Description

Technical Field

[0001] The utility model relates to the technical field of converter heat dissipation, in particular to a heat dissipation shell for an energy-saving converter. Background Art

[0002] A converter is an electrical device that changes the voltage, frequency, number of phases and other electrical quantities or characteristics of a power supply system.

[0003] The inverter will emit a lot of heat during operation. The ordinary inverter casing only has multiple heat dissipation holes on the inner wall of the casing to dissipate the heat. However, these heat dissipation holes are like a drop in the bucket and are far from enough to dissipate the heat of the inverter. If the inverter continues to operate overheated for a long time, its service life will be reduced. Therefore, the inverter casing needs to be improved.

[0004] To this end, we propose an energy-saving heat dissipation housing for a converter. Utility Model Content

[0005] The main purpose of the utility model is to provide an energy-saving heat dissipation housing for an inverter. By arranging an exhaust fan box on the upper part of one side of the inverter housing, the interior of the inverter housing can be exhausted through the operation of the exhaust fan box, which can not only extract the heat generated by the operation of the inverter, but also generate negative pressure inside the inverter housing, thereby allowing the outside air to flow into the interior of the inverter housing through the heat dissipation holes to achieve cooling. The heat sink is then used to provide a heat dissipation effect on the back of the inverter housing, thereby extending the service life of the inverter. The problems in the background technology can be effectively solved.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A heat dissipation housing for an energy-saving converter comprises a converter housing, a ventilation pipe is fixedly plugged into the top of the converter housing, a support plate is fixedly installed on the upper part of one side of the converter housing, and a ventilation box is fixedly installed on the top of the support plate;

[0008] Both sides of the converter housing are provided with heat dissipation holes, and a plurality of heat dissipation holes are provided. Slots are provided inside the two sides of the converter housing, and the slots are used for installing and inserting the dustproof net.

[0009] Furthermore, the slot and the dustproof net are provided at two locations opposite to each other, the top ends of the dustproof nets at the two locations are fixedly connected to limit plates, and the bottom ends of the limit plates are in contact with the top of the converter housing.

[0010] Furthermore, an air collecting hood is fixedly installed on the inner top of the converter housing, one end of the exhaust pipe passes through the top of the converter housing and is fixedly connected and communicated with the top of the air collecting hood, and one end of the exhaust pipe away from the air collecting hood is fixedly plugged into the top of the exhaust chassis.

[0011] Furthermore, an air outlet duct is provided on a side of the exhaust fan chassis away from the converter housing, and a heat sink is fixedly mounted on one side of the converter housing just below the support plate.

[0012] Furthermore, one side of the converter housing is fixedly connected with anti-dumping support plates on both sides of the heat sink, the anti-dumping support plates are arranged in a triangular structure and are provided at two locations opposite to each other, and a door is movably installed on one side of the converter housing away from the heat sink.

[0013] Compared with the prior art, the utility model has the following beneficial effects: by arranging an exhaust fan box on the upper part of one side of the inverter housing, the interior of the inverter housing can be exhausted through the operation of the exhaust fan box, which can not only extract the heat generated by the operation of the inverter, but also generate negative pressure inside the inverter housing, thereby allowing the outside air to flow into the interior of the inverter housing through the heat dissipation holes to achieve cooling, and then cooperate with the heat sink to provide a heat dissipation effect on the back of the inverter housing, thereby extending the service life of the inverter.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1 , Figure 2 , Figure 3As shown, a heat dissipation housing for an energy-saving converter includes a converter housing 1, wherein a cavity is provided inside the converter housing 1 for installing and placing the converter inside, an exhaust pipe 8 is fixedly plugged into the top of the converter housing 1, a support plate 6 is fixedly installed on the upper part of one side of the converter housing 1, an exhaust fan box 7 is fixedly installed on the top of the support plate 6, and an exhaust fan is installed inside the exhaust fan box 7;

[0020] Both sides of the converter housing 1 are provided with heat dissipation holes 4, and the heat dissipation holes 4 are provided in multiple locations. Slots 10 are provided inside the two sides of the converter housing 1, and the slots 10 are used for installing and inserting the dustproof net 3. The setting of the dustproof net 3 can prevent dust in the outside air from entering the inside of the converter housing 1, and the dustproof net 3 can be disassembled, cleaned or replaced at any time, and the insertion port of the slot 10 is set at the top of the converter housing 1;

[0021] The slot 10 and the dustproof net 3 are arranged at two locations opposite to each other, and the top ends of the dustproof nets 3 at the two locations are fixedly connected to the limiting plates 9, and the bottom ends of the limiting plates 9 are in contact with the top of the converter housing 1. The setting of the limiting plates 9 prevents the dustproof net 3 from falling completely into the slot 10 and being unable to be taken out, and also facilitates the disassembly and replacement of the dustproof net 3; an air collecting hood 13 is fixedly installed on the inner top of the converter housing 1, and one end of the exhaust pipe 8 passes through the top of the converter housing 1 and is fixedly connected and communicated with the top of the air collecting hood 13. The function of the air collecting hood 13 is to concentrate the air in the converter housing 1 into the exhaust pipe 8, and one end of the exhaust pipe 8 away from the air collecting hood 13 is fixedly plugged into the top of the exhaust fan case 7, and one end of the exhaust pipe 8 away from the air collecting hood 13 passes through the top of the exhaust fan case 7 and is fixedly connected to the exhaust end of the internal exhaust fan;

[0022] An air outlet duct 12 is provided on the side of the exhaust fan case 7 away from the inverter housing 1, and the air outlet duct 12 is fixedly connected to the air outlet end of the exhaust fan inside the exhaust fan case 7. A heat sink 11 is fixedly installed on one side of the inverter housing 1 just below the support plate 6; anti-dumping support plates 5 are fixedly connected on both sides of the heat sink 11 on one side of the inverter housing 1, and the anti-dumping support plates 5 are arranged in a triangular structure and are provided at two locations opposite to each other. A fan door 2 is movably installed on the side of the inverter housing 1 away from the heat sink 11.

[0023] It should be noted that the utility model is an energy-saving heat dissipation housing for an inverter. When the inverter generates a large amount of heat during operation, the exhaust fan in the exhaust box 7 can be started by an external power supply. The start of the exhaust fan will extract most of the heat in the inverter housing 1 through the exhaust duct 8 and then discharge it through the outlet duct 12. In addition, the interior of the inverter housing 1 forms a negative pressure due to the large amount of air drawn by the exhaust duct 8, which causes the external cold air to flow into the interior of the inverter housing 1 from the heat dissipation holes 4, further providing heat dissipation for the inverter, and then cooperates with the heat sink 11 to provide a heat dissipation effect for the inverter inside the inverter housing 1, so that the temperature of the inverter will be reduced. The dustproof net 3 can be removed by pinching the limit plate 9 and pulling it upward to pull out the dustproof net 3.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
