fixedly connected partition plate is installed in the middle of the heat-conducting plate boxes, dividing the interior of the heat-conducting plate boxes into an upper cavity and a lower cavity. Heat dissipation fins are embedded on both sides of the heat-conducting plate boxes, with one side of the heat dissipation fins exposed through the side wall of the water-cooled box. The top of the water-cooled box is equipped with... It has a spraying mechanism that sprays liquid onto the heat dissipation fins on the other side for evaporative cooling. Both ends of the water-cooled box are equipped with liquid guide pipes. One end of each liquid guide pipe is connected to a connecting pipe, which is connected to the coolant circulation pipeline of the gas generator. Branch pipe 1, branch pipe 2, branch pipe 3, and branch pipe 4 are connected sequentially on the outer wall of the liquid guide pipe. Branch pipe 1, branch pipe 2, branch pipe 3, and branch pipe 4 are connected to the upper and lower cavities of the heat conduction plate boxes on both sides. A switching mechanism is installed inside the liquid guide pipe. The switching mechanism includes a transmission rod, which is rotatably installed inside the water-cooled box. Both ends of the transmission rod are inserted into liquid guide pipes and each is equipped with a switching valve core. The switching valve cores switch the connection between branch pipe one, branch pipe two, branch pipe three, and branch pipe four and the coolant circulation pipeline. The water-cooled box is equipped with a driving component that drives the transmission rod to rotate. The driving component and the spraying mechanism are electrically connected to the control box.

[0007] Preferably, the switching valve core includes a sleeve, one end of which is sealed and fixedly connected to the transmission rod, and the other end of which is connected to the connecting pipe. An arc-shaped flow guide is fixedly installed on the outer wall of the sleeve. The arc length of the arc-shaped flow guide corresponds to a central angle of 90°. The sleeve has a through groove that communicates with the arc-shaped flow guide. A sealing ring is fixedly installed inside the liquid guide pipe. The arc-shaped flow guide is rotatably embedded in the sealing ring. The sealing ring has four through holes that correspond one-to-one with branch pipe one, branch pipe two, branch pipe three, and branch pipe four.

[0008] Preferably, branch pipe one and branch pipe two are respectively connected to the upper half cavity of the two heat-conducting plate boxes, and branch pipe three and branch pipe four are respectively connected to the lower half cavity of the two heat-conducting plate boxes. Branch pipe one, branch pipe two, branch pipe three and branch pipe four are distributed on the outer wall of the liquid guide pipe at 90° intervals along the circumference.

[0009] Preferably, the driving component includes a servo motor and a reducer, the output shaft of the servo motor is connected to the middle of the transmission rod through the reducer, and the servo motor is electrically connected to the control box.

[0010] Preferably, an auxiliary cooling fan is installed on the side of the heat-conducting plate box away from the water-cooling box, the airflow direction of the auxiliary cooling fan is towards the heat dissipation fins, and the auxiliary cooling fan is electrically connected to the control box.

[0011] Preferably, temperature sensors are installed in both the upper and lower cavities of the heat-conducting plate box. The temperature sensors are electrically connected to the control box and are used to monitor the temperature of the coolant in the heat-conducting plate box in real time and feed it back to the control box to control the operation of the switching mechanism.

[0012] Preferably, a sealed and waterproof structure is provided between the side wall of the water-cooled box and the heat dissipation fins passing through the side wall of the water-cooled box.

[0013] Preferably, the spraying mechanism includes water distribution pipes and spray heads. There are two sets of water distribution pipes, which are respectively installed on both sides of the top of the water-cooled box. There are multiple spray heads, which are evenly distributed at the bottom of the two sets of water distribution pipes. One end of the two sets of water distribution pipes is connected to a U-shaped pipe. A sealing head is installed at the end of one set of water distribution pipes. The water inlet end of the other set of water distribution pipes is connected to an external water source and a water pump.

[0014] Preferably, an overflow pipe is provided at the middle of one end of the water-cooled box, which is connected to an external water source for return flow.

[0015] Preferably, the top of the box cover has two through holes, and an exhaust fan is embedded in the through holes.

