Description

TECHNICAL FIELD

[0001] The application belongs to the field of power equipment boxes, and particularly relates to a power equipment box with high-efficiency heat dissipation. BACKGROUND

[0002] During the operation of the power equipment, the electronic components inside the power equipment continuously generate heat. If the heat cannot be dissipated in time, the temperature in the equipment box will rise, which affects the normal working performance and service life of the power equipment. Therefore, the heat dissipation of the power equipment box has always been the focus of the industry. At present, common heat dissipation methods of the power equipment box mainly include natural heat dissipation, forced air cooling and simple liquid cooling. The natural heat dissipation relies on the structural design of the equipment box to realize heat dissipation through heat exchange between the box wall and the external environment, and is suitable for low-power equipment. The forced air cooling is to install a fan in the equipment box to accelerate the air flow in the box, and the heat is discharged through the ventilation opening, and is widely used. The simple liquid cooling is to set a heat dissipation component containing cooling liquid in the equipment box, and the cooling liquid absorbs heat, and then the heat is dissipated through heat exchange with the box wall. However, the existing heat dissipation methods have obvious deficiencies in heat dissipation efficiency and adaptability. Especially for medium and high-power power equipment, the generated heat is large and concentrated, and the natural heat dissipation and forced air cooling are difficult to quickly discharge the heat, which easily leads to the local temperature in the equipment box being too high. In the simple liquid cooling method, the cooling liquid is often in a relatively static or simple circulation state, and the heat exchange with the heat generating component is not sufficient, and the heat absorbed by the cooling liquid cannot be efficiently transferred to the outside of the equipment box. When the heat accumulates to a certain extent, the heat dissipation capacity will decrease significantly, and it cannot meet the heat dissipation demand of the long-term stable operation of the medium and high-power power equipment.

Specific embodiments

[0017] The following examples are only for illustrative purposes, and are not intended to limit the scope of the application.

[0018] As Figures 1-6 shown, the application provides a power equipment box with high-efficiency heat dissipation function, which can include a power equipment box body 1, a metal column 2, a communication pipeline 3, a mounting plate 4, a communication assembly 5, a control assembly 6 and a water-cooled radiator 8.

[0019] The metal columns 2 are installed at the inner bottom of the power equipment box body 1, the metal columns 2 are connected with each other through the communication pipeline 3, the mounting plate 4 and the water-cooled radiator 8 are both installed on the outer wall of the power equipment box body 1, the communication assembly 5 is arranged between the communication pipeline 3 and the water-cooled radiator 8 and connected through the communication assembly 5, It should be noted that the plurality of metal columns 2 described in the embodiment are uniformly installed in a matrix on the inner bottom of the power equipment box body 1, and the installation positions of the metal columns 2 correspond to the core heat generating components of the power equipment in the box in the vertical direction. The metal columns 2 are made of aluminum alloy material to enhance the heat conduction performance. The internal cavity volume is designed according to the heating condition in the equipment box to ensure that the internal cold water can fully absorb the local heat. At the same time, the outer wall of the metal column 2 is fixedly sleeved with an arc-shaped cooling fin 21 along the height direction at equal intervals. The cooling fin 21 is integrally formed with the metal column 2. The fin spacing is reasonably set to avoid air convection obstruction, further expand the heat exchange area of the metal column 2 and the air in the box, and the plurality of metal columns 2 are connected in series through corrosion-resistant heat-resistant communication pipelines 3. The communication pipelines 3 are laid close to the inner bottom of the power equipment box body 1. The outer wall of the pipeline is wrapped with a heat preservation layer to prevent the cold water in the communication pipeline 3 from exchanging heat with the air in the box in advance, resulting in heat loss. The mounting plate 4 is made of stainless steel material and is detachably installed on the side of the outer wall of the power equipment box body 1 through bolts. The mounting plate 4 avoids the door opening side of the equipment box and the weak heat dissipation area. The mounting plate 4 is provided with mounting hole positions adapted to the subsequent components on the surface to ensure stable installation of the components. The water-cooled radiator 8 selects a double-fan air-cooled heat dissipation row to adapt to the heat dissipation demand of medium and high power equipment. The installation position of the water-cooled radiator 8 is on the same side of the mounting plate 4 and above the mounting plate 4. The air inlet surface of the water-cooled radiator 8 faces the direction with good ventilation outside the equipment box. The air outlet surface guides the airflow away from the power equipment box body 1 through a flow guide plate to avoid the hot air discharged by the heat dissipation row from flowing back to the vicinity of the power equipment box body 1. The control assembly 6 includes a controller 61, a mounting sleeve plate 62 and a temperature sensor 63. The controller 61 is installed on the outer wall of the power equipment box body 1. The mounting sleeve plate 62 is fixedly connected to the inner wall of the metal column 2. The temperature sensor 63 is installed on the inner wall of the mounting sleeve plate 62.

