간냉식 냉장고의 증발기구조Evaporator Structure of Intercooling Refrigerator

본 발명은 냉장고의 증발기에 관한 것으로 보다 상세하게는 증발기의 운반 및 조립시 부품변형의 문제점을 개선하고 제조단가를 낮추며 제상열의 효율적인 이용으로 제상시간을 단축시킬 수 있도록한 간냉식 냉장고의 증발기구조에 관한 것이다.The present invention relates to an evaporator of a refrigerator. More particularly, the present invention relates to an evaporator structure of an intercooled refrigerator that improves the problem of component deformation during transport and assembly of an evaporator, lowers manufacturing costs, and shortens defrost time by efficient use of defrost heat. It is about.

일반적으로 냉장고의 증발기는 저온저압의 습포화증기(다량의 냉매액과 미량의 냉매가스로 이루어진 상태)로 된 냉매가 냉동싸이클에 의해 냉매 파이프를 관류하며 외부공기의 열을 흡수함으로써 외부공기는 냉각되게하여 냉기를 생성시키고 냉매자신은 저온저압의 건포화증기(다량의 냉매가스와 미량의 냉매액으로 이루어진 상태)로 되어 배출되는 장치인데 주로 사용되고 있는 일반적인 냉장고는 간냉식 냉장고가 대부분이다.In general, the evaporator of the refrigerator cools the external air by absorbing heat from the refrigerant pipe through the refrigerant pipe through the refrigerant cycle, which consists of a low-temperature, low-pressure wet vapor (a state consisting of a large amount of refrigerant liquid and a small amount of refrigerant gas). The coolant itself is a device that is discharged by the low temperature low pressure dry saturated steam (a state consisting of a large amount of refrigerant gas and a small amount of refrigerant liquid), the most commonly used refrigerator is the intercooled refrigerator.

도1은 종래 간냉식 냉장고의 증발기 구조를 나타낸 사시도로서, 도1에 도시된 바와 같이, 양측판의 후측 상단에는 볼트삽입공(65)이 천공된 고정부(60)가 각각 형성되고 상기 양측판(80)의 내측으로는 냉매파이프(10')가 수회 절곡되어 지그재그 형상으로 설치되며 상기 냉매파이프(10')의 외주면에 사각편상으로된 다수개의 냉각핀(25')을 설치하여 증발기(100')와 냉기의 접촉면을 넓힘으로써 냉동효과가 향상되도록한 구성을 하고 있다.1 is a perspective view showing an evaporator structure of a conventional intercooled refrigerator. As shown in FIG. 1, fixing parts 60 having bolt insertion holes 65 are formed at rear upper ends of both side plates, respectively, and both side plates ( Inside the 80, the refrigerant pipe 10 'is bent several times to be installed in a zigzag shape, and an evaporator 100' is installed by installing a plurality of cooling fins 25 'in a rectangular piece on the outer circumferential surface of the refrigerant pipe 10'. ), The freezing effect is improved by widening the contact surface of the cold air.

그런데 종래의 증발기(100')의 냉각핀(25')은 단순히 냉각핀(25')의 중앙에 냉매파이프(10)의 외경과 대응되는 끼움공(미도시)이 형성된 얇은 사각편상으로 형성되었으므로 증발기(100')의 내부와 외부공기의 온도편차에 의하여 발생되는 성에가 상기 냉각핀(25')의 표면에 착상되어져 증발기(100')의 냉동효과를 저감시키는 폐단이 있었으며 냉각핀(25')의 두께가 매우 얇아서 운반이나 조립시에 변형되는 경우가 많았다.However, since the cooling fin 25 ′ of the conventional evaporator 100 ′ is simply formed in a thin rectangular piece having a fitting hole (not shown) corresponding to the outer diameter of the refrigerant pipe 10 in the center of the cooling fin 25 ′. The frost generated by the temperature difference between the inside and the outside air of the evaporator 100 'is deposited on the surface of the cooling fin 25', thereby reducing the freezing effect of the evaporator 100 '. ) Was so thin that it was often deformed during transport and assembly.

