Description

Orthogonal frame plug box liquid cooling heat abstractor

Technical Field

The utility model relates to an electronic equipment liquid cooling heat abstractor especially relates to an orthogonal framework subrack liquid cooling heat abstractor.

Background

With the continuous development of electronic technology, the power of an electronic equipment system is larger and larger, but the physical size is smaller and smaller, the heat flux density is also increased sharply, and the heat dissipation risk is increased. Especially in certain kind of subrack equipment, the consumption is bigger and bigger, and traditional forced air cooling heat dissipation challenge is more and more, and the heat dissipation difficult problem is outstanding. Therefore, the problem that the equipment dissipates heat becomes an industrial difficulty and a pain point is solved.

For the plug-in box equipment, a straight ventilation mode is adopted in a conventional framework, cold air enters a base air channel from an air inlet of a front panel, flows into an exchange plate through a keel with positioning and supporting functions after passing through a wire clamp heating device, and brings heat of the exchange plate and a wire clamp into a fan positioned in a rear row and discharges the fan into the environment. The heat dissipation scheme of the heating devices on the line cards and the exchange plates of the heat exchange device is generally to adopt an air-cooled fin radiator for heat dissipation.

As shown in fig. 1 (top view) and fig. 2 (three-dimensional schematic view), which are schematic views of a conventional orthogonal air-cooling heat dissipation structure plug box, the orthogonal air-cooling heat dissipation structure plug box includes a plug box frame 2, a line card 1, an exchange board 3, a keel 7, a back board 6, a heat generating device 5, a heat sink 4, and a fan 8. Wherein the fan is located the back row, and the wind channel is the straight ventilation form that goes out after advancing, and the system is the convulsions form, and cold wind gets into the ply-yarn drill through the hole on the ply-yarn drill panel, takes away the device heat that generates heat on the ply-yarn drill 1 and gets into the exchange board from fossil fragments trompil position, takes away the device heat that generates heat on the exchange board 3 again and passes through fan discharge system. Specifically, cold air enters the wire clamp 1 from the hole of the front panel, and the heating device 5 transfers heat to the air-cooled fin radiator 4, so that the heat is transferred to the air environment around the wire clamp through the radiator 4. The hot air flows through the heat source and obtains heat, and the hot air continues to move downstream, enters the exchange plate through the back plate 6 and the keel 7 (the back plate and the keel are structural members required for realizing functions), further takes away the heat of the heat source on the exchange plate, enters the exhaust fan 8 of the system, and is discharged into the surrounding environment. The straight ventilation duct type is one of the air cooling heat dissipation types with the highest heat dissipation efficiency at present.

The contact surface between the heating device 5 and the air-cooled heat sink 4 is usually filled with interface material to reduce the interface thermal resistance. Along with the increasing power of heating devices, the conventional air-cooled heat dissipation scheme cannot meet the requirement of thermal reliability of the devices due to the limitation of the size and the heat dissipation capacity of the air-cooled heat dissipation device, and further the devices are overheated, equipment downtime occurs and other faults occur. In summary, when such heat dissipation problems are encountered, the heat dissipation of the equipment cannot be solved by the conventional air cooling scheme.

Therefore, a new heat dissipation scheme and apparatus is needed to meet the heat dissipation requirement of the orthogonal-structure plug box 2. Thereby ensuring the stable, safe and reliable operation of the electronic equipment.
