Abstract: A window type air conditioner comprises: an indoor unit mounted inside a case positioned at the indoor side thus to be heat-exchanged with the indoor air; an outdoor heat exchanger mounted inside a case positioned at the outdoor side thus to be heat-exchanged with the outdoor air; and an outdoor cross flow fan for generating a blowing force so that the out-door air can pass through the outdoor heat exchanger and for sucking the outdoor air in a circumferential direction thereof and thereby discharging the outdoor air in the circumferential direction thereof. According to this, noise is lowered, the air volume lowering due to a channel resistance is prevented, and the entire size of the air conditioner is minimized.

Abstract: A window type air conditioner comprises: a case (10) of which one side is positioned at an indoor side and another side is positioned at an outdoor side; an indoor heat exchanger (22) mounted inside the case positioned at the indoor side thus to be heat-exchanged with the indoor air; an indoor centrifugal fan (24) opposite to the indoor heat exchanger for generating a blowing force so that the indoor air can pass through the indoor heat exchanger; an outdoor heat exchanger (32) mounted inside the case positioned at the outdoor side thus to be heat-exchanged with the outdoor air; and an outdoor centrifugal fan (34) opposite to the outdoor heat exchanger for blowing the outdoor air by a centrifugal force. According to this, an air volume lowering due to a flow channel resistance is prevented at the time of sucking and discharging the outdoor air, and the entire size of the air conditioner is reduced.

Abstract: A window type air conditioner comprises: a case of which one side is positioned at an outdoor side and another side is positioned at an indoor side; an axial fan mounted in the case, for blowing air in a radius direction thereof; an outdoor heat exchanger for heat-exchanging outdoor air blown by the axial fan; and a shroud having the outdoor heat exchanger therein, for guiding the air blown by the axial fan, wherein an inclination surface is formed at an edge of the shroud in order to smoothly flow air introduced in a radius direction. According to this, a flow resistance of air is minimized and an air volume is increased.

Abstract: A window type air conditioner comprises: a case having an indoor air suction port for sucking indoor air and an indoor air discharge port for discharging heat-exchanged air indoors; an indoor unit mounted inside the case positioned at an indoor side thus to be heat-exchanged with indoor air, and an outdoor unit mounted inside the case positioned at an outdoor side thus to be heat-exchanged with outdoor air, in which the indoor air suction port is formed at a front surface of the case and the indoor air discharge port is formed at an inclination front surface between the front surface and an upper surface of the case. According to this, indoor air smoothly flows thus to increase an air discharge amount, and a flow resistance is decreased thus to reduce noise.

Abstract: A heat exchanger for a dryer includes a plurality of tube units configured to conduct warm humid air and a plurality of fin units configured to conduct a flow of ambient air. The tube units and fin units are alternately stacked to form a core. The fin units includes a plurality of air channels formed by repeatedly bending a flat metal plate in a zigzag fashion and a plurality of fins formed on surfaces of the air channels. The tube units have a duct form with both ends opened. The tube units may be formed by extrusion. A plurality of channel walls can be formed inside the tube units. A plurality of grooves or fins can also be formed inside the tube units. A plurality of channel walls can also be vertically formed inside the tube units. In this case, the grooves or fins can be formed on the channel walls. The grooves or fins can also be formed in a spiral form on the inner surfaces of the tube units.

Abstract: A heat exchanger for a dryer includes a plurality of tube units in which wet air is circulated, and a plurality of fin units alternately laminated with the plurality of tube units, in which external air flows. The tube and fin units are bonded to one another at contact portions by a cladding material interposed therebetween. The cladding material is formed of a material having a melting point lower than the melting points of the tube and fin units. The cladding material can be a metallic material including aluminum or aluminum alloy. A very thin layer of cladding material helps to increase the heat transfer efficiency of the device. Likewise, using a cladding material with good thermal transfer characteristics helps to improve the heat transfer efficiency of the device. Bonding the tube units to the fin units using such a cladding material can reduce the fabrication cost and fabrication time compared to heat exchange units where the bonding is done with an epoxy.

Abstract: A heat exchanger for a dryer includes a core in which a plurality of tube units and a plurality of fin units are alternately stacked. Front and rear covers are attached at front and rear sides of the core. A front plate is positioned between the core and the front cover and a rear plate is positioned between the core and the rear cover. The plates have openings at locations corresponding to the opened ends of the tube units. The plates are physically coupled with the front and rear covers. The plates are also attached to the core with a cladding material by a brazing operation.

Abstract: A heat exchanger for a dryer includes a plurality of tubes for circulating wet air and a plurality of fin structures for circulating external air which are alternately laminated together to form the heat exchanger. The fin structure includes a plurality of air passages formed by repeatedly bending a flat-type metal plate in a zigzag form. A plurality of fins are formed on side surfaces of the air passages. The fins protrude from the side surfaces of the air passages at an inclination angle. The fins are formed by partially cutting the plate forming the side surfaces of the air passages, and by the bending the cut portions of the plate into the air passages to from the fins. A heat transfer area and a heat transfer efficiency are increased, thereby enhancing a drying efficiency of a dryer having the heat exchanger.
