Description

충전기에 배치된 내장 온도 센서를 통한 냉각수 온도의 센싱 구조{Sensing structure of coolant temperature via built-in temperature sensor placed in charger}Sensing structure of coolant temperature via built-in temperature sensor placed in charger}

본 발명은 외부 온도센서를 사용하지 않은 상태에서 회로 기판에 실장된 내부온도센서를 통해 전기 차량용 배터리에 대한 충전기의 냉각을 수행하는 냉각수의 온도를 센싱하는 구조에 관한 것이다.The present invention relates to a structure for sensing the temperature of a coolant that cools a charger for an electric vehicle battery through an internal temperature sensor mounted on a circuit board without using an external temperature sensor.

최근 환경 규제가 강화되면서 하이브리드차(HEV), 플러그인 하이브리드차(PHEV), 배터리 전기차(BEV) 등 친환경차들이 주목받고 있다. 특히, 순수하게 전기에너지만을 사용하는 BEV와 배터리 에너지와 엔진을 동시에 사용하며 외부에서 배터리 충전이 가능한 PHEV 성장세가 두드러진다.As environmental regulations have recently been strengthened, eco-friendly vehicles such as hybrid vehicles (HEV), plug-in hybrid vehicles (PHEV), and battery electric vehicles (BEV) have attracted attention. In particular, the growth of PHEV, which uses only BEV, which uses purely electric energy, and battery energy and engine at the same time, and which can be charged externally, is remarkable.

배터리 전기차와 플러그인 하이브리드차는 배터리 충전을 위한 충전기가 필요하다. 배터리 충전기는 충전시간에 따라 완속, 급속, ICCB으로 구분되고 위치에 따라 탑재형(On-Board) 또는 외장형(Off-Board)으로 구분된다.Battery electric vehicles and plug-in hybrid vehicles require a charger to charge the battery. Battery chargers are classified into slow, rapid, and ICCB according to the charging time, and classified into on-board or off-board depending on the location.

완속 충전기와 급속 충전기는 별도로 설치된 220V나 380V용 전원을 이용해 충전하는 방식이고, ICCB는 가정에서 충전 가능한 케이블이다. 완속 충전 시에는 차량 내에 별도로 설치된 충전기(OBC)를 거쳐서 고전압 배터리가 충전된다.The slow charger and the quick charger are charged using 220V or 380V power separately installed, and the ICCB is a cable that can be charged at home. In slow charging, the high voltage battery is charged through a separately installed charger (OBC) in the vehicle.

급속충전방식은 충전시간이 짧은 장점에도 불구하고 충전소가 필수적이라는 단점이 있다. 현재 국내에는 전국 한전 사업소, 공공 주차장, 대형마트, 공동 주택 등에 충전소가 구축돼 있지만 넉넉하다고는 할 수 없다. 따라서, 모든 BEV와 PHEV는 가정용 전원플러그가 있는 곳 어디에서든지 충전이 가능하도록 탑재형 충전기(OBC)를 갖추고 있다.The rapid charging method has a disadvantage in that a charging station is essential despite the short charging time. Currently, charging stations are installed in Korea's KEPCO offices, public parking lots, large marts, and apartment houses, but this is not enough. Therefore, all BEVs and PHEVs are equipped with a built-in charger (OBC) that allows charging anywhere in the home power plug.

친환경용 탑재형 충전기인 OBC(On Board Charger)는 차량 주차 상태에서 AC 110V/220V 전원으로 차량의 고전압 배터리를 완속으로 충전하는 차량 탑재형 충전기이다. BMS와 협조제어를 통해 배터리 충전 방식(정전류, 정전압)을 내부적으로 제어하고 있다.The eco-friendly on-board charger (OBC) is a vehicle-mounted charger that slowly charges the vehicle's high-voltage battery with AC 110V / 220V power while the vehicle is parked. The battery charging method (constant current, constant voltage) is controlled internally through cooperative control with the BMS.

OBC는 상용 전원인 교류를 직류로 변환하여 차량 내부 배터리를 충전하는 기능을 한다. OBC는 일반적으로 입력 전원인 AC 전원의 노이즈를 제거하는 입력필터, 에너지 효율을 높여주는 PFC(Power Factor Corrector) 회로, 배터리에 전력을 안정적으로 공급하기 위한 DC/DC 컨버터, 충전소 및 차량 내부의 다른 장치와 통신하며 OBC를 제어하는 제어회로 등으로 구성된다.OBC converts AC, which is a commercial power source, into DC to charge the battery inside the vehicle. OBC is an input filter that removes noise from AC power, which is generally an input power source, a PFC (Power Factor Corrector) circuit that increases energy efficiency, a DC / DC converter for stably supplying power to batteries, charging stations, and other inside the vehicle. It consists of a control circuit that communicates with the device and controls the OBC.

