Abstract
An engine prewarming device with a pump for an automobile cold-start uses ordinary home power and uses a built-in centrifugal pump and an electric heating element to heat up the engine winterization fluid. The device comprises a casing, a blade wheel, a motor and an electric heating element, wherein the casing is provided with a water inlet and a water outlet, the motor is wholly or partly arranged in the casing, the electric heating element is arranged between the casing and the motor and the blade wheel faces rightly the water inlet and integrates with the casing into a centrifugal pump structure. The motor is wholly or partly arranged in the casing, thereby the length in the direction of installing the motor shaft can be very small, the installation space can shrink much and the engine prewarming device can be conveniently arranged in the automobile.
Description
The utility model relates to a kind of motor car engine preheater.
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.
The purpose of this utility model provides a kind of engine preheater with pump.The existing same device of its volume ratio is much smaller, can be installed on the Motor Vehicle more easily.
The purpose of this utility model is achieved like this: preheater comprises heating chamber shell, impeller, axle, rotor, rotor shell, stator, electric heating element etc.Wherein, the heating chamber shell communicates with engine coolant by water intake on the heating chamber shell and water outlet with the seal casinghousing that rotor shell constitutes.Electric heating element, rotor are arranged, axle and impeller in the heating chamber.Motor stator is outside heating chamber.Impeller is contained on the axle, and impeller forms a centrifugal pump structure over against water intake and with the part inwall of housing.Rotor is in rotor housing.Axle is contained on rotor shell and the pedestal.
Because adopt such scheme, motor is all or part of in housing, 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.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the engine preheating system structural representation of band pump.
Fig. 2 is the engine preheating system embodiment's of band pump a structural representation.
Among the figure, 1, water intake 2, impeller 3, housing 4, water outlet 5, electric heating element 6, motor 7, terminal box 8, motor stator 9, rotor 10, motor shaft 11, insulating bush
In the engine preheating system embodiment of band pump shown in Figure 2, input voltage AC220V, electric heating element (5) is an electric heating tube, power 1200W, the rated power 20W of motor, motor stator (8) are sealed in the plastic insulation covering (11) fully, and plastic insulation covering (11) is fixed on the housing (3), and forming an airtight cavity with housing, rotor (9) is a permanent-magnet material.Impeller (2) is contained on the motor shaft (10).Impeller (2) forms a centrifugal pump structure over against water intake (1) and with the part inwall of housing (3), when rotor (9) impeller (2) is rotated, engine fluid is by in water intake (1) inspiration housing (3), after the heating of the electric heating element (5) in the housing (3), flow back to motor by water outlet (4).What present embodiment adopted is the waterproof magneto that can be immersed in the antifreeze liquid, also can go up at motor shaft (10) in other embodiments mechanical seal is installed.The water outlet of present embodiment (4) is on the sidewall of housing (3), and in other embodiments, water outlet (4) also can be in other place of housing (3), and its Way out is unrestricted.
Claims (2)
1. be with the engine preheating system of pump, this device comprises housing, impeller, motor, electric heating element, water intake and water outlet are arranged on housing, it is characterized in that: motor is all or part of in housing, electric heating element is contained in the space between housing and the motor, impeller is contained on the motor shaft, and impeller forms a centrifugal pump structure over against water intake and with inner walls in housing.
2. the engine preheating system of band pump according to claim 1 is characterized in that: housing is the cavity of a sealing, and the inner chamber of housing communicates with engine fluid by water intake and water outlet.
