Abstract
Description
The present invention relates to a heat dissipation fin for a heat exchanger and a heat exchanger provided with the heat dissipation fin, the heat dissipation for the heat exchanger having an extended heat dissipation area so that heat exchange between the fluid flowing through the heat dissipation tube of the heat exchanger and the outside air can be performed more efficiently. It relates to a heat exchanger having a fin and its heat dissipation fin.
Devices such as air conditioners, refrigerators, car air conditioners, etc. comprise a heat exchanger, a general heat exchanger is composed of components such as headers, heat radiating tubes, heat radiating fins and baffles.
1 is a view for explaining the configuration of a conventional general heat exchanger.
As shown in the drawings, the
Components such as the
2 is a view for explaining the structure of a conventional heat dissipation fin.
As shown in the figure, the
However, the heat dissipation fin, which was mounted in the conventional heat exchanger, was formed in a zigzag form by using a thin metal plate, and was installed between the heat dissipation tube and the heat dissipation tube.
The present invention has been made to solve the problems of the prior art as described above, the heat dissipation fin and the heat dissipation fin for heat exchanger to more effectively heat exchange of fluid such as cooling water flowing through the heat dissipation tube of the heat exchanger It is an object to provide a heat exchanger equipped with this.
In addition, another object of the present invention is to provide a heat dissipation fin for a heat exchanger and a heat exchanger having the heat dissipation fin, which can prevent the occurrence of condensation which causes corrosion or bacterial propagation.
The present invention configured to achieve the above object is as follows.
In the heat dissipation fin for heat exchanger is arranged between the heat dissipation tube of the heat exchanger, the thin metal plate is bent in a zigzag form, but the refraction section in contact with the heat dissipation tube is refracted in a right angle while the refraction section and The heat dissipation section between the refraction sections has a structure in which a concave portion and a convex portion are sequentially formed.
In the heat dissipation fin for heat exchanger according to the present invention, the concave portion and the convex portion may be formed in a continuous wave form.
In the heat dissipation fin for heat exchanger according to the present invention, the concave portion and the convex portion may be formed in a structure repeatedly formed at a predetermined interval.
In the heat dissipation fin for heat exchangers according to the present invention, the four sides of the heat dissipation section in which the concave portion and the block portion are formed may be formed in a flat surface.
In the heat exchanger according to the present invention, a plurality of heat dissipation tubes are arranged at regular intervals between a pair of headers facing each other, while heat dissipation fins having a thin thickness are arranged in a zigzag form at regular intervals between the heat dissipation tubes. In the heat exchanger, in which a baffle is installed at a predetermined interval to control the flow direction of the fluid flowing in the header, the heat dissipation fin is formed by refraction of a thin metal plate in a zigzag form, but the surface is formed into an uneven structure. .
According to the heat dissipation fin for the heat exchanger according to the present invention has an advantage that the heat dissipation efficiency of the fluid, such as the cooling water flowing along the inside of the heat dissipation tube can be improved as the heat dissipation area is enlarged.
According to the heat dissipation fin for heat exchanger according to the present invention, even if the heat dissipation area is enlarged, there is an effect of preventing condensation which is a cause of breeding or corrosion of bacteria.
According to the heat exchanger according to the present invention, as the heat dissipation fin having improved heat dissipation performance is provided, the performance of the heat exchanger is improved.
Hereinafter, the configuration of the heat dissipation fin for the heat exchanger according to the preferred embodiment of the present invention will be described in more detail with reference to the accompanying drawings.
