본 발명은 라디에이터 및 컨덴서를 강제 냉각시켜주는 차량용 열교환기의 쿨링팬에 관한 것으로서, 특히 쿨링팬의 회전에 의해 흡입되는 외기의 일부를 쿨링팬 모터로 재순환시켜 쿨링팬 모터의 열화를 방지하기 위한 차량용 쿨링팬 모터의 냉각구조에 관한 것이다.The present invention relates to a cooling fan of a vehicle heat exchanger for forcibly cooling the radiator and the condenser, and in particular, a vehicle for preventing deterioration of the cooling fan motor by recirculating part of the outside air sucked by the rotation of the cooling fan to the cooling fan motor. It relates to a cooling structure of a cooling fan motor.

통상, 차량(vehicle)의 엔진 냉각방식중 수냉식의 경우, 엔진을 경유한 후 고온으로 열교환된 냉각수를 외기(이하 "냉각공기"라 함)에 의해 냉각시키기 위한 라디에이터가 설치되고, 라디에이터의 후방에는 냉각공기를 강제 대류시키므로써 냉각효율을 높이기 위한 쿨링팬 및 쿨링팬 모터가 쉬라우드(shroud)에 의해 고정 설치되어 있다.Usually, in the case of water-cooling in the engine cooling method of a vehicle, a radiator is installed for cooling the coolant heat exchanged to a high temperature after passing through the engine by outside air (hereinafter referred to as "cooling air"), and is provided at the rear of the radiator. A cooling fan and a cooling fan motor are fixedly installed by shrouds to increase cooling efficiency by forced convection of the cooling air.

상기 쿨링팬의 구동수단으로서 쉬라우드의 모터 마운트에 지지 고정되는 쿨링팬 모터는 통상, 엔진에 근접하게 설치되기 때문에 엔진열에 의한 열화로 손상 및 오동작의 우려가 있다. 이를 방지하기 위한 수단으로서, 쿨링팬 모터의 엔진측에 차열판, 이른바 히트쉴드(heat shield)를 설치하므로써 엔진열이 쿨링팬 모터로 전도되는 것을 방지하는 기술이 일반적으로 공지되어 있다.Since the cooling fan motor supported and fixed to the motor mount of the shroud as the driving means of the cooling fan is normally installed in close proximity to the engine, there is a risk of damage and malfunction due to deterioration by engine heat. As a means for preventing this, there is generally known a technique for preventing the engine heat from being conducted to the cooling fan motor by providing a heat shield plate, a so-called heat shield, on the engine side of the cooling fan motor.

구체적으로, 히트쉴드가 적용된 쿨링팬 모터의 일실시예로서, 도 1에 도시된 일본실용신안공보 소62-799에 의하면 쿨링팬 모터(1)의 케이스(3)와 쉬라우드(2) 사이에 냉기통로(5)를 갖는 히트쉴드(7)가 설치되되, 히트쉴드(7)의 일측으로 쿨링팬(9)을 향해 개구된 도입부(11)를 형성하고 히트쉴드의 타측에는 배출구(13)를 형 성하므로써 쿨링팬(9)으로부터 송풍되는 냉각공기의 일부가 도입부(11)를 통해 냉기통로(5)로 유입되어 쿨링팬 모터(1)를 냉각시킨 후 배출구(13)를 통해 배출되도록 하는 냉각공기 재순환과정을 통해 쿨링팬 모터(1)의 열화를 방지토록 하였다.Specifically, according to one embodiment of the cooling fan motor to which the heat shield is applied, according to Japanese Utility Model Publication No. 62-799 shown in FIG. 1, between the case 3 and the shroud 2 of the cooling fan motor 1 are shown. A heat shield 7 having a cold air passage 5 is installed, and an inlet portion 11 opened toward the cooling fan 9 is formed at one side of the heat shield 7, and an outlet 13 is formed at the other side of the heat shield. By forming a part of the cooling air blown from the cooling fan (9) is introduced into the cold air passage (5) through the inlet portion 11 to cool the cooling fan motor (1) and to be discharged through the outlet (13) Through the air recirculation process to prevent the deterioration of the cooling fan motor (1).

