Description

Technical Field

[0001] The invention relates to the field of computer heat dissipation equipment, and in particular to a spliced ​​leak detection water cooling radiator structure for a computer and a control method thereof. Background Art

[0002] Computer water cooling system refers to a physical circulation system that uses the large specific heat capacity of water to dissipate heat from heat-prone modules such as the central processing unit and graphics card in a relatively closed computer host. Computer water cooling system has multiple pipes. The volume (the so-called "volume" includes the sum of the volume of physical components and the volume of pipes) is large and the structure is relatively complex.

[0003] Existing water cooling radiators are generally connected to water pumps separately to achieve liquid circulation. However, some heat-generating components (such as CPUs and graphics cards) require separate water cooling radiators and water pumps to dissipate heat. As a result, the components inside the chassis are relatively messy, affecting the aesthetics of the existing transparent chassis and occupying a large amount of space.

[0004] When products need to be connected in series, turns (requiring multiple elbows) and hose settings often occur, so the design is complicated and prone to problems such as flow distortion, abnormal noise and leakage, and the aesthetics is low. The biggest problem is that the hose will extend, otherwise leakage is likely to occur at the joint, affecting the stability of use. Summary of the invention

[0005] The main purpose of the present invention is to propose a spliced ​​leak detection water cooling row structure for computers and its control method, aiming to improve the existing water cooling row structure so that the water cooling rows can be conveniently spliced, the pipe length is short, the installation is simple, the lateral leakage is reduced, the product stability is improved, and the appearance is higher.

[0006] To achieve the above-mentioned purpose, the present invention proposes a spliced ​​leak detection water cooling row structure for a computer and a control method thereof, comprising:

[0007] A water drainage assembly, wherein at least two water drainage assemblies are provided, and the water drainage assemblies include a first water drainage assembly and a second water drainage assembly, wherein the first water drainage assembly is provided with a first flow channel, and the second water drainage assembly is provided with a second flow channel, and the first flow channel and the second flow channel are connected and surrounded by a water pump to form a circulation flow channel;

[0008] The first water row assembly is provided with at least one set of first input channel and first output channel, and the second water row assembly is provided with at least one set of second input channel and second output channel.

[0009] The first water row assembly is extended with a positioning seat, and the upper wall of the positioning seat is arranged opposite to the outer side wall of the second water row assembly.

[0010] The first output channel and the second input channel are connected via a first positioning tube.

[0011] The first input channel and the second output channel are connected via a second positioning tube or are connected to two ends of the water pump;

[0012] The first flow channel and / or the second flow channel is provided with a leak detection device. When leakage occurs in the circulating flow channel, the internal pressure of the fluid in the circulating flow channel decreases. The leak detection device is connected to a control device. The control device is provided with a filter module. When the filter module exceeds a predetermined threshold, the control device issues an early warning and shuts down the water pump.

[0013] In the actual design, the installation and connection of the first water row assembly and the second water row assembly are facilitated by the arrangement of the positioning seat and the relative arrangement of the upper wall of the positioning seat and the outer wall of the second water row assembly. During installation, the first positioning tube and the second positioning tube of the second water row assembly can be directly inserted into the positioning seat. The installation method can be designed according to actual needs, such as a sealing buckle or a clamp or other fixing method, so as to realize the connection between the first flow channel and the second flow channel to form a circulating water channel.

[0014] At the same time, in order to avoid leakage in the circulation channel, a leak detection device is set in the first channel and / or the second channel, so that the internal pressure of the circulation channel can be detected, and the fluid pressure can be monitored in time. By setting the filter module, the possibility of product leakage can be reduced (the filter device can be used to monitor static pressure and dynamic pressure, and use a constant value to judge the filtering abnormality threshold), thereby achieving stable pressure judgment and improving the stability of the water cooling radiator.

[0015] In actual design, 240 radiators and 360 radiators or larger sizes can be fluidly spliced, thereby improving space utilization and avoiding clutter.

[0016] The structure can be applied to the turning position in the computer case, so as to achieve neat pipelines. At the same time, the first jack and the second jack and the first positioning tube and the second positioning tube can be applied to the connection of special-shaped cases through the inclination angle setting (for example, 90 degrees, 60 degrees), thereby improving the applicability of the product. The first positioning tube and the second positioning tube can be hoses (with support or the joint position is a hard structure) or hard structures.

