A heat exchanger for exchanging heat between first and second fluids, comprising first fluid channels extending in a longitudinal direction for carrying a first fluid, and second fluid channels extending in the longitudinal direction for carrying a second fluid, wherein the first and second fluid channels are arranged in an alternating pattern such that each of a plurality of the first channels is located laterally between second channels and each of a plurality of second channels is located laterally between first channels, and wherein the second fluid channels extend longitudinally beyond ends of the first fluid channels, and have ends that decrease in cross section such that the first fluid is able to pass around and between the ends of the second channels.

A heat exchanger is provided. The heat exchanger provides a first plurality of tubes and a second plurality of flow passages which furcate near one of the first and second manifolds into two or more furcated flow passages and subsequently converge to exit the heat exchanger. The plurality of furcated flow passages are intertwined, reducing the distance between flow passages containing each fluid therebetween to improve thermal transfer. Further, the furcations create changes of direction of the fluid to re-establish new thermal boundary layers within the flow passages to further reduce resistance to thermal transfer.

A header duct and method of forming a header duct includes an inlet portion having a planar inlet, an outlet portion have a plurality of planar outlets, and a transition portion extending continuously from the inlet portion to the outlet portion. The transition portion has a bend and internal topography defining a non-monotonic cross-sectional area distribution between the inlet and outlet portions. The transition portion can further include a bulbous region extending in a lateral direction of the duct and a protrusion located along an inside radius of the bend.

The primary fluid channel includes a fluid port and a first branched region distal to the fluid port. The plurality of secondary fluid channels are fluidly connected to the primary fluid channel at the first branched region. Each of the plurality of secondary fluid channels includes a first end and a second end opposite the first end. Each of the plurality of secondary fluid channels extends radially from the first branched region at the first end and has an equal length from a center of the first branched region to the second end.

A heat reservoir including a housing, first reservoir elements for storing thermal energy, and an inlet port is provided. The first reservoir elements are arranged in the housing. The inlet port is coupled to the housing in such a way that a working fluid can flow into the housing through the inlet port. The inlet port is provided with an inlet orifice through which the working fluid can flow from the surroundings of the heat reservoir into the inlet port. The inlet port includes a diffusor portion the cross-section of which increases in the direction running from the inlet orifice to the housing.

The present disclosure relates to a heat exchanger, for example an indirect charge air cooler for an internal combustion engine. The heat exchanger includes a heat exchanger block including a first channel system for a first fluid and a second channel system for a second fluid that is fluidically separate from the first channel system. Two opposite side parts and two opposite end parts are structured and arranged to fluidically delimit the second channel system.
