Air conditioning in the tank

There is such a scene in the TV series “North African Desert Action”: a German tank anchored in the desert, British soldiers blocked all the vents on the tank with palm leaves, and the German soldiers who suffered from the high temperature in the car had to surrender. Similar situations have occurred on the battlefields in the Middle East: the intact tanks have been abandoned on the way. It is highly probable that the tanker would rather abandon the car and run away from the “oven”.

How can we both be “demeanor” and combat strength? Why can’t I put air conditioners directly on tens of millions of tanks? It turns out that air conditioners are not only big, but also “large energy consumers”, which will take away engine power and increase fuel consumption, which will cause great damage to the maneuverability of the tank. When the air conditioner works, it will dissipate heat, which will increase the infrared characteristics of the tank, making it easier to expose on the battlefield. In addition, the air conditioning system is not as thick and thick as a tank, and it is easy to absorb dust and sand in the field and cause damage.

Air conditioning involves the rational allocation of limited space in the tank, and special efforts must be made at the beginning of the design. In the subsequent improved version of the “Leopard 2” series of tanks, the turret is getting bigger and bigger, one of the important reasons is to install air conditioning components at the rear of the turret.

However, the primary purpose of air conditioning for tanks is not to “cool down” the maddening tankers, but to cool the electronics inside the car. All kinds of optoelectronic equipment on the tank are very “petty”, and they encounter “high strike” when they encounter high temperatures. Therefore, the US M1A2, Russia’s T-80Y, Britain’s “Challenger II”, France’s “Leclerc” and other tanks have been installed air-conditioning.
