Technical Field

[0001] This application relates to the technical field of electrical equipment, and particularly to an electrical component spacer. Background Art

[0002] In the industrial and construction fields, electrical equipment such as distribution cabinets and distribution boxes are important components of the power system. Electrical components such as contactors and circuit breakers are installed inside these electrical equipment, and the electrical components are installed side by side and separated by spacers.

[0003] Electrical components generate heat during operation. If effective heat dissipation cannot be achieved, it will cause the temperature of the electrical components to rise, affecting their service life and even leading to safety accidents. Currently, heat dissipation is often achieved by setting heat dissipation grooves or holes on the spacers.

[0004] However, this heat dissipation method relies on natural air convection, and the heat dissipation effect is not good. It is difficult to meet the heat dissipation requirements of high-power or high-density electrical components. Moreover, there is non-uniformity in natural air convection, which may cause some electrical components to overheat due to insufficient heat dissipation. Utility Model Content

[0046] See Figure 1 、 Figure 2 、 Figure 3 As shown in

[0047] See Figure 1 、 Figure 2 、 Figure 3 ,an electrical component spacer provided by the embodiments of the present application includes two heat-conducting seats 1 and a mounting seat 2 connected between the two heat-conducting seats 1. A heat dissipation cavity 21 is arranged in the mounting seat 2. One end of the heat-conducting seat 1 extends into the heat dissipation cavity 21. A ventilation opening 22 communicating with the heat dissipation cavity 21 and a heat dissipation fan 3 are arranged on the mounting seat 2.

[0048] The heat-conducting seat 1 is used to mount and support electrical components such as contactors and circuit breakers, and is used to transfer the heat generated by the electrical components during operation. The heat-conducting seat 1 is made of a metal material, which not only has a certain rigidity and strength, but also has good heat-conducting performance. Exemplarily, the heat-conducting seat 1 is made of aluminum. The mounting seat 2 is used to be mounted on the mounting rails inside electrical equipment such as distribution cabinets and distribution boxes, and is used to separate adjacent electrical components. A heat dissipation cavity 21 is arranged in the mounting seat 2. Since one end of the heat-conducting seat 1 extends into the heat dissipation cavity 21, the heat generated by the electrical components during operation can be transferred to the air in the heat dissipation cavity 21 through the heat-conducting seat 1. A ventilation opening 22 communicating with the heat dissipation cavity 21 and a heat dissipation fan 3 are arranged on the mounting seat 2. The heat dissipation fan 3 is used to blow air into the heat dissipation cavity 21 to accelerate the convection of hot and cold air in the heat dissipation cavity 21. The hot air in the heat dissipation cavity 21 can be discharged through the ventilation opening 22. Among them, the number of the ventilation opening 22 and the heat dissipation fan 3 can be one, two or more than two, and no specific limitation is made here.

[0049] The electrical component spacer provided by the embodiment of the present application uses the heat conduction seat 1 to install electrical components, and uses the mounting seat 2 to separate adjacent electrical components; the heat generated by the electrical components during operation is transferred from the heat conduction seat 1 to the air in the heat dissipation cavity 21 of the mounting seat 2, and the hot air in the heat dissipation cavity 21 is discharged through the ventilation openings 22. By blowing air into the heat dissipation cavity 21 through the heat dissipation fan 3, the convection of hot and cold air in the heat dissipation cavity 21 is accelerated, thereby promoting the conduction and release of heat on the heat conduction seat 1, improving the heat dissipation effect of the electrical components, reducing the thermal damage of the electrical components, and prolonging the service life of the electrical components; compared with the prior art, it can not only meet the heat dissipation requirements of high-power or high-density electrical components, but also increase the uniformity of the convection of hot and cold air, avoiding the situation that some electrical components overheat due to insufficient heat dissipation.

