The present disclosure provides a heat exchanger, including: a plurality of flat pipes, wherein, the plurality of flat pipes are arranged at intervals; first sealing cushion blocks, arranged between two adjacent flat pipes, wherein the first sealing cushion blocks are located on end portions of the flat pipes, so as to seal gaps between two adjacent flat pipes by means of the first sealing cushion blocks; and a flow collecting shell, provided with a first opening portion, wherein at least part of the first sealing cushion blocks and the end portions of the flat pipes are all plugged into the first opening portion, so that the flow collecting shell, the flat pipes and the first sealing cushion blocks form a flow collecting channel in an encircling manner.

Some embodiments of the present disclosure provides a heat exchanger, including: a plurality of flat pipes disposed at intervals, wherein the flat pipe is provided with an inlet portion and an outlet portion, and both the inlet portion and the outlet portion are located on a first end of the flat pipe; a first sealing cushion block, disposed between two adjacent flat pipes; and a flow collecting portion, provided with a first opening portion and a second opening portion, wherein the first opening portion is disposed opposite to the inlet portion, and the second opening portion is disposed opposite to the outlet portion. The first sealing cushion block includes a first sealing portion and a second sealing portion.

A header for a heat exchanger includes a header frame defining an opening and including a base portion circumscribing a perimeter thereof. A mounting tab extends from the base portion. The mounting tab is configured to bend inwardly with respect to the header frame. A deformation featured is formed on one of an inner surface and an outer surface of the header frame and is configured to facilitate bending of the mounting tab

A method of forming an assembly between a panel and a tube includes forming a hole in the panel, where a diameter of the hole is smaller than an outer diameter of the tube, and preforming a first end of the tube to conceal the hole of the panel. A diameter of the preformed portion is greater than the diameter of the hole and the outer diameter of the tube. The method further includes aligning a second end of the tube with the hole of the panel, followed by inserting the tube into the hole by application of axial force on the tube until the preformed first end of the tube abuts a periphery of the hole of the panel. The method also includes achieving an interference fit between the hole of the panel and the tube.

A heat exchanger and methods of manufacturing and assembling a heat exchanger, and more particularly to an air-flow heat exchanger having a mechanically assembled header for use in a motor vehicle. The heat exchanger comprises an all-metal bonded matrix including a plurality of substantially parallel metallic tubes and a plurality of metallic fins. The tubes have a heat transfer portion that is elongate in cross-sectional shape, and which comprises two opposing, longer sides, and two opposing shorter sides. At least one of the tubes is mechanically joined at a first end portion thereof to a first header of the heat exchanger by at least one compliant member. The compliant member extends around the first end portion of the tube to provide a seal and to permit relative movement between the mechanically joined tube and the first header due to thermal expansion and contraction of the matrix.
