Description

Wheel heat abstractor Technical Field The utility model relates to the technical field of vehicle engineering, in particular to a wheel heat dissipation device. Background In the field of modern transportation, the performance and the safety of a vehicle are always the focus of great attention, while the wheels are used as important parts for directly contacting the road surface and bearing the key functions of running, braking and the like, the stability of the working state of the vehicle has a critical influence on the whole vehicle performance, under long-time running, the friction between the wheels and the ground can cause the temperature of the wheels to rise rapidly, if heat dissipation is not timely, the gas in the tires expands due to heating, the tire pressure is possibly too high, the tire burst risk is increased, and the running safety is seriously endangered. The traditional wheel heat dissipation mode mainly relies on simple natural convection heat dissipation, heat is slowly dissipated into surrounding air through the metal material of the wheel, but the heat dissipation efficiency of the mode is extremely low, the natural convection heat dissipation can not meet the heat dissipation requirement of the wheel far away in the face of the modern high-speed and heavy-load traffic demand, and the untimely heat dissipation can lead to the performance reduction of the wheel to influence driving.
