[0011] In one possible implementation, the housing is provided with a heat dissipation fin assembly, at least a portion of which is located inside the housing and at least a portion of which is located outside the housing.

[0012] In one possible implementation, the air guide assembly includes a first air guide element, which is disposed inside the housing and spaced apart from the heat dissipation fin assembly.

[0013] The first air guide extends in the same direction as the heat dissipation fin assembly, and the first air guide is an arc shape that protrudes towards the heat dissipation fin assembly in the middle, with one end of the first air guide extending towards the blower.

[0014] In one possible implementation, the air guide assembly further includes a wave-shaped second air guide connected to the heat dissipation fin group, and the second air guide is located between the first air guide and the heat dissipation fin group. The gap between the first air guide and the second air guide forms an acceleration channel for increasing the flow rate of the airflow.

[0015] In one possible implementation, the liquid cooling assembly includes:

[0016] A liquid storage tank, which is used to hold coolant;

[0017] A liquid cooling pipe, both ends of which are connected to the liquid storage tank, wherein the liquid cooling pipe is at least partially used to contact the electronic device;

[0018] A circulation pump is used to circulate the coolant into the liquid cooling pipe.

[0019] In one possible implementation, the liquid cooling assembly further includes a flow divider and an air duct, the flow divider having a flow divider channel, one end of the flow divider channel extending in the direction of extension facing the air blower, and the other end of the flow divider channel extending in the direction of extension communicating with the liquid storage tank through the air duct.

[0020] In one possible implementation, the liquid storage tank is provided with an aeration element, the aeration element is hollow inside, the aeration element has a plurality of air outlets that connect its interior to the outside, and the air outlets are immersed in the coolant.

[0021] The two ends of the air duct are respectively connected to the flow divider and the aeration element.

[0023] In one possible implementation, the system further includes a control unit and at least one sensor electrically connected to the control unit. The sensor is used to detect the temperature and / or humidity inside the housing.

Thus, during use, airflow is blown into the shell by the blower, and the airflow velocity within the shell is increased by the guide assembly, resulting in better heat dissipation efficiency for the electronic components. Simultaneously, the liquid cooling assembly further dissipates heat from the electronic components, thereby significantly improving the heat dissipation effect of the electrical equipment during use, reducing the possibility of heat accumulation inside the equipment, extending its service life, and solving the problem of poor heat dissipation in existing electrical equipment.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0040] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0041] In related technologies, power equipment includes a housing and electronic components. The housing includes a shell with a fan, and the electronic components are installed inside the shell. During use, the fan blows air into the shell to dissipate heat from the electronic components.

[0042] However, relying solely on fans to dissipate heat from electronic components is ineffective, which can lead to heat buildup inside electrical equipment and accelerate the aging of some materials within the equipment.

[0043] Therefore, this application provides a housing structure and electrical equipment. The housing structure includes: a shell, the interior of which houses electronic components; a blower, disposed on the shell, used to blow airflow into the shell to dissipate heat from the electronic components; a guide assembly, disposed inside the shell, used to guide the airflow and increase its velocity; and a liquid cooling assembly, disposed on the shell, used to dissipate heat from the electronic components. Thus, during use, airflow is blown into the shell by the blower, and the airflow velocity within the shell is increased by the guide assembly, resulting in better heat dissipation efficiency for the electronic components. Simultaneously, the liquid cooling assembly further dissipates heat from the electronic components, thereby significantly improving the heat dissipation effect of the electrical equipment during use, reducing the possibility of heat accumulation inside the equipment, extending its service life, and solving the problem of poor heat dissipation in existing electrical equipment.

[0044] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0045] like Figure 1 and Figure 2 As shown in the figure, an embodiment of this application provides a box structure, including:

[0046] Housing 100, the interior of housing 100 is used to house electronic components;

[0047] A blower 200 is disposed on the housing 100 and is used to blow airflow into the interior of the housing 100 to dissipate heat from electronic components.

[0048] An air guide assembly 300 is disposed inside the housing 100. The air guide assembly 300 is used to guide airflow to increase the airflow velocity.

[0049] Liquid cooling component 400 is disposed on housing 100 and is used to dissipate heat from electronic components.

