Description

Technical Field

[0001] This utility model relates to the field of VC heat sink technology, and in particular to a VC heat sink module. Background Technology

[0002] A VC cooling module is a heat dissipation device with a VC (Vapor Chamber) as its core component. It is usually composed of a heat dissipation plate, fin array, thermal pads, and other components. It utilizes the phase change heat transfer principle inside the heat dissipation plate to quickly conduct the heat generated by the heat source to the heat dissipation components such as the fin array. By increasing the heat dissipation area and promoting heat exchange, it efficiently dissipates heat to the surrounding environment to ensure that heat sources such as electronic devices operate stably within the normal temperature range.

[0003] However, in existing technologies, the heat spreader in some devices is susceptible to corrosion, especially in humid environments or environments with corrosive media such as acids, alkalis, and salts. The surface of the heat spreader may rust or corrode, affecting the stability of its internal structure and heat transfer performance, reducing the service life of the heat dissipation module. Furthermore, during the installation and use of the VC heat dissipation module, the heat spreader is prone to deformation and cracking, affecting its normal operation and potentially causing leakage of the internal working fluid, thus rendering the heat dissipation function ineffective. Utility Model Content

Stainless steel has good corrosion resistance, is not easy to rust or oxidize, and can be used for a long time in harsh environments. Copper is more susceptible to corrosion in certain environments. Some stainless steel has magnetic properties, which can bring advantages in certain electromagnetic application scenarios. Its magnetism can be used to achieve some special functions or to be used in conjunction with other magnetic components.

[0005] To achieve the above objectives, a VC heat dissipation module is provided, including a fixing plate A, a VC heat dissipation plate is disposed at the bottom of the fixing plate A, a fixing plate B is disposed on the right side of the VC heat dissipation plate, and a fixing plate C is disposed on the left side of the VC heat dissipation plate.

Stainless steel has high strength and hardness, making it less prone to deformation and damage compared to copper vapor chambers. It is more advantageous in environments that require withstanding large external forces or vibrations. Stainless steel has good corrosion resistance, is not easy to rust or oxidize, and can be used for a long time in harsh environments, while copper is more susceptible to corrosion in certain environments.

[0016] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0017] Reference Figure 1-4This utility model embodiment discloses a VC heat dissipation module, which includes a fixing plate A1. A VC heat dissipation plate 2 is provided at the bottom of the fixing plate A1. The VC heat dissipation plate is made of stainless steel. Stainless steel has high strength and hardness and can withstand greater external forces and pressures. During the use of the VC heat dissipation plate, it is not easy to deform or be damaged by external forces such as vibration and compression, thereby ensuring the integrity and stability of the heat dissipation plate structure and extending its service life. A fixing plate B3 is provided on the right side of the VC heat dissipation plate 2, and a fixing plate C4 is provided on the left side of the VC heat dissipation plate 2.

[0018] The rear side of the VC heat spreader 2 has two fin groups 5, which greatly increase the contact area between the heat dissipation module and the air or other heat dissipation medium. According to the basic principle of heat transfer, the larger the heat dissipation area, the faster the heat is transferred from the heat source to the surrounding environment, thereby improving heat dissipation efficiency and ensuring that the heat-generating equipment can maintain a suitable temperature range and maintain stable performance under high load. The rear side of the VC heat spreader 2 is fixedly connected to the main PAD 7, which has good flexibility and compressibility. It can fill the small gaps between the VC heat dissipation module and the heat source and other heat dissipation components, ensuring close contact between them, reducing the thermal resistance caused by air gaps, and allowing heat to be transferred to the heat dissipation module more smoothly. The rear side of the VC heat spreader 2 has two auxiliary PADs 6. When the heat distribution of the heat source is uneven, the auxiliary PADs can conduct heat from the higher temperature area to the lower temperature area according to the heat distribution, playing a role in balancing the heat distribution, making the temperature of the entire heat dissipation module more uniform, and improving heat dissipation efficiency.

[0019] Working Principle: The VC vapor chamber 2 is typically filled with a small amount of liquid working fluid (such as water). When one end of the VC vapor chamber 2 is heated, the liquid working fluid in contact with the heat source rapidly absorbs heat and vaporizes into steam. Since vaporization requires the absorption of a large amount of heat, it can quickly remove heat from the heat source, achieving efficient heat dissipation. The vaporized steam rapidly diffuses within the cavity of the VC vapor chamber 2. Because steam is less dense than liquid, it quickly moves towards the cooler end. When the steam reaches the cooler end of the VC vapor chamber 2, it condenses upon cooling, returning to a liquid state. During this process, the steam releases the heat absorbed during vaporization, transferring it to the outer shell of the VC vapor chamber 2 and then dissipating it into the surrounding environment. The condensed liquid needs to return to the heated end to continue the cycle. The inner wall of the VC vapor chamber 2 typically has capillary structures, such as capillary networks or grooves. These capillary structures generate capillary forces, causing the condensed liquid to flow back along the inner wall to the heated end under the action of capillary forces, where it is vaporized again, thus completing a full cycle.

[0020] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
