The invention discloses an engine water circulation-based heating system in a coach for improving heat preservation effects of a heating pipe and a reflux pipe, and improving the sealing performance of a floor. The system comprises a defroster, at least one heater, a heating pipe and a reflux pipe, wherein both of the heating pipe and the reflux pipe comprise main body sections, connection sections which are in water circulation connection with the engine at two ends of the main body sections, and communication sections which are connected with the defroster; circular pumps are arranged on the connection sections of the heating pipe in series; the heater is arranged below chairs at the inside of front and back passages in the carriage; the heater structurally comprises a casing; and a radiator, an air supply fan, an inlet pipe and an outlet pipe are arranged in the casing, wherein one ends of the inlet pipe and the outlet pipe are connected with the radiator, and the other ends of the inlet pipe and the outlet pipe are connected to the main body sections on the heating pipe in series or connected to the main body sections on the heating pipe and the reflux pipe in parallel. The heating system is excellent in heat preservation effect, and is particularly applied to northeast and other cold areas in China.
Description
technical field [0001] The invention relates to a heating system in a passenger car, in particular to a heating system in a passenger car based on engine water circulation. Background technique [0002] With the continuous development of society, people have higher and higher requirements for the comfort of passenger cars. The heating system of passenger cars has become one of the main functional facilities, and the heating system of passenger cars is particularly important in the cold regions of Northeast China. At present, the mainstream heating system used in passenger cars is the heating system based on engine water circulation, and its specific structure includes: two to three heating devices mainly composed of radiators and air supply fans matched with The hose is connected to the water inlet and outlet of the engine water cycle and the heating water pipe and the return water pipe. The connecting hose, the heating water pipe and the return water pipe are all made of ru...
