Description

Technical Field

[0001] This invention relates to the field of power equipment technology, specifically a wall-mounted intelligent power distribution control box. Background Technology

[0002] A power distribution control box is a device that assembles switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system. During normal operation, circuits can be connected or disconnected manually or automatically. In case of faults or abnormal operation, circuits are cut off or alarms are triggered by protective electrical appliances. Power distribution control boxes are mainly classified into ground-mounted, wall-mounted, and column-mounted types according to their installation method. The power distribution control box contains numerous electrical components, and prolonged operation can lead to excessively high internal temperatures. To prevent damage from prolonged exposure to high temperatures, a heat dissipation mechanism needs to be installed inside the box. Traditional heat dissipation designs typically involve installing a fan and air inlets on the control box, forming a bottom-in, top-out or side-in, side-out cooling duct.

[0003] Patent CN222637984U discloses a heat dissipation power distribution cabinet, including a cabinet body and an air intake box installed on one side of the cabinet body. An exhaust box is installed on the other side of the cabinet body. A cabinet door is rotatably installed on the front of the cabinet body. A filter mechanism is installed inside the air intake box. Multiple first fans are installed through the top of the air intake box, and multiple evenly distributed second fans are installed through the bottom of the exhaust box. Multiple evenly distributed support legs are installed at the bottom of the cabinet body. Multiple air intake holes and exhaust holes are respectively opened on the side walls of the cabinet body, cooperating with the air intake box and the exhaust box. It constructs a heat dissipation airflow channel inside the cabinet body through the fans, achieving heat dissipation inside the cabinet body.

[0004] As disclosed in the above-mentioned patent, a fan is installed on one side of the cabinet and an exhaust box is installed on the other side to form a side-inlet and side-outlet heat dissipation air duct. However, the airflow follows the principle of least resistance and will choose the flow path with the least resistance when flowing. Traditional direct blowing of fans often creates a shortcut in the air duct inside the control box, which prevents the airflow from flowing to all parts of the box and creates heat dissipation dead zones, resulting in heat accumulation in some areas. Therefore, a wall-mounted intelligent power distribution control box is urgently needed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a wall-mounted intelligent power distribution control box to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wall-mounted intelligent power distribution control box, comprising a control box housing and an electric fan disposed on the top of the control box housing, a dustproof net at the bottom, and a flow guide grille mechanism disposed at the air inlet of the electric fan for changing the direction of the airflow drawn by the electric fan; a temperature regulating component for operating according to temperature changes and adjusting the flow guide grille mechanism; and a heat pipe heat conduction mechanism for conducting heat.

[0007] The flow guide grille mechanism is rotatably configured as a whole, including a lower flow guide grille group and an upper flow guide grille group;

[0008] The heat pipe heat conduction mechanism transfers heat from the high-heat location to the temperature change regulating component. The temperature change regulating component then operates according to temperature changes, driving the flow guide grille mechanism to rotate back and forth, and driving the lower and upper flow guide grille groups to adjust their tilt angles, thereby changing the flow direction of the airflow inside the control box housing when the electric fan is drawing air.

[0009] Preferably, the control box housing contains several electrical components, and the heat pipe heat conduction mechanism is installed at the location of the high-heat electrical components.

[0010] Preferably, the heat pipe heat conduction mechanism includes a heat absorption plate installed on the back of the high-heat electrical component; and a diffuser head disposed outside the temperature regulation component. After the heat absorption plate absorbs the heat emitted by the high-heat electrical component, it can conduct the heat to the diffuser head.

[0011] Preferably, the flow guide grille mechanism includes a rotatable mounting frame, in which an upper flow guide grille group and a lower flow guide grille group are arranged in two layers and arranged in a longitudinal and transverse manner. The upper flow guide grille group and the lower flow guide grille group can be driven to adjust their tilt angle.

[0012] Preferably, the temperature regulating component includes an upper tilt angle adjusting mechanism, which is linked with the upper guide grille group and drives the upper guide grille group to move when the temperature changes; a lower tilt angle adjusting mechanism, which is linked with the lower guide grille group and drives the lower guide grille group to move when the temperature changes; and a reciprocating rotation mechanism, which is linked with the mounting frame and drives the mounting frame to reciprocate when the temperature changes.

[0013] Preferably, the tilt adjustment mechanism includes a memory metal spring and a spiral sleeve. A spiral rod is spirally connected to the spiral sleeve. When the memory metal spring expands due to heat, it can drive the spiral sleeve to move and drive the spiral rod to rotate.