또한 이러한 성에의 제상시에는 증발기(100') 하단 중앙의 히터고정부(50') 내측에 설치된 제상히터(55')에서 발생되는 열기가 냉각핀(25')을 지지하는 냉매파이프(10')를 경계로 상기 냉각핀(25')의 상측에서 와류현상을 일으켜 증발기(100')의 상부로는 열전달이 제대로 이루어지지 않아 증발기(100')의 제상효율이 저하되고 증발기(100')의 제조원가도 비싼 문제점이 있어왔다.In addition, during defrosting of the frost, the heat generated from the defrost heater 55 'installed inside the heater fixing part 50' at the bottom center of the evaporator 100 'cools the pipe 10' to support the cooling fin 25 '. Vortex phenomenon occurs on the upper side of the cooling fin 25 'to prevent heat transfer to the upper portion of the evaporator 100', and thus defrosting efficiency of the evaporator 100 'is reduced and the evaporator 100' Manufacturing costs have also been an expensive problem.

상기와 같은 문제점을 해결하기 위하여, 본 발명 간냉식 냉장고의 증발기구조는 냉매유로가 형성되어 있는 롤본드타입 증발기의 전면부 및 후면부에 다수의 냉각핀을 형성하고 후면부 하단의 히터고정부에 제상히터를 설치하며 상단부에 다수의 냉기구를절결형성하여 부품변형의 문제점을 개선하고 증발기의 제조단가를 낮추며 제상열의 효율적인 이용으로 제상시간을 단축시켜 제상히터의 작동에 소비되는 소비전력 저감효과를 이룰 수 있도록한 증발기의 제공을 그 기술적과제로 한다.In order to solve the above problems, the evaporator structure of the intercooled refrigerator of the present invention forms a plurality of cooling fins on the front and rear portions of the roll bond type evaporator in which the refrigerant flow path is formed, and a defrost heater is formed on the heater fixing part at the bottom of the rear portion. It can be installed in the upper part of the air conditioner to improve the problem of component deformation, reduce the manufacturing cost of the evaporator, reduce the defrosting time by efficient use of the defrost heat, and reduce the power consumption of the defrost heater. The technical task is to provide an evaporator.

한편 도2에는 어큐뮬레이터(30)가 별도로 설치되어 있으나 증발기(100)의 냉매파이프(10)상에 어큐뮬레이터(30)의 형상을 설계하도록 별도의 어큐뮬레이터(30)를 별도로 설치하지 않음으로써 부품감소로 인한 비용절감효과도 기대할 수 있다.Meanwhile, although the accumulator 30 is separately installed in FIG. 2, the accumulator 30 is not separately installed to design the shape of the accumulator 30 on the refrigerant pipe 10 of the evaporator 100. Cost savings can also be expected.

이와 같은 구성으로 이루어진 본 발명은 냉동싸이클에 의해 유동되어 저온저압의 습포화증기로된 냉매가 지그재그 형상으로 다수회 절곡된 상기 증발기(100)의 냉매파이프(10)의 내측으로 유입되어 외부공기의 열을 흡수함으로써 냉기를 생성시키게 되면 송풍팬(90)의 급속회전에 의해 냉기를 냉동실(1) 및 냉장실(2)로 공급하게 되며 냉동실(1) 및 냉장실 (2)로 공급된 냉기는 귀환덕트(95)를 통해 증발기(100)로 귀환되어 냉각핀(25) 및 냉매파이프(10)가 설치된 증발기(100)를 통과하면서 열교환되어 재차 순환하게 되는 것이다.According to the present invention having such a configuration, the refrigerant flowed by the refrigeration cycle, and the refrigerant vaporized at low temperature and low pressure, is introduced into the refrigerant pipe 10 of the evaporator 100 which is bent in a zig-zag shape many times, and thus the external air is discharged.
