Description

Technical Field

[0001] This utility model relates to a heat dissipation design, specifically a heat sink for a motor. Background Technology

[0002] Motors are widely used in various industrial and household products. However, during operation, whether in the rotating components (such as stator, bearings, rotor, and spindle) or the control components (such as load, transformer, and capacitor), the motor will generate heat due to operation or power consumption.

[0003] There are many reasons why a motor might overheat, such as inherent motor losses like iron losses, copper losses, mechanical losses, and eddy current losses. Improper use or operation can also cause overheating, such as overload, excessive operating time, frequent starts and stops, excessive voltage, ambient temperature, and improper capacitor matching. The most common cause is the generation of heat due to impedance when current flows through the coils. This heat then travels through components around the coils, such as the stator, where heat conduction affects other components. For example, a high-speed spindle generates heat due to rolling friction in the bearings. This heat not only interferes with the operation of motor components but also, because it originates within the motor itself, tends to accumulate inside the motor housing. Furthermore, the controller, which is integrally mounted on the motor housing, cannot effectively dissipate heat. The combined effect of this high temperature and the controller's own heat generation can easily cause rapid damage to the controller, significantly reducing the motor's lifespan. This issue requires improvement.

[0004] Furthermore, due to existing motor structural design factors, heat dissipation is achieved through passive cooling (such as heat sink fins) or active cooling (such as cooling fans). If heat sink fins are used, in addition to increased material costs (such as copper and aluminum), the motor with these fins requires a well-ventilated environment for effective heat exchange between the fins and the outside air to achieve a cooling effect, thus limiting its effectiveness. Furthermore, if a cooling fan is added to the motor, besides requiring extra space for the fan, the cost of adding the fan is high, and it consumes additional electricity. Since the cooling fan cools by blowing outside air, dust accumulation in the air over time can affect its cooling effect. Therefore, both existing methods using cooling fans and heat sink fins require subsequent cleaning and maintenance; otherwise, the actual cooling efficiency will be reduced, leading to excessively high maintenance costs, which needs improvement. Utility Model Content

[0005] Therefore, the purpose of this invention is to provide a heat sink for a motor that achieves low cost, provides rapid heat dissipation for the controller, and greatly extends the service life of the motor.

[0006] Therefore, this utility model is used for a radiator for a motor. The motor includes a motor body with a drive unit and a controller for controlling the operation of the drive unit. The motor body is connected to a connecting pipe for liquid flow, and the liquid is output through the connecting pipe under the action of the drive unit. In particular, a radiator is provided on the connecting pipe, and the radiator is provided with a support seat for positioning the controller, so that the heat generated by the controller is conducted out through the support seat and then exchanged with the liquid flowing through the connecting pipe and the radiator. Therefore, the controller can be cooled in a low-cost, simple and fast way, which greatly improves the service life of the motor.

[0007] As a further improvement of this utility model, the connecting pipe is formed with at least two connecting holes.

[0008] As a further improvement of this utility model, the connecting pipe and the bearing base are integrally formed.

[0009] As a further improvement of this utility model, the motor body with the drive unit can be replaced by a pump. Attached Figure Description

[0024] A: Liquid Detailed Implementation

[0025] The foregoing and other technical contents, features and effects of this utility model will become clear in the following detailed description of the preferred embodiments with reference to the accompanying drawings.

[0026] See Figure 1 This utility model relates to a preferred embodiment of a radiator 3 for a motor 4. In this embodiment, the motor 4 includes a motor body 41 with a drive unit and a controller 42 for controlling the operation of the drive unit. The controller 42 is mainly used to control the operation of the drive unit and is a control circuit consisting of a combination of components such as a frequency converter and a starter. The motor body 41 is connected to a connecting pipe 5 for the flow of liquid A. Liquid A is output through the connecting pipe 5 under the action of the drive unit. One end of the connecting pipe 5 is connected to a supply source, such as an external water source such as tap water, groundwater, or industrial wastewater, or a source that can transport oil. These are all considered supply sources in this embodiment. In this embodiment, the transport of water A is used as an example for explanation.

