Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-4, an air-cooled cooling device for transformer, including casing 1, the bottom fixedly connected with support 2 of casing 1, and the both sides of support 2 set up downwards, have certain difference in height under the middle of support 2 under terminal surface and both sides between the terminal surface, the top of casing 1 is provided with blade 6, there are a plurality ofly 6 annular arrays of blade, and the inside top of casing 1 is provided with fan 8, and through connecting axle 7 fixed connection between blade 6 and the fan 8, the top bolt fixedly connected with driving motor 10 of casing 1, and driving motor 10 passes through the transmission between chain mechanism 11 and the connecting axle 7 and is connected, chain mechanism 11 includes the chain, flywheel and toothed disc, toothed disc and driving motor 10's output shaft cover are established, the flywheel is located connecting axle 7, the chain is installed in the flywheel and the toothed disc outside, carry out the transmission to both.

Specifically, as shown in fig. 1 to 3, the top of the housing 1 is fixedly connected with a top cover 9, the top cover 9 is disposed on one side of the blade 6, the other side of the blade 6 is exposed outside the top cover 9, and the driving motor 10 is disposed inside the top cover 9, so that only half of the blade 6 can be in contact with the external air flow, and a better rotating effect is obtained.

Specifically, as shown in fig. 1, fig. 2 and fig. 4, through groove 101 has been seted up at equidistant on the vertical end wall of casing 1, and through groove 101 runs through casing 1 setting, fixedly connected with fin 3 on casing 1's the outer wall, and fin 3 is two segmentation structures, and have the clearance between two segments, the clearance corresponds the coincidence setting with through groove 101, thereby make fin 3 and casing 1's inside intercommunication, the heat effluvium of being convenient for, fixedly connected with separation blade 4 in fin 3's the clearance, and the contained angle is 10 settings between separation blade 4 and the casing 1, and separation blade 4's length is less than through groove 101 vertical height, separation blade 4 extends to one section distance of outside of fin 3, better rain-sheltering effect has, and there is a certain interval between the top of separation blade 4 and fin 3, the inside hot gas stream of being convenient for efflu.

Specifically, as shown in fig. 1, the bottom of the support 2 is fixedly connected with a plurality of bottom plates 5, the bottom plates 5 are arranged at equal intervals, and the height difference between the height of the bottom plate 5 and the height of the support 2 is the same, so that the bottom of the transformer can dissipate heat conveniently.
