Description

Technical Field

[0001] The present invention belongs to the technical field of new energy vehicles, and in particular is a diesel and AC / DC electric driven hybrid heater for a vehicle. Background Art

[0002] Patent publication number CN217705430U discloses an electric fuel injection heater, belonging to the field of fuel heaters. It includes: a burner and a heat exchanger, with the burner including an aluminum bracket, a motor, an oil pump, an oil injector, an ignition device, and a combustion chamber. The solution retains the existing technology and functions of the prior art, only the air inlet of the air regulating hood and the air duct within the air inlet shield are arranged at a 180° angle, with the oil inlet and outlet pipes respectively arranged on either side of the heat exchanger; the ignition device is fixedly installed in the air inlet shield; a control box is installed in the aluminum bracket, which is integrated with the aluminum bracket and contains a controller. The present invention solves the problem of dust entering the product and causing carbon deposits by setting the air inlet and air duct at a 180-degree angle; the oil inlet and outlet are arranged on both sides of the heat exchanger, solving the problem of the oil inlet pipe being drawn out from one side, making it difficult to distinguish between the inlet and return oil.

[0003] Existing heaters are generally diesel heaters, DC heaters, or AC heaters. Diesel heaters have the problems of high fuel consumption and high operating costs during actual use. DC heaters must use the power of the electric vehicle during actual use, which greatly affects the range of the electric vehicle in low winter temperatures. AC heaters must use AC power during use because the battery needs to be preheated before charging to raise the battery temperature to the appropriate temperature. If a DC system is used, AC needs to be converted to DC, and then the electricity is charged to the battery, which then heats the DC heater. The energy utilization rate is not high and affects the battery's charge and discharge life. Therefore, the AC system directly uses AC power, which will have a higher energy utilization rate. The disadvantage is that the AC power can only be used when the vehicle is parked for charging and cannot be used while driving. In actual use, the three sets of heaters are not provided with corresponding adapter connection mechanisms, resulting in the three sets of heaters not being able to be combined into a mixed heater to improve the overall mixed heating effect.