[0016] Compared with related technologies, the cooling device for gas generator sets provided by the present invention has the following advantages: 1. This invention provides a cooling device for a gas generator set. The heat conduction plate box is divided into upper and lower chambers by a partition plate. With the help of a switching mechanism, the mode of coolant entering the upper half chamber, the lower half chamber, or a combination of chambers can be flexibly switched. The coolant flow area can be adjusted according to different loads and ambient temperatures of the generator set to achieve zoned heat dissipation, avoid insufficient heat dissipation or heat dissipation redundancy in a single heat dissipation mode, improve the overall cooling effect, and adapt to different operating conditions of the generator set at high, medium and low. 2. This invention adopts a dual heat dissipation method that integrates air cooling and spray evaporative cooling: one side of the heat dissipation fins are exposed to achieve natural air cooling, while the other side of the heat dissipation fins are combined with a spray mechanism for evaporative cooling; evaporative cooling utilizes the principle of heat absorption by water vaporization, and the heat dissipation efficiency is much higher than that of simple air cooling. It can still ensure rapid cooling in high-temperature environments and when the unit is running at full load, thus solving the problem of weak heat dissipation under high-temperature conditions of traditional cooling devices. 3. In this invention, the double-group water distribution pipes and evenly arranged spray heads provide a wide spray coverage and uniform liquid spraying. The exposed heat dissipation fins inside the water-cooled box can all be in contact with the spray liquid, ensuring evaporative heat dissipation without dead angles. The U-shaped pipe connects the two water distribution pipes, resulting in a reasonable pipe layout and smooth water supply. The water-cooled box is equipped with an overflow pipe, which can realize the recycling of spray water, saving water and preventing water from overflowing inside the box, thus keeping the site environment clean.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0021] Please see Figures 1 to 8 The present invention provides a cooling device for a gas generator set, which includes: a water-cooled box 1, a heat-conducting plate box 2, a box cover 3, a spraying mechanism 4, a liquid guiding pipe 5, a connecting pipe 6, a switching mechanism 7, a driving component 8, and a control box 9.

[0022] In practice, the water-cooled box 1 is placed externally in a well-ventilated area (such as the roof of the generator room or a shady place), separated from the main body of the gas generator set. This effectively solves the noise problem of heat dissipation of the gas generator set in a narrow indoor environment. The coolant circulation pipeline of the main body of the gas generator is then connected to the connecting pipes 6 on both sides of the water-cooled box 1, so that the coolant in the coolant circulation pipeline of the gas generator can be introduced into the heat-conducting plate box 2 for circulation and heat dissipation. The heat-conducting plate box 2 uses a dual-mode heat dissipation of air cooling and liquid evaporation spraying mechanism 4, which can improve the overall cooling capacity of the water-cooled box. By switching mechanism 7, different cavities of the heat-conducting plate box 2 can be connected to the coolant circulation pipeline. The coolant circulation area can be adjusted according to different loads and ambient temperatures of the generator set to achieve zoned heat dissipation, avoid insufficient heat dissipation or heat dissipation redundancy in a single heat dissipation mode, improve the overall cooling effect, and adapt to different operating conditions of the unit, such as high, medium and low.

[0023] In a further proposed solution, depending on actual needs, staff can install locking casters on the bottom of the water-cooled box 1 to facilitate its movement, allowing for flexible arrangement of the water-cooled box 1 according to the site environment.

[0024] In an embodiment of the present invention, please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The water-cooled box 1 has heat-conducting plate boxes 2 symmetrically arranged on both sides. A box cover 3 is installed on the top of the water-cooled box 1. A control box 9 is installed on one side of the top of the box cover 3. A fixedly connected partition plate 21 is installed in the middle of the heat-conducting plate box 2, which divides the interior of the heat-conducting plate box 2 into an upper half-cavity 201 and a lower half-cavity 202. Heat dissipation fins 22 are embedded on both sides of the heat-conducting plate box 2. One side of the heat dissipation fins 22 are exposed through the side wall of the water-cooled box 1. A spray mechanism 4 is installed on the top of the water-cooled box 1, which sprays water onto the other side. The heat dissipation fins 22 on the side spray liquid for evaporative heat dissipation. Both ends of the water-cooled box 1 are equipped with liquid guide pipes 5. One end of the liquid guide pipe 5 is connected to a connecting pipe 6, which is connected to the coolant circulation pipeline of the gas generator through the connecting pipe 6. The outer wall of the liquid guide pipe 5 is connected in sequence with branch pipe 1 5a, branch pipe 2 5b, branch pipe 3 5c and branch pipe 4 5d. The branch pipe 1 5a, branch pipe 2 5b, branch pipe 3 5c and branch pipe 4 5d are connected to the upper half cavity 201 and lower half cavity 202 of the heat conduction plate box 2 on both sides. A switching mechanism 7 is installed inside the liquid guide pipe 5. The switching mechanism 7 includes a transmission rod 71, which is rotatably installed inside the water-cooled box 1. Both ends of the transmission rod 71 are inserted into the liquid guide pipe 5 and are equipped with switching valve cores 72. The switching valve cores 72 are used to switch the connection between the branch pipe 5a, the branch pipe 5b, the branch pipe 5c, and the branch pipe 5d and the coolant circulation pipeline. The water-cooled box 1 is equipped with a drive component 8 that drives the transmission rod 71 to rotate.

