Abstract

PURPOSE:To enable a heat radiation efficiency at the first louver to be improved by a method wherein a spacing between a flat part at an upstream side end and the first louver in a group of louvers at the upstream side is made larger than that of other louvers. CONSTITUTION:As air flows from an upstream side, the air is divided into one flowing from an opening between a flat part 12 at an upstream side end and the first louver 14A in a group 14 of louvers, the other flowing from a louver 4B rear of it or another flow flowing from the other flow and their directions are changed by each of louvers 18. The air is flowed toward a downstream side as a descending flow and further flows toward fins 10 for a heat exchanger, its flow direction is changed from a location of a central louver 15 toward an upstreams flow and then the air flows toward a downstream side. At this time, since a space L between a louver 12A forming an interface part with the group 14 of the louvers at the upstream side at the flat part 12 at the upstream side end and the first louver 14A in the group 14 of the upstream side louvers is made larger than that of other louvers, the air may easily flow into this location and a heat radiation efficiency of the first louver 14A can be improved.

、エンジンファンによって風を吸引できるため、コアの
通気抵抗は、問題が少なかった。As is well known, in a type where the radiator is cooled by an engine fan, even if the core's ventilation resistance is a little high, the engine fan can suck in air, so the core's ventilation resistance is less of a problem.

いる。その際、モータ容量の制限や経済性の観点から、
小型のモータを使用せざるを得ない状況にある。Therefore, a motor fan is attached to the radiator and the radiator is cooled by the motor fan. At that time, from the viewpoint of motor capacity limitations and economic efficiency,
There is no choice but to use a small motor.

このように小型のモータによってラジェータを冷却する
ためには、放熱量を大きくして、通気抵抗の小さいコア
を開発する必要がある。In order to cool the radiator with such a small motor, it is necessary to develop a core with a large amount of heat dissipation and low ventilation resistance.

ある。The heat exchanger fin 1 is provided on a fin board 2 provided along the flow direction of air flowing between the tubes 8, with flat portions 2A and 2B left at the windward fallen end and the leeward end. A louver group 4 formed by carving a large number of single-roof-like louvers 3 with opposite inclination directions on the lee side and on the same standard vA6.
．． 5, and a central louver 7 is formed at the boundary between the louver group 4 on the windward side and the louver group 5 on the leeward side.

熱交換器コアの冷却を行なう。In such a heat exchanger fin 1, the air flowing in from the windward side louver is changed in direction by each louver 3, and flows downward toward the leeward side, while also flowing toward the heat exchanger fin l below. The flow changes from the center louver 7 to an upward flow and flows toward the leeward side. During this time, the inflowing air comes into contact with the louvers 3 in each louver group 4.5, and thereby removes heat from the heat exchanger core transmitted from the cooling water flowing down the tubes 8.
Cools the heat exchanger core.

The louver group 4.5 is formed by carving a large number of louvers on the same reference line 6, so as shown in FIG. Since the inflow air region B formed by the first louver 4A in group 4 is small, the amount of air flowing into the inflow air region B formed by the flat portion 2A and the first louver 4A is small. Heat dissipation efficiency decreases. In addition, the air flow in the first louver 4A in the windward louver group 4 is not along the louver angle θ compared to the later louvers 4B, 4C, etc., so the heat radiation efficiency is lowered. There is a problem with the decline.

ーバ５Ｘに於ても、空気の流れがルーバ角度θに沿って
いないため、放熱効率が低下するという問題がある。This phenomenon poses a problem in that even in the last louver 5X in the louver group 5 on the leeward side, the air flow does not follow the louver angle θ, so that the heat dissipation efficiency decreases.

更に、この現象は、中央ルーバ７に於ても、空気の流れ

徴とする熱交換器用フィン。(5) A single-roof-shaped louver with the windward end and the leeward end having opposite inclination directions is placed on the same reference line on the fin board installed along the direction of air flow between the tubes. In the heat exchanger fin, which forms a group of louvers with a large number of carved grooves, and a central louver is formed at the boundary between the louver group on the windward side and the louver group on the leeward side, the distance between the flat part of the center louver and the first louver of the louver group on the windward side, the respective distances between the louvers located immediately before and after the center louver on the windward and leeward sides, and the leeward end of the central louver. A fin for a heat exchanger, characterized in that a distance between the flat part of the fin and the last louver of the louver group on the leeward side is larger than other louver intervals.
