Description

Technical Field

[0001] The invention relates to a temperature control system for an electrical equipment box, belonging to the technical field of electrical equipment. Background Art

[0002] At present, the electrical equipment box is the control center that commands the reasonable distribution of electric energy among the components in the power supply line. It is the control link that reliably receives the upper power supply and correctly feeds the load electric energy. Improving the operational reliability of the distribution box is the goal of creating high-quality projects. However, most of the existing distribution boxes have simple structures, and the large number of electrical components installed in them are not convenient for heat dissipation and cooling.

[0003] At present, the general conventional heat dissipation is to open an air outlet on the top of the distribution box, add a fan at the position of the air outlet, and open an air inlet at the bottom (or on both sides), and use the fan to move the heat in the distribution box from bottom to top inside the box. Although this method continuously discharges hot gas from the air outlet and continuously enters from the air inlet to achieve cooling, heat is continuously generated when the electrical equipment is running. The electrical equipment located above or even in the middle of the box cavity is always in the upward flowing high-temperature gas. In addition, in a high-temperature environment (such as a hot summer), the temperature of the external air is also very high. The external air entering from the air inlet cannot effectively cool the electrical equipment in the distribution box, resulting in the electrical equipment in the distribution box being unable to work normally due to the high temperature. In severe cases, there is even a fire hazard. Therefore, an electrical equipment box temperature control system is proposed. Summary of the Invention

DETAILED DESCRIPTION

[0038] The present invention is described below with specific examples, but is not intended to be limiting of the invention.

[0039] Example 1

[0040] like Figures 1-11As shown, in this embodiment, a temperature control system for an electrical equipment box is provided, including a box 1, a box door 101 is installed on the front side of the box 1, a temperature exhaust box 2 is installed on the box 1, a fan 3 is installed inside the temperature exhaust box 2, and a dust cover 201 is provided just above the fan 3. The gas in the temperature exhaust box 2 can be discharged outward from the dust cover 201. A main exhaust pipe 4 is installed on the left and right side walls of the box 1. The upper ends of the two main exhaust pipes 4 are both connected to the temperature exhaust box 2. There are multiple exhaust pipes evenly distributed on the main exhaust pipes 4. An interface 401, a plurality of branch exhaust pipes 5 are evenly distributed in the inner cavity of the box body 1, and a plurality of air intake ports 501 opened on the side wall of each branch exhaust pipe 5 can absorb the heat generated by the electrical components near the air intake port 501, and each branch exhaust pipe 5 is rotatably connected to the corresponding interface 401 through a connecting component 6. When the fan 3 is started, the gas with heat in the inner cavity of the box body 1 is sucked into the main exhaust pipe 4 through the branch exhaust pipe 5, and the main exhaust pipe 4 introduces the gas with heat into the exhaust box 2 and then discharges it.

[0041] like Figures 8-10 As shown, in order to be able to connect the branch exhaust pipe 5 to the interface 401 of the main exhaust pipe 4, and at the same time, after the branch exhaust pipe 5 is folded, the folded branch exhaust pipe 5 can be disconnected from the interface 401, the connecting component 6 includes a ball head 601 connected to the branch exhaust pipe 5 as a whole, the ball head 601 passes through the branch exhaust pipe 5 in the axial direction, and a rotating seat 602 with a hollow middle part is rotatably connected to the ball head 601. The end of the rotating seat 602 away from the ball head 601 is connected along the interface 401 rotates on the interface 401 in the axial direction, and a ring block with an "L"-shaped cross section is provided on the side of the rotating seat 602. An annular groove with an "L" cross section is opened at the end of the interface 401. The ring block is adapted to the annular groove. When the ring block is rotated and connected to the inside of the annular groove, the rotating seat 602 can be rotated and connected to the interface 401. The outer surface of the ball head 601 fits the contour surface of the hollow position of the rotating seat 602. When the exhaust pipe 5 is rotated to coincide with the axis of the interface 401, as shown Figure 9 As shown, the through position of the ball head 601 is aligned with the hollow position of the rotating seat 602, so that the exhaust pipe 5 is connected to the interface 401. When the exhaust pipe 5 is rotated to be perpendicular to the axis of the interface 401, as shown in FIG. Figure 10 As shown, the through position of the ball head 601 is staggered with the hollow position of the rotating seat 602, so that the outer surface of the ball head 601 closes the hollow position of the rotating seat 602 (interface 401), and the exhaust pipe 5 is perpendicular to the axis of the interface 401 and its inner cavity is not connected.

