Technical Field

[0001] The utility model belongs to the technical field of output filter coolers, and particularly relates to a cooling device for an output filter of a mine explosion-proof transformer. Background Technique

[0002] The output filter is installed between the power output line of the mine explosion-proof transformer and the motor. It can not only effectively filter out the high-order harmonics in the output current of the frequency converter, reduce the additional torque caused by the high-frequency harmonics, lower the motor temperature rise and the motor running noise, but also effectively suppress the surge voltage on the output side of the frequency converter, protect the motor, and improve the power factor of the variable frequency speed regulation system.

[0003] If the filter cannot dissipate heat for a long time during use, it may cause the temperature to exceed the normal range, resulting in component damage or inability to use. Therefore, its heat dissipation performance and ventilation conditions should be considered, and it should be avoided to use it under high temperature for a long time. Therefore, it is necessary to design a cooling device for the output filter of the mine explosion-proof transformer, which uses three combined ways of air cooling, water cooling and heat sinks to effectively cool the output filter used for a long time.

Mounting plates 15 are welded to both sides of the top of the output filter 1, and a protective shell 16 is snap-connected between the two mounting plates 15. A plurality of heat dissipation grooves are provided on the top of the protective shell 16.

[0024] Embodiment 2:

[0025] Figures 1-4A temperature reduction device for the output filter of a mine explosion-proof transformer, showing an embodiment of the present utility model, which includes an aluminum heat dissipation member 2 provided on the top of the output filter 1: The aluminum heat dissipation member 2 includes a heat-conducting metal block placed on the top of the output filter 1, and a plurality of heat dissipation fins are welded to the top of the heat-conducting metal block. Two fixing bars 3 are welded to the top of the output filter 1. Sliding sleeves 4 are welded to the bottoms of both sides of the aluminum heat dissipation member 2 and are slidably connected to the surface of the fixing bar 3. The fixing bar 3 is a T-shaped bar, and the inner cavity of the sliding sleeve 4 is a T-shaped groove. A heat dissipation fan 8 is snap-connected to the top of the aluminum heat dissipation member 2. A heat-conducting head 9 is fixedly installed on the left side of the top of the output filter 1 through a plurality of first screws. A cold head 10 is fixedly installed on the right side of the top of the output filter 1 through a plurality of second screws. The water outlet end of the cold head 10 is communicated with a long pipe 11 connected to the water inlet end of the heat-conducting head 9. A water pump 12 is fixedly installed on the top of the output filter 1 and is provided on the right side of the aluminum heat dissipation member 2. The water inlet end of the water pump 12 is communicated with a water inlet pipe 13 connected to the water outlet end of the heat-conducting head 9. Both the long pipe 11 and the water inlet pipe 13 are arranged inside the aluminum heat dissipation member 2. The water outlet end of the water pump 12 is communicated with a water outlet pipe 14 connected to the water inlet end of the cold head 10.

[0026] Working principle: When the present utility model is in use, the user slides the aluminum heat dissipation member 2 from front to back on the top of the output filter that has been installed between the power output line of the mine explosion-proof transformer and the motor for a long time, so that the sliding sleeve 4 slides on the surface of the fixing bar 3 until the rear side of the sliding sleeve 4 fits against the front side of 55. At this time, the positioning pin 6 is rotatably connected in the inner cavity of the threaded hole 7 so that the rear side of the positioning pin 6 fits against the front side of the sliding sleeve 4. At this time, the aluminum heat dissipation member 2 is limited on the top of the output filter 1. Subsequently, the long pipe 11 and the water inlet pipe 13 are passed through the inner cavity of the aluminum heat dissipation member 2 in sequence. Then, as shown by the user Figure 2 The long pipe 11, the water inlet pipe 13 and the water outlet pipe 14 are installed at the water inlet and outlet ends of the heat-conducting head 9, the cold head 10 and the water pump 12. The above installation method is a prior art means, so no more elaboration is made. When the output filter 1 is used for a long time, the aluminum heat dissipation member 2 will conduct out the temperature of the output filter 1. The operation of the heat dissipation fan 8 will blow the heat of the output filter 1 to the top of the protective shell 16. When the water pump 12, the heat-conducting head 9 and the cold head 10 are operating, the heat-conducting head 9 conducts the heat to the liquid in the water inlet pipe 13, and then enters the inner cavity of the cold head 10 through the water outlet pipe 14 under the operation of the water pump 12 and is cooled. When the water inlet pipe 13 passes through the inner cavity of the aluminum heat dissipation member 2, part of the heat will also be conducted away. Then the liquid will enter the inner cavity of the heat-conducting head 9 again through the inner cavity of the long pipe 11 to complete the cycle. The first heat dissipation is completed through the aluminum heat dissipation member 2, the second heat dissipation is completed through the heat dissipation fan 8, and the third heat dissipation is completed through the heat-conducting head 9, the cold head 10, the long pipe 11, the water pump 12, the water inlet pipe 13 and the water outlet pipe 14, so as to effectively achieve the purpose of cooling the output filter used for a long time.

[0027] In summary, for the temperature reduction device of the output filter of the mine explosion-proof transformer, through the setting of the aluminum heat dissipation part 2, the high temperature generated by the output filter 1 can be conducted and dissipated. Through the setting of the cooling fan 8, the temperature generated by the output filter 1 can be cooled by air. Through the combined use of the heat conduction head 9, the cold head 10, the long tube 11, the water pump 12, the water inlet pipe 13 and the water outlet pipe 14, the high temperature generated by the output filter 1 can be cooled by water, thus effectively achieving the purpose of cooling the output filter during long-term use.