[0017] A control method for a spliced ​​leak detection water cooling row structure for a computer, characterized in that: it comprises the above-mentioned spliced ​​leak detection water cooling row structure for a computer, a plurality of water pumps and water cooling heads as an integrated module and a leak detection device, wherein the water pump is provided with a servo motor,

[0018] The servo motor and the leak detection device are respectively connected to the control device, and the circulation channel is a closed cavity;

[0019] The leak detection device is provided with a plurality of positions respectively located in the circulation channel, and N detection devices obtain N fluid internal pressure data;

[0020] When the fluid has a static internal pressure, the fluid internal pressure data is a constant pressure, and the corresponding N detection devices are consistent or have a constant difference.

[0021] When leakage occurs in the circulation channel, the filtering module compares the original internal pressure data, and the fluid internal pressure data is less than a predetermined threshold;

[0022] When the fluid has a dynamic internal pressure, the fluid circulates and the internal pressure of the fluid fluctuates, thereby obtaining fluctuating fluid internal pressure data.

[0023] The filtering module compares the raw fluctuating fluid data, the raw fluctuating fluid data having a maximum threshold and a minimum threshold,

[0024] When a detection device reaches a maximum threshold, the control device adjusts the rotation speed of the adjacent servo motor, and the rotation speed is increased or decreased to ensure that the internal pressure of the circulation channel is consistent or at a fluctuating value. When the fluctuation value continues to decrease, the filter device issues an early warning.

[0025] When a minimum threshold value appears in a certain detection device, the rotation speed of the adjacent servo motor is adjusted, and the internal pressure of the circulation channel cannot rise to the original fluctuating fluid data, it is judged as a leakage.

[0026] In actual design, the fluid in the circulation channel is divided into two situations, namely static and flowing. When multiple cooling ports and water pumps are integrated into a module, it is bound to produce a pressure difference in the fluid. Therefore, when a difference occurs locally, it will affect the overall fluid flow rate. When the local fluid flow rate is greater than the predetermined value, it may cause the internal pressure to rise, and then cause the pipe body or interface to detach or leak.

[0027] Therefore, how to ensure the consistency of the internal pressure of the fluid is the key to the design. At the same time, while ensuring the flow rate of the fluid, it is also necessary to avoid internal pressure differences. The above control method can effectively ensure the circulation cooling of the heating element and the stability of use.

[0028] In the embodiments, the faster the flow rate, the more heat it takes away. Therefore, the maximum threshold of the internal pressure of the circulation channel must be ensured while ensuring the circulation stability.

[0029] Especially for the above-mentioned multiple water drainage assembly splicing structure, the stability of the connection between the first positioning tube and the second positioning tube is the key to the design.

[0030] At the same time, the snap-fit ​​structure of the sealing ring can ensure sealing while avoiding installation troubles. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] like Figures 1 to 5 As shown, a spliced ​​leak detection water cooling row structure for a computer and a control method thereof include:

[0048] A water row assembly, wherein at least two water row assemblies are provided, and the water row assemblies include a first water row assembly 11 and a second water row assembly 12, wherein the first water row assembly is provided with a first flow channel 110, and the second water row assembly 12 is provided with a second flow channel 120, and the first flow channel 110 and the second flow channel 120 are connected and surrounded by a water pump 2 to form a circulation flow channel;

[0049] The first water row assembly 11 is provided with at least one set of first input channel 11a and first output channel 11b, and the second water row assembly 12 is provided with at least one set of second input channel 12a and second output channel 12b.

[0050] The first water row assembly 11 is extended with a positioning seat 31, and the upper wall of the positioning seat 31 is arranged opposite to the outer side wall 32 of the second water row assembly 12.

[0051] The first output channel 11b and the second input channel 12a are connected through a first positioning tube 32a.

[0052] The first input channel 11a and the second output channel 12b are connected via a second positioning tube 32b or connected to both ends of the water pump 2;

[0053] The first flow channel 110 and / or the second flow channel 120 is provided with a leak detection device. When leakage occurs in the circulation flow channel, the internal pressure of the fluid in the circulation flow channel decreases. The leak detection device is connected to a control device. The control device is provided with a filter module. When the filter module exceeds a predetermined threshold, the control device issues an early warning and shuts down the water pump 2.