그러나, 이 실시예의 경우 도입부(11)의 단부에 공기도입방향과 동일한 방향으로 절곡된 절곡부(15)에 의해 쿨링팬(9)으로부터 송풍되는 냉각공기의 일부를 포집하여 도입부(11)로 유도하는 역할은 할 수 있지만, 냉각공기의 유입량을 많이 확보하기 어려운 구조적인 한계가 있다. 즉, 상기 절곡부(15)는 냉각공기의 유입방향과 동일한 방향으로 절곡되어 있으므로 냉각공기가 절곡부(15)에 의해 양분되므로써(도 1의 화살표 참조) 히트쉴드(7)로의 냉각공기 도입량이 충분치 않다. 때문에 쿨링팬 모터(1)의 냉각효율이 떨어지게 되는 문제점이 있다.However, in this embodiment, a portion of the cooling air blown from the cooling fan 9 is collected by the bent portion 15 bent in the same direction as the air introduction direction at the end of the inlet portion 11 and guided to the inlet portion 11. It can play a role, but there is a structural limit that is difficult to secure a lot of inflow of cooling air. That is, since the bent portion 15 is bent in the same direction as the inflow direction of the cooling air, the cooling air is introduced into the heat shield 7 by dividing the cooling air by the bent portion 15 (see the arrow in FIG. 1). Not enough Therefore, there is a problem that the cooling efficiency of the cooling fan motor (1) is reduced.

또한, 상기 냉기통로(5)로 유입되는 냉각공기는 쿨링팬 모터(1)의 표면 냉각에 그쳐 실제 발열부인 쿨링팬 모터의 내부 냉각효과가 현저히 떨어져 쿨링팬 모터의 열화방지를 위한 근본적인 해결책이 되지 못하고 있다.In addition, the cooling air flowing into the cold air passage (5) is only cooling the surface of the cooling fan motor (1), and the internal cooling effect of the cooling fan motor, which is the actual heating part, is remarkably lowered, and thus it is not a fundamental solution for preventing the deterioration of the cooling fan motor. I can't.

또한, 도입부(11)의 냉각공기 안내면(12)이 편평한 형상을 가지고 있기 때문에 도입부로 인입되는 냉각공기가 전량 냉기통로(5)로 유입되지 않고 일부는 도입부(11)를 통해 역류 배출되므로써 이후에 도입되는 냉각공기와의 충돌현상으로 와류(A)가 발생하여 소음원이 되고 있다.In addition, since the cooling air guide surface 12 of the introduction portion 11 has a flat shape, the cooling air flowing into the introduction portion is not introduced into the cold air passage 5, and a part of the cooling air is introduced through the introduction portion 11 so as to be discharged later. Vortex A is generated due to the collision with the introduced cooling air and thus becomes a noise source.

따라서, 본 발명의 목적은 쿨링팬으로부터 배출되는 냉각공기를 도입하기 위한 에어 스쿠프를 유선형으로 구성하므로써 냉각공기의 도입량을 배가시킬 수 있는 차량용 쿨링팬 모터의 냉각구조를 제공함에 있다.Accordingly, an object of the present invention is to provide a cooling structure of a vehicle cooling fan motor capable of doubling the amount of introduction of cooling air by forming a streamlined air scoop for introducing cooling air discharged from the cooling fan.

본 발명의 다른 목적은 에어 스쿠프를 통해 도입되는 냉각공기가 쿨링팬으로 집중되도록 하는 차량용 쿨링팬 모터의 냉각구조를 제공함에 있다.Another object of the present invention is to provide a cooling structure of a cooling fan motor for a vehicle such that the cooling air introduced through the air scoop is concentrated in the cooling fan.

