Abstract
The heat radiator fan includes blades and motor driving the blades to rotate. The motor includes stator casing, front end cap, back end cap, commutator and front bearing, the stator casing is drawn together with the front end cap. Compared with available technology, the present invention has the advantages of good sealing performance, high reliability, less material consumption, low cost, small size and wide application range.
Description
Technical field
The present invention relates to a kind of fan, relate in particular to a kind of radiator fan that is used for vehicular engine and air-conditioning system.
Background technique
At present, the motor that radiator fan uses in automobile or the car is made the structure of elongated " straight cylinder type " or " tablet " usually, and its common characteristic is to connect forward and backward end cap integrally stretching, that be stamped to form of bearing support and the stator of motor is assembled by two.The mounting plate of motor generally all butt-joint be fixed on the motor stator external diameter.Along with constantly bringing forth new ideas of car technology, the arrangement thing in the car front-body case is more and more, and is more and more littler to the volume requirement of cooling fan.And the structure that present motor is adopted as shown in Figure 1; It is generally by forward and backward end cap, stator, and armature, brush spring, forward and backward bearings etc. are assembled.And said structure makes that radiator fan is difficult to do forr a short time again.
Summary of the invention
Technical problem to be solved by this invention provides a kind of radiator fan, and it adopts the motor of integrally stretching type, can dwindle the volume of existing motor greatly, thereby dwindles the volume of radiator fan greatly.
In order to solve the problems of the technologies described above, the invention provides a kind of radiator fan, it comprises fan blade and is used to drive the motor that fan blade rotates, described motor comprises stator cage, front cover, rear end cover, commutator, fore bearing, the casing of wherein said stator and front cover integrally stretching are integral, thereby form the integrally stretching casing.
The present invention compared with prior art has the following advantages:
1, good seal performance can improve reliability.
2, consumable material is few, can reduce cost.
3, volume is little, and using scope is big.
Description of drawings
Fig. 1 is the structural representation of existing radiator fan.
Fig. 2 is an embodiment's of a radiator fan of the present invention structural representation.
Fig. 3 is another embodiment's of a radiator fan of the present invention structural representation.
Embodiment
As shown in Figure 2: radiator fan of the present invention comprises fan blade 1 and is used to drive the motor 2 that fan blade rotates, described motor 2 comprises stator cage, front cover, the casing of described stator and front cover are integral by 1.5mm Plate Steel integrally stretching, thereby form integrally stretching casing 21, can reduce the infiltration slit like this, but also economical with materials.
Described motor 2 also comprises rear end cover 22, described rear end cover 22 and described integrally stretching casing 21 clampings, and be provided with an annular flange in the joint, and can be used for storing sealing silica gel 26, infiltrate motor to prevent rainwater.
Described motor 2 also comprises a commutator 23, and it is ladder-type structure, thereby can dwindle the radially installation dimension of motor.
Described motor 2 also comprises a fore bearing 24, and its top is provided with a baffle plate 25, but prevention of water flows to fore bearing along the motor external diameter.
Described fan blade 1 is provided with a water holding ring 11, can prevent that rainwater from infiltrating motor.
