Description

Technical Field

[0001] This utility model relates to the technical field of heating devices for new energy vehicles, specifically a water heater for preheating the engine of a new energy vehicle. Background Technology

[0002] In many parts of northern my country, cold-starting car engines is a common problem during winter. When the ambient temperature is extremely low, the engine block temperature and engine oil temperature also drop significantly, especially as the oil viscosity increases due to the low temperature. In such conditions, forcing a cold start will increase wear on the moving parts of the engine due to the reduced lubrication capacity of the engine oil. Furthermore, the low engine block temperature can lead to incomplete combustion of gases in the cylinders during a cold start, resulting in increased fuel consumption, more exhaust gases, and higher levels of harmful substances. Therefore, a water heater is needed to preheat the engine.

[0003] For example, Chinese patent CN111997809A discloses a water-heated engine warm-up device for cold starting of automobile engines. However, existing water heaters are only suitable for preheating automobile engines and are not suitable for the long-term operating conditions of new energy vehicles. Therefore, this utility model proposes a water heater for preheating new energy vehicle engines to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a water heater for preheating new energy vehicle engines, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water heater for preheating a new energy vehicle engine, comprising: a water tank, a combustion-supporting impeller, and a motor fixed inside a housing; a water jacket is fixedly installed at the outer end of the water tank; a housing temperature sensor and a water temperature sensor are respectively installed at the upper end of the water jacket; an outlet pipe and an inlet pipe are respectively fixedly installed at the upper end of the water tank; and a combustion chamber is fixedly installed at one end of the water tank by bolts.

[0006] The combustion-supporting wind turbine and the motor are fixedly connected by a motor bracket and a water tank. A controller is fixedly installed at one end of the motor bracket by bolts.

[0007] The lower end of the combustion chamber is fixedly equipped with an exhaust port, an air intake port, and an oil inlet port.

[0008] Preferably, an inspection cover is provided on one side of the upper end of the housing.

[0009] Preferably, the water tank and the water jacket are connected by three fixing bolts, and an O-ring is fixedly installed at the connection between the water tank and the water jacket.

[0010] Preferably, the inner ends of the water outlet pipe and the water inlet pipe are connected to the interlayer between the water tank and the water jacket, and the outer ends of the water outlet pipe and the water inlet pipe extend out of the shell.

[0011] Preferably, the controller includes a controller motherboard housing fixed to the outer end of the motor bracket, and the controller motherboard is fixedly installed inside the controller motherboard housing and sealed by the controller motherboard housing sealing gasket.

[0012] Preferably, the water temperature sensor and the housing temperature sensor are fixed to the water jacket by a sensor clamping plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention uses a controller to control a motor that drives a combustion air impeller to rotate. Combustion air enters the combustion chamber through the air inlet under the action of the combustion air impeller. When the oil pump receives the oil pumping signal from the main board controller, it delivers fuel through the oil inlet to the combustion chamber to mix with the combustion air. The mixture of fuel and combustion air is ignited under the high temperature of the ignition plug and burns in the combustion chamber, transferring the heat generated by combustion to the water tank. The exhaust gas generated by combustion is discharged into the atmosphere through the exhaust port. The antifreeze that needs to be heated is delivered to the cavity formed by the water tank and water jacket through the water inlet pipe by the electric water pump, and after taking away the heat of the water tank, it enters the antifreeze pipeline system that needs to be heated in the car through the water outlet pipe. It is suitable for both preheating of car engines and for the working conditions of heating during long-term operation of new energy vehicles. Attached Figure Description