[0050] The housing 100 has a hollow internal structure, allowing electronic components to be installed inside. Furthermore, the housing 100 can be configured with an open end, facilitating the insertion of electronic components through this opening. In this embodiment, the housing 100 has an open top, and a cover 110 is provided on it. The cover 110 covers the opening in the housing 100 to seal it, ensuring the safety of the electronic components inside. The cover 110 can be connected to the housing 100 by screws, pins, snaps, or other means, without limitation.

[0051] The blower 200 is a fan, and the fan model is not limited. Specifically, a fan cover 210 can be fixed to the side of the housing 100 by screwing, welding, or other means, and the fan cover 210 is located outside the housing 100, with the interior of the fan cover 210 connected to the interior of the housing 100. The blower 200 is then installed inside the fan cover 210 by screwing, snapping, or other means, so that when the blower 200 is in operation, airflow can be blown into the housing 100 to dissipate heat from the electronic components.

[0052] Secondly, the air guide assembly 300 is disposed inside the housing 100 to guide the airflow blown into the housing 100, thereby increasing the airflow velocity.

[0053] It should be noted that the housing 100 is also provided with ventilation openings. In this embodiment, the ventilation openings and the fan shroud 210 are respectively distributed on the opposite side walls of the housing 100. Of course, the ventilation openings can also be set in other parts of the housing 100, and there is no limitation on this, as long as the airflow carrying heat inside the housing 100 can be discharged to the outside through the ventilation openings.

[0054] In use, airflow can be blown into the housing 100 through the blower 200. Secondly, under the guidance of the air guide assembly 300, the airflow velocity inside the housing 100 can be increased, resulting in better heat dissipation efficiency for electronic devices. At the same time, the liquid cooling assembly 400 further dissipates heat from the electronic devices, thereby greatly improving the heat dissipation effect of the power equipment during use, reducing the possibility of heat accumulation inside the power equipment, extending the service life of the power equipment, and solving the problem of poor heat dissipation effect of power equipment in the prior art.

[0055] It should be noted that, for example Figure 3 As shown, the cover 110 can be a double-layer hollow structure, with the hollow interior filled with aerogel insulation material to form an insulation layer 111. This effectively blocks external heat from entering the housing 100 from the cover 110, reducing the heat dissipation burden. Furthermore, drainage grooves can be provided at the edge of the cover 110 to effectively drain rainwater and reduce the possibility of water accumulation on the upper surface of the cover 110.

[0056] In some embodiments, such as Figure 1 As shown, motorized louvers 500 can be installed on the housing 100 at the locations corresponding to the ventilation opening and the fan cover 210. One motorized louver 500 covers the ventilation opening; the other motorized louver 500 covers the end of the fan cover 210 facing the housing 100, and the blower 200 is located on the side of the motorized louver 500 away from the housing 100.

[0057] Therefore, during use, the opening and closing of the vent or the fan cover 210, as well as the size of the opening, can be controlled by the electric louver 500, which facilitates the control of the airflow blown into the housing 100 and optimizes the control of the heat dissipation efficiency of the power equipment.

[0058] In practice, the motorized louver 500 can be connected to the housing 100 by screwing, snapping, gluing or other means, and there are no restrictions on this.

[0059] In addition, such as Figure 2 As shown, a protective net 211 can also be covered at the end of the shroud 210 away from the housing 100 to cover the air inlet end of the blower 200. This reduces the possibility of external debris (such as insects, paper scraps, leaves, etc.) entering the housing 100 with the airflow during the operation of the blower 200, ensuring the safe use of the electrical equipment.

[0060] In implementation, the protective net 211 can be fixed to the wind cover 210 by magnetic attraction, screwing, fastening, or other means, and there are no restrictions on this. Preferably, the mesh size of the protective net 211 can be 0.5~1mm.

[0061] In some embodiments, such as Figure 2 As shown, a heat dissipation fin assembly 600 is provided on the housing 100, with at least a portion of the heat dissipation fin assembly 600 located inside the housing 100 and at least a portion located outside the housing 100.

[0062] In this embodiment, two heat dissipation fin assemblies 600 are provided on the housing 100, and the two heat dissipation fin assemblies 600 are respectively located on the other opposite side walls of the housing 100; of course, the number of heat dissipation fin assemblies 600 can also be set to other quantities. In implementation, an installation port can be opened on the side of the housing 100, and then the heat dissipation fin assembly 600 can be fixed in the installation port, so that one end of the heat dissipation fin assembly 600 faces the inside of the housing 100, and the other end is located on the outside of the housing 100.

