It maintains a certain temperature, humidity, airflow speed, cleanliness, and freshness of the air in the regulated space.

[0003] In existing technologies, liquid cooling is generally used to dissipate heat from electronic components in air conditioners. However, because the liquid cooling medium flows too fast when it enters the liquid cooling pipes from the outside, it often causes excessive vibration of the liquid cooling pipes, which can easily damage the electronic components. Utility Model Content

[0004] The main objective of this utility model embodiment is to provide a liquid cooling heat dissipation structure and an air conditioner, aiming to improve the technical problem of excessive vibration amplitude in the liquid cooling heat dissipation pipeline in the prior art.

[0021] In the aforementioned liquid cooling heat dissipation structure, both the inlet pipe and the outlet pipe are connected to the main pipeline, so that the liquid cooling medium in the main pipeline flows into the liquid cooling heat dissipation structure from the inlet pipe and then flows into the main pipeline through the outlet pipe.

Detailed Implementation

[0032] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0034] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0036] like Figures 1-5 As shown, this utility model provides a liquid cooling heat dissipation structure, which includes an inlet pipe, a heat dissipation pipe 300, and an outlet pipe. The heat dissipation pipe 300 is connected to one end of the inlet pipe, and the outlet pipe is connected to the end of the heat dissipation pipe 300 away from the inlet pipe. A deceleration structure 210 is provided in the inlet pipe to slow down the flow rate of the liquid medium flowing from the inlet pipe to the heat dissipation pipe 300.

[0037] In the liquid cooling structure, the liquid medium flows from the inlet end of the inlet pipe to the outlet end of the inlet pipe, then from the outlet end of the inlet pipe to the inlet end of the cooling pipe 300, then from the inlet end of the cooling pipe 300 to the outlet end of the cooling pipe 300, then from the outlet end of the cooling pipe 300 to the inlet end of the outlet pipe, and finally out of the liquid cooling structure from the outlet end of the outlet pipe.

[0038] It is understandable that by setting a slowing structure 210 in the liquid inlet pipe, the flow rate of the liquid medium flowing from the liquid inlet pipe to the heat dissipation pipe 300 is slowed down, thereby reducing the vibration amplitude of the heat dissipation pipe 300 and improving the service life of electronic components.

[0039] In some embodiments, the deceleration structure 210 may be a baffle provided on the inner wall of the liquid inlet pipe. Multiple baffles are spaced apart along the length of the liquid inlet pipe to block the liquid medium in the liquid inlet pipe, thereby slowing down the flow rate of the liquid medium and thus making the flow rate of the liquid medium entering the heat dissipation pipe 300 lower, so as to avoid causing excessive vibration of the heat dissipation pipe 300.

[0040] In some embodiments, the deceleration structure 210 may also be a wall-type structure used to restrict the channel of the liquid inlet line into a special shape. For example, the deceleration structure 210 is configured such that the liquid inlet line is a first Tesla valve and the valve path of the first Tesla valve is configured to flow in the reverse direction.

[0041] It should be noted that, since the liquid medium in this application flows from the inlet end of the liquid inlet pipe to the outlet end, the first Tesla valve is set up in a relatively conventional manner. Its outlet in the conventional setting is the inlet of this utility model, and its inlet in the conventional setting is the outlet of this utility model. Therefore, when the liquid inlet pipe is the first Tesla valve and the valve is set up in the reverse flow direction, it flows in the forward direction of the Tesla valve relative to the conventional liquid. The liquid medium flows in the reverse direction in the first Tesla valve, and its flow velocity is slower than that of the conventional pipe due to the greater resistance it encounters.

[0042] In some embodiments, the deceleration structure 210 may also be another wall structure used to restrict the channel of the liquid inlet to a special shape. For example, the deceleration structure 210 is configured to make the channel of the liquid inlet gradually widen from the inlet end to the outlet end of the liquid inlet, so as to decelerate the liquid medium.

[0043] In some embodiments, the outlet line is a second Tesla valve, and the valve path of the second Tesla valve is arranged in the forward flow direction.

