Description

Heat exchanger for air cooling

The present invention relates to an air-cooled heat exchanger, and more particularly, by installing a blower fan on the bottom of the inside formed in a quadrangular box shape to form an external air to raise the air flow from the bottom to the upper side, the efficiency and structural characteristics of the heat exchange In addition, heat exchanger pipes installed inside are formed integrally by extrusion molding on the inner and outer surfaces, but are formed radially to improve manufacturability and blower air flow of the blower fan along the lengthwise direction of the heat exchanger pipe. To an air-cooled heat exchanger to improve heat exchange performance.

In general, a heat exchanger is a device for obtaining a medium having a required temperature by contacting a medium having a different temperature, that is, a liquid such as water or oil, or a gas such as air or gas, so that mutual heat exchange is performed. .

This heat exchanger is not only applied to boilers or hot water heaters of general households, but also to various air-conditioning and heating devices, and is widely used in various fields including various industrial fields. It is proposed and used.

For example, it may be divided into a water-cooled heat exchanger for heat exchange using a liquid medium such as water or oil, and an air-cooled heat exchanger for heat exchange using a gaseous medium such as air or gas. An air-cooled heat exchanger for cooling compressed air in a compressor or a refrigerator of a refrigeration tower vehicle.

Looking at an example of the alternative configuration of the heat exchanger that is most widely used among the air-cooled heat exchanger as described above, as shown in Figures 1 to 5 of the accompanying drawings.

The heat exchanger (1) has a heat exchange pipe (3) in which a gaseous medium such as compressed air or gas passes through is arranged in a zigzag manner in a frame (2) made of a substantially rectangular shape, and the heat exchange pipe (3) In the outer surface of the heat exchanger and a plurality of heat transfer fins (4) to increase the heat exchange efficiency are installed at regular intervals, and on one side of the frame (2) by blowing air to force the heat exchange is forced The fan 5 is configured to be driven by the motor 6.

Therefore, the compressed air is circulated through the heat exchange pipe 3 by the system of the air conditioner (not shown), and the external air is blown from one side of the heat exchanger 1 to the other side by the forced blowing of the blower fan 5. Compressed air is heat-exchanged by the frictional force of the surface of the heat exchange pipe (3) and the plurality of heat transfer fins (4) formed on the surface of the heat exchange pipe (3) to be cooled.

However, such a configuration of the general heat exchanger 1 has various problems.

First, most of the heat exchangers of the prior art are configured to install the heat transfer fins 4 made of aluminum having excellent thermal conductivity on the surface of the heat exchange pipe 3 made of copper. This was a bad problem.

That is, the conventional connection work method is to insert and fasten the heat transfer fin (4) made of a hard aluminum material with good thermal conductivity to the heat exchange pipe (3) made of a relatively soft copper material as shown in Figure 4 of the accompanying drawings Next, the external diameter of the heat exchange pipe 3 is expanded by a separate device so as to be fixed by forcible adhesion.

In this case, there is a problem in that the heat conduction efficiency is significantly lowered due to an air layer in which fine foreign matters such as dust are trapped between the inner diameter of the heat transfer fin 4 and the outer diameter of the heat exchange pipe 3, or which is not in close contact.

In addition, due to the different materials of the heat exchanger pipe and the heat transfer fins, other joining operations such as welding are difficult, and thus, multi-stage expansion work must be performed. There was a problem that the manufacturing cost of the product is increased, such as the use of (4).

In particular, the heat exchanger (1) using the heat exchange pipe as described above is not blown to the four corners (A) of the heat exchanger (1) made of a square during forced heat exchange by the blowing force of the blowing fan (5) The phenomenon that the heat exchange efficiency is lowered as much as that occurs, and also in the rear of each heat exchange pipe (3), as shown in Figure 5 of the accompanying drawings, the dead zone (B) where the blowing force is not generated, the heat exchange efficiency is reduced by that much There was a problem.

The present invention has been made in view of the above-described various problems, and its object is to simplify the overall configuration of the heat exchanger, and at the same time, the heat conduction pipe and heat conduction fins, which are essentially used for the heat exchanger, are formed in a radial unitary form, while being thermally conductive. It is to provide an air-cooled heat exchanger that can be extruded by this excellent aluminum material, and greatly reduce the manufacturing cost with the convenience of manufacturing.

Another object of the present invention is to facilitate the flow of the air flow by making the heat exchange air flow in the longitudinal direction of the heat exchange pipes installed vertically inside the heat exchanger, and at the same time, the heat of the heated air between the heat transfer fins quickly and easily To provide an air-cooled heat exchanger to move to improve the heat exchange efficiency.