[0063] The heat dissipation fin assembly 600 includes multiple heat dissipation fins 610, which can be made of copper, aluminum, or other materials with excellent thermal conductivity. One end of each heat dissipation fin 610 is connected to the other, while the other ends are spaced apart. In practice, each heat dissipation fin 610 can be integrally formed, or one end of the heat dissipation fins 610 can be connected to the other by welding or other methods. The connected ends of each heat dissipation fin 610 face inwards towards the housing 100.

[0064] Therefore, during use, the heat inside the housing 100 can be transferred to the outside through the heat dissipation fin assembly 600, further improving the heat dissipation efficiency of the power equipment.

[0065] In some embodiments, such as Figure 2 As shown, the air guide assembly 300 includes a first air guide 310, which is disposed inside the housing 100 and spaced apart from the heat dissipation fin assembly 600.

[0066] The extension direction of the first air guide 310 is consistent with the extension direction of the heat dissipation fin group 600, and the first air guide 310 is an arc shape that protrudes from the middle towards the heat dissipation fin group 600, with one end of the first air guide 310 extending towards the blower 200.

[0067] In this embodiment, the first air guide 310 is disposed inside the housing 100. Two first air guides 310 correspond to two heat dissipation fin groups 600, with each first air guide 310 corresponding to one of the two heat dissipation fin groups 600. The first air guides 310 and the heat dissipation fin groups 600 are spaced apart. The first air guide 310 can be an arc-shaped plate, and its material is not limited. The extending direction of the first air guide 310 is consistent with the extending direction of the heat dissipation fin group 600, and the first air guide 310 has an arc shape that bulges towards the heat dissipation fin group 600 in the middle. One end of the extending direction of the first air guide 310 faces the blower 200.

[0068] During the operation of the blower 200, when the airflow blows towards the arc-shaped sidewall of the first air guide 310 facing the heat dissipation fin assembly 600, the flow rate of the airflow will increase due to the Venturi effect, thereby assisting in the heat dissipation of the heat dissipation fin assembly 600 and optimizing the heat dissipation effect of the heat dissipation fin assembly 600 on the power equipment.

[0069] In other embodiments, the first air guide 310 may also be of other shapes.

[0070] When implementing, such as Figure 2 As shown, the first air guide 310 can be supported by multiple support columns 311. Specifically, one end of the support column 311 is fixed to the inner wall of the housing 100 by screwing, welding or other means, and then the first air guide 310 is fixed to the other end of the support column 311 by screwing, snapping or other means, thereby completing the installation of the first air guide 310.

[0071] Furthermore, such as Figure 2 As shown, the air guide assembly 300 also includes a wave-shaped second air guide 320, which is connected to the heat dissipation fin group 600 and is located between the first air guide 310 and the heat dissipation fin group 600. The gap between the first air guide 310 and the second air guide 320 forms an acceleration channel 330 for increasing the airflow velocity.

[0072] In this embodiment, the number of the second air guide 320 is set to correspond to the number of the first air guide 310, that is, there are two second air guides 320, and the two second air guides 320 correspond one-to-one with the two first air guides 310.

[0073] Secondly, the second air guide 320 can be a corrugated plate. The extension direction of the second air guide 320 is consistent with the extension direction of the first air guide 310. The second air guide 320 is attached to the surface of the heat dissipation fin assembly 600 facing the inside of the housing 100, so that the second air guide 320 is located between the first air guide 310 and the heat dissipation fin assembly 600, and the gap between the first air guide 310 and the second air guide 320 forms an acceleration channel 330 for increasing the flow rate of the airflow.

[0074] As a result, some airflow can enter the acceleration channel 330 between the first air guide 310 and the second air guide 320, and the airflow entering the acceleration channel 330 alternately contracts and expands, optimizing the acceleration effect of the airflow. This can increase the airflow velocity by 20% to 30%, enhance the heat exchange between the airflow inside the housing 100 and the heat dissipation fin assembly 600, further improve the heat dissipation effect of the heat dissipation fin assembly 600, and effectively enhance the heat dissipation capacity of the heat dissipation fin assembly 600 for power equipment.

