technical field [0001] The invention relates to an electronic radiator combined with air and water cooling, belonging to the technical field of electronic radiators. Background technique [0002] Electronic radiators are usually heat sinks for heat dissipation of high-power electronic components, and are divided according to cooling methods. There are natural cooling radiators, air cooling radiators, liquid cooling radiators, etc., which are widely used in power devices, modules, resistors, inverters, graphics cards, motors, power supplies, IT and other electronic fields. The natural cooling radiator mainly uses the profile fins to increase the heat dissipation area and the natural heat transfer of the air to achieve the purpose of cooling, and the accumulation of hot air affects the heat dissipation efficiency; Turbine effect induced draft increases the change of cold air to improve heat dissipation efficiency, but the profile inserts of the support seat at the bottom of t...

Problems solved by technology

Naturally cooled radiators mainly use profile ribs to increase the heat dissipation area and air natural heat transfer to achieve the purpose of cooling, and the accumulation of hot air affects the heat dissipation efficiency; Turbine effect induces wind to increase cold air alternately to improve heat dissipation efficiency, but the profile inserts at the bottom of the fan support are usually in the form of rectangles or sunflowers, which are in complete contact with the heating electronic parts, and the circulation of the bottom air fluid is insufficient, resulting in replacement of cold air and contact with the profile Insufficient contact, the structure of the fan cover affects the installation and reduces the installation diameter of the fan, which affects the safety protection strength, resulting in poor energy efficiency

[0003] Liquid cooling is also a water-cooled radiator. A cold water pipe is installed in the heat sink profile to achieve the purpose of cooling through the heat transfer of cold water. However, the distribution of the cold water pipe in the heat sink profile is limited, resulting in slow heat transfer at the edge of the profile, making it difficult to achieve the expected effect of energy efficiency. ; At the same time, the radiator profile involved adopts an integrated structure, which is inconvenient to disassemble and install, and it is difficult to meet the needs of use