The present invention for achieving the above object is achieved by providing a heat exchanger of a new concept in which the configuration of the air-cooled heat exchanger integrally improved, the heat exchanger is configured to have a body of a rectangular box as a whole, and at the same time The heat exchange fins are integrally arranged to vertically arrange a plurality of heat exchanger pipes, and a blower fan is installed horizontally on the inner upper surface of the heat exchanger so that the blower air flows up from the bottom to the top. At the same time, it is characterized in that the upper and lower intake grill and exhaust grill to form.

In another aspect, the present invention is characterized in that the heat exchanger pipe used in the heat exchanger is formed of an aluminum material having excellent thermal conductivity, while the inner and outer surfaces thereof are integrally formed by extrusion molding of heat transfer fins formed radially along the longitudinal direction. will be.

The present invention has the advantage of greatly reducing the manufacturing cost because the overall configuration of the air-cooled heat exchanger is simple to improve the workability according to manufacturing and assembly, and can be applied to various fields as the overall volume and size can be formed small. In addition to this possible advantage, handing due to transportation and storage has a good effect.

In addition, the present invention can not only integrally extrude the heat exchange pipe and the heat transfer fins, but also have excellent thermal conductivity and can be formed of a relatively inexpensive aluminum material, thereby significantly improving the manufacturing cost as well as the manufacturability. In addition, the efficiency due to heat exchange will also have the effect of significantly improved.

In addition, the present invention is installed in the heat exchange pipe vertically and at the same time the blower fan is installed in the upper portion of the heat exchanger to induce suction so that the blowing air according to the rising air flow from the bottom to the upper side is transferred between each heat transfer fin At the same time to move the heated air more quickly and smoothly, the heat exchange is made smoothly has the effect of significantly improving the heat exchange efficiency.

In particular, the present invention is provided with a separate expansion means to achieve a throttling action at the inlet side of the heat exchange pipe, the cooling effect is primarily made by the instant throttling action when the circulated medium is introduced into the heat exchange pipe, thereby doubling the heat exchange efficiency. To have.

Hereinafter, with reference to the accompanying drawings, the specific content for the preferred embodiment of the present invention will be described in detail.

6 to 9 of the accompanying drawings shows the structure of the overall air-cooled heat exchanger according to the present invention, Figure 10 or less shows the detailed structure and other embodiments of the present invention, the reference numeral 100 of the figure of the present invention heat exchanger The main body of the flag is shown.

The air-cooled heat exchanger 100 is a device mainly used to cool compressed air or a high temperature air, such as a compressor, and is generally composed of a body 110 having a rectangular enclosure type, and having a support leg 111 at the bottom thereof. Is formed and used as a single component in various equipment,

The present invention air-cooled heat exchanger 100 is installed in a plurality of heat exchange pipes 120 are arranged vertically while zigzag connected in the interior of the body 110, one side is connected to a separate air conditioner not shown in the high temperature At the same time having the inlet 121 through which air is introduced, the other side is heat-exchanged and the outlet 122 through which the cooled air is discharged is connected and circulated.

The heat exchange pipe 120 is made of an aluminum material as shown in more detail in Figures 10 and 11 of the accompanying drawings, and a plurality of heat transfer fins 123 are formed integrally with the inner and outer radially extruded.

That is, the heat exchange pipe 120 is formed of a hard aluminum material having a light weight and excellent thermal conductivity and a relatively low price, and the heat transfer fins 123 made of the same aluminum material on the inner and outer surfaces thereof are radially extruded. It has a structure.

The heat transfer fins 123 are formed in a thin plate body and are integrally formed to extend not only to the outer surface of the heat exchange pipe 120 but also to the inner surface, so that the heat medium passing through the outside air and the inside of the heat exchange pipe 120 is smooth through them. It is possible to exchange heat actively.

At this time, the heat transfer fin 123 may be formed in various arbitrary forms such as the number, length, thickness, etc. in consideration of the shape or performance of the applied product, as shown in FIG. 12 of the accompanying drawings as another embodiment. The heat transfer fins 123a may be formed only on the outer surface of the heat exchange pipe 120a.

In this case, when the diameter of the heat exchange pipe 120a is very small or when the heat medium uses a viscous liquid rather than a gas, the flow of the heat exchange medium can be smoothed.

In addition, the heat transfer fins 123 may be formed in a thin plate shape, or a plurality of protrusions 124 or grooves 125 may be formed as shown in FIGS. 13A and 13B for strength reinforcement while expanding the surface area thereof. will be.

In addition, as shown in FIGS. 14 and 15 of the accompanying drawings, the inlet side of the heat exchange pipe 120 vertically installed as described above has a function of primarily cooling the heat exchange medium circulated by installing a separate expansion means 140. Will be provided.

