A thermal device comprising a fluid circulation circuit in which the fluid circulates over time at different temperatures, and a thermal store and heat exchanger arranged on said circuit and enclosing an interior volume in which the fluid circulates, and in which are arranged elements that store and release thermal energy, of PCM type, in contact with the fluid, for heat exchanges. The interior volume of the store and heat exchanger is provided with baffles.

This relates to a unit for storing and releasing thermal energy including a plurality of blocks (3) each having a body (330) the lateral walls of which delimit a chamber (7) suited to receiving storage and release elements (13) of PCM type, to be placed in heat exchange relationship with a refrigerating or heat-transfer fluid (9) circulating between the chambers via passages; and elements (19) for the thermal management of the chambers arranged around said chambers and at least some of which include a thermally insulating material and others a PCM.

Methods and systems are provided for a cooling device connected to components of a motor vehicle. The cooling device influencing a fluid flow moving past the vehicle components. In one example, a system may include a cooling device positioned below an oil sump. The cooling device may feature an apparatus such that a fluid flows between the apparatus and oil sump. The cooling device may also be positioned below a transmission housing.

A heat exchanger includes a heat exchanger body arranged along an axis and having an external surface in contact with a surrounding first fluid. The body defines a first fluid passage centered on and extending along the axis. The body also defines a second fluid passage extending parallel with respect to the axis and spaced away from the axis by a second passage distance, and a third fluid passage extending parallel with respect to the axis and spaced away from the axis by a third passage distance. The first, second, and third passages are parallel to one another, while the third passage distance is greater than the second passage distance. Each of the first and third passages is configured to accept a flow of a second fluid and the second fluid passage is configured to hold a volume of air to thermally insulate the first passage from the third passage.

A transmission side cover assembly includes a transmission side cover carrying completely there on one or more filters and/or a cooler. Fluid flow channels are formed integrally in the material of the cover and provide fluid flow communication paths to the filters and/or cooler carried by the cover. The filters and/or cooler carried by the cover are accessible externally of the cover, for servicing thereof without removing the cover.

An internal combustion engine having a crankcase and a cylinder head is provided. The internal combustion engine includes at least one cylinder block, at least one cooler, at least one smooth flange surface for accommodating the at least one cooler, at least one coolant inlet to the cooler, at least one coolant outlet from the cooler, at least one exhaust gas inlet to the cooler, at least one integrated exhaust gas feed-through from the cooler and at least one internal cooling section.

An object of the present invention is to simplify portions of an oil supply passage which portions are formed at a cylinder block. An oil supply device according to the present invention includes a cylinder block, an oil pan, an oil pump, and an oil filter. Wall portions of the oil pan are coupled to wall portions of the cylinder block. An oil filter is attached to the oil pan. An upstream oil supply passage through which the oil filtrated by the oil filter flows is formed at the oil pan. A downstream oil supply passage including a main gallery extending in a cylinder column direction is formed at the cylinder block. A first communication passage through which the main gallery and the upstream oil supply passage communicate with each other is formed at the wall portion of the cylinder block and the wall portion of the oil pan.

An aircraft engine oil distribution system includes a system container, an oil reservoir disposed in the system container, the oil reservoir having a plurality of fins protruding from an inner-surface of a wall of the oil reservoir and extending into the oil reservoir, and a heat exchanger disposed in the system container. The heat exchanger includes a cooling fluid passage defined at least between the one or more walls of the system container and the sidewall of the oil reservoir, a matrix disposed in the cooling fluid passage in heat transfer relationship with the plurality of fins of the oil reservoirs.

One embodiment of an oil heat exchanger may be configured with two fluid couplers fluidly connected to a fluid conduit. The fluid conduit may be engaged with an exchange area. In one illustrative method of use the oil heat exchanger may be positioned within and secured to an oil pan of an internal combustion engine.

An engine assembly includes an oil pan including an oil pan body defining a cavity. The oil pan body includes a dividing wall separating the cavity into a first compartment and a second compartment. The engine assembly further includes a drip tray coupled to the oil pan body. The drip tray is disposed over the second compartment and can direct oil to the first compartment where the oil is warmed up initially in order to minimize the time it takes to heat the oil when the internal combustion engine is warming up. The engine assembly further includes an oil scraper coupled to the oil pan body. The oil scraper is disposed over the drip tray and can scrape oil from a crankshaft.