본 발명의 또 다른 목적은 쿨링팬 모터측으로 도입되는 냉각공기가 쿨링팬 모터의 내부를 경유토록 하므로써 쿨링팬 모터의 냉각효율을 배가시킬 수 있는 차량용 쿨링팬 모터의 냉각구조를 제공함에 있다.Still another object of the present invention is to provide a cooling structure of a cooling fan motor for a vehicle capable of doubling the cooling efficiency of the cooling fan motor by allowing the cooling air introduced to the cooling fan motor to pass through the inside of the cooling fan motor.

제시된 목적을 달성하기 위한 본 발명의 차량용 쿨링팬 모터의 냉각구조는 쉬라우드의 대략 중앙부에 모터 마운팅에 의해 지지되어 라디에이터 및 컨덴서 등의 열교환기를 냉각시켜주는 쿨링팬 및 쿨링팬 모터를 갖는 팬 쉬라우드 조립체에 있어서; 상기 쿨링팬 모터의 엔드캡 상에 공기유입구와 공기배출구가 각각 형성되고, 상기 쉬라우드에는 엔진열이 쿨링팬 모터로 전도되는 것을 차단하기 위한 히트쉴드가 구비됨과 함께 히트쉴드의 일측에는 쿨링팬으로부터 발생되는 냉각공기의 일부를 상기 공기유입구로 유도하기 위해 유선형의 공기안내면을 갖는 에어스쿠프가 구비된 것을 특징으로 한다.The cooling structure of the vehicular cooling fan motor of the present invention for achieving the proposed object is a fan shroud having a cooling fan and a cooling fan motor which is supported by a motor mounting in the center of the shroud to cool heat exchangers such as radiators and condensers. In an assembly; An air inlet and an air outlet are respectively formed on an end cap of the cooling fan motor, and the shroud is provided with a heat shield for blocking engine heat from being conducted to the cooling fan motor, and on one side of the heat shield from the cooling fan.

또한, 상기 히트쉴드는 그 단부가 모터 마운팅과 결합된 것을 특징으로 한다.In addition, the heat shield is characterized in that the end is coupled to the motor mounting.

또한, 상기 공기유입구에는 공기유입방향으로 루버가 형성되고, 상기 공기배출구에는 공기배출방향으로 경사진 루버가 각각 형성된 것을 특징으로 한다.In addition, the air inlet is characterized in that the louver is formed in the air inlet direction, the air outlet is characterized in that each of the louvers inclined in the air discharge direction is formed.

이하, 본 발명의 바람직한 실시예를 첨부도면을 참조하여 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 일반적인 차량용 쿨링모듈의 구성도로서, 차량에는 에어컨용 컨덴서(30)와 엔진 쿨링용 라디에이터(40)를 냉각시키기 위한 팬 쉬라우드 조립체(50)가 설치되는데, 이들을 통칭 쿨링모듈(cooling module)이라 한다. 특히, 상기 팬 쉬라우드 조립체(50)는 플래넘(plenum)(62)의 대략 중앙부에 스테이터(64)에 의해 지지되는 링형의 모터 마운팅(66)이 위치하는 쉬라우드(60)와, 이 쉬라우드의 모터 마운팅(66)에 고정 지지되는 쿨링팬 모터(68)와, 쿨링팬 모터(68)의 축상에 설치되어 모터 동력에 의해 회전하면서 냉각공기를 차외로부터 흡입하여 상기 컨덴서(30) 및 라디에이터(40)를 향해 토출하므로써 이들을 냉각시키는 쿨링팬(70)등으로 구성된다.2 is a configuration diagram of a general vehicle cooling module, the vehicle is provided with a fan shroud assembly 50 for cooling the air conditioner condenser 30 and the engine cooling radiator 40, these are commonly referred to as a cooling module (cooling module) It is called). In particular, the fan shroud assembly 50 comprises a shroud 60 in which a ring-shaped motor mounting 66 is positioned, which is supported by the stator 64 at the center of the plenum 62. The cooling fan motor 68 fixedly supported by the motor mounting 66 of the wood and the cooling fan motor 68 are installed on the shaft of the cooling fan motor 68 to suck cooling air from the outside of the vehicle while rotating by the motor power, thereby condensing the condenser 30 and the radiator. And a cooling fan 70 or the like that cools them by discharging them toward 40.

