The partition 350 divides the inside of the ventilation chamber 390 into a plurality of air paths 370, and the fans 320 are disposed in the air paths 370 in a one-to-one correspondence. Therefore, when the fans 320 operate simultaneously, the air driven by each fan 320 flows in the corresponding air duct 370 independently, so as to avoid the problem of hot air turbulence caused by the simultaneous operation of the fans 320, reduce the wind resistance caused by the turbulent flow of wind, improve the effective heat dissipation power, and ensure the safe operation of the transformer.

Specifically, the air inlets 310 are multiple, and the multiple air inlets 310 are disposed in the air duct 370 in a one-to-one correspondence.

In some embodiments, referring to fig. 3, the heat exchange member 400 is a fin group, the fin group is disposed in the wind collecting cavity 340, and one side of the fin group is located at the wind outlet 315. The fin group can carry out large-area heat dissipation on flowing air, so that the heat in the flowing air is ensured to be discharged in time.

Of course, the heat exchanging element 400 may also be other elements, such as a heat dissipating water discharge (not shown), and the specific implementation manner may be adjusted accordingly according to the actual situation, which is not limited herein.

The crimping may increase the contact area between the spacer 350 and the inner wall of the ventilation chamber 390 to facilitate the connection between the spacer 350 and the inner wall of the ventilation chamber 390. And, the increase of the contact area also increases the force receiving and applying area between the partition 350 and the inner wall of the ventilation chamber 390, so that the stability of the connection between the partition 350 and the inner wall of the ventilation chamber 390 can be increased.

Specifically, the inner wall of the ventilation cavity 390 is provided with a reinforcing strip 345, one of the two flanges is fixed on the reinforcing strip 345 by a screw, and the other flange is fixed on the closing plate 210 by a screw.

The connection plate 380 is used for connecting with a transformer, or a cabinet 900 for mounting the transformer. The wind shielding structure can shield the gap between the sealing plate 210 and the connecting plate 380, so as to prevent the flowing air from circulating outside the ventilation cavity 390, and further ensure the circulating heat dissipation of the flowing air in the ventilation cavity 390.

In some embodiments, referring to FIG. 5, a plurality of ribs 335 are disposed within the division bar 330. The division bars 330 need to withstand wind force frequently. The ribs 335 add strength to the spacers 330 to ensure that the spacers 330 do not deform under force and cause failure of the seal between the attachment plate 380 and the closure plate 210.

In certain embodiments, referring to fig. 1, a transformer includes a heat sink according to the above embodiments. The partition 350 divides the inside of the ventilation chamber 390 into a plurality of air paths 370, and the fans 320 are disposed in the air paths 370 in a one-to-one correspondence. Therefore, when the fans 320 operate simultaneously, the air driven by each fan 320 flows in the corresponding air duct 370 independently, so as to avoid the problem of hot air turbulence caused by the simultaneous operation of the fans 320, reduce the wind resistance caused by the turbulent flow of wind, improve the effective heat dissipation power, and ensure the safe operation of the transformer.

In some embodiments, referring to fig. 1, the transformer further includes a cabinet 900, a partition board 920 is disposed in the cabinet 900, and the air inlet 310 and the air outlet 315 are respectively located at two sides of the partition board 920. The partition plate 920 is provided with a ventilation column 930, and the ventilation member is installed in the ventilation column 930. When the fan 320 is started, the air on the lower side of the isolation plate 920 is driven to pass through the ventilation column 930 to form flowing air flowing to the upper side of the isolation plate 920 and take away heat on the energized components in the ventilation column 930. Subsequently, the flowing air flows into the ventilation chamber 390 from the intake vent 310, and the heat of the flowing air is removed by the heat exchange member 400. Subsequently, the cooled flowing air flows to the lower side of the partition 920 again and the heat dissipation work is completed.
