Water heating type warm-air device for intelligent automobile

Abstract

A smart vehicle water heated warm air unit includes: an exhaust heater, a sensor, a controller, an air actuator, a water way bypass actuator, a water pump, a forced radiator and a defroster. The exhaust heater is mounted on the discharging pipelines of a motor, and connected with a motor cooling system via a water pipe; the water pump is arranged between the motor and the exhaust heater; the water inlet end of the water pump is connected with a water shelve of the motor via water pipes, and a water outlet end is connected with the water inlet end of the exhaust heater via water pipes; an air and a water way bypass actuators which are arranged at an air inlet and the water outlet of the exhaust heater independently are connected with an air way bypass and a water way bypass pipes; the air way bypass pipe is connected with the air outlet of the exhaust heater, and the water way bypass pipe is connected with a return water pipe; a sensor is mounted on the water outlet of the exhaust heater; a controller is connected with the sensor and the actuator via a wire; the forced radiator and the defroster are arranged in a compartment. The invention does not consume the fuel with high heat efficiency, and has no effect on the motor and can help the motor to cold starting.

Description

technical field [0001] The invention relates to an automobile heater, in particular to an intelligently controlled plumbing-type heater capable of utilizing engine coolant and exhaust waste heat at the same time. Background technique [0002] Traditional car heaters use the waste heat of the engine coolant for heating or use independent heat sources for heating, but the use of the waste heat of the engine coolant for heating is small enough to meet the heating requirements of large and medium-sized passenger cars in cold regions. Although heat source heating can meet the heating needs, it needs to consume fuel, and the heating cost is relatively high, and the exhaust gas discharged into the atmosphere will also cause environmental pollution. In recent years, there have also been heaters that utilize both coolant and exhaust waste heat for heating. However, there are disadvantages such as difficulty in cold engine start, slow heating of the cabin, and excessive cooling water ...

Problems solved by technology

[0002] Traditional car heaters use the waste heat of the engine coolant for heating or use independent heat sources for heating, but the use of the waste heat of the engine coolant for heating is small enough to meet the heating requirements of large and medium-sized passenger cars in cold regions. Although heat source heating can meet the heating needs, it needs to consume fuel, and the heating cost is high, and the exhaust gas of combustion will also cause environmental pollution when discharged into the atmosphere.

In recent years, there have also been heaters that use coolant and exhaust waste heat for heating at the same time, but there are disadvantages such as difficulty in starting the engine cold, slow temperature rise in the compartment, and excessive cooling water recoil after the water temperature is too high, which increases the load on the engine.
