A heat sink for collecting thermal energy from a heat generating component. The heat sink comprises a base comprising a thermal transfer surface configured to be placed in thermal contact with the heat-generating component, an external surface opposite from the thermal transfer surface and an inlet side of the base extending between an edge of the thermal transfer surface and an edge of the external surface and a plurality of fins extending from the external surface. The fins define a plurality of fin passages therebetween, at least one fin of the plurality of fins having non-straight longitudinal edges extending along the external surface and defining at least in part at least one non-straight fin passage.

A rack system for housing an electronic device comprising: an immersion case configured to provide housing to the electronic device, and to receive an immersion cooling liquid, wherein the immersion case includes a drainage opening, wherein the drainage opening is configured to remove at least a part of the immersion cooling liquid from the immersion case, based on a user actuated action, during a de-racking operation of the immersion case; and a rack frame configured to slidably accommodate racking and de-racking operations of the immersion case.

A rack system for housing an electronic device comprises an immersion case configured to provide housing to the electronic device. The immersion case includes a first wall, and a second wall. The first wall and the second wall define means for controlling deformation of the immersion case, such that when an immersion cooling liquid is inserted in the immersion case, the means for controlling deformation limit the deformation of the immersion case.

A rack system for use, e.g., in data centers is disclosed. The rack system includes a rack frame and a rack-mounted assembly, including an electronic device disposed within the rack-mounted assembly, the electronic device including a heat-generating component. The heat-generating component is in thermal contact with a liquid cooling block through which a channelized cooling fluid is conveyed. The electronic device is immersed in a dielectric immersion cooling liquid. The rack-mounted assembly includes a non-sealed immersion case in which the electronic device is immersed in the dielectric immersion cooling liquid, the non-sealed immersion case configured to permit the rack-mounted assembly to be individually inserted into or removed from the rack frame. Also disclosed are container-based data center modules based on the disclosed rack system, and a data center using numerous such container-based modules.

A cooling device mountable on an electronic component comprising: a body having an internal fluid conduit for allowing a heat-transfer fluid to flow therethrough. The body comprises a first surface configured for mounting on the electronic component and permitting thermal transfer therethrough; a second surface; at least one side wall extending between the first surface and the second surface; and a gasket extending along the at least one side wall or a perimeter of the first surface, the gasket configured to extend away from the body beyond the first surface in a direction transverse thereto, to fluidly insulate the first surface when the first surface is mounted on the electronic component and submerged in the immersion cooling liquid in use.

A double-drum linkage winding type hoisting system includes a first hoisting drum and a second hoisting drum. The first hoisting drum and the second hoisting drum are engaged and linked through engagement structures on outer circumferences of the first hoisting drum and the second hoisting drum or are linked through a linkage intermediate member. A first hoisting rope is wound around the first hoisting drum. A second hoisting rope is wound around the second hoisting drum. The first hoisting rope and the second hoisting rope are not connected with each other.

The invention relates to a stroke transmitter for an actuator device. The stroke transmitter comprises a first and a second conversion unit, which are mechanically connected to one another in series, wherein the first conversion unit is designed as a hydraulic conversion unit, it can be connected to an actuator on its drive side and it is connected to the drive side of the second conversion unit on its output side, wherein the second conversion unit is designed as a cable system and has an output element on its output side. The invention also relates to an actuator device comprising an actuator and a stroke transmitter mechanically connected in series with the actuator.

Simultaneously oppositely rotating sheaves, or a chain fall, has a two sheaves upon a hexagonal axle. The first sheave receives a first line clockwise and the second sheave receives a second line counterclockwise. Upon turning the axle, the sheaves handle the lines oppositely. A signal unit regulates power delivered from a power unit to at least one motor. The power unit is preferably a battery or alternatively another source. The motor turns a gearbox that engages the axle cooperating with the sheaves. The chain fall includes an anti-two block per line. Preferably, a pulley has two outer plates and two inner plates on stubs with the first line in the center and the two second lines between an inner plate and an outer plate. A first plate and a spaced away second plate contain the components of the invention in compact form for usage by a crane.

A remote controlled lift assembly includes a pair of supports is each mountable to a respective outrigger of scaffolding. A winch unit is positionable on the supports when the supports are mounted on the scaffolding and the winch unit has a cable extending downwardly therefrom. The cable is lowered or lifted when the winch is actuated. A receiver is coupled to the winch unit and the receiver is in electrical communication with the winch unit. A remote control is provided that is carried by a user and the remote control is in wireless electrical communication with the receiver. In this way the user can remotely lift and lower the cable for lifting and lowering cargo.

In a manual/automatic non-electric-connection borehole clinometer for a landslide, a clinometer probe completes borehole inclination measurement; a hoisting mechanism is connected to the clinometer probe by a pull rope; and a first tooth disc of an automatic clutch and a first tooth disc of a manual clutch are fixed to a left shaft end and a right shaft end of the hoisting mechanism respectively, a second tooth disc of the automatic clutch is fixed to a driving shaft of an electric driving mechanism and selectively meshes with or moves away from the first tooth disc of the automatic clutch, and a second tooth disc of the manual clutch is fixed to a driving shaft of a manual driving mechanism and selectively meshes with or moves away from the first tooth disc of the manual clutch.
