Abstract
The utility model relates to an engine preheater with a built-in pump, which is used for the cold starting of a mobile vehicle. The utility model using the ordinary civilian power supply utilizes a built-in centrifugal pump and an electrothermal element to heat the antifreeze of an engine. The utility model includes a shell, a vane wheel, an electric motor and the electrothermal element, a water inlet and a water outlet are arranged on the shell, the vane wheel faces the water inlet, and the vane wheel and the shell form a centrifugal pump structure. Because the whole or the part of the electric motor is positioned in the shell, the length of the preheater in the axial direction of the electric motor can be produced short, the volume of the preheater can also be greatly reduced, and therefore the preheater can be conveniently mounted on the mobile vehicle. A rotor made of permanent magnetic materials operates in the antifreeze.
Description
The utility model relates to a kind of motor car engine Preheating unit.
The common engine preheater that has recycle pump is made up of three relatively independent parts: heating chamber, pump and motor.This three part generally is to arrange along the direction of motor shaft, as ZL99223027.6, ZL98240295.3.The shortcoming of this type of device is that the axial length of motor is long, and the volume ratio of device is bigger, and relatively difficulty is installed on Motor Vehicle.When adopting mechanical seal that motor shaft is sealed, the problem that cooling liquid is leaked also can appear.
The purpose of this utility model provides a kind of engine preheating system with internal pump.The existing same device of its volume ratio is much smaller, can be installed in more easily on the Motor Vehicle, also will solve the cooling liquid leakage problem simultaneously.
The purpose of this utility model is achieved like this: device comprises heating chamber, impeller, stator, stator coil, rotor, rotor shell, electric heating element, motor shaft etc.Wherein, heating chamber is the chamber of a sealing, and heating chamber has water intake and water outlet, heating chamber communicates with engine coolant by water intake and water outlet, and rotor is a permanent-magnet material, and rotor is in rotor shell, rotor is contained on the motor shaft, and motor shaft is contained on rotor shell and the pedestal.The rotor shell inner chamber communicates with heating chamber, and the cooling liquid in the heating chamber can flow in the rotor shell inner chamber.Electric heating element is in heating chamber, and impeller is contained on the motor shaft, and impeller forms a centrifugal pump structure over against water intake and with the heating chamber inwall in heating chamber.When rotor rotates under the driving of stator and stator coil, rotor rotates together by the motor shaft impeller, engine coolant is drawn into heating chamber by water intake, engine coolant is after the electric heating element heating, discharge heating chamber by water outlet, flow back to motor, this be one with the hydronic process of engine coolant.。
Owing to adopt such scheme, the axial length of device motor can be done very shortly, and the volume of device also can dwindle many, can be installed on the Motor Vehicle easily.Because rotor adopts permanent-magnet material, rotor and motor shaft are sealed in rotor shell and the heating chamber, and rotor can rotate in cooling liquid, and during this device busy, cooling liquid can not leak into the outside of device.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the engine preheating system of band internal pump and an one embodiment's structural representation.
Fig. 2 is the left view of the motor part of embodiment among Fig. 1.
Among the figure, 1, impeller 2, motor shaft 3, pedestal 4, rotor 5, stator
6, rotor shell 7, stator coil 8, water outlet 9, electric heating element
10, heating chamber 11, heating chamber housing 12, water intake
In the engine preheating system embodiment of band internal pump shown in the drawings, input voltage AC220V, electric heating element (9) is an electric heating tube, power 1200W, the rated power 15W of motor, rotor (4) is a permanent-magnet material.Impeller (1) is contained on the motor shaft (2).Impeller (1) forms a centrifugal pump structure over against water intake (12) and with the part inwall of heating chamber (10).When rotor (4) rotated by motor shaft (2) impeller (1), engine coolant after electric heating element (9) heating in being heated chamber (10), was flowed back to motor by water outlet (8) by in water intake (12) inspiration heating chamber (10).The water outlet of present embodiment (8) is on the upper side wall of heating chamber housing (11), and in other embodiments, water outlet (8) also can be in other place of heating chamber housing (11), and its Way out is unrestricted.
Claims (4)
1. be with the engine preheating system of internal pump, this device comprises heating chamber, impeller, stator, stator coil, rotor, rotor shell, electric heating element, motor shaft, heating chamber has water intake and water outlet, rotor is contained on the motor shaft, and electric heating element is in heating chamber, and impeller is contained on the motor shaft, it is characterized in that: rotor is a permanent-magnet material, rotor is in rotor shell, and the inner chamber of rotor shell communicates with heating chamber, and impeller forms a centrifugal pump structure over against water intake and with the heating chamber inwall in heating chamber.
2. the engine preheating system of band internal pump according to claim 1 is characterized in that: heating chamber is the chamber of a sealing that communicates with the rotor shell inner chamber and communicate with engine coolant by water intake and water outlet.
3. the engine preheating system of band internal pump according to claim 1 is characterized in that: rotor shell is the housing that its inner chamber only communicates with heating chamber.
4. the engine preheating system of band internal pump according to claim 1 is characterized in that: the cooling liquid in the heating chamber can flow in the rotor shell inner chamber.