이러한 구성으로부터 본 발명의 쿨링팬 모터의 냉각구조는 도 3 및 도 4에서와 같이 엔진열이 쿨링팬 모터(68)로 전도되는 것을 방지하기 위해서 쿨링팬 모터(68)의 엔진측으로 쉬라우드(60)에 결합되는 히트쉴드(80)가 설치된다. 이때, 상기 히트쉴드(80)는 그 단부가 쉬라우드(60)의 모터 마운팅(66)에 나사로서 체결된다.From this configuration, the cooling structure of the cooling fan motor of the present invention has a shroud 60 toward the engine side of the cooling fan motor 68 in order to prevent the engine heat from being conducted to the cooling fan motor 68 as shown in FIGS. 3 and 4. Is coupled to the heat shield 80. At this time, the heat shield 80 has an end thereof fastened as a screw to the motor mounting 66 of the shroud 60.

그리고, 상기 히트쉴드(80)는 그 일측에 쿨링팬(70)으로부터 발생되는 냉각공기의 일부를 후술하는 공기유입구로 유도하기 위해, 히트쉴드(80)로부터 연장되고 쿨링팬(70)을 향해 개방된 그루브(groove)형상의 에어스쿠프(90)가 구비된다. 상기 에어스쿠프(90)는 적어도 공기 안내면(90a)이 유선형으로 되어 쿨링팬(70)으로부터 공급되는 냉각공기를 보다 많이 포집함과 아울러 포집된 냉각공기를 쿨링팬 모터(68)로 원활하게 안내되도록 한다.In addition, the heat shield 80 extends from the heat shield 80 and opens toward the cooling fan 70 to guide a part of the cooling air generated from the cooling fan 70 to an air inlet described later. The grooved air scoop 90 is provided. The air scoop 90 has at least an air guide surface 90a to streamline to collect more cooling air from the cooling fan 70 and to smoothly guide the collected cooling air to the cooling fan motor 68. do.

상기 쿨링팬 모터(68)는 엔진측을 커버링 하고 있는 엔드캡(end cap)(69) 상으로 공기유입구(71)와 공기배출구(73)가 각각 형성되어, 상기 에어스쿠프(90)에 의해 안내되는 냉각공기가 공기유입구(71)로 유도되도록 하므로써 쿨링팬 모터(68)의 실제 발열부인 내부에 냉각공기가 유입되어 냉각효율을 높일 수 있게 된다.The cooling fan motor 68 has an air inlet 71 and an air outlet 73 formed on an end cap 69 covering the engine side, respectively, and is guided by the air scoop 90. By allowing the cooling air to be guided to the air inlet 71, the cooling air is introduced into the inside of the cooling fan motor 68, which is the actual heating part, to increase the cooling efficiency.

상기 공기유입구(69)에는 도 5에서와 같이 공기유입방향으로 경사진 루버(71a)가 형성되고, 공기배출구(73)에는 공기배출방향으로 경사진 루버(73a)가 형성되어 냉각공기의 유입방향과 배출방향을 한정하므로써 냉각공기의 원활한 유입 및 배출을 가능케 한다. 이때, 각 루버(71a,73a)와 엔드캡(69)간의 사이각(θ)은 예각으로 하므로써 냉각공기의 유입방향 내지는 냉각공기의 배출방향과 대략 일치토록 함에 따라 냉각공기의 원활한 입출입이 가능하게 된다.The air inlet 69 is formed with a louver (71a) inclined in the air inlet direction as shown in Figure 5, the air outlet 73 is formed with a louver (73a) inclined in the air discharge direction, the inflow direction of the cooling air By limiting the direction of discharge and the exhaust, it allows the smooth inflow and exhaust of cooling air. At this time, the angle θ between the louvers 71a and 73a and the end cap 69 is an acute angle, so that the inflow and outflow of the cooling air or the discharge direction of the cooling air can be substantially coincided with each other to enable smooth entry and exit of the cooling air. do.

