What are radiator panels and convection fins?

A radiator is made up of panels, the flat surfaces at the front and back of the radiator and convection fins which sit in between the panels.  

Radiators may have one or two panels and then one or two rows of thin zig zagging metal layers depending on the size and heat output of the radiator. The panel is the outside facing areas they are filled with fluid such as water or oil.  

The convection fins are the zig zagging layer of metal fins behind the radiator, they add a considerable amount of surface area for your metal tank, the more surface area the more heat that is pulled away from the radiator by air currents.
