Description

Technical Field

[0001] This utility model relates to the field of heat dissipation device technology, and in particular to a high-performance heat dissipation device and an electronic speed controller. Background Technology

[0002] With the rapid development of electric aircraft (including drones, electric vertical takeoff and landing aircraft, etc.), the performance requirements of the core component of their power system—the electronic speed controller (ESC)—are increasing. The ESC generates a large amount of heat during operation. If this heat cannot be dissipated effectively and in a timely manner, the device temperature will rise, affecting its efficiency, stability, and lifespan, and in severe cases, even causing system failure.

[0003] Currently, the most common heat dissipation methods for electronic speed controllers used in the industry include the following: Passive cooling with metal heat sinks: Commonly used heat sinks made of aluminum or copper, dissipating heat through natural convection or limited surface area. While this type of structure is simple and reliable, its heat dissipation efficiency is limited in high power density applications, making it difficult to meet the heat dissipation requirements under continuous high current conditions.

[0004] Independent fan forced air cooling: This method enhances airflow and improves heat dissipation efficiency by adding a fan. However, this method increases the weight, size, and power consumption of the system, and the fans themselves also have reliability and noise issues, which is detrimental to the lightweight and integrated design of aircraft.

[0005] A Preliminary Exploration of Integrated Structural and Thermal Design: Some advanced designs attempt to combine heat dissipation functions with structural components, such as using the shell as a heat dissipation path. However, due to limitations in the synergy between material thermal conductivity and structural design, it is often difficult to achieve an ideal balance between "extreme lightweighting" and "efficient heat dissipation".

[0006] The main problems existing in the prior art include: Material performance contradictions: Traditional metal materials such as copper have excellent thermal conductivity, but their high density is not conducive to lightweighting; aluminum alloys are lightweight, but their thermal conductivity still has room for improvement, and the integration of structure and heat dissipation function is insufficient.

[0007] Inefficient heat dissipation path: The heat transfer path is not direct and the thermal resistance is large, resulting in low heat dissipation efficiency.

[0008] Poor environmental adaptability: The temperature inside the equipment compartment increases with operating time, affecting the heat dissipation temperature difference and further limiting the heat dissipation capacity.

[0009] Structure and function are disconnected: Heat sinks are usually existing as additional components and fail to be deeply integrated with the load-bearing structure of the aircraft, resulting in redundancy in weight and space.

[0010] Therefore, there is an urgent need for a heat dissipation solution that can achieve high efficiency, active operation, and integrated structure and function while ensuring extreme lightweight design, in order to meet the thermal management challenges of high-performance electronic speed controllers in electric aircraft under complex operating conditions.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example 1 One implementation method of this utility model is a high-performance heat dissipation device, such as... Figures 1 to 3 As shown, it includes: a heat dissipation shell 1 and a mounting shell 2; the heat dissipation shell 1 and the mounting shell 2 are fixedly connected.

[0027] The heat sink 1 includes a heat dissipation section 11, a temperature equalization section 12, and a cooling section 13 connected in sequence.

[0028] The heat dissipation section 11 is provided with a heat dissipation structure. In this embodiment, the heat dissipation structure adopts a heat dissipation substrate structure 111. The temperature equalization section 12 is provided with a temperature equalization plate 121; the cooling section 13 is provided with a plurality of cooling channels 131.

[0029] By setting up a heat dissipation section, a heat equalization section, and a cooling section, it constructs an efficient heat conduction path from the heat source to the external environment; the heat equalization plate uses the phase change heat transfer principle to quickly equalize the heat, and combined with the forced air cooling in the cooling channel, it significantly improves the heat dissipation efficiency and effectively controls the operating temperature of the electronic speed controller.

[0030] The heat sink 1 is made of aluminum alloy and is formed by one-piece molding, and its surface is coated with aluminum oxide.

[0031] The thermal conductivity of common aluminum alloys (such as 6061 and 6063) is typically between 150 and 220 W / (m·K). Therefore, the heat from the heat sink 1 can be transferred very quickly from the heat source (such as a motor, ESC, or battery) to the entire surface of the aluminum heat sink, and then dissipated into the air through the surface area, which is much more efficient than materials such as stainless steel.

[0032] In addition, using aluminum alloy materials can minimize the added weight while providing excellent heat dissipation capabilities, and a hard, wear-resistant, and insulating aluminum oxide coating can be formed through anodizing.

[0033] Alumina coatings not only significantly improve the surface thermal radiation coefficient and enhance heat dissipation, but also provide corrosion resistance, protecting the substrate from environmental corrosion such as moisture and salt spray.

[0034] Example 2 One implementation method of this utility model is a high-performance heat dissipation device, such as... Figures 1 to 3 As shown, the main technical solution of this embodiment is basically the same as that of Embodiment 1.

[0035] The heat sink 1 is provided with several mounting clips 14; the mounting shell 2 is provided with several mounting slots 21; the heat sink 1 and the mounting shell 2 are connected by the mounting clips 14 and the mounting slots 21.

[0036] Example 3 One implementation method of the electronic speed controller of this utility model is as follows: Figures 1 to 3 As shown, the main technical solution of this embodiment is basically the same as that of Embodiment 1 or Embodiment 2. Features not explained in this embodiment adopt the explanations in Embodiment 1 or Embodiment 2, and will not be repeated here. The difference between this embodiment and Embodiment 1 or Embodiment 2 is: An electronic speed controller includes a speed controller body 3 and the aforementioned high-performance heat dissipation device; the speed controller body 3 is fixedly disposed within a heat dissipation shell 1 and a mounting shell 2.

[0037] The mounting housing 2 is also provided with a wire inlet opening 23; the external connecting wire is connected to the speed controller body 3 through the wire inlet opening 23.

[0038] Furthermore, a clearance portion 122 is provided below the heat spreader 121. The clearance portion 122 is positioned to correspond to the protruding position of the speed controller body 3. By providing the clearance portion 122, the heat dissipation portion 11 and the cooling portion 13 can be closer to the speed controller body 3, so as to achieve a better heat dissipation effect.
