Description

Technical Field

[0001] The utility model relates to a heat dissipation structure, in particular to a water channel heat dissipation structure of a high-pressure controller shell. Background Art

[0002] During operation, the internal components of a high-voltage controller generate significant heat, which must be effectively dissipated to ensure stable operation. To achieve efficient heat dissipation, a specialized housing structure is designed with an integrated cooling water flow structure. This circulating cooling water effectively absorbs and removes the internal heat, achieving precise and efficient heat dissipation and ensuring the continued reliable operation of the high-voltage controller.

[0003] Currently, most shell heat dissipation adopts river-type heat dissipation structure, such as Figure 1 As shown. This structure is simple in layout and is easy to implement for both the initial hand-made workpiece and the subsequent casting. However, due to the large number of bends in this structure, heat dissipation will be greatly affected, as shown below:

[0004] 1. Uneven heat dissipation efficiency: Due to the winding design in the structure, the speed and flow rate of cooling water may be uneven when flowing through different areas. This may result in significant heat dissipation in some areas, while other areas may have poor heat dissipation due to insufficient water flow, forming "hot spots" and affecting the overall heat dissipation performance.

[0005] 2. Increased maintenance costs: The complex curved structure is prone to accumulation of dirt and impurities during long-term use, especially at the corners of the waterway. These deposits will further hinder the water flow and reduce the heat dissipation efficiency. Therefore, more frequent cleaning and maintenance are required, increasing maintenance costs and time.

[0006] 3. Limited design flexibility: River-style heat dissipation structures are often based on fixed water flow paths, which to some extent limits the layout and design flexibility of other components inside the housing. To meet heat dissipation requirements, it may be necessary to sacrifice design space for other key performance or functions.

[0007] 4. Increased energy consumption: Due to the large flow resistance caused by many bends, in order to maintain sufficient cooling water flow, it may be necessary to increase the power of the water pump, thereby increasing the energy consumption of the entire system. In the long run, this will increase energy consumption and operating costs;

[0008] 5. Noise problem: The increased pump power and complex water flow path may cause greater noise during system operation, which will have an adverse impact on the equipment's operating environment and user experience;

[0009] 6. Low space utilization: The river-type heat dissipation structure usually requires a larger space to arrange the water channel, which to a certain extent reduces the space utilization inside the shell and limits the integration and layout optimization of other functional components.

[0010] Based on this, it is necessary to develop a water channel heat dissipation structure for the high-pressure controller housing to effectively solve the above problems. Summary of the Invention

The 6 columnar ribs are divided into 2 groups. The 2 groups are arranged parallel to the third partition plate and are arranged at intervals. Except for the second group in the second heat dissipation area, in each transversely arranged columnar rib, two adjacent columnar ribs and their vertically adjacent columnar ribs form an isosceles triangle. The base length of the isosceles triangle is 16 mm, and the length of the two sides is 10 mm.

[0016] The first heat dissipation area of ​​the second heat dissipation channel is close to the water inlet and consists of 7 columnar ribs. The 7 columnar ribs are divided into 2 groups. The 2 groups are arranged in parallel along the direction of the first partition plate and are arranged at intervals. The second heat dissipation area connects the first heat dissipation area and the third heat dissipation area and consists of 39 columnar ribs. The 39 columnar ribs are divided into 4 groups. They are arranged in parallel along the direction of the second partition plate and are arranged at intervals. The third heat dissipation area is close to the water outlet and consists of 13 columnar ribs. The 13 columnar ribs are divided into 4 groups. The 4 groups are arranged in parallel along the direction of the third partition plate and are arranged at intervals.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] This utility model uses a distributed columnar rib structure to improve heat dissipation performance. In addition to effectively reducing water resistance and increasing heat dissipation surface area, it also has the following heat dissipation advantages:

[0026] 1. Temperature field uniformity:

[0027] The design of the columnar ribs minimizes the difference in heat dissipation between the water-facing and water-repelling surfaces, which helps achieve a more uniform temperature distribution. This prevents local overheating or overcooling during the heat dissipation process, thereby improving overall heat dissipation efficiency.

