Description

Cooling device with additional spoiler, motor and manufacturing method thereof, and cooling device modification method

The present invention relates to a cooling device, especially a cooling device with a spoiler, a motor and a manufacturing method thereof, and a method for installing the spoiler.

The motor can use the input power to convert into kinetic energy output, but the conversion process will produce energy loss (such as hysteresis loss, rotation loss, stray loss), part of these energy loss will be converted into heat, which will cause the motor temperature to rise, too high In addition to lowering the working efficiency of the motor and shortening the service life, the temperature of this will also limit the maximum power of the motor.

Therefore, the motor is usually combined with a heat dissipation structure, for example, the motor housing uses a heat-conducting material, a water-cooling kit, and so on. Regarding the previous cases of water-cooling kits, for example, there is the "Water-cooling structure of electric motor" in the Republic of China Invention Patent Publication No. I413349, which includes a motor body, a heat dissipation base and a spoiler. The aforementioned motor system is sheathed outside the heat dissipation base. The aforementioned heat dissipation base has at least one main flow channel provided on the outer peripheral side thereof. The aforementioned turbulence portion is arranged in the main flow channel to generate a flow turbulence effect on the fluid in the main flow channel, thereby increasing the heat transfer efficiency.

However, the above-mentioned spoiler is a main channel integrally connected to the heat dissipation base, and usually requires mold molding in manufacturing, which requires expensive mold opening costs, which is not conducive to reducing manufacturing costs. In addition, this method is not suitable for improving existing cooling devices.

In view of this, the inventor of the present invention proposes a cooling device with an additional spoiler in order to easily shape the spoiler, which includes: a cooling component and a spoiler. The cooling assembly includes a sleeve and an inner liner. The sleeve or/and the inner liner have a spiral groove to define a spiral channel between the sleeve and the inner liner for a cooling flow to pass through. The spoiler has flexibility so as to be wound around the spiral groove, and a spoiler portion extending along the spiral channel is formed in the cooling assembly to generate a spoiler effect on the cooling flow.

Further, the spoiler is an elastic coil or a flexible wire.

Further, the spoiler is provided with a plurality of spoiler features at intervals.

Further, the spoiler is a flexible plate body, the spoiler includes a first plate surface and a second plate surface, the first plate surface and the second plate surface are both provided with a plurality of fins at intervals, the first Each of the aforementioned fins of a plate surface and each of the aforementioned fins of the second plate surface are inclined and opposite to each other to form a plurality of fin groups, and the spoiler has a through the first plate surface And the plurality of circulation holes on the second plate surface, each of the circulation holes is adjacent to the fin group.

Further, the spoiler is a spiral-shaped flexible plate body, and the spoiler is provided with a plurality of spoiler features at intervals. The aforementioned spoiler features are oblique convex ribs, oblique grooves, V-shaped convex ribs, and V-shaped concave Any one or combination of grooves, W-shaped ribs, and W-shaped grooves.

Furthermore, the cross-sectional shape of the spiral channel is round, square, diamond or trapezoid.

The present invention is also a motor that includes the cooling device with the additional spoiler as described above. The motor further includes a stator and a rotor. The stator is installed in the cooling device, and the rotor is rotatably located in the stator.

The present invention is also a method for manufacturing a cooling device, which includes forming a sleeve or/and an inner liner into a spiral groove to define a spiral channel between the sleeve and the inner liner; and arranging a spoiler around The spiral groove forms a spoiler extending along the spiral channel in the cooling assembly.

The present invention is also a motor manufacturing method, including forming a sleeve or/and an inner liner into a spiral groove to define a spiral channel between the sleeve and the inner liner; and arranging a spoiler around the Spiral grooves to form a spoiler extending along the spiral channel; a stator is installed in the inner liner, and the rotor is rotatably located in the stator.

The present invention is also a method for refitting a cooling device. A sleeve and an inner lining of an existing cooling device are disassembled from each other; a spoiler is arranged around the sleeve or/and a spiral groove of the inner lining; The sleeve and the lining are reassembled so that a spiral channel is defined between the sleeve and the lining to form a spoiler extending along the spiral channel.

According to the above technical features, the following effects can be achieved:

1. The spoiler is an additional type, which can be wound around the spiral channel with flexibility, that is, a spoiler extending along the spiral channel can be formed in the cooling assembly to achieve the purpose of turbulence for the cooling flow. There is no need to redesign new molds in manufacturing, which can reduce the cost of development. On the other hand, it is also suitable for improving the cooling performance of used aging motors and generators, which can reduce the cost of equipment replacement.

2. Since the spoiler is an additional type, it is convenient to separately process various spoiler features (such as grooves, fins, flow holes, column fins, dimples, etc.), which helps to generate a more complex vortex field for the cooling flow. To further enhance the heat exchange effect of the cooling flow.
