Description

Fin Tube, Fin Coil Condenser and Manufacturing Method {FIN TUBE, FIN COIL CONDENSER AND A METHOD THEREOF}

The present invention relates to a condenser, a cooling fin tube, and a radiator for a refrigerator, and more particularly, to a fin tube, a fin coil, and a refrigerator condenser and a heat exchanger using the same pipe and a heat dissipation fin blade formed in parallel.

Refrigerator is used to freeze or refrigerate food and the like. The low-temperature, low-pressure gaseous refrigerant is compressed to high temperature and high pressure by a compressor, and the compressed high-temperature and high-pressure gaseous refrigerant is cooled and condensed while passing through the condenser. It is converted into a liquid phase, and the high-pressure liquid refrigerant passes through a capillary tube, and its temperature and pressure are lowered. Then, the refrigerant is changed into a low-temperature, low-pressure gas state in an evaporator, which takes heat from the surroundings and cools the air around it. .

Conventionally, the general condenser and evaporator applied to the refrigerator is a metal material ?? A thin panel that is continuously bent in the form of a plurality of layers, and a plurality of layers arranged in parallel at regular intervals and attached to the refrigerant tube by welding, and are mounted in a form that crosses the seemingly bent refrigerant tube. Fin tube type, which consists of heating fins of the type, is mainly used.In conventional fin type condensers, the pipes and fins are arranged laterally so that dust and dirt are caught between the fins and the pipes and the dust is not artificially removed. There are many failures, and the refrigeration capacity is lowered due to poor heat transfer cooling, and the welding work on the pipe connection is inevitably increased and difficult in manufacturing.

In addition, the conventional wire type condenser has a problem that it can take a large space between the wire and the wire is not dusted, but the heat transfer effect is not good occupy a large installation area.

In addition, the conventional fin tube has a small area of the fin plate in contact with the outer area of the pipe, and thus the heat transfer between the pipe and the fin is not smooth.

The technical problem to be achieved by the present invention is to provide a condenser having a structure that can increase the area in contact with the fin to the pipe to facilitate heat transfer and heat exchange efficiency while at the same time the production process is simple to reduce the manufacturing cost.

In another aspect, the present invention provides a pin tube and a pin coil that can be easily cleaned with dust or dirt between pins and pins.

The present invention wraps the pin blades made of copper foil, aluminum foil, and other good thermally conductive plates on the pipe, and draws them by drawing, crimping, and welding them on high frequency, leaving the wings on both sides of the fin to increase the heat transfer area. At this time, the copper plate and the aluminum plate may be bent and bent to form fins having bent parts, small pieces, and holes to widen the heat transfer cooling area of the fins. The fins are integrally compressed and banded by coaxial fin tubes, which are banded with circular coils or polygonal coils to make pin coils, and use them to manufacture refrigerated refrigerators or air conditioner refrigerant condensers.

It is also used as hot water boiler and heat pipe tube.

The present invention wraps the fin blades of copper foil, aluminum foil, and other good thermal conductivity plates on the coil pipe for the condenser of the refrigerator, draws, compresses, draws them, leaves the fin wings on both sides, and expands the heat transfer area. At this time, by bending the copper plate, aluminum plate by pressing, punching, etc. can be formed bent portion, small piece portion, holes. The plate is wound around the pipe at 180 to 360 degrees, joined, and high frequency welded to form a fin tube.

The fins are integrally pinned in parallel in a longitudinal straight line of the pipe to squeeze the pinned tube with a circular coil or polygonal coil to produce a refrigeration refrigerator or an air conditioner condenser.

It is also used as a hot water boiler, heat pipe tube, and heat exchanger tube for various heat exchangers.

In the present invention, a coaxial fin tube having one or more fins made of copper plate, aluminum plate or other good thermal conductivity plate coaxially with the pipe, drawn and crimped by drawing or crimping or welded to leave the fins wide and leaving a heat transfer area. Provides a method of manufacturing a condenser for a refrigeration refrigerator air conditioner to produce a pin coil by bending the coiled or polygonal.

The pipes and fins can be made of copper, aluminum, alloys, plastics or other materials with good thermal conductivity.

The present invention will be described in detail with reference to the drawings of the preferred embodiments.

1 to 2, the copper foil and aluminum plate fins 2 are wound on the pipe 1 and wound around the pipe at 180 to 360 degrees while compressing the blades on both sides with high-frequency welding.

8A and 8B, two pipes may be wound with a single plate pin to be crimped for high frequency welding.

At this time, the copper plate and the aluminum plate are pressed by pressing to give both wings of the fin 2 in the longitudinal or transverse direction as shown in FIG. 7A and 7B or to form a wing curved small piece 3 to increase the heat transfer area. have.

3, 4 and 5, the fin tube (4) produced as described above is bent to produce a fin coil (5) for the condenser. The fincoil condenser manufactured as described above as shown in FIG. 6 is heat-transduced by cooling and heat-transferring through the air flow by the operation of the ventilating pen 6.

Here, the pin is a copper plate, an aluminum plate, various alloy flakes, a metal foil or a plastic pin.

Also, as shown in FIGS. 9A, 9B, 10A, and 10B, the pipe and the fin may be integrally formed and extruded simultaneously.

In addition, the present invention may be modified such that the two fins are arranged to face each other on both sides of the pipe to face each other or to vary the shape to further widen the heat transfer area of the fin.

Conventional forced convection condenser is a cross-meshed fins and wires to increase the heat transfer area and the refrigerant flow, which leads to a lot of dust, which causes the heat transfer of the condensation condenser worse, resulting in poor refrigerator efficiency and burnout of the compressor. Will cause refrigerator failure, etc.

Fin tube condenser according to the present invention is a pipe in which the refrigerant flows and the fins for widening the heat transfer area is arranged in a straight line in parallel with the dust does not get well and the air flow is smooth and cleaning by the air flow of the fan proceeds to the dust at the same time There is no malfunction and there is no deterioration of freezing capacity due to poor condensation of refrigerant due to dust.

In addition, since the pipes and the pins are decorated in a straight line drawing and crimping method, the inlet and outlet of the refrigerant pipe can be manufactured by bending one pipe into a desired shape, thus reducing the manufacturing cost of the condenser. do.

The effect of preventing the compressor failure of the condenser can be expected.