[0050] In some embodiments, referring to Figure 1 , Figure 2 , Figure 3 , the mounting seat 2 includes a cuboid-shaped mounting box, which is surrounded by a front wall, a rear wall, a left wall, a right wall, a top wall and a bottom wall, and the inner cavity of the mounting box forms the heat dissipation cavity 21. Among them, the front wall is parallel to the rear wall, the left wall is parallel to the right wall, and the top wall is parallel to the bottom wall. Two front wall holes are provided on the front wall of the mounting box, and two heat dissipation fans 3 are respectively arranged at the two front wall holes and are connected to the front wall through fasteners such as bolts. Two groups of ventilation openings 22 are provided on the rear wall of the mounting box, and each group of ventilation openings 22 includes five ventilation openings 22 arranged at intervals from top to bottom, and each ventilation opening 22 is a long strip structure extending in the horizontal direction. A left wall hole is provided on the left wall of the mounting box, and one heat conduction seat 1 is connected to the left wall through fasteners such as bolts, and one end of the heat conduction seat 1 passes through the left wall hole and extends into the heat dissipation cavity 21. A right wall hole is provided on the right wall of the mounting box, and the other heat conduction seat 1 is connected to the right wall through fasteners such as bolts, and one end of the heat conduction seat 1 passes through the right wall hole and extends into the heat dissipation cavity 21.

[0051] In some embodiments, referring to Figure 1 , Figure 2 , Figure 3 , the heat conduction seat 1 includes a mounting portion 11 and a connecting portion 12. One end of the connecting portion 12 is connected to the mounting portion 11, and the other end of the connecting portion 12 is connected to the mounting seat 2 and extends into the heat dissipation cavity 21. The mounting portion 11 is used to mount electrical components. Exemplarily, the mounting portion 11 is integrally L-shaped, including a vertical section and a horizontal section. The vertical section is attached to the end face of one end of the connecting portion 12 and is connected to each other through fasteners such as bolts. The lower end of the vertical section is connected to one end of the horizontal section, and the connecting portion 12 can be connected to the mounting seat 2 through fasteners such as bolts.

[0052] During installation, place the electrical components on the horizontal section and fix them with bolts. The heat generated by the electrical components during operation is sequentially transferred to the heat dissipation cavity 21 of the mounting base 2 through the mounting portion 11 and the connecting portion 12. After installation, the electrical components can also be in contact with both the horizontal section and the vertical section simultaneously, which can increase the contact area between the electrical components and the mounting portion 11 and improve the efficiency of heat transfer.

[0053] In some embodiments, refer to Figure 1 , Figure 2 , Figure 3 , at least one connecting portion 12 is movably connected to the mounting base 2, and a distance adjusting component 4 for adjusting the distance between the two connecting portions 12 is provided on the mounting base 2. By means of the distance adjusting component 4, the position of at least one connecting portion 12 can be adjusted, and then the distance between the electrical components mounted on the two mounting portions 11 can be adjusted to adapt to electrical equipment of different specifications, improving the adaptability and flexibility.

[0054] Exemplarily, one of the connecting portions 12 passes through the left wall hole of the left wall and is connected to the left wall by fasteners such as bolts; the other connecting portion 12 passes through the right wall hole of the right wall and moves within the right wall hole; the distance adjusting component 4 is connected to the connecting portion 12 passing through the right wall hole for adjusting the position of this connecting portion 12 within the right wall hole so that this connecting portion 12 approaches or moves away from the other connecting portion 12, thereby achieving the purpose of adjusting the distance between the two connecting portions 12. For example, the distance adjusting component 4 can be an electric push rod, a lead screw adjusting mechanism, etc.

[0055] Exemplarily, both connecting portions 12 are movably connected to the mounting base 2, and the distance adjusting component 4 is used to simultaneously drive the two connecting portions 12 to approach or move away from each other. For example, one of the connecting portions 12 passes through the left wall hole of the left wall and moves within the left wall hole, and the other connecting portion 12 passes through the right wall hole of the right wall and moves within the right wall hole. The distance adjusting component 4 is simultaneously connected to the two connecting portions 12 to drive the two connecting portions 12 to approach or move away from each other, thereby achieving the purpose of adjusting the distance between the two connecting portions 12.

