Passenger car heat generating device and control system thereof

Abstract

The invention discloses a passenger car heat generating device and a control system thereof. The passenger car heat generating device comprises a heat box, a heat exchange box and a secondary heating box, wherein the heat box has a horizontal tank-shaped heat-insulation box structure; an air inlet and an air outlet are formed in the heat box and respectively communicate with a passenger car exhaust tube; the heat exchange box is welded to the inside of the heat box in a sealed manner; a plurality of heat exchange plates are successively welded to the inside of the heat exchange box in the longitudinal direction; a fan is further arranged on one side, which is positioned on the heat exchange box, in the heat box; a first solenoid valve and a second solenoid valve are respectively mounted at the left end and the right end of the heat box; and an electric heating device is arranged in the secondary heating box and is connected with a power controller through an external wire. Heat is produced in a mode of heat exchange by using waste gas of a passenger car, most of heat in the waste gas is recycled, heat emission is reduced, meanwhile, the heating purpose is achieved, energy consumption and emission of the passenger car are reduced, and energy conservation and heating are realized.

Description

technical field [0001] The invention relates to the technical field related to passenger cars, in particular to a heating generating device for passenger cars and a control system thereof. Background technique [0002] The winter in northern my country is cold, and the windshield defrosting and the heating device in the car play an important role in the operation of passenger cars in winter. Passenger cars often use oil heating for heating, which relies on the combustion of oil by the burner to obtain heat energy, and increases the ambient temperature in the compartment through two heat transfer methods: first, the burner burns oil to obtain heat, and uses this heat to reheat the engine to cool The temperature of the water is sent to the heat dissipation water tank for heat dissipation, and the temperature of the engine return water can be between 40-50°C; second, the burner burns oil to obtain heat energy, which directly heats the surrounding air and increases the ambient t...

AI Technical Summary

Problems solved by technology

[0003] In the two types of oil heating systems, the advantage is that the heating efficiency is improved and a good heating effect is guaranteed; the disadvantage is that a large amount of energy is consumed while obtaining heat energy, resulting in a huge operating cost, and at the same time, in the process of burning and discharging produce environmental pollution

At the same time, when the passenger car engine is running, a considerable part of the energy generated by fuel combustion is lost in the form of heat energy, and the temperature at the exhaust port of some engines can reach above 800°C, which is a serious waste of energy.