[0014] Preferably, the upward tilt adjustment mechanism further includes a transmission worm gear, which is fixedly connected to the helical rod; and a transmission worm wheel, which is connected to the upper guide grille assembly, and the transmission worm wheel and the transmission worm gear mesh with each other.

[0015] Preferably, the difference between the downward tilt adjustment mechanism and the upward tilt adjustment mechanism is that the downward tilt adjustment mechanism further includes a transmission gear, and is connected to the lower guide grille assembly through the transmission gear.

[0016] Preferably, the reciprocating rotation mechanism differs from the tilt adjustment mechanism in that the reciprocating rotation mechanism further includes a drive gear and an arc-shaped rack, and the drive gear and the arc-shaped rack mesh with each other.

[0017] Preferably, when the reciprocating rotation mechanism is heated, it can move to the outside of the heat pipe heat conduction mechanism through the drive gear and the arc rack, and return to the inside of the heat pipe heat conduction mechanism after cooling down outside the heat pipe heat conduction mechanism.

[0018] In the above technical solution, the beneficial effects of the present invention are as follows: a guide grille mechanism is set at the air inlet of the electric fan, and the heat from the high-heat electrical components is conducted to the temperature-changing regulating component through the heat pipe heat conduction mechanism. The temperature-changing regulating component can drive the guide grille mechanism to rotate back and forth according to the temperature change, and at the same time drive the lower guide grille group and the upper guide grille group to adjust the tilt angle, thereby changing the direction of the airflow drawn by the electric fan and creating turbulence inside the control box housing. The turbulence can effectively disrupt the inherent laminar flow, allowing the airflow to flow through all parts of the control box housing, and effectively avoiding the existence of heat dissipation dead zones.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0036] Please see Figure 1-11 This invention provides a technical solution: a wall-mounted intelligent power distribution control box, including a control box housing 1 and an electric fan 7 disposed on the top of the control box housing 1, a dustproof net 6 at the bottom, and a flow guide grille mechanism 9 disposed at the air inlet of the electric fan 7 to change the direction of the airflow drawn by the electric fan 7; a temperature adjustment component for adjusting the flow guide grille mechanism 9 according to temperature changes; and a heat pipe heat conduction mechanism 8 for conducting heat.

[0037] The flow guide grille mechanism 9 is rotated as a whole, including a lower flow guide grille group 94 and an upper flow guide grille group 95;

[0038] After the heat pipe heat conduction mechanism 8 conducts the heat from the high-heat location to the temperature change regulating component, the temperature change regulating component acts according to the temperature change, drives the flow guide grille mechanism 9 to reciprocate, and drives the lower flow guide grille group 94 and the upper flow guide grille group 95 to adjust the tilt angle, thereby changing the flow direction of the airflow inside the control box housing 1 when the electric fan 7 is sucking.

[0039] The control box housing 1 has a hinged door 2 on the front for sealing and protecting the control box housing 1; a connecting busbar 5 is provided in the control box housing 1, and the electrical components 4 in the control box housing 1 are electrically connected through the connecting busbar 5; the control box housing 1 is also provided with a mounting bracket 3, and the electrical components 4 are fixedly installed inside the control box housing 1 through the mounting bracket 3.

[0040] Specifically, the electric fan 7, controlled by the control system, draws in the high-temperature gas inside the control box housing 1 and draws in cool air along the dustproof mesh 6, forming a bottom-in, top-out heat dissipation airflow channel inside the control box housing 1 to dissipate heat from several electrical components 4 inside the control box housing 1. The heat pipe heat conduction mechanism 8 is installed on the back of the high-heat-generating electrical components 4, absorbing the heat dissipated by the high-heat-generating electrical components 4 and conducting it to the position of the temperature-regulating component. The reciprocating rotation mechanism 12 in the temperature-regulating component is heated in the corresponding position of the heat pipe heat conduction mechanism 8, driving the mounting frame 93 to rotate as a whole. Simultaneously, as the mounting frame 93 rotates, it drives the reciprocating rotation mechanism 12 to move synchronously to the outside of the corresponding position of the heat pipe heat conduction mechanism 8. After the reciprocating rotation mechanism 12 moves to the outside of the heat pipe heat conduction mechanism 8, the temperature decreases, causing the reciprocating rotation mechanism 12 to reset and drive the mounting frame 93 to rotate in the opposite direction. This cycle continues, driving the mounting frame 93 to rotate. The frame 93 rotates back and forth as a whole. When the upper tilt angle adjustment mechanism 10 and the lower tilt angle adjustment mechanism 11 in the temperature-changing adjustment component are located in the heat pipe heat conduction mechanism 8 at the corresponding positions, the upper tilt angle adjustment mechanism 10 and the lower tilt angle adjustment mechanism 11 are heated and drive the lower guide grid group 94 and the upper guide grid group 95, so that the tilt angle of the lower guide grid group 94 and the upper guide grid group 95 is adjusted to one side. Driven by the mounting frame 93, the upper tilt angle adjustment mechanism 10 and the lower tilt angle adjustment mechanism 11 move to the outside of the heat pipe heat conduction mechanism 8 at the corresponding positions. The temperature of the upper tilt angle adjustment mechanism 10 and the lower tilt angle adjustment mechanism 11 decreases. The upper tilt angle adjustment mechanism 10 and the lower tilt angle adjustment mechanism 11 reset and drive the tilt angle of the lower guide grid group 94 and the upper guide grid group 95 to adjust to the other side. By frequently changing the tilt angle of the lower guide grid group 94 and the upper guide grid group 95, the direction of air intake of the electric fan 7 is frequently changed, so that turbulence is formed inside the control box housing 1, avoiding the existence of heat dissipation dead zones.