[0075] In implementation, the material of the second air guide 320 is not limited, but a metal material with good thermal conductivity is preferred. The second air guide 320 can be connected to the heat dissipation fin assembly 600 by welding, bonding, screwing or other means; of course, the second air guide 320 can also be fixed to the housing 100, so that the second air guide 320 is in contact with the heat dissipation fin assembly 600.

[0076] In addition, such as Figure 2 As shown, multiple support ribs 340 can be added between the first air guide 310 and the second air guide 320. The two ends of the support ribs 340 are connected to the first air guide 310 and the second air guide 320 by screwing, bonding, snapping, or other means. In this way, the support ribs 340 improve the stability of the first air guide 310 and the second air guide 320 during use and reduce the possibility of vibration deformation.

[0077] In some embodiments, such as Figure 1 and Figure 2 As shown, the liquid cooling assembly 400 includes:

[0078] The liquid storage tank 410 is used to hold coolant.

[0079] Liquid cooling pipe 420, both ends of which are connected to liquid storage tank 410, and liquid cooling pipe 420 is at least partially used for contact with electronic devices;

[0080] The circulation pump 430 is used to circulate the coolant into the liquid cooling pipe 420.

[0081] The liquid storage tank 410 is installed outside the housing 100. The liquid storage tank 410 can be connected to the housing 100 via a bracket. The liquid storage tank 410 contains coolant, which can be water, refrigerant or other liquid.

[0082] One end of the liquid cooling pipe 420 is connected to the lower part or bottom of the liquid storage tank 410, and the other end of the liquid cooling pipe 420 passes through the housing 100, extending in a spiral trajectory within the housing 100 before reconnecting to the liquid storage tank 410. A circulation pump 430 is installed on the liquid cooling pipe 420 to circulate the coolant in the liquid storage tank 410 into the liquid cooling pipe 420. The circulation pump 430 can be a centrifugal pump, a reciprocating pump, or other types, and there are no restrictions on this.

[0083] It should be noted that the portion of the liquid cooling pipe 420 located inside the housing 100 extends in a spiral trajectory, and this portion of the liquid cooling pipe 420 is located on the outer periphery of the electronic device, and the liquid cooling pipe 420 is in contact with the electronic device.

[0084] In use, the circulating pump 430 pumps the coolant in the storage tank 410 into the liquid cooling pipe 420, and then the liquid cooling pipe 420 effectively dissipates heat from the electronic components, improving the heat dissipation efficiency of the power equipment.

[0085] In a preferred embodiment, the portion of the liquid cooling pipe 420 located inside the housing 100 is disposed on the side of the first air guide 310 away from the heat dissipation fin assembly 600, so that part of the airflow blown out by the air blower 200 will be blown toward the liquid cooling pipe 420 and the electronic device, thereby dissipating heat on the electronic device and the liquid cooling pipe 420 at the same time.

[0086] In addition, the volume of the liquid storage tank 410 can be set to 1.2 to 1.5 times the total volume of the liquid cooling pipe 420 to ensure sufficient heat storage capacity of the coolant.

[0087] Understandably, the coolant flowing back into the reservoir 410 often carries heat. After prolonged use, if the heat of the coolant in the reservoir 410 is not dissipated in time, the coolant carrying a large amount of heat can easily re-enter the liquid cooling pipe 420, thereby reducing the subsequent heat dissipation effect on electronic components.

[0088] Therefore, in some embodiments, such as Figure 4 As shown, the liquid cooling assembly 400 also includes a flow divider 440 and an air duct 450. The flow divider 440 has a flow divider channel 441. One end of the flow divider channel 441 extends toward the air blower 200, and the other end of the flow divider channel 441 extends through the air duct 450 and is connected to the liquid storage tank 410.

[0089] Specifically, the diverter 440 can be a conical cylindrical structure, making the interior of the diverter 440 hollow, so as to form a conical diverting channel 441 (i.e., having a large end and a small end) inside the diverter 440. In this case, the diverter 440 is disposed inside the housing 100, and the large end of the diverter 440 faces the blower 200; the small end of the diverter 440 is connected to the liquid storage tank 410 through the air guide pipe 450. Preferably, the end of the air guide pipe 450 facing the liquid storage tank 410 extends into the coolant. At this time, an air outlet can also be added to the liquid storage tank 410, and the air outlet is located above the liquid surface of the coolant.

