This article clarifies the fundamental differences between liquid cold plates and heat sinks. It explains that heat sinks passively transfer heat to ambient air via convection, suitable for moderate heat loads. In contrast, liquid cold plates actively transfer heat to a circulating liquid, offering superior heat dissipation, better temperature uniformity, and precise control for high heat flux applications. The article details their distinct designs, performance capabilities, typical applications (e.g., heat sinks in consumer electronics, cold plates in EVs/data centers), and cost/complexity implications. Kingka's ability to provide both customized solutions is also highlighted. Read More

This article explains why EV manufacturers are increasingly adopting liquid cold plate cooling over traditional air cooling. It highlights that liquid cold plates offer superior thermal management, which is crucial for enhancing battery performance (higher power, consistent delivery), extending battery life (preventing degradation from temperature extremes), improving charging speed (dissipating heat from fast charging), and boosting safety (preventing thermal runaway and aiding fire containment). The article details the limitations of air cooling and how liquid cold plates overcome these, making them essential for modern EVs. Kingka's role in providing customized, high-quality liquid cold plate solutions for the automotive industry is also emphasized. Read More

This article addresses the common causes of poor performance in liquid cold plates and provides actionable solutions. It identifies four primary culprits: inadequate coolant flow (due to weak pumps, clogs, or high pressure drop), high thermal resistance (from poor surface contact or improper TIM), degraded coolant quality (contamination, degradation, or air bubbles), and improper installation (uneven mounting or damage). For each cause, the article details specific issues and offers practical fixes, such as optimizing pump settings, cleaning channels, improving surface flatness, maintaining coolant quality, and ensuring correct installation. Kingka's role as a one-stop thermal solution provider is highlighted, emphasizing their expertise in design, manufacturing, and quality control to prevent and resolve performance issues, ensuring reliable thermal management.
