Technical effects

Compared with the traditional structure of setting up air cooler, the utility model has the characteristics of it is following:

1. when the unit operates, the utility model discloses can make the internal circulation air current that is blown off by the rotating fan from left to right take away the generator heat after, all flow along the inner wall reverse of outer bulkhead, return to fan department again, form the circulation and flow, in this process, because the outer bulkhead outside is low temperature sea water, make the temperature of outer bulkhead far less than the internal circulation air current that carries the generator running heat, when the internal circulation air current flows along outer bulkhead, the heat in the air current will be absorbed by the outer bulkhead of lower temperature rapidly, thereby reach the purpose of rapid cooling internal circulation air current;

2. after the structure of the utility model is used, the tidal current energy generator set does not need to be internally provided with an air cooler, a large amount of space which is originally reserved for the air cooler is released, and the internal operation space is improved; meanwhile, an air cooler and a water inlet and outlet pipeline of cooling water are not needed, and a water pipe is not arranged in the tidal current energy generator, so that the risk of water leakage of the water pipe is avoided, and the running stability of the unit is improved.
