The invention provides an auxiliary thermal management heater for a new energy vehicle and a thermal protection method. The auxiliary heat management heater of the new energy vehicle includes: a controller; the oil pump is used for pumping oil to the combustion chamber to supply heat through combustion; the chopping control circuit is connected with the controller and the oil pump and is used for adjusting the oil pumping quantity of the oil pump to the combustion chamber under the control of the controller; one end of the temperature switch is connected with a power source of the oil pump, the other end of the temperature switch is connected with the oil pump, and the temperature switch is used for disconnecting the power source and the oil pump when the temperature of the combustion chamber exceeds a preset value. According to the auxiliary thermal management heater of the new energy vehicle and the thermal protection method, the power supply of the oil pump is connected with the oil pump through the temperature switch, so that when the temperature of the combustion chamber is too high, the power supply of the oil pump can be cut off in time, the oil pump stops supplying oil to the combustion chamber, and uncontrollable combustion caused by too high temperature of the combustion chamber can be prevented; and the safety performance of the heater is effectively improved.
本申请提供了一种新能源车辆的辅助热管理加热器和热保护方法。新能源车辆的辅助热管理加热器包括:控制器;油泵,用于向燃烧室泵油以通过燃烧供热;斩波控制电路,连接所述控制器和所述油泵,用于在所述控制器的控制下,调节所述油泵向所述燃烧室泵油量;温度开关,一端连接所述油泵的电源,另外一端连接所述油泵,用于在所述燃烧室的温度超过预设值时断开所述电源和所述油泵。上述的新能源车辆的辅助热管理加热器和热保护方法将油泵的电源通过温度开关连接油泵,使得在燃烧室的温度过高时,可以及时切断油泵的电源,油泵得以停止向燃烧室供油,从而可以防止燃烧室的温度过高而引起不可控燃烧,有效提高了加热器的安全性能。
