Abstract: A power heat dissipation device includes a heat-conducting layer, a heat sink and at least one thermoelectric cooling chip. The heat-conducting layer has a heat-absorbing-surface and a heat-dissipating-surface which are opposite to each other. The heat sink is in thermal contact with the heat-dissipating-surface of the heat-conducting layer. The at least one thermoelectric cooling chip is embedded in the heat-conducting layer. The heat-conducting layer has an effective heat-conducting-region. A1 is the area on the heat-absorbing-surface which the effective heat-conducting-region projects on, and A2 is the area on the heat-absorbing-surface which the thermoelectric cooling chip projects on. The ratio of A2 to A1 is between 0.15 and 0.58.

Abstract: This invention provides a digital microfluidic manipulation device and a manipulation method thereof. This device comprises a PDMS membrane having a surface comprising a plurality of hydrophobic microstructures; a plurality of air chambers arranged in an array and placed under the PDMS membrane; and a plurality of air channels, each of which connects to a corresponding one of the plurality of air chambers. When a suction force is transmitted via one of the plurality of air channels to the corresponding air chamber, a portion of the PDMS membrane above the air chamber deforms toward the air chamber, so that the surface morphology and the contact angle of the liquid/solid interface of the surface comprising the plurality of hydrophobic microstructures are altered and thereby to drive droplets.
