Abstract: A heat exchanger is configured to be arranged on a first housing of an electronic device, wherein the first housing has a top surface and a sidewall neighboring on the top surface, wherein the first housing has multiple first metal sheets protruding from the sidewall of the first housing. The heat exchanger includes a second housing configured to be mounted to the first housing, wherein a first opening is at a bottom of the second housing and configured to have the electronic device extend into an inner space in the second housing through the first opening, and a second opening is at a wall of the second housing and communicates with the inner space. The heat exchanger includes multiple second metal sheets in the inner space, wherein the second metal sheets are configured to be arranged over the top surface of the first housing, and a first heater in the inner space and thermally connected to the second metal sheets.

Abstract: A power generating device utilizing oscillating water for converting into wave power (1) includes: a power generating tank (10) formed with a first chamber (11), a second chamber (12) and a communicating hole (13); a quantitative liquid (20) filled in the first chamber (11) and the second chamber (12); a resonating member (30), having one end communicated with the first chamber (11) and the other end disposed in a wave (2); a quantitative gas (40) filled between the first chamber (11) and the resonating member (30); and a driving member (50, 50?, 50?) pushed by the quantitative liquid (20). Accordingly, during the reciprocal movement of the wave (2), the quantitative gas (40) is pushed and squeezed thereby enabling the quantitative liquid (20) to push the driving member (50, 50?, 50?) so as to generate power.

Abstract: A power generation apparatus (1, 1a) using wave energy conversion by gravity includes a sealed body (10, 10a), a rotor (20, 20a), a gear box (30,30a), a power generation motor (40, 40a), and a pontoon (50, 50a). The rotor (20, 20a), disposed in the sealed body (10, 10a), includes an eccentric disk (21, 21a), a plurality of rollers (22, 22a) and a rotating shaft (23, 23a) penetrating through the eccentric disk (21, 21a). A center of gravity of the eccentric disk (21, 21a) is disposed with an offset to that of the sealed body (10, 10a). The gear box (31) is driven by the rotating shaft (23, 23a). The power generation motor (40, 40a) is driven by the gear box (31) to rotate and generate electric power.