[0028] 2. Enhanced convection heat transfer:

[0029] The columnar rib structure can increase the overall convection heat transfer area of ​​the heat dissipation rib, enhance the flow of fluid on the surface of the heat dissipation rib, and promote the rapid transfer and dissipation of heat. This enhancement of convection heat transfer is crucial to improving heat dissipation performance;

[0030] 3. Small pressure drop:

[0031] The arrangement of the columnar ribs helps to form a better flow channel and enhance the water flow effect, that is, using the flow of coolant to remove more heat; at the same time, it also helps to reduce pressure drop and improve heat dissipation efficiency;

[0032] 4. Structural stability and durability:

[0033] Columnar rib structures typically have good mechanical strength and rigidity, capable of withstanding certain pressure and impact. This stability helps maintain the overall performance and lifespan of the radiator during heat dissipation. Furthermore, a reasonable structural design can reduce stress concentration caused by vibration or thermal expansion and contraction, thereby improving the radiator's durability.

[0034] 5. Easy to process and manufacture:

[0035] Compared to some complex heat dissipation structures, the distributed columnar rib structure is relatively simple and easy to process and manufacture. This helps reduce production costs and cycles, and improves production efficiency. At the same time, the simple structure also facilitates subsequent maintenance and replacement work;

[0036] 6. Adaptability and flexibility:

[0037] The columnar rib structure can be flexibly designed and adjusted to meet different heat dissipation requirements and space constraints. For example, the heat dissipation performance can be optimized by changing parameters such as the diameter, height, and spacing of the columnar ribs. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The present invention will be further described below in conjunction with the embodiments:

[0043] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0044] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. At the same time, in the description of this utility model, the terms "first", "second", etc. are used only to distinguish the description and should not be understood as indicating or implying relative importance.

[0045] During product development, the design and layout of columnar ribs are crucial for improving product performance, optimizing heat dissipation, and ensuring structural strength. By combining advanced 3D data optimization technology with CAE (Computer-Aided Engineering) simulation analysis, macro-level adjustments to the columnar ribs are possible to maximize product performance.

[0046] For this reason, Figure 2-Figure 4 As shown, the utility model provides a water channel heat dissipation structure for a high-pressure controller housing. By introducing a precisely arranged columnar rib structure, it not only enhances the structural strength of the product, but also significantly optimizes its heat dissipation performance; at the same time, it ensures unobstructed flow of the water channel, achieving a harmonious unity of functionality and efficiency.

[0047] 1. Columnar reinforcement structure design:

[0048] Columnar ribs with a diameter of 3 mm are selected. This size takes into account the balance between reinforcement effect and process feasibility, ensuring sufficient support strength while avoiding unnecessary material waste, making the design more economical and efficient.

[0049] 2. Triangle layout optimization:

[0050] The innovative layout combines isosceles triangles, extending the layout horizontally across the heat dissipation space through an array. This layout cleverly increases the gaps between the columnar ribs by varying their side lengths, providing a smoother path for water flow. This also maximizes the heat dissipation surface area, promoting efficient heat dissipation.

[0051] Specifically, the present invention divides the cooling water flow structure integrated into the housing into two heat dissipation channels. The two heat dissipation channels are separated by a partition plate composed of three partitions. The partition plate is integrated into the housing.

[0052] Multiple columnar ribs are installed in each heat dissipation channel. The first heat dissipation channel has 53 columnar ribs, and the second heat dissipation channel has 59 columnar ribs. The outlet of the first heat dissipation channel is closer to the water outlet than the second heat dissipation channel, while the inlet of the second heat dissipation channel is closer to the water inlet than the first heat dissipation channel.

[0053] The first heat dissipation channel consists of a first heat dissipation area, a second heat dissipation area and a third heat dissipation area.

