Detailed Description
In order to make the objects, contents and advantages of the present invention clearer, the following detailed description of the embodiments of the present invention is provided.
The utility model provides an oil-electricity mixed liquid heating integrated device which mainly comprises a liquid heater 1, a PTC electric heater 2, an engine water jacket 3, a heater bracket 4, an oil taking pump 5, an oil taking device 6, a protective cover 7 and an air-conditioning fan heater 8, wherein the liquid heater 1 and the PTC electric heater 2 are integrally fixed in the protective cover 7, are fixed on the outer side of a frame longitudinal beam through the heater bracket 4 and are positioned on the front side of an oil tank, the oil taking pump 5 is fixed on the inner side of the longitudinal beam, the oil taking device 6 is installed in the oil tank, the engine water jacket 3 is fixed in an engine, the liquid heater 1 and the PTC electric heater 2 are connected in parallel, and the oil taking pump 5 takes oil through the oil taking device.
One path of water outlets of the liquid heater 1 and the PTC electric heater 2 is connected with a water inlet of the air-conditioning warm air blower 8, and the other path of water outlets is converged with a water outlet of the air-conditioning warm air blower 8 and then flows into a water inlet of the engine water jacket 3; the water outlet of the engine water jacket 3 is connected with the water inlets of the liquid heater 1 and the PTC electric heater 2 through the water separator.
The water distributors of the liquid heater 1 and the PTC electric heater 2 are connected with an engine water jacket 3 through water pipes, cooling liquid flows through the water pipes, oil in the oil tank is supplied to the liquid heater through an oil taking pump, and the oil is ignited to be used for heating the cooling liquid in the liquid heater;
the cab change-over switch supplies power to the PTC electric heater 2, and the electric energy is converted into heat energy to heat the cooling liquid in the PTC electric heater.
When the fuel heater works, the cab change-over switch is used, the relay contact is disconnected, the connection between the PTC heating controller and the water pump is cut off, the fuel heater controller and the water pump are connected, the fuel heater controller controls the water pump to work, and the fuel heating works to heat the engine coolant.