[0020] It should be noted that the controller 61 described in this embodiment is an industrial-grade microcontroller 61 with multi-channel signal acquisition and output functions. It is fixed to the dry and ventilated area on the outer wall of the power equipment box 1 through a waterproof mounting box. The installation position facilitates later debugging and maintenance. The controller 61 is equipped with status indicator lights and debugging interfaces on its surface, which can display the system operating status in real time and support on-site parameter adjustment. The mounting plate 62 is made of aluminum alloy with the same material as the metal column 2. It is fixed to the middle position of the inner wall of the metal column 2 by laser welding. Its shape fits the inner wall of the metal column 2 and has a reserved mounting groove for the temperature sensor 63. The contact surface between the mounting plate 62 and the metal column 2 is... Thermal grease is applied to reduce thermal resistance, ensuring that the water temperature inside the metal column 2 can be quickly transferred to the temperature sensor 63. The temperature sensor 63 is a high-precision digital temperature sensor with waterproof performance. Its detection end is embedded in the mounting groove of the mounting sleeve 62 and fixed with high-temperature resistant sealant. The sensor cable is led out from the pre-set wire hole on the inner wall of the metal column 2. The outer layer of the cable is wrapped with a wear-resistant insulating sleeve to avoid friction damage to the metal parts. The measurement range of the temperature sensor 63 covers the normal operating temperature range and the safety threshold range of the equipment. It can monitor the temperature change of the cold water inside the metal column 2 in real time and transmit the data to the controller 61, providing accurate basis for the start and stop control of the water circulation system.

[0021] Specifically, the metal column 2, through the high thermal conductivity of its aluminum alloy material and the expanded heat exchange area of ​​its outer arc-shaped heat sink 21, quickly absorbs the heat generated by the core heat-generating components inside the power equipment box 1. The internal cold water absorbs this heat and its temperature rises. A temperature sensor 63, mounted on the inner wall mounting plate 62 of the metal column 2, monitors the water temperature in real time and transmits the data to the controller 61. When the water temperature reaches a set threshold, the controller 61 activates the connecting component 5, allowing the warm water inside the metal column 2 to enter the water-cooled radiator 8 through the connecting pipe 3 and the connecting component 5. The cooled water, after being cooled by the dual-fan air-cooled radiator, then flows back to the metal column 2 through the connecting component 5 and the connecting pipe 3, forming a water circulation cooling system. When the water temperature... When the water temperature drops to the set lower threshold, the controller 61 shuts off the connecting component 5 to stop water circulation. At the same time, the insulation layer outside the connecting pipe 3 reduces heat loss during the transportation of cold water. The guide plate of the water-cooled radiator 8 prevents hot air backflow from affecting heat dissipation efficiency. This solution enhances the contact and exchange with heat through the corresponding arrangement of the metal column 2 and the core heat-generating component and the design of the arc-shaped heat sink 21. The absorbed heat is efficiently transferred to the outside of the equipment box through the water-cooled radiator 8 by water circulation. This solves the problem of insufficient heat dissipation efficiency and heat accumulation leading to a decrease in heat dissipation capacity of existing heat dissipation methods for medium and high power electrical equipment in the background technology, and meets the heat dissipation requirements for long-term stable operation of medium and high power electrical equipment.