OBC는 충전시에 발열되고, 이러한 발열은 전력변환부품들의 성능 및 수명에 악영향을 미치므로 냉각시스템을 구비하여 발열을 해소해야 한다.OBC generates heat during charging, and such heat generation adversely affects the performance and lifespan of the power conversion components, so a cooling system must be provided to solve the heat generation.

냉각시스템을 이용하여 차량을 구성하는 전력변환부품들 중 OBC를 냉각하는 과정을 보면, OBC를 구성하는 회로기판에 집적된 전자소자들의 냉각을 위해 상기 회로기판에 연결된 금속 플레이트 상에 냉각수를 유동하게 함으로써 냉각 기능을 수행한다. Looking at the process of cooling the OBC among the power conversion components constituting the vehicle using the cooling system, the cooling water flows on a metal plate connected to the circuit board for cooling of electronic devices integrated in the circuit board constituting the OBC. Thereby performing the cooling function.

기존에는 금속 플레이트에 유동하는 냉각수의 적정 온도 확인을 위하여 외장형 온도 센서를 사용하였는데, 이 경우에 금속 플레이트를 관통 설치하여 냉각수를 직접 센싱하는 외장형 온도 센서의 구조로 인하여 냉각수의 리크가 발생할 수 있고, 외장형 온도센서의 가격이 비싸므로 설계 단가가 올라간다는 문제점이 있다.Previously, an external temperature sensor was used to check the proper temperature of the cooling water flowing in the metal plate. In this case, leakage of the cooling water may occur due to the structure of the external temperature sensor that directly senses the cooling water by installing the metal plate through. Since the price of the external temperature sensor is expensive, there is a problem that the design cost increases.

본 발명의 목적은 종래의 외장형 온도 센서 사용의 문제점을 해결하고자, 외부 온도센서를 사용하지 않은 상태에서 회로 기판에 실장된 내부온도센서를 통해 전기 차량용 배터리에 대한 충전기의 냉각을 수행하는 냉각수의 온도를 센싱하는 구조를 제공하는 것을 특징으로 한다.An object of the present invention is to solve the problem of using a conventional external temperature sensor, the temperature of the cooling water to perform the cooling of the charger for the battery for the electric vehicle through the internal temperature sensor mounted on the circuit board without using an external temperature sensor It characterized in that it provides a structure for sensing the.

상기와 같은 목적을 달성하기 위한 본 발명에 따라 전기 차량용 배터리에 대한 충전기의 냉각을 수행하는 냉각수의 온도를 센싱하는 구조는 냉각수의 유동을 위한 냉각수 유로가 형성된 유로 하우징(10); 상기 유로 하우징(10) 상에 이격 배치된 상태에서 복수의 전자소자가 집적 형성되는 회로 기판(20); 상기 회로 기판(20) 상에 집적된 상태에서 유로 하우징(10)의 표면 상에 밀착하여 온도를 측정하는 내장 온도센서(30); 및 상기 회로 기판(20)을 관통한 상태에서 상기 유로 하우징(10) 상에 고정 결합하는 결속 수단(40);을 포함하고, 상기 회로 기판(20)에 실장된 내장 온도센서(30)를 통해 전기 차량용 배터리에 대한 충전기의 냉각을 수행하는 냉각수의 온도를 센싱함으로써 외장 온도센서의 사용 필요성을 제거하는 것을 특징으로 한다.According to the present invention for achieving the above object, the structure for sensing the temperature of the coolant for cooling the charger for the battery for an electric vehicle includes a flow path housing 10 in which a coolant flow path for cooling water flow is formed; A circuit board 20 in which a plurality of electronic devices are integrally formed while being spaced apart from the flow path housing 10; A built-in temperature sensor 30 for measuring the temperature in close contact with the surface of the flow path housing 10 in an integrated state on the circuit board 20; And a binding means 40 fixedly coupled on the flow path housing 10 in a state that penetrates the circuit board 20, and includes a built-in temperature sensor 30 mounted on the circuit board 20. It is characterized in that it eliminates the need to use an external temperature sensor by sensing the temperature of the coolant that performs cooling of the charger for the battery for the electric vehicle.