[0025] It should be noted that after the water-cooled box 1 is placed in a suitable area, the coolant circulation pipeline of the gas generator is connected to the connecting pipes 6 at both ends of the water-cooled box 1. When the gas generator is running, the coolant in the coolant circulation pipeline is introduced into the connecting pipe 6 at one end, and then guided by the switching valve core 72 of the switching mechanism 7 into any one of the branch pipes 5a, 5b, 5c, and 5d. Then it flows into the upper half cavity 201 or lower half cavity 202 of the corresponding heat transfer plate box 2, and then flows back into the gas generator through the connecting pipe 6 at the other end. Cooling circulation is achieved in the liquid circulation pipeline. When the coolant flows into the heat conduction plate box 2, the spray mechanism 4 is controlled by the control box 9 to spray liquid onto the heat dissipation fins 22 located on the liquid surface of the water cooling box 1. The liquid evaporates on the heat dissipation fins 22 and carries away the heat, thus achieving cooling. The heat dissipation fins 22 located below the liquid surface of the water cooling box 1 perform water cooling heat dissipation. When the coolant circulates in the circulation pipeline, the drive component 8 can drive the transmission rod 71 to rotate, which in turn drives the switching valve core 72 to rotate in the liquid guide pipe 5. The mode of coolant entering the upper half chamber 201 or the lower half chamber 202 can be flexibly switched to achieve alternating circulation heat dissipation in different zones.

[0026] For specific examples, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 The switching valve core 72 includes a sleeve 721. One end of the sleeve 721 is sealed and fixedly connected to the transmission rod 71. The other end of the sleeve 721 is connected to the connecting pipe 6. An arc-shaped guide shroud 722 is fixedly installed on the outer wall of the sleeve 721. The arc length of the arc-shaped guide shroud 722 corresponds to a central angle of 90°. The sleeve 721 has a through groove that communicates with the arc-shaped guide shroud 722. A sealing ring 73 is fixedly installed inside the liquid guide pipe 5. The arc-shaped guide shroud 722 is rotatably embedded in the sealing ring 722. Inside the 3, the sealing ring 73 has four through holes that correspond one-to-one with branch pipe 5a, branch pipe 5b, branch pipe 3c and branch pipe 4d. Branch pipe 1 5a and branch pipe 2 5b are respectively connected to the upper half cavity 201 of the two heat-conducting plate boxes 2, and branch pipe 3 5c and branch pipe 4 5d are respectively connected to the lower half cavity 202 of the two heat-conducting plate boxes 2. Branch pipe 1 5a, branch pipe 2 5b, branch pipe 3 5c and branch pipe 4 5d are all distributed on the outer wall of the liquid guide pipe 5 at 90° intervals along the circumference.

[0027] It should be noted that when the switching valve core 72 is switching, the transmission rod 71 drives the sleeve 721 of the switching valve core 72 to rotate, which simultaneously drives the arc-shaped guide shroud 722 to rotate and connect with different through holes of the sealing ring 73. This allows different branch pipes to be connected to the arc-shaped guide shroud 722, thereby adjusting one of the branch pipes 5a, 5b, 5c, or 5d to be connected to the coolant circulation pipeline. Thus, when the heat conduction plate box 2 is divided into the upper half chamber 201 and the lower half chamber 202 by the partition plate 21, different chambers are connected to the coolant circulation pipeline, realizing alternating heat dissipation circulation in different zones.