이상의 구성을 갖는 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention having the above configuration is as follows.

쿨링팬 모터(68)의 동력에 의한 쿨링팬(70)의 회전력에 의해 차외로부터 흡입되는 냉각공기의 대부분은 컨덴서(30) 및 라디에이터(40)로 토출되어 이들을 냉각시키고, 이와 함께 컨덴서(30) 및 라디에이터(40)로 향하는 냉각공기의 일부는 히트쉴드(80)의 일측에 형성된 유선형의 에어스쿠프(90)에 의해 쿨링팬 모터(68)의 엔드캡(69) 일측에 형성된 공기유입구(71)로 집중 공급된다. 공기유입구(71)로 유입되는 냉각공기는 쿨링팬 모터(68)의 내부를 경유하면서 쿨링팬 모터의 실질적인 발열부인 내부를 냉각시킨 후 엔드캡(69)의 다른 일측에 형성된 공기배출구(73)를 통해 배출된다. Most of the cooling air sucked from the outside of the vehicle by the rotational force of the cooling fan 70 by the power of the cooling fan motor 68 is discharged to the condenser 30 and the radiator 40 to cool them, together with the condenser 30 And part of the cooling air to the radiator 40 is an air inlet 71 formed on one side of the end cap 69 of the cooling fan motor 68 by a streamlined air scoop 90 formed on one side of the heat shield 80 Is supplied intensively. Cooling air flowing into the air inlet 71 passes through the inside of the cooling fan motor 68 and cools the inside of the cooling fan motor, which is a substantial heating part, and then opens the air outlet 73 formed at the other side of the end cap 69. Is discharged through.                     

이 과정에서, 상기 공기유입구(71)와 공기배출구(73)에 형성된 각각의 루버(71a,73a)에 의해 보다 집중적인 냉각공기의 흐름을 유도할 수 있다. 아울러, 상기 에어스쿠프(90)가 유선형으로 되므로 인해 쿨링팬(70)으로부터 토출되는 냉각공기를 보다 많이 포집하므로써 쿨링팬 모터(68)로의 냉각공기 공급량을 증대시키며, 이미 포집된 냉각공기가 포집 손실없이 전량 쿨링팬 모터(68)로 유도되도록 할 수 있다.In this process, each of the louvers 71a and 73a formed in the air inlet 71 and the air outlet 73 may induce a more concentrated flow of cooling air. In addition, since the air scoop 90 is streamlined, the amount of cooling air discharged from the cooling fan 70 is increased, thereby increasing the amount of cooling air supplied to the cooling fan motor 68, and the trapped loss of cooling air is already collected. It can be made to be guided to the cooling fan motor 68 without the whole amount.

이상의 본 발명은 쿨링팬 모터로 냉각공기를 유도하는 에어스쿠프가 유선형으로 되므로써 냉각공기의 원활한 도입이 가능하며, 쿨링팬으로부터 공급되는 냉각공기를 보다 많이 포집할 수 있고, 포집된 냉각공기가 포집손실없이 쿨링팬 모터로 거의 전량 안내되므로써 냉각효율이 향상된다. 아울러 포집된 냉각공기가 역류되지 않으므로써 유속음의 발생이 없다.According to the present invention, the air scoop for inducing the cooling air to the cooling fan motor is streamlined, so that the cooling air can be introduced smoothly, the cooling air supplied from the cooling fan can be collected more, and the collected cooling air is lost. The cooling efficiency is improved by guiding almost all of the cooling fan motor. In addition, since the collected cooling air is not flowed back, there is no occurrence of flow velocity sound.

또한, 쿨링팬 모터의 엔드캡 상에 공기유입구와 공기배출구가 형성되어 실제 발열부인 쿨링팬 모터의 내부로 냉각공기가 유통되므로써 쿨링팬 모터의 열화를 방지하는 효과도 있다.





In addition, an air inlet and an air outlet are formed on the end cap of the cooling fan motor, and thus cooling air flows into the cooling fan motor, which is the actual heating part, thereby preventing the cooling fan motor from deteriorating.