[0041] Compared with the prior art, the present invention sets a flow guide grille mechanism 9 at the air inlet of the electric fan 7, and conducts the heat from the high-heat electrical component 4 to the temperature adjustment component through the heat pipe heat conduction mechanism 8. The temperature adjustment component can drive the flow guide grille mechanism 9 to rotate back and forth according to the temperature change, and at the same time drive the lower flow guide grille group 94 and the upper flow guide grille group 95 to adjust the tilt angle, change the direction of the airflow drawn by the electric fan 7, and create turbulence inside the control box housing 1. The turbulence can effectively disrupt the inherent laminar flow, allowing the airflow to flow through all parts of the control box housing 1, and effectively avoid the existence of heat dissipation dead zones.

[0042] As a preferred technical solution in this embodiment, a number of electrical components 4 are provided inside the control box housing 1. The heat pipe heat conduction mechanism 8 is installed at the position of the high-heat electrical component 4. Specifically, the installation position of the heat pipe heat conduction mechanism 8 is restricted so that the heat pipe heat conduction mechanism 8 can absorb and utilize the heat emitted by the high-heat electrical component 4 and conduct the heat to the temperature regulation component to provide energy for the operation of the temperature regulation component; at the same time, the heat pipe heat conduction mechanism 8 can absorb the heat emitted by the high-heat electrical component 4, which can improve the heat dissipation effect of the high-heat electrical component 4.

[0043] As a preferred embodiment, the heat pipe heat conduction mechanism 8 includes a heat-absorbing plate 84, which is installed on the back of the high-heat-generating electrical component 4; and a diffuser head 82, which is disposed outside the temperature-regulating component. After the heat-absorbing plate 84 absorbs the heat emitted by the high-heat-generating electrical component 4, it can conduct the heat to the diffuser head 82. Specifically, a plurality of capillary heat pipes 83 are nested inside the diffuser head 82, the mounting clamp 81, and the heat-absorbing plate 84. The heat-absorbing end of the capillary heat pipe 83 is located inside the heat-absorbing plate 84, and the heat-dissipating end is located inside the diffuser head 82. A plurality of heat dissipation fins are provided on the surface of the diffuser head 82. The phase change material inside the thin heat pipe 83 undergoes a phase change, absorbing heat from the heat absorber plate 84 and conducting it to the diffuser head 82 for dissipation. This improves the heat dissipation effect on the high-heat electrical component 4 and provides energy for the operation of the temperature-regulating heat sink. It should be noted that since the diffuser head 82 needs to conduct heat to the temperature-regulating component, and the temperature-regulating component needs to rotate during operation, the diffuser head 82 has an arc shape when viewed from above and a U-shaped cross-section when viewed from the side. The temperature-regulating component can move inside the U-shaped diffuser head 82 and is activated by the heat conducted by the diffuser head 82.