[0027] Continuing from the foregoing, in this embodiment, a heat sink 3 is provided on the connecting pipe 5. The heat sink 3 has a hollow connecting pipe 31 connected to the connecting pipe 5, and a support base 32 disposed on the connecting pipe 31 and positioned by the controller 42. The connecting pipe 31 and the support base 32 can be integrally formed, or they can be connected and fixed together. That is, when the connecting pipe 31 and the support base 32 can be integrally formed, refer to [reference needed]. Figure 2 The connecting pipe 31 and the support base 32 are made of metal, so the heat generated by the controller 42 can be discharged through the connecting pipe 31 and the support base 32. The connecting pipe 31 and the support base 32 are connected and fixed in place. (See attached document for details.) Figure 3 The connector 31 and the support base 32 are made of metal, so the heat generated by the controller 42 can be discharged through the connector 31 and the support base 32, or refer to [reference needed]. Figure 4The support base 32 is made of metal, while the connecting pipe 31 is made of plastic. The support base 32 extends into the connecting pipe 31 and comes into contact with the liquid A flowing within the connecting pipe 31. Regardless of the type, the heat generated by the controller 42 is conducted away through the support base 32. This embodiment will be described below. Figure 2 The example shown is used to illustrate this.

[0028] See Figure 1 , Figure 2 The connector 31 has at least two connecting holes 311, one of which allows water from the supply source to enter the connector 31, and then the water A flows out through the other connecting hole 311. In this embodiment, the connector 31 has at least three connecting holes 311, one of which allows the water A to be input into the connector 31, and then the water A flows out through the other two connecting holes 311, so that the connector 31 can be used as a general three-way valve water pipe.

[0029] See Figure 1 In this embodiment, when the motor 4 is installed, the motor body 41 and the controller 42 are separately configured. That is, the motor body 41 is connected to the connecting pipe 5, and the connecting pipe 5 is connected to the serial connector 31. The support base 32 is used for positioning the controller 42. Therefore, when the drive unit inside the motor body 41 is driven, the heat generated by the drive unit is only transferred to the motor body 41 and dissipated through the motor body 41 and the outside air. This heat will not affect the controller 42. Furthermore, the heat generated by the controller 42 itself can be selectively installed on the existing water supply A connecting pipe 5, and the serial connector 31 is connected to the connecting pipe 5, so that the water supply A in the connecting pipe 5 can flow into the serial connector through one of its connecting holes 311. After passing through pipe 31, the water flows out through another connecting hole 311. The heat generated by the controller 42 can be conducted through the support 32 to the connecting pipe 31, where it exchanges heat with the water A. Thus, when the heat generated by the controller is delivered to the support 32 and the connecting pipe 31, it can exchange heat with the water A and the heat on the connecting pipe 31 and the support 32, thereby removing the heat from the connecting pipe 31 and the support 32. This allows the connecting pipe 31 and the support 32 to dissipate heat quickly, preventing the controller 42 from burning out or being damaged due to the heat source. With the design of this radiator 3, it can be used to quickly connect to the existing connecting pipe 5 without the need for a cooling fan or cooling fins, achieving rapid heat dissipation at low cost.

[0030] See Figure 5In another preferred embodiment of the present invention, the motor body 41 with the drive unit of the previous embodiment is replaced by a pump, while the controller 42 is still located on the support platform 32. The motor body 41 will be replaced by a pump in this embodiment. The pump can be connected to the connecting pipe 5. After the pump is actuated, the pump drives the liquid A in the connecting pipe 5 to flow. Therefore, when the radiator 3 is located on the connecting pipe 5, the heat generated by the pump operation controlled by the controller 42 can be conducted to the connecting pipe 31 through the support platform 32. During the process of the liquid A flowing through the connecting pipe 31, heat exchange occurs with the heat on the connecting pipe 31, thereby achieving the effect of low cost and rapid heat dissipation.

[0031] In summary, the present invention is a radiator for motors, which mainly separates the motor controller from the motor body and places it on the radiator. The radiator can exchange heat with the liquid flowing in the connecting pipe to achieve a reliable cooling effect for the controller, thereby achieving low cost and rapid heat dissipation.

[0032] The above description is only for illustrating preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Any simple equivalent changes and modifications made in accordance with the scope of the present utility model patent application and the contents of the utility model specification should still fall within the scope of the present utility model patent.
