Between be additionally provided with intermediate strengthening portion 43, but since air-flow is can to enter air inlet sky along perpendicular to the direction of perpendicular
Between 64, so admission space 64 between top interconnecting piece 41 and pedestal interconnecting piece 42 it is also assumed that be unlimited.From another party
For, if interconnecting piece 40 makes air-flow in one direction without forming the entity structure that continuously direction is completely covered
Admission space 64 cannot be entered along the direction and need to be considered as admission space along other directions around the entity structure
64 are unlimited in the direction.
