Definitions

  • the present invention relates to a heat exchanger for a refrigerator.
  • a heat exchanger may be used as a condenser or an evaporator in a refrigeration cycle apparatus, which is composed of a compressor, a condenser, an expander and an evaporator.
  • a heat exchanger is mounted in a vehicle, a refrigerator or the like so as to exchange heat between refrigerant and air.
  • a heat exchanger may be classified into a fin-tube-type heat exchanger, a microchannel-type heat exchanger and the like.
  • the fin-tube-type heat exchanger is made of a copper material, and the microchannel-type heat exchanger is made of an aluminum material.
  • the microchannel-type heat exchanger Since the microchannel-type heat exchanger is provided therein with fine flow passages, the microchannel-type heat exchanger has an advantage in that efficiency thereof is better than that of the fin-tube-type heat exchanger.
  • a small-sized microchannel-type heat exchanger which is used in a conventional refrigerator or the like, is manufactured in a one turn manner, there are problems in that only a simple refrigerant pass can be designed and in that heat exchange efficiency is decreased. Furthermore, since the small-sized microchannel-type heat exchanger, which is used in a refrigerator or the like, is constructed such that the numbers of refrigerant tubes disposed at an inlet and an outlet are equal to each other, the heat exchange capability is increased but efficiency of heat exchange is decreased in a zone in which a high-temperature refrigerant is introduced because the difference in temperature between the refrigerant and air is increased, whereas the heat exchange capability is decreased but efficiency of heat exchange is increased in a zone in which a low-temperature refrigerant is discharged because the difference in temperature between the refrigerant and air is decreased, thereby producing a problem whereby the overall efficiency of heat exchange is deteriorated.
  • a refrigerant tube of the conventional heat exchanger has the same cross-sectional area in the zone in which the refrigerant is introduced and in the zone in which the refrigerant is discharged, it is impossible to consider variation in the specific volume of the refrigerant, thereby causing a problem in which the amount of heat exchange is decreased.
  • a heat exchanger for a refrigerator according to the present invention is characterized in that a second heat exchange unit first exchanges heat with external air before a first heat exchange unit and in that the total cross-sectional area of the flat tubes of the first heat exchange unit is larger than the total cross-sectional area of the flat tubes of the second heat exchange unit.
  • the heat exchanger for a refrigerator is characterized in that, when an intermediate heat exchange unit is disposed between the first heat exchange unit and the second heat exchange unit, the total cross-sectional area of the flat tubes of the intermediate heat exchange unit is equal to or smaller than the total cross-sectional area of the flat tubes of the first heat exchange unit.
  • the heat exchanger for a refrigerator according to the present invention is characterized in that the inner diameter of the flat tubes of the first heat exchange unit is equal to the inner diameter of the second flat tubes and in that the number of flat tubes of the first heat exchange unit is larger than the number of flat tubes of the second heat exchange unit.
  • the heat exchanger for a refrigerator according to the present invention has one or more of the following effects.
  • the second heat exchange unit first exchanges heat with external air before the first heat exchange unit and since the total cross-sectional area of the flat tubes of the first heat exchange unit is larger than the total cross-sectional area of the flat tubes of the second heat exchange unit, there is an advantage in that it is possible to realize the optimal amount and efficiency of heat exchange relative to the specific volume of the refrigerant.
  • spatially relative terms such as “below”, “beneath”, “lower”, “above”, or “upper” may be used herein to describe one element's relationship to another element as illustrated in the figures. It will be understood that such spatially relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the figures. For example, if the device in one of the figures is inverted, elements described as “below” or “beneath” other elements would then be oriented “above” the other elements. The exemplary terms “below” or “beneath” can, therefore, encompass the positional relationships of both above and below. Since the device may be oriented in another direction, the spatially-relative terms may be interpreted in accordance with the orientation of the device.
  • each layer is exaggerated, omitted, or schematically illustrated for convenience of description and clarity. Also, the size or area of each constituent element may not accurately reflect the actual size thereof.

  • the refrigerant which has been compressed in the compressor 10, may exchange heat with the outdoor air and may thus be condensed while passing through the outdoor heat exchanger 20.
  • the outdoor heat exchanger 20 may be used as a condenser.
  • the refrigerant which has been condensed in the outdoor heat exchanger, may flow to the expander 12 and may then be expanded therein.
  • the refrigerant, which is expanded in the expander 12 may exchange heat with the indoor air and may thus evaporated while passing through the indoor heat exchanger 13.
  • the indoor heat exchanger 12 may be used as an evaporator for evaporating the refrigerant.
  • the refrigerant which has been evaporated in the heat exchanger 12, may be recovered to the compressor 10.
  • the refrigerant is circulated through the compressor 10, the outdoor heat exchanger 20, the expander 12 and the indoor heat exchanger 13 in a cooling cycle.
