Any freezer engineers online?

I'm defrosting my fridge freezer cos there is loads of ice built up behind the freezer back panel, and there is a bit of polystyrene on the element (evaporator?) which is soaked and has split in two.

Do I need to put this back? Can't think what it actually does, but it must be doing something I guess...
