LoL: Is there a difference between Ranked Summoner names and Normal summoner names?

This is a really simple question but I was not able to find the answer to it. But is the name used in Ranked teams different from the Summoner name you use normally? I've seen team names in the Summoner name, but do people just change their names to that?

For example, my Summoner name is VirusThePanda, and my (Future) Ranked team is HCG. So would my name in Ranked become HCG VirusThePanda or do I need to actually change my Summoner name to that?
