Description

자동차의 냉각장치Cooling system of automobile

본 발명은 엔진을 냉각하여 과열을 방지함과 동시에 적온으로 유지시키는 자동차의 냉각장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cooling apparatus for an automobile which cools an engine to prevent overheating and keeps the engine at a proper temperature.

일반적으로 자동차의 냉각장치는 도1 및 도2에 도시한 바와 같이, 온도가 높은 물의 열을 외기에 전달하여 냉각시키며 자동차의 전방부에 장착된 라디에이터(1)와, 상기 라디에이터(1)내의 물을 냉각시킬 수 있도록 송풍력을 발생하는 냉각팬(3)과, 상기 냉각팬(3)에 의해 발생되는 송풍력이 증대되도록 공기의 흐름을 가이드함과 동시에 상기 냉각팬(3)을 외부의 충격으로 부터 보호할 수 있도록 상기 냉각팬(3)에 외감됨과 동시에 상기 라디에이터(1)에 나사결합되는 슈라우드(2)와, 상기 냉각팬(3)의 중심축에 삽입됨과 동시에 풀리어셉블리(5)와 그 일측이 결합되어 상기 라디에이터(1)로 통과되는 공기의 온도에 따라 상기 냉각팬(3)의 회전 속도를 자동적으로 조절하는 자동냉각팬커플링(4)과, 상기 풀리어셉블리(5)의 워터펌프풀리(5a)와 크랭크축풀리(5b)가 벨트(6)를 매개로 함께 회전하면서 상기 워터펌프풀리(5a)의 일측에 결합된 냉각수를 순환시키는 워터펌프(7)로 이루어져 있다.1 and 2, a cooling device for an automobile generally includes a radiator 1 mounted on a front portion of an automobile, which conveys heat of high temperature water to the outside air and cools the water inside the radiator 1, (3) for generating a blowing force so as to cool the cooling fan (3), and a cooling fan (3) for guiding the flow of air to increase the wind power generated by the cooling fan A shroud 2 which is inserted into the center shaft of the cooling fan 3 and which is inserted into the radiator 1 while being externally exposed to the cooling fan 3 so as to be protected from the cooling fan 3, An automatic cooling fan coupling 4 coupled to one side of the cooling fan 3 and automatically controlling the rotational speed of the cooling fan 3 according to the temperature of the air passing through the radiator 1, 5, the water pump pulley 5a and the crankshaft pulley 5b While rotating with the bit 6, the medium consists of a water pump (7) for circulating the cooling water coupled to one side of said water pump pulley (5a).

그러나, 이와 같이 구성된 자동차의 냉각장치는 크랭크축으로 부터 동력을 전달받은 상기 크랭크축풀리(5b)는 벨트(6)를 매개로 상기 냉각팬(3) 및 워터펌프(7)를 회전시켜 상기 라디에이터(1)를 냉각시키게 되는 바, 상기 냉각팬(3)의 중심부에는 자동냉각팬커플링(4)이 설치되어 있어 저속에서는 엔진의 회전수와 거의 같은 속도로 회전하고 고속이 되어 라디에이터(1)를 통과하는 공기의 온도가 내려가면 회전수가 급격히 떨어져 엔진을 적온으로 냉각하게 되나 워터펌프(7)와 함께 회전하는 구조로 되어 있어 자동차가 고속으로 주행시에는 유입풍에 의한 냉각이 이루어지나 저속일 경우에는 벨트(6)를 매개로 워터펌프(7)가 함께 회전하기 때문에 회전수를 일정 수준으로 올리지 못하여 냉각효율이 저하되는 문제점이 있었다.The crankshaft pulley 5b, which receives the power from the crankshaft, rotates the cooling fan 3 and the water pump 7 via the belt 6, An automatic cooling fan coupling 4 is provided at the center of the cooling fan 3 so that the cooling fan 3 rotates at a speed substantially equal to the number of revolutions of the engine at a low speed, When the temperature of the air passing through the water pump 7 is lowered, the number of revolutions of the engine suddenly falls and the engine is cooled down to a proper temperature. However, the structure rotates together with the water pump 7, Since the water pump 7 rotates together with the belt 6 via the belt 6, the number of revolutions can not be raised to a certain level, thereby lowering the cooling efficiency.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로써, 본 발명의 목적은 저속에서도 냉각팬의 회전수를 높여 적온으로 엔진을 냉각하여 냉각효율을 향상시킨 자동차의 냉각장치를 제공하는 데 있다.Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a cooling apparatus for an automobile having an improved cooling efficiency by cooling the engine at a proper temperature by increasing the number of revolutions of the cooling fan There is.

상기와 같은 목적을 실현하기 위하여, 본 발명에 의한 자동차의 냉각장치는, 크랭크축풀리에 벨트를 연결하여 엔진의 전방에 설치되어 회전하면서 엔진을 냉각시키는 냉각팬을 가진 자동차의 냉각장치에 있어서, 상기 냉각팬이 별도로 고정되도록 냉각팬의 일측에 고정수단을 설치하여 구성함을 특징으로 한다.In order to achieve the above object, a cooling apparatus for an automobile according to the present invention is a cooling apparatus for an automobile having a cooling fan installed at the front of an engine for connecting a belt to a crankshaft pulley and cooling the engine while rotating, And fixing means is provided on one side of the cooling fan so that the cooling fan is separately fixed.
