Detailed Implementation

[0027] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0028] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0029] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0031] To improve or solve the problem of poor heat dissipation of heat-generating parts of information and communication technology equipment due to localized overheating of the refrigerant in related technologies, this application provides a refrigerant diversion device 1, see reference. Figures 1-4 As shown, it includes: a cavity 10, a flow channel 11, and a flow guide 13; the cavity is provided with an opening 12; the flow channel 11 is located inside the cavity 10; the flow channel 11 is provided with a refrigerant inlet 112 and a refrigerant outlet 111; Optionally, there may be multiple flow channels 11, which are located within the cavity.

[0032] The flow guide 13 is used to guide the refrigerant from the opening 12 into the refrigerant inlet 112 of at least one of the plurality of flow guide channels 11, so that the refrigerant from the opening flows out from the refrigerant outlet 111 corresponding to the refrigerant inlet 112 of the at least one flow guide channel 11; the refrigerant in the at least one flow guide channel 11 is used to dissipate heat from the heat-generating parts of the device.

[0033] Multiple flow channels are incorporated into the cavity, providing the refrigerant from the opening with more flow path options. Compared to a single flow channel, multiple channels disperse the refrigerant flow, preventing a large amount of refrigerant from concentrating in one channel. For example, when the equipment generates a large amount of heat and the amount of refrigerant entering the cavity increases, multiple flow channels can work together to transport the refrigerant, preventing flow obstruction caused by excessive refrigerant flow in one channel, which could lead to localized overheating.

[0034] Each flow channel has an independent refrigerant inlet and outlet, with the refrigerant inlets all facing the cavity opening. This layout allows for a more even distribution of refrigerant throughout the flow channels. After entering the cavity, the refrigerant does not concentrate in a few areas due to limited path options, thus ensuring a more balanced distribution of refrigerant throughout the cavity and reducing overheating caused by localized refrigerant buildup.

[0035] The flow guide directs refrigerant from the opening into the refrigerant inlet of at least one of the multiple flow channels. This design allows for more flexible refrigerant distribution, enabling targeted refrigerant delivery to specific flow channels based on the actual needs of different heat-generating components within the equipment. For example, when a particular area of ​​the equipment experiences severe overheating, the flow guide can direct more refrigerant into the flow channel closer to that area, allowing the refrigerant to directly act on the heat-generating component and improve heat dissipation efficiency.

[0036] Therefore, in this embodiment, the refrigerant from the cavity opening is guided into the refrigerant inlet by the flow guide, so that the refrigerant flows out from the refrigerant outlet corresponding to the refrigerant inlet to dissipate heat from the heat-generating parts of the equipment. Thus, the refrigerant flow guide device of this application introduces more refrigerant into the heat-generating parts of the equipment, thereby avoiding overheating of the heat-generating parts of the equipment and improving the heat dissipation effect of the heat-generating parts of the equipment.

[0037] Furthermore, the plurality of flow channels are arranged side by side adjacent to each other in sequence; each flow channel is provided with a refrigerant inlet and a refrigerant outlet along the flow direction of the refrigerant; the refrigerant inlet of each flow channel is arranged facing the opening 12 of the cavity 10; the flow guide 13 is located between the opening 12 and the refrigerant inlet 112.

[0038] The cavity 10 provides a relatively independent space for the flow and guidance of the refrigerant, while the opening 12 serves as the inlet for the refrigerant to enter the cavity 10, ensuring that the refrigerant can smoothly enter the device and prepare for subsequent flow guidance and heat dissipation.

[0039] A flow guide channel is installed inside the cavity, with a refrigerant inlet and outlet along the refrigerant flow direction. The flow guide channel clearly defines the refrigerant flow path within the cavity, ensuring that the refrigerant flows in a predetermined direction and preventing disordered diffusion within the cavity. This guarantees that the refrigerant can effectively flow to the heat-generating parts of the equipment that require heat dissipation.

[0040] The flow guide 13 is positioned between the opening 12 and the refrigerant inlet 112 within the cavity. Its function is to accurately guide the refrigerant from the opening into the refrigerant inlet 112. Guided by the flow guide 13, the refrigerant can enter the flow channel more smoothly, avoiding localized overheating caused by poor flow before entering the channel. If the refrigerant cannot enter the flow channel smoothly, it may accumulate near the opening, causing excessive refrigerant volume and slow flow in certain areas, leading to localized overheating. The presence of the flow guide ensures that the refrigerant enters the flow channel evenly and orderly, flowing out from the refrigerant outlet corresponding to the refrigerant inlet, guaranteeing the uniformity of the refrigerant throughout the flow process and improving the heat dissipation effect on the heat-generating parts of the equipment.

