The invention discloses an exhaust waste heat recycling system and a control method thereof.The system comprises a cooling liquid filling box used for providing cooling liquid; the exhaust tail pipe water jacket is annularly arranged at the tail end of an exhaust tail pipe of the vehicle in a sleeving mode, communicates with the cooling liquid filling box and is used for obtaining exhaust energy from the exhaust tail pipe so as to heat the cooling liquid; the input end of the circulating pump is communicated with the exhaust tail pipe water jacket, the first output end of the circulating pump is communicated with a heat exchanger of the fuel tank through a first circulating pipeline, and the second output end of the circulating pump is communicated with a warm air core of a cab through a second circulating pipeline and used for providing circulating power for the cooling liquid; the controller is electrically connected with the circulating pump and used for obtaining a current state signal of the vehicle and controlling starting and stopping of the circulating pump and connection and disconnection of the first circulating pipeline and/or the second circulating pipeline according to the current state signal of the vehicle so as to determine whether heat can be provided for the fuel tank and/or the cab or not. By means of the system, the fuel tank and/or the cab are/is heated through exhaust waste heat.
本发明公开了一种排气余热回收利用系统及其控制方法,系统包括冷却液加注箱,用于提供冷却液;排气尾管水套,环套于车辆的排气尾管末端,且与冷却液加注箱连通,用于从排气尾管处获取排气能量,以对冷却液进行加热;循环泵,输入端与排气尾管水套连通,第一输出端通过第一循环管路与燃油箱的热交换器连通,第二输出端通过第二循环管路与驾驶室的暖风芯体连通,用于为冷却液提供循环动力;控制器,控制器与循环泵电连接,用于获取车辆当前状态信号,并根据车辆当前状态信号,控制循环泵的启停,以及第一循环管路和/或第二循环管路的通断,以确定是否对燃油箱和/或驾驶室提供热量。通过上述系统,利用排气余热实现对燃油箱加热和/或驾驶室供暖。
