A cooling apparatus for a hydrostatic transmission includes a cooling body to be coupled with a hydrostatic transmission, a sidewall member protruding from the cooling body to surround a cooling flow path which cools a working fluid supplied from the hydrostatic transmission and discharges the working fluid into the hydrostatic transmission or a storage tank, an installing member protruding from the cooling body at a position spaced apart from the sidewall member to be disposed inside the sidewall member, a detour member connected to the installing member and protruding from the cooling body to extend in a first axial direction to allow the working fluid, which flows along the cooling flow path, to make a detour, and a plurality of protruding members protruding from the cooling body to be spaced apart from each of the sidewall member, the installing member, and the detour member in the cooling flow path.

A device for heat transfer between a first fluid and a second fluid includes an assembly of tube elements for conducting the fluid and have a first, nondeformed region and a second, deformed region, disposed at an end of the tube element. A tube plate with passage apertures and a sealing element with passage apertures are provided. The sealing element is disposed between an outer surface of the second region of a tube element and an edge of a rim of the passage aperture of the tube plate. Tube elements are developed as flat tubes with flow channels. Flow channels are separated from one another by an internal structure element. A system and a method for the manufacture of the device are also provided.

An improved baffle assembly for heat exchanger tubes comprising a shaft and at least one opposing pair of expanding baffles positioned coaxially on the shaft, each expanding baffle comprising a central hub portion and a plurality of extension portions each radiating outward from the hub portion at complementary oblique angles so that the central hub portions of each baffle are spaced apart along the shaft and the distal ends of the extension portions of each baffle are brought into physical contact.

Various embodiments of the present disclosure provide a heat sink for a plug-in card and a plug-in card including the heat sink. The heat sink comprises a first part secured to a surface of the plug-in card and a second part coupled to the first part and being movable relative to the first part in a first direction, wherein the first direction is perpendicular to the surface of the plug-in card. In this way, when the second part and the first part have a larger overlap in the first direction, the heat sink has a smaller first height and when the second part and the first part have a smaller overlap in the first direction, the heat sink has a greater second height.

Proposed is a heat sink device that uses graphite sheets as fins. The heat sink device includes graphite sheet fins having a predetermined height and width in a height direction and in a width direction, the graphite sheet fins being arranged parallel to each other while being spaced a predetermined distance apart from each other in a depth direction, insert plates formed of metal material, the insert plates being disposed at one end of the graphite sheet fins in the height direction and being arranged alternately with the graphite sheet fins, and a fixing means configured to press and fix the graphite sheet fins and the insert plates while the graphite sheet fins and the insert plates are in an alternately arranged state.

A connection system for coupling a steam turbine to a condenser is provided. The connection system includes a dog-bone connector, a first clamp, and a second clamp. The dog-bone connector includes a first end, a second end opposite the first end with respect to the third direction, and a body extending therebetween. The first clamp includes a first portion, a second portion coupled to the first portion, and a first retention cavity defined therebetween. The first clamp is configured to couple to one of the steam turbine and the condenser such that the first portion is movable relative to the second portion along the third direction. The second clamp is configured to couple to the other of the steam turbine and the condenser and includes a third portion, a fourth portion coupled to the third portion, and a second retention cavity defined therebetween.

A threaded cooling apparatus includes a head having a heat exchanger and a shaft having a threaded section configured to mechanically fasten the head to a structure. The heat exchanger is configured to exchange heat with a coolant flowing through the head. The shaft also includes first and second cooling channels. The first cooling channel is configured to deliver the coolant to the heat exchanger, and the second cooling channel is configured to exhaust the coolant from the heat exchanger. The apparatus may also include a first seal between the head and the structure that is configured to reduce or prevent coolant loss. The apparatus may further include a second seal that is configured to reduce or prevent coolant flow between the first and second cooling channels that bypasses the heat exchanger.
