Description

Technical Field

[0001] This utility model relates to the field of heat dissipation structure technology, and more specifically, to a composite liquid cooling heat dissipation structure. Background Technology

[0002] With the continuous improvement of electronic device performance, their heat generation is also increasing. An effective heat dissipation structure is crucial for ensuring the stable operation of electronic devices and extending their service life. Liquid cooling, as an efficient heat dissipation method, is widely used in various high-performance electronic devices. Traditional liquid cooling structures typically employ a simple chamber design, with coolant flowing directly into the chamber from the inlet. This direct-flow fluid method has significant drawbacks. Due to fluid inertia, the liquid flow rate in the central region is significantly higher than that in the peripheral regions, leading to uneven heat dissipation. Therefore, we propose an improvement: a composite liquid cooling structure. Utility Model Content

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] Example 1, please refer to Figures 1-7 A composite liquid cooling structure includes a housing 101, which has a chamber. Both sides of the housing 101 have connection ports 102 communicating with the chamber, one for liquid inlet and one for liquid outlet. A flow equalization plate 2 is located near the liquid inlet within the chamber. The flow equalization plate 2 has several flow equalization holes 201, with the diameter of the flow equalization holes 201 near the liquid inlet being smaller than that of the flow equalization holes 201 far from the liquid inlet. This arrangement allows for reasonable distribution of the fluid flowing into the chamber, reducing the problem of large liquid volume in the middle zone and small liquid volume at the periphery caused by traditional direct-flow cooling. This results in a more uniform distribution of fluid within the chamber, improving heat dissipation. Furthermore, the smaller diameter of the holes near the liquid inlet reduces the flow rate in the middle zone, while the larger diameter of the holes far from the liquid inlet increases the flow rate in the periphery, making the coolant distribution within the chamber more uniform and thus improving overall heat dissipation efficiency.

[0020] Furthermore, a base 1 is connected to one side of the housing 101, and a heat equalization plate 2 is installed on the side of the base 1 close to the housing 101. The base 1 is used to fit against the component that needs heat dissipation in order to achieve heat transfer.

[0021] Furthermore, a number of heat-conducting pillars 103 are fixedly connected to the side of the base 1 near the outer shell 101, and the heat-conducting pillars 103 are all located in the cavity. The heat-conducting pillars 103 are directly connected to the base 1, which can further conduct the heat absorbed by the base 1 into the cavity. Moreover, the columnar structure of the heat-conducting pillars 103 increases the contact area with the coolant, so that the heat can be carried away by the coolant more quickly, thereby improving the heat dissipation speed.

[0022] Furthermore, the heat-conducting columns 103 are arranged in multiple rows, and the heat-conducting columns 103 in adjacent rows are staggered. The staggered arrangement can break the straight flow path of the coolant, making it easier for the coolant to diffuse to the surrounding area during the flow process, reducing the coolant stagnation in local areas, ensuring that the heat-conducting columns 103 in each area can fully contact the coolant, and reducing heat dissipation dead zones.

[0023] Furthermore, the chamber is provided with several fins 104, and the flow equalization plate 2 is located between the fins 104 and the liquid inlet. The several fins 104 are fixedly sleeved on the outer surface of several heat-conducting columns 103. The arrangement of the fins 104 expands the contact area with the coolant, so that the heat transferred by the heat-conducting columns 103 can be more fully absorbed by the coolant, and the heat exchange speed is accelerated.

[0024] Furthermore, a channel is provided between two adjacent fins 104 for the coolant to flow through. The channel provides a flow path for the coolant, allowing the coolant to continuously flow over the surfaces of the fins 104 and the heat-conducting pillars 103, continuously carrying away heat.

[0025] Furthermore, the center of the base 1 on the side away from the outer casing 101 is protruding, and the heat-conducting pillar 103 and the fins 104 are both located in the protruding area. This arrangement can specifically enhance the heat dissipation effect of the core heat-generating area.

[0026] Furthermore, two ramps 105 are provided on the inner wall of the cavity. The two ramps 105 are located on both sides of the connection port 102. The ramps 105 can make the coolant transition more smoothly when entering and exiting the connection port 102, reduce the turbulence and resistance caused by the right angle structure, and at the same time reduce the dead space in the cavity, so that the coolant can flow through the heat dissipation area more fully and improve the overall flow efficiency.

[0027] The outer shell 101, the flow equalization plate 2, and the heat conduction column 103 are all welded to the base 1, and the fins 104 are welded together with the heat conduction column 103.

[0028] Example 2 further optimizes the composite liquid cooling structure provided in Example 1. Specifically, the distance between several fins 104 is the same, and the equidistant fins 104 make the coolant flow more uniform.

[0029] Example 3 further optimizes the composite liquid cooling structure provided in Example 1. Specifically, the distance between several fins 104 decreases towards the base 1. The base 1 directly contacts the component to be cooled. When heat is transferred from the base 1 to the interior of the cavity, it decreases in a gradient. The heat is more concentrated in the area near the base 1. The decreasing spacing makes the density of fins 104 in this area greater and the heat dissipation area larger, which can absorb the concentrated heat more efficiently and improve the heat dissipation efficiency of the core area.

[0030] The process of using the composite liquid cooling heat dissipation structure provided by this utility model is as follows: The protruding area of ​​the base 1 away from the outer casing 101 is in contact with the component that needs to be cooled. The coolant enters through the inlet, then passes through the flow equalization plate 2 and the flow equalization hole 201 and enters the channel between the fins 104. Finally, it is discharged through the outlet. During this process, the coolant absorbs the heat transferred by the base 1 through the fins 104 and the heat conduction column 103.