[0044] As a preferred embodiment, the flow guide grille mechanism 9 includes a rotatably mounted mounting frame 93. The mounting frame 93 has an upper flow guide grille group 95 and a lower flow guide grille group 94 arranged in a vertical and horizontal configuration. The upper and lower flow guide grille groups 95 and 94 can be adjusted in tilt angle by a drive. Specifically, the flow guide grille mechanism 9 also includes a rotating seat 91, which is fixedly mounted on the inner side of the top of the control box housing 1 and corresponds to the position of the electric fan 7. A rotating platform 92 is fixedly connected to the outside of the mounting frame 93. The rotating platform 92 is rotatably mounted inside the rotating seat 91 via bearings, ensuring that the mounting frame 93 can rotate stably inside the control box housing 1. The lower flow guide grille group 94 has the same structure as the upper flow guide grille group 95, consisting of several parallel flow guide grille groups. The flow guide grille mechanism 9 is rotatably mounted inside the mounting frame 93 and can be driven to adjust its tilt angle. The flow guide grille mechanism 9 also includes a transmission linkage group 96 that cooperates with the lower flow guide grille group 94 and the upper flow guide grille group 95. It consists of a set of main transmission linkages and several secondary transmission linkages. One end of the secondary transmission linkage is hinged to the main transmission linkage, and the other end is fixedly fitted to the end of the flow guide grille. When the tilt angle of a set of flow guide grilles is adjusted, the transmission linkage group 96 can be used to drive and adjust several flow guide grilles synchronously. The lower flow guide grille group 94 and the upper flow guide grille group 95 are arranged in two layers, vertically and horizontally. By changing the tilt angle of the lower flow guide grille group 94 and the upper flow guide grille group 95, the direction of the airflow drawn by the electric fan 7 can be freely adjusted, so that turbulence is formed inside the control box housing 1.

[0045] As a preferred technical solution in this embodiment, the temperature regulation component includes an upper tilt angle adjustment mechanism 10, which is linked to the upper guide grille group 95 and drives the upper guide grille group 95 to move when the temperature changes; a lower tilt angle adjustment mechanism 11, which is linked to the lower guide grille group 94 and drives the lower guide grille group 94 to move when the temperature changes; and a reciprocating rotation mechanism 12, which is linked to the mounting frame 93 and drives the mounting frame 93 to reciprocate when the temperature changes. Specifically, the reciprocating rotation mechanism 12 is heated in the diffuser head 82 at the corresponding position and moves accordingly, and the mounting frame 93 is synchronously driven to reciprocate. The rotating mechanism 12 moves outward from the heat pipe heat conduction mechanism 8. The reciprocating rotating mechanism 12 senses a decrease in temperature and retracts to reset, then moves back into the heat pipe heat conduction mechanism 8. This cycle is repeated to drive the mounting frame 93 to reciprocate. When the mounting frame 93 reciprocates, it drives the upper tilt angle adjustment mechanism 10 and the lower tilt angle adjustment mechanism 11 to move in and out of the diffuser head 82 at the corresponding positions, causing the temperature sensed by the upper tilt angle adjustment mechanism 10 and the lower tilt angle adjustment mechanism 11 to change, thereby adjusting the tilt angle of the lower guide grille group 94 and the upper guide grille group 95.

[0046] As a preferred embodiment, the tilt adjustment mechanism 10 includes a memory metal spring 102 and a spiral sleeve 104. A spiral rod 105 is spirally connected to the spiral sleeve 104. When the memory metal spring 102 expands due to heat, it can drive the spiral sleeve 104 to move and drive the spiral rod 105 to rotate. Specifically, the spiral rod 105 is rotatably mounted on the mounting frame 93. The tilt adjustment mechanism 10 also includes a positioning cage 101, which is fixedly mounted on the bottom of the mounting frame 93 and is hollowed out to facilitate the memory metal spring 102 to deform in response to the external temperature of the positioning cage 101. A transmission platform 103 is snapped into the inside of the positioning cage 101. The transmission platform 103 and the inside of the positioning cage 101 are connected. The device has mutually cooperating limiting sliders and limiting grooves; the bottom end of the memory metal spring 102 is fixedly connected to the bottom of the inner side of the positioning cage 101, and the top end is fixedly connected to the bottom of the transmission table 103; the helix angle of the helical groove between the helical sleeve 104 and the helical rod 105 is greater than the equivalent friction angle, and the helical sleeve 104 and the helical rod 105 do not have a self-locking effect; when the memory metal spring 102 is heated, it expands and drives the transmission table 103 and the helical sleeve 104 to move, which in turn drives the helical rod 105 to rotate to one side. When the temperature of the memory metal spring 102 decreases, the memory metal spring 102 drives the transmission table 103 and the helical sleeve 104 to retract and reset, and drives the helical rod 105 to rotate to the other side to reset.

