A heat exchanger, in particular an oil-air cooler, for heat exchange between a first fluid and a second fluid, having at least a first row and a second row of tubular elements for the first fluid, a flow channel for the second fluid between the first and second rows of tubular elements; a collection vessel at one end of the tubular elements; and a distribution vessel at the other end of the tubular elements. Guiding elements for guiding the second fluid extend along the flow channel between the outer sides of adjacent tubular elements of the first and second rows of tubular elements. At least one adjustment device is provided for adjusting the relative position of two guiding elements about a pivot axis.
A heat exchanger, for heat exchange between a first fluid and a second fluid, having at least a first row of tubular elements and a second row of tubular elements, each for passage of the first fluid, wherein a flow channel for the second fluid is formed between the first and the second row of tubular elements, with a collection vessel at the one ends of the tubular elements and with a distribution vessel at the other ends of the tubular elements, wherein guiding elements for guiding the second fluid along the flow channel extend between the outer sides of adjacent tubular elements of the first and second row of tubular elements, the guiding elements each comprising a plate part the wall thickness of which is less than the maximum cross-sectional dimension of the tubular elements connected thereto, wherein at least one adjustment device is provided for adjusting the relative position of two guiding elements about a pivot axis extending essentially in direction of the longitudinal axes of the tubular elements, wherein the flow channel comprises an input end and an output end, and main extension directions of at least two adjacent flow channels enclose an angle (γ) between each other, the angle (γ) deviating from 0°, wherein a main extension direction of a flow channel is the direction from the input end to the output end of the flow channel.
A heat exchanger, for heat exchange between a first fluid and a second fluid, having at least a first row of tubular elements and a second row of tubular elements, each for passage of the first fluid, wherein a flow channel for the second fluid is formed between the first and the second row of tubular elements, with a collection vessel at the one ends of the tubular elements and with a distribution vessel at the other ends of the tubular elements, wherein guiding elements for guiding the second fluid along the flow channel extend between the outer sides of adjacent tubular elements of the first and second row of tubular elements, the guiding elements each comprising a plate part the wall thickness of which is less than the maximum cross-sectional dimension of the tubular elements connected thereto, wherein at least one adjustment device is provided for adjusting the relative position of two guiding elements about a pivot axis extending essentially in direction of the longitudinal axes of the tubular elements, wherein the collection vessel and/or the distribution vessel in a virtual cutting plane essentially at right angles to the longitudinal axes of the tubular elements is essentially circular-ring-segment-shaped or circular-ring-shaped.
A heat exchanger, for heat exchange between a first fluid and a second fluid, having at least a first row of tubular elements and a second row of tubular elements, each for passage of the first fluid, wherein a flow channel for the second fluid is formed between the first and the second row of tubular elements, with a collection vessel at the one ends of the tubular elements and with a distribution vessel at the other ends of the tubular elements, wherein guiding elements for guiding the second fluid along the flow channel extend between the outer sides of adjacent tubular elements of the first and second row of tubular elements, the guiding elements each comprising a plate part the wall thickness of which is less than the maximum cross-sectional dimension of the tubular elements connected thereto, wherein at least one adjustment device is provided for adjusting the relative position of two guiding elements about a pivot axis extending essentially in direction of the longitudinal axes of the tubular elements, wherein holding devices are provided in order to connect adjacent tubular elements of the first or second row of tubular elements with each other via the guiding elements, wherein two wing parts protrude from the outer side of each tubular element, wherein two wing parts on adjacent tubular elements of the first or second row of tubular elements together form one guiding element for the second fluid, wherein each wing part comprises a connection element of the holding device, which together form a joint of the adjustment device, wherein spiral-shaped bent edges of the wing parts are provided as connection elements.
