Description

Technical Field

[0001] The utility model relates to the technical field of source filters, in particular to a source filter heat dissipation structure. Background Art

[0002] Active power filter is a new type of special equipment for power harmonic control made by modern power electronics technology and digital signal processing technology based on high-speed DSP devices. It consists of two main parts: command current operation circuit and compensation current generation circuit.

[0003] The existing active power filters on the market currently have poor heat dissipation function. Long-term use will cause damage to internal electronic components due to high temperature. When using a box-type radiator to assist in heat dissipation, it is necessary to open multiple sets of ventilation windows on the box-type radiator so that ventilation and heat dissipation can be achieved. However, when used in a relatively closed space, the air flow rate is slow, which will affect the heat dissipation effect of the box-type radiator. For this reason, we propose an active filter heat dissipation structure. Utility Model Content

After the two first pulleys 7 rotate, the second pulley 10 and the third pulley 11 at both ends are driven to rotate synchronously through the synchronous belt. After the second pulley 10 and the third pulley 11 rotate simultaneously, the fan blades 12 on both sides of the bottom of the support frame 5 will be driven to rotate at high speed. After the two fan blades 12 rotate, the external fresh air will enter from the air inlet 20, and then enter the inside of the box body 1 along the air duct to dissipate the heat of the source filter body 24, and finally be discharged from the exhaust port 22, so that the heat dissipation can be carried out through circulating ventilation.

[0027] like Figure 2 and Figure 3 As shown, a fixing plate 13 is fixedly installed on the top of the inner part of the heat dissipation cover 2, and stainless steel dust-proof nets 14 are arranged at both ends of the fixing plate 13 near the second pulley 10 and the third pulley 11, and a connecting rod 15 is fixedly installed on the top of the second pulley 10 and the third pulley 11, and a first fixing bar 16 and a second fixing bar 17 are arranged on the top and bottom of the connecting rod 15 near the fixing plate 13, respectively, and soft brushes 18 are arranged on the first fixing bar 16 and the second fixing bar 17 near the stainless steel dust-proof net 14;

[0035] Working principle: When working, start the motor 6 inside the heat dissipation cover 2. After the motor 6 is started, it drives the two first pulleys 7 to rotate simultaneously. After the two first pulleys 7 rotate, they drive the second pulley 10 and the third pulley 11 at both ends to rotate synchronously through the synchronous belt. After the second pulley 10 and the third pulley 11 rotate simultaneously, they will drive the fan blades 12 on both sides of the bottom of the support frame 5 to rotate at high speed. After the two fan blades 12 rotate, the external fresh air will enter from the air inlet 20, and then enter the inside of the box 1 along the air duct to dissipate the heat of the source filter body 24, and finally exhaust air from the exhaust port 24. The air is discharged through the air inlet 22. During ventilation and heat dissipation, external dust will be sucked in from the position of the air inlet 20 and then cover the stainless steel dustproof nets 14 at both ends of the fixing plate 13. When the second pulley 10 and the third pulley 11 rotate at the same time, the connecting rod 15 at the top will be driven to rotate synchronously. After the connecting rod 15 rotates, it will drive the first fixing bars 16 at the top and bottom to rotate.