[0042] like Figure 7 、 Figure 8As shown, in the state where the branch exhaust pipe 5 is connected to the interface 401, in order to increase the stability of the connection between the branch exhaust pipe 5 and the interface 401 and prevent the branch exhaust pipe 5 from being disconnected from the interface 401 after rotating on its own, the connecting assembly 6 is provided with a clamping portion for clamping the branch exhaust pipe 5, and the clamping portion includes a mounting groove 7 provided on the rotating seat 602, and a clamping block 9 with a spherical clamping end is installed inside the mounting groove 7 through a spring 8. The end of the spring 8 away from the clamping block 9 is provided with a blocking cap 11 for blocking the opening of the mounting groove 7. The clamping block 9 and the spring 8 are installed in sequence. After entering the interior of the installation groove 7, the blocking cap 11 is screwed into the opening of the installation groove 7 by means of a thread, so that the clamping block 9 and the spring 8 are installed into the interior of the installation groove 7. At this time, the clamping end of the clamping block 9 extends from the end of the installation groove 7 away from the blocking cap 11. When the clamping end of the clamping block 9 is pressed, the clamping block 9 compresses the spring 8 and retracts into the interior of the installation groove 7. After being released, the spring 8 can immediately eject the clamping end of the clamping block 9. The clamping end of the clamping block 9 passes through the side wall of the rotating seat 602 and is movably clamped into the interior of the clamping groove 10. The clamping groove 10 is provided on the protruding block of the exhaust pipe 5.

[0043] like Figure 7 、 Figure 8 As shown, when the sub-exhaust pipe 5 is rotated to coincide with the axis of the interface 401, the clamping end of the clamping block 9 is clamped in the inside of the clamping groove 10. At this time, the sub-exhaust pipe 5 can be fixed in this state, ensuring the connection between the sub-exhaust pipe 5 and the main exhaust pipe 4, and preventing the sub-exhaust pipe 5 from rotating. When the sub-exhaust pipe 5 needs to be retracted, a certain force is applied to pry the sub-exhaust pipe 5, and the spherical clamping end of the clamping block 9 is squeezed and pressed into the inside of the mounting groove 7 by the side of the clamping groove 10, so that the clamping block 9 and the clamping groove 10 are forcibly disengaged. The sub-exhaust pipe 5 can be rotated on the rotating seat 602, so that the sub-exhaust pipe 5 is rotated to be perpendicular to the axis of the interface 401. At this time, the sub-exhaust pipe 5 is attached to the inner wall of the box body 1 and retracted;

[0044] Furthermore, an elastic C-shaped clamp 12 is provided on the inner wall of the box body 1. The inner diameter of the C-shaped clamp 12 is interference fit with the outer diameter of the branch exhaust pipe 5. After the branch exhaust pipe 5 is attached to the inner wall of the box body 1, the branch exhaust pipe 5 is clamped on the C-shaped clamp 12, which can better fix the branch exhaust pipe 5 on the inner wall of the box body 1 and retract it.

[0045] Further: Figure 11As shown, in order to be able to adjust the size of the air intake port 501, the internal movable connection of the sub-exhaust pipe 5 is provided with a hollow sleeve 13, and the end of the sleeve 13 away from the ball head 601 is sealed and extends to the outside of the sub-exhaust pipe 5, and a through hole 1301 corresponding to the air intake port 501 is provided on the side wall of the sleeve 13. When the sleeve 13 is movable, the degree of interlacing between the through hole 1301 and the air intake port 501 can be adjusted, and a limiting groove 502 is provided on the side wall of the sub-exhaust pipe 5, and a limiting rod 1302 is provided inside the limiting groove 502, and the limiting rod 1302 is fixed on the side wall of the sleeve 13.

[0046] like Figure 11 As shown, the limit rod 1302 can be a bolt, which is engaged with the side wall of the sleeve 13 by the threaded end to achieve the fixed connection between the limit rod 1302 and the sleeve 13, and the limit groove 502 is opened along the axis of the sub-exhaust pipe 5 at right angles. At this time, the sleeve 13 can be axially rotated inside the sub-exhaust pipe 5 by the limiting effect of the limit groove 502 and the limit rod 1302. When the sleeve 13 rotates in the sub-exhaust pipe 5 and the limit rod 1302 slides from one end of the limit groove 502 to the other end, the air inlet 501 and the through hole 1301 are more and more staggered. This process is a process of reducing or even closing the air inlet 501. Conversely, when the sleeve 13 rotates in the sub-exhaust pipe 5 and the limit rod 1302 slides from the other end of the limit groove 502 to one end, the air inlet 501 and the through hole 1301 are less and less staggered. This process is a process of increasing or even fully opening the air inlet 501.