[0054] In the actual design, the arrangement of the positioning seat 31 and the relative arrangement of the upper wall of the positioning seat 31 and the outer wall 32 of the second water row assembly 12 facilitate the installation and connection of the first water row assembly 11 and the second water row assembly 12. During installation, the first positioning tube 32a and the second positioning tube 32b of the second water row assembly 12 can be directly inserted into the positioning seat 31. The installation method can be designed according to actual needs, such as a sealing buckle or a clamp or other fixing method, so as to realize the connection between the first flow channel 110 and the second flow channel 120 to form a circulating water channel.

[0055] At the same time, in order to avoid leakage in the circulation channel, a leak detection device is set in the first channel 110 and / or the second channel 120, so that the internal pressure of the circulation channel can be detected, and the fluid pressure can be monitored in time. By setting the filter module, the possibility of product leakage can be reduced (the filter device can be used to monitor static pressure and dynamic pressure, and use a constant value to determine the filtering abnormality threshold), thereby achieving stable pressure judgment and improving the stability of the water cooling radiator.

[0056] In actual design, 240 radiators and 360 radiators or larger sizes can be fluidly spliced, thereby improving space utilization and avoiding clutter.

[0057] Specifically, when the first input channel 11a and the second output channel 12b are connected through the second positioning tube 32b,

[0058] The first water drainage assembly 11 and / or the second water drainage assembly 12 is provided with at least one set of water inlet 21 and water outlet 22.

[0059] The water inlet 21 and the water outlet 22 are connected to the water pump 2 or the water cooling head.

[0060] In a specific design, multiple groups of water inlets 21 and water outlets 22 can be provided according to different requirements, and fluid circulation can be achieved through one or more groups of water pumps 2 (preferably one group, with a larger power to output a larger flow pressure to the fluid);

[0061] In specific use, the water pump 2 and the water cooling head can be designed as an integrated whole, or multiple groups of water cooling heads can be provided, so that multiple groups of heating elements can be cooled separately, thereby improving the applicability of the equipment.

[0062] In an embodiment of the present invention, the positioning seat 31 is provided with at least one group of first sockets 31a and second sockets, and the first positioning tube 32a and the second positioning tube 32b are respectively inserted into the first socket 31a and the second socket, that is, the first input channel 11a and the first output channel 11b, the second input channel 12a and the second output channel 12b.

[0063] The first plug hole and the second plug hole preferably adopt an extended structure, thereby increasing the contact area with the first positioning tube 32a and the second positioning tube 32b.

[0064] Specifically, the first positioning tube 32 a and the second positioning tube 32 b are integrally formed with the second water drain assembly 12 or are detachably installed.

[0065] For example, one-piece injection molding or a conventional sealing installation structure, such as a threaded, plug-in, etc. structure.

[0066] In the embodiment of the present invention, the detachable installation is a threaded connection, a snap-on connection or a rivet fixation.

[0067] Specifically, the first positioning tube 32a and the second positioning tube 32b are provided with sealing rings at the ends away from the second water discharge assembly 12, and the sealing rings 4 are fixed by a slot or glued or elastically fixed, thereby ensuring the stability and sealing of the combination with the first plug hole 31a and the second plug hole, and are fixed by interference fit.

[0068] In the embodiment of the present invention, the water pump 2 and the water cooling head are an integrated module, and the integrated module is connected in series with the circulation channel through the water inlet 21 and the water outlet 22. The advantage of using an integrated module is that it can ensure that the fluid in the circulation channel will not have a fluid pressure difference, and at the same time, the rotation speed of the water pump 2 can be adjusted according to the actual internal pressure of the fluid, thereby avoiding the problem of local overspeed or local overslowness of the circulation channel caused by local flow rate differences, and improving the flow stability of the circulation channel.

[0069] Specifically, the outer side wall 32 of the second water row assembly 12 is a bottom wall.

