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 support assembly for attaching a heat exchanger to a frame of a machine. The support assembly includes a clip configured to at least partially surround a perimeter of a tube member of the heat exchanger. The clip includes a first end portion and a second end portion configured to engage the first end portion to hold the support assembly around the tube member in a closed position. The first end portion includes a laterally-extending projection and a laterally facing surface spaced apart from the projection by a recessed area. The second end portion defines a recess configured to receive a portion of the projection.

A plurality of spacer devices for incorporation into a bent-tube heat exchanger that includes a spine and one or more fingers that protrude from opposite sides of the spine. The fingers are configured to exert a force against the tubes and to provide and maintain a separation between the tubes in the folded region. A heat exchanger includes a plurality of the spacer devices, such that one spacer device is positioned on every two tubes. The tubes may also include a coating in the folded region in order to reduce corrosion and increase the life-time of the heat exchanger. The method of forming the heat exchanger includes placing one of the spacer devices on every other tube, such that the fingers lay on the tubes in the region to be folded and assist in the folding process.