[0090] When the blower 200 blows air into the housing 100 to dissipate heat from the electronic components, some of the airflow also enters the distribution channel 441 and flows into the coolant tank 410 through the air duct 450. This generates air bubbles in the coolant, which then carry away heat, achieving the purpose of cooling the coolant. The air outlet ensures good ventilation within the coolant tank 410, expelling the hot airflow and improving the coolant's cooling effect. This timely removal of heat from the coolant ensures that when the coolant subsequently circulates into the liquid cooling pipe 420, it also provides good heat dissipation for the electronic components.

[0091] In other embodiments, the diverter 440 may also be configured as a tube or other shape, as long as it has the function of diverting airflow.

[0092] Furthermore, such as Figure 4 As shown, the flow divider 440 is provided with a flow guide 442, which is located inside the flow divider channel 441. The flow guide 442 is used to increase the flow velocity of the airflow inside the flow divider channel 441.

[0093] It should be noted that the flow guide 442 can be multiple flow guide vanes, which can be fixed inside the flow divider 440 by a bracket, and the flow guide vanes are correspondingly set at the large end of the flow divider channel 441. When the airflow enters the flow divider channel 441, the airflow will be accelerated under the guidance of the conical flow divider channel 441 and the flow guide vanes, so that the airflow has a greater impact force when it enters the liquid storage tank 410, thereby generating bubbles more stably in the coolant.

[0094] In other embodiments, the guide member 442 may also be a guide portion disposed on the inner wall of the diverter 440, or a guide groove formed on the inner wall of the diverter 440.

[0095] Furthermore, such as Figure 4 As shown, the liquid storage tank 410 is equipped with an aeration element 460. The aeration element 460 is hollow inside and has multiple air outlets that connect its interior to the outside. The air outlets are immersed in the coolant.

[0096] The two ends of the air duct 450 are connected to the diversion component 440 and the aeration component 460, respectively.

[0097] The aeration element 460 can be a hollow box-shaped structure, and can be installed at the lower part of the liquid storage tank 410 by screwing, mounting, or other means. The aeration element 460 has multiple air outlets that connect its interior to the exterior, and these outlets are submerged in the coolant. Preferably, the multiple air outlets are evenly distributed on the top wall of the aeration element 460.

[0098] The two ends of the air duct 450 can be connected to the small end of the diverter 440 and the aeration element 460 respectively by welding, plugging, screwing or other means, so as to make the diverter channel 441, the interior of the air duct 450 and the interior of the aeration element 460 interconnected.

[0099] During use, the airflow enters the aeration element 460 under the action of the air guide 450, and then the airflow is output from each air outlet, which makes the bubbles more dispersed and evenly generated in the coolant, thus improving the heat dissipation effect of the coolant and increasing the heat dissipation efficiency.

[0100] In practice, to reduce the possibility of coolant entering the aeration element 460 from the vent, for example, a miniature one-way valve can be installed in each vent to limit coolant from entering the aeration element 460.

[0101] In some embodiments, such as Figure 2 As shown, the housing structure also includes a control unit 700 and at least one sensor. The sensor is electrically connected to the control unit 700 and is used to detect the temperature and / or humidity inside the housing. When the temperature and / or humidity reach a preset value, the control unit 700 controls the operation of the blower 200 and / or the liquid cooling assembly 400.

[0102] In this embodiment, as Figure 2 As shown, multiple sensors are provided, including multiple temperature sensors 710 and humidity sensors 720, and each sensor is electrically connected to the control unit 700. The temperature sensors 710 and humidity sensors 720 can be fixed to the inner wall of the housing 100 by screwing, bonding or other means.

[0103] Therefore, the temperature inside the housing 100 can be detected by the temperature sensor 710, and the humidity inside the housing 100 can be detected by the humidity sensor 720. When the temperature and / or humidity reach the preset value, the circulation pump 430 in the motorized louver 500, the blower 200, and / or the liquid cooling assembly 400 is controlled to operate by the control unit 700.

[0104] Preferably, the temperature sensors 710 can be distributed around the electronic components, and the humidity sensors 720 can be distributed near the motorized blinds 500.