본 발명은 전기 차량용 배터리에 대한 충전기를 구성하는 회로 기판에 실장된 내부온도센서를 통해 회로 기판에 인접한 냉각 플레이트를 유동하는 냉각수의 온도를 센싱하는 구조를 통해 비용적인 장점을 갖게 한다.The present invention has a cost advantage through a structure for sensing the temperature of the coolant flowing through the cooling plate adjacent to the circuit board through an internal temperature sensor mounted on the circuit board constituting the charger for the battery for the electric vehicle.

이하, 도면을 참조하여 본 발명에 따른 실시예의 구성 및 작용을 상세히 설명한다.Hereinafter, the configuration and operation of the embodiment according to the present invention will be described in detail with reference to the drawings.

본 명세서 상에서는 탑재형 배터리 충전기인 OBC 상에 적용되는 냉각수의 온도 센싱 구조를 중심으로 설명하지만, 이에 한정되는 아니고 냉각수를 가열하는 형태의 냉각수 가열식 히터 또는 냉각수 히터의 수온을 측정하는 용도로도 응용이 가능하다.In the present specification, the temperature sensing structure of the cooling water applied on the OBC, which is an on-board battery charger, is mainly described, but the present invention is not limited thereto. It is possible.

도 1 내지 도 3을 참조하면, 본 발명에 따라 냉각수의 온도 센싱 구조가 채용된 충전기는, 냉각수의 유동을 위한 냉각수 유로가 형성된 유로 하우징(10), 유로 하우징(10) 상에 이격 배치된 상태에서 복수의 전자소자가 집적 형성되는 회로 기판(20), 회로 기판(20) 상에 집적된 상태에서 유로 하우징(10)의 표면 상에 밀착하여 온도를 측정하는 내장 온도센서(30), 회로 기판(20)을 관통한 상태에서 유로 하우징(10) 상에 고정 결합하는 결속 수단(40) 및 유로 하우징(10)의 일측면을 덮도록 구비되어져 상기 회로 기판(20)과 내장 온도센서(30) 등을 그 내부에 수용하는 구조를 갖는 외부 커버(50)를 포함한다.1 to 3, a charger employing a cooling water temperature sensing structure according to the present invention is spaced apart on a flow path housing 10 and a flow path housing 10 in which cooling water flow paths for cooling water flow are formed. A circuit board 20 in which a plurality of electronic devices are integratedly formed, a built-in temperature sensor 30 in close contact with the surface of the flow path housing 10 in an integrated state on the circuit board 20, and a circuit board It is provided so as to cover one side of the binding means 40 and the flow path housing 10 fixedly coupled to the flow path housing 10 in the state penetrated through the circuit board 20 and the built-in temperature sensor 30 It includes an outer cover 50 having a structure for receiving the back therein.

유로 하우징(10) 내에 형성된 냉각수 유로(12)는 상기 유로 하우징(10)의 일측을 통해 유입구가 형성되고, 타측을 통해 배출구가 형성되는 구조일 수 있다. The cooling water channel 12 formed in the channel housing 10 may have a structure in which an inlet port is formed through one side of the channel housing 10 and an outlet port is formed through the other side.

냉각수 유로(12)의 구조에 대해 구체적으로 설명하면, 유입구에서 상부 방향으로 소정각도 경사지게 형성된 상태로 이루어진 진입 영역(13), 진입 영역(13)에서 이어지는 것과 동시에 내장 온도센서(30)의 하부 상에 배치되는 공간인 수온 측정 챔버(14), 수온 측정 챔버(14)에서 배출구까지 이어지는 영역인 연속 유동 영역(15)을 포함한다.When the structure of the cooling water flow path 12 is described in detail, it is connected to the entry area 13 and the entrance area 13, which are formed to be inclined at a predetermined angle from the inlet to the upper direction, and at the same time, the lower phase of the built-in temperature sensor 30 It includes a water temperature measuring chamber 14, which is a space disposed in, and a continuous flow zone 15, which is an area extending from the water temperature measuring chamber 14 to the outlet.

