It is really hard to tell from the pics but it appears the air intake hose is to the engine air intake so it won't provide any cooling to the compartment. For cooling there has to be a cool air intake, preferably at the bottom, and a hot air outlet, preferably at the top. My cooling air outlet is at the bottom (I really don't have much choice) but since I'm installing a 326 CFM. 0.95 amp squirrel cage blower that takes in bottom cooling air ahead of the exhaust it should work fine.The sizes of a couple of blowers posted here amaze me, they are truly large enough to lift the bus!!
