  • Why do racers need the Alphacooler System to cool down?
  • How does a racer cool down when it’s 60 degrees inside?

In the realm of motorsports, the absence of air conditioning in race cars is a deliberate choice made to shed excess weight, a critical factor for optimizing power and maintaining efficient heat dissipation during races. This weight-saving measure is especially prevalent, with only a select few high-level GT models retaining the option for a specialized race air conditioning system.

The consequence of this weight-conscious decision becomes apparent in summer races when temperatures inside the car soar well beyond 60 degrees Celsius. This extreme environment poses significant challenges for drivers, leading to potential issues like impaired judgment, dizziness, and increased susceptibility to panic. Such adverse effects can significantly impact the overall driving experience, even elevating the risks of fainting or, worse, a potential crash.

In response to these challenges, Carlson Technologies took a pioneering step in 1978 by developing an ice suit. This innovation drew inspiration from the liquid-cooled helmets used by fighter pilots. By incorporating this technology, the racing community experienced a notable improvement in mitigating heat-related issues, with a reported 40% to 60% reduction in the heating problem.

However, this early solution had its drawbacks. The working time of the system was directly tied to the size of the incubator, with extended insulation time achieved by using more ice. Yet, once the ice melted, the effectiveness of the system diminished considerably. Additionally, the weight of the system, determined by the size of the incubator, posed a counterintuitive challenge. As the ice clothing system added significant weight to the car, it contradicted the broader efforts to reduce the overall weight and burden on the vehicle.

Recognizing the limitations of existing solutions, RIGID undertook a substantial three-year development process to introduce Alphacooler, a cutting-edge cold water system tailored specifically for racing conditions. Alphacooler successfully addressed the shortcomings of traditional ice suits by adopting a more advanced approach. Notably, it is smaller and lighter, weighing less than 6.8 kg. Instead of relying on traditional ice cooling methods, it employs a brushless DC inverter compressor, ensuring continuous and efficient refrigeration.

The Alphacooler system incorporates essential components such as a water tank and pump, offering the flexibility to use either pure water or biodegradable liquids, such as coolant. The ability to replace the coolant every three months enhances the system’s sustainability and adaptability. Furthermore, RIGID designed Alphacooler with a dedicated cooling suit, complete with a quick connector for simplified operation.

To enhance user convenience, the Alphacooler system is equipped with a remote control featuring a temperature controller. This feature enables drivers to adjust temperatures according to different weather conditions, ensuring optimal cooling for both the vehicle and the driver. By prioritizing heat dissipation, Alphacooler aims to safeguard consistent and top-tier performance, allowing drivers to maintain heightened concentration, faster reactions, and an overall more stable and enjoyable racing experience.
