본 발명을 냉매관에 접합되는 리턴밴드의 접합이 신속하게 용이하게 실시할 수 있도록 한 것으로, 냉매관(11)이 독립된 관체로 이루어진 냉동기기(10)에 있어서 상기 독립된 냉매관(11)이 상호 연통되게 "U"자로 절곡된 리턴밴드(12)를 끼워 결합하고, 상기 냉동기기(10)의 리턴밴드(12) 결합부를 아연이 용융되어 있는 아연욕(21)에 일정 시간 침욕시켜 용융아연(24)이 냉매관(11)과 리턴밴드(12) 사이로유입되게 하며, 일정 시간이 경과하면 아연욕(21)에 침욕된 냉동기기(10)를 꺼내어 냉각시킨 후 리턴밴드(12)에 맺힌 맺힘돌기를 제거하므로 리턴밴드(12)의 접합이 완료되는 것이다.In the present invention, the return band to be joined to the refrigerant pipe can be quickly and easily carried out. In the refrigerator 10 having the refrigerant pipe 11 as an independent tube, the independent refrigerant pipes 11 are mutually connected. The return band 12 bent in communication with the letter "U" is inserted and combined, and the return band 12 coupling part of the refrigerator 10 is bathed in a zinc bath 21 in which zinc is molten for a predetermined time. 24 is introduced between the refrigerant pipe (11) and the return band (12), and after a certain period of time takes out the refrigeration unit (10) bathed in the zinc bath (21) and cools the condensation formed on the return band (12) Since the protrusions are removed, the joining of the return band 12 is completed.

여기서, 다수의 냉매관(11)이 상호 연통되게 결합되는 리턴밴드(12)에 용융아연(24)의 원활한 침투와 공기의 배출을 위한 다수의 유도홈(12a)을 형성하여 실시할 수 있므며, 상기 아연욕(21)의 용융아연(24)이 냉매관(11)과 리턴밴드(12) 사이로 원활하게 유입되게 초음파 진동기(22)에 초음파 진동되게하여 실시할 수 있는 것이다.Here, the plurality of induction grooves 12a for smooth penetration of the molten zinc 24 and discharge of air may be formed in the return band 12 in which the plurality of refrigerant pipes 11 are connected to each other. In addition, the molten zinc 24 of the zinc bath 21 may be ultrasonically vibrated to the ultrasonic vibrator 22 so as to smoothly flow between the refrigerant pipe 11 and the return band 12.

이하, 본 발명에 의한 접합장치에 대하여 설명하면 다음과 같다.Hereinafter, the bonding apparatus according to the present invention will be described.

본 발명의 접합장치는 내화재의 용기로 이루어진 아연욕(21)과, 상기 아연욕(21)을 가열하는 가열장치(23)와, 상기 아연욕(21)의 내부에 구비되어 용융아연(24)을 초음파 진동시킨는 초음파 진동기(22)로 구성한 것이다.The bonding apparatus of the present invention is provided with a zinc bath 21 made of a container of a fireproof material, a heating device 23 for heating the zinc bath 21, and a molten zinc 24 provided in the zinc bath 21. Ultrasonic vibrating is composed of an ultrasonic vibrator (22).

이하, 본 발명에 따른 냉동기기의 리턴밴드 접합과정을 설명하면 다음과 같다.Hereinafter, the return band bonding process of the refrigerator according to the present invention will be described.

상기한 바와 같이 아연침욕에 의하여 리턴밴드(12)의 접합이 이루어지는 본 발명은 전 공정을 통하여 다수의 냉매관(11)에 냉각핀을 끼워 결합한다.As described above, the present invention in which the return band 12 is bonded by the zinc bath is coupled to the plurality of refrigerant pipes 11 through the entire process.

그리고, 관체를 "U"자형으로 절곡 가공한 리턴밴드(12)의 양측 절곡 단부에 아연침욕과정의 원활한 용융아연(24)의 침투와 냉매관의 가스배출을 위한 유도홈(12a)을 가공형성한다.In addition, induction grooves 12a for smooth penetration of molten zinc 24 in the zinc bathing process and gas discharge of the refrigerant pipe are formed at both bent ends of the return band 12 in which the tubular body is bent into a “U” shape. do.

이상과 같이 냉매관(11)과 리턴밴드(12)의 제조가 완료된 상태에서 상기 리턴밴드(12)를 냉매관(11)에 끼워 결합한 후 아연이 용융되어 있는 아연욕(21)에 상기 냉동기기(10)의 리턴밴드(12) 결합부측을 침욕시킨다. 이때, 상기 아연욕(21)은 초음파 진동기(22)에 의하여 초음파 진동되는 상태이다.As described above, after the manufacture of the refrigerant pipe 11 and the return band 12 is completed, the return band 12 is fitted into the refrigerant pipe 11 to be combined, and then in the zinc bath 21 in which zinc is melted, the refrigerating device. The return band 12 engaging portion (10) is bathed. At this time, the zinc bath 21 is in a state of ultrasonic vibration by the ultrasonic vibrator 22.

상기한 바와 같이 초음파 진동되는 아연욕(21)에 냉동기기(10)의 리턴밴드(12) 결합부측을 일정 시간 침욕시키게 되면 냉매관(11)과 리턴밴드(12) 사이로 용융아연(24)이 고루게 침투되게 된다.As described above, when the return band 12 coupling part side of the refrigerating device 10 is bathed in the zinc bath 21 that is ultrasonically vibrated for a predetermined time, the molten zinc 24 is interposed between the refrigerant pipe 11 and the return band 12. Infiltrate evenly.

상기한 바와 같이 아연욕(21)에 침욕된 냉동기기(10)를 건져낸 후 냉각시키게 되면 리턴밴드(12)에 아연이 맺혀 맺힘돌기가 형성되는데 이상과 같이 형성된 맺힘돌기는 연삭기로 연삭 제거하므로서 리턴밴드(12)의 접합이 완료되는 것이다.As described above, when the freezing device 10 bathed in the zinc bath 21 is cooled and then cooled, zinc is formed in the return band 12 to form a binding protrusion. The binding protrusion formed as described above is returned by grinding and removing with a grinding machine. Bonding of the band 12 is complete.

따라서, 본 발명은 불활성 가스 용접등과 같은 방법을 통하여 냉매관과 리턴밴드를 접합하는 것이 아니라 초음파 진동되는 아연용융액에 침욕시켜 접합을 실시하므로서 그 작업이 신속하게 이루어지며 아연용융액이 초음파 진동에 의하여 냉매관과 리턴밴드 사이로 고루게 충진되므로 그 접합이 견고하게 이루어지는 매우 유용한 것이다.Therefore, the present invention is not performed by joining the refrigerant pipe and the return band by a method such as inert gas welding, but rather by bathing in the ultrasonically vibrated zinc melt, the operation is performed quickly, and the zinc melt is ultrasonically vibrated by ultrasonic vibration. Since it is evenly filled between the refrigerant pipe and the return band, the junction is very useful.
