Description

Fin for heat exchanger

The present invention relates to a heat dissipation fin for a heat exchanger, and more particularly, to a heat exchanger fin configured to be capable of increasing heat dissipation performance and improving drainage.

In general, the heat exchanger is a device for lowering or raising the temperature of a fluid by releasing heat energy of the fluid to the outside, and is equipped with heat sink fins of various shapes to increase the heat radiation area.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the shape and mounting structure of the conventional heat sink fins.

1 is a perspective view showing a mounting structure of a conventional heat dissipation fin for a heat exchanger, Figure 2 is a vertical sectional view of a heat dissipation fin for a conventional heat exchanger.

1 is a partial perspective view of an evaporator for delivering cold air generated from a low temperature refrigerant to a vehicle interior, and is mounted between a plurality of tubes 10 arranged up and down spaced side by side, and between two neighboring tubes 10. It is configured to include a plurality of heat radiation fins 20.

The heat dissipation fins 20 are mounted to be in contact with the tube 10. The cool air of the refrigerant flowing in the tube 10 is transferred to the heat dissipation fins 20, and the air passing through the heat dissipation fins 20 is cooled coolly. Is passed into the room. Meanwhile, the heat dissipation fins 20 are formed in a continuous mountain shape having a predetermined pitch, that is, a zigzag shape in which the floor 22 and the valleys 24 are alternately provided, and the surface area of the heat dissipation fins 20 is increased to exchange heat. A plurality of louvers 26 are formed to make this more effective.

At this time, the method of forming the louver 26 in the planar portion between the floor 22 and the valleys 24 has a limitation in increasing the surface area of the heat dissipation fin 20, and thus significantly increases the surface area of the heat dissipation fin 20. In order to do this, the pitch must be made narrow. However, if the pitch is made too narrow, the coupling part between the heat dissipation fin 20 and the tube 10 increases, making manufacturing difficult, as well as the lower point of the floor 22 and the upper point of the valley 24 are very narrow. There is a problem that the flow of air is not smooth.

In addition, when the floor 22 and the valley 24 are formed to have a predetermined inclination angle, as in the conventional heat dissipation fin 20, the moisture generated on the surface is not smoothly drained during the process of releasing cold air. By doing so, various problems occur, such as corrosion and odors and bacteria breeding. In particular, when the pitch is designed large in order to smooth the flow of air passing through the inside, the inclination angle of the flat plate is lowered, which causes more serious problems as described above.

The present invention has been proposed to solve the above problems, heat exchanger efficiency can be increased by increasing the surface area while maintaining a constant pitch, the heat generated for the surface is configured to be more smoothly drained The purpose is to provide a heat radiating fin.

Heat dissipation fin for heat exchanger according to the present invention for achieving the above object,

The floor and the valley are alternately arranged in a curved or bent plate shape, and the adjacent floors and valleys are formed as curved portions having a gradient in the arrangement direction of the floors and valleys.

Two adjacent curved portions are arranged such that the gradient extension lines intersect each other.

The gradient centers of each curved portion are arranged in a line.

Each curved portion is arranged at equal intervals.

Two or more curved portions formed to have a gradient in the lateral direction and arranged up and down;

A connecting portion connecting two adjacent curved portions;

A tube insertion hole formed in the connection portion;

.

The inlet of the tube insertion hole is formed with a protrusion that projects laterally.

At the upper end of the curved portion located at the uppermost side and the lower side of the curved portion located at the lowermost portion, a tube seating portion on which the bottom or upper surface of the tube is seated is formed.

The curved portion is formed with a louver.

Heat dissipation fin for heat exchanger according to the present invention, since the portion connecting the floor and the valley is formed in the curved portion in the lateral direction can increase the surface area while maintaining a constant pitch, so that the probability that the inlet air causes vortex Not only is the heat exchange efficiency increased, but water generated on the surface can be drained more smoothly.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 is a perspective view of the heat dissipation fin for heat exchanger according to the present invention, Figure 4 is a perspective view showing the mounting structure of the heat dissipation fin for heat exchanger according to the present invention.

