Chasis A/C condenser - blocking air lfow to radiator?

I had some over heating issues while towing in 85 degree weather up hills recently. I've never heard my clutch fan kick in so I am replacing that and also the thermostat (it opens but a new one opens a bit more when I compared the two). Anyway, I know it's important to keep proper airflow through the radiator. While looking around it appears that I have a large A/C condenser that sits right in front of the radiator. The condenser has very thin blades with very tiny spaces. Much smaller than the radiators spaces. Also, in front of that sit's another cooler of some sort. I feel like the A/C condenser would have to reduce airflow through the radiator. Are there different condensers that would allow better airflow or should I not worry about it?
