DETAILED DESCRIPTION

[0036] The preferred embodiments of the utility model will be described in detail below with reference to the drawings, wherein the drawings form a part of the utility model, and are used together with the embodiments of the utility model to explain the principles of the utility model, and are not used to limit the scope of the utility model.

[0037] Embodiment 1

[0038] One specific embodiment of the utility model discloses a liquid cooling holding ring with a bending flow channel, as shown in Figure 2 , Figure 3 , comprising: a holding ring body 1, the inside of the holding ring body 1 is provided with a bending inner flow channel 101; the holding ring body 1 is a split structure, comprising: an upper ring 11, a middle ring 12 and a lower ring 13; the lower surface of the upper ring 11 is provided with a first L-shaped flow channel 104, a first linear flow channel 106 and a second L-shaped flow channel 108; the middle ring 12 is provided with a first U-shaped flow channel 105 and a second U-shaped flow channel 107 penetrating through the upper and lower surfaces thereof; the upper surface of the lower ring 13 is provided with a second linear flow channel 109 and a third linear flow channel 110; after the upper ring 11, the middle ring 12 and the lower ring 13 are welded into an entirety, the first L-shaped flow channel 104, the first U-shaped flow channel 105, the first linear flow channel 106, the second U-shaped flow channel 107 and the second L-shaped flow channel 108 are sequentially communicated, and the second linear flow channel 109 and the third linear flow channel 110 can respectively close the bottom end slot of the first U-shaped flow channel 105 and the second U-shaped flow channel 107, to form the inner flow channel 101.

[0039] Preferably, as shown in Figure 2 , Figure 3 , Figure 4 , the inner flow channel 101 is symmetrically provided with two in the inside of the holding ring body 1. As shown in Figure 2 , two inner flow channels 101 are arranged in the liquid cooling holding ring, and pass through the holding ring body 1 from front to back, so that the available solid structure in the holding ring body 1 is fully utilized, and the heat exchange cooling efficiency is enhanced.

[0040] The working principle of the liquid-cooled retaining ring of this utility model is as follows: After the electronic components start working, they generate heat, which heats the retaining ring body 1. The liquid cooling system drives the low-temperature liquid working medium to flow into the inner flow channel 101. The liquid cooling working medium and the retaining ring body 1 exchange heat, which carries away the heat, thereby achieving the effect of temperature control for the electronic components.

[0041] Furthermore, such as Figure 2 As shown, the retaining ring body 1 is also provided with a coolant inlet 102 and a coolant outlet 103 that are connected to the inner flow channel 101. Both the coolant inlet 102 and the coolant outlet 103 are connected to the outer surface of the retaining ring body 1.

[0042] Furthermore, such as Figure 1 As shown, the coolant inlet 102 is used to connect to the inlet connector 2, and the inlet connector 2 is used to introduce coolant into the inner flow channel 101 of the retaining ring body 1.

[0043] Furthermore, such as Figure 1 As shown, the coolant outlet 103 is used to connect to the outlet connector 3, and the outlet connector 3 is used to discharge coolant from the inner flow channel 101 of the retaining ring body 1.

[0044] To ensure good heat exchange between the coolant and the liquid-cooled ring, the liquid working fluid must have sufficient heat exchange area within the ring body 1. In this invention, the design of the inner flow channel 101 within the liquid-cooled ring is as follows:

[0045] Specifically, one end of the first L-shaped flow channel 104 is connected to the coolant inlet 102, and the other end is connected to one end of the first U-shaped flow channel 105.

[0046] Specifically, such as Figure 5 As shown, the bottom of the first U-shaped flow channel 105 and the second U-shaped flow channel 107 are connected to the lower surface of the middle ring 12, and both ends of the first U-shaped flow channel 105 and the second U-shaped flow channel 107 are connected to the upper surface of the middle ring 12.

[0047] like Figure 5 , Figure 6 As shown, the starting ends of the first U-shaped flow channel 105 and the second U-shaped flow channel 107 are located on the upper surface of the middle ring 12, pass through the middle ring 12 and connect to the lower surface of the middle ring 12. The first U-shaped flow channel 105 and the second U-shaped flow channel 107 are connected to the side of the starting end by a slot at the bottom of the middle ring 12, and pass through the middle ring 12 again to connect to its upper surface as the end openings of the first U-shaped flow channel 105 and the second U-shaped flow channel 107.

[0048] Specifically, one end of the first U-shaped flow channel 105 is connected to the first L-shaped flow channel 104, and the other end is connected to one end of the first linear flow channel 106.

[0049] Specifically, one end of the second U-shaped flow channel 107 is connected with the other end of the first linear flow channel 106, and the other end is connected with one end of the second L-shaped flow channel 108.

[0050] Specifically, the other end of the second L-shaped flow channel 108 is connected with the cooling liquid outlet 103.

[0051] Further, as shown in Figure 3 、 Figure 7 The second linear flow channel 109 and the third linear flow channel 110 on the upper surface of the lower ring 13 are respectively aligned with the bottom cavities of the first U-shaped flow channel 105 and the second U-shaped flow channel 107 on the middle ring 12, and can close the bottom cavities of the first U-shaped flow channel 105 and the second U-shaped flow channel 107.

[0052] Further, positioning pin holes 14 are arranged on the upper ring 11, the middle ring 12 and the lower ring 13; pins are installed in the positioning pin holes 14, and are used for positioning the relative positions of the upper ring 11, the middle ring 12 and the lower ring 13.

[0053] In the utility model, since the liquid cooling clamping ring is directly contacted with electronic components, the liquid cooling clamping ring is required to have good sealing property, and at the same time, in order to ensure that the flow resistance of the complex flow channel is less than the pressure head of the driving pump, the liquid cooling clamping ring cannot be formed by the 3D mode. Because the internal flow channel is complex, the conventional soldering splicing forming cannot be produced, and finally the clamping ring main body 1 is designed as a three-section structure fixed by welding, so that the liquid cooling clamping ring is formed.

[0054] The specific processing procedure is as follows:

[0055] First step, the upper ring 11, the middle ring 12 and the lower ring 13 are first machined according to the requirements, in order to ensure the reliability of welding, the welding width is not less than 3mm at any welding position, and a machining allowance is reserved at the position prone to deformation for post-welding machining;

[0056] Second step, the solder is machined according to the size of the welding surface, and the positioning pin is installed in the directional pin hole 14 of the upper ring 11, the middle ring 12 and the lower ring 13 for positioning assembly;

[0057] Third step, the upper ring 11, the middle ring 12 and the lower ring 13 are pressed tightly, and then vacuum brazing is carried out;

[0058] Fourth step, after welding, pressure testing is carried out, and the pressure is required to be greater than the pressure head of the pump to ensure that no leakage occurs;

[0059] Fifth step, after the pressure test is passed, final machining is carried out, and then leakage is checked again to ensure the reliability.

[0060] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application.