[0041] See Figure 1As shown, each flow channel is provided with a refrigerant inlet and a refrigerant outlet along the flow direction of the refrigerant; the refrigerant inlet of each flow channel is oriented towards the opening of the cavity; the flow guide is used to guide the refrigerant from the opening into the refrigerant inlet of at least one of the multiple flow channels, so that the refrigerant from the opening flows out from the refrigerant outlet of at least one flow channel; the refrigerant in at least one flow channel is used to dissipate heat from the heat-generating parts of the equipment.

[0042] For example, multiple flow channels 11 are arranged side by side adjacent to each other along the X direction; the refrigerant inlet of each flow channel 11 is arranged facing the opening 12 in front, and optionally, the refrigerant inlets of each flow channel 11 are flush. The flow guide 13 can be connected to the refrigerant inlet of one or two of the multiple flow channels 11, so that the refrigerant can enter the refrigerant inlet of the flow channel along the flow guide 13, thereby dissipating heat from the heat-generating part corresponding to the flow channel.

[0043] Multiple airflow channels are arranged side-by-side, each with a refrigerant inlet and outlet. The airflow guides the refrigerant from the cavity openings evenly into each channel. This design ensures a relatively balanced distribution of refrigerant to each channel, preventing excessive refrigerant flow in some channels due to uneven distribution, which could lead to refrigerant waste and localized low temperatures. It also prevents overheating caused by insufficient refrigerant flow in other channels. For example, in the cooling system of a large server, multiple parallel airflow channels ensure that the cooling needs of different areas of the server are met, guaranteeing stable server operation.

[0044] By adjusting the flow guides, the refrigerant flow rate in each flow channel can be precisely controlled. Based on the heat dissipation requirements of different areas of the equipment's heat-generating components, an appropriate amount of refrigerant is allocated to each flow channel. For areas with higher heat generation, the refrigerant flow rate in the corresponding flow channel can be increased; for areas with lower heat generation, the refrigerant flow rate can be decreased. This precise control further improves refrigerant utilization efficiency and avoids energy waste.

[0045] It is understandable that the flow channel can be either a straight channel or an arc-shaped channel; there is no limitation here.

[0046] Optionally, the flow guiding channel is a reversing channel; the flow guiding channel includes: a first straight channel, a second straight channel, and an arc-shaped channel; one end of the first straight channel is provided with a refrigerant inlet; the second straight channel is stacked with the first straight channel, and one end of the second straight channel is provided with a refrigerant outlet; the two ends of the arc-shaped channel are respectively connected to the other ends of the first straight channel and the other ends of the second straight channel.

[0047] Optionally, both the refrigerant inlet and the refrigerant outlet face the opening 12 of the cavity.

[0048] See Figure 1 and Figure 2 As shown, the flow guiding channel includes a first straight channel 17, a second straight channel 18, and an arc-shaped channel 16; the second straight channel 18 is located above the first straight channel 17, and the first straight channel 17, the arc-shaped channel 16, and the second straight channel 18 are sequentially connected to form a flow guiding channel 11, in which the refrigerant flows along the flow path 14. Optionally, the refrigerant outlet, the refrigerant inlet, and the cavity opening 12 are located on the same side of the cavity.

[0049] After entering through the refrigerant inlet in the first straight channel, the refrigerant must traverse the entire first straight channel, then turn through an arc-shaped channel into the second straight channel, and finally exit from the refrigerant outlet in the second straight channel. This reversible flow path significantly extends the refrigerant's journey within the guide channel. Compared to a straight channel, the extended journey allows the refrigerant more time to exchange heat with the inner wall of the guide channel and the heat-generating parts of the equipment, enabling it to fully absorb the heat generated by the equipment and thus improve heat dissipation efficiency.

[0050] The stacked arrangement of the first and second straight channels, combined with the connection of the arc-shaped channels, creates an orderly path for refrigerant flow. This orderly flow avoids chaotic eddies and backflow of the refrigerant inside the equipment, reduces the temperature rise caused by excessive refrigerant residence time in local areas, and allows the refrigerant to absorb heat from all parts of the equipment more evenly, improving the uniformity of heat dissipation.

