Increasing Demand for Efficient Cooling in Power Electronic Equipment

图片
With the continuous advancement of modern mechanical and electronic technology, power electronic equipment is being used more extensively in critical areas such as national defense, military industry, and communications. These systems are evolving to become more compact, complex, and thermally dense, thereby increasing the demands on their cooling performance. In large-capacity power electronic equipment, the heat generated by power devices is substantial, and traditional air-cooled radiators are often insufficient. Liquid cold plate , with their high efficiency, allow for a closer arrangement of devices, resulting in higher integration and a more compact structure. This efficient cooling method effectively addresses the heat dissipation challenges of large-capacity electronic devices.

Design of Water Cooling Plates

图片
Water cooling   plate , also known as liquid co ld plate , operates on a straightforward principle: within a closed liquid circulation system, a pump circulates the liquid, which absorbs heat from a heat sink attached to the power source. This heated liquid then travels to a larger cooling device where it dissipates the heat. The cooled liquid returns to the heat-absorbing equipment, and the cycle repeats continuously. Water cooling   plate   is highly efficient, boasting thermal conductivity over 20 times greater than traditional air cooling methods. This efficiency enables it to handle heat dissipation needs ranging from hundreds to several kilowatts. Consequently, water cooling plates   are widely used in various industries, including laser technology, military applications, medical equipment, power electronics, and industrial machinery.

What Is the Function of Water Cooling Plate

图片
The water-cooled plate   is a device used for heat dissipation, which mainly plays the role of cooling and maintaining the normal working temperature of the equipment. Its role is mainly reflected in the following aspects: First of all, the water-cooled plate can efficiently dissipate the heat generated by the equipment. In some high-performance electronic equipment, computer hardware or industrial production equipment, due to high load operation, a lot of heat will be generated. The water cooling plate conducts heat through the water flow, takes away the heat energy of the surface of the equipment, effectively reduces the temperature of the equipment, and ensures that the equipment operates within the appropriate temperature range. Secondly, the water cooling plate helps to improve the working efficiency of the equipment. Excessive temperature may degrade device performance or even cause faults. The application of water-cooled plate can prevent the equipment from overheating, keep the

Cold Forged Heat Sink

Cold forging   is a process for shaping and forming profiles below their recrystallization temperature, typically at room temperature. This method is primarily used with materials that have low deformation resistance and good plasticity at room temperature, such as aluminum, copper, and their respective alloys. Cold forging can induce work hardening (strain hardening) in the material, increasing its strength and hardness. Heat sink   manufacturers widely utilize the cold forging process for producing light source heat sinks and LED heat sinks .   Lori Thermal   was among the pioneers in manufacturing cold forged radiators and has amassed extensive experience in this technique. Beyond producing standard light source heat sinks , Lori Thermal has developed advanced technology for manufacturing high-power cold forged heat sinks .

Heat Pipe Heat Sink

Heat pipes   are heat transfer elements with exceptionally high thermal conductivity. They reached the peak of theoretical research in the late 1960s and began to see widespread industrial use in the 1970s. These devices transfer heat by changing the steam and liquid phases of the working medium within a completely sealed vacuum tube, achieving thermal conductivity hundreds of times greater than that of pure copper. Due to this property, heat pipes are often referred to as "thermal superconductors."   A heat pipe heat sink   is an innovative product that can significantly enhance the performance of traditional heat sinks or heat exchange systems by utilizing heat pipe technology. Since the introduction of heat pipes, the cooling systems for power electronic devices have undergone substantial advancements.

Friction Welding Liquid Cold Plate

图片
Friction welding   is a solid-state welding technique that joins materials without reaching their melting points. This method uses pressure, combined with constant or increasing torque, to generate frictional and plastic deformation heat at the contact surfaces. The heat produced raises the temperature in the contact area to a range near but typically below the melting point of the materials. As the temperature increases, the material’s deformation resistance decreases, its plasticity increases, and the oxide film at the interface breaks down. Under the applied pressure, molecular diffusion and recrystallization occur at the interface, resulting in a solid-state weld through the material's plastic deformation and flow. Unlike traditional fusion welding, friction welding does not melt the materials being joined. Instead, it creates a thermoplastic state where solid-phase bonding occurs. This process results in welded joints that can match the strength of the base materials, offering
