Abstract
The utility model discloses a water-cooled motor housing used for enhancing cooling effects. The water-cooled motor housing comprises a motor housing body. A spiral water channel is disposed on the wall of the motor housing body along the circumferential direction. The starting point of the spiral water channel is a water inlet while the terminal point of the spiral water channel is a water outlet. The two opposite sides of the cross section of the spiral water channel are in waved shapes. Overcoming defects of the cooling mode of a conventional water-cooled motor, the housing further increases the cooling effects of the water-cooled motor and effectively increases the power and the torque of the water-cooled motor under an equal size and weight condition.
Description
Technical field
The utility model relates to a kind of housing that is used to improve the water-cooled machine of cooling effect.
Background technology
For water-cooled machine, especially automobile-used water-cooled machine, its power and torque and cooling effect have confidential relation, cooling effect has restricted power and torque that motor can provide, increase the volume and weight that power of motor or torque often need to increase motor, yet because the vehicle arrangement space is limited, the motor volume increase is limited by vehicle space, the increase of motor weight also can increase the load of vehicle, and motor volume or weight increase mean that cost increases.As depicted in figs. 1 and 2, usually in the housing of water-cooled machine spirality channel 1 is set, the cross section of this spirality channel 1 is a rectangle 4, and this spirality channel 1 starting point is that water inlet 2, terminal point are delivery port 3, cooling water to delivery port 3 outputs, is realized the cooling to motor from water inlet 2 input backs.This spirality channel has certain cooling effect, but its heat exchange area is subjected to the restriction of square-section, and cooling effect is under some influence, and has restricted the further raising of water-cooled machine power and torque.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of housing that is used to improve the water-cooled machine of cooling effect, this housing overcomes the defective of the traditional water cool electric machine type of cooling, under equal volume and weight, further improve the cooling effect of water-cooled machine, effectively improved the power and the torque of water-cooled machine.
For solving the problems of the technologies described above, the housing that the utility model is used to improve the water-cooled machine of cooling effect comprises the electric machine casing body, along the circumferential direction be provided with spirality channel in the described electric machine casing body wall, described spirality channel starting point is that water inlet, terminal point are delivery port, and the cross section of described spirality channel both sides in opposite directions is waveforms.
Because being used to improve the housing of the water-cooled machine of cooling effect, the utility model adopted technique scheme, the housing that is this water-cooled machine comprises the electric machine casing body, along the circumferential direction be provided with spirality channel in the described electric machine casing body wall, described spirality channel starting point is that water inlet, terminal point are delivery port, and the cross section of described spirality channel both sides in opposite directions is waveforms.This housing overcomes the defective of the traditional water cool electric machine type of cooling, under equal volume and weight, has further improved the cooling effect of water-cooled machine, has effectively improved the power and the torque of water-cooled machine.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is a traditional water cool electric machine housing spiral water channel schematic diagram;
Fig. 2 is a traditional water cool electric machine housing spiral water channel schematic cross-section;
Fig. 3 is used to improve the schematic diagram of the water-cooled machine housing of cooling effect for the utility model;
Fig. 4 is this water-cooled machine housing spiral water channel schematic diagram;
Fig. 5 is the schematic cross-section of spirality channel among Fig. 4.
Embodiment
As Fig. 3, Fig. 4 and shown in Figure 5, the housing that the utility model is used to improve the water-cooled machine of cooling effect comprises electric machine casing body 5, along the circumferential direction be provided with spirality channel 1 in described electric machine casing body 5 walls, described spirality channel 1 starting point is that water inlet 2, terminal point are delivery port 3, and the cross section of described spirality channel 1 both sides in opposite directions is waveforms 6.
This housing along the circumferential direction is provided with spirality channel in the wall of enclosure body, this spirality channel is a waveform along the both sides in opposite directions of circumference, thereby has increased the heat exchange area of interior cooling water of spirality channel and enclosure body, improves the cooling effect of motor.In the electric machine casing of equal volume, adopt the heat exchange area of this spirality channel bigger by 5 ~ 10% than the heat exchange area of the spirality channel in traditional rectangular cross section, thereby effectively improved the cooling effect of water-cooled machine, help the raising of water-cooled machine power and torque, and improved stock utilization and cost performance that motor is made, more be applicable to as vehicle-mounted grade the place that has certain requirements, space.