[0056] In some embodiments, refer to Figure 1 , Figure 2 , Figure 3 , the distance adjusting component 4 includes a rotating rod 41. The rotating rod 41 has two external thread sections 411 with opposite helix directions. Two movable blocks 42 are respectively threadedly connected to the two external thread sections 411. The two movable blocks 42 are respectively connected to the two connecting portions 12. The two ends of the rotating rod 41 are rotatably connected to the mounting base 2, and at least one end of the rotating rod 41 is located outside the mounting base 2. During operation, only by controlling the rotation of the rotating rod 41, the two movable blocks 42 can be driven to approach or move away from each other along the rotating rod 41, and then the two connecting portions 12 can be driven to approach or move away from each other through the two movable blocks 42, thereby adjusting the distance between the two connecting portions 12.

[0057] Exemplarily, the rotating rod 41 can be arranged in the heat dissipation cavity 21 of the mounting base 2, and one end of the rotating rod 41 passes through the mounting base 2 and extends to the outside of the mounting base 2. During operation, the operator holds the end of the rotating rod 41 and provides a force to drive the rotating rod 41 to rotate.

[0058] Exemplarily, a fixing plate 44 is connected above the top wall of the mounting base 2. The fixing plate 44 is generally in a U-shaped shape. The rotating rod 41 is arranged parallel to the moving direction of the connecting portion 12, and its two ends are respectively rotatably connected to the fixing plate 44, so that the rotating rod 41 rotates around its own axis. A long strip-shaped groove 23 extending in the direction from one connecting portion 12 to the other connecting portion 12 is arranged on the top wall of the mounting base 2. Two movable blocks 42 pass through the long strip-shaped groove 23 and can move in the long strip-shaped groove 23. During operation, the operator holds the end of the rotating rod 41 and provides a force to drive the rotating rod 41 to rotate.

[0059] In some embodiments, referring to Figure 2 、 Figure 3 A knob 43 is connected to the end of the rotating rod 41 located outside the mounting base 2. By providing the knob 43, it is not only convenient for the operator to grip, making it easier for the operator to rotate the rotating rod 41, but also can increase the torque on the rotating rod 41, making the rotation of the rotating rod 41 more labor-saving, so that it can be easily operated even in a narrow space or an environment with dense equipment.

[0060] In some embodiments, referring to Figure 3 A ventilation hole 121 is arranged on the connecting portion 12. By providing the ventilation hole 121, the heat dissipation area of the connecting portion 12 in the heat dissipation cavity 21 is increased, and the heat dissipation efficiency is improved. Exemplarily, a plurality of ventilation holes 121 are arranged on the connecting portion 12, and each ventilation hole 121 penetrates the connecting portion 12 in the direction from the front wall to the rear wall. This allows air to flow through the ventilation hole 121, which helps to quickly transfer the heat from the inside of the connecting portion 12 to the outside, thereby further improving the heat dissipation efficiency.

[0061] In some embodiments, referring to Figure 3 A heat conduction tube 5 and a heat conduction rod 6 are arranged in the heat dissipation cavity 21 and between the two connecting portions 12. The heat conduction tube 5 is connected to one of the connecting portions 12, and the heat conduction rod 6 is connected to the other connecting portion 12. By providing the heat conduction tube 5 and the heat conduction rod 6, the heat dissipation area can be further increased, and the heat dissipation efficiency can be improved.

[0062] Exemplarily, the number of heat conduction tubes 5 is consistent with and corresponds one by one to the number of heat conduction rods 6; during the movement of the connecting portion 12, the heat conduction rod 6 can be selectively inserted into the corresponding heat conduction tube 5. A heat dissipation fin 61 extending along the length direction thereof is provided on the heat conduction rod 6, and a strip-shaped notch 51 for inserting the heat dissipation fin 61 is provided on the heat conduction tube 5. The design of the heat dissipation fin 61 not only increases the heat dissipation area, but also optimizes the air flow path, reduces turbulence and resistance, and further improves the heat dissipation performance.
