Description

Cooling fin insert for chiller {APPARATUS FOR INSERTING COOLING FIN FOR COOLING DEVICE}

The present invention relates to a cooling fin inserting apparatus for a cooler, and more particularly, to a cooling fin inserting apparatus for a cooler configured to insert a cooling fin into a jig quickly and accurately.

Generally, a refrigerator is used to store food, and the like is repeatedly stored in a refrigerator to compress, condense, expand, and evaporate the refrigerant, thereby cooling the internal space to a predetermined temperature and preserving the food at a fresh temperature. I can do it.

The refrigeration cycle is provided with a refrigerant pipe through which the refrigerant gas flows, and a cooling fin, which serves as a heat exchanger, is fitted at predetermined intervals so that the contact area with air is widened on the outer circumferential surface of the refrigerant pipe. Is done.

The cooling fin is manufactured in a plate shape of a thin film using an aluminum alloy having high thermal conductivity, and is manufactured in a structure in which one or a plurality of through holes are drilled to fit the refrigerant pipe.

The cooling fins are assembled into the cooling pipes at predetermined intervals. To assemble the cooling fins in the refrigerant pipe, first, a plurality of cooling fins are mounted on a track having a guide, and then the tracks are moved along the jig. The cooling fins are inserted into the cooling fin insertion grooves formed by the own weight.

The cooling fin insertion grooves are formed at predetermined intervals along the jig so as to maintain a gap in one jig and to insert a plurality of cooling fins.

When the cooling fins are inserted into the insertion groove of the jig at regular intervals, the refrigerant pipe is inserted along the through-holes of the cooling fins.

Then, this is transferred to the banding device to bend the refrigerant pipe and pressurize the inside of the refrigerant pipe so that the outer diameter of the refrigerant pipe is slightly expanded so that the refrigerant pipe is completely in surface contact with the through hole of the cooling fin.

However, such a conventional cooling fin assembling device is a structure in which the cooling fin is inserted into the insertion groove of the jig by the weight of the cooling fin when the track moves along the insertion groove of the jig. There are many problems, and the assembly speed is very slow.

That is, since the cooling fin is made of a thin plate, the weight is very light, so it is often not inserted into the insertion groove by its own weight. In this case, the operator must manually insert the cooling fin.

When the insertion of the cooling fin is poor, the working speed is inevitably slowed down, and in order to reduce the insertion failure rate, slowing the feed rate of the track improves the defect rate but inevitably slows down the assembly speed.

In addition, the conventional inserting device has a disadvantage in that a separate operation is required for this purpose because the operator inserts the through-hole of the cooling fin into the guide part installed in the track.
