It puts the fan in cooler bin, forms cold air in the cooler bin, the cold air in the cooler bin is by fan to transformation
Device winding radiates, and Turbogrid plates, the cooler bin are set as positioned at the upper surface of the cooler bin of the transformer winding bottom
Upper surface is additionally provided with sieve tray, and the sieve tray is regular polygon shape, and the sieve tray is cold between transformer winding
But case upper surface is vertically arranged with more cooling tubes positioned at the sieve pore of the sieve tray center line, and the cooling tube forms multiple
Small ventilating holes.
In above-mentioned technical proposal setting provide cold air cooler bin, and by fan convey cold air to transformer around
The bottom of group is carried out to the heat dissipation of the radial direction of transformer winding, at the same set sieve tray by cooling air be sent into screen holes and with it is a
In the cooling tube being connected of other screen holes, the heat dissipation between adjacent transformers winding is realized, and realize transformer winding
Middle part and the heat dissipation at top, the small ventilating holes having on cooling tube in addition realize axial heat dissipation, and effect is more previous to be dissipated
Hot mode is more excellent.
The utility model further sets the sieve tray to include the first sieve tray, the second sieve tray, third sieve tray, the
The cooling tube of four sieve trays, the small ventilating holes of the cooling tube set on first sieve tray and the setting of the second sieve tray it is ventilative
Aperture is oppositely arranged, the cooling tube of the small ventilating holes of the cooling tube set on the third sieve tray and the setting of the 4th sieve tray
Small ventilating holes are oppositely arranged.
In above-mentioned technical proposal, the first sieve tray and the second sieve tray and cooled down with third sieve tray and third sieve tray
The small ventilating holes of pipe, which are oppositely arranged, ensure that the flowing of axial upper air improves the effect of heat dissipation.
The utility model further sets the cooling tube direction set on sieve tray described in same consistent, i.e. small ventilating holes
Positioned at the same side.
Ensure good heat dissipation effect towards consistent in above-mentioned technical proposal.
The utility model further sets and gas port is provided on the upper clamping piece, and the gas port is located on cooling tube
Side, the gas port are set as ellipse.
Gas port is set in upper clamping piece in above-mentioned technical proposal, realizes that the further heat at top is eliminated.
The utility model further sets the sieve tray to be set as regular hexagon.Set regular hexagon beautiful.