The expansion means 140 forms a conical derivative 141 inside the heat exchange pipe 120, and fine passage holes 142 are formed on the outer circumference thereof to allow the medium to pass along the circumferential direction. .

As the derivative 141 is formed in a conical shape, the heat medium is instantaneously dispersed and a whirlwind occurs at the same time, and the through hole 142 is intended to induce a sudden pressure difference as it passes.

In addition, a blower fan 130 driven by a motor 131 is installed on an inner upper surface of the body 110, and inlet grills in which external air flows into the upper and lower portions of the body 110 by the blower fan 130 are provided. 132 and the discharge grill 133 is formed respectively.

The blowing fan 130 is formed side by side on both sides of the motor 131 is configured to blow the blown wind from the bottom to the top, that is, natural rise along the heat exchange pipe 120 is installed vertically The airflow is formed to provide a function of improving the blowing force.

In addition, the inlet grill 132 is installed at a lower position so that the outside air can be smoothly introduced into the interior of the body 110 by the blowing fan 130, the discharge grill 133 is the upper portion of the body 110 Installed in the air flow is configured to smoothly discharge the rise to the outside.

At this time, the inlet grill 132 and the discharge grill 133 may be formed in various forms, such as a hole or grille as usual, and of course, even if the installation position is slightly different, the same effect can be expected. Could be.

On the other hand, the air blowing means as another embodiment, as shown in Figure 16 of the accompanying drawings, the blower fan 130 and the motor 131 can be formed in the inner bottom to blow from the bottom to the top, of course, The inlet grill 132 may be formed in the form of a hole in the side.

In addition, in order to improve the heat exchange performance according to the blowing as shown in Figure 17 of the accompanying drawings by forming a separate guide plate 150 on the path through which the outside air flows into the body 110, the inlet grill 132 It is possible to improve the heat exchange performance by allowing the external air introduced through it to be concentrated only blown through the heat exchange pipe (120).

In particular, the heat exchanger 100 according to the present invention, as well as the overall size, as well as the overall length, number of heat exchange pipes 120 installed therein may be different or the arrangement will be natural. .

On the other hand, another embodiment of the present invention is shown in detail in Figures 18 to 21 of the accompanying drawings, which is different from the structure of the heat exchange pipe described above, that is, on the inner surface and the outer surface of the heat exchange pipe (120b) The heating fins 123b formed radially are formed in a spiral shape.

In this case, since the heat transfer fins 123b are formed radially on the inner and outer surfaces of the heat exchange pipe 120b, the heat medium passing through them is not only maximized by the plurality of heat transfer fins 123b, but also to the outside. The blown wind will also generate a whirlwind along with an increase in the heat exchange area due to the spiral heat transfer fins 123b, thereby maximizing heat exchange.

Therefore, the heat exchanger 100 of the present invention configured as described above is mainly used to cool high-temperature air compressed in a device such as a compressor or a refrigerator of a refrigeration tower vehicle, and as a whole is made in a compact rectangular enclosure shape. It is easy to apply and easy to manufacture.

In the present invention, both sides of the inlet 121 and the outlet 122 of the body 110 are connected to a conventional heat exchange system, which is not shown in the drawing, so that a high-temperature heat exchange medium mainly formed in a gaseous state is introduced into the inlet 121 to exchange heat. After cooling while passing through the pipes 120, the discharged through the outlet 122 is circulated.

At this time, the temperature of the heat exchange medium is primarily lowered by the throttling action by the expansion means 140 formed on the inlet side of the heat exchange pipe 120.

That is, the moment when the heat exchange medium circulated along the pipe is blocked by the conical derivative 141 and passes through the through holes 142 bored along the circumferential direction, the medium is rapidly discharged to a wide place through a narrow place and is pressured. This rapidly lowers the throttling effect of lowering the temperature.

In addition, the blowing fan 130 is driven to rotate by the power of the motor 131 formed on the bottom of the body 110, the outside air flows into the both side inlet grill 132 of the bottom of the body 110 After cooling the medium circulated therein while passing through each heat exchange pipe 120 installed vertically, it is discharged to the outside through the discharge grill 133 on the upper portion of the body 110.

That is, the wind blown by the blower fan 130 makes rapid heat exchange with the surface of the heat exchange pipe 120 and the heat transfer fins 123 integrally formed on the surface thereof, thereby sufficiently cooling the medium circulated therein. do.

At this time, the heat exchange pipes 120 are vertically formed along the direction of the wind to be blown, and at the same time the heat transfer fins 123 formed on the surface thereof are radially formed so that the flow of the air flows more smoothly. The heat transferred to 123 is to be cooled evenly.
