본 고안은 수냉식 엔진 냉각장치용 슈라우드에 관한 것이다.The present invention relates to a shroud for a water-cooled engine cooler.
엔진의 실린더내의 연소가스는 2000℃ 이상이고 이 열의 상당한 양이 실린더, 실린더헤드, 피스톤, 밸브 등에 전도되어 그 온도가 과도하게 높아지면 재료의 강도가 저하되어 고장을 일으키거나 수명이 단축되고 연소상태도 나빠져서 노킹 또는 조기점화가 발생되어 출력과 연비 등 엔진의 성능에 영향을 미치고 있다.The combustion gas in the cylinder of the engine is over 2000 ℃ and a considerable amount of heat is conducted to the cylinders, cylinder heads, pistons, valves, etc., and the temperature is excessively high. It also worsens, knocking or premature ignition, affecting engine performance such as power and fuel economy.
따라서 실린더내의 연소가스를 실린더 블록과 실린더 헤드에 물재킷을 형성하여 상기 물재킷에 냉각수를 순환시켜서 냉각작용을 하도록 하고, 가열된 냉각수의 보유열을 라디에이터에서 방열시킬 때 외부공기를 냉각팬에 의하여 라디에이터를 통하여 강제적으로 흡입하고, 팬이 흡입하는 공기가 라디에이터를 통과하도록 라디에이터에는 슈라우드가 설치되어 있다.Accordingly, the combustion gas in the cylinder is formed in the cylinder block and the cylinder head to circulate the cooling water in the water jacket to circulate the cooling water, and when the heat of the heated cooling water is radiated from the radiator, the external air is cooled by the cooling fan. The radiator is provided with a shroud so as to force suction through the radiator and allow the air sucked by the fan to pass through the radiator.
그러나 상용차와 같이 용량이 큰 엔진을 탑재한 차량의 경우에는 슈라우드는 라디에이터에 설치되어 있고, 팬은 크랭크축에 의하여 회전하도록 설치되므로서 제3도에 도시한 바와 같이 팬(10)의 반경방향 중심선이 라디에이터(11)에 고정된 슈라우드(12)의 흡입공기 출구측과 일정한 간극(t)을 두고 설치되어 있어 팬(10)에 의하여 흡입되는 공기가 라디에이터(11)를 통과하는 공기 이외에 상기 간극(t) 사이로 흡입되는 공기가 존재하므로서 팬(4)의 용량에 비하여 라이에이터의 방열성능이 양호하지 못한 문제점이 있는 것이다.However, in the case of a vehicle equipped with a large engine such as a commercial vehicle, the shroud is installed in the radiator, and the fan is installed to rotate by the crankshaft, so that the radial center line of the fan 10 is shown in FIG. The radiator 11 is provided with a predetermined gap t with a suction air outlet side of the shroud 12 fixed to the radiator 11 so that the air sucked by the fan 10 passes through the radiator 11 in addition to the air gap. Since there is air sucked between t), there is a problem in that the heat dissipation performance of the writer is not good compared to the capacity of the fan 4.
한편 최근 들어서 차량의 상품성 향상을 위한 신기술의 적용으로 인하여 엔진실의 구조는 복잡하여지고 엔진은 고출력화 하는 경향이 있으므로 이에 부응하기 위하여 라디에이터의 전면에는 인터쿨러, 오일쿨러, 등의 공기저항체를 설치하므로서 압력손실이 증가되어 라디에이터의 방열성능이 더욱 저하되고 있는 실정이다.On the other hand, in recent years, due to the application of new technology for improving the commercialization of the vehicle, the structure of the engine compartment is complicated and the engine tends to be high output. The pressure loss is increased, the heat radiation performance of the radiator is further reduced.
상기한 실정을 감안하여 라디에이터의 용량을 증대하고 있으나 이는 설치장소의 확보문제, 차량의 중량증가 및 비용상승요인을 내포하고 있는 것이다.In consideration of the above situation, the capacity of the radiator is increasing, but this includes problems of securing an installation place, weight increase of the vehicle, and cost increase factors.
본 고안은 상기한 실정을 감안하여 차량의 중량증가 및 비용상승 요인이 없이 라디에이터의 방열성능을 향상시킨 수냉식 엔진 내각장치용 슈라우드를 제공하는 것을 목적으로 한다.The present invention aims to provide a shroud for a water-cooled engine cabinet that improves the heat dissipation performance of a radiator without the weight increase and cost increase factors of the vehicle in view of the above situation.
본 고안은 상기한 목적을 달성하기 위하여 라디에이터에 고정되는 슈라우드 본체에 홈을 형성하여 팬이 내부에 수용될 수 있는 길이를 가진 팬커버를 삽입 고정하여서 된 것이다.The present invention is to form a groove in the shroud body is fixed to the radiator to achieve the above object by inserting and fixing a fan cover having a length that can be accommodated inside the fan.
이하 실시예를 도면에 의하여 설명한다.Embodiments will be described below with reference to the drawings.
본 고안은 제1도 및 제2도에 도시한 바와 같이 라디에이터(1)에 고정되는 슈라우드 본체(2)에 홈(3)을 형성하여 크랭크축(미도시)에 의하여 회전되는 팬(4)이 내부에 수용될 수 있는 길이를 가진 팬커버(5)를 삽입 고정하여서 된 것이다.According to the present invention, as shown in FIGS. 1 and 2, the fan 4 is rotated by a crankshaft (not shown) by forming a groove 3 in the shroud main body 2 fixed to the radiator 1. The fan cover 5 having a length that can be accommodated therein is inserted and fixed.
이상과 같은 본 고안은 팬(4)의 주위에 슈라우드 본체(1)와 연결되는 팬커버(5)가 설치되어 있으므로 팬(4)의 회전에 의하여 외부공기를 강제로 흡입하여 물재킷에서 가열된 냉각수의 보유열을 라디에이터(1)에서 방열할 때 팬(4)이 흡입되는 외부공기는 전부 라디에이터(1)를 통과하므로서 방열성능이 향상되는 것이다.Since the fan cover 5 is connected to the shroud main body 1 around the fan 4, the present invention as described above is forced to suck external air by the rotation of the fan 4 to be heated in the water jacket. When the heat of the cooling water is radiated from the radiator 1, the outside air into which the fan 4 is sucked passes through the radiator 1, thereby improving heat dissipation performance.
이상과 같이 본 고안은 라디에이터의 용량은 그대로 두고 슈라우드에 팬을 수용하는 길이의 팬커버만을 설치하므로서 종래 라디에이터의 용량을 증대시키는 것에 비하여 설치장소의 애로점이 없고, 차량의 중량증가 및 비용상승이 없이 라디에이터의 방열성능이 향상되는 효과가 있는 것이다.As described above, the present invention installs only a fan cover of a length that accommodates a fan in the shroud while leaving the radiator capacity intact, and there is no trouble point in the installation place compared to increasing the capacity of the conventional radiator, without increasing the weight and cost of the vehicle. The heat radiation performance of the radiator is to improve the effect.