[0022] Furthermore, the connecting component 5 includes an input pipe 51, an output pipe 52, a water pump 53, a first connecting pipe 54, and a second connecting pipe 55. The input end of the input pipe 51 and the output end of the output pipe 52 are respectively installed at the output end and input end of the connecting pipe 3. The water pump 53 is installed on the outer wall of the mounting plate 4. The input end of the water pump 53 is fixedly connected to the output end of the input pipe 51. The first connecting pipe 54 is provided between the output end of the water pump 53 and the input end of the water-cooled radiator 8, and the two are connected through the first connecting pipe 54. The second connecting pipe 55 is provided between the output end of the water-cooled radiator 8 and the input end of the output pipe 52, and the two are connected through the second connecting pipe 55.

[0023] It should be noted that the input pipe 51 and output pipe 52 described in this embodiment are both made of high-pressure resistant and corrosion-resistant engineering plastic material. The inner diameter of the pipes is adapted to the connecting pipe 3 to ensure smooth water flow. The connection parts of both pipes and the connecting pipe 3 adopt a socket structure and are fitted with a reinforced sealing ring to prevent water leakage. The water pump 53 is a miniature DC brushless water pump with low noise and high head characteristics. Its bottom is connected to the mounting plate 4 through a shock-absorbing pad to reduce the transmission of vibration during operation to the power equipment box body 1. The inlet and outlet of the water pump 53 are equipped with filter joints to prevent impurities in the water from entering the pump body and affecting its service life. The first connecting pipe 54 and the second connecting pipe 55 are made of flexible corrugated pipes, which can be flexibly adjusted according to the installation space. At the same time, the outer layer of the corrugated pipe is wrapped with a flame-retardant insulation layer to improve the safety of use. The connection between both pipes and the water pump 53 and the water-cooled radiator 8 is achieved through quick-connect couplings, which facilitates disassembly and maintenance in the future.

[0024] Specifically, when the controller 61 receives a water temperature exceeding the standard signal from the temperature sensor 63, the controller 61 controls the water pump 53 to start, while keeping the input pipe 51 and the output pipe 52 unobstructed. The warm water that has absorbed heat in the metal column 2 flows into the input pipe 51 through the connecting pipe 3, and is then pressurized by the water pump 53 and transported to the water-cooled radiator 8 through the first connecting pipe 54. The cold water cooled by the water-cooled radiator 8 enters the output pipe 52 through the second connecting pipe 55, and finally flows back to the connecting pipe 3 and is distributed to each metal column 2. This component solves the problems of low coolant circulation efficiency and inability to quickly remove heat in the simple liquid cooling method in the background technology. By providing power through the water pump 53 and matching the pipe structure, the coolant can be circulated efficiently, and the heat can be quickly transferred to the water-cooled radiator 8, thereby improving the overall heat dissipation efficiency.

[0025] Furthermore, it also includes an auxiliary component 7, which includes a heat dissipation window 71, a sealing plate 72, a cooling fan 73, a mounting side plate 74, a drive device 75, and a drive screw 76. The heat dissipation window 71 is installed on the bottom side of one side of the power equipment box body 1. One end of the sealing plate 72 is slidably engaged with the inner wall of the heat dissipation window 71. The cooling fan 73 is installed on the outer wall of the heat dissipation window 71. The mounting side plate 74 is fixedly connected to the bottom side of one side of the power equipment box body 1. The drive device 75 is installed on one side of the mounting side plate 74. One end of the drive screw 76 is rotatably connected to the inner wall of the heat dissipation window 71. The other end of the drive screw 76 is threaded through the sealing plate 72 and fixedly connected to the output end of the drive device 75.

[0026] It should be noted that the opening of the heat dissipation window 71 described in this embodiment adopts a grille structure. The size of the grille gap balances ventilation efficiency and dust prevention. The connection between the frame of the heat dissipation window 71 and the power equipment box body 1 is coated with waterproof sealant to prevent external rainwater from seeping in. The sealing plate 72 is made of high-strength alloy plate with rust-proof treatment. Sliders adapted to the guide groove are set on both sides of the plate. The outer side of the slider is wrapped with a wear-resistant rubber layer to reduce friction loss during sliding. The heat dissipation fan 73 is a silent axial flow fan with speed adjustment function. A protective mesh cover is installed on the outside of the fan to prevent foreign objects from being drawn in. The mounting side plate 74 has an L-shaped structure and is fixed to the power equipment box body 1 by welding. A waist-shaped hole is opened on its surface to facilitate fine adjustment of the installation position of the drive device 75. The drive device 75 is a micro stepper motor with forward and reverse rotation function. The motor output shaft and the drive screw 76 are connected by a coupling to ensure stable power transmission. The surface of the drive screw 76 is heat-treated, and the thread precision meets the transmission requirements. A deep groove ball bearing is set at the connection between the drive screw 76 and the inner wall of the heat dissipation window 71 to reduce rotational resistance.