[0028] In this embodiment, the switching valve cores 72 inside the liquid guide pipes 5 at both ends of the water-cooled box 1 are aligned. Therefore, when the drive rod 71 rotates, the drive component 8 drives the arc-shaped guide shield 722 of the switching valve core 72 to rotate. This allows for synchronous adjustment of the arc-shaped guide shields 722 at both ends to connect with one of the corresponding branch pipes 5a, 5b, 5c, and 5d, achieving communication with the corresponding chamber of the heat-conducting plate box 2. Then, through one end of the sleeve 721, it connects to the connecting pipe 6, thus connecting to the cooling circulation pipeline of the gas generator set. By employing an integrated switching mechanism 7 of the drive rod 71 and the switching valve core 72, combined with the 90° central angle arc-shaped guide shield 722 and the circumferentially distributed 90° area... Four branch pipes allow for precise switching of coolant pathways between chambers with just a slight rotation of the transmission rod 71. The pipe switching structure is simple and reliable, enabling rapid adjustment of coolant flow direction and heat dissipation areas. Here, the sealing ring 73 cooperates with the switching valve core 72 to ensure the sealing performance of the internal pipe switching points of the guide pipe, preventing internal leakage and cross-contamination of coolant and ensuring stable coolant circulation. Furthermore, to prevent misalignment of the valve cores 72 at both ends due to twisting deformation of the transmission rod 71, which could lead to a short circuit in the circulation pipeline, the transmission rod 71 connecting the switching valve cores 72 at both ends is made of hollow spline shaft and tempered alloy steel. Its torsional stiffness is designed to be more than three times its rated operating torque to ensure stable transmission switching.

[0029] It is worth noting that the four branch pipes distributed in a circumferential 90° area, namely branch pipe 1 5a, branch pipe 2 5b, branch pipe 3 5c and branch pipe 4 5d, are distributed in the four quadrants of the liquid guide pipe 5. When the arc-shaped flow guide shroud 722 rotates in multiples of 90°, one of the branch pipes 1 5a, 2 5b, 3 5c and 4 5d is switched to connect with the switching valve core 72.

[0030] In a specific embodiment, please refer to Figure 1 , Figure 2 and Figure 8 The driving component 8 includes a servo motor 81 and a reducer 82. The output shaft of the servo motor 81 is connected to the middle part of the transmission rod 71 through the reducer 82. The servo motor 81 is electrically connected to the control box 9. Temperature sensors 24 are installed in both the upper cavity 201 and the lower cavity 202 of the heat conduction plate box 2. The temperature sensors 24 are electrically connected to the control box 9 and are used to monitor the temperature of the coolant in the heat conduction plate box 2 in real time and feed it back to the control box 9 to control the action of the switching mechanism 7.

[0031] It should be noted that when the drive unit 8 is working, it monitors the internal temperature of the upper half-cavity 201 and the lower half-cavity 202 of the heat-conducting plate box 2 in real time through the temperature sensor 24. Based on the temperature of the coolant in each cavity, it selects the half-cavity with the lowest temperature to connect to the circulation pipeline. The specific control logic involves numbering the temperature sensors 24 in the upper half-cavity 201 and the lower half-cavity 202 of the two heat-conducting plate boxes 2. For example, during coolant circulation, if the current connection is to the upper half-cavity 201 (number 1), and the coolant temperature in that cavity is too high, the coolant in the lower half-cavity 202 (number 2) will be the lowest temperature. If the temperature is low, the circulation pipeline is switched to the lower half of chamber 202 of No. 2, using the coolant in this chamber for cooling circulation. Then, according to the number, the servo motor 81 drives the transmission rod 71 to rotate precisely through the reducer 82, so as to realize the connection between the control switching valve core 72 and the corresponding sealing ring 73 through hole, thereby realizing the switching cooling circulation. This allows the coolant circulation area to be adjusted according to different loads and ambient temperatures of the generator set, realizing zoned heat dissipation, avoiding insufficient heat dissipation or heat dissipation redundancy of a single heat dissipation cooling circulation pipeline, improving the overall cooling effect, and adapting to different operating conditions of the unit at high, medium and low.

[0032] In an optional embodiment, please refer to Figure 1 , Figure 3 and Figure 4 An auxiliary cooling fan 23 is installed on the side of the heat conduction plate box 2 away from the water cooling box 1. The air blowing direction of the auxiliary cooling fan 23 is towards the heat dissipation fins 22, and the auxiliary cooling fan 23 is electrically connected to the control box 9.

