a supporting platform comprising a body portion, the body portion comprising an inlet, a plurality of outlets, a flow channel communicating the inlet with the plurality of outlets, and a mounting position for mounting a functional device, the inlet, the plurality of outlets and the flow channel together forming a medium circulation passage, wherein the body portion comprises a main beam and a reinforcement beam, the main beam and the reinforcement beam intersect and connect with each other, the plurality of outlets are provided on the main beam and are arranged at intervals in an extending direction of the main beam, and a cross section of one of the end portions of the main beam in the extending direction has a decreasing tendency along the extending direction; and
a heat exchange apparatus which communicates with the medium circulation passage and delivers a cooling medium into the medium circulation passage, the cooling medium flowing through the inlet and the flow channel and flowing out of the outlet to exchange heat with the functional device.

2. The heat dissipation system according to claim 1 , wherein least one of the plurality of outlets is provided corresponding to the mounting position.

3. The heat dissipation system according to claim 1 , wherein the flow channel is arranged in a grid shape as a whole.

4. The heat dissipation system according to claim 1 , wherein:
at least part of the main beam and at least part of the reinforcement beam respectively comprise a hollow pipe which comprises the flow channel and communicate with each other, and the inlet and/or the plurality of outlets are provided on one of the main beam and the reinforcement beam which comprise the flow channel respectively.

5. The heat dissipation system according to claim 4 , wherein the main beam and the reinforcement beam are both made of closed box-type beams and communicate with each other.

6. The heat dissipation system according to claim 4 , wherein the supporting platform further comprises a connection portion, the connection portion is provided on the body portion, and the connection portion is a flange or a connection seat.

7. The heat dissipation system according to claim 1 , wherein the heat exchange apparatus comprises a heat exchanger and a cold end which communicate with each other through a pipeline, and the cold end is fixedly connected to the supporting platform.

8. The heat dissipation system according to claim 1 , wherein the cold end comprises a recovery medium driving portion which is capable of recovering, to the cold end, part or all of the cooling medium flowing out of the plurality of outlets to cool the cooling medium, and delivering the cooling medium after being cooled back to the medium circulation passage.

9. The heat dissipation system according to claim 1 , wherein the supporting platform further comprises a flow control component, and the flow control component is provided inside the flow channel to control a flow rate of the cooling medium in the flow channel.

10. A wind generator set, comprising:
a tower;
a nacelle provided at an end of the tower in an axial direction, the nacelle comprising a nacelle cover, a base and a functional device positioned inside the nacelle cover, the base being connected to the tower; and
the heat dissipation system according to claim 1 , the supporting platform being provided inside the nacelle cover and connected to the base,
wherein the functional device is mounted at the mounting position on the supporting platform.

11. The wind generator set according to claim 10 , wherein the functional device comprises at least one of an electrical device, a mechanical device, and a maintenance device, and a truss is further provided inside the nacelle cover, and the nacelle cover is connected to the supporting platform by the truss.

12. A supporting platform for use in conjunction with a heat exchange apparatus, the supporting platform comprising a body portion, the body portion comprising an inlet, a plurality of outlets, a flow channel communicating the inlet with the plurality of outlets, and a mounting position for mounting a functional device; the inlet, the plurality of outlets and the flow channel together forming a medium circulation passage, the medium circulation passage being connected to the heat exchange apparatus, and a cooling medium delivered by the heat exchange apparatus flowing through the inlet and the flow channel and flowing out of the plurality of outlets to exchange heat with the functional device, wherein the body portion comprises a main beam and a reinforcement beam, the main beam and the reinforcement beam intersect and connect with each other, the plurality of outlets are provided on the main beam and are arranged at intervals in an extending direction of the main beam, and a cross section of one of the end portions of the main beam in the extending direction has a decreasing tendency along the extending direction.

13. The supporting platform according to claim 12 , wherein the supporting platform further comprises a flow control component, and the flow control component is provided inside the flow channel to control a flow rate of the cooling medium in the flow channel.
