Abstract: PURPOSE: A heat exchanger is provided to improve the energy efficiency by employing heat radiation fins of an elliptical shape so as to make the heat transfer smooth. CONSTITUTION: A heat exchanger(100) comprises a pipe(10) in which a fluid flows and a plurality of heat radiation fins(20) which are formed on the exterior of the pipe so that heat exchange takes place between the fluid flowing in the pipe and the fluid flowing around the heat radiation fins. The heat radiation fins are formed of a thin metal material in an elliptical shape, wherein the long axis is arranged to be perpendicular to the flow of the fluid flowing outside the radiating fins.

Abstract: PURPOSE: A fin-tube heat exchanger is provided to ensure smooth heat exchange at the fins located in the downstream side of a pipe because bent surfaces gather the flow of fluid to the downstream side. CONSTITUTION: A fin-tube heat exchanger(100) comprises a pipe(10) in which fluid flows and a plurality of fins(20) formed of metal plates and vertically arranged on the pipe. Heat exchange is made between the fluid flowing inside the pipe and the fluid passing by the outside of the fins. Each fin has a first bent surface(30) on an edge and a second bent surface(40) which is separate from the first bent surface.
Abstract translation: 目的：提供翅片管热交换器，以确保位于管道下游侧的翅片的平滑热交换，因为弯曲的表面将流体流向下游侧。 构成：翅片管热交换器（100）包括其中流体流动的管道（10）和由金属板形成并垂直布置在管道上的多个翅片（20）。 在管道内流动的流体和通过翅片外部的流体之间进行热交换。 每个翅片具有在边缘上的第一弯曲表面（30）和与第一弯曲表面分离的第二弯曲表面（40）。

Abstract: PURPOSE: A louver fin and a heat exchanger having the same are provided to increase amount of heat transfer and reduce a drop of air pressure by forming a dimple on a corrugated part and a flat part with changing a manufactured mold. CONSTITUTION: A heat exchanger comprises a body(110), a plurality of louvers(120), dimples(130), a louver fin(100), and a tube. The body is formed into a thin plate and comprises a corrugated part and a flat part. The louver is formed on each inclined plane. The dimple is protruded toward an inner side of the body from the corrugated part and the flat part. The dimple has a width along a depth of the corrugated part or the flat part of the body. The louver fin comprises the inclined plane which is gradually branched to a direct path of gas passing through the body. The tube is connected along the corrugated part and the flat part of the louver fin.
Abstract translation: 目的：提供一个百叶窗和一个具有该热交换器的热交换器以增加传热量并通过在改变制造的模具上在波纹部分和平坦部分上形成凹坑来减小空气压力的下降。 构成：热交换器包括主体（110），多个百叶窗（120），凹坑（130），百叶窗（100）和管。 本体形成为薄板，包括波纹部分和平坦部分。 百叶窗形成在每个倾斜平面上。 凹坑从波纹部分和平坦部分向主体的内侧突出。 凹坑具有沿波纹部分或身体的平坦部分的深度的宽度。 百叶窗包括倾斜平面，其被逐渐分支到通过本体的气体的直接路径。 管沿着波纹部分和百叶窗的平坦部分连接。
