i2Cool Raises CNY 30 Million Series B

i2Cool (深圳市创冷科技有限公司), a Hong Kong and Shenzhen-based materials company, has raised a CNY 30 million Series B round led by Toukong Donghai Capital. The funding was announced on September 4, 2026.

What the Company Does

Founded in 2022, i2Cool develops electricity-free passive radiative cooling products. Its core technology is based on standardized nanoparticles that are formulated into coatings, films, powder coatings, and textiles. These materials reflect sunlight and radiate heat through the 8–13 micron atmospheric window, providing cooling without the need for electrical power.

The technology originated from research conducted at City University of Hong Kong and published in Science.

Commercial Traction

i2Cool's products have been deployed across more than 500 projects in over 30 countries. Its customer sectors span:

• Architecture
• Power and telecom
• Photovoltaics
• Logistics
• Grain storage

The company is now extending its particle-plus-materials platform into high-growth scenarios, including AI data centers and new energy vehicles.

The Round

• Round type: Series B
• Amount: CNY 30 million
• Announced: September 4, 2026
• Lead investor: Toukong Donghai Capital

Why It Matters

i2Cool sits at the intersection of advanced materials and energy efficiency. Its passive radiative cooling approach addresses cooling demand without adding electrical load — a proposition with clear relevance to data centers, where thermal management is a major cost and power constraint, and to electric vehicles, where thermal control affects range and battery performance.

With an established deployment footprint across 30-plus countries and a research pedigree tied to published Science work, the company has moved beyond the lab stage into commercial scale. The Series B capital is positioned to support its expansion into these newer verticals.

Acquisition Angle

For strategic buyers in materials, HVAC, data center infrastructure, or building products, i2Cool represents a platform with:

• A standardized nanoparticle manufacturing approach rather than one-off custom formulations
• Multiple product formats (coatings, films, powder coatings, textiles) addressable across distinct end markets
• Existing international deployment across 500+ projects
• A technology base with academic validation

The extension into AI data centers and new energy vehicles signals a deliberate move toward higher-margin, higher-growth applications where thermal management is a critical bottleneck.

Summary

i2Cool has closed a CNY 30 million Series B led by Toukong Donghai Capital. The Hong Kong and Shenzhen materials company, founded in 2022, builds electricity-free passive radiative cooling products from standardized nanoparticles and has deployed them across 500+ projects in more than 30 countries. It is now pushing its platform into AI data centers and new energy vehicles.
