Description
Technical field
The utility model relates to a kind of motor cooling device, particularly a kind of motor cooling device that uses heat pipe heat radiation.
Background technology
Motor mainly contains three kinds of types of cooling on the market at present, and natural cooling is air-cooled, the shell water-cooled.
The machine with natural cooling that relies on the radiating ribs heat radiation manufactures the simplest, but the cooling effect of this motor is very undesirable, usually overheatedly causes motor to burn out.
Current modal on the market motor is to adopt air-cooled form.It is at the electric machine main shaft tail end fan to be installed, and fan is along with electric machine main shaft rotates together.The structure of this motor is no doubt also simple, but fan has increased the overall dimension of motor, and the rotation of fan brought noise and increased the power consumption of motor itself, has promptly reduced the rated power of motor.In addition, if the time of using has been grown, perhaps run into the area of many dusts, untight fan sticks dust especially easily, has so both increased the burden of motor, has reduced cooling effect again.
The good cooling results of shell water-cooled machine, but but because on motor housing, added cyclic water jacket, make the manufacturing of motor housing become complicated more difficult.In addition, compare with air-cooled and machine with natural cooling, the shell water-cooled machine also need increase by a cover water-cooling apparatus, makes cost higher.
The utility model content
The purpose of this utility model is to overcome aforesaid drawbacks of the prior art, and a kind of good cooling results is provided, the efficient height, and noise is low, and is reliable, and wiring is easy to the motor cooling device.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of motor cooling device that uses heat pipe heat radiation is provided, it is characterized in that: it comprises motor housing (1), preceding heat pipe sheath (2), front end housing (3), heat pipe (4), heat pipe sheath trip bolt (5), heat pipe inlet slot (6), rotor main shaft (7), bearing (8), rotor (9), stator winding (10), motor power-supply wire (11), heat pipe outlet slot (12), cover (13) and rear end cap (14) are managed and protected in after heat, heat pipe sheath (2) is arranged on the front end of described motor housing (1) before described, the rear end that is set on this motor housing (1) is managed and protected in described after heat, described after heat is managed and protected and has been put several heat pipe mounting grooves, and preceding heat pipe sheath is provided with a heat pipe inlet slot, after heat is managed and protected and is put a bigger heat pipe outlet slot, manage and protect the heat pipe mounting groove that puts is attached to the evaporation ends chucking of heat pipe on the motor housing by preceding heat pipe sheath and after heat, the heat pipe porch of heat pipe sheath in the past enters in the preceding heat pipe sheath lumen, heat pipe after bending again respectively in the past each heat pipe mounting groove of heat pipe sheath come out to extend the heat pipe mounting groove that cover is managed and protected in corresponding after heat, enter into after heat manage and protect the cover inner chamber, after the bending all heat pipes again all from after heat manage and protect the cover exit come out to the condensation end of heat pipe.
The heat transferred of distributing during motor rotation is behind motor housing, and the heat pipe evaporation ends that is close on the motor housing is heated, and the liquid in the capillary evaporates rapidly, and steam is at the dirty condensation end to heat pipe of small pressure differential.Steam is emitted heat at condensation end, and regelation afterwards becomes liquid, and liquid flows back to evaporation ends along porous material by the effect of capillary force again, and so circulation is more than.
Manage and protect the fastening screw of cover (5) preceding heat pipe sheath (2) and after heat are managed and protected the rear and front end that cover (13) is separately fixed at motor housing (1).
The rear and front end of rotor main shaft (7) is equipped with a bearing (8) respectively.
The utility model has the advantages that: because heat pipe is equipped with in the motor outside, the liquid in the heat pipe is heated at evaporation ends, and the back is rapid evaporates, and steam is at the dirty condensation end to heat pipe of small pressure differential.Steam is emitted heat at condensation end, and regelation afterwards becomes liquid, and liquid flows back to evaporation ends along porous material by the effect of capillary force again, and so circulation is more than.This motor cooling device with heat pipe heat radiation just adds forward and backward heat pipe sheath and several heat pipe on motor housing, original relatively machine with natural cooling or ventilated machine need not to do much changes.In addition, need not as the shell water-cooled machine, also will add a cover cooling recirculation system with the motor of heat pipe heat radiation, as water pump, storage tank, auxiliary equipments such as radiator.Adopt the motor of the utility model motor cooling device to have better heat radiating effect, make simple, easy to assembly.

Embodiment
Following content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
To shown in Figure 5, the utility model comprises motor housing 1, preceding heat pipe sheath 2, front end housing 3, heat pipe 4 as Fig. 1, heat pipe sheath trip bolt 5, heat pipe inlet slot 6, electric machine main shaft 7, bearing 8, rotor 9, stator winding 10, motor power-supply wire 11, heat pipe outlet slot 12, cover 13, rear end cap 14 are managed and protected in after heat.Heat pipe sheath 2 is arranged on the front end of described motor housing 1 before described, the rear end that is set on this motor housing 1 is managed and protected in described after heat, described after heat is managed and protected on the cover 13 several heat pipe mounting grooves, and preceding heat pipe sheath is provided with a heat pipe inlet slot, the heat pipe outlet slot that puts is managed and protected in after heat, manages and protects the heat pipe mounting groove that puts by preceding heat pipe sheath and after heat the evaporation ends chucking of heat pipe is attached on the motor housing.