[0033] It should be noted that while the heat conduction plate box 2 utilizes water cooling and evaporative cooling, the auxiliary cooling fan 23, controlled by the control box 9, provides air cooling to the outer heat dissipation fins 22. This air cooling further reduces the overall temperature of the heat conduction plate box 2 and the water cooling box 1. The auxiliary cooling fan 23, which is paired with the heat conduction plate box 2, blows air directionally onto the heat dissipation fins 22, enhancing the air cooling convection effect and further accelerating the heat dissipation speed of the heat dissipation fins 22. This ensures that the heat dissipation capacity can be supplemented in scenarios where the spray evaporation effect is poor, such as rainy days or low humidity, thus ensuring the stable operation of the device around the clock.

[0034] Furthermore, when the gas generator set is operating at low speed, the temperature requirements of the cooling cycle can be met by the air cooling of the auxiliary cooling fan 23. The spray mechanism 4 is then stopped. When the temperature rises, the spray mechanism 4 is then activated to cool down. Different cooling modes are selected according to the cooling requirements.

[0035] In this embodiment, a sealed and waterproof structure is provided between the side wall of the water-cooled box 1 and the heat dissipation fins 22 that pass through the side wall of the water-cooled box 1. The sealed and waterproof structure between the heat dissipation fins 22 and the side wall of the water-cooled box 1 prevents the sprayed liquid and coolant from leaking, improves the sealing performance of the device, and avoids water leakage from corroding parts and causing circuit failures.

[0036] In an optional configuration, the heat dissipation fins 22 on the heat conduction plate box 2 can be integrally welded to the heat conduction plate box 2, or they can be designed as detachable inserts (for example, the heat dissipation fins 22 can be fixed by screws or other detachable connections; no specific restrictions are imposed here, and the staff can design it reasonably according to the actual situation. When designing a detachable insert structure, a sealed and waterproof structure needs to be designed between the heat dissipation fins 22 and the heat conduction plate box 2 to prevent the coolant in the heat conduction plate box 2 from leaking). This allows for the disassembly and cleaning of the heat dissipation fins 22, and regular cleaning of the impurities attached to the heat dissipation fins 22 to avoid excessive impurities adhering to the surface of the heat dissipation fins 22, which would affect its normal heat dissipation performance.

[0037] In an optional embodiment, please refer to Figure 1 and Figure 4 The spraying mechanism 4 includes a water distribution pipe 41 and a spray head 42. There are two sets of water distribution pipes 41, which are respectively installed on the top two sides of the water-cooled box 1. There are multiple spray heads 42, which are evenly distributed at the bottom of the two sets of water distribution pipes 41. One end of the two sets of water distribution pipes 41 is connected to a U-shaped pipe 43. A sealing head 44 is installed at the end of one set of water distribution pipes 41. The water inlet end of the other set of water distribution pipes 41 is connected to an external water source and a water pump.

[0038] It should be noted that when the spraying mechanism 4 is in use, the external water pump is controlled by the control box 9 to supply water to the water distribution pipe 41, and the liquid is sprayed onto the heat dissipation fins 22 located above the liquid surface in the water-cooled box 1 through the spray head 42, so that the liquid evaporates and dissipates heat. With the use of the double set of water distribution pipes 41 and the evenly arranged spray heads 42, the spraying coverage is wide and the liquid is sprayed evenly.

[0039] In this embodiment, an overflow pipe 11 is provided at the middle of one end of the water-cooled box 1. The overflow pipe 11 is connected to an external water source for return flow. When the spray head 42 sprays liquid, the unevaporated liquid flows back into the water-cooled box 1. In order to ensure that half of the heat dissipation fins 22 inside the water-cooled box 1 are exposed for evaporative cooling, the returned liquid flows back to the external water source through the overflow pipe 11. This ensures that the liquid inside the water-cooled box 1 will not be higher than half the depth of the cavity of the water-cooled box 1. This allows half of the heat conduction plate box 2 to be located in the liquid inside the water-cooled box 1 and half to be exposed. This achieves a combination of stable water-cooled contact cooling and spray evaporative cooling, resulting in more stable and reliable heat dissipation. The overflow pipe 11 also enables the spray water to be circulated back, saving water and preventing water from overflowing from the box, keeping the site clean. During the water circulation process, after the spray water flows into the water-cooled box 1, it will be coarsely filtered by the filter screen and then flow out from the overflow pipe 11 for recycling.

