Abstract
The utility model relates to an axial cooling system for a water-cooled motor, which comprises a frame outer wall, a cooling plate and a frame inner wall. The axial cooling system is characterized in that the cooling plate is cast from a plurality of bored lattens. The cooling system effectively reduces thermoresistance and improves heat transfer efficiency by changing the shape and structure of the cooling plate. Furthermore, the appearances of the surfaces of the frame walls are changed, thus improving the roughness of the surface of the tube wall to enable the eddy flow to bring the flow thereof into full play; therefore heat transfer efficiency is improved and radiating area is increased, which is good for heat exchange.
Description
Technical field
The utility model relates to the cooling heat radiation system of motor, relates in particular to the axial cooling system radiator structure of a kind of water-cooled machine.
Background technology
At present, general small-sized water-cooled machine is the internal water cooling structure, having in its end cap radially has radially between heat dissipation channel, support shell and the stator core or axial heat dissipation channel, forms the coolant circulation circuit by being tightly connected, when the fluid that flows into metered flow can cool off motor.In the axial heat dissipation channel structure of support, usually use the straight fin of rectangle to be arranged in heat-radiation loop, its axial section as shown in Figure 1, comprise support outer wall 1 ', fin 2 ', inboard wall of base 3 ', fin 2 ' is generally straight rectangle, arrange and form fluid heat-radiation loop 4 ', when fluid flows through the wall of band fin 2 ', carry out heat exchange with inboard wall of base 3 ' surface by fin 2 ' surface.
But, because traditional straight fin thermal transmission coefficient and flow resistance coefficient are all less, fin stretches in the middle of the fluid, there is thermal conduction resistance in fin inside, reduced the heat transfer efficiency of fin along the temperature gradient on the fin height, so the heat transfer efficiency of fin is lower than the heat transfer efficiency of machine wall surface.On the other hand, comparatively smooth through metalworking support wall surface, when fluid flow through the passage of straight fin row formation, the direction of fluid was constant and be parallel to the machine wall surface, and fluid causes heat transfer efficiency to descend at machine wall surface and fin surface do laminar motion thus.Therefore, the heat transfer efficiency of the straight fin of rectangle is not high.
Summary of the invention
In order to overcome the existing problem of above-mentioned general water-cooled machine cooling system, the utility model aims to provide the axial cooling system radiator structure of a kind of improved water-cooled machine, to improve radiation effect of motor.
The axial cooling system radiator structure of a kind of water-cooled machine described in the utility model comprises support outer wall, fin, inboard wall of base, it is characterized in that: described fin forms by dashing the foil casting that some holes are arranged.
In the axial cooling system structure of above-mentioned water-cooled machine, the aperture of described fin surface is distributed in the fin top.
In the axial cooling system structure of above-mentioned water-cooled machine, described support outer wall inner surface, inboard wall of base outer surface are radially processed several grooves that distribute respectively.
Owing to adopted above-mentioned technical solution, the present invention makes the thermal resistance boundary layer constantly break, form strong disturbance by the aperture that gathers on the fin, has reduced friction or local loss thereby improved heat transfer property and reduced flow resistance.In addition,, improved the roughness of support wall, made friction factor increase the turbulent motion that has fully developed fluid, improved heat transfer efficiency, increased area of dissipation simultaneously, helped exchange heat at support wall surface fluting.
Description of drawings
Fig. 1 is existing internal water cooling structure axial section;
Fig. 2 is the utility model internal water cooling structure axial section.
Embodiment
As shown in Figure 2, the utility model, that is: the axial cooling system radiator structure of a kind of water-cooled machine, comprise support outer wall 1, fin 2, inboard wall of base 3, wherein: fin 2 has the foil punching press or the rolling in some holes to form by dashing, and the aperture 4 on fin 2 surfaces is distributed in the top of fin 2.
Support outer wall 1 inner surface, inboard wall of base 3 outer surfaces are radially processed several grooves that distribute respectively.
In sum, the present invention promotes turbulence, separation and the destruction thermal resistance boundary layer of fluid by changing fin profile and structure, makes that fluid forms strong disturbance in passage, constantly break in the boundary layer and regenerates, thereby reduce thermal resistance effectively, improve heat transfer efficiency.In addition, by changing support wall surface profile, improve the tube wall surface roughness, fully developed flow body Turbulence Flow has improved heat transfer efficiency, has increased area of dissipation simultaneously, helps exchange heat.
Below embodiment has been described in detail the utility model in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details among the embodiment should not constitute qualification of the present utility model, and the scope that the utility model will define with appended claims is as protection range of the present utility model.