[0047] In addition, the limiting rod 1302 can be a bolt, and the threaded end is engaged with the side wall of the sleeve 13 to achieve a fixed connection between the limiting rod 1302 and the sleeve 13. The limiting groove 502 is opened in a direction parallel to the axis of the branch exhaust pipe 5. At this time, the sleeve 13 can be pulled along the axis of the branch exhaust pipe 5 to adjust the degree of intersection between the through hole 1301 and the air intake 501, thereby adjusting the size of the air intake 501.

[0048] When cooling the box 1, the exhaust pipe 5 is pre-installed as follows: Figure 3 The status shown is turned to Figure 2 In the state shown, the sizes of the air intakes 501 on all the branch exhaust pipes 5 are adjusted one by one according to the above operations. Near the electrical equipment with high heat generation, the opening of the air intake 501 is adjusted to be larger, and near the electrical equipment with low heat generation, the opening of the air intake 501 is adjusted to be smaller. At this time, the heat at various positions in the box 1 can be directly inhaled into the branch exhaust pipe 5 from the air intake 501, and the heat source in the box 1 is dissipated in a targeted manner. Finally, it is gathered to the interior of the exhaust box 2 through the main exhaust pipe 4 and discharged from the exhaust box 2, which can avoid the high-temperature gas from flowing in the inner cavity of the box 1, prevent the electrical equipment in the box 1 from working in a high-temperature environment for a long time, keep the electrical equipment working stably, and avoid the risk of fire.

[0049] Example 2

[0050] like Figure 1 、 Figure 2 、 Figure 12 Figure 21 As shown, on the basis of Example 1, in order to allow external air to enter the box body 1 and to cool the incoming air during the process of external air entering the interior of the box body 1, an air intake box 14 is fixedly installed at the bottom of the box body 1, and the air intake box 14 is made of a good thermal conductive material, such as metal aluminum. A plurality of air intake channels 1401 are opened on the side wall of the air intake box 14, one end of the air intake channel 1401 is connected to the outside, and the other end is connected to the inner cavity of the box body 1, and a serpentine cooling water channel 1402 is provided inside the air intake box 14, and a water tank 17 for containing cooling water is fixedly connected to the bottom of the box body 1, and both ends of the cooling water channel 1402 are connected to the inner cavity of the water tank 17 through a water inlet pipe 15 and a water outlet pipe 16 respectively, and the coolant between the cooling water channel 1402 and the water tank 17 circulates through a drive component 18;

[0051] like Figure 14 、 Figure 16 As shown, after the fan 3 is started, the hot gas in the box 1 is discharged, and the external air enters the box 1 from the inside of the air inlet 1401 (the gas flows along the Figure 14 、 Figure 16 The hollow arrow shown in the figure passes through the air inlet duct 1401). When the gas is inside the air inlet duct 1401, the coolant in the cooling water channel 1402 absorbs the heat of the gas in the air inlet duct 1401 and cools it, thereby lowering the temperature of the gas entering the box body 1 and further lowering the temperature of the inner cavity of the box body 1. At the same time, through the drive component 18, the cooling water in the water tank 17 enters the cooling water channel 1402 from the water inlet pipe 15, and then flows through the cooling water channel 1402 (the cooling water is as shown in the figure). Figure 14 During this process, the cooling water will take away the heat, prompting the cooling water in the cooling water channel 1402 to continuously cool the gas in the air inlet channel 1401, and then cool the inner cavity of the box body 1, so that the electrical equipment will not be damaged by high temperature.

[0052] Further: Figure 12-15As shown, in order to drive the coolant between the cooling water channel 1402 and the water tank 17 to circulate, the drive assembly 18 includes a transmission shaft 1801, which is arranged inside the box body 1, and the upper end of the transmission shaft 1801 extends to the interior of the exhaust box 2 and is connected to the rotating shaft of the fan 3 through a belt, and the lower end of the transmission shaft 1801 is fixedly connected to the turntable 1802, and the drive assembly 18 also includes a power column 1803, which is fixedly connected to the side wall of the air intake box 14, and the inner cavity of the power column 1803 is communicated with the cooling water channel 1402, and the power column 180 3 is slidably connected to a piston rod 1804, the end of which is connected to the side wall of the turntable 1802 away from the center of the circle via a connecting rod 1805, and a one-way component 1806 is connected in series to the water inlet pipe 15 and the water outlet pipe 16. When the piston rod 1804 slides to cause the power column 1803 to draw coolant from the cooling water channel 1402, the one-way component 1806 controls the water inlet pipe 15 to open and the water outlet pipe 16 to close. When the piston rod 1804 slides to push the coolant from the power column 1803 into the cooling water channel 1402, the one-way component 1806 controls the water inlet pipe 15 to close and the water outlet pipe 16 to open.

