Description

technical field [0001] The invention belongs to the technical field of heat dissipation of electronic equipment, and specifically relates to a modular air-cooled chassis structure for enhanced heat dissipation. Background technique [0002] Existing traditional modular electronic chassis (or "rack") has two types of horizontal heat dissipation and vertical heat dissipation. Both solutions can achieve a certain degree of heat dissipation while isolating the flowing air and the electronic module. [0003] The heat dissipation structure of the modular electronic chassis with horizontal heat dissipation is generally in series, and the main disadvantage lies in the heat superposition effect. Along the direction of air flow, the air cools each electronic module in turn, and the air temperature increases in turn. As a result, the cooling air temperature in the adjacent rail plate of the electronic modules installed at the rear of the air flow has increased considerably, usually b...

Problems solved by technology

[0004] Under the trend of further increasing the working heat of electronic modules, the above-mentioned two schemes of horizontal heat dissipation and vertical heat dissipation have relatively large limitations and are difficult to adapt to

At the same time, the contact surface between the electronic module and the rail plate heat sink is narrow, the heat dissipation path is long, and the temperature rise gradient is extremely large
