Description

Technical Field

[0001] This application relates to the field of controllers, and more particularly to a water-cooled controller. Background Technology

[0002] Currently, controllers generally use air cooling. However, for some controllers, air cooling is insufficient to meet heat dissipation requirements when the ambient temperature is high. For example, in high-voltage DC motor applications (such as high-power industrial motor equipment, grooving machines, ring saws, and cutting machines), the motor controller, as a core component, generates a large amount of heat during power conversion. If this heat cannot be dissipated in time, it will cause the temperature of the internal electronic components (such as IGBT modules) to become too high, affecting the motor's operating efficiency and reliability, and even shortening the lifespan of components, leading to malfunctions. Traditional heat dissipation methods (such as simple air cooling) are limited by their heat dissipation efficiency and cannot meet the heat dissipation requirements of high-voltage DC motor controllers under high power density. Therefore, this application was developed. Utility Model Content

Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0034] Example 1: This embodiment discloses a water-cooled controller. (Refer to...) Figures 1-5As shown, the water-cooled controller includes a housing 1 and a water-cooled radiator 5 disposed inside the housing 1. The water-cooled radiator 5 has a coolant chamber 59 internally. Pipe connectors 6, communicating with the coolant chamber 59, are located at opposite ends of the water-cooled radiator 5. The pipe connectors 6 extend out of the housing 1 to connect with an external water source, allowing coolant to enter the coolant chamber 59 of the water-cooled radiator 5 inside the housing 1 through one pipe connector 6 to cool the internal environment of the housing 1. Then, the coolant flows out of the housing 1 through the other pipe connector 6. This design allows for the recycling of cooling water. By adopting the above technical solution, water cooling of the controller is achieved. Compared with conventional air-cooled controllers, this method offers faster cooling speed and higher efficiency, rapidly reducing the internal temperature of the controller and ensuring the normal operation of the internal electronic components, thus meeting the heat dissipation requirements of high-voltage DC motor controllers under high power density.

[0035] In this embodiment, to facilitate the assembly and disassembly of the pipe connector 6 and the water-cooled radiator 5, such as Figure 5 As shown, the water-cooled radiator 5 has coolant holes 56 at both opposite ends, and the pipe joint 6 is sealed and plugged into or screwed into the coolant holes 56.

[0036] Preferred, such as Figure 1 and Figure 2 As shown, the housing 1 has a pair of spaced and parallel mounting plates 2 inside. The space between the mounting plates 2 is configured to accommodate the water-cooled radiator 5 and fix the water-cooled radiator 5 to the mounting plates 2. By adopting the above technical solution, it is convenient to install the water-cooled radiator 5 inside the housing 1, and it is also convenient to install the electronic components of the controller inside the housing 1 onto the mounting plates 2. Since the mounting plates 2 are in direct contact with the water-cooled radiator 5, the design of not directly contacting the electronic components with the mounting plates 2 results in higher cooling efficiency and faster heat dissipation.

[0037] Preferred, such as Figures 3-5 As shown, the water-cooled radiator 5 includes a heat dissipation base plate 51 and a pair of spaced and parallel positioning plates 53. The pair of positioning plates 53 extend into the receiving space 4 and are fixedly connected to the mounting base plate 2, thereby enabling direct contact between the mounting base plate 2 and the positioning plates 53, facilitating the installation of the water-cooled radiator 5 inside the housing 1. The pair of positioning plates 53 are spaced apart, thus forming a heat dissipation groove 55 between the pair of positioning plates 53. The heat dissipation groove 55 facilitates air circulation and improves heat dissipation efficiency.

[0038] In this embodiment, as Figures 3-5As shown, the heat dissipation base plate 51 and a pair of positioning plates 53 are integrally connected to the portion extending out of the receiving space 4. The outer surface of the heat dissipation base plate 51 is constructed with multiple heat dissipation components, at least some of which are detachably and fixedly connected to the inner wall of the housing 1. This design ensures that the water-cooled radiator 5 is stably installed inside the housing 1 and does not easily shake. Correspondingly, the mounting base plate 2 and the positioning plates 53 can adopt common quick and detachable connection methods between components, such as plug-in or snap-fit ​​connections. Conversely, if the heat dissipation components do not contact the inner wall of the housing 1, the mounting base plate 2 and the positioning plates 53 must be reliably connected, such as by bolts, to ensure that the water-cooled radiator 5 is installed stably and reliably and does not shake. Figure 2 As shown, the mounting plate 2 is provided with fasteners 3, which are detachably and fixedly connected to the positioning plate 53 and the mounting plate 2. Common fasteners 3 are bolts. Correspondingly, the positioning plate 53 and the mounting plate 2 are provided with mounting holes 54 to accommodate the fasteners 3. Figure 4 As shown, fastener 3 facilitates the disassembly and assembly of positioning plate 53 and mounting base, and ensures the stable installation of water-cooled radiator 5.

[0039] In this embodiment, the coolant cavity 59 is located inside the heat dissipation substrate 51 and the heat dissipation component, so the water-cooled radiator 5 designed in this way has efficient and fast heat dissipation.

[0040] Specifically, such as Figures 1-5 As shown, the heat dissipation component is a heat sink 52, with multiple heat sinks 52 distributed on opposite sides of the heat dissipation substrate 51. The heat sinks 52 are perpendicular to the sides of the heat dissipation substrate 51, and adjacent heat sinks 52 are spaced apart and arranged parallel to each other. By adopting the above technical solution, the heat dissipation efficiency of the heat dissipation component is maximized.

[0041] In this embodiment, further, such as Figures 3-5 As shown, the width of the heat sink 52 gradually decreases from the middle of the side of the heat dissipation substrate 51 towards both ends in the width direction, and the coolant hole 56 is located in the middle of the side of the heat dissipation substrate 51. This design reduces the resistance of the heat sink 52 to the airflow inside the housing 1, facilitates the airflow circulation inside the controller housing 1, and improves heat dissipation efficiency.

[0042] In this embodiment, a leakage current detection device is further provided inside the housing 1 to detect whether the water-cooled radiator 5 is energized. A common leakage current detection device is a leakage current sensor. By adopting the above technical solution, the safe operation of the controller is ensured, and leakage current is prevented from causing the coolant in the coolant chamber 59 to become energized.

[0043] In this embodiment, the housing 1 is equipped with power devices, such as IGBT modules. The power devices are the source of heat generation in the controller. Therefore, fixing the power devices to the mounting plate 2 can dissipate heat from the power devices more quickly and improve heat dissipation efficiency.

[0044] Example 2: The difference between this embodiment and Embodiment 1 is as follows: Figure 6 As shown, multiple heat dissipation strips 58 are symmetrically arranged on both sides of the heat sink 52. The multiple heat dissipation strips 58 are spaced apart and arranged parallel to each other along the width direction of the heat sink 52. This design further increases the heat dissipation area and improves heat dissipation efficiency.

[0045] Example 3: The difference between this embodiment and Embodiment 1 is as follows: Figure 7 As shown, the heat dissipation component is a heat dissipation column 57. The heat dissipation column 57 is perpendicular to the side of the heat dissipation substrate 51 away from the positioning plate 53. The height of the heat dissipation column 57 gradually decreases from the middle of the side of the heat dissipation substrate 51 towards both ends in the width direction. Adjacent heat dissipation columns 57 are spaced apart and parallel to each other. With this design, compared with the heat dissipation fin 52, the heat dissipation column 57 has less resistance, which is more conducive to the flow of surrounding air and improves heat dissipation efficiency.