[0051] Furthermore, the second linear channel 18 has multiple refrigerant outlet holes 15 arranged in a linear pattern at equal intervals on the side near the heat-generating part of the equipment; the refrigerant in the refrigerant outlet holes is used to dissipate heat from the heat-generating part of the equipment.

[0052] See Figure 2 As shown, multiple refrigerant outlet holes 15 are evenly distributed on the upper side of the second linear channel 18 along the same straight line. The top of the refrigerant outlet holes 15 faces each heat-generating part of the equipment, thereby achieving the purpose of heat dissipation for the heat-generating parts of the equipment.

[0053] The second linear channel can be designed close to the heat-generating parts of the device. Combined with multiple refrigerant outlets evenly spaced in a linear pattern, it enables precise heat dissipation of the heat-generating components. After the refrigerant is ejected from the outlets, it acts directly on the heat-generating elements, quickly carrying away heat. For example, for high-power CPUs or GPUs, this targeted heat dissipation design effectively prevents overheating due to heat buildup, ensuring stable operation of the device.

[0054] The refrigerant ejected from the evenly spaced refrigerant outlets creates a convection effect. During injection, the refrigerant draws in surrounding air, creating forced convection and further accelerating heat transfer. This convection effect allows the refrigerant to more quickly remove heat generated by the equipment, improving heat dissipation efficiency.

[0055] Multiple refrigerant outlets simultaneously eject refrigerant, effectively increasing the contact area between the refrigerant and the heat-generating parts of the equipment. During the ejection process, the refrigerant forms tiny droplets or airflows, which can fully contact the equipment surface and quickly absorb heat. Compared to heat dissipation methods with a single outlet or a small number of outlets, multiple refrigerant outlets distributed linearly and at equal intervals can significantly increase the heat dissipation area and improve heat transfer efficiency.

[0056] It is understandable that the flow guide can have a variety of different structures. The flow guide can be a circular or polygonal component with channels, or it can be a rectangular groove with an opening on one side. There are no restrictions here.

[0057] Optionally, the flow guide includes a baffle 110; the baffle 110 is disposed within the cavity 10; the baffle is rotatable relative to the cavity in a direction to one side of the baffle or in a direction to the other side of the baffle; one end of the baffle is close to the opening, and the other end of the baffle is close to the refrigerant inlet of at least one flow guide channel; a first refrigerant space for refrigerant passage is formed between the inner wall of the cavity and one side of the baffle in the space between the opening and the refrigerant inlet; a second refrigerant space for refrigerant passage is formed between the inner wall of the cavity and the other side of the baffle in the space between the opening and the refrigerant inlet; one side of the baffle is the opposite side of the other side of the baffle; one end of the baffle is the opposite end of the other end of the baffle; the first refrigerant space or the second refrigerant space communicates with the refrigerant inlet of at least one flow guide channel to guide refrigerant from the opening into the refrigerant inlet of at least one flow guide channel via the baffle.

[0058] In some embodiments, see Figure 2 and Figure 3 As shown, the flow guide includes a baffle 110; the body of the baffle is provided with a rotating hole 19, and a rotating shaft 119 is provided in the rotating hole 19. The upper and lower ends of the rotating shaft 119 are rotatably connected to the cavity. When the baffle 110 rotates around the rotating shaft, the baffle 110 can rotate inward or outward.

[0059] See Figure 3As shown, the flow channels include flow channel a 113, flow channel b 114, and flow channel c 115; the refrigerant inlets 112 of flow channels a 113, b 114, and c 115 are all oriented towards the opening 12; the baffle includes baffle a 118; baffle a 118 is rotatably connected to the cavity via a pivot 119. A first refrigerant space 116 for refrigerant passage is formed between the inner wall of the cavity and the left side of the baffle; a second refrigerant space 117 for refrigerant passage is formed between the inner wall of the cavity and the right side of the baffle. When the upper end of baffle a 118 rotates to the refrigerant inlet of the leftmost guide channel a 113, baffle a 118 blocks the refrigerant inlets of guide channels b 114 and c 115, thereby increasing the refrigerant flow rate into the first refrigerant space 116 per unit time, and further increasing the refrigerant flow rate into guide channel a 113 per unit time. This provides targeted cooling to the heat-generating components of the equipment corresponding to guide channel a 113. Similarly, when the upper end of baffle b 118 rotates to the refrigerant inlet of the rightmost guide channel c 115, it also provides targeted cooling to the corresponding heat-generating components. When the upper end of baffle b 118 rotates to the refrigerant inlet of the middle guide channel a 114, refrigerant can simultaneously enter guide channels a 113, b 114, and c 115. Due to the presence of baffle b 118, the refrigerant flow rate into guide channel b 114 is blocked. The passage of refrigerant in channel 114 has a certain obstructing effect, thereby reducing the refrigerant flow rate entering channel b 114 per unit time, while increasing the refrigerant flow rate entering channel a 113 and channel c 115.

