Definitions
- the present invention relates to a drive device using an electric motor as a power source, and more particularly, to a cooling technique in a drive device for an electric vehicle or a hybrid drive device.
- an electric motor When an electric motor is used as a drive source for a vehicle, the electric motor requires a control device (inverter for an AC motor) for its control.
- a control device such as an indexer is connected to the electric motor by a power cable, and thus can be arranged at an appropriate position separately from the electric motor.
- An integrated arrangement may be adopted.
- the heat resistance temperature of the control device is lower than the heat resistance temperature of the motor. Therefore, when the control device is integrated with the electric motor as described above, some means for interrupting the direct heat transfer from the electric motor to the control device is required to protect the control device. In addition, the temperature of the control device rises due to the heat generated by its own element, so it needs to be cooled to keep it below the heat resistance temperature.
- a motor integrated with a control device in which a groove is formed on the outer periphery of the stator body of the motor, and the open side of the groove is closed with a bottom plate on which the module of the control device is mounted to provide a cooling path has been published internationally. Proposed in No. 98/2883 33 pamphlet. In this technique, a cooling flange extending into a groove on the bottom plate side is formed.
- the tip of the cooling flange is separated to some extent from the bottom of the groove of the stator pod, and the cooling fluid flows through the gap between them in order to prevent heat from the stator body from being transmitted to the module side via the cooling flange. It is necessary to ensure the heat insulation effect. If the gap is widened as described above, the effect of the cooling flange as a flow path guide decreases.
- the present invention has been devised based on such conventional technology, and in a drive device in which an inverter is integrated with a motor, the heat transfer from the motor to the inverter is suppressed while the heat transfer is restricted in a limited cooling space.
- the main purpose is to secure the maximum heat dissipation area for the refrigerant.
- another object of the present invention is to improve the cooling performance by promoting the flow of the refrigerant by the heat radiating means in the cooling space. Disclosure of the invention
- the present invention provides a drive device comprising: an electric motor; a drive device case accommodating the motor; an impeller for controlling the electric motor; and a refrigerant flow path for cooling the impeller.
- a heat sink integrated with the substrate defines a space in a portion facing the drive device case and is attached to the drive device case. The space is communicated with a coolant flow path, and the heat sink is driven by the heat sink.
- a heat sink side fin extending into the space toward the device case; the drive device case including a drive device case fin extending into the space toward the heat sink;
- the main feature is that the heat sink side fin and the drive device case side fin are separated from each other.
- the heat sink side fins and the drive device case side fins cooperate to generate a common refrigerant flow pattern in the space.
- a common coolant flow using the fins is generated on both the heat sink side and the drive device case side in the space, it is possible to prevent stagnation due to interference of the coolant flow in the space.
- the heat sink side fins and the drive unit case side fins may be the same type of fins or different types of fins.
- the heat sink side fins and the drive device case side fins have the same arrangement, and the desired flow pattern without stagnation due to interference of flow in the space can be generated. Can be.
- both the heat sink side fins and the drive device case side fins may be pin-shaped fins.
- the flow path resistance can be significantly reduced as compared with the configuration in which the fluid flow in the space is guided by the rib-shaped fins. Therefore, according to this configuration, the pressure loss in the flow path can be reduced, and the impeller integrated with the drive device can be cooled with low energy consumption.
- one of them may be made of a rib-like fin and the other may be made of a pin-like fin.
- the heat sink side fins and the drive unit case side fins are both rib-shaped fins. Since the flow path resistance is reduced on the side of the fins, the flow path resistance in the entire space can be reduced.
- the heat sink side fin and the drive device case side fin cooperate with each other to substantially cross the space with a small gap therebetween.
- this configuration it is possible to generate substantially one cooling fluid flow without stagnation due to flow interference in the space while avoiding heat transfer due to direct contact between the heat sink side fin and the drive case fin. Can be.

- FIG. 1 schematically illustrates a cooling system of a drive device to which the present invention is applied.
- This device includes an electric motor (not shown), a drive device case 2 for housing the electric motor, an inverter 3 for controlling the electric motor, and a refrigerant flow path 4 for cooling the inverter 3.

- the outlet 42 of the radiator 42 is connected to the inlet 42 1 side of the radiator 42 via the port 44, and the inlet side channel 45 of the water pump 41 is connected to the outlet 42 of the radiator 42. Therefore, in this refrigerant circulation path, the cooling water as the refrigerant is heated by absorbing heat from the module of the inverter 3 after being sent out from the water-pump 41 and flowing through the space inside the heat sink 53. Then, it is sent to the radiator 42 via the return flow path 44 and cooled by heat release to the air, and is returned to the water pump 41 to repeat the circulation which completes one cycle.
- This refrigerant circulation path may be a flow path that passes through the inside of the drive device case 2 for further cooling, for example, in the middle of the return flow path 44.

