Description

Technical Field

[0001] The utility model belongs to the technical field of heat dissipation in power distribution rooms, and in particular relates to a heat dissipation assembly for power equipment in a power distribution room. Background Art

[0002] For the high and low voltage distribution room, it is like a "furnace" in summer. Its heat dissipation mainly relies on air conditioning refrigeration and / or top axial flow fan exhaust heat dissipation, but its indoor ambient temperature is still higher than 37°C, and its heat dissipation effect is not good, and the heat dissipation power consumption is high. The heat source in the distribution room mainly comes from the heat source of the factory transformer itself at 65°C, and the heat source of the 220 kW heavy-duty inverter of the circulating pump itself at 45°C. When the temperature in the distribution room is high, its internal components are prone to aging, thereby shortening the service life of the equipment. In addition, when the temperature in the distribution room is high, the microcomputer protector may malfunction, which will affect the normal operation of the equipment. Utility Model Content

The advantages and features of the present invention will become clearer according to the following description and claims. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0028] like Figure 1 As shown, this embodiment provides a heat dissipation assembly for power equipment in a power distribution room, including a heat absorption cover 1, a ventilation pipe 2 and an exhaust device 3. The heat absorption cover 1 is arranged in a power distribution room 4 and covers the heat dissipation window 51 of the power equipment 5 (see Figure 1 and Figure 2 As shown), one end of the ventilation pipe 2 is connected to the interface of the heat absorption cover 1, and the other end of the ventilation pipe 2 passes through the outside of the power distribution room 4, and the air inlet of the exhaust device 3 is connected to the other end of the ventilation pipe 2. The structure is simple. The heat absorption cover of the heat dissipation assembly of the power equipment in the power distribution room can be directly covered on the heat dissipation window of the power equipment, so that the exhaust device can directly absorb the heat in the power equipment when exhausting air, and minimize the heat emitted by the power equipment from radiating into the power distribution room, so that the temperature in the power distribution room will not be too high; specifically, there are multiple heat absorption covers 1, and the power distribution room 4 has multiple power equipment 5. The multiple heat absorption covers 1 correspond to the multiple power equipment 5 one by one, and each of the heat absorption covers 1 is covered at the heat dissipation window 51 corresponding to the power equipment 5, so that the heat emitted by the multiple power equipment can be timely dissipated through the heat dissipation assembly of the power equipment in the power distribution room.

[0029] The heat absorption cover can be bolted to the casing of the power equipment by screws, and completely covers the heat dissipation window of the power equipment.

[0030] See Figure 1 and Figure 3 As shown, the ventilation pipe 2 in the above technical solution includes a ventilation main pipe 21 and multiple ventilation branch pipes 22. The multiple ventilation branch pipes 22 correspond to the multiple power equipment 5 one by one. One end of each ventilation branch pipe 22 is connected to the interface of the heat absorption cover 1, and the other end of the multiple ventilation branch pipes 22 is connected to one end of the ventilation main pipe 21. The other end of the ventilation main pipe 21 is connected to the air inlet of the exhaust device 3. Its structure is simple and makes the pipeline layout in the entire distribution room reasonable.

[0031] The ventilation main pipe 21 and the ventilation branch pipe 22 in the above technical solution are both PVC pipes, which have a simple structure.

[0032] See Figure 1 and Figure 3 As shown, the ventilation main pipe 21 in the above technical solution is provided with a reverse wind damper 23 (which may be similar to the structure disclosed in document number CN211667839U "Anti-reverse wind exhaust pipe and gas water heater"), so as to prevent the external airflow from flowing back into the power equipment through the heat dissipation assembly of the power equipment in the distribution room during windy and rainy weather.

[0033] The heat absorbing cover 1 in the above technical solution is trumpet-shaped, with a smaller opening end serving as its interface and a larger opening end communicating with the heat dissipation window 51 of the corresponding power equipment 5, and has a simple structure.

[0034] See Figure 4 As shown, the exhaust device 3 in the above technical solution includes a shell 31, a protective net 32 ​​and a fan 33. The shell 31 is a trumpet-shaped shell. The protective net 32 ​​is arranged at the larger opening end of the shell 31. The smaller opening end of the shell 31 is an air inlet. The fan 33 is arranged in the shell 31, and is used for blowing air outward through the larger opening end of the shell 31. The structure is simple, and the whole exhaust device has a good operating effect and low power consumption.

[0035] For further details, see Figure 4 In the above technical solution, a plurality of fans 33 are provided, and the plurality of fans 33 are all provided in the housing 31, and the plurality of fans 33 are distributed in an array in the housing 31, so that the exhaust volume of the exhaust device is large and the power consumption is low.

[0036] Example 2

[0037] like Figure 1 and Figure 3As shown, the same as Example 1, the difference is that the exhaust device 3 in the above technical solution is an axial flow fan, so that the exhaust volume of the entire exhaust device is large and the structure is compact. The air inlet of the exhaust device in this embodiment can be trumpet-shaped to be connected to the corresponding end of the ventilation main pipe.

[0038] The power distribution room power equipment heat dissipation assembly provided in Examples 1 and 2 of the utility model can directly extract the heat dissipated in the power equipment during operation, without having to wait for the heat to radiate into the distribution room and then cool the distribution room. This allows the entire power distribution room power equipment heat dissipation assembly to have good heat dissipation effect and low power consumption during operation. In addition, the use of the power distribution room power equipment heat dissipation assembly ultimately makes the temperature of the distribution room in summer equivalent to the outdoor temperature (so that the temperature inside the distribution room will not be too high).

[0039] The power equipment may be a transformer type equipment and / or a power cabinet type equipment, but is certainly not limited thereto.
