Mounting plate 11, mounting cylinder 12 and mounting flange 13 and above-mentioned patent are essentially identical, the difference is that a cover board is arranged in this implementation
14, which can be connect by bolt with mounting flange 13 inverter to be fixed in mounting cylinder 12, as mounting plate 11
On mounting post and mounting hole can implement in the way of above-mentioned patent, the present embodiment is not described in detail.Wherein, cover board 14 can be set
Heat release hole is set, the heat that inverter generates directly is distributed into air.
Connection ring 20 its in a ring and coaxial arrangement in mounting plate 11 far from 12 side of mounting cylinder, with mounting flange 13
Shape, size are roughly the same, can be convenient for connecting with the air inlet of the wind scooper of variable-frequency power generation unit, specifically can be in connection ring 20
Upper setting connecting hole, in order to be bolted.
Radiating subassembly 30 includes a heat dissipating ring 31, multiple first heat sinks 32 and multiple second heat sinks 33, the heat dissipation
31 one end of ring is coaxially connected to be extended to and 20 side of connection ring in opposite 20 side of connection ring of the mounting plate 11, the other end
End face is concordant, and avoidable heat dissipating ring 31 protrudes from connection ring 20 and enters in the wind scooper of variable-frequency power generation unit, guarantee and frequency conversion
The agreeing with property of the wind scooper connection of generating set；Multiple first heat sinks 32 and the second heat sink 33 are both secured to mounting plate
11 opposite 31 sides of heat dissipating ring are simultaneously evenly arranged along circumferential successively replace of heat dissipating ring 31, and each first heat sink
32 and second heat sink 33 be arranged radially along the heat dissipating ring 31, due under the action of wind scooper, air-flow is first along heat dissipation
Ring 31 is radially into then again along it axially into wind scooper, and the first heat sink 32 and the second heat sink 33 are along heat dissipating ring 31
Radial direction arrangement is then conducive to air-flow and enters, and guarantees air-flow air intake efficiency, and multiple first heat sinks 32 and the second heat sink 33 are along scattered
