FAR-EDGE SERVER WITH SINGLE-PHASE IMMERSION COOLING
Described herein is a wireless-telecom server for implementation proximate a remote radio-unit (RRU) (e.g., on a same pole as the RRU). The server includes an internal enclosure with wireless-telecom network cards and a dielectric liquid disposed therein. The server also includes pumps configured to circulate the dielectric liquid within the internal enclosure. The server further includes a network connection configured to communicate with a network, radio connection configured to communicate with the RRU, and a power connection configured to supply power to the server. The network connection, the radio connection, and the power connection pass through a wall of the internal enclosure. The server also includes fans configured to direct air around the internal enclosure. By configuring the server for placement proximate the RRU, a need for a server room near the RRU and/or a high number of long fiber-optic cable runs may be obviated.

network equipment-building system (NEBS) class 4 protection.
3 . The far-edge server of claim 1 , wherein the fans are proximate a first side of the wireless-telecom server and the network connection, the radio connection, and the power connection are on a second side of the wireless-telecom server.
4 . The far-edge server of claim 1 , further including exterior fins on an exterior of the internal enclosure.
5 . The far-edge server of claim 4 , further including interior fins on an interior of the internal enclosure.
6 . The far-edge server of claim 4 , wherein:
the wireless-telecom server further includes an external enclosure surrounding the exterior fins; and
the fans are configured to force air between the internal enclosure and the external enclosure.
7 . The far-edge server of claim 6 , wherein the external enclosure is open on an end opposite the fans.
8 . The far-edge server of claim 1 , wherein the network connection and the radio connection include network ports disposed through a wall of the internal enclosure.
9 . The far-edge server of claim 8 , wherein the network ports are disposed on the wireless-telecom network cards.
10 . The far-edge server of claim 1 , wherein the wireless-telecom network cards include a plurality of network cards that are stacked on one another.
11 . The far-edge server of claim 1 , wherein the wireless-telecom server further includes a processing unit.
12 . The far-edge server of claim 11 , wherein:
the pumps are disposed within the internal enclosure; and
the processing unit is disposed between the pumps and the wireless-telecom network cards.
13 . The far-edge server of claim 11 , wherein the wireless-telecom server further includes a fluid cap configured to direct one of influent flows or effluent flows from the pumps towards one or more walls of the internal enclosure and another of the influent flows or the effluent flows across the processing unit.
14 . The far-edge server of claim 1 , wherein the wireless-telecom server further includes a heater configured to maintain the dielectric liquid above a pre-set temperature.
15 . The far-edge server of claim 1 , wherein the pumps are disposed within the internal enclosure.
16 . The far-edge server of claim 1 , wherein the internal enclosure further includes a pressure relieving device configured to mitigate a pressure differential between an interior of the internal enclosure and an exterior of the internal enclosure.
17 . The far-edge server of claim 1 , wherein the radio connection includes one or more fiber-optic connections.
18 . The far-edge server of claim 1 , wherein:
the wireless-telecom server includes an internal temperature probe; and
the wireless-telecom server is configured to control the pumps and the fans based on information received from the internal temperature probe.
