Air-cooling and water-cooling combined electronic radiator

Abstract

The invention relates to an air-cooling and water-cooling combined electronic radiator. The electronic radiator comprises a fan and a fan cover located outside the fan, the bottom of the fan cover isprovided with a first radiator with the section being an isosceles trapezoid structure and a second radiator and a third radiator which are located at the two sides of the first radiator and of whichthe sections are right-angled trapezoid structures. A plurality of first notches and second notches are formed at the two sides of the first radiator, and insertion strips matched in an inserted manner are arranged between the two sides of the first radiator and the second radiator and between the two sides of the first radiator and the third radiator respectively. A plurality of third notches andfourth notches are respectively formed at the tops of the second radiator and the third radiator, and at least one through cold water pipe is arranged on each of the first radiator, the second radiator and the third radiator, so that the reliable strength of an installation structure is guaranteed. The second radiator and the third radiator which are detachably connected form a supporting combination for the first radiator to achieve contact type heat transfer, the air cooling and the water cooling are used at the same time to increase the air flux, so that the air circulation performance isimproved, the heat dissipation energy efficiency is remarkably improved, and the heat dissipation requirement of an electronic device is met.

technical field [0001] The invention relates to an electronic radiator combined with air cooling and water cooling, and belongs to the technical field of electronic radiators. Background technique [0002] Electronic heat sinks are usually heat sinks for high-power electronic components, which 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. 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 rect...

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