[0040] In an optional configuration, a condensing mechanism can be added to the bottom of the water-cooled box 1. The condensing mechanism can be a plate or shell-and-tube structure, which is suspended and installed on the inside of the bottom plate of the box by a fixed bracket, maintaining a suitable gap with the bottom plate to prevent heat accumulation. The inlet and outlet of the condensing medium are respectively connected to an external cooling water source or a refrigeration unit to form an independent circulation loop, thereby further cooling the liquid in the water-cooled box 1.

[0041] In an embodiment of the present invention, please refer to Figure 1 and Figure 8 The top of the cover plate 3 has two through holes, and an exhaust fan 31 is installed in the through holes. By installing an exhaust fan 31 on the cover plate 3, the high temperature water vapor and hot air generated inside the water cooling box due to spraying and evaporation can be discharged in time, reducing the ambient temperature inside the box, improving the working environment of internal components and pipelines, delaying component aging, and extending the overall service life of the equipment. In order to prevent external dust and debris from flowing into the water cooling box 1 through the through holes, a protective filter screen is installed above the through holes for dust protection.

[0042] The working principle of the cooling device for gas generator sets provided by this invention is as follows: In use, the water-cooled box 1 is placed in a well-ventilated area. The coolant circulation pipe of the gas generator body is then connected to the connecting pipes 6 on both sides of the water-cooled box 1. When the gas generator is running, the coolant in the coolant circulation pipe is guided into the connecting pipe 6 at one end. Then, it is guided by the sleeve 721 and the arc-shaped guide shroud 722 of the switching valve core 72 of the switching mechanism 7, and guided into any one of the branch pipes 5a, 5b, 5c, and 5d. It then flows into the upper half cavity 201 or lower half cavity 202 of the corresponding heat-conducting plate box 2, and then flows back into the coolant circulation pipe of the gas generator from the connecting pipe 6 at the other end, thus achieving cooling circulation. When the coolant flows into the heat-conducting plate box 2, the spraying mechanism 4 is controlled by the control box 9 to spray liquid onto the heat dissipation fins 22 located on the liquid surface of the water-cooled box 1. The liquid evaporates on the heat dissipation fins 22 and carries away heat, thus achieving cooling. The fins 22 located below the liquid surface in the water-cooled tank 1 perform water cooling. When the coolant circulates in the circulation pipe, the internal temperature of the upper half-cavity 201 and the lower half-cavity 202 of the heat-conducting plate box 2 is monitored in real time by the temperature sensor 24. According to the temperature of the coolant in each cavity, the half-cavity with the lowest temperature is selected to be connected to the circulation pipe. (For specific control logic, the temperature sensors 24 in the upper half-cavity 201 and the lower half-cavity 202 of the two heat-conducting plate boxes 2 can be numbered. According to the number, the servo motor 81 drives the transmission rod 71 to rotate precisely through the reducer 82, so as to realize the connection between the control switching valve core 72 and the corresponding sealing ring 73 through the through hole) to achieve switching of cooling cycle. Thus, when the heat-conducting plate box 2 is divided into the upper half-cavity 201 and the lower half-cavity 202 by the partition plate 21, the switching mechanism 7 can flexibly switch the mode of coolant entering the upper half-cavity 201 or the lower half-cavity 202 to achieve partitioned alternating circulation cooling. Furthermore, while utilizing water cooling and evaporative cooling, the heat-conducting plate box 2 also uses the auxiliary cooling fan 23 controlled by the control box 9 to perform air cooling on the outer heat dissipation fins 22. This air cooling further reduces the overall temperature of the heat-conducting plate box 2 and the water-cooled box 1. The auxiliary cooling fan 23, which is equipped with the heat-conducting plate box 2, blows air directionally onto the heat dissipation fins 22, enhancing the air cooling convection effect and further accelerating the heat dissipation speed of the heat dissipation fins 22. An exhaust fan 31 is installed on the box cover 3 to promptly expel the high-temperature water vapor and hot air generated inside the water-cooled box due to spraying and evaporation, reducing the ambient temperature inside the box, improving the working environment of internal components and pipelines, delaying component aging, and extending the overall service life of the equipment.