Heat dissipation fin 100 for the heat exchanger according to the present invention, as shown in Figure 3 is formed in a curved or bent plate shape so that the floor 110 and the valley 120 are alternately arranged, as shown in Figure 4 The floor 110 and the valley 120 are mounted to be bonded between two tubes 10 arranged to be spaced apart from each other. At this time, the heat dissipation fin 100 according to the present invention, such that between the neighboring floor 110 and the valley 120 is made of a curved plate, that is, between the neighboring floor 110 and the valley 120 is laterally (floored) (110) or the direction that the valleys 120 are arranged) is the largest feature in that it consists of a curved surface portion 130 having a gradient.

As described above, the heat dissipation fins 100 according to the present invention are manufactured by the curved portion 130 having the gradient connecting the floor 110 and the valley 120, as shown in FIG. 1. ) And valleys 120, 24, even if the portion having the same pitch as compared to the conventional heat radiation fins 100, 20 is produced in a flat plate shape, there is an advantage that the heat radiation efficiency is improved. Even when a portion connecting the floor 110 and the valley 120 is made of the curved portion 130, such as the heat dissipation fin 100 according to the present invention, the curved portion 130 may further increase the surface area of the louver. 140 (Louver) may be formed. Since the louver 140 is substantially the same as the conventional louvers 140 and 26 shown in FIGS. 1 and 2, a detailed description thereof will be omitted.

On the other hand, when the draft direction of the neighboring curved surface portion 130 is opposite to each other, there is a possibility that the two neighboring curved surface portion 130 are in contact with each other, it is preferable that each curved surface portion 130 is configured to have a gradient in the same direction. .

In addition, when the portion connecting the floor 110 and the valley 120 is formed as the curved portion 130, the streamline of air flowing from the outside and flowing through the surface of the curved portion 130 forms a curve. As shown, the vortex of the air is more likely to occur than the case where the portions connecting the floors 110 and 22 and the valleys 120 and 24 are formed in a flat plate. As such, when the vortex occurs in the flow of air passing through the cooling fins, the time for the air to contact the heat radiating fins 100 is increased, so that the heat exchange rate is increased, and the moisture formed on the surface of the radiating fins 100 flows down and drains more easily. There is an advantage that the corrosion and odor generation, bacteria propagation, etc. of the heat radiation fin 100 is reduced.

On the other hand, the curved surface portion 130 having a gradient in the lateral direction is different from the inclination of the upper side and the lower side, the curved surface portion 130 (for example, the leftmost curved portion 130 in the leftmost in Figure 3) Moisture formed in the upper side is more easily flowed down, and the moisture formed in the lower side is also combined with the upper moisture flowing down to discharge downward, so that the amount of moisture formed on the surface is significantly reduced. Of course, although the upper slope is relatively gentle and the lower slope is urgent, the curved portion 130 (for example, the second curved portion 130 from the left in FIG. 3) may have a relatively low moisture content. Since the moisture bound on the lower side is easily flowed down, the amount of moisture bound on the surface of the heat dissipation fin 100 is reduced without falling down compared to the conventional case shown in FIG. 1.

5 is a perspective view of a heat dissipation fin 100 for a heat exchanger according to the second embodiment of the present invention, Figure 6 is a perspective view showing a mounting structure of the heat dissipation fin 100 for heat exchanger according to the second embodiment of the present invention.

As shown in FIGS. 3 and 4, the two neighboring curved portions 130 are arranged such that the gradient extension lines intersect each other, that is, the inclination of the odd-numbered curved portion 130 and the even-numbered curved portion 130 is increased. They may be arranged in a zigzag shape so as to be different from each other, and as shown in FIGS. 5 and 6, the slopes of all curved portions 130 are the same, that is, the gradient centers of the curved portions 130 are arranged in a row. It may be.

