A water-cooled radiator is a device that uses liquid (usually water or other cooling liquids) to dissipate heat. It uses liquid to circulate under the drive of a pump to take away the heat from the radiator. Compared with air-cooled radiators, water-cooled radiators have the advantages of being quiet, stable in cooling, and less dependent on the environment. The core part of a water-cooled radiator is the water cooling system, which mainly includes components such as a water cooling head, a radiator, water pipes, a water pump, and a water tank. The water cooling head is fixed on the CPU or other components that need to be cooled, and is connected to the water pump and the radiator through water pipes to form a closed circulation system. When the CPU and other components are working, the heat generated is absorbed by the water cooling head, and then transmitted to the radiator through the water pipe, and the heat is dissipated into the air through the cooling fan. Water-cooled radiators can be divided into two categories: active water cooling and passive water cooling. Active water cooling requires the installation of a cooling fan to assist in heat dissipation, while passive water cooling relies solely on the water cooling radiator itself for heat dissipation. In addition, water-cooled radiators can also be divided into two types according to the installation method: built-in water cooling and external water cooling.The built-in water-cooling radiator needs to occupy the internal space of the chassis, while the working components such as the cooling water tank and water pump of the external water-cooling radiator are all arranged outside the chassis, which can reduce the space occupied in the chassis. Excellent water-cooling radiator brands include Kyushu Fengshen, Cooler Master, Asus, and Corsair. When choosing a water-cooling radiator, you need to choose the appropriate model and brand according to your own usage needs and budget. The installation and maintenance of the water-cooling radiator is also relatively complicated and requires certain professional knowledge and experience. During installation, you need to remove the motherboard and radiator first, then install the water cooling head on the parts that need heat dissipation, and connect the water pipes and water pumps and other components. During maintenance, the water-cooling radiator needs to be cleaned regularly and preservatives added to extend its service life. In short, the water-cooling radiator is an efficient and stable heat dissipation device suitable for computer systems that require high-performance heat dissipation. Working principle of water-cooling radiator The working principle of water-cooling radiator is mainly based on the principles of heat conduction and liquid circulation.Here is a detailed explanation of its basic working principle: Heat conduction: The water-cooled radiator is in direct contact with the heat-generating components such as the CPU and graphics card through its water-cooling head, and uses the good thermal conductivity of metals (such as copper or aluminum) to quickly conduct the heat generated by the heat-generating components to the liquid inside the water-cooling head. Liquid circulation: Once the heat is conducted to the water-cooling liquid (usually water or special heat-dissipating liquid), the liquid will be driven by a water pump and flow to the radiator (usually called a radiator) through pipes such as water pipes or hoses. Heat dissipation process: In the radiator, the heat in the liquid will be quickly dissipated into the surrounding air by the large-area heat sink. In order to speed up this process, a fan is usually equipped to blow air to enhance the heat dissipation effect. Liquid reflux: The dissipated liquid flows back to the water-cooling head through the water pipe and contacts the heat-generating components again for the next round of heat dissipation cycle. This cycle will continue to ensure that the heat-generating components such as the CPU and graphics card always run at a lower temperature. Compared with traditional air-cooling, water-cooled radiators usually provide more stable and efficient heat dissipation effects because the heat capacity of water is much greater than that of air, and it can absorb and dissipate heat more effectively.
