CooliBlade
Developing Distinctive Thermal Management Solutions

Thermal management is a crucial aspect of power electronics products. More than 50 percent of all failures in electronics are due to high temperatures or overheating. This can become a more critical concern in the coming years, given the continuous rise in power levels and power densities. The situation underscores the need for better thermal management systems.

CooliBlade addresses this requirement by bringing cutting-edge thermal management solutions for the most demanding high-power electronics applications.

"We have developed a distinctive thermal management solution called NEOcore technology. It is the first full aluminum heat sink structure based on phase change technology, providing extreme performance and cost-efficiency. The structure removes all additional thermal interfaces typically used in other solutions," says Janne Suhonen, CEO of CooliBlade.

NEOcore can ensure up to a 50 percent performance increase compared to the traditional thermal management systems available. The technology is based on an integrated 3-in-1 thermal channel that provides an instant thermal flow from the heat source through the thermal channel and fins. Further, CooliBlade customizes the optimal cooling solution for the clients' products.

The functionality of the thermal channel consists of three parts:

Evaporator - The working fluid vaporizes in the evaporator, and it transfers the heat to the entire structure until it returns to the evaporator as a liquid.

Thermal channel - The heated vapor moves instantly up in the thermal channel. The whole thermal channel structure is used for heat dissipation. NEOcore thermal channels are wickless.

Condenser - The optimized condenser functions as an optimal air interface.

CooliBlade has various product platforms developed for different power electronics applications. Its products can meet the most demanding specifications set by leading-edge customers in the AC drives, IGBTs, telecommunication, renewable energy, and EV charging fields. The company has developed these platforms to fulfill customer expectations and is committed to delivering the best quality products that combine performance and cost-efficiency expectations.

For example, CooliBlade worked with one of the biggest power inverter companies to create a new product platform and get maximum power output from their product. The system's size was critical for the client, and they didn't like to use liquid cooling in their applications. They were looking for the most efficient air-cooling solution. With the help of CooliBlade, they were able to reach higher performance and increase reliability. CooliBlade reduced the weight of their existing cooling system by 50 percent, and the client now operates in higher ambient temperatures.

CooliBlade is continuously developing its technology platforms forward. The company now has direct cooling technology platforms under development. One of its goals is to remove the need for thermal interface material (TIM) from future power electronics systems or modules. This will bring performance to the next level and increase the reliability of high-power products.

The company is committed to advancing electrification and promoting sustainable green transitions through its innovative thermal management solutions. The company's products are 100 percent recyclable and enhance the longevity of its customers' products. By reducing electronic waste, it aligns with its strong environmental values, and this commitment continues to inspire the company's ongoing product development efforts.
