Abstract

The invention provides a heating device which comprises a shell (1) and a heat sink (2). The shell (1) is provided with a liquid inlet (3) and a liquid outlet (4), the heat sink (2) comprises a heat dissipation pipe (5) which is located inside the shell (1), and the heat dissipation pipe (5) is provided with an air inlet end (22) and an air outlet end (23). In addition, the invention further provides an automobile comprising the heating device. The heating device can utilize residual heat of automobile exhaust to heat urea solution inside a treatment device after exhausting, electric energy and oil consumption of the whole automobile can be saved, resources of exhaust gas can be effectively utilized, and the purposes of energy conservation, environmental protection, and urea congelation prevention or urea thawing time shortening in low temperature are achieved.

Description

technical field [0001] The invention relates to a heating device and a motor vehicle comprising the heating device. Background technique [0002] At present, the exhaust purification system of commercial diesel vehicles adopts SCR system to meet the increasingly stringent emission regulations. The SCR system needs to use 32.5% urea aqueous solution that meets the international standard ISO22241-1. The urea aqueous solution will freeze below -11.5°C. In order to prevent low-temperature urea from freezing, the SCR system generally uses electric heaters or engine coolant to heat the urea solution in the urea tank, urea pipeline and urea nozzle. If the electric heater is used for heating, since the electric heater is powered by the battery of the whole vehicle, the electric energy of the vehicle will be lost, and the power supply capacity of the battery is required to be very high. If the engine coolant is directly used for heating, it will increase the heat dissipation burden ...
