Abstract

The present invention relates to a heat exchanger for an ice maker, in which a recessed groove of a ring shape is formed on an outer surface of an ice-making unit, a ring member having a through-hole formed in the recessed groove is welded to cover the recessed groove, and the through-hole of the ring member is connected to a refrigerant flow pipe to allow refrigerant to pass through the recessed groove covered by the ring member, so that the cold air is gathered in the recessed portion of the ice-making unit by the refrigerant passing through the recessed groove. In this case, the fluid passing from an upper side to a lower side of the ice-making unit is rapidly cooled while passing through an inner circumferential surface corresponding to the recessed groove, thereby making ice. According to the present invention, since the refrigerant continuously flows into the recessed groove of the ice-making unit through the refrigerant flow pipe, the plurality of ice-making units may be cooled rapidly, and cold air may remain in a depressed portion of the recessed groove stepped at a specified portion of the ice-making unit, so that it is possible to prevent the cold air from remaining and being dispersed in the entire area of the ice-making unit. In addition, the cooling air is concentrated at a specific portion of the ice making unit due to the prevention of the dispersion of the cold air, so that the cooling efficiency is raised. Accordingly, the fluid passing through the ice-making unit instantaneously freezes at the time of passing through an inner peripheral surface corresponding to the recessed groove, so that the reliability of the product is improved.

Description

제빙장치용 열교환기{Ice maker for heat exchanger}[0001] The present invention relates to an ice maker for a heat exchanger,

본 발명은 열교환기에 관한 것으로서, 더욱 상세하게는 제빙유닛의 함몰홈 부분으로 냉매를 경유시켜, 제빙유닛의 함몰홈 부분을 냉각시키는 제빙장치용 열교환기에 관한 것이다.The present invention relates to a heat exchanger, and more particularly, to a heat exchanger for an ice maker for cooling a recessed groove portion of a freezing unit by passing a coolant through a recessed groove portion of a freezing unit.

일반적으로, 제빙장치는 흐르는 공급수나 혹은 정해진 공간내에 저장된 공급수를 얼려 얼음을 만들어 내는 장치이다.Generally, the ice maker is a device for producing ice by freezing the supplied water or the supply water stored in a predetermined space.

여기서, 제빙장치는 그 내부에 열교환기를 구비하고, 이 열교환기는 반복 순환되는 냉매에 의해 저온상태를 유지하며, 이 저온상태의 열교환기로 공급수가 흘러가도록 함으로써, 공급수가 열교환기와의 열교환작용으로 냉각되어 얼음으로 형성된다.Here, the ice maker has a heat exchanger therein. The heat exchanger is maintained at a low temperature state by the refrigerant repeatedly circulated, and the supply water flows to the heat exchanger in the low temperature state, so that the supply water is cooled by heat exchange action with the heat exchanger It is formed of ice.

특허문헌 1은 종래의 제빙장치를 나타낸 것으로서, 이를 참조하면, 일렬 배치되어 공급수가 상방에서 하방으로 흐르도록 안내하는 복수의 제빙유닛과, 복수의 상기 제빙유닛 각각의 외주면에 길이방향을 따라 1열 이상으로 설치되어 상기 제빙유닛을 통해 상방에서 하방으로 흐르는 공급수를 냉각시키는 열교환부로 구성된다.Patent Document 1 discloses a conventional ice maker. Referring to this, a plurality of ice-making units arranged in a line and guiding the supply water to flow downward from above, and a plurality of ice- And a heat exchanger installed above the ice making unit to cool the supply water flowing from the upper side to the lower side through the ice making unit.

여기서, 상기 열교환부의 외면에는 수평선을 기준으로 서로 어긋나도록 형성된 냉매유입관 및 냉매배출관이 형성된다.Here, a refrigerant inlet pipe and a refrigerant outlet pipe are formed on the outer surface of the heat exchanger so as to be offset from each other with respect to a horizontal line.

이때, 상기 냉매유입관을 통해 공급된 냉매는 상기 열교환부의 냉매자유관로부를 경유한 후, 상기 냉매배출관을 통해 토출되고, 토출된 냉매는 또 다른 상기 열교환부를 순차 반복적으로 경유하여 말단에 형성된 상기 열교환부의 냉매배출관을 통해 토출된다.At this time, the refrigerant supplied through the refrigerant inflow pipe passes through the refrigerant free duct portion of the heat exchanging portion, and is discharged through the refrigerant discharge pipe. The discharged refrigerant passes through the other heat exchanging portion sequentially and repeatedly, And is discharged through a negative refrigerant discharge pipe.

그러면, 상기 열교환부를 경유하는 냉매에 의해 상기 제빙유닛의 외주면이 냉각 상태로 유지되고, 이때, 상기 제빙유닛의 내주면을 타고 하방으로 흐르는 공급수가 냉각 상태의 제빙유닛 부분을 통과하면서 열교환작용에 의해 제빙된다.Then, the outer circumferential surface of the ice-making unit is maintained in a cooled state by the refrigerant passing through the heat exchanging unit. At this time, the supply water flowing downward on the inner circumferential surface of the ice-making unit passes through the ice- do.

하지만, 상기와 같은 특허문헌 1은 제빙유닛의 외면이 평평하게 형성 제빙유닛의 냉각부분을 기준으로 냉기가 상, 하로 고르게 분산되고, 이 냉기의 분산으로 열교환부가 설치된 제빙유닛의 외주면에 냉기가 집중되지 못하며, 이때, 냉기가 분산된 제빙유닛으로 유체가 그대로 통과되어, 유체가 차가워 질뿐 얼음으로 제빙 되지 않으며, 이에따라, 냉매 공급량에 비해 제빙유닛의 특정부분의 냉각 효율이 저하되어, 제품의 신뢰성이 저하되는 문제점이 있다.However, in the above-described Patent Document 1, the outer surface of the ice-making unit is formed flat. The cold air is evenly distributed over the cooling portion of the ice-making unit, and cold air is concentrated on the outer peripheral surface of the ice- At this time, the fluid is directly passed through the ice making unit in which the cold air is dispersed, and the fluid is cooled, and the ice is not iced. As a result, the cooling efficiency of a specific part of the ice making unit is lowered compared to the refrigerant supply amount, There is a problem of deterioration.