[0027] Specifically, when the controller 61 determines that water circulation alone cannot meet the demand, such as when the water temperature continues to rise or the equipment power increases suddenly, the controller 61 controls the drive device 75 to start. The drive device 75 drives the drive screw 76 to rotate, causing the sealing plate 72 to slide along the guide groove of the heat dissipation window 71, opening the heat dissipation window 71. At the same time, the cooling fan 73 is started, which accelerates the air circulation inside and outside the power equipment box 1, expelling excess heat from the box. When the temperature inside the box drops to a safe range or water circulation can meet the demand, the controller 61 controls the drive device 75 to reverse, causing the sealing plate 72 to close the heat dissipation window 71 and turn off the cooling fan 73. This component solves the problem of poor adaptability and inability to cope with sudden high heat loads in the background technology of a single heat dissipation method. By cooperating with water circulation heat dissipation, a dual heat dissipation guarantee is formed, improving the heat dissipation capacity of the power equipment box under different operating conditions.

[0028] Furthermore, multiple heat sinks 21 are fixedly fitted onto the outer wall of the metal column 2 at equal intervals.

[0029] It should be noted that the heat sink 21 described in this embodiment is made of high-purity aluminum alloy and manufactured by extrusion molding. The cross-section of the heat sink 21 is wavy, which can further increase the contact area with air compared with the traditional flat heat sink 21. The thickness of the heat sink 21 is adapted to the diameter of the metal column 2 to ensure structural stability and not affect the installation of other components in the box. The connection between the heat sink 21 and the metal column 2 adopts an interference fit and is reinforced by high-temperature welding after assembly to prevent loosening during long-term use. At the same time, thermal paste is applied to the contact area between the two to fill the small gaps, reduce thermal resistance, and improve heat transfer efficiency. The spacing of multiple heat sinks 21 has been optimized by fluid dynamics simulation to maximize the number of heat sinks 21 and heat exchange area while ensuring smooth airflow.

[0030] Specifically, after the metal column 2 absorbs heat from the main body 1 of the power equipment box, part of the heat is transferred to the internal cold water through the metal column 2 itself, and the other part of the heat is transferred to the heat sink 21 on the outer wall through thermal conduction. The heat sink 21 uses its large surface area to quickly transfer heat to the surrounding air, and heat is dissipated through air convection. This structure solves the problem of limited heat dissipation efficiency of the metal column 2 relying solely on the internal cold water for heat absorption in the prior art. By adding heat sink 21 to expand the heat exchange path, the passive heat dissipation capacity of the metal column 2 is improved, the rate of cold water heating is slowed down, the start-up and shutdown frequency of the water circulation system is reduced, and energy consumption is reduced.

[0031] Furthermore, solenoid valves 511 are installed on both the input pipe 51 and the output pipe 52.

[0032] It should be noted that the solenoid valve 511 described in this embodiment is a normally closed two-position two-way solenoid valve 511. The valve body is made of stainless steel, which has the characteristics of water corrosion resistance and high temperature resistance. The nominal diameter of the solenoid valve 511 is consistent with the inner diameter of the input pipe 51 and the output pipe 52 to ensure unobstructed water flow. The coil of the solenoid valve 511 adopts a waterproof sealing design to avoid short circuits caused by condensation in the pipe or external moisture. The working voltage of the coil is matched with the output voltage of the controller 61 to ensure stable operation. The connection between the solenoid valve 511 and the pipe is a threaded connection. The interface is wrapped with Teflon tape and coated with sealant to ensure sealing performance. At the same time, a manual emergency switch is installed on the solenoid valve 511. When the controller 61 fails, the valve can be manually controlled to ensure emergency operation of the water circulation system.