[0044] It is understandable that by setting the liquid outlet line as the second Tesla valve and arranging it in the same direction as the flow, it can form a mirror structure with the first Tesla valve. Therefore, when assembling the liquid cooling structure, even if the liquid outlet line and the liquid inlet line are installed in reverse, it will not affect the operation of the liquid cooling structure. It can be directly blindly assembled, improving assembly efficiency.

[0045] In some embodiments, the outlet pipeline can also be configured to extend from the inlet end to the outlet end, with the channel of the outlet pipeline gradually narrowing, thereby allowing the liquid medium to flow out of the outlet pipeline more quickly.

[0046] In some embodiments, the liquid inlet pipe and the heat dissipation pipe 300 are connected by a flexible connecting pipe 500.

[0047] Among them, the flexible connecting pipe 500 is a flexible hose.

[0048] It is understandable that when the liquid inlet pipe and the heat dissipation pipe 300 are connected by a flexible hose, the vibration generated by the liquid medium in the liquid inlet pipe is isolated, thus preventing the liquid inlet pipe from causing the heat dissipation pipe 300 to vibrate, thereby reducing the vibration amplitude of the heat dissipation pipe 300.

[0049] In some embodiments, the liquid outlet pipe and the heat dissipation pipe 300 are connected by a flexible connecting pipe 500.

[0050] Among them, the flexible connecting pipe 500 is a flexible hose.

[0051] Referring to the above embodiments, the flexible connecting pipe 500 can isolate the vibration between the liquid outlet pipe and the heat dissipation pipe 300, and reduce the amplitude of the heat dissipation pipe 300.

[0052] In some embodiments, the liquid inlet pipe and the heat dissipation pipe 300 are connected by a flexible connecting pipe 500, and the liquid outlet pipe and the heat dissipation pipe 300 are connected by a flexible connecting pipe 500. The flexible connecting pipe 500 is a plastic hose.

[0053] In some embodiments, a plurality of rectifiers 321 are provided inside the heat dissipation pipe 300, and the plurality of rectifiers 321 are all arranged parallel to the length direction of the heat dissipation pipe 300.

[0054] It is understandable that rectifier 321 in heat dissipation pipe 300 can rectify the liquid medium in heat dissipation pipe 300, making the liquid medium flow smoothly and reducing the vibration of heat dissipation pipe 300; at the same time, it can improve the heat dissipation effect of heat dissipation pipe 300 to a certain extent; in addition, rectifier 321 can also reduce the flow velocity of liquid medium in heat dissipation pipe 300 to a certain extent, thereby reducing the amplitude of vibration of heat dissipation pipe 300.

[0055] In some embodiments, the heat dissipation pipe 300 includes an inlet 310, a heat dissipation section 320, and an outlet 330 connected in sequence. The inlet 310 is connected to the liquid inlet pipe, and the outlet 330 is connected to the liquid outlet pipe. The heat dissipation section 320 is provided with a plurality of rectifiers 321, and the plurality of rectifiers 321 are all arranged parallel to the length direction of the heat dissipation section 320.

[0056] The heat dissipation part 320 is used to contact the electronic components, thereby realizing the heat dissipation part 320 as a heat exchange medium between the electronic components and the liquid cooling medium, thus realizing the heat exchange of the electronic components.

[0057] After the liquid medium enters the heat dissipation pipe 300, it flows through the inlet 310, the heat dissipation section 320 and the outlet 330 in sequence. That is, the liquid medium flows along the length direction of the inlet 310, the length direction of the heat dissipation section 320 and the length direction of the outlet 330. Therefore, when the rectifier plate 321 is parallel to the length direction of the heat dissipation section 320, its effect of hindering the flow rate of the liquid medium can be minimized, and the heat dissipation effect of the heat dissipation section 320 can also be improved.

[0058] It is understandable that, considering the beneficial effects of setting rectifier 321 in the heat dissipation pipe 300, the liquid medium in the heat dissipation section 320 can be rectified, making the liquid medium flow smoothly and reducing the vibration of the heat dissipation pipe 300; at the same time, the heat dissipation effect of the heat dissipation section 320 can be improved to a certain extent; in addition, rectifier 321 can also reduce the flow rate of the liquid medium in the heat dissipation section 320 to a certain extent, thereby reducing the amplitude of vibration of the heat dissipation pipe 300.