[0070] The first water row assembly 11 and the second water row assembly 12 are both provided with a partition 5 at the fluid connection position. The fluid connection position includes between the water inlet 21 and the water outlet 22, between the first input channel 11a and the first output channel 11b, and between the second input channel 12a and the second output channel 12b;

[0071] The partition 5 can be provided to connect and conduct external devices, wherein the leak detection device can also be installed between the water inlet 21 and the water outlet 22, thereby facilitating installation without the need for a special embedded structure to affect the original layout of the water cooling radiator.

[0072] Specifically, the leak detection device includes an adapter and a sensor arranged inside the adapter, and the sensor is a water flow sensor, a pressure sensor, a flow sensor, or a water level sensor.

[0073] In one of the embodiments, the positioning seat can be detachably installed on the water drain component. For example, the positioning seat of different lengths or positions can be replaced according to different assembly environments. Therefore, the water drain component can be distributed in a closed loop along the cavity of the chassis, thereby realizing an integrated water drain design.

[0074] A control method for a spliced ​​leak detection water cooling row structure for a computer, comprising the above-mentioned spliced ​​leak detection water cooling row structure for a computer, a plurality of water pumps 2 and a water cooling head as an integrated module and a leak detection device, wherein the water pump 2 is provided with a servo motor,

[0075] The servo motor and the leak detection device are respectively connected to the control device, and the circulation channel is a closed cavity;

[0076] The leak detection device is provided with a plurality of positions respectively located in the circulation channel, and N detection devices obtain N fluid internal pressure data;

[0077] When the fluid has a static internal pressure, the fluid internal pressure data is a constant pressure, and the corresponding N detection devices are consistent or have a constant difference.

[0078] When leakage occurs in the circulation channel, the filtering module compares the original internal pressure data, and the fluid internal pressure data is less than a predetermined threshold;

[0079] When the fluid has a dynamic internal pressure, the fluid circulates and the internal pressure of the fluid fluctuates, thereby obtaining fluctuating fluid internal pressure data.

[0080] The filtering module compares the raw fluctuating fluid data, the raw fluctuating fluid data having a maximum threshold and a minimum threshold,

[0081] When a detection device reaches a maximum threshold, the control device adjusts the rotation speed of the adjacent servo motor, and the rotation speed is increased or decreased to ensure that the internal pressure of the circulation channel is consistent or at a fluctuating value. When the fluctuation value continues to decrease, the filter device issues an early warning.

[0082] When a minimum threshold value appears in a certain detection device, the rotation speed of the adjacent servo motor is adjusted, and the internal pressure of the circulation channel cannot rise to the original fluctuating fluid data, it is judged as a leakage.

[0083] In actual design, the fluid in the circulation channel is divided into two situations, namely static and flowing. When multiple cooling ports and water pump 2 are integrated into a module, it is bound to produce a pressure difference in the fluid. Therefore, when a difference occurs locally, it will affect the overall fluid flow rate. When the local fluid flow rate is greater than the predetermined value, it may cause the internal pressure to rise, and then cause the pipe body or interface to detach or leak.

[0084] Therefore, how to ensure the consistency of the internal pressure of the fluid is the key to the design. At the same time, while ensuring the flow rate of the fluid, it is also necessary to avoid internal pressure differences. The above control method can effectively ensure the circulation cooling of the heating element and the stability of use.

[0085] In the embodiments, the faster the flow rate, the more heat it takes away. Therefore, the maximum threshold of the internal pressure of the circulation channel must be ensured while ensuring the circulation stability.

[0086] Especially for the above-mentioned multiple water drainage assembly splicing structure, the stability of the connection between the first positioning tube 32a and the second positioning tube 32b is the key to the design.

[0087] At the same time, the snap-fit ​​structure of the sealing ring 4 can ensure sealing while avoiding installation troubles.

[0088] The leak detection device can ensure the consistency of the flow rate and flow pressure of the fluid, thereby reducing the problem of excessive or insufficient pressure. The preferred internal pressure can be set to reduce the problem of overpressure or overflow.

[0089] It ensures the problem of unstable heat dissipation when multiple cold heads are connected in series with the circulating flow channel (the essence of which is to solve the problem of water cooling system preventing local water flow or water resistance from being too large, resulting in leakage). That is, sometimes, the local pipe is bent (the location connected to the water pump). When the local series structure is over-pressured, it is easy to cause joint leakage or detachment, thus ensuring the stability of the computer cooling system.

[0090] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