[0033] Specifically, when the controller 61 starts the water circulation system, it synchronously sends an energizing signal to the solenoid valves 511 on the input pipe 51 and the output pipe 52. After the coil of the solenoid valve 511 is energized, it generates a magnetic field, which drives the valve core to move and open the valve, allowing water to flow smoothly through the input pipe 51 and the output pipe 52. When the water circulation system needs to be stopped, the controller 61 cuts off the power to the solenoid valve 511, and the valve core closes the valve under the action of the return spring, preventing water from flowing in the pipe. This structure solves the problem in the prior art that water may flow back in the pipe when the water circulation system stops, leading to waste of cold water or affecting the stability of the system. By precisely controlling the water flow through the solenoid valve 511, the reliable operation of the water circulation system is ensured, and cold water loss is avoided when the system stops, thus improving the utilization rate of water resources.

[0034] Furthermore, a guide groove for sliding of the sealing plate 72 is provided at one end of the heat dissipation window 71, and a sealing strip is installed on the inner wall of the heat dissipation window 71.

[0035] It should be noted that the guide grooves described in this embodiment are opened on both sides of the inner wall of the heat dissipation window 71. The cross-section of the guide groove is U-shaped, and the width of the groove is adapted to the thickness of the slider of the sealing plate 72. The length of the guide groove is slightly greater than the width of the sealing plate 72 to ensure that the sealing plate 72 can fully open or close the heat dissipation window 71. Solid lubricant is applied to the inner wall of the guide groove to reduce the frictional resistance when the sealing plate 72 slides and extend its service life. The sealing strip is made of EPDM rubber with good aging resistance and elasticity. It is fixed to the part of the inner wall of the heat dissipation window 71 that contacts the sealing plate 72 by means of a slot embedding method. The cross-section of the sealing strip is hollow arc-shaped. When the sealing plate 72 is closed, it can fill the gap between the sealing plate 72 and the heat dissipation window 71 through its own elastic deformation. At the same time, the surface of the sealing strip is waterproofed to prevent rainwater or moisture from seeping into the box through the gap.

[0036] Specifically, when the drive device 75 drives the sealing plate 72 to slide, the sliders on both sides of the sealing plate 72 move along the guide groove. The guide groove provides a stable movement trajectory for the sealing plate 72, preventing the sealing plate 72 from shifting or getting stuck, and ensuring that the heat dissipation window 71 opens and closes smoothly. When the sealing plate 72 closes the heat dissipation window 71, the edge of the sealing plate 72 squeezes the sealing strip, and the sealing strip undergoes elastic deformation, tightly fitting the contact surface between the sealing plate 72 and the heat dissipation window 71, blocking the airflow between the inside and outside of the box, and preventing external dust and rainwater from entering the box. This structure solves the problems of the heat dissipation window 71 not opening and closing smoothly and the poor sealing performance after closing in the prior art. The guide groove ensures the stable operation of the sealing plate 72, and the sealing strip improves the sealing effect of the heat dissipation window 71, taking into account both heat dissipation requirements and the dustproof and waterproof performance of the equipment box.

[0037] Furthermore, a heat dissipation vent is installed on the top of the power equipment box body 1, and a dustproof net is fixedly connected to the inner wall of the heat dissipation vent.

[0038] It should be noted that the heat dissipation vent described in this embodiment is located at the center of the top of the power equipment box body 1. The vent is rectangular in shape, and its size is designed according to the volume and heat generation power of the equipment box to ensure sufficient ventilation area. The edge of the vent protrudes upward to form a rainproof edge. The height and width of the rainproof edge have been optimized through rainproof testing to effectively prevent rainwater from falling vertically or splashing obliquely into the box. The dustproof mesh is made of high-density stainless steel wire mesh, which can block dust, insects and other foreign objects from entering without affecting air circulation. The dustproof mesh is connected to the inner wall of the vent with buckles, which is convenient for regular disassembly and cleaning to prevent the mesh from becoming clogged and affecting heat dissipation. At the same time, a removable activated carbon filter is installed inside the vent. The activated carbon filter is located below the dustproof mesh and can absorb moisture and harmful gases in the air to protect the power equipment inside the box from corrosion.

