Description

차량용 냉각수 가열장치{Vehicle coolant heating device}Vehicle coolant heating device {Vehicle coolant heating device}

본 발명은 차량용 냉각수 가열장치에 관한 것으로, 더욱 상세하게는, 차량용 냉각수 가열장치로 유입되는 냉각수를 적정수위 및 적정온도로 유지하여 발열체가 과열되어 화재나 폭발하는 것을 방지할 수 있는 차량용 냉각수 가열장치에 관한 것이다.The present invention relates to a vehicle coolant heating device, and more particularly, to a vehicle coolant heating device capable of preventing fire or explosion due to overheating of a heating element by maintaining coolant flowing into the vehicle coolant heating device at an appropriate level and temperature. It is about.

내연기관 차량은 엔진에서 발생하는 폐열을 냉각수를 통해 회수하여 부품예열과 승객석 난방을 하지만, 폐열이 충분하지 않는 전기구동차량의 경우에는 전기 가열장치로 냉각수를 가열하여 배터리, 모터, 인버터 등의 전장품을 예열하거나 승객석 난방을 실시한다.In an internal combustion engine vehicle, waste heat generated from the engine is recovered through coolant to preheat parts and heat the passenger seat. However, in the case of an electric drive vehicle where waste heat is not sufficient, the coolant is heated with an electric heating device to heat electric components such as batteries, motors, and inverters. or heat the passenger seat.

차량용 냉각수 가열장치는 냉각수의 적정 수위와 적정 온도를 항상 유지해야 하는데, 적장한 수위와 온도를 유지하지 못하는 경우에는 과열로 인해 냉각수 가열장치의 소손이나 화재 및 폭발의 위험이 있다.Vehicle coolant heating devices must always maintain an appropriate level and temperature of the coolant. If the appropriate level and temperature are not maintained, there is a risk of burnout, fire, or explosion of the coolant heating device due to overheating.

종래의 냉각수 가열장치는 과열로부터의 안전을 위해 가열된 냉각수와 접촉하고 있는 부품으로부터 열전달된 온도를 감지하는 과열방지장치에 의해 전력을 차단하는 방식을 적용하고 있으나, 이와 같은 방식은 비열이 높은 냉각수로부터 간접적으로 열전달되어 과열방지장치가 작동하기 때문에 냉각수 가열장치의 발열체가 소손되기 전에 전력을 차단하기 어려운 문제점이 있다.For safety from overheating, a conventional cooling water heating device uses a method of cutting off power by an overheat protection device that senses the temperature transferred from a part in contact with the heated cooling water. Since the overheat protection device is operated by indirect heat transfer from the cooling water heating device, it is difficult to cut off power before the heating element of the cooling water heating device is burned.
