THE FRONT AREA OF THE RADIATOR IS THE ONLY FACTOR THAT DETERMINES COOLING
A company specialised in the supply of cooling systems for motorsport.
Well done!

The frontal area of ​​the radiant mass is certainly a fundamental factor in thermal performance, but there are also other variables that can affect the dissipation of heat. In fact, the maximum possible heat dispersion can be affected both by the operating conditions of the radiator, i.e. the temperature and flow rate of the coolant, and by environmental factors, such as the air temperature, and, finally, by the different speeds that a kart reaches during its activity on the track. Therefore, there are many aspects to take into consideration to maximise the efficiency of a radiator in relation to the contingent conditions of use. A few examples? The geometry of the tubes and fins, the area of ​​the radiant mass and its thickness, the design of the trays and the flow path of the coolant (water for karts). All these factors, and the way in which they interact with each other, play an important role in the performance of the radiator (precisely on these aspects TKART has focused in the article “Technical track test – Kart radiators: with the same surface, how important is the type of radiant mass? “, editor’s note).
