[0002] The frequency converter is mainly used to adjust the operating frequency of the equipment, reduce energy loss, start the equipment smoothly, and reduce the damage to the motor caused by the large current generated when the equipment is directly started. Since the frequency converter is usually installed in the control box, a large amount of heat will be generated during its operation, which will increase the temperature inside the box. If the heat is not dissipated in time, the long-term operation of the equipment at high temperature may affect its operating effect and service life. At present, in order to dissipate heat, ventilation holes are usually opened on the box for natural ventilation and heat dissipation. However, this heat dissipation efficiency is low, and dust can easily enter the box through the holes and contaminate the electronic components. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The dustproof electrical frequency conversion controller component is provided with a water pump, a delivery pipe, a connecting pipe, a cooling pipe, a heat conducting plate and a fan. The water pump is started to extract the coolant in the liquid storage tank and transport it to the cooling pipe through the delivery pipe.

Then, the connecting strip is pushed into the connecting groove, so that the mounting frame can be fixedly installed on both sides of the box body, and the dustproof screen can block the vents, thereby preventing dust from entering the box body from the vents and preventing dust from contaminating electronic components.

DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-5 As shown, the utility model provides a technical solution: a dustproof electrical frequency conversion controller component, including a box body 1, a box door 2 is rotatably connected to the front of the box body 1, vents 3 are opened on both sides of the box body 1, and connecting grooves 18 are opened at the positions where the vents 3 are opened on both sides of the box body 1, and the connecting strip 13 is T-shaped and is slidably connected to the connecting groove 18. The sliding of the connecting strip 13 in the connecting groove 18 can assist the staff to position and install the installation frame 4, so that the dustproof mesh plate 15 blocks the vent 3 to prevent dust from entering the box body 1 from the vent 3.

[0022] Installation frames 4 are slidably installed on both sides of the box body 1, a liquid storage tank 5 is installed under the box body 1, a cooling pipe 6 is installed on the inner wall of the box body 1, an observation window 22 is installed on the box door 2, support legs 23 are connected to the four corners below the box body 1, and anti-slip pads 24 are connected below the support legs 23. The box body 1 is supported by the support legs 23, and the anti-slip pads 24 can increase the friction between the support legs 23 and the ground, thereby preventing the support legs 23 from sliding.

[0023] A heat conducting plate 7 is connected through the top of the box body 1, and a shell 8 is connected to the top of the box body 1. A fan 9 is installed on one side of the shell 8. The cooling pipe 6 passes through the heat conducting plate 7. A through hole 20 is opened on the heat conducting plate 7. Ventilation gaps 21 are arranged on both sides of the shell 8. The through holes 20 increase the contact area between the heat conducting plate 7 and the air, thereby improving the heat dissipation efficiency of the heat conducting plate 7, and the ventilation gaps 21 can ensure the normal circulation of air in the shell 8 to avoid the accumulation of high-temperature air.

[0024] A water pump 10 is connected to the bottom of the box body 1, a delivery pipe 11 is connected to one side of the water pump 10, a connecting pipe 12 is connected to the liquid storage tank 5, the water pump 10 is connected to the liquid storage tank 5 through a connecting water pipe, and the cooling pipe 6 is distributed on the inner wall of the box body 1 in a serpentine shape, one end of the cooling pipe 6 is connected to the delivery pipe 11, and the other end of the cooling pipe 6 is connected to the connecting pipe 12. The coolant is made to flow evenly through various positions of the box body 1 through the serpentine cooling pipe 6, thereby evenly absorbing the heat in the box body 1, and the coolant will eventually flow back into the liquid storage tank 5 through the connecting pipe 12, thereby realizing the recycling of the coolant.

[0025] Connecting strips 13 are connected to the installation frame 4 on both sides, and a plug rod 14 is connected to the installation frame 4. A dustproof mesh plate 15 is plugged into the plug rod 14. A plug hole 16 is provided on the dustproof mesh plate 15. A notch groove 17 is provided on the dustproof mesh plate 15. A protrusion 19 is connected to one end of the plug rod 14. The protrusion 19 is made of rubber and has a spherical design. The plug rod 14 is plugged into the plug hole 16. The dustproof mesh plate 15 is fixed by the rubber protrusion 19, so that the staff can remove the dustproof mesh plate 15 quickly and conveniently, so as to clean the dustproof mesh plate 15 in time to prevent dust from clogging the dustproof mesh plate 15 and affecting ventilation.

[0026] The working principle of the utility model is:

[0027] The staff inserts the plug rod 14 into the socket 16. As the plug rod 14 is inserted, the protrusion 19 is squeezed and deformed by the dust screen 15, so that the protrusion 19 recovers its shape after the plug rod 14 passes through the socket 16, fixes the dust screen 15 on the installation frame 4, and then pushes the connecting strip 13 into the connecting groove 18, fixes the installation frame 4 on both sides of the box body 1, so that the dust screen 15 can block the vent 3 to prevent dust from entering the box body 1 from the vent 3 and contaminating the electronic components. The pump 10 will extract the coolant in the liquid storage tank 5 and transport it to the cooling pipe 6 through the delivery pipe 11. The serpentine cooling pipe 6 allows the coolant to flow evenly through various positions of the box body 1, thereby evenly absorbing the heat in the box body 1. When the coolant flows through the heat conducting plate 7, the heat conducting plate 7 will absorb the heat of the coolant, and at the same time, the fan 9 will blow air to the heat conducting plate 7, thereby accelerating the heat dissipation rate on the heat conducting plate 7, thereby reducing the temperature of the coolant. After that, the coolant will flow back into the liquid storage tank 5 through the connecting pipe 12.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