[0105] For example, the control unit 700 has a built-in PID control algorithm that dynamically adjusts the flow rate of the circulating pump 430, the rotation speed of the blower 200, and the opening and closing of the electric louvers 500 based on the data collected by the temperature sensor 710 and the humidity sensor 720.

[0106] The control formula for the PID control algorithm is as follows:

[0107]

[0108] In the formula, U(t) is the control quantity, i.e., the flow rate of the circulating pump 430 or the rotational speed of the blower 200; e(t) is the deviation between the set value and the actual measured value of temperature or humidity; e(T) is the difference between the set value and the actual measured value at any time; dT is the increment of time T, which infinitely approaches 0; K p K is a proportional coefficient; for the flow rate control of circulating pump 430, K p Setting it to 2, for the speed control of the blower 200, K p Set to 1.5; K i K is the integral coefficient; the integral coefficient for temperature control is set to 0.1, and the integral coefficient for humidity control is set to 0.05. d The differential coefficient is set to 0.5. The deviation value e(t) represents the rate of change of time t, i.e., the amount of change of deviation per unit time, reflecting the rate of temperature rise and the rate of humidity change.

[0109] An example temperature control strategy:

[0110] When the temperature sensor 710 detects a temperature T≤50℃, the control unit 700 adjusts the circulating pump 430 to run at a first flow rate of 2L / min, the blower 200 to run at a first speed of 800r / min, and the electric louver 500 to maintain a 30% opening to maintain basic heat dissipation requirements according to the PID algorithm.

[0111] When the temperature sensor 710 detects a temperature of 50℃ < T ≤ 70℃, the control unit 700 adjusts the circulating pump 430 to run at a second flow rate of 4L / min, the blower 200 to run at a second speed of 1200r / min, and the opening of the electric louver 500 to 60% to enhance the heat dissipation effect.

[0112] When the temperature sensor 710 detects a temperature of 70℃ < T, the control unit 700 adjusts the circulating pump 430 to run at the third flow rate of 6L / min according to the PID algorithm, the blower 200 to run at the third speed of 1600r / min, and the opening of the electric louver 500 to 100%, so as to cool down the electrical equipment quickly.

[0113] Humidity control strategy:

[0114] When the humidity sensor 720 detects that the ambient humidity H ≤ 60%, the motorized louver 500 will adjust its opening degree normally according to the above temperature control strategy.

[0115] When the ambient humidity is 60% < H, the control unit 700 controls the motorized louvers 500 to close, reducing the possibility of external humid air entering the housing 100 and affecting the normal operation of electronic devices. At the same time, it increases the flow rate of the circulation pump 430 to enhance the liquid cooling effect.

[0116] In summary, the housing structure provided in this application embodiment allows airflow to be blown into the housing 100 via the blower 200 during use. Furthermore, the airflow velocity within the housing 100 is increased under the guidance of the air guide assembly 300, resulting in better heat dissipation efficiency for electronic components. Simultaneously, the liquid cooling assembly 400 further dissipates heat from the electronic components, thereby significantly improving the heat dissipation effect of the power equipment during use, reducing the possibility of heat accumulation inside the power equipment, extending the service life of the power equipment, and solving the problem of poor heat dissipation in existing power equipment.

[0117] This application also provides an electrical device, which may be a transformer, circuit breaker, or switch, etc. The electrical device includes electronic components and the enclosure structure as described in any of the above embodiments, with the electronic components located within the housing 100 of the enclosure structure.

[0118] The box structure has been described in detail in the above embodiments and will not be repeated here.

[0119] Electronic components can be installed inside the housing 100 within the enclosure structure via screwing, bonding, or other methods. Liquid cooling pipes 420 within the enclosure structure are distributed around the electronic components and are in contact with them. The electronic components can be, for example, iron cores, windings, or other parts; there are no restrictions on this.

[0120] Therefore, during the operation of the electronic device, airflow can be blown into the housing 100 through the blower 200. Secondly, under the guidance of the air guide assembly 300, the airflow velocity inside the housing 100 is increased, resulting in better heat dissipation efficiency for the electronic device. At the same time, the liquid cooling assembly 400 further dissipates heat from the electronic device, thereby greatly improving the heat dissipation effect of the power equipment during use, reducing the possibility of heat accumulation inside the power equipment, extending the service life of the power equipment, and solving the problem of poor heat dissipation effect of power equipment in the prior art.