3 and 4, if the curved portion 130 is to be arranged in a zigzag shape, the process of bending the flat plate portion of the conventional heat sink fins 100 and 20 shown in FIGS. 1 and 2 to one side. Since only the heat dissipation fins 100 according to the present invention can be manufactured, there is an advantage that the heat dissipation fins 100 and 20 can be manufactured as well as the heat dissipation fins 100 can be manufactured without major design changes.

On the contrary, if the heat radiation fins 100 according to the present invention are manufactured to have the same inclination of all curved portions 130 as shown in FIGS. 5 and 6, the curved portion 130 is illustrated in FIGS. 3 and 4. Compared to the case in which the zigzag shape is arranged, the gradient of the curved portion 130 is larger, and thus, the surface area is further increased.

In addition, as shown in FIGS. 5 and 6, when the inclinations of all the curved portions 130 are manufactured to be the same, the gap between the floor 110 and the valley 120 may be reduced. Therefore, the flow rate of air passing through the floor 110 and the valley 120 is increased, and thus, the heat exchange rate of the floor 110 and the valley 120 is improved.

On the other hand, each curved portion 130 is preferably arranged at equal intervals so that the same amount of air passes between each curved portion 130.

7 is a perspective view of a third embodiment of the heat dissipation fin 100 for a heat exchanger according to the present invention, and FIG. 8 is a perspective view showing a mounting structure of the third embodiment of the heat dissipation fin 100 for a heat exchanger according to the present invention.

In the heat dissipation fin 100 for a heat exchanger according to the present invention, two or more curved portions 130 may be arranged laterally, as shown in FIGS. 3 to 6, and the vertical direction as illustrated in FIGS. 7 and 8. It may be arranged as.

That is, the heat dissipation fin 100 according to the present invention includes two or more curved portions 130 formed to have a gradient in the lateral direction and arranged up and down, and a connecting portion 150 connecting two neighboring curved portions 130. It can be configured. At this time, the tube insertion hole 160 is formed in the connecting portion 150 so that the tube 10 extending in the horizontal direction can be inserted.

As such, when two or more curved portions 130 are arranged up and down and the tube 10 is mounted to penetrate the heat dissipation fin 100, there is an advantage in that the coupling force between the heat dissipation fin 100 and the tube 10 is greatly improved. In addition, when the tube 10 is configured to be inserted into the tube insertion hole 160 in a fitting manner, a separate process for adhering the heat dissipation fin 100 and the tube 10 may be omitted.

At this time, if the connecting portion 150 is formed in a plate shape and the tube insertion hole 160 is formed in a simple through-hole shape, when the tube 10 is inserted into the tube insertion hole 160, the tube 10 and the heat radiation fins The contact area between the 100 is very narrow, there is a fear that the heat transfer is not made smoothly. Therefore, the inlet of the tube insertion hole 160 is preferably protruded in the lateral direction is formed protruding portion 165 in close contact with the outer peripheral surface of the tube 10 is inserted into the tube insertion hole 160.

The length of the protrusion 165 may be changed according to various conditions. That is, the protrusion 165 may be extended by a length that can be spaced apart from the other neighboring connection portion 150 laterally, as shown in this embodiment, it is extended long to contact the other adjacent connection portion 150 May be In this case, when the protrusion 165 extends long to be in contact with another neighboring connection part 150, the protrusion 165 serves as a spacer for maintaining a constant distance between two laterally curved surfaces 130. Can also be with.

On the other hand, the tube seating portion 170 on which the bottom or the upper surface of the tube 10 is seated is formed at the upper end of the curved portion 130 located at the uppermost side and the lower side of the curved portion 130 located at the lowermost side. At this time, the tube seating portion 170 is preferably formed in a curved shape so that the side end so that the tube 10 can be securely seated, that is, to wrap a portion of the side surface of the tube (10).

As mentioned above, although this invention was demonstrated in detail using the preferable embodiment, the scope of the present invention is not limited to a specific embodiment, Comprising: It should be interpreted by the attached Claim. In addition, those skilled in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.
