Description

[0002] In the power system, outdoor desktop distribution boxes are one of the common power distribution facilities. These distribution boxes usually cause the temperature inside the box to rise due to the increase in ambient temperature and the heating of internal electrical components. Especially in hot summer weather and peak electricity consumption periods, since the distribution box itself lacks an effective ventilation and heat dissipation system and only relies on natural heat dissipation holes for heat dissipation, the temperature inside the box can easily exceed the safe operating range. This will not only cause the low-voltage switch to trip frequently and damage electrical equipment, but may even cause fire accidents, seriously affecting the stability and safety of power supply.

[0003] The heat dissipation method of natural heat dissipation holes cannot meet the needs of efficient heat dissipation, especially under extreme climatic conditions.

[0038] Specifically, the installation assembly 100 includes a distribution box body 101 and a tripod 102 arranged at the bottom of the distribution box body 101. The tripod 102 is connected to the cooling device through a support 103 and is used to suspend the cooling device.

This embodiment is different from the first embodiment in that the temperature control module 205 can effectively monitor and control the temperature inside the distribution box to ensure the safe operation of the electrical equipment, while having good portability and maintainability.

Install a dust cover 202 on the side wall of the housing 201 to protect the internal components from dust intrusion. Install a rectifier module 203 inside the housing 201, which is used to convert the AC power connected to the copper busbar in the distribution box body 101 into 24V DC power for use by the cooling element 204, the temperature control module 205 and the speed regulator 206. Install the cooling element 204 on the top of the rectifier module 203 to ensure that it is tightly connected to the rectifier module 203 to ensure that the cooling element 204 works normally. Install the temperature control module 205 on the side wall of the rectifier module 203 to monitor the temperature in the distribution box body 101 and control the start and stop of the cooling element 204 according to the temperature change. Install the speed regulator 206 on the side wall of the temperature control module 205, which is used to adjust the speed of the fan 204e in the cooling element 204, thereby controlling the air flow speed. The rectifier module 203 is used to supply power to the speed regulator 206 , the temperature control module 205 and the cooling element 204 , ensuring that all electrical connections are correct.

[0046] Example 3, reference Figure 3 to Figure 8 , which is the third embodiment of the present invention. This embodiment is different from the above embodiments in that the cooling efficiency is improved through its unique cooling fin design and air flow optimization measures to ensure smooth guidance of the airflow.

[0047] Specifically, the cooling member 204 includes a shell 204a disposed at the bottom end of the tripod 102, a drain port 204k is installed on the side wall of the shell 204a for discharging cooling water, and an air inlet 204b and an air outlet 204c are installed at both ends of the shell 204a.

[0048] Furthermore, the cooling member 204 also includes a bump block 204d arranged inside the air inlet 204b and the air outlet 204c for reducing eddy currents, and a fan 204e is installed at the end of the bump block 204d for air intake and exhaust, and the bump block 204d is smoothly arranged, and an array of perforations is distributed at the bump block 204d.

[0049] Furthermore, the cooling member 204 further includes a heat sink 2041 disposed at the bottom end of the shell 204a, the bottom end of the heat sink 2041 is connected to the rectifier module 203, and the rectifier module 203 and the shell 204a are connected via a cross support plate 204f.

[0050] Furthermore, the cooling member 204 further includes a cavity 204g disposed inside the shell 204a, a fixing plate 204h is installed inside the cavity 204g, and an air inlet gap 204i is disposed between the fixing plate 204h and the wall thickness of the shell 204a.

[0051] Furthermore, the cooling member 204 also includes a cooling fin 204j arranged on the top of the fixing plate 204h, and the cooling fin 204j includes a middle fin B arranged opposite to the air inlet 204b, and both sides of the middle fin B are cooling fins 204j that guide air in opposite directions.

[0052] Furthermore, the cooling member 204 also includes a drainage groove E arranged in the X-axis direction of the cooling fin 204j. The top view of the cooling fin 204j is in the shape of a water drop with a tail hook D, and the tail hook D is used to guide the drainage groove E to receive the airflow on both sides.

[0053] Furthermore, the middle portion A of the cooling fin 204j is the thickest and is convex, while the two ends are gradually thinner, and the cooling fin 204j becomes thinner as it is closer to the tail hook D, and a connection portion C is provided.

[0054] The rest of the structure is the same as that of Example 2.

[0055] Operation process: First, when the device is in use, the cooling member 204 needs to be suspended at the bottom of the distribution box body 101 through the support member 103, wherein the cross bar 103a is fixed in the tripod 102, and then the cooling member 204 is fixed by the inclined hanging rod 103b. When the internal temperature of the distribution box body 101 is higher than the set value, the temperature control module 205 controls the cooling member 204 to start, the refrigeration system starts working, the cooling sheet 204j starts to cool down, and at the same time the fan 204e starts working, and the hot air generated by the distribution box body 101 is transported to the cold slice 204j through the air inlet 204b pipe (placed at the bottom of the distribution box body 101) through the concave and convex block 204d for cooling, wherein the concave and convex block 204d is used to reduce eddy currents, and the cold slice 204j is wavy as a whole, wherein the middle slice B receives the hot air guided in by the fan 204e, and then diffuses to both sides through the drainage groove E on the middle slice B, and the cooling sheets 204 on both sides of the middle slice B 04j, the bulge at the middle part A of the cooling fin 204j can effectively increase the retention time of hot air and improve the cooling efficiency, wherein the cooled gas is transported to the next row through the drainage grooves E in the cooling fins 204j on both sides of the middle fin B, and at the same time, the tilting at the tail hook D can effectively receive the wind guided by the previous cooling fin 204j, and then the cooled gas is transported back to the distribution box through the fan 204e in the air outlet 204c, through the concave and convex block 204d to reduce the eddy current, and then to the air outlet 204c pipe (placed at the top inside the distribution box body 101), and the gas in the distribution box body 101 is continuously circulated to cool down the temperature, and the condensed water generated during the refrigeration process is discharged through the drain outlet 204k pipe, and the drain outlet 204k pipe has a one-way valve. When the condensed water accumulates to a certain extent, the water flows from the inside to the outside (when the fan 204e is working, due to the action of the one-way valve, the gas cannot be sucked into this pipe), and the temperature drops to the set threshold and the refrigeration system is shut down. The concave and convex block 204d is used to make the air after the other cold slices are cut by the fan. The fan 204e is adjusted by the speed regulator 206 to adjust the air flow speed.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
