Specifically, each half wave of the heat dissipation portion 11 extending in a wave shape can be used as a fin, the crest of the half wave abuts against a cavity wall 21, and the connecting position of two adjacent half waves can be used as a trough, and the trough abuts against another cavity wall 21. The heat dissipation portion 11 of this embodiment extends in a wave shape along the second direction y, which can increase the contact area between the heat dissipation portion 11 and the heat exchange cavity 20, thereby enhancing the heat exchange performance of the heat exchanger. Among them, the two clamping portions 12 are respectively located at the two ends of the heat dissipation portion 11, and the cross-section where the heat dissipation belt 10 is connected to the cavity wall 21 and the side wall 22 of the heat exchange cavity 20 has a bow-tie feature, which can make the side wall 22 in close contact with the clamping portion 12 and limit the displacement of the heat dissipation belt 10.
