摘要： Provided is a highly efficient, slim heat transfer apparatus, including a main body connected to an end of a condensing zone through a liquid coolant reservoir. An extension of the main body is connected to the other end of the condensing zone. The main body has a coolant reservoir that stores liquid coolant supplied from the condensing zone, a vaporization zone in which the liquid coolant supplied from the coolant reservoir is vaporized, and a channel region connecting the coolant reservoir to the vaporization zone. The channel region acts as a channel for supplying the liquid coolant from the coolant reservoir to the vaporization zone.

摘要： A substantially flat heat transferring device and a method of fabricating the same are provided. The device includes a lower plate, an upper plate, a wick plate, and a liquid-phase coolant, while the lower plate contacts a heat source at its bottom. The upper plate is hermetically coupled with the lower plate along its edge to form a void therebetween. The wick plate is provided between the upper plate and the lower plate and is maintained in position relative to the lower plate by surface tension of the liquid-phase coolant. The liquid-phase coolant transfers heat by circulating between a vaporization part, where the heat source is located, to a condensing part. Here, the wick plate includes a plurality of holes and a plurality of planar wicks and makes the liquid-phase coolant flow from the condensing part to the vaporization part by capillary force between itself and the lower plate.

摘要： A capillary pumped loop system includes an evaporator for vaporizing a refrigerant by absorbing heat from the periphery, a condenser for turning the vaporized refrigerant into a liquid by radiating heat from the vaporized refrigerant, a tube for forming a circulatory path connecting the evaporator to the condenser, and a capillary unit installed to form a plurality of gaps within the tube so that the refrigerant can move along the circulatory path due to capillary action caused by the gaps. Accordingly, when the refrigerant passes through the capillary unit due to the capillary action, bubbles in the tube can be reduced. In addition, a multi-path is formed for the movement of the liquid refrigerant, so discontinuation of the refrigerant can be prevented, thereby preventing the refrigerant in the evaporator from drying out.

摘要： An inkjet printhead having a bezel structure to remove ink bubbles. The inkjet printhead includes a channel plate having an ink channel, actuators formed on the channel plate to provide driving forces to eject the ink, and an ink-supply bezel coupled to the channel plate. The ink-supply bezel includes an ink reservoir that is connected to an ink inlet and stores ink that is to be supplied to the ink channel, an ink supply port through which ink is supplied to the ink reservoir, and an air discharge port through which bubbles that are removed from the ink of the ink reservoir are discharged. The ink supply port and the air discharge port can be formed closed to both ends of the top surface of the ink reservoir, respectively. The ink supply port can have a bottom end lower than that of the air discharge port. The ink reservoir can include a sloped ceiling surface. Therefore, ink bubbles can be effectively removed from the ink before the ink is supplied to the ink channel.
