Description

차량용 냉각모터 냉각시스템{Cooling Motor Cooling System for Vehicle}Cooling Motor Cooling System for Vehicles

본 발명은 차량의 냉각장치에 장착된 모터의 과열을 방지하기 위한 냉각시스템에 관한 것으로서, 특히 냉각팬의 회전축과 워터펌프의 회전축이 일체로 구성된 냉각장치의 모터 및 엔진을 냉각시킬 수 있게 구성한 것이다.
The present invention relates to a cooling system for preventing overheating of a motor mounted on a cooling device of a vehicle, and is particularly configured to cool a motor and an engine of a cooling device in which a rotation shaft of a cooling fan and a rotation shaft of a water pump are integrally formed. .

엔진에 의해 구동하는 차량에는 엔진 냉각시스템이 구비된다.The vehicle driven by the engine is provided with an engine cooling system.

통상적인 차량의 엔진 냉각시스템은 엔진에서 가열된 냉각수를 라디에이터에서 냉각하여 엔진으로 재순환시키는 구조이다. 엔진룸에는 냉각팬이 장착되며 냉각팬은 차량 밖의 공기를 라디에이터로 강제 흡입하여 라디에이터에서 냉각수의 열을 방열한다. 그리고 냉각된 냉각수는 워터펌프를 통해 엔진 내부를 순환하면서 엔진의 열을 낮춘다.In a typical vehicle engine cooling system, a cooling water heated in an engine is cooled in a radiator and recycled to the engine. The engine room is equipped with a cooling fan, which cools the air outside the vehicle to the radiator to dissipate the heat of the coolant from the radiator. The cooled coolant circulates inside the engine through the water pump to lower the heat of the engine.

최근에는 냉각팬의 구동과 워터펌프의 구동을 하나의 모터로 구동시킨다. 즉 모터의 회전축의 일단에는 냉각팬을 장착하고 회전축의 타단에는 워터펌프의 임펠러를 장착하여 모터의 구동에 의해 팬이 회전하고 라디에이터를 통과하며 냉각된 냉각수가 워터펌프에 의해 순환하는 구조이다.Recently, the driving of the cooling fan and the driving of the water pump are driven by one motor. That is, the cooling fan is mounted at one end of the rotating shaft of the motor and the impeller of the water pump is mounted at the other end of the rotating shaft so that the fan rotates by driving the motor, passes through the radiator, and the cooled cooling water is circulated by the water pump.

이와 같이 구성된 차량의 냉각시스템에 있어서, 냉각시스템의 모터 자체에서 발생한 열 및 엔진에서 전도된 열을 냉각시킬 수 있도록 종래에는 모터 하우징에 방열핀을 장착하거나 모터의 인가되는 전류를 제한하여 발열량을 최소화하는 방식을 채택하였다.In the cooling system of the vehicle configured as described above, in order to cool the heat generated from the motor itself of the cooling system and the heat conducted from the engine, a heat radiating fin is mounted on the motor housing or the current applied by the motor is limited to minimize the amount of heat generated. Adopted the method.

그러나 방열핀을 장착한 경우에 모터의 크기가 커져 협소한 엔진룸 내부 공간의 활용도가 떨어지며 또한 공냉방식의 경우에는 엔진룸 내부가 협소하여 방열이 원활하게 이루어지지 않는다는 단점이 있다.However, when the heat radiation fins are mounted, the size of the motor is increased, so that utilization of a narrow space inside the engine room is reduced, and in the case of the air cooling method, the inside of the engine room is narrow and heat dissipation is not performed smoothly.

또한, 전류를 제한할 경우에는 모터 효율이 떨어지는 단점이 있다. 이와 같은 문제점을 극복하기 위해서 종래에는 모터의 출력 자체를 낮추거나 혹은 모터 직결 구동이 어려워 벨트 또는 체인과 같은 동력전달수단을 이용하여 동력을 전달하였다.
In addition, when the current is limited, there is a disadvantage in that the motor efficiency is lowered. In order to overcome this problem, conventionally, the output of the motor itself is lowered or the motor is directly connected to the drive, and thus power is transmitted using a power transmission means such as a belt or a chain.

아래에서는 본 발명에 따른 차량용 냉각모터의 냉각시스템의 양호한 실시예를 첨부한 도면을 참조로 하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings a preferred embodiment of a cooling system of a vehicle cooling motor according to the present invention will be described in detail.

도면에서, 도 1은 본 발명의 한 실시예에 따른 차량용 냉각모터의 냉각시스템을 나타낸 개념도이고, 도 2a 및 도 2b는 도 1에 도시된 냉각시스템의 냉각수 순환경로를 나타낸 개념도이다.1 is a conceptual diagram showing a cooling system of a vehicle cooling motor according to an embodiment of the present invention, Figures 2a and 2b is a conceptual diagram showing a cooling water circulation path of the cooling system shown in FIG.