[0054] The first heat dissipation area, near the water inlet, consists of nine columnar ribs divided into three groups, arranged parallel to the first partition plate and spaced apart. The first group consists of four columnar ribs, the second group consists of three columnar ribs, and the third group consists of two columnar ribs.

[0055] The second heat dissipation area connects the first and third heat dissipation areas and consists of 38 columnar ribs. These 38 columnar ribs are divided into four groups, arranged parallel to the second partition plate and spaced apart. The first group consists of 11 columnar ribs, the second group consists of 5 columnar ribs, the third group consists of 11 columnar ribs, and the fourth group consists of 11 columnar ribs.

[0056] The third heat dissipation area, located near the water outlet, consists of six columnar ribs divided into two groups, each arranged parallel to the third partition plate and spaced apart. The first group consists of two columnar ribs, and the second group consists of four columnar ribs.

[0057] Except for the second group in the second heat dissipation area, in each transversely arranged columnar rib, two adjacent columnar ribs and their vertically adjacent columnar ribs form an isosceles triangle with a base length of 16 mm and two sides of 10 mm.

[0058] The second heat dissipation channel is also composed of a first heat dissipation area, a second heat dissipation area and a third heat dissipation area.

[0059] The first heat dissipation area, located near the water inlet, consists of seven columnar ribs divided into two groups, each arranged parallel to the first partition plate and spaced apart. The first group consists of five columnar ribs, and the second group consists of two columnar ribs.

[0060] The second heat dissipation area connects the first and third heat dissipation areas and is composed of 39 columnar ribs. These 39 columnar ribs are divided into four groups, arranged parallel to the second partition plate and spaced apart. The first group consists of 11 columnar ribs, the second group consists of 11 columnar ribs, the third group consists of 6 columnar ribs, and the fourth group consists of 11 columnar ribs.

[0061] The third heat dissipation area, located near the water outlet, consists of 13 columnar ribs divided into four groups, arranged parallel to and spaced apart from each other along the third partition. The first group consists of two columnar ribs, the second group of four, the third group of four, and the fourth group of three.

[0062] Except for the third group in the second heat dissipation area, in each transversely arranged columnar rib, two adjacent columnar ribs and their vertically adjacent columnar ribs form an isosceles triangle with a base length of 16 mm and two sides of 10 mm.

[0063] 3. Improved heat dissipation performance:

[0064] Surface area expansion: The three-dimensional arrangement of columnar ribs greatly increases the contact area between the shell wall and the external environment, forming more heat exchange interfaces, thereby significantly improving the overall heat dissipation capacity of the product.

[0065] 4. Airflow guidance: The triangular layout can also guide the surrounding water flow to form microcirculation, further accelerating the convection loss of heat and achieving a leap in heat dissipation efficiency.

[0066] 5. Unobstructed water flow design:

[0067] Streamlined design: The placement of the columnar ribs is carefully calculated to ensure they enhance strength without becoming an obstacle to water flow. Their smooth surface and optimal spacing effectively reduce flow resistance, ensuring efficient system operation.

[0068] 6. Maintenance and cleaning: This design also facilitates subsequent maintenance and cleaning work, reducing the problem of decreased heat dissipation performance caused by dirt accumulation.

[0069] The water channel heat dissipation structure of the high-voltage controller housing in this utility model adopts a multi-scale structural design. Based on the principles of heat conduction, columnar ribs of varying diameters are designed to form a gradient diameter structure. Columnar ribs with larger diameters are located closer to the heat source to provide greater heat capacity and initial heat dissipation area; while columnar ribs with smaller diameters are distributed farther from the heat source to reduce thermal resistance and promote heat transfer to more distant areas. A non-uniform layout strategy is employed, increasing the density and size of columnar ribs in heat-concentrated areas based on the heat distribution characteristics, while reducing the number of columnar ribs or using thinner diameters in areas with less heat, to achieve efficient heat conduction and dissipation.

[0070] Note that the above are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are possible for those skilled in the art without departing from the scope of protection of the present invention. Therefore, while the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the scope of the present invention. The scope of the present invention is determined by the scope of the appended claims.
