[0002] With the increasing demands of cutting, grooving, and drilling equipment, it is often necessary to upgrade the motors in these machines. Nowadays, brushless motors are used in these machines. In order to control the motor, it is usually connected to a motor controller. However, the motor controller is prone to overheating after prolonged use. If the motor controller is in a high-temperature state for a long time, the internal chip of the controller may burn out, ultimately causing the motor to be damaged and unusable.

[0003] The traditional cooling method for motor controllers involves setting up a heat dissipation layer on the controller body, typically using a finned structure for air cooling. This traditional cooling method has poor cooling efficiency and cannot effectively protect the controller chip.

[0004] Therefore, in order to ensure the normal use of mechanical equipment and avoid the burning out of control components, a combination of air cooling and water cooling may be used to optimize the heat dissipation of the controller.

[0005] However, with water-cooled controllers, there is a risk of the water cooling channel being connected to the control components, and the coolant may leak, affecting the lifespan of the control components or the controller.

[0006] Therefore, in order to improve or solve at least one of the above problems, it is necessary to optimize the heat dissipation structure of the existing controller.

[0033] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0034] A heat dissipation structure for a controller includes a heat dissipation base 1; heat dissipation fins 2 are provided on the heat dissipation base 1; a connection part for connecting to control components is provided on the heat dissipation base 1; a water cooling channel 3 is provided on the heat dissipation base 1; the water cooling channel 3 and the connection part are staggered.

[0035] This invention optimizes the heat dissipation effect of the controller by using the heat dissipation base 1, heat dissipation fins 2 and water cooling channel 3 together, which helps to extend the service life of the control components.

[0036] The heat dissipation structure for the controller disclosed in this utility model mainly includes a heat dissipation base 1; the heat dissipation base 1 is provided with heat dissipation fins 2; the heat dissipation base 1 and the heat dissipation fins 2 are generally made of aluminum alloy, but other materials can be selected as needed, as long as the heat dissipation effect can be guaranteed, it is theoretically feasible. At the same time, in this utility model, the heat dissipation base 1 is provided with a connecting part for connecting with control components; the setting of the connecting part facilitates the connection between the control components and the heat dissipation base 1; that is, it facilitates the installation and assembly of the control components on the heat dissipation base 1.

[0037] In addition, the heat dissipation base 1 described in this utility model is provided with a water cooling channel 3; the water cooling channel 3 is an internal channel structure, which facilitates subsequent use in conjunction with the water supply mechanism; and facilitates water supply and water outlet operations to the heat dissipation structure.

[0038] Meanwhile, in this utility model, the water-cooling channel 3 and the connecting part are required to be staggered. By staggering the water-cooling channel 3 and the connecting part, this utility model can avoid the connection between the connecting part and the water-cooling channel 3, thereby avoiding the risk of water leakage at the connection between the control component and the heat dissipation base 1.

[0039] The staggered distribution here mainly requires that the water-cooling channel 3 and the connecting part are not interconnected, and the two are distributed at intervals; to prevent the coolant in the water-cooling channel 3 from flowing to the connecting part.

[0040] In addition, in this utility model, the heat dissipation fins 2 are provided on the heat dissipation base 1 to increase the heat dissipation area for heat dissipation; the connecting part is used to connect the control components to the heat dissipation base 1, so that the control components can dissipate heat with the help of the heat dissipation base 1; the water cooling channel 3 is also provided on the heat dissipation base 1, and is staggered from the connecting part. The staggered distribution may be for reasonable layout, to avoid mutual interference, and to give full play to their respective heat dissipation and connection functions; in addition, it can also prevent the coolant in the water cooling channel 3 from entering the connecting part; thereby avoiding the influence of the coolant on the control components.

[0041] Furthermore, in this invention, the water-cooling channel 3 includes a main channel 4, which is an arc-shaped groove. The arc-shaped groove design of this invention is to better guide the flow of cooling water or coolant and optimize the heat dissipation effect. In addition, through the above design, the turbulence and voids of the coolant can be reduced: the arc-shaped groove design makes the coolant flow more smoothly in the channel, reducing the generation of turbulence and voids. In addition, the arc-shaped groove design increases the heat exchange area: the shape of the arc-shaped groove increases the contact area between the coolant and the heat dissipation substrate 1, thereby improving the heat exchange efficiency.

[0042] With the same channel cross-sectional area, the arc-shaped groove can provide more heat exchange surface, allowing heat to be transferred from the heat dissipation substrate 1 to the coolant more quickly and then carried away.

[0043] Improving heat distribution uniformity: The arc-shaped groove design helps improve the temperature distribution uniformity on the heat dissipation substrate 1. Because the coolant flows more smoothly in the arc-shaped groove, heat can be transferred more evenly to the entire heat dissipation substrate 1, avoiding local overheating, which is especially important for controlling the stable operation of components.

