Abstract
An engine preheater automatically provided with a pump belongs to the engine electric heater field. The purpose of the utility model is to solve the defects of the current similar designs of complex sealing structure, poor reliability, as well as large size and water resistance. The utility model is technically characterized in that an electric heater element is outside a heating cavity and is heated through the heating cavity wall; an impeller in the heating cavity faces a water inlet and forms a centrifugal pump with the heating cavity; a motor rotor is connected with the impeller in parallel and is arranged in the heating cavity. The utility model can be used for engine preheating for the cold start-up of various motor vehicles in winter.
Description
Technical field
The utility model is about a kind of automatic band pump engine preheater, belongs to motor car engine electric heater field, also can be applied to others.
Background technique
This type of engine preheater is made of heating chamber and water intake thereof and water outlet, electric heating element, impeller and motor etc., it typically is single cavity configuration, and promptly electric heating element and impeller all are arranged in the same heating chamber; Double cavity structure is also arranged, and promptly electric heating element is arranged in the independent heating chamber, and in another one and chamber that heating chamber communicates impeller is set, and in fact double cavity structure is exactly heating chamber and series connection of pumps.Single cavity configuration is simple relatively, water resistance is little, is present developing direction, but still has some defectives, and mainly be, electric heating element is arranged in the heating chamber, sealing difficulty during extraction electrode; Impeller in heating chamber and motor (rotor) in heating chamber outer driving shaft seal complex, this two aspect causes whole preheater reliability or poor stability, volume is big, water resistance is still big.
Summary of the invention
The purpose of this utility model is to propose band pump engine preheater automatically, its simple in structure, easy manufacturing, reliability height, and volume is little simultaneously, and water resistance is also little.
The purpose of this utility model is to realize by such technological scheme: a heating chamber that is surrounded by heating chamber wall and water intake and water outlet, electric heating element is outside heating chamber and by the heating of heating chamber wall, impeller is in heating chamber and face water intake and heating chamber and form centrifugal pump, and rotor and impeller link and in heating chamber.
The producible beneficial effect of the utility model is, compare with existing single cavity configuration preheater since rotor in heating chamber and electric heating element outside heating chamber, greatly simplified sealing configuration, reduced manufacture difficulty, improved sealing reliability; The big good effect of heat exchange of heating chamber internal surface area relatively just can reduce the volume of heating chamber and whole preheater; The reducing of heating chamber also reduced the sectional area sudden change, further reduced water resistance; Be equivalent to improve the quality and the thermal inertia thereof of electric heating element in addition by heating chamber wall heating, also just improved the reliability of the temperature automatically controlled and overheat protective function of preheater.
Description of drawings
Fig. 1 is a vertical section structure schematic diagram of the present utility model.
Fig. 2 is an embodiment's of the present utility model vertical section structure figure.
According to Fig. 1, the utility model mainly comprises heating chamber wall 1 and water intake 2 and water outlet 3, heating chamber 4, impeller 5, rotor 6 and electric heating element 7 etc.
Embodiment
This embodiment that Fig. 2 describes has summarized and has realized best way of the present utility model, and it mainly comprises parts such as heating chamber wall 1 and water intake 2 and water outlet 3, heating chamber 4, impeller 5, rotor 6, electric heating element 7, motor stator 8.Wherein heating chamber wall 1 is made of A, B, C three parts, connects with form of flanges with rubber seal therebetween, and its sectional shape all adopts circle to be convenient to make.The A part is made with the steel plate drawing and forming, and water outlet is arranged on top so that get rid of the gas in the heating chamber and give full play to pumping function; The B part casts from wherein with the aluminium alloy compression casting manufacturing and with the copper electric heating tube of electric heating element, conducts heat; C partly adopts the aluminum alloy manufacturing, the inboard dress of C part heating chamber permanent magnet machine rotor, and its outside dress motor stator, motor stator is by C part drive motor rotor; Rotor connects with impeller by an axle D, also clutch is housed so that electric motor starting between impeller and the axle, and the O type circle E that adorns axle on plays impurity in the isolation non freezing solution, influences motor between partly and moves to avoid impurity to enter rotor and C.Electrothermal tube power AC220V1100W, motor power AC220V40W.
According to Fig. 2, structure of the present utility model and working principle are such, heating chamber wall 1 surrounds heating chamber 4 with water intake 2 and water outlet 3, except that being complete airtight chambeies by heating chamber 4 water intake 2 and water outlet 3 and the exterior, electric heating element 7 is contained in outside the heating chamber, be electric heating element or be arranged in the heating chamber wall 1 or be affixed on its outside and heat the heating chamber wall that impeller 5 links with rotor 6 and together is contained in the heating chamber 4, impeller 5 faces water intake 2 and is provided with.During work, rotor 6 is the impeller rotation under the driving of stator, the impeller 5 of rotation forms centrifugal pump with heating chamber 4, centrifugal pump sucks the motor non freezing solution of outside from water outlet 3 discharge formation circulations from water intake 2, and the circuit non freezing solution is heated chamber wall heating and brings motor with heat and realizes engine warming up.
