Everyone uses them, but maybe not everyone knows how New Line radiators are made and how they function. They are handmade with painstaking attention to detail. So, let’s briefly review the process, starting with the basics:

• • Why is it necessary to cool the engine?
    All combustion engines perform a given cycle of operation that produces heat. 2-stroke engines, for example, have 2 phases. To “control” the excessive heat that an engine produces it is necessary to have a tool that cools it and always maintains it at a temperature not higher than 60ºC and not lower than 45ºC: a radiator, precisely.

• •  How is a radiator constructed?
    Looking at it, a New Line radiator has a “face” characterised by grates. But they are grates that have been studied in every detail.

    The radiant masses arrive as raw materials: they are composed of a section tubes that form rods, crossed by some aluminium coils. After they have undergone heat treatment, until they release heat more quickly, they are frayed to ensure that the air has as much friction as possible. It is important for the air to cover the radiator properly to assist the operation of cooling water that flows through the radiant masses. The sides, to which hooks are attached to support the radiator, are made of aluminium. The trays are instead the top and bottom of the radiator and they are handmade.
    All parts of the radiator are then assembled and tested to avoid any micro porosity that would decrease efficiency.

• How a radiator works
  A radiator uses air and water for its engine cylinder cooling process. Here’s how.

  The water, which is in a first container at the top right of the radiator, enters the radiator. Subsequently it falls, thus undergoing an initial cooling process: in fact, it crosses the thick fins that serve to increase the heat exchange surface. In other words, this means that, thanks to these fins, the water takes a longer route along the radiator, thus being in contact with the air, which covers the radiator for more time. The result is greater cooling (in fact, for running in winter there is a “curtain” that covers part of the radiator and prevents the water from cooling it down too much).
  The water, thus cooled, is deposited in a second tray in the lower part of the radiator and moves towards the pump. Subsequently, entering from the lower part of the engine, it cools the cylinder, preventing it from overheating too. The water, which is now warmer, leaves the head of the engine and goes back into the first tray at the top right corner of the radiator, ready to start a new cooling cycle.