[0060] The baffle design connects the first or second refrigerant space to the refrigerant inlet of at least one flow channel, enabling precise diversion of refrigerant from the opening into the corresponding flow channel. This directional guidance method allows for flexible adjustment of the refrigerant flow direction based on the needs of different heat-generating components within the equipment. For example, if a certain area of ​​the equipment experiences severe overheating, the position or shape of the baffle can be adjusted to allow more refrigerant to enter through the flow channel corresponding to that area, thereby focusing heat dissipation on that heat-generating component and improving the targeting and effectiveness of heat dissipation.

[0061] Furthermore, the refrigerant diversion device also includes a power unit; the power unit is connected to the baffle; the power unit is used to drive the other end of the baffle to rotate toward the refrigerant inlet of at least one diversion channel so that the first refrigerant space or the second refrigerant space is connected to the refrigerant inlet of at least one diversion channel.

[0062] Understandably, there are many options for the power unit, including various types of motors or other similar devices; no specific choice is made here.

[0063] Optionally, the power unit includes a stepper motor; the output shaft of the stepper motor is connected to a rotating shaft within the rotating hole 19.

[0064] Equipment such as ICT devices experiences dynamic changes in heat generation across different operating states. A power unit rotates the other end of a baffle towards the refrigerant inlet of at least one flow channel. This allows for flexible adjustment of the connection between the first or second refrigerant space and the refrigerant inlet of the flow channel based on the real-time heat generation of the equipment. For example, when a specific module of the equipment experiences a surge in heat due to high load operation, the power unit can quickly drive the baffle to rotate, increasing the refrigerant space connected to the corresponding flow channel. This allows more refrigerant to flow into that channel, focusing on cooling the heat-generating component and precisely matching the heat dissipation needs of different parts of the equipment. By rotating the baffle with the power unit, the refrigerant flow rate in each flow channel can be balanced in real time, preventing localized refrigerant accumulation that could lead to overheating. Simultaneously, it ensures that each heat-generating component receives sufficient refrigerant for heat dissipation, improving overall heat dissipation efficiency.

[0065] Furthermore, the multiple flow channels include multiple first flow channels; the multiple first flow channels are arranged side by side adjacent to each other in sequence, and the refrigerant inlets of the multiple first flow channels all face the opening of the cavity; a baffle corresponds to the refrigerant inlet of the multiple first flow channels, so that when the power device drives a baffle to rotate to the refrigerant inlet of the corresponding first flow channel, the baffle will guide the refrigerant from the opening into the refrigerant inlet of the corresponding first flow channel.

[0066] In some embodiments, the baffle includes a first baffle and a second baffle; the power unit includes a first power unit and a second power unit; the first power unit is connected to the first baffle; the second power unit is connected to the second baffle; in the space between the opening and the refrigerant inlet, a third refrigerant space for refrigerant passage is formed between the inner wall of the cavity and one side of the first baffle; in the space between the opening and the refrigerant inlet, a fourth refrigerant space for refrigerant passage is formed between the inner wall of the cavity and one side of the second baffle; in the space between the opening and the refrigerant inlet, a fifth refrigerant space for refrigerant passage is formed between the first baffle and the second baffle; the first power unit drives the first baffle to rotate, and the second power unit drives the second baffle to rotate, so that the third refrigerant space, the fourth refrigerant space, or the fifth refrigerant space is connected to the refrigerant inlet of at least one flow channel.

