Abstract

The utility model relates to a kind of strengthening heat convection device of liquid-cooled controller, belongs to the cooling system technical field of electric machine controller.Comprise cooling jacket, described cooling jacket is made up of some pipelines that be parallel to each other and that be communicated with, is provided with flow-disturbing annex in described pipeline, and described flow-disturbing annex is helicoidal structure.In the utility model, flow-disturbing annex has changed the turbulence characteristic of cooling fluid, reduce eddy region in water route, strengthen the turbulence intensity of cooling fluid, not only can make the flow velocity of cooling fluid in cooling jacket more even, and the heat that can make the self-heat power liquid that is cooled absorbs efficiently, improve the heat convection efficiency between cooling fluid and thermal conductive surface.

Description

The strengthening heat convection device of liquid-cooled controller
Technical field
The utility model relates to the cooling system of electric machine controller, is specifically related to a kind of strengthening heat convection device of liquid-cooled controller.
Background technology
Although the cooling system of existing motor controller can play cooling to motor controller system, but exist at water turn in the road, turbulent region diminishes, turbulence intensity step-down, water route is flowed inhomogeneous, has reduced the cooling effect between cooling night and conducting-heat elements.
Utility model content
The purpose of this utility model is exactly the defect for prior art, and a kind of strengthening heat convection device of liquid-cooled controller is provided.
The technical solution adopted in the utility model is: comprise cooling jacket, described cooling jacket is made up of some pipelines that be parallel to each other and that be communicated with, is provided with flow-disturbing annex in described pipeline, and described flow-disturbing annex is helicoidal structure.
Further, described some pipelines that be parallel to each other and that be communicated with are divided into first group and second group, one end of described first group and second group is communicated with respectively and meets at the first transverse tube place and the second transverse tube place, described the first transverse tube place is provided with cooling liquid inlet, described the second transverse tube place is provided with cooling liquid outlet, and common connection of the other end of described first group and second group meets at the 3rd transverse tube place.
In the utility model, flow-disturbing annex has changed the turbulence characteristic of cooling fluid, increase eddy region in water route, strengthen the turbulence intensity of cooling fluid, not only can make the flow velocity of cooling fluid in cooling jacket more even, and the heat that can make the self-heat power liquid that is cooled absorbs efficiently, improve the heat convection efficiency between cooling fluid and thermal conductive surface.
Brief description of the drawings
Fig. 1 is existing structure schematic diagram
Fig. 2 is the utility model structural representation.
1-cooling jacket, 2-cooling liquid inlet, 3-cooling liquid outlet, 4-the first transverse tube, 5-the second transverse tube, 6-the 3rd transverse tube, 7-flow-disturbing annex.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, is convenient to be well understood to the utility model, but they do not form and limit the utility model.
As shown in Figure 1, in existing cooling jacket 1 pipeline, cooling fluid, flows out from cooling liquid outlet 3 from cooling liquid inlet 2 after shunting.Between cooling fluid and cooling jacket 1 thermal conductive surface, there is heat convection.
As shown in Figure 2, the utility model comprises cooling jacket 1, described cooling jacket 1 is made up of some pipelines that be parallel to each other and that be communicated with, described some pipelines that be parallel to each other and that be communicated with are divided into first group and second group, one end of described first group and second group is communicated with respectively and meets at the first transverse tube 4 places and the second transverse tube 5 places, described the first transverse tube 4 places are provided with cooling liquid inlet 2, described the second transverse tube 5 places are provided with cooling liquid outlet 3, the common connection of the other end of described first group and second group meets at the 3rd transverse tube 6 places, in described pipeline, be provided with flow-disturbing annex 7, described flow-disturbing annex 7 is helicoidal structure.In cooling water channel of the present utility model, cooling fluid from cooling liquid inlet 2 through shunting after, converge at the 3rd transverse tube 6 places, then continue shunting, and flow out from cooling liquid outlet 3, in figure, the direction of arrow is coolant flow direction, spiral flow-disturbing annex 7 has increased the turbulence intensity of the cold ature of coal in main flow region, thereby the heat exchange between the cooling fluid of making and cooling jacket 1 thermal conductive surface 1.1 is more abundant, has improved heat exchange efficiency.
The content that this specification is not described in detail belongs to the known prior art of professional and technical personnel in the field.
