Multiple use of dry ice in Formula 1 – Jalopnik

If you have ever looked at Formula 1 closely and we mean very closely you may have noticed that team members fill boxes of what looks like clear, smoked leaves. They are pushed into the Sidepoden, brake channels and cockpits of their cars, and all that dramatic smoke is not just for the show, although it looks cool. It is actually dry ice, and it is just as crucial a part of the toolkit of an F1 team as tire blankets.

Dry ice is carbon dioxide in solid form, sitting on a bone -chilling -109.3 degrees Fahrenheit. It does not melt in liquid such as ice water-in place it sublimizes it directly in gas, making it perfect for cooling powerful components without leaving moisture. That is the key if you are dealing with tightly packaged electronics, batteries and cockpits for driver who are not water -friendly.

In the High-Stakes World of F1, to which every tenth of a second one relates, the management of temperatures is just as important as managing horsepower. Dry ice is a controlled way to combat heat, thermal runaway and overheating while the car is stationary. Whether the car is between practice rounds, racing starts, in the pit lane or during a red flag delay, teams do not want vital systems to schedule themselves.

Of course, brake cooling is the most obvious use case. After all, those carbon-ceramic discs and pads become super hot to 1,832 degrees Fahrenheit during a round, and have no way to cool themselves outside the air flow. Teams have to bring their temperature back down before they on fire, and they do this with the help of dry -ice cooling fans as soon as the cars enter the pit garage. However, that is far from the only application of dry ice that you will see in F1.

During qualifying and racing preparation, dry ice is filled in radiators and can be seen from dropout when the driver is hard for the first time. It is even blown into the Sidepoden to reduce the temperatures of hybrid systems such as the MGU-K (Motors-unit-unit kinetic) and MGU-H (motorsian unit-heat). In 2018, Ferrari had everyone talking by throwing bright yellow dry ice creams over the cameras of their cars. It was officially to keep the electronics cool on the grid, but rival teams and the FIA did not bought it. In the midst of whispers of sneaky cooling tricks and airflow games, the FIA eventually entered and told Ferrari to cut it out.

You would think that in the F1 hypertech world there would be a solution for space age to cool before the race, such as liquid nitrogen or chic cryo fluids, but dry ice works for a few simple reasons. These include the fact that it is effective without being overly complicated, it does not introduce liquid in sensitive areas and its cooling effect is immediately and predictable.

Cockpit temps in Formula 1 can hit a burning 140 degrees Fahrenheit during the heterrival races. Fire racing suits make things worse for the coolers’ cooling needs and they do not get the luxury of air conditioning in an F1 car. So when they are in the garage, teams become creative. You will often see long channels or air tubes swinging the ceiling, cooled air activated by dry ice.

McLaren has put a special dry ice cream container in the nose of the car. The gas from the sublimating CO₂ is pumped by the cockpit until just before the light comes out, when the unit is pulled out and the nose is put together again. They also have the bottom of the chair and the floor gold foils to bend heat, thanks to an arrangement that blocks the front skid blocks harder than the back, which boils the floor directly under the driver.

Some teams package before the race dry ice ventilation openings or cool boxes in the cockpit. The Aleda company makes isolated boxes called Movitherm, while BOC offers advanced cooling systems are often seen in action. Some teams even use dry ice to cool the air in helmets and suits.

Formula 1 dives deep into small technology to convert them into large winnings, as seen with the apparently insignificant blinking red light on the back of F1 cars. In the same spirit, dry ice may seem like little more than a cool party trick but in a sport where warmth can succeed both machines and spirits, Droogijs becomes an essential survival equipment of the racing days.
