There was someone who used a wire shelf table and they put a portable cooler under it pointing to the lower right of the forge.
Others have fabricated igloo type boxes around it to keep cooling in area.
Like the wire shelf idea. Looked sound and did not seem like a total hack. Cannot find the link though - sorry.
here is one of the boxes