[0067] See Figure 5As shown, the multiple flow channels include a first flow channel a 120, a first flow channel b 121, a first flow channel c 122, a first flow channel d 123, a first flow channel e 124, and a first flow channel f 125; the refrigerant inlets of the first flow channels a 120, b 121, c 122, d 123, e 124, and f 125 are all oriented towards the opening 12.

[0068] The baffle includes a first baffle 129 and a second baffle 130; in the space between the opening and the refrigerant inlet, a third refrigerant space 126 is formed between the inner wall of the cavity and the left side of the first baffle 129 for refrigerant passage; in the space between the opening and the refrigerant inlet, a fourth refrigerant space 128 is formed between the inner wall of the cavity and the right side of the second baffle 130 for refrigerant passage; and in the space between the opening and the refrigerant inlet, a fifth refrigerant space 127 is formed between the first baffle 129 and the second baffle 130 for refrigerant passage.

[0069] The first baffle 129 corresponds to the first flow channel a 120, the first flow channel b 121 and the first flow channel c 122; the second baffle 130 corresponds to the first flow channel d 123, the first flow channel e 124 and the first flow channel f 125; When the upper end of the first baffle 129 rotates to the refrigerant inlet of the leftmost first guide channel a 120, the first baffle 129 blocks the first guide channels b 121 and c 122, thereby increasing the refrigerant flow rate entering the third refrigerant space 126 per unit time, and further increasing the refrigerant flow rate entering the first guide channel a 120 per unit time. This provides targeted cooling to the heat-generating parts of the equipment corresponding to the first guide channel a 120. Similarly, when the upper end of the first baffle 129 rotates to the refrigerant inlet of the first guide channel c 122, it also provides targeted cooling to the corresponding heat-generating parts of the equipment. When the upper end of the first baffle 129 rotates to the refrigerant inlet of the middle first guide channel b 121, refrigerant can simultaneously enter the first guide channels a 120, b 121, and c 122. Due to the presence of the first baffle 129, the refrigerant flow rate entering the first guide channel b 120 is blocked. The passage of refrigerant in 121 has a certain obstructing effect, thereby reducing the refrigerant flow rate entering the first guide channel b 121 per unit time, while increasing the refrigerant flow rate entering the first guide channel a 120 and the first guide channel c 122.

[0070] Similarly, the second baffle 130, corresponding to the first guide channel d 123, the first guide channel e 124 and the first guide channel f 125, can also achieve the above effect, which will not be elaborated here.

[0071] In addition, when the upper end of the first baffle 129 rotates to the refrigerant inlet of the first guide channel c 122 and when the upper end of the second baffle 130 rotates to the refrigerant inlet of the first guide channel d 123, the refrigerant flow rate entering the first guide channel a 120 and the first guide channel b 121 per unit time decreases, the refrigerant flow rate entering the first guide channel c 122 and the first guide channel d 123 per unit time increases, and the refrigerant flow rate entering the first guide channel e 124 and the first guide channel f 125 per unit time decreases.

[0072] In other embodiments, the baffle includes a third baffle, a fourth baffle, and a fifth baffle; the power unit includes a third power unit, a fourth power unit, and a fifth power unit; the third power unit is connected to the third baffle; the fourth power unit is connected to the fourth baffle; and the fifth power unit is connected to the fifth baffle. Within the space between the opening and the refrigerant inlet, a sixth refrigerant space is formed between the inner wall of the cavity and one side of the third baffle for refrigerant passage; within the space between the opening and the refrigerant inlet, a seventh refrigerant space is formed between the third baffle and the fourth baffle for refrigerant passage; within the space between the opening and the refrigerant inlet, an eighth refrigerant space is formed between the fourth baffle and the fifth baffle for refrigerant passage. The inner wall of the cavity and one side of the fifth baffle form a ninth refrigerant space for the refrigerant to pass through; The third power unit drives the third baffle to rotate, the fourth power unit drives the fourth baffle to rotate, and the fifth power unit drives the fifth baffle to rotate so that the sixth refrigerant space, the seventh refrigerant space, the eighth refrigerant space or the ninth refrigerant space are connected to the refrigerant inlet of at least one flow channel.

[0073] See Figure 6 As shown, the multiple flow channels include the first flow channel g 131, the first flow channel h 132, the first flow channel j 133, the first flow channel k 134, the first flow channel l 135, the first flow channel m 136, the first flow channel n 137, the first flow channel o 138, and the first flow channel p 139; The refrigerant inlets of the first flow guiding channels g 131, h 132, j 133, k 134, l 135, m 136, n 137, o 138, and p 139 are all oriented towards the opening 12.

