Abstract
The utility model provides a heat exchanger, which is characterized by comprising a cooling pipe and an air outlet connected with the cooling pipe. The air outlet is provided with a blower fan, and the blower fan directly absorbs air from the exterior of the heat exchanger and blows along a preset direction. The utility model also provides a generator or motor with the heat exchanger. The generator or motor comprises a generator or motor body and a slip ring connected with the generator or motor body, and the heat exchanger is used for cooling the generator or motor body and the slip ring.
Description
Technical field
The utility model relates to a kind of heat exchanger and the motor that comprises it or generator.
Background technology
Motor or generator because internal loss produces heat, therefore need coolant to carry out its winding and iron core cooling in when work, with the temperature that maintains each several part in the limit allowing.Meanwhile, also need to carry out cooling to being positioned at the slip ring at motor or place, generator end.
Traditional air to air heat exchanger is current more conventional heat exchanger, wherein can be from the middle part of motor to blowing up for winding and iron core being carried out to the air of a cooling wind path, then from the front end of cooling water pipe or rear end to blowing down.Secondary wind path is blown into outside cold air in cooling water pipe, for the air of a cooling wind path.Air outlet is often arranged on the end of secondary wind path for guiding air-flow, so that air-flow is more smoothly derived, reduces the impact of outside disorderly air-flow simultaneously.
In order to carry out cooling to the slip ring at motor or place, generator end, current a kind of scheme is to be parallel to secondary wind path an independent air channel to be set and guided plate (as shown in the dotted line in Fig. 1) to be set on air outlet to guide the wind in this air channel into slip ring, as shown in the wind path in Fig. 1.But, can larger air quantity and the blast of loss by this cooling means, and the temperature of cooling-air did not cause unnecessary rising with regard to the cooling water pipe because of by intersecting with wind path before entering slip ring unit.Current another kind of scheme is that independent cooling fan is installed on slip ring box.But this cooling mounting means will increase vibration risk and noise risk, also can take more space.
Utility model content
Execution mode of the present utility model provides a kind of heat exchanger, it is characterized in that, comprises cooling water pipe and the air outlet being connected with described cooling water pipe, on described air outlet, is provided with blower fan, and described blower fan is directly from the outside air amount of heat exchanger and blow to the direction of setting.
In one embodiment, described heat exchanger comprises two blower fans, and described two blower fans are separately positioned on two sidewalls of described air outlet.
In one embodiment, on the air inlet of described blower fan, be also provided with air-ducting ring.
In one embodiment, in the outlet of described blower fan, be also provided with protective cover and/or protection network.
The utility model also provides a kind of generator, it is characterized in that, comprise generator body, the slip ring being connected with generator body and for described generator body and slip ring are carried out to cooling heat exchanger, wherein said heat exchanger is as front heat exchanger as described in arbitrary.
The utility model also provides a kind of motor, it is characterized in that, comprises motor body, the slip ring being connected with motor body and for described motor body and slip ring are carried out to cooling heat exchanger, and wherein said heat exchanger is as front heat exchanger as described in arbitrary.
In one embodiment, the direction of described setting is to point to the direction of described slip ring.

Embodiment
Below with reference to accompanying drawing, the specific descriptions of optional execution mode of the present utility model have been provided.The generator of below take is described as example, but structure of the present utility model also can be applied to motor completely.For simplified characterization, below no longer repeat.
As shown in Figure 1, whole generator comprises generator body 10, the slip ring 30 and the heat exchanger that are connected with generator body 10, and wherein said heat exchanger comprises cooling water pipe 20 and the air outlet 40 being connected with cooling water pipe 20.In order to improve cooling to slip ring 30, the utility model proposes a kind of air outlet structure as shown in Figure 2.
As shown in Figures 2 to 4, on air outlet 40, be provided with two centrifugal blowers 50 and 60.Centrifugal blower 50 and 60 for example can be arranged on two sidewalls of air outlet 40, can suck from the outside of air outlet 40 outside air like this, then be blown into the cooling slip ring of slip ring box (SRU) 30, and without turning back very large angle or by very long path.By this structure, saved the independent air channel that is arranged in secondary wind path below and the guided plate that is arranged at air outlet shown in Fig. 1, reduced air quantity and air loss, and the air sucking can not heated by a wind path.In addition, because centrifugal blower is located substantially on air outlet inner side, thereby avoided taking additional space.By the structure of reasonably optimizing, Novel air outlet and traditional air outlet after improving are not almost changed in overall dimension.Like this, can more effectively make cooling blast enter slip ring box, improve the air-flow efficiency cooling to slip ring.In addition, can increase embedded blower fan having under the prerequisite of same-interface size with traditional air outlet, thereby directly replace traditional air outlet of the generator of waiting to be delivered for use or moving.Under different applied environments, if need to the cooling effect of slip ring be adjusted, can in the situation that keeping identical installation dimension, select the blower fan of different capacity, thereby more easily change or lifting slip ring cooling effectiveness.This design can meet client's requirement to a great extent.
The position, the direction of blower fan air-out and the type of blower fan that should be appreciated that blower fan are not limited to above-mentioned execution mode, but can adjust according to the needs of cooling power.
In order to reduce air quantity and air loss in the center that makes the airflow direction of air outlet point to slip ring simultaneously, the outlet that centrifugal blower 50 and 60 can be arranged to blower fan directly towards slip ring box, for example, can arrange the support that centrifugal blower 50 and 60 are installed in air outlet.
In addition,, in order to reduce air intake air loss, can air-ducting ring 61 be set at the air inlet place of centrifugal blower 50 and 60.In order to meet the demand of degree of protection, can also on centrifugal blower 50 and 60, protective device be set.For example as shown in Figure 2, can be on the air inlet of centrifugal blower 60 protection network 62, to prevent that external object from entering centrifugal blower, and can be at the arranged outside protective cover 63 of air inlet, to prevent that for example water is splashed into centrifugal blower.
Although illustrate and described the utility model with reference to some preferred embodiment of the present utility model, but it will be appreciated by those skilled in the art that, in the situation that not deviating from spirit and scope of the present utility model as defined in appended claims, can to it, make a variety of changes in the form and details.