[0059] In some embodiments, the heat dissipation part 320 is a square tube with a heat dissipation wall on one side. The heat dissipation wall is used to directly contact electronic components. The rectifier plate 321 is connected to the heat dissipation wall, which can increase the contact area between the liquid medium and the heat dissipation part 320, which is equivalent to increasing the heat exchange area between the heat dissipation wall and the liquid medium, thereby improving the heat dissipation effect of the heat dissipation part 320.

[0060] In some embodiments, the inlet 310 is an arc-shaped pipe, and its arc-shaped section is mainly used to allow the liquid cooling medium in the inlet 310 to smoothly enter the heat dissipation section 320, so as to avoid the liquid medium from being impacted in the heat dissipation section 320 due to excessive turning angle (such as 90°), which would increase the vibration amplitude of the heat dissipation pipe 300.

[0061] In some embodiments, the outlet section 330 is an arc-shaped pipe. The arc-shaped section is mainly used to allow the liquid cooling medium in the heat dissipation section 320 to smoothly enter the outlet section 330, avoiding excessive turning angle (such as 90°) which would cause the liquid medium to impact in the outlet section 330 and increase the vibration amplitude of the heat dissipation pipe 300.

[0062] In some embodiments, the inlet 310 is an arc-shaped pipe and the outlet 330 is an arc-shaped pipe.

[0063] In some embodiments, a plurality of heat dissipation fins 322 are provided on the outer wall of the heat dissipation pipe 300, and the plurality of heat dissipation fins 322 are spaced apart along the length direction of the heat dissipation pipe 300.

[0064] It should be noted that the heat dissipation fins 322 can be installed on any side wall of the heat dissipation pipe 300 except for the side wall that is in contact with the electronic components.

[0065] It is understandable that by setting heat dissipation fins 322 on the heat dissipation pipe 300, the heat dissipation area of ​​the heat dissipation pipe 300 can be increased, thereby improving the heat dissipation effect of the heat dissipation pipe 300.

[0066] In some embodiments, an air conditioner is also provided, which includes the liquid-cooled heat dissipation structure described above. Since the air conditioner includes at least some or all of the embodiments of the liquid-cooled heat dissipation structure described above, the air conditioner has at least the beneficial effects of some or all of the embodiments described above, which will not be elaborated here.

[0067] The air conditioner also includes a main pipe 100, in which a liquid cooling medium flows. The inlet pipe 200 and outlet pipe 400 of the liquid cooling heat dissipation structure are both connected to the main pipe 100, so that the liquid cooling medium in the main pipe 100 flows into the liquid cooling heat dissipation structure from the inlet pipe 200 and then flows into the main pipe 100 through the outlet pipe 400.

[0068] The inlet pipe 200 is located near the inlet end of the main pipe 100, and the outlet pipe 400 is located near the outlet end of the main pipe 100. That is, after using the liquid medium in the main pipe 100, the liquid medium that was exchanged for heat in the radiator flows back to the main pipe 100.

[0069] In some embodiments, the angle between the inlet pipe 200 and the main pipe 100 is greater than 0° and less than 75°.

[0070] It is understandable that limiting the angle between the inlet pipe 200 and the main pipe 100 within this range can prevent the liquid medium from impacting the inlet pipe 200 when it flows into the inlet pipe 200 due to an excessively large angle (such as 90°), which would cause excessive vibration of the liquid cooling structure.

[0071] In some embodiments, the angle between the outlet pipe 400 and the main pipe 100 is greater than 0° and less than 75°.

[0072] It is understandable that limiting the angle between the outlet pipe 400 and the main pipe 100 within this range can prevent the liquid medium from impacting the pipe and causing the liquid cooling structure to vibrate when it flows into the main pipe 100 due to an excessively large angle (such as 90°).

[0073] In some embodiments, the angle between the inlet pipe 200 and the main pipe 100 is greater than 0° and less than 75°; the angle between the outlet pipe 400 and the main pipe 100 is greater than 0° and less than 75°.

[0074] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made based on the contents of the present utility model specification and drawings under the application concept of the present utility model, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
