Optimizing Tire Performance with Efficient Cooling Systems

Tire temperature control system for vehicles that provides efficient and automated tire heating and cooling to improve tire performance and safety in various conditions. The system uses both liquid and gas circulation paths to heat or cool the tires through dedicated modules. The tire temperature is monitored along with ambient temperature to determine when to activate heating or cooling. This allows proactive temperature control based on environment and tire conditions. The liquid path uses a heat exchanger to circulate fluid between the tires and a liquid treatment module. The gas path has a compressor to circulate gas between the tires and a gas treatment module. This dual-path system provides more flexibility and efficiency compared to relying solely on external heating or airflow cooling.

A spray-type automobile tire temperature regulation system to prevent tire overheating in summer and tire slippage in winter. The system has components for cooling and heating the tires. When tire temperature is too high, a pump pumps hot water from a storage tank to a spray head on the tire. When tire temperature is too low, a pump pumps cold condensed water from a storage tank to a spray head on the tire. A water tank stores water for both pumps, and a level gauge monitors water level.

Vehicle tire temperature regulation system that intelligently cools tires based on road conditions and tire temperature to improve safety and traction. The system uses sensors to detect tire temperature and road conditions like slope and surface conditions. It then adjusts water spray cooling accordingly. For example, less cooling on dry smooth roads versus more cooling on wet slippery roads. The system also monitors water temperature and level to optimize cooling effectiveness. This prevents overcooling on dry roads that can cause skidding.

Tire cooling system to maintain stable tire pressure during temperature-sensitive tire pressure monitoring tests. The system uses a pump to circulate low-temperature air from the car's AC evaporator through the tire. It achieves dynamic pressure balance by matching inflator speed and valve outlet area to equalize inflation and deflation. This replaces hot air inside the tire with cooler air to prevent excessive pressure increases caused by high internal temperatures.

Device to cool automobile tires without splashing water that allows controlled cooling without rapid temperature swings. The device has a U-shaped tube with a heat conductor contacting one end of the wheel. When driving normally, the heat conductor is close to the wheel but not touching the end surface. This allows heat transfer fluid to flow through the tube. When cooling is needed, the heat conductor contacts the end surface to increase fluid flow and cool the wheel faster.

Self-adaptive cooling system for truck tires that automatically regulates tire temperature during driving to prevent overheating. The system uses a mechanism with sliding balls, springs, gears, and a flow control device that adjusts airflow through the tires based on speed and temperature. The mechanism is mounted on the wheel hub and connected to the brake caliper. It has a detection chamber with balls, springs, and gears that sense tire temperature and a transmission chamber with rods and gears that control airflow. A flow disc with an eccentric hole drives a gear to regulate airflow through the shunt cavities in the wheel hubs. This allows air to be directed to the tires as needed to cool them during high-speed or heavy-load driving.

A hybrid water-cooled and air-cooled tire cooling system for trucks that leverages solar power to improve cooling efficiency. The system uses solar panels on the roof to generate electricity, a battery to store it, and a tire cooling controller to manage the water pump, fan, and mist nozzles. This allows converting the water-cooled system into a combined water-cooled and air-cooled system by misting the tires with high-pressure water. The mist evaporates to cool the tires, aided by the fan. This improves cooling compared to just water spraying. The solar panels power the system without needing an external power source.

A vehicle tire cooling system that automatically releases water from the tire to absorb heat and protect against damage from high road temperatures. The system has a water storage chamber around the tire that rotates with the tire. A valve in the chamber allows water to be discharged through the tire tread grooves. The valve closes when the car stops and opens as speed increases, automatically adjusting water flow based on vehicle velocity. The discharged water absorbs heat between the tire and road, reducing damage. When the tire is stationary, the valve is closed to prevent leakage.

Cooling system for pneumatic tires to prevent internal heat buildup and tire failure at high speeds and loads. The system involves attaching a heat exchanger to the inside surface of the tire. Coolant flows through the exchanger inlets and outlets. The exchanger absorbs heat from the tire interior as the tire flexes and transfers it to the coolant. This coolant can then be circulated externally to a pump attached to the wheel rim. The pump rotates with the wheel and provides continuous cooling. The coolant can be circulated internally or externally, depending on the configuration.

Pneumatic tire with an internal cooling system to reduce internal temperatures and prevent delamination. The tire has a coolant circulation unit inside the tread and/or shoulder that circulates a cooling fluid. The circulation unit is bent and may have a protruding heat dissipation part. This closed loop cooling system prevents peeling by lowering internal temperatures when the tire is hot. It prevents cracking by keeping the coolant completely enclosed.

An automobile tire cooling device to prevent tires from overheating during driving, especially in hot weather. The device mounts inside the wheel well and uses a blowing impeller to directly cool the tires. It also has spray nozzles with liquid nitrogen to further cool the tires. A temperature sensor triggers the nitrogen spray when needed. The impeller and driving impeller are coaxially connected, with the driving impeller outside the wheel well. This allows the blowing impeller to directly face the tires. The device connects to a liquid nitrogen tank and ECU for control.

Tire cooling system for cars that reduces tire temperatures without adding weight or water tanks. The system uses the car's refrigeration system to cool tires. A compressor, condenser, throttle, and heat exchanger connected to the refrigerant lines are added. The heat exchanger is mounted on the axle. When the compressor runs, it chills the refrigerant. The throttle reduces pressure. The cooled refrigerant flows through the axle heat exchanger to absorb heat. Spokes connect the axle and wheels, allowing heat transfer. The cooled axle then transfers heat to the tires. This smart system intelligently cools tires using the car's AC instead of adding weight and water.

Preventing overheating of tires in vehicles by diverting air conditioning cooling to the brake system to prevent heat transfer that damages the tires. The system has a dedicated cooling path from the vehicle's air conditioner to the brakes, bypassing the passenger cabin. It connects the air conditioner's horizontal duct to a separate cold air supply near the brakes. This prevents tire heating caused by brake system heat transfer. The system uses the air conditioner's cold air to cool the brakes instead of letting it flow into the cabin.

A vehicle hub cooling system for trucks that uses a water-circulating system to cool the hubs and brakes of heavy duty vehicles like trucks. The system consists of a water tank, pipes, and a water-filled hub assembly. Water is pumped into the hub through a pipe connected to the tank. The hub components like the wheel core, axle, and adjusting mechanism have internal water channels. The water circulates through these components to cool them. The water exits the hub through another pipe and returns to the tank. This closed loop water cooling system prevents overheating of the hubs and brakes in high-temperature applications like mountainous areas. It eliminates the need for manual watering of hubs during drives.

Cooling method for tires on vehicles with pneumatic tires that reduces heat generation and improves durability during low-pressure runs like blowouts or running flat. The method involves actively cooling the tires when pressure drops below a threshold. This can be done by blowing fluid onto the inside of the tire or onto the tire equator from outside. The fluid cools the tire and prevents excessive heat buildup that can degrade the rubber. The cooling is triggered when tire pressure falls below a certain level during running.
