[0002] Heat sinks are specialized devices used to cool and dissipate heat from equipment. There are various types of heat sinks, and different equipment uses different types. In the electronics industry, due to space constraints, stacked finned heat sinks are generally used to dissipate heat from electronic components. Their main working principle is to conduct heat away from the electronic components through finned heat sinks, thus dissipating heat outwards. Traditionally, heat sink fins are typically welded together, with multiple fins stacked and welded together to form heat dissipation channels between adjacent fins. However, this method is inefficient, involves complex welding processes, and requires high quality. Therefore, external cooling fans are often used to dissipate heat from the heat sinks.

The upper and lower heat sink fins are interference-fitted by the upper limit tube and the bottom hole to form a stable stack. A heat dissipation channel is formed between the upper and lower heat sink fins to facilitate heat dissipation. Liquid cooling pipes are also added inside the upper limit tube and the lower limit tube. The liquid cooling pipes can be connected to an external water cooling system to improve the heat dissipation efficiency of the heat sink.

[0006] According to the stacked finned heat sink, the heat sink fins, lower limiting tube, limiting ring and upper limiting tube are integrally formed by stamping.

[0007] According to the stacked finned heat sink, the number of bottom holes, lower limiting tubes, limiting rings and upper limiting tubes are all provided and are evenly distributed on the heat sink fins.

[0022] Reference Figure 1-4This utility model discloses a stacked finned heat sink, comprising: a heat dissipation assembly 1 and a liquid cooling pipe 2. The heat dissipation assembly 1 includes heat dissipation fins 101, a bottom hole 102, a lower limiting pipe 103, a limiting ring 104, and an upper limiting pipe 105. The bottom hole 102 is provided at the bottom of the heat dissipation fins 101, and the lower limiting pipe 103 is fixedly connected to the top of the heat dissipation fins 101. The limiting ring 104 is fixedly connected to the circumferential surface of the lower limiting pipe 103. The top of 104 is fixedly connected to an upper limit tube 105. The bottom hole 102, lower limit tube 103, limit ring 104, and upper limit tube 105 are vertically connected. The liquid cooling tube 2 is located inside the lower limit tube 103. The liquid cooling tube 2 is a metal capillary copper tube. Several of each of the bottom hole 102, lower limit tube 103, limit ring 104, and upper limit tube 105 are provided and evenly distributed on the heat dissipation fins 101. The number of heat dissipation components 1 is [number missing]. Several heat dissipation components are stacked vertically. The upper limit tube 105 is interference-fitted with the bottom hole 102 of the adjacent upper heat dissipation component 1. During assembly, the upper and lower heat dissipation components 1 are stacked vertically, and the bottom hole 102 of the upper heat dissipation component 1 is aligned with the upper limit tube 105 of the lower heat dissipation component 1. After heating the heat dissipation fins 101 of the upper heat dissipation component 1, the upper limit tube 105 is inserted into the bottom hole 102.

[0023] The lower limit tube 103 is perpendicular to the heat dissipation fins 101. The heat dissipation fins 101, the lower limit tube 103, the limit ring 104 and the upper limit tube 105 are integrally formed by stamping, which reduces welding operations and simplifies the production process.

[0024] Working principle: During assembly, the upper and lower heat dissipation components 1 are stacked vertically, and the bottom hole 102 of the upper heat dissipation component 1 is aligned with the upper limit tube 105 of the lower heat dissipation component 1. After heating the heat dissipation fins 101 of the upper heat dissipation component 1, the upper limit tube 105 is inserted into the bottom hole 102. The limiting ring 104 restricts the downward movement of the upper heat dissipation fins 101, so that multiple upper limit tubes 105 on the heat dissipation fins 101 are inserted into the upper heat dissipation fins 101 at equal lengths. Then, the liquid cooling pipe 2 is inserted into the upper limit tube 105 and the lower limit tube 103 and glued and fixed. Both ends of the liquid cooling pipe 2 pass through all the heat dissipation fins 101 and are connected to the external water cooling system, so that the radiator can be combined with the water cooling system to dissipate heat simultaneously and improve heat dissipation efficiency.