[0074] The baffles include a third baffle 144, a fourth baffle 145, and a fifth baffle 146; a sixth refrigerant space 140 for refrigerant passage is formed between the inner wall of the cavity and the left side of the third baffle 144 in the space between the opening and the refrigerant inlet; a seventh refrigerant space 141 for refrigerant passage is formed between the third baffle 144 and the fourth baffle 145 in the space between the opening and the refrigerant inlet; an eighth refrigerant space 142 for refrigerant passage is formed between the fourth baffle 145 and the fifth baffle 146 in the space between the opening and the refrigerant inlet; and a ninth refrigerant space 143 for refrigerant passage is formed between the inner wall of the cavity and the right side of the fifth baffle 146.

[0075] The third baffle 144 corresponds to the first flow channel g 131, the first flow channel h 132 and the first flow channel j 133; the fourth baffle 145 corresponds to the first flow channel k 134, the first flow channel l 135 and the first flow channel m 136; the fifth baffle 146 corresponds to the first flow channel n 137, the first flow channel o 138 and the first flow channel p 139.

[0076] When the upper end of the third baffle 144 rotates to the refrigerant inlet of the leftmost first guide channel g 131, the third baffle 144 blocks the first guide channels h 132 and j 133, thereby increasing the refrigerant flow rate entering the sixth refrigerant space 140 per unit time, and further increasing the refrigerant flow rate entering the first guide channel g 131 per unit time. This provides targeted heat dissipation and cooling for the heat-generating components of the equipment corresponding to the first guide channel g 131. Similarly, when the upper end of the third baffle 144 rotates to the refrigerant inlet of the first guide channel j 133, it also provides targeted heat dissipation and cooling for the corresponding heat-generating components. When the upper end of the third baffle 144 rotates to the refrigerant inlet of the first guide channel h 132, refrigerant can simultaneously enter the first guide channels g 131, h 132, and j 133. Due to the presence of the third baffle 144, the refrigerant flow rate entering the first guide channel h 132 is blocked. The passage of refrigerant in channel 132 has a certain obstructing effect, thereby reducing the refrigerant flow rate entering the first guide channel h 132 per unit time, while increasing the refrigerant flow rate entering the first guide channel g 131 and the first guide channel j 133.

[0077] Similarly, the fourth baffle 145 corresponds to the first guide channel k 134, the first guide channel l 135 and the first guide channel m 136; it can also achieve the above effect, which will not be elaborated here.

[0078] Similarly, the fifth baffle 146 corresponds to the first guide channel n 137, the first guide channel o 138 and the first guide channel p 139; it can also achieve the above effect, which will not be elaborated here.

[0079] In addition, when the upper end of the third baffle 144 rotates to the refrigerant inlet of the first guide channel j 133 and when the upper end of the fourth baffle 145 rotates to the refrigerant inlet of the first guide channel k 134, the refrigerant flow rate entering the first guide channel g 131 and the first guide channel h 132 per unit time decreases, the refrigerant flow rate entering the first guide channel j 133 and the first guide channel k 134 per unit time increases, and the refrigerant flow rate entering the first guide channel k 134 and the first guide channel l 135 per unit time decreases.

[0080] Similarly, when the upper end of the fourth baffle 145 rotates to the refrigerant inlet of the first guide channel m 136 and when the upper end of the fifth baffle 146 rotates to the refrigerant inlet of the first guide channel n 137, the refrigerant flow rate entering the first guide channel k 134 and the first guide channel l 135 per unit time decreases, the refrigerant flow rate entering the first guide channel m 136 and the first guide channel n 137 per unit time increases, and the refrigerant flow rate entering the first guide channel o 138 and the first guide channel p 139 per unit time decreases.

[0081] Understandably, the rotational positions of the third baffle 144, the fourth baffle 145, and the fifth baffle 146 can be adjusted specifically according to the heat dissipation needs of the heat-generating components. The number of airflow channels corresponding to each baffle can also be adjusted specifically according to the position and number of heat-generating components; this is not limited here and will not be elaborated upon.