[0039] Specifically, during the operation of the power equipment box 1, the air inside the box becomes less dense after being heated, and will naturally flow upwards and be discharged outside the box through the heat dissipation vent at the top. At the same time, cooler air from outside enters from other ventilation parts inside the box, such as heat dissipation windows 71, forming natural convection to assist in heat dissipation. During the air circulation process, the dustproof net intercepts dust and impurities in the air, preventing them from entering the box and adhering to the surface of the power equipment, thus affecting the heat dissipation and insulation performance of the equipment. This structure solves the problems of poor natural heat dissipation effect and easy entry of external dust into the box in the background technology. It enhances natural convection heat dissipation through the heat dissipation vent at the top, and achieves dust prevention function in conjunction with the dustproof net, thereby improving the heat dissipation effect and internal cleanliness of the power equipment box.

[0040] Furthermore, the water pump 53, solenoid valve 511, temperature sensor 63 and drive device 75 are all electrically connected to the controller 61, and the controller 61 is electrically connected to an external power supply.

[0041] It should be noted that the water pump 53, solenoid valve 511, temperature sensor 63, and drive device 75 described in this embodiment are all connected to the controller 61 using shielded cables with grounded shielding to prevent external electromagnetic interference from affecting signal transmission and equipment operation. The cables are fixed inside the power equipment box 1 by cable trays to prevent messy cables from affecting other components or being damaged by sharp objects. The controller 61 integrates overcurrent, overvoltage, and short-circuit protection modules. When abnormal current or voltage occurs in components such as the water pump 53 and drive device 75, the controller 61 can quickly cut off the power supply to protect the equipment. The controller 61 is connected to the external power supply through an air switch with leakage protection to further improve electrical safety. At the same time, the controller 61 has a low-power mode, which automatically switches to low-power mode when the equipment is operating under low load and the heat dissipation requirement is low, reducing overall energy consumption.

[0042] Specifically, the external power supply powers the controller 61 via an air switch. The controller 61 receives water temperature detection signals from the temperature sensor 63 in real time, analyzes and processes the signals, and when it determines that water circulation cooling needs to be activated, the controller 61 sends control signals to the water pump 53 and the solenoid valve 511 to start them. When it determines that auxiliary cooling needs to be activated, the controller 61 sends control signals to the drive device 75 and the cooling fan 73 to control the opening of the cooling window 71 and the activation of the cooling fan 73. When the water temperature or the temperature inside the tank is detected to drop to a safe range, the controller 61 sends a stop signal to shut down the corresponding components. This structure solves the problems of independent operation of each component in the heat dissipation system, lack of coordinated control, and low level of intelligence in the prior art. The controller 61 enables centralized management and coordinated operation of each heat dissipation component, improves the intelligence level and operational reliability of the heat dissipation system, and ensures that the power equipment box is always in a suitable temperature environment.

[0043] In summary, the metal column 2 absorbs heat from the core components inside the box through its aluminum alloy material and external heat sink 21. Some of the heat is absorbed by the internal cold water. The temperature sensor 63 transmits the water temperature data to the controller 61. When the water temperature reaches the threshold, the controller 61 activates the connecting component 5. The water pump 53 sends the warm water through the pipe to the water-cooled radiator 8 for cooling and then back to the container, forming a water circulation cooling system. If the cooling is insufficient, the controller 61 activates the auxiliary component 7. The drive device 75 drives the sealing plate 72 to open the heat dissipation window 71, and the cooling fan 73 accelerates the air circulation. The top heat dissipation vent assists in natural convection. After the temperature drops to a safe value, all components are shut down under the control of the controller 61. This solves the problems of insufficient heat dissipation efficiency, inability to cope with sudden high heat loads, and easy heat accumulation caused by a single heat dissipation method for medium and high power equipment. At the same time, the dustproof net and sealing strip structure also provide dustproof and waterproof protection, meeting the requirements for long-term stable operation of the equipment.

[0044] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. 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.