도 1에 도시된 바와 같이, 냉각모터(120)의 회전축(120S)의 일단에는 냉각팬(121)이 장착되고, 회전축(120S)의 타단에는 워터펌프(130)의 임펠러(131)가 장착된다. 그리고 냉각모터(120)의 둘레는 워터자켓(123)이 감싸여 장착된다.As shown in FIG. 1, a cooling fan 121 is mounted at one end of the rotating shaft 120S of the cooling motor 120, and an impeller 131 of the water pump 130 is mounted at the other end of the rotating shaft 120S. . And the circumference of the cooling motor 120 is wrapped around the water jacket 123 is mounted.

한편, 라디에이터(110)에서 배출된 냉각수는 워터자켓(123)으로 유입되고, 워터자켓(123)을 통해 워터펌프(130)로 유입된 후 워터펌프(130)의 임펠러(131)에 의해 엔진(140) 내부로 유입된다. 엔진(140)으로 유입된 냉각수는 엔진(140)의 열을 흡열한 후에 엔진(140) 외부로 배출되는데, 엔진(140) 외부로 배출된 냉각수는 써모스탯(150)으로 유입된 후 써모스탯(150)에서 라디에이터(110)로 유동하거나 또는 써모스탯(150)에서 워터펌프(130)로 연장된 분기관(160)을 통해 워터펌프(130)로 유입된다.Meanwhile, the coolant discharged from the radiator 110 flows into the water jacket 123, flows into the water pump 130 through the water jacket 123, and then the engine by the impeller 131 of the water pump 130. 140) flows into the interior. The coolant introduced into the engine 140 absorbs heat from the engine 140, and then is discharged to the outside of the engine 140. 150 flows to the radiator 110 or flows into the water pump 130 through a branch pipe 160 extending from the thermostat 150 to the water pump 130.

여기에서 써모스탯(150)은 엔진(140)에서 배출되는 냉각수의 온도를 측정하고 측정된 온도가 설정된 온도보다 낮을 경우에는 분기관(160)으로 냉각수를 유동시키고, 측정된 온도가 설정된 온도를 초과할 경우에는 라디에이터(110)로 냉각수를 유동시킨다.Here, the thermostat 150 measures the temperature of the coolant discharged from the engine 140, and when the measured temperature is lower than the set temperature, flows the coolant to the branch pipe 160, and the measured temperature exceeds the set temperature. In this case, the coolant flows to the radiator 110.

이와 같이 구성된 냉각수 순환라인에 있어서, 도 2a에 도시된 바와 같이, 라디에이터(110)에서 냉각된 냉각수는 워터자켓(123), 워터펌프(130), 엔진(140), 써모스탯(150)으로 유동한다. 그리고 써모스탯(150)에서 냉각수 온도가 설정된 온도를 초과할 경우 냉각수를 라디에이터(110)로 유동시켜 냉각수를 냉각시키는 순환구조를 갖는다.In the cooling water circulation line configured as described above, as shown in FIG. 2A, the cooling water cooled in the radiator 110 flows into the water jacket 123, the water pump 130, the engine 140, and the thermostat 150. do. And when the cooling water temperature in the thermostat 150 exceeds the set temperature has a circulation structure for cooling the cooling water by flowing the cooling water to the radiator 110.

반면에, 엔진(140)에서 써모스탯(150)으로 유입된 냉각수 온도가 설정된 온도보다 낮을 경우에는 도 2b에 도시된 바와 같이, 분기관(160)을 통해 냉각수를 워터펌프(130)로 유동시켜 냉각수가 엔진(140)으로 유입되게 함으로써, 엔진(140)을 냉각시킨다.On the other hand, when the coolant temperature introduced from the engine 140 to the thermostat 150 is lower than the set temperature, as shown in Figure 2b, by flowing the coolant to the water pump 130 through the branch pipe (160) By allowing the coolant to flow into the engine 140, the engine 140 is cooled.

이와 같이 본 발명에 따른 냉각모터 냉각시스템은 엔진(140)에서 배출되는 냉각수의 온도에 따라 냉각수의 경로를 변환하며 또한 냉각모터(120)에 장착된 워터자켓(123)으로 냉각모터(120)를 수냉함으로써, 방열핀의 구성이 필요치 않아 냉각모터(120)의 부피를 줄여 엔진룸의 공간활용도를 증대시킬 수 있다.
As described above, the cooling motor cooling system according to the present invention converts the path of the cooling water according to the temperature of the cooling water discharged from the engine 140, and also uses the water jacket 123 mounted on the cooling motor 120 to cool the cooling motor 120. By water cooling, since the configuration of the heat radiation fins is not necessary, the volume of the cooling motor 120 can be reduced to increase the space utilization of the engine room.