[0082] The adjacent, side-by-side flow channels allow the refrigerant to flow into each channel via a shorter path after entering through the opening. Compared to dispersed flow channels, this reduces unnecessary detours and bypasses during refrigerant flow, lowering flow resistance and thus minimizing energy loss. This helps maintain stable refrigerant temperature and pressure, enabling the refrigerant to better dissipate heat from the equipment's heat-generating components and preventing overheating and reduced heat dissipation caused by excessive flow distances.

[0083] One baffle corresponds to the refrigerant inlet of multiple first flow channels. When the power unit drives the baffle to rotate, it can precisely guide the refrigerant into the corresponding first flow channel according to the real-time needs of different heat-generating parts of the equipment. For example, when a specific area of ​​the equipment is severely overheating, the power unit drives the baffle to rotate to the refrigerant inlet position of the first flow channel corresponding to that area, allowing more refrigerant to flow into that channel for focused heat dissipation of that heat-generating part. This precise refrigerant distribution method can effectively avoid localized overheating and ensure uniform temperature throughout the equipment.

[0084] By controlling the rotation of the baffle, the disorderly flow of refrigerant into each flow channel can be prevented, avoiding excessive refrigerant waste in areas with low heat generation. In traditional designs, refrigerant may be evenly distributed to all flow channels, resulting in excess refrigerant in areas that do not require significant heat dissipation, while insufficient refrigerant is available in areas that truly need heat dissipation. The design of this application dynamically adjusts the refrigerant distribution according to actual needs, enabling more efficient use of the refrigerant and improving the utilization rate of heat dissipation resources.

[0085] This application also provides a liquid-cooled cabinet, see reference. Figure 7 and Figure 8 As shown, it includes a refrigerant flow guiding device 1; the refrigerant flow guiding device 1 is placed at the bottom of the liquid-cooled cabinet, and the inlet 24 of the liquid-cooled cabinet communicates with the opening 12 of the cavity. The outlet 23 of the liquid-cooled cabinet is located above the inlet 24. (See reference...) Figure 8 As shown, the liquid-cooled cabinet includes a cover 21 and a cabinet 22.

[0086] The functions and effects of the technical features in this technical solution that are similar to or related to the aforementioned technical solution are similar to those in the aforementioned technical solution, and the inventive concept and beneficial effects of this technical solution are similar to those in the aforementioned technical solution, so they will not be repeated here.

[0087] This application also provides a flow guiding method based on a refrigerant flow guiding device, see below. Figure 9 As shown, it includes: S1. Obtain temperature data for at least one heat-generating component of the device; Temperature measurements can be taken at specific locations using measuring devices such as temperature sensors to measure the temperature of parts of the equipment that are prone to heat generation and require close monitoring. The measured temperature values ​​can then be collected and used as a basis for subsequent analysis and judgment.

[0088] S2. Determine whether there is at least one overheated part among the various heating parts of the equipment based on the temperature data of at least one heating part; The acquired temperature data from each heat-generating component is compared with a pre-set temperature threshold. If the temperature data of a heat-generating component exceeds the threshold, that component is determined to be overheated. In this way, it identifies whether any heat-generating component in the device has a temperature exceeding the normal range.

[0089] An overheated part refers to a part of the body that is heated beyond the normal range or a set threshold. The temperature threshold is a pre-set temperature limit value used to determine whether a heated part is overheated.

[0090] S3. In the presence of at least one overheated area, the control power unit drives the corresponding baffle to rotate so that the baffle introduces the refrigerant from the opening of the cavity into the refrigerant inlet of the guide channel corresponding to at least one overheated area.

[0091] When step S2 determines that an overheated area exists, the power unit (such as a motor) is activated. The power unit generates power to drive the baffle to rotate. After the baffle rotates, it changes the flow direction of the refrigerant, allowing the refrigerant flowing out of the cavity opening to be guided into the refrigerant inlet of the guide channel corresponding to the overheated area, thereby enabling the refrigerant to cool the overheated area in a targeted manner.

[0092] The rotation and position of the baffle in specific situations are based on the goal of cooling the overheated parts, and are not limited to the various situations in the above embodiments, such as combinations of the various situations in the above embodiments.

[0093] By acquiring temperature data of heat-generating components and determining whether overheating occurs, the system can accurately identify areas in the equipment that require focused cooling. Then, it can selectively control the flow of refrigerant to these overheated areas, avoiding indiscriminate refrigerant distribution, improving cooling efficiency, and ensuring that critical heat-generating components of the equipment receive timely and effective cooling, thus preventing performance degradation or damage due to overheating.

