Techniques are described for managing temperature in an autonomous vehicle. An exemplary method comprises performing autonomous driving operations that operate the autonomous vehicle in an autonomous mode, receiving one or more messages from a temperature sensor associated with an electrical device located on or in the autonomous vehicle while the autonomous vehicle is operated in the autonomous mode, determining a cooling technique to reduce the temperature of electrical device, and performing the cooling technique.

A method comprises performing an analysis of airflow and temperature distribution in an indoor environment utilizing a hybrid turbulence model including a Chen-Xu model used for analysis of bulk flow and a wall function used in first grid cells bounding solid objects in the indoor environment and adjusting physical layout and/or operating parameters of heat producing electrical equipment and/or a cooling system of the indoor environment responsive to results of the analysis to improve one of temperature distribution within the indoor environment and operating efficiency of the cooling system of the indoor environment.

The present disclosure is directed to examples of modular data centers configured to provide cooling to liquid-cooled electronics equipment stored within the modular data centers. In one aspect, a modular data center can be configured to provide cooling without requiring the use of mechanical refrigeration (e.g. vapor-compression or absorption refrigeration), through the use of a dry cooler in combination with an optional evaporative cooler.

A rollable display device includes: a rollable display including a first end and a second end spaced apart from the first end; a first slider including a roller that supports the first end of the rollable display, the first slider being configured to roll the rollable display about the roller; and a second slider including a support that supports the second end of the rollable display while bending the second end of the rollable display, the second slider being slideable relative to the first slider.

An apparatus can be employed as a mobile wireless order point and pick-up station. The apparatus can be configured to house a display device and to allow the display device to be used in many different locations for the purpose of receiving and/or picking up orders. To facilitate its mobility, the apparatus can include an integrated pallet jack and be configured with wireless communication capabilities and a portable power source. The apparatus may also include a retractable awning which can serve to provide shading to the display device to facilitate its use and to reduce heating when the apparatus is used in an outdoor environment.

A display device includes a display module having a display region and a non-display region, and a window module disposed on the display module. The window module includes a thin glass substrate, a window protective layer disposed on the thin glass substrate, and a bezel pattern disposed on a surface of the thin glass substrate or disposed on a surface of the window protective layer. The bezel pattern overlaps the non-display region. The edge of the thin glass substrate does not overlap the bezel pattern in a plan view, and the edge of the thin glass substrate is not aligned with the outer edge of the bezel pattern in a plan view.

A thermal management system for an enclosure containing electrical components includes a cooling unit for controlling temperature inside the enclosure and a controller for the cooling unit, the controller being configured so that it can receive a three-phase power input signal and distribute power and control connected components using the three-phase signal. The controller can protect the compressor in critical scenarios such as thermal overload and overcurrent. The controller can output various faults such as missing phase alarm, imbalance phase alarm, overcurrent alarm, thermal overload alarm, door open alarm, and temperature and pressure alarms. An auto phase sequence correction controls the phase relay, accepting 3 phase 480 VAC power input from facility power terminal, supplying 3 phase power to the compressor and motor impellers, 12V DC power to a display unit, and 24V DC power to a remote access control module.

The power conversion device includes: a main circuit having first and second wiring layers formed respectively on both surfaces of a base board, mounted parts mounted on the first and second wiring layers, and first and second GND layers formed respectively, between external- and internal-layer portions of the base board and in regions corresponding to the mounted parts each being a mounted part which forms a circuit other than a circuit having an inductance component as a lumped constant, and to the first and second wiring layers; and a cooler attached to the base board by means of fixing screws through a first through-hole created in an end portion of the board; wherein the first and second GND layers are each formed so that creepage distance is created around a second through-hole in which a lead insertion part that mutually connects the first and second wiring layers is inserted.

An electronic device includes a top plate having a first surface and a second surface that is positioned at an elevation that is lower than an elevation of the first surface, the second surface extending from a first end part of the top plate to a second end part of the top plate, a bottom plate provided under the top plate, and a circuit board placed between the top plate and the bottom plate and mounted with an electronic component. The top plate has opposing first and second edges and opposing third and fourth edges that are perpendicular to the first and the second edges, the first end part being formed at the first edge and the second end part being formed at the second edge.

Heat sink and heat sink arrangements are provided for an electronic device immersed in a liquid coolant. A heat sink may comprise: a base for mounting on top of a heat-transmitting surface of the electronic device and transferring heat from the heat-transmitting surface; and a retaining wall extending from the base and defining a volume. A heat sink may have a wall arrangement to define a volume, in which the electronic device is mounted. A heat sink may be for an electronic device to be mounted on a surface in a container, in an orientation that is substantially perpendicular to a floor of the container. Heat is transferred from the electronic device to liquid coolant held in the heat sink volume. A cooling module comprising a heat sink is also provided. A nozzle arrangement may direct liquid coolant to a base of the heat sink.