[0044] The curved surface structure of the arc-shaped groove can more effectively disperse stress and reduce stress concentration. The pressure and thermal stress generated during the flow of coolant will be evenly distributed on the wall of the arc-shaped groove, thereby reducing the risk of structural damage caused by stress concentration and improving the reliability and service life of the heat dissipation structure. It also simplifies the manufacturing process: the arc-shaped groove is relatively simple to manufacture and the manufacturing cost is relatively low; this helps to reduce the manufacturing difficulty and cost of the heat dissipation structure and improve production efficiency.

[0045] Furthermore, in this utility model, the main channel 4 is provided through the heat dissipation base 1; the through-type design allows cooling water or coolant to flow smoothly inside the heat dissipation base 1, more fully carrying away heat and improving heat dissipation efficiency.

[0046] Furthermore, in this utility model, the main channel 4 is distributed at the end of the heat dissipation base 1 away from the heat dissipation fins 2. This layout takes into account that the heat dissipation fins 2 mainly dissipate heat through air convection, while the main channel 4 uses water cooling. The two are arranged separately to avoid mutual interference in heat dissipation effect, and at the same time, targeted heat dissipation can be carried out according to the heat dissipation needs of different positions of the heat dissipation base 1.

[0047] Furthermore, in this utility model, the cross-sectional shape of the main channel 4 is a part of a circle, and the arc length accounts for a proportion of the entire circumference ranging from one-half to three-quarters. This specific cross-sectional shape design is to ensure the normal flow of cooling water or coolant while making reasonable use of the internal space of the heat dissipation base 1.

[0048] In addition, the above design provides more physical space above the main channel 4, which facilitates the installation and fixing of subsequent fasteners; at the same time, it ensures the normal flow of coolant as much as possible.

[0049] Furthermore, in this invention, the heat dissipation substrate 1 is connected to multiple control components; each control component is connected to the heat dissipation substrate 1 through a connecting part; the connecting part serves as a good bridge, facilitating the connection between the heat dissipation substrate 1 and the control components. In this invention, the connecting part includes a connecting hole 6 on the heat dissipation substrate 1, and a fastener for installing the control component is provided in the connecting hole 6; the fastener can be a screw or a bolt; subsequently, the fastener passes through the control component and connects to the corresponding connecting hole 6, thereby realizing the installation and connection of the control component on the heat dissipation substrate 1.

[0050] Meanwhile, in this utility model, each of the fasteners and / or connecting holes 6 is spaced apart from the main channel 4; this arrangement can avoid the connection between the control components and the heat dissipation base 1 and the main channel 4 being spaced apart, that is, the connection point between the control components and the heat dissipation base 1 and the main channel 4 are not interconnected, thereby preventing the coolant in the main channel 4 from flowing out or overflowing and affecting the service life of the controller.

[0051] Furthermore, in this utility model, the distance between the main channel 4 and the connecting hole 6 closest to the main channel 4 is not less than 1mm; this setting facilitates the processing and production of the main channel 4 and the connecting hole 6; based on the above design, normal and stable connection function can be guaranteed while ensuring heat dissipation.

[0052] Furthermore, in this utility model, the water cooling channel 3 also includes an end countersunk hole 5 disposed on the heat dissipation base 1; the end countersunk hole 5 is connected to the main channel 4; the end countersunk hole 5 in this utility model facilitates the connection with the external connector 7 and the connection with the liquid supply or liquid outlet pipe. The end countersunk hole 5 is generally designed as a circular countersunk hole and is provided with an external thread inside to facilitate the subsequent threaded connection with the external connector 7.

[0053] Furthermore, in this utility model, the main channel 4 extends along the length of the heat dissipation substrate 1; the extension direction of the main channel 4 is the same as the extension direction of the heat dissipation fins 2; based on the above design, it is to enable the heat dissipation fins 2 and the water cooling channel 3 to cooperate with each other during heat dissipation, forming a more effective heat dissipation path and jointly improving the heat dissipation effect; at the same time, it facilitates subsequent demolding production.

[0054] A controller assembly includes a heat dissipation structure for the controller; multiple control components are respectively arranged on both sides of a heat dissipation base 1 in the heat dissipation structure; two control components distributed opposite each other on both sides of the heat dissipation base 1 can be connected by the same fastener; the fastener can penetrate the heat dissipation base 1; by connecting the control components through the heat dissipation base 1 with the fastener, both heat dissipation and fixed connection of the control components are achieved; at the same time, two control components can be connected by one fastener, which can reduce the number of fasteners used.
