There is provided a water purifying filter assembly module that a water purifying filter can be easily released from or assembled with. The water purifying filter assembly module may include: a filter assembly head having a water purifying filter assembled on one side thereof, the filter assembly head configured such that water to be filtered flows into the water purifying filter and the water, filtered through the water purifying filter, is discharged to an outside thereof; and a module body having the filter assembly head rotatably provided therein, the water purifying filter being released from or assembled on the filter assembly head as the water purifying filter is aligned and rotates with the filter assembly head.

Water purifying filter assembly module

Disclosed is a filter assembly including a filter cartridge including a housing, a filter provided inside the housing, and a cartridge connection portion provided at an upper portion of the housing, a head portion including a head connection portion to be coupled to the cartridge connection portion so that the filter cartridge can be attached and detached, a water inlet which introduces water to the filter cartridge, and a water outlet which discharges the water filtered by the filter cartridge, the head portion including a filter attaching and detaching lever which is movable between a first position, at which the head connection portion and the filter cartridge connection portion are coupled to each other, and a second position, at which the head connection portion and the filter cartridge connection portion are separated from each other, and can be supported by the head portion.

Filter assembly

A heat exchanger is disclosed including a plurality of plate fins which are disposed in parallel at a predetermined interval and between which air flows; heat transfer tubes through which fluid runs; and a plurality of strips formed on the fins between nearby heat transfer tubes, the strips being divided into first strips formed on a center line connecting the centers of the nearby heat transfer tubes, and second strips opposingly disposed centering on the center line and formed along an ellipse having the center line in the direction of the line of apsides.

Heat exchanger

A heat exchanger structure is disclosed including: a plurality of heat exchange fins stacked at predetermined intervals for enhanced thermal conduction; heat transfer tubes perpendicularly penetrating the heat exchange fins so that coolant conveyed there through is heated or cooled; an intake side in which a plurality of slits are cut and raised from a reference surface of the fin in a central portion between the heat transfer tubes with angled edges so that air is directed to the heat transfer tube; and an outlet side having raised slits whose edges are disposed at a larger angle than the intake side, increasing the velocity of air flow passing through the periphery of the heat transfer tube to enhance heat exchange and thereby prevent the flow from being stagnated at the rear of the heat transfer tube.
