Abstract: A refrigerator includes: a refrigerator body having a cooling chamber for storing food items and a mechanic chamber provided at one side thereof; a heat exchanger disposed in the mechanic chamber and performing heat exchanging while a refrigerant passes therethrough; a cross flow fan disposed facing the heat exchanger and blowing air for heat exchange; and a compressor mounted inside the mechanic chamber and compressing a refrigerant. A space for the mechanic chamber can be reduced, and thus, a cooling chamber for keeping food items can be enlarged.

Abstract: A heat exchanger comprising a plurality of refrigerant pipes bent many times for passing a refrigerant for heat exchange; and cooling fins arranged at an outer circumference surface of the refrigerant pipes for expanding a contact area of air which passes through the refrigerant pipes, wherein a direction that the refrigerant pipes are bent is a major axis and a perpendicular direction to the major axis is a minor axis. In the heat exchanger, a bending portion of the refrigerant pipe is prevented from being distorted thus to have a smooth refrigerant flow and enhance a heat exchange performance.

Abstract: A defroster for a heat exchanger includes a heat transfer plate on the heat exchanger; a thin film heater arranged on the heat transfer plate; and a power supply wire connected to the film heater for supplying power to the film heater. The defroster can be fabricated by forming a masking layer with a certain shape on an electrically resistant substrate; patterning a thin film heater on the substrate based on the shape of the masking layer; adhering the film heater to a heat transfer plate; and connecting a power supply to the film heater. Accordingly, it is possible to improve a defrosting performance of the heat exchanger and use an environment-friendly, alternative refrigerant with the relatively, low temperature defroster of the heat exchanger.
