Description

technical field

[0001] The invention belongs to the three technical fields of machinery, heat and electromagnetics, and relates to a multi-channel composite sealed case used in an electronic case, and an electronic device with good airtightness and electromagnetic shielding function. Background technique

[0002] Chassis are widely used in electronic equipment. Traditional chassis mainly rely on conduction heat dissipation: internal modules conduct heat to the chassis shell through structures such as locking strips or thermal pads, and the outside of the chassis takes heat away through natural convection or forced convection, and the chassis acts as a heat exchanger. The problem is that the contact thermal resistance is large and the heat conduction efficiency is not high. At present, electronic equipment is developing towards high density, high power, and miniaturization. The unit heat flux value in electronic equipment is increasing, and the temperature is getting higher ...
