Technical Field
[0001] The utility model belongs to the technical field of passenger car heating, and in particular relates to an integrated defrosting and heating system in a fuel passenger car. Background Art
[0002] Fuel-powered buses generally use air heating to heat the interior of the vehicle. This method uses the vehicle engine to drive the heater to heat the exhaust gas from the engine and pass it into the cab and passenger compartment. When the vehicle is driving, the exhaust gas from the engine will be heated by the heater and then sent into the vehicle through the air duct. Air heating has the following disadvantages:
[0003] 1. This heating method is prone to carbon dioxide poisoning and other situations, so it is necessary to ensure air circulation in the car;
[0004] 2. The bus space is too large and the temperature in the cabin rises slowly;
[0005] 3. During the stay of the vehicle, the driver and passengers need to keep the engine running for heating, which wastes fuel. Utility Model Content
[0006] In order to solve the above problems, the utility model provides an integrated defrosting and heating system for a fuel-powered passenger car.
[0007] The technical solution adopted by the utility model is an integrated defrosting and heating system in a fuel bus, comprising an engine, an electric injection heater and a water pump, wherein the coolant output end of the engine is connected to the radiator through a pipeline and then to the electric injection heater, the outlet of the electric injection heater is connected to an electric water valve through a pipeline, the two water outlet ends of the electric water valve are respectively connected to the pipelines at the engine coolant output end and input end through pipelines, and the water pump is installed on the pipeline.
[0008] Preferably, a plurality of radiators are respectively arranged at the front, middle and rear of the vehicle cabin for uniform heating, and a cooling fan is installed in front of the radiator, and the cooling fan is connected to a controller.
[0009] Preferably, the pipe connected to the radiator is also connected to a defroster.
[0010] Preferably, temperature sensors are provided at the front, middle and rear parts of the vehicle cabin, and the temperature sensors are connected to the controller.
[0011] Compared with the prior art, the beneficial effects of the utility model are that it integrates engine residual heat heating and electronic injection heating to heat the coolant, combines defrosting and heating functions, realizes fast and efficient in-vehicle environment adjustment, and can achieve precise temperature control, improving passenger comfort and safety, which is mainly reflected in the following aspects:
[0012] 1. When the engine is cold started in winter, it can quickly preheat the engine and reduce fuel consumption;
[0013] 2. It can prevent nitrogen dioxide from entering the car and avoid nitrogen dioxide poisoning for the driver;
[0014] 3. When the vehicle is parked, the engine is turned off and the electric injection heater is used to heat the vehicle to maintain a constant temperature and reduce the fuel consumption of the vehicle;
[0015] 4. When the vehicle is driving, the residual heat of the engine can be used to heat the coolant to maximize the energy generated by the engine. BRIEF DESCRIPTION OF THE DRAWINGS
