Network equipment cabinet

Abstract

The invention provides a network equipment cabinet, which is provided with a network equipment working chamber (2) and a circulation chamber (3) divided by a horizontal partition board (1), wherein the network equipment working chamber (2) and the circulation chamber (3) are communicated to form an annularly-sealed air duct through a first channel (4) and a second channel (5); a fan (6) is contained in the circulation chamber (3); the first channel (4) is communicated with a refrigerating fluid assigning device (11) arranged outside the cabinet; an outlet (13) is arrange at one side of the network equipment working chamber (2), which is near the second channel (5); the outlet (13) is communicated with a refrigerating fluid recovering and separating device (14) arranged outside the cabinet; the refrigerating fluid recovering and separating device (14) is connected with the refrigerating fluid assigning device (11); the refrigerating fluid assigning device (11) assigns refrigerating fluid to the first channel (4); and an assigning amount of the refrigerating fluid can be controlled to be less than a recovery amount. The refrigerating fluid is in direct contact with network equipment, so that the cooling density is large; the network equipment can be effectively cooled; and the network equipment cabinet has no need of a completed heat radiation pipeline, and has no need of greatly changing the network equipment and the cabinet in design.

Description

technical field [0001] The invention relates to the field of network equipment, in particular to a network equipment cabinet. Background technique [0002] Network equipment cabinets are typically densely packed with servers, switches, storage devices, and other equipment that consume power and generate heat. As the performance of network equipment improves, the power consumed by it is also increasing. As a result, a very concentrated heat load will be formed in the network equipment cabinet, and if the heat generated by these heat loads is not dissipated in time, it will affect the performance, Both safety and service life are extremely detrimental. [0003] At present, the cooling strategy of the network equipment cabinet is to use the near-end cooling mode, covering the surface of the heating device with the cold plate of the refrigerant or refrigerant, or even directly covering the surface of the chip, but it also brings some problems, such as the whole device A large ...

Problems solved by technology

With the improvement of network equipment performance, its power consumption is also increasing. As a result, a very concentrated heat load will be formed in the network equipment cabinet, and if the heat generated by these heat loads is not dissipated in time, it will affect the performance of network equipment, Both safety and service life are extremely detrimental

[0003] At present, the cooling strategy of the network equipment cabinet is to adopt the near-end cooling mode, covering the surface of the heating equipment with the cold plate of the brine or refrigerant, or even directly covering the surface of the chip, but at the same time it brings some problems, such as the whole equipment A large number of heat dissipation pipes are added inside, resulting in poorer heat dissipation inside the cabinet, which cannot solve the heat dissipation of equipment with greater heat density, and the volume of the entire server or heat-generating equipment will cause design changes due to its heat dissipation mechanism