[0047] As a preferred technical solution in this embodiment, the upper tilt angle adjustment mechanism 10 further includes a transmission worm gear 106, which is fixedly connected to the spiral rod 105; and a transmission worm wheel 107, which is connected to the upper guide grille group 95, and the transmission worm wheel 107 and the transmission worm gear 106 mesh with each other. Specifically, the transmission worm wheel 107 is fixedly connected to a group of guide grilles in the upper guide grille group 95 that are close to the upper tilt angle adjustment mechanism 10. When the spiral rod 105 is driven to rotate, it drives the transmission worm gear 106 to rotate synchronously, thereby driving the transmission worm wheel 107 to rotate, and adjusting the tilt angle of the guide grilles in the upper guide grille group 95. The transmission worm gear 106 and the transmission worm wheel 107 have a self-locking effect to prevent the wind pressure received by the guide grille during operation from being transmitted to the memory metal spring 102, causing the memory metal spring 102 to deform.

[0048] As a preferred technical solution in this embodiment, the difference between the downward tilt adjustment mechanism 11 and the upward tilt adjustment mechanism 10 is that the downward tilt adjustment mechanism 11 further includes a transmission gear 111, which is connected to the lower guide grille group 94 via the transmission gear 111. Specifically, there are two sets of transmission gears 111. One set of transmission gears 111 is coaxially arranged with and fixedly connected to the transmission worm gear 107 in the downward tilt adjustment mechanism 11. The other set of transmission gears 111 is fixedly connected to a set of guide grilles in the lower guide grille group 94 that is close to the downward tilt adjustment mechanism 11. When the transmission worm gear 107 in the downward tilt adjustment mechanism 11 is driven to rotate, the two sets of meshing transmission gears 111 can be used to adjust the guide grilles in the lower guide grille group 94.

[0049] As a preferred technical solution in this embodiment, the reciprocating rotation mechanism 12 differs from the tilt adjustment mechanism 10 in that the reciprocating rotation mechanism 12 further includes a drive gear 121 and an arc-shaped rack 122, and the drive gear 121 and the arc-shaped rack 122 mesh with each other. Specifically, the reciprocating rotation mechanism 12 does not include a transmission worm 106 and a transmission worm wheel 107; the drive gear 121 is coaxially arranged with the screw rod 105 in the reciprocating rotation mechanism 12 and is fixedly connected to it; the arc-shaped rack 122 is fixedly installed on the inner side of the top of the control box housing 1; when the screw rod 105 in the reciprocating rotation mechanism 12 is driven to rotate, it can drive the drive gear 121 to rotate synchronously. Through the cooperation of the drive gear 121 and the arc-shaped rack 122, the other parts of the reciprocating rotation mechanism 12 except for the arc-shaped rack 122 are driven to rotate, thereby driving the mounting frame 93 to rotate.

[0050] As a preferred embodiment, when the reciprocating rotary mechanism 12 is heated, it can be driven by the drive gear 121 and the arc-shaped rack 122 to move outward from the heat pipe heat conduction mechanism 8, and after cooling down outside the heat pipe heat conduction mechanism 8, it returns to the inside of the heat pipe heat conduction mechanism 8. Specifically, the memory metal spring 102 in the reciprocating rotary mechanism 12 expands when heated in the corresponding diffuser head 82, thereby driving the drive gear 121 to rotate, and cooperating with the arc-shaped rack 122 to drive the other parts of the reciprocating rotary mechanism 12 except the arc-shaped rack 122 to rotate outward from the diffuser head 82; when the temperature of the memory metal spring 102 outside the diffuser head 82 decreases, the memory metal spring 102 contracts, driving the drive gear 121 to rotate in the opposite direction, so that the other parts of the reciprocating rotary mechanism 12 except the arc-shaped rack 122 move back into the diffuser head 82, and so on in a cycle. The reciprocating rotation mechanism 12 drives the mounting frame 93 to rotate back and forth. It should be noted that, in order to prevent the reciprocating rotation mechanism 12 from disengaging from the heat pipe heat conduction mechanism 8 at the corresponding position, a matching pin can be set on the rotating seat 91 and the rotating table 92 to limit the maximum angle of the reciprocating rotation of the mounting frame 93. It should also be noted that, since the power and current of the electrical component 4 change frequently during operation, its heat generation also changes, and consequently the heat conducted by the diffuser head 82 also changes. As long as the heat in the diffuser head 82 changes, the reciprocating rotation mechanism 12 can drive the mounting frame 93 to rotate due to the temperature change. At the same time, as long as the heat in the diffuser head 82 changes, the upper tilt angle adjustment mechanism 10 and the lower tilt angle adjustment mechanism 11 can adjust the tilt angle of the lower guide grille group 94 and the upper guide grille group 95 due to the temperature change.
