Hydraulic system: Stabilize the temperature of the hydraulic oil to prevent performance decline due to overheating. Compressor/bearing cooling, reduce industrial equipment produced by friction heat during operation. 2. Electronics and power electronics equipment heat dissipation, such as CPU, GPU, the heat pipe radiator (a kind of high efficient radiator pipe), through the phase change principle of fast heat conduction. Transformer/converter cooling: power equipment by oil cooling or water cooling pipe in the heat. LED lamps and lanterns: extend the life of the lamps and lanterns, avoid high temperature lead to droop. 3. Air conditioning (HVAC) - heating system, hot water or steam flow in the pipeline, through the radiator to heat to the indoor (e.g., household radiator). In the condenser/evaporator, air conditioning by copper or aluminum tube heat exchange. 4. New energy and the battery thermal management of high technology, the electric car battery balanced temperature through surface tube. The solar system: area.the absorb solar energy and heat transfer. 5. Other applications - medical equipment, such as magnetic resonance imaging (MRI), X-ray machine cooling system. Food processing, fermentation tank, the temperature of the drying equipment control. The characteristics of the radiator pipe material: copper, aluminum, good (thermal conductivity), commonly used stainless steel (corrosion) or composite materials. Structure: may be a fin (increasing heat dissipation area) or design for the micro channel (efficiency). Cooling: air cooling, surface, phase change cooling (e.g., heat pipe). According to the specific requirements, the design of the radiator tube (such as the diameter, material, layout) will be targeted optimization, in order to ensure efficient heat transfer.
