A cooling system for an information handling system comprises a fan with a sunflower type heat exchanger having two heat exchanger bodies separated by a gap and rotationally offset an angle sized such that a fin of the first heat exchanger body is aligned relative to a channel between two adjacent fins of the second heat exchanger body. As airflow flows through channels between adjacent fins of the first heat exchanger body, the air temperature increases. Air exiting the first heat exchanger body mixes with a second airflow entering the gap between the two heat exchanger bodies and the combined airflow is cooler and turbulent for additional heat absorbing capability for improved cooling.

An apparatus and kit for capturing waste air flow wherein the apparatus comprises a shroud locatable over the waste airflow source, a first fan rotatably mounted within the should and a first electrical generator motor operably connected to and driven by rotation of the first fan, wherein the first fan is rotatable in a first direction by the waste air flow. The kit further comprises a second fan sized to correspond to and replace an existing axial fan.

Reverse flow microstructure water cooling unit for cooling of an electrical or electronic component which already includes an electrical pump which is placed above the middle of the bottom plate sucking the water out of the bottom micro fin cross structure and thereby generates micro turbulences which improve the cooling capability of the whole water cooling unit.

A turbulence member is made of a flat plate member configured to be inserted into a heat-transfer tube having a substantially elliptical cross-sectional shape. The flat plate member is a generate turbulence in a fluid flowing inside the heat-transfer tube by a plurality of projected pieces projected on both front and back surfaces. A rotation preventing piece configured to prevent rotation of the flat plate member inside the heat-transfer tube is provided in at least one of both side edges along the flow passage direction in the flat plate member. The rotation preventing piece is provided at a predetermined angle to the flat plate member so that a forefront comes into contact with a tube wall inner circumferential surface of the heat-transfer tube. A space through which the fluid can circulate is formed between the rotation preventing piece and the tube wall inner circumferential surface.

A heat exchanger for a vehicle includes an inlet tank configured to receive air from an air circuit of the vehicle. The heat exchanger further includes a heat exchange assembly disposed intermediate the inlet tank and an outlet tank. The heat exchange assembly exchanging heat between the air and a coolant. The outlet tank is configured to directly couple to an engine block of the vehicle and convey the air to the engine block. The outlet tank has at least two openings formed therein. The openings are configured to communicate with corresponding cylinders of the engine block of the vehicle.

A passive vortex formed or induced from a temperature difference across a cavity or void aggregates and supports a horizontal flow over the top of the cavity. A cavity of a suitable depth and width exhibits a small difference in temperature, or heat source, along the sides or bottom of cavity. A resulting convective flow tends to form a rising current along a warmer side, and a complementary downward current on an opposed side of the cavity. The formed vortex tends to draw the cooler downward flow across the warmer, heated surface, enhancing the vortex flow. The vortex aligns with a horizontal flow across the top of the cavity as the upward current complements the downward current on an opposed side of the cavity. A plurality of adjacent cavities tend to align with an aggregate horizontal flow contributed from each cavity.

A heat sink for location in a fluid flow, including a heat sink base and a plurality of heat dissipating elements, such as elongate fins, extending from the surface of the heat sink base. In certain arrangements the heat sink is provided with a diversion flow passageway for diverting a fraction of fluid flow away from the heat dissipating elements. In other arrangements there may be two arrays of elongate fins laterally offset. In yet a further arrangement the heat sink may be configured to promote the generation of at least one vortex.
