Performance Optimization of Multi-Sided Liquid Coolers by COOLTEC
A Multipress cooler can be thermally optimized in a targeted way – through the combination of tube materials, internal structures, and additional technologies. The result: maximum heat dissipation, uniform temperature distribution, and extended component lifetime.
Fluid-Conducting Inserts
Copper or stainless-steel inserts transfer heat directly to the circulating coolant. These can easily be combined with press-fitted tube systems to further increase overall performance – ideal for applications with high power density or dynamic temperature profiles.
Copper Inserts as Heat Spreaders
Embedded copper inserts evenly distribute generated heat across all cooling surfaces. This reduces hot spots, stabilizes operating temperature, and extends the lifetime of sensitive electronics.
Integrated Heat Pipes
Built-in heat pipes use phase-change technology to rapidly transfer heat from hot zones to cooler regions. This ensures consistent temperatures, especially in high-frequency or high-power applications.