[0094] Precise cooling methods help maintain equipment operating within a suitable temperature range, reducing various malfunctions and problems caused by excessive temperature, thereby improving the overall stability and reliability of equipment operation and extending the service life of the equipment.

[0095] Compared with traditional all-around cooling methods, this diversion method only supplies refrigerant to the overheated parts that need cooling, reducing unnecessary refrigerant use, lowering energy consumption, and improving the utilization efficiency of cooling resources, thus achieving the dual goals of energy saving and high-efficiency cooling.

[0096] The diversion method described in this application embodiment can be applied to terminal devices such as mobile phones, tablets, wearable devices, in-vehicle devices, augmented reality (AR) / virtual reality (VR) devices, laptops, ultra-mobile personal computers (UMPCs), netbooks, and personal digital assistants (PDAs). This application embodiment does not impose any restrictions on the specific type of terminal device.

[0097] For example, the terminal device may be a station (STAION, ST) in a WLAN, a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA) device, a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a vehicle networking terminal, a computer, a laptop computer, a handheld communication device, a handheld computing device, a satellite wireless device, a wireless modem card, a set-top box (STB), customer premises equipment (CPE), and / or other devices used for communication over a wireless system, as well as next-generation communication systems, such as mobile terminals in 5G networks or mobile terminals in future evolved Public Land Mobile Network (PLMN) networks, etc.

[0098] As an example and not a limitation, when the terminal device is a wearable device, the term "wearable device" can also refer to any device that utilizes wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices worn directly on the body or integrated into a user's clothing or accessories. Wearable devices are not merely hardware devices; they achieve powerful functions through software support, data interaction, and cloud interaction. Broadly defined, wearable smart devices include those with comprehensive functions, large sizes, and the ability to perform complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as those focused on a specific application function that require interaction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0099] Furthermore, S2. Based on the temperature data of at least one heat-generating component, determine whether there is at least one overheated component among the various heat-generating components of the device; including: S21. Based on the temperature data of at least one heating element, determine whether there is at least one heating element whose temperature is greater than or equal to the temperature threshold of the corresponding heating element. If so, determine that there is at least one overheated element.

[0100] After acquiring temperature data from each heat-generating component of the equipment, a pre-set temperature threshold is assigned to each component. This threshold is determined based on a combination of factors, including the equipment's normal operating requirements, material properties, and safety standards. The actual temperature data of each heat-generating component is compared one by one with its corresponding temperature threshold. If any heat-generating component's actual temperature is found to be greater than or equal to its corresponding temperature threshold, then it can be determined that at least one overheated component exists in the equipment.

[0101] By setting corresponding temperature thresholds for each heat-generating component and comparing actual temperature data with these thresholds to determine if an overheating issue exists, the system can accurately identify the location of the overheating problem within the equipment. This avoids potential misjudgments or omissions that might occur with a uniform threshold. For example, different components have different safe temperature ranges due to variations in materials and workload; this method of assigning specific thresholds to different components better reflects the actual operating conditions of the equipment.

[0102] Once an overheated area is identified, the subsequent cooling process can be quickly triggered. For example, the power unit can be controlled to rotate a baffle, directing refrigerant to the overheated area for cooling. This timely response effectively prevents the temperature of the overheated area from rising further, avoiding equipment failure, performance degradation, or even safety accidents caused by overheating, and ensuring the safe and stable operation of the equipment.

[0103] Accurately identifying overheated areas helps in more detailed monitoring and management of equipment operation. By analyzing the overheating status of different heat-generating areas, potential problems can be identified, such as poor local heat dissipation or component aging. This allows for targeted maintenance and improvements, enhancing the overall operating efficiency and reliability of the equipment.

[0105] This application also provides a flow guiding system based on a refrigerant flow guiding device, see reference. Figure 10 As shown, it includes: The acquisition unit is used to acquire temperature data of at least one heat-generating part of the device. The determination unit is used to determine whether there is at least one overheated part among the various heating parts of the device based on the temperature data of at least one heating part. And a control unit, used to control the power unit to rotate the corresponding baffle when there is at least one overheated part, so that the baffle introduces refrigerant from the opening of the cavity into the refrigerant inlet of the guide channel corresponding to at least one overheated part.