[0053] The one-way assembly 1806 comprises a T-shaped tube body with a ball valve installed inside. The tube body is provided with three ports, two of which are the liquid inlet and outlet ports. The liquid inlet and outlet ports of the tube body are perpendicular to each other. The other end of the tube body is sealed by a plug cap, and the inner end of the plug cap is provided with a guide post, and the ball valve is slidably connected to the guide post.

[0054] Take the one-way component 1806 on the water inlet pipe 15 as an example: the liquid outlet is connected to the water inlet pipe 15, and the liquid inlet is connected to the water tank 17. When the piston rod 1804 draws the liquid in the cooling water channel 1402 in the power column 1803, that is, when the cooling water channel 1402 absorbs the liquid, the ball valve moves upward, causing the liquid outlet to be connected to the liquid inlet (such as Figure 19 As shown), the coolant in the water tank 17 is sucked from the water inlet pipe 15 to the interior of the cooling water channel 1402. When the piston rod 1804 stops moving, the ball valve moves downward and blocks the liquid outlet and the liquid inlet (as shown). Figure 18 As shown), when the piston rod 1804 pushes the coolant in the power column 1803 into the interior of the cooling water channel 1402, that is, when the cooling water channel 1402 is discharging liquid, the water inlet pipe 15 is blocked, so that the water inlet pipe 15 can unidirectionally inject the coolant in the water tank 17 into the interior of the cooling water channel 1402;

[0055] Refer to Figure 20 and Figure 21, and referring to the description in the previous paragraph, it can be seen that when the piston rod 1804 is pulled and pushed inside the power column 1803, the one-way component 1806 on the water outlet pipe 16 can make the coolant flow back from the inside of the cooling water channel 1402 to the inside of the water tank 17 in one direction, thereby prompting the fan 3 to drive the water in the water tank 17 and the cooling water channel 1402 to circulate while running.

[0056] Further: Figure 4 、 Figure 17 As shown, in order to cool the cooling water in the water outlet pipe 16, the water outlet pipe 16 is bent into a "U" shape, and a plurality of heat dissipation fins 19 are fixedly connected to the water outlet pipe 16. The water outlet pipe 16 and the heat dissipation fins 19 are made of aluminum with good thermal conductivity. The lower end of any main exhaust pipe 4 is connected and extends above the heat dissipation fins 19 to suck the gas between the gaps of the heat dissipation fins 19;

[0057] When the cooling water absorbs heat inside the cooling water channel 1402 and flows into the water outlet pipe 16, the heat dissipation fins 19 will dissipate the heat in the cooling water. When the main exhaust pipe 4 sucks the gas between the gaps of the heat dissipation fins 19, the heat dissipation fins 19 are air-cooled, and then the coolant in the water outlet pipe 16 can be quickly cooled. The cooled coolant enters the water tank 17 and is then recycled.

[0058] Working principle: Figure 4 As shown, a controller 20 and a temperature sensor 21 are also installed inside the box 1. The controller 20 is electrically connected to the temperature sensor 21 and the fan 3. The controller 20 controls the operation of the temperature sensor 21 and the fan 3. The temperature sensor 21 is set to sense the temperature inside the box 1 and feed back the temperature information to the controller 20. After receiving the temperature information, the controller 20 controls the fan 3 to work. The fan 3 can drive the fan blades on the fan 3 to rotate. The rotation of the fan blades can generate airflow to cause the gas in the exhaust chamber to be blown out. At this time, the gas in the box 1 is sucked through the main exhaust pipe 4 and the branch exhaust pipe 5, and then the gas with heat is discharged To the outside world, in addition, external gas is injected into the box body 1 through the air inlet duct 1401, so that the box body 1 can be cooled by air. When the fan 3 is working, the transmission shaft 1801 is rotated. Driven by the turntable 1802, the connecting rod 1805 drives the piston rod 1804 to slide back and forth in the power column 1803, so as to promote the circulation of cooling water in the water tank 17 and the cooling water channel 1402.