수온 측정 챔버(14)는 진입 영역(13)과 연속 유동 영역(15)의 상부단과 비교해서 상대적으로 더 상부 방향으로 돌출된 상태의 여유 공간(14a)을 확보한다. 즉, 진입 영역(13)을 통해 유동된 냉각수가 상대적으로 단위 유량이 큰 상태를 갖는 수온 측정 챔버(14)로 유입되어짐으로써 냉각수의 일시적인 정체 및 와류 발생을 유발하게 된다. 이를 통해서 유입된 냉각수는 수온 측정 챔버(14) 상에서 충분한 열적 교류를 유발할 수 있게 한다. 한편, 여유 공간(14a) 상에서 진입 영역(13)과 연속 유동 영역(15)과 맞닿는 부분의 경사각을 상이하게 설정할 수 있다. 구체적으로는, 진입 영역(13)과 연결되는 제1 경사각(d1)을 연속 유동 영역(15)과 연결되는 제2 경사각(d2)에 비해 더 완만하게 설정한다. 제1 경사각(d1)과 제2 경사각(d2) 사이는 상부 방향으로 소정의 양의 기울기를 갖는 제3 경사각(d3)을 설정한다. 이를 통해 수온 측정 챔버(14)의 여유 공간으로 진입되는 냉각수는 상기 제1 경사각(d1)을 통해 완만한 흐름으로 유입을 진행한 상태에서 제3 경사각(d3)을 갖는 중심 영역을 거치면서 확대된 공간 상에서 유입 냉각수의 확산 내지 분산을 가능하게 하고, 하부 방향으로 급격하게 기울어지는 제2 경사각(d2)을 갖는 공간 상에서 유입된 냉각수의 조밀화를 가능하게 한다.The water temperature measuring chamber 14 secures the free space 14a in a state protruding in a relatively higher direction compared to the upper ends of the entry area 13 and the continuous flow area 15. That is, the cooling water flowing through the entry area 13 is introduced into the water temperature measurement chamber 14 having a relatively large unit flow rate, thereby causing temporary stagnation and vortex generation of the cooling water. The coolant introduced through this allows sufficient thermal exchange on the water temperature measurement chamber 14. On the other hand, the inclination angle of the portion in contact with the entry region 13 and the continuous flow region 15 on the free space 14a can be set differently. Specifically, the first inclination angle d1 connected to the entry area 13 is set more gently than the second inclination angle d2 connected to the continuous flow area 15. Between the first inclination angle d1 and the second inclination angle d2, a third inclination angle d3 having a predetermined positive inclination in the upper direction is set. Through this, the cooling water entering the free space of the water temperature measuring chamber 14 is enlarged while passing through the central region having the third inclination angle d3 while flowing in a gentle flow through the first inclination angle d1. Diffusion or dispersion of the inflow cooling water in the space is possible, and densification of the inflow cooling water in the space having a second inclination angle d2 rapidly inclined in the downward direction is possible.

수온 측정 챔버(14) 상에는 상하부를 연결하는 형태의 리브들이 다양하게 설치된다. 리브들은 냉각수 유로(12)의 형상을 유지하는 기능을 하는 것과 동시에 유입된 냉각수의 유동 경로를 다양하게 설정하는 것을 가능하게 한다.Various ribs are provided on the water temperature measuring chamber 14 to connect the upper and lower parts. The ribs function to maintain the shape of the cooling water flow path 12 and at the same time, it is possible to set various flow paths of the introduced cooling water.

내장 온도센서(30)의 일 실시예로서는 NTC 서미스터(negative temperature coefficient thermistor)를 채용한다.As an embodiment of the built-in temperature sensor 30, an NTC thermistor (negative temperature coefficient thermistor) is employed.

서미스터는 반도체의 전기저항이 온도에 따라 크게 변하는 것을 이용한 전자부품을 총칭하는 것일 수 있는데, 특히 온도에 대하여 안정적이고 온도 특성의 재현성이 좋은 것을 서미스터 온도센서로써 사용한다. NTC 서미스터는 부(負)의 온도계수를 가지고 연속적으로 전기저항이 변화하는 서미스터로서 NTC로 약칭한다. 주로 금속산화물 반도체에 의하여 제조되지만 유기물계, Si 단결정계, SiC 계의 것도 있고, 모두 온도 센서로써 사용된다.The thermistor may be a general term for an electronic component using a semiconductor whose electrical resistance varies greatly with temperature. In particular, a thermistor temperature sensor that is stable with respect to temperature and has good reproducibility of temperature characteristics is used. NTC thermistor is a thermistor that has a negative temperature coefficient and continuously changes its electrical resistance.
