An object of this invention is to efficiently warm up a catalyst and keep its temperature. Provided is a drive system, including: an internal combustion engine; a catalytic unit configured to purify an exhaust gas from the internal combustion engine; a motor used for at least one of drive or regeneration; and a flow path formed so as to allow an oil-based medium for lubricating the motor to flow in the vicinity of the catalytic unit. The oil-based medium is heated in the motor and exchanges heat in the catalytic unit to heat the catalytic unit.

In accordance with the principals of the present invention, a cold tube is adapted to securely surround the beverage can, the cold tube utilizing high heat capacity/thermal mass to wick heat from the beverage in the beverage can. Contained within the cold tube, a plurality of fins are provided thus acting as a heatsink. The presence of the fins act as a heatsink by increasing convective, conductive, and radiative heat dissipation if used in the absence of the cold tube and conductive heat dissipation if used with the cold tube.

A rotary cooler is provided, consisting of a plurality of transport tubes for transporting material to be cooled, wherein the plurality of transport tubes are arranged about an axis of rotation and are adapted to be filled jointly via a filling region with material to be cooled, characterized in that each transport tube is arranged substantially concentrically in a cooling tube in which a cooling medium flows and cools the material to be cooled via the wall of the transport tube. Furthermore, a method for operating said rotary cooler is provided.

A heat exchange member including: a honeycomb structure body including: partition walls extending from a first end surface to a second end surface to define cells forming flow passages for a first fluid; and an outer peripheral wall; and a covering member configured to cover the outer peripheral wall of the honeycomb structure body. The partition walls and the outer peripheral wall contain ceramic as a main component, and the outer peripheral wall surface has a peak count RPc according to JIS B 0601:2013 set to 55 pks/cm or larger.

A heat exchanger may comprise a primary fluid path comprising an outer shell enclosing a primary cavity through which a primary fluid may flow; and a secondary fluid path coupled to the primary fluid path comprising a secondary fluid supply conduit, a secondary fluid exit conduit, and a first heat transfer element coupled fluidly between the secondary fluid supply conduit and the secondary fluid exit conduit, wherein the secondary fluid path is configured such that a secondary fluid may flow through the secondary fluid supply conduit, the first heat transfer element, and the secondary fluid exit conduit, which are in fluid communication with one another. The first heat transfer element, and additional heat transfer elements, may be disposed in the primary cavity such that the primary fluid contacts a secondary outer shell of the first heat transfer element.

A heat exchanging member including a hollow pillar shaped honeycomb structure having partition walls defining cells, the cells penetrating from a first end face to a second end face to form flow paths for a first fluid, an inner peripheral wall, and an outer peripheral wall; and a covering member being configured to cover the outer peripheral wall of the pillar shaped honeycomb structure. The heat exchanging member is configured to perform heat exchange between the first fluid and a second fluid flowing through an outer side of the covering member. In the heat exchanging member, in a cross section of the pillar shaped honeycomb structure perpendicular to a flow path direction of the first fluid, the cells are radially provided, and each of the inner peripheral wall and the outer peripheral wall has a thickness larger than that of each of the partition walls.

Devices, systems, and methods are disclosed for cooling using both air and/or liquid cooling sub circuits. A vapor compression cooling system having both an air and liquid cooling sub circuit designed to service high sensible process heat loads that cannot be solely cooled by either liquid or air is provided.

Conduits for cooling a hydrocarbon stream and processes for using same. The conduit can include a first inner wall defining a first bore, a second inner wall defining a second bore, and an outer wall disposed about the first and second inner walls. The conduit can also include an annular support wall connected to an inner surface of the outer wall. An end of the second inner wall and an end of the annular support wall can define a perimeter opening that can be in fluid communication with the second bore. An annular flexible ring can be bonded to the annular support wall and can flexibly contact the first inner wall. A substantially annular cavity can be disposed between the second inner and the outer walls and in fluid communication with the perimeter opening. A quench fluid introduction port can be configured to introduce a quench fluid into the cavity.

A flow-guiding rod includes a cooling channel provided in a rod portion of the flow-guiding rod, and a coolant inlet pipe and a coolant outlet pipe provided on end(s) of the flow-guiding rod. The coolant inlet pipe and the coolant outlet pipe are communicated with the cooling channel.

A fluid heat exchanger with pump, adapted to drive a fluid for heat transfer, comprises a heat conduction unit, a diversion unit, and a housing unit. The heat conduction unit includes a heat conductor. The diversion unit includes a cover and a diversion plate. A cooling chamber is defined by the cover and the heat conductor. The cover is provided with a fluid stopper. The diversion plate is disposed in the cooling chamber, and one end of the diversion plate abuts against the fluid stopper, so that the cooling chamber is divided into an upper passage and a lower passage. The housing unit includes a housing and a pump module. The fluid in the housing is driven by the pump module to flow through the upper passage to the lower passage, and then the fluid returns to the housing to carry the heat from the heat conductor.
