A radiator includes a plurality of first pipe bodies. The first pipe bodies are mutually connected to form a first annular structure. The first pipe bodies are configured to allow a cooling fluid to flow through. Each of the first pipe bodies has a width and a height perpendicular to each other. The height is longer than the width.

The invention relates to a heat exchanger for an electrical machine. The heat exchanger comprises a housing and a tube bundle. The tube bundle comprises a plurality of tubes within the housing extending between a first end and a second end of the housing in the direction of the length of the heat exchanger. The housing comprises a top wall, end walls extending in the direction of the width of the heat exchanger and first and second side walls extending in the direction of the length of the heat exchanger and a bottom frame. Between a first side wall of the housing and a side of the tube bundle is a mounting space for receiving one or more cooling fluid circulating devices.

A cooling plate that includes: a plate that is attached to a heat generating element; feed flow paths and return flow paths for coolant that are alternatingly arranged along a plate face of the plate; and a plurality of coolant flow paths that are formed in a plurality of levels within the plate closer to the heat generating element than the feed flow paths and the return flow paths, the plurality of coolant flow paths placing adjacent paths of the feed flow paths and the return flow paths in parallel communication through each of the levels.

Some embodiments of the present disclosure provide a heat exchanger, including: at least three heat exchange tube groups, herein the heat exchange tube groups are communicated in sequence, and at least two heat exchange tube groups are superposed mutually along a direction in which a heat exchange airflow flows, a medium sequentially flows through each heat exchange tube group and forms a U-shaped trajectory; an intermediate adapter portion, herein at least two heat exchange tube groups are communicated with each other by means of the intermediate adapter portion, the intermediate adapter portion includes at least two adapters and an adapter tube communicated with the two adjacent adapters, herein the adapter is composed of a first plate and a second plate, the adapter tube is an extrusion-formed flat tube, and a width direction of the adapter tube is perpendicular to a width direction of the heat exchange tube groups.

A first angle formed by the header flow path with respect to a virtual connection plane between the header flow path and the plurality of branching flow paths is less than a second angle formed by the branching flow paths with respect to the connection plane.

A spiral finned condenser is provided, which comprises: a condensing pipe and a fin; the fin is spirally wound on a surface of the condensing pipe; the condensing pipe forms a cubic structure by means of a plurality of turns and bends. The condenser further comprises a fixing bracket which is clamped and fixed on the condensing pipe. The condenser has the advantages of having a small size, a compact structure and good cooling effects.

A slanted heat exchange system and method for use in aerodynamic vehicle and for transferring heat between a coolant and a fluid. In some examples, the aerodynamic vehicle is an aircraft, and the fluid is air. The slanted heat exchange system and method include a slanted heat exchanger that is slanted relative to a channel direction just before the slanted heat exchanger. The slanted heat exchanger has an increased frontal surface area while still preserving a relatively compact cross-sectional area when viewed from the front. An array of inlet turning vanes both diffuse and slow down the fluid while also turning the fluid to enter the slanted heat exchanger approximately perpendicular to the slanted heat exchanger. This mitigates turning losses and reduces any pressure drop across the heat exchanger. In some examples, an array of outlet turning vanes turns and accelerates the fluid exiting the slanted heat exchanger.
