Description

New energy automobile engine preheats water heating heater Technical Field The utility model relates to the technical field of new energy automobile heating devices, in particular to a water heating heater for preheating an engine of a new energy automobile. Background In winter in many northern areas of China, the problem of difficult cold start of an automobile engine exists. When the external environment temperature is too low, the engine body temperature and the engine oil temperature are also low, and particularly, the phenomenon of increased viscosity of the engine oil caused by too low temperature occurs. In this case, if the cold start is forced, wear of moving parts at the time of the cold start of the engine is increased due to a low lubricating ability of the engine oil. In addition, since the engine temperature is too low, incomplete combustion of fuel gas in each cylinder is caused during cold start of the engine, so that fuel consumption of an automobile is increased, and generated exhaust gas is increased, harmful substances in the exhaust gas are also increased, and therefore, a water heating heater is required to preheat the engine. As in chinese patent CN111997809a, a water heating type warming device for cold starting of an automobile engine is disclosed, but the existing water heating type heater is only suitable for preheating the automobile engine and is not suitable for the working condition of long-time running of a new energy automobile. Therefore, the utility model provides a water heating heater for preheating a new energy automobile engine, which is used for solving the problems. Disclosure of utility model The utility model aims to provide a water heating heater for preheating an engine of a new energy automobile, which aims to solve the problems in the background technology.
