Our Technology
How radiative cooling metamaterials achieve zero-energy temperature reduction under direct sunlight.
Radiative Cooling Principle
Using 8–13μm Atmospheric Window
Our material radiates heat through the atmospheric window directly to outer space — no energy input required.
The Science Behind DeepSpaceCool
DeepSpaceCool's radiative cooling metamaterial works by creating an efficient heat transfer channel between the Earth's surface and outer space. It leverages the 8–13μm atmospheric window — a specific infrared band where the atmosphere is nearly transparent — to radiate heat directly into the cold void of space.
Unlike traditional "cooling" materials that merely block or reflect sunlight (which can still absorb and re-radiate heat), our material actively emits heat while simultaneously reflecting solar radiation, resulting in a net cooling effect even under direct sunlight.
High Solar Reflectivity
The material reflects 84-85% of incoming solar radiation (300nm–3μm), preventing heat absorption at the surface.
Strong Infrared Emission
With an emissivity of ≥0.9 in the 8–13μm atmospheric window, the material efficiently radiates heat to outer space.
Zero-Energy Cooling
The entire process is passive — no electricity, no moving parts, no chemicals. Just continuous, silent cooling.
Flexible Integration
The metamaterial can be applied to fabrics, films, and coatings, making it adaptable across products from clothing to automotive covers.
Material Performance Profile
Our cooling fabric outperforms across all key metrics — verified by independent lab testing.
Cooling Power Comparison
DeepSpaceCool's radiative cooling power rivals conventional active cooling — without consuming a single watt of electricity.
How Radiative Cooling Works
Four layers of innovation working together to achieve zero-energy cooling under direct sunlight.
Reflect Solar Radiation
85% of incoming sunlight is reflected away from the surface. Standard materials absorb this energy and heat up.
Emit Through Window
Heat is converted to 8-13μm infrared radiation that passes through the atmospheric window — a gap where air is transparent to IR.
Radiate to Outer Space
The IR radiation travels through the atmosphere into cold outer space (-270°C). This creates a continuous heat extraction loop.
