Provided is a heat exchanger. The heat exchanger includes: a core portion configured to have a cooling water channel provided therein; a housing configured to have a concave shape to have the core portion inserted thereinto so that the core portion is housed therein and have one side provided with an air inlet into which air is introduced and the other side provided with an air outlet through which the air is discharged; and a sealing member configured to be interposed between an outer side of the core portion and an inner side of the housing to seal between the core portion and the housing, thereby preventing air from being bypassed between the core portion and the housing to improve heat exchange efficiency and heat exchange performance.

The heat exchanger comprises a first and a second stage (E1,E2), each having an inlet and an outlet of water, the second stage (E2) having an inlet and an outlet of oil, the first stage (E1) being provided with fuel inlet and outlet nozzles, selectively connected, in parallel, to the fuel supply to the engine (M). The inlet and outlet of water of the first stage (E1) are respectively connected to the outlet of the water radiator, by means of a cooling water circuit internal to the engine (M), and to the water inlet of the second stage (E2). The water outlet of the second stage (E2) is connected to the inlet of a water radiator, and the inlet and outlet of oil in the second stage (E2) are connected in series to a lubricant oil circuit internal to the engine (M).

A heat transferring apparatus may employ a heat exchanger with a fluid inlet and a fluid outlet and be coupled to a power exchange unit, which employs a driving fan fluid inlet, a series of inner fan blades to receive the fluid from the driving fan fluid inlet, and a rotable driving fan unit. The inner fan blades are attached to the rotable driving fan unit along with driving magnets. A rotatable driven fan unit has numerous outer fan blades and a series of imbedded driven magnets. The fluid drives the inner fan blades and flows into the heat exchanger. The outer fan blades force air through the heat exchanger and cools the fluid. A power transfer wall located between the inner magnets and the outer magnets transfers magnetic fields from the inner magnets to the outer magnets to impart rotation in the driven fan unit and outer fan blades.

A stacked plate heat exchanger including a plurality of stacked plate pairs, each plate pair including first and second plates having elongate central portions surrounded by sealably joined edge portions with an elongate fluid passage defined between the central portions. Each plate pair has spaced apart inlet and outlet openings in flow communication with the fluid passage, at least some of the plate pairs having a substantially planar air-side fin plate extending peripherally outward from the joined edge portions, the fin plates of the stacked plate pairs being spaced apart and substantially parallel to each other. The fluid passage may be arranged at an angle relative to air flow direction.

A cooling system for a work vehicle (e.g., a wheel loader) having reduced air restriction noise includes a cooling system frame defining an enclosure therein. A cooler (e.g., an engine cooler) and a fan are coupled to the cooling system frame, the fan imparting a velocity on a flow of cooling air flowing through the cooler. An air deflection member is coupled to the cooling system frame and extends into the enclosure to shape the flow of cooling air as it travels between the cooler and the fan. The air deflection member defines a fluid reservoir (e.g., a hydraulic reservoir) for holding a fluid (e.g., a hydraulic fluid).

A fuel cooling system for a motorvehicle has a fuel tank for supplying fuel to a motorvehicle engine. The system further includes a refrigerant evaporator and a compressor of a refrigeration system for air conditioning, and a heat exchanger provided between a fuel pipe and an evaporated refrigerant pipe. The heat exchanger is made up of coaxial inner and outer tubes and, for example, helical heat transfer fins contained in an annular space between the inner and outer tubes. With this construction, the fuel flowing through a fuel return pipe extending between the engine and the fuel tank is caused to flow through the annular space between the inner and outer tubes. On the other hand, evaporated low temperature refrigerant is caused to flow through the inside of the inner tube of the heat exchanger. The inner tube has secured therein, heat exchange fins, for example, of the type extending longitudinally thereof and having wavy transverse cross section. The fuel and the refrigerant exchange heat through the inner tube, whereby the fuel is cooled effectively.
