摘要:
A bent heat exchanger includes a first manifold, a second manifold, and a plurality of flat tubes each being configured to communicate the first manifold with the second manifold, and fins between the flat tubes; wherein the flat tube includes a first straight section, a second straight section and a bent section connecting the first straight section with the second straight section. The bent section includes the first twisted section connected to the first straight section, the second twisted section connected to the second straight section, and the connecting section connecting the first twisted section with the second twisted section, and the connecting section of the flat tube has a substantially flat shape or a flat arc shape. In this way, the height of the bent heat exchanger can be reduced, which facilitates the installation, and such bending manner does not require to reserve a long bending radius, which can increase the length of the fined section in a case that the flat tube has a fixed length, thus the heat exchange performance of the heat exchanger can be improved.

摘要:
The present invention offers an improved axial heat exchanger for exchanging heat between a gas medium and a fluid or liquid medium. The axial heat exchanger comprises a longitudinal and substantially axially extended outer channel that is adapted to enclose a flow of a first gas medium. The heat exchanger also comprises a plurality of substantially parallel inner channels that are adapted to enclose a flow of a second liquid medium. The inner channels are arranged inside the outer channel so as to extend substantially axially along the inside of said outer channel for enabling a transfer of heat between said first gas medium and said second liquid medium. The heat transfer is improved to some extent as the number of inner channels increases and it is further improved in that at least one of the inner channels is joined with at least one elongated sheet. The sheet is arranged to extend substantially axially along the inner channel so as to substantially coincide . with the direction of flow of the first gas medium through the outer channel.
