![]() The main disadvantage of active thermal management is that it requires the use of electricity and therefore results in higher costs, compared to passive cooling.ĭownload this free case study to learn how thermal simulation with the SimScale cloud-based platform helped QRC Technologies to implement advanced cooling techniques and optimize heat dissipation for its RF testing equipment. They are commonly integrated into electronics, such as computer cases, or are attached to CPUs, hard drives or chipsets to maintain thermal conditions and reduce failure risk. Fans are used when natural convection is insufficient to remove heat. Through active cooling technologies, the rate of fluid flow increases during convection, which dramatically increases the rate of heat removal.Īctive cooling solutions include forced air through a fan or blower, forced liquid, and thermoelectric coolers (TECs), which can be used to optimize thermal management on all levels. Passive Cooling Active CoolingĪctive cooling, on the other hand, refers to cooling technologies that rely on an external device to enhance heat transfer. To sum it up-passive thermal management is a cost-effective and energy-efficient solution that relies on heat sinks, heat spreaders, heat pipes or thermal interface materials (TIM) to maintain optimal operating temperatures.ĭownload ‘Electronics Cooling: The Ultimate Guide’ to learn everything you need to know about modern electronics cooling.Īctive vs. A growing trend in this regards can be witnessed in what is commonly known in the industry as passive houses. This leads to proper cooling of electronic products and thermal comfort in homes or office buildings by keeping them under the maximum allowed operating temperature. In architectural design, natural resources like wind or soil are used as heat sinks to absorb or dissipate heat. Passive cooling achieves high levels of natural convection and heat dissipation by utilizing a heat spreader or a heat sink to maximize the radiation and convection heat transfer modes. The advantages of passive cooling techniques lie in the energy efficiency and lower financial cost, making it an astute systems design choice for the thermal management of both buildings and electronic products. But what is the difference between them? Active vs. These systems can be divided into two main categories: those with active and with passive cooling techniques. To tackle and alleviate the difficulties and inefficiencies that arise as a result of heat, engineers employ different cooling systems to manage conditions. Whether it’s a private home, an office building, or a dedicated server room, architectural considerations can have a huge impact on the thermal management solutions available.
