Major Track Record

Evaluating the final performance of complete vehicles
Climatic Wind Tunnel (Climatic Wind Tunnel)

A test facility that installs a complete vehicle (automobiles, railway vehicles, construction equipment, etc.) in a test chamber and reproduces the most extreme climatic conditions
to develop vehicle performance under the same conditions as the actual site.

Climatic Wind Tunnel test chamber view

An automotive climatic wind tunnel combines an air circulation system, refrigeration/heating system, humidification/dehumidification system, solar system, rain/snow system, vehicle power system, exhaust gas discharge system, ventilation system, and control and data acquisition & processing system to realize temperature, humidity, solar radiation, wind speed, road simulation, and more within the vehicle.

Climatic Wind Tunnel System Components

Wind Speed Reproduction System

Equipment that reproduces wind speed at the same speed as the vehicle driving speed

Temperature Control System

A device that raises and lowers temperature to test vehicle performance

Humidity Control System

A device that tests vehicle performance through humidification and dehumidification

Solar Reproduction Facility

A device that reproduces real sunlight to test vehicle performance

Vehicle Power Reproduction Facility

A device that simulates actual road driving to collect data needed for operation

Snow & Rain System

A device that simulates snow and rain to test vehicle performance

Integrated Control System

A program that configures the equipment for integrated operation

As the reliability of automotive components under diverse environmental conditions is essential, the climatic wind tunnel serves as a facility to enhance the reliability of each component and improve the overall performance of the complete vehicle, and its construction at automobile manufacturers continues to increase.

The Whale Corp. completed the GM Daewoo Korea Climatic Wind Tunnel on a turnkey basis, and the Shanghai GM Climatic Wind Tunnel, as the first project for a Chinese automaker, verified its original core technology.

The Whale Corp. also devotes its full efforts to climatic wind tunnel R&D, accelerating the development of various new technologies and materials, and pursuing the standardization and convenience of productive and eco-friendly facility operation to supply customers with the highest-quality climatic wind tunnels.