- Space R 1 This space R1 constitutes a space on the drive device case 2 side of the space R defined in a portion where the heat sink 53 is opposed to the drive device case 2.
- the heat sink 53 is formed as a separate member from the substrate of the impeller 3, and is constituted by the bottom wall 53 of the impeller case 5.
- the outer shape of the impeller case 5 is framed from the bottom wall 53.
- the case is provided with a peripheral wall 54 extending upward so as to surround the inside of the case, and the inside of the case is a space for accommodating the impeller 3.
- the module constituting the impeller 3 is tightly fixed to the bottom wall 53 of the impeller case 5 which has been flattened so as to bring the module into close contact and to be integrated by appropriate means.
- the upper opening of the impeller case 5 is covered with a force par 7.
- a space R2 defined by a peripheral wall 55 extending downward so as to surround the outer shape of the inverter case 5 in a frame shape.
- the space R2 forms a space on the heatsink 53 side of the space R defined by the heatsink 53 in a portion facing the drive device case 2.

- the heat sink 53 has a number of heat sink side fins 56 extending into the space toward the drive case 2, and the drive case 2 has a space inside the space toward the heat sink 53.
- Such a configuration in which the two fins are separated from each other can be realized by providing a gap at the tip of the fins arranged at the same position, or by arranging the fins at different positions. In any of these configurations, the heat sink side fins 56 and the drive unit case side fins 22 cooperate to generate a common refrigerant flow pattern in the space.
- FIG. 4 shows the arrangement pattern of the heat sink side fins 56 and the drive unit case side fins 22 according to the first embodiment.
- the bottom surface of the inverter case 5 and the drive unit case 2 The mounting surfaces are shown in a schematic plane in which they are arranged on the same plane.
- the heat sink side fins 56 and the drive device case side fins 22 are pin-shaped fins having the same pattern and are arranged at regular intervals.
- both fins have the same arrangement position in the space R
- the heat sink side fins 56 and the drive unit case side fins 22 are separated from each other with a small gap therebetween. However, they are arranged in the same number so that they cooperate to substantially cross the space R.
- the fluid flowing through the gap between the fins is insulated by the heat insulating layer.
- the flow path resistance can be greatly reduced as compared with the configuration in which the fluid flow in the space is guided by the lip-shaped fins. Therefore, according to this configuration, the pressure loss in the flow path can be reduced, and thereby the inverter 3 integrated with the driving device can be cooled together with the driving device case 2 with little energy consumption.
- the heat sink side fins 56 and the drive device case side fins 22 are both pin-shaped fins, and both fins are arranged at regular intervals with respect to the plane of the space.
- the number of the drive device case-side fins 22 is smaller than that of the heat sink-side fins 56, and the arrangement density is coarse.
- the heat exchange area of the fins 56 on the heat sink side is increased, so that the heat sink 53 is cooled more strongly. Therefore, a temperature gradient corresponding to the heat resistant temperature of each of the impeller 3 and the electric motor 1 can be generated in the space due to the difference in the cooling capacity.
- the pressure loss of the entire space R can be reduced by the lower the arrangement density of the drive device case-side fins 22, and the energy consumption can be further reduced.

- the heat sink side fins 56 and the drive device case side fins 22 are the same type of rib-like fins, and both fins are equally spaced extending from the fluid inlet to the outlet.
- the number of the drive device case-side fins 22 is smaller than that of the heat sink-side fins 56.
- the heat sink 5 side is cooled more strongly, and the A temperature gradient corresponding to the heat-resistant temperature of each of the motor 3 and the electric motor 1 can be generated in the space.
- the pressure loss of the space R as a whole can be reduced by the lower the arrangement density of the drive device case-side fins 22.
- the heat sink side fins 56 and the drive device case side fins 22 are configured such that one of the drive device case side fins 22 is formed of a rib-like fin and the other heat sink side fin 22 is formed of a rib-like fin.
- the side fins 56 are constituted by pin-shaped fins. If one of the fins 22 and 56 has a lip shape and the other has a pin shape, the flow in the space on the side where the rib fins are arranged is disadvantageous in terms of pressure loss. In each part of the space, it is advantageous to forcibly guide and uniform the flow, and the flow in the space on the side where the pin-shaped fins are arranged is advantageous in that pressure loss is reduced.
- the fins in both spaces are
- the flow resistance of the flow path in the space can be reduced as a whole as compared with the case where the fins in both spaces are used, and the flow characteristics can be improved as compared with the case where the fins in both spaces are both pin-shaped fins .

- the space R is defined by the drive unit case 2, the inverter case 5, and the heat sink 33 of the inverter module.
- the present invention has been described in detail based on the six embodiments. However, the present invention is not limited to these embodiments, and various concrete configurations may be changed within the scope of the claims. Can be implemented.
