なものであるという問題点があった。Structure of the conventional example and its problems As shown in FIG. 4, the conventional heat exchanger is composed of plate fins 1 arranged in parallel and heat medium pipes 2 passing through these plate fins 1. , plate fin 1
is provided on a straight line with respect to the fluid flow direction indicated by the arrow. However, the above-mentioned plate fin 1
In this configuration, the temperature boundary layer formed on the plate fins 1 is thick and obstructs heat transfer, and the improvement of heat transfer due to the turbulent flow effect is limited to the heat transfer pipe 2 only, causing large turbulence to the fluid flow. There was a problem in that the heat transfer was small.

たものである。Structure of the Invention In order to achieve this object, the present invention divides a plate fin into a plurality of fin elements and arranges the fin elements non-linearly with respect to the fluid flow direction, thereby thinning the temperature boundary layer and reducing heat. In addition to improving the heat transfer coefficient, the fin elements are connected to each other, and this connecting piece disturbs the fluid flow to obtain the effect of promoting turbulence, thereby improving the heat transfer coefficient and thus improving the capacity. be.
実施例の説明
以下、本発明の一実施例を第１図〜第３図を参照して説
明する。DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

１１ｄを連結させるだめの連結片１３より成り、相互の
これらフィン素子１１ａ〜１１ｄの間には、流体が流れ
る事のできる空間を設けている。In FIGS. 1 to 3, the heat exchanger 10 is composed of a large number of plate fins 11 arranged in parallel, and heat medium pipes 12 that penetrate the plate fins 11 orthogonally. The plate fin 11 is made of aluminum or the like with good thermal conductivity, and includes a plurality of fin elements 11a to 11d arranged non-linearly with respect to the fluid flow direction shown by the arrow, and mutually arranged fin elements 11a to 11d.
The fin element 11d is made up of a connecting piece 13 for connecting the fin elements 11a to 11d, and a space through which fluid can flow is provided between the fin elements 11a to 11d.
上記構成においてプレートフィン１１は流体の流れに対
しフィン素子１１ａ〜１１ｄに分断されるため境界層前
縁効果によυ熱伝達の向上が割れ、なお、かつフィン素
子１１ａ〜１１ｄが流体の流れに対し非直線上に配列さ
れるため、フィン素子同士の温度境界層の影響を受けな
くなり温度境界層が薄くなり熱伝達率の向上が計れる。In the above configuration, the plate fin 11 is divided into fin elements 11a to 11d with respect to the fluid flow, so that the improvement in υ heat transfer is lost due to the boundary layer leading edge effect. On the other hand, since the fin elements are arranged non-linearly, they are not affected by the temperature boundary layer between the fin elements, and the temperature boundary layer becomes thinner, thereby improving the heat transfer coefficient.
しかも、相互のこれらフィン素子１１ａ〜１１ｄを連結
する連結片１３に、流体の流れが当り、流れを乱し、乱
流促進効果が得られ、熱伝達率の向上が計れるものであ
る。Moreover, the flow of fluid hits the connecting pieces 13 that connect the fin elements 11a to 11d, turbulating the flow, producing an effect of promoting turbulent flow, and improving the heat transfer coefficient.
従って、流体の流れに対し、非直線上に配列されフィン
素子１１ａ〜１１ｄに分断され相互のこれらフィン素子
１１ａ〜１１ｄが連結片１３により連結されたプレート
フィン１１を用いる事で、温度境界層を薄くし熱伝達率
の向上を計り、かつ、乱流促進効果によっても能力の大
幅な向上が計れるという効果が得られる。Therefore, by using the plate fin 11 which is arranged non-linearly and divided into fin elements 11a to 11d, and these fin elements 11a to 11d are connected by a connecting piece 13, the temperature boundary layer can be suppressed. By making it thinner, the heat transfer coefficient can be improved, and the turbulence promotion effect can significantly improve the performance.

れるものである。Effects of the Invention As is clear from the above description, the present invention provides a method for dividing the fluid flow into fin elements arranged in a non-linear manner.
With plate fins in which mutual fin elements are connected by connecting pieces, the heat transfer coefficient is significantly improved due to the leading edge effect of the boundary layer due to the separated fin elements and the turbulence promoting effect due to the connecting pieces, resulting in a significant improvement in capacity. This has the effect of being measurable.
