Detailed Description

The invention is described in further detail below with reference to the figures and the embodiments.

As shown in fig. 1 to 5, an electrical equipment heat dissipation device comprises a housing 1, a plurality of heat dissipation fins 2 are arranged on the outer wall of the housing 1, a mounting base 3 is arranged at the top of the housing 1, the bottom of the mounting base 3 is connected with the housing 1 through a plurality of mounting rods 4, a connecting rod 6 is arranged between the mounting base 3 and the housing 1, two ends of the connecting rod 6 are respectively connected with the mounting base 3 and the housing 1 through bearings 5, a plurality of fan blades 7 are arranged on the connecting rod 6, and a vent pipe 8 is further arranged at the bottom of the housing 1.

Preferably, the fan blade 7 is of a hollow structure. Such setting has lightened the weight of flabellum 7, and flabellum 7 specifically adopts the PVC material in this embodiment, and low cost, weight are lighter, have reduced the required wind-force of flabellum 7 rotation to practice thrift energy consumption, dispel the heat for casing 1 better.

Preferably, an anti-corrosion coating is arranged outside the connecting rod 6 and the fan blades 7. Due to the arrangement, the corrosion of the external environment to the connecting rod 6 and the fan blade 7 is reduced, and the service lives of the connecting rod 6 and the fan blade 7 are prolonged.

Preferably, the inner side of the vent pipe 8 is provided with threads, the inner threads of the vent pipe 8 are sleeved with the dehumidifying pipe 9, and the dehumidifying pipe 9 is internally provided with a moisture absorption layer 10. In this embodiment, the moisture absorption layer 10 is made of moisture absorption cotton, which is low in cost and convenient to replace. Through the arrangement of the dehumidification pipe 9 and the moisture absorption layer 10, the air pressure in the shell 1 can be kept balanced, and meanwhile, moisture in the air can be filtered, so that the condition that components in the shell 1 are damaged due to contact with the moisture is avoided.

Preferably, a mounting groove 11 is opened on a side wall of the housing 1, and a louver 12 is fixed inside the mounting groove 11. This arrangement enables heat to be dissipated from the inside of the housing 1 while preventing moisture from entering the inside of the housing 1.

Preferably, a through groove 13 is formed at the top of the housing 1, and a rotary shaft sealing ring 14 matched with the connecting rod 6 is arranged inside the through groove 13. Such an arrangement enables sealing between the through slot 13 and the connecting rod 6 without interfering with rotation of the connecting rod 6.

The working principle of the embodiment is as follows: when using, when flabellum 7 receives the wind speed of flowing to drive, can drive connecting rod 6 because bearing 5's cooperation rotates, connecting rod 6 rotates through leading to groove 13 and rotation axis sealing washer 14's cooperation, flabellum 7 has accelerated the air flow speed in the casing 1 when rotating, make flabellum 7 cool down in casing 1 through shutter 12 and permeability cell 8's cooperation, thereby accelerated the speed that the temperature reduces in the casing 1, thereby reached quick heat dissipation protection transformer, advantages such as reduction power consumption.

The utility model provides a current transformer dispel the heat through the fin and lead to the radiating effect poor and cause the situation of electric energy consumption big and transformer damage, this device when using, can effectively dispel the heat to the component in the casing 1 by the power of wind energy to reduced the electric energy consumption that the transformer caused because the high temperature when using, also reduced the situation that the transformer damaged because the high temperature simultaneously, be fit for using widely.
