    摘要： Embodiments are disclosed of an information technology (IT) cooling system. The system includes an IT container having an internal volume. Inside the internal volume there is an immersion fluid region adapted to submerge one or more servers in a two-phase immersion fluid. An immersion condenser is positioned above the immersion fluid region in the internal volume. The design includes a circulation condenser. The circulation condenser is fluidly coupled to a liquid distribution manifold and a vapor return manifold that are positioned in the internal volume above the immersion tank (i.e., the immersion fluid region) and are adapted to circulate a two-phase circulation fluid. The circulation condenser is also fluidly coupled to the immersion condenser, and an external cooling fluid is pumped from the circulation condenser to the immersion condenser. The distribution manifolds are adapted to be fluidly coupled to the server liquid cooling loops.

    摘要： An electronic rack includes one or more servers, where each server is contained within a respective server container, and each server is at least partially submerged in two-phase liquid coolant, where, while the server generates heat that is transferred to the two phase liquid coolant thereby causing some of the two phase liquid coolant to turn into a vapor. The electronic rack includes a condenser container and condensing coils mounted at a top portion of the electronic rack to condense the vapor into the two-phase liquid coolant. The electronic rack includes a vapor manifold along a length of the electronic rack, the vapor manifold coupling the condenser container to a respective server, where the vapor manifold carries the vapor from the servers to the condensing coils. The electronic rack includes a first return line coupled to the condenser container, to return the two-phase liquid coolant to a coolant unit.

    摘要： A connector assembly may include a plate to be attached to a server chassis of an electronic rack; a connection module; and a moveable alignment module having a guiding structure and configured to be coupled to the plate via the connection module. The moveable alignment module may house one or more fluid blind mate connectors that fluidly connect to one or more cold plates that are thermally coupled to one or more electronic server components of the server chassis. The connection module may enable the moveable alignment module to be moveable when the guiding structure engages a distribution manifold of the electronic rack to align and couple the one or more fluid blind mate connectors to either at least one of a supply line connector or a return line connector of the distribution manifold, thereby enabling fluid communication between the server chassis and the distribution manifold.

    摘要： A cooling plate includes a fluid inlet port, a cooling enclosure, and an inlet channel coupled between the fluid inlet port and the cooling enclosure to channel a two-phase fluid entering from the inlet port to the cooling enclosure. The cooling enclosure includes a number of heat spreading structures coupled to an inner surface of the cooling enclosure to form spacings, where the two-phase fluid in contact with the heat spreading structures causes portions of the two-phase fluid to change into a vapor phase. The cooling plate includes an extended vapor channel coupled to the cooling enclosure to collect the two-phase fluid in vapor phase. The cooling plate includes a vapor outlet port coupled to the extended vapor channel for the two-phase fluid in vapor phase to exit the vapor outlet port, where the cooling plate is submersible in an immersion tank containing a single-phase immersion fluid.

    摘要： According to one embodiment, during a first planning cycle, a first lane boundary of a driving environment perceived by an ADV is determined using a first lane boundary determination scheme (e.g., current lane boundary), which has been designated as a current lane boundary determination scheme. A first trajectory is planned based on the first lane boundary to drive the ADV to navigate through the driving environment. The first trajectory is evaluated against a predetermined set of safety rules (e.g., whether it will collide or get too close to an object) to avoid a collision with an object detected in the driving environment. In response to determining that the first trajectory fails to satisfy the safety rules, a second lane determination boundary of the driving environment is determined using a second lane boundary determination scheme and a second trajectory is planned based on the second lane boundary to drive the ADV.
