Description

Technical Field

[0001] The utility model relates to the technical field of liquid leakage detection, in particular to a liquid leakage detection device, a water-cooled radiator and a computer. Background Art

[0002] Currently, some computers on the market use water-cooled radiators. Among them, some water-cooled radiators are not only equipped with some sealing structures at the pipe interfaces to prevent water leakage, but also have leakage detection devices. Paint that changes color when exposed to water is set at the parts prone to leakage. When a part leaks, liquid of a certain color can be seen flowing out, and users can use this to determine whether there is a leakage.

[0003] However, this solution has great limitations, as it requires coatings to be applied to various leak-prone areas. Furthermore, if leakage occurs in other areas, the above solution becomes ineffective, and users may suffer huge losses due to failure to detect the leakage problem in time. Utility Model Content

[0004] The main purpose of the utility model is to provide a liquid leakage detection device, a water-cooled radiator and a computer, aiming to improve the detection comprehensiveness of the liquid leakage detection device.

[0005] To achieve the above object, the utility model provides a liquid leakage detection device, which is applied to a water-cooled radiator of a computer. The liquid leakage detection device comprises:

[0006] Mounting seat;

[0007] A negative pressure bag, the negative pressure bag is connected to the mounting seat, and a negative pressure cavity is formed in the negative pressure bag;

[0008] An air pressure detection component is installed on the mounting seat, and the air pressure detection component has a detection end, and the detection end is arranged in the negative pressure cavity.

[0009] In some embodiments of the present invention, the mounting seat includes a seat body and a pressure ring, the negative pressure bag is provided with an opening, the opening of the negative pressure bag abuts against the mounting seat, and the pressure ring is installed on the seat body and squeezes and seals the opening.

[0010] In some embodiments of the present invention, the negative pressure bag is provided with a flange at the periphery of the opening, and the flange is clamped between the pressure ring and the seat body.

[0011] In some embodiments of the present invention, a side of the pressure ring facing the flange is provided with a step surface, and the step surface cooperates with the flange.

[0012] In some embodiments of the present invention, a positioning rib is disposed on the top surface of the seat body, and the flange is pressed against the positioning rib.

[0013] In some embodiments of the present invention, the seat body is provided with a through hole, the pressure ring is provided with a threaded hole, and the screw connection member passes through the through hole and is connected to the threaded hole.

[0014] In some embodiments of the present invention, a positioning protrusion is provided on the outer periphery of the pressure ring facing the seat body, and a positioning notch is provided on the outer periphery of the seat body, and the positioning protrusion cooperates with the positioning notch.

[0015] In some embodiments of the present invention, the liquid leakage detection device further comprises a pressure cylinder, the pressure cylinder is provided with a cavity and a pipe interface connected to the cavity, and the mounting seat is mounted on the inner wall of the cavity.

[0016] The utility model also provides a water-cooled radiator, comprising the above-mentioned liquid leakage detection device, wherein the liquid leakage detection device comprises:

[0017] Mounting seat;

[0018] A negative pressure bag, the negative pressure bag is connected to the mounting seat, and a negative pressure cavity is formed in the negative pressure bag;

[0019] An air pressure detection component is installed on the mounting seat, and the air pressure detection component has a detection end, and the detection end is arranged in the negative pressure cavity.

[0020] The utility model also provides a computer, comprising the water-cooling radiator.

[0021] In the technical solution of the utility model, the leakage detection device can be installed in the water-cooling circulation pipeline. When there is no leakage, the air pressure in the negative pressure bag and the hydraulic pressure in the water-cooling circulation pipeline are maintained in a negative pressure balance state, the negative pressure bag does not deform, the size of the internal space of the negative pressure bag remains unchanged, and the air pressure detected by the air pressure sensor remains unchanged. When leakage occurs, gas is mixed into the water-cooling circulation pipeline, and the pressure approaches atmospheric pressure. The negative pressure bag shrinks under the action of the pressure difference, and its internal space shrinks, and the air pressure detected by the air pressure sensor increases. The air pressure sensor can be connected to a computer control system to send a detection signal to the control system. After receiving the detection signal, the control system can prompt the user of the leakage problem through a display or a speaker or other device.

[0022] Through the above scheme, no matter which part of the water-cooling circulation pipeline has a leakage problem, the leakage detection device can detect it and give feedback in time to achieve comprehensive detection, and the leakage detection device can be reused. In addition, the leakage detection device has high detection sensitivity. Even if the leakage hole in the water circulation pipeline is relatively small, it will cause the pressure in the water circulation pipeline to approach the atmospheric pressure in a short time, which will cause the negative pressure bag to deform due to the pressure difference between the inside and outside, so that its internal space is reduced, and the air pressure detected by the air pressure sensor increases. Because the water-cooling circulation pipeline is under negative pressure, no leakage will occur at the tiny leakage hole. It is also because of the negative pressure in the water-cooling circulation pipeline that when the coolant is heated or frozen and expanded, the force on the pipeline is small, which can effectively reduce the risk of leakage.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0032] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0033] See also Figures 1 to 3 The utility model proposes a liquid leakage detection device 100, which is applied to a water-cooled radiator of a computer. The liquid leakage detection device 100 includes a mounting seat 20, a negative pressure bag 40 and an air pressure detection component 30, wherein the negative pressure bag 40 is connected to the mounting seat 20, and a negative pressure cavity 41 is formed in the negative pressure bag 40; the air pressure detection component 30 is installed on the mounting seat 20, and the air pressure detection component 30 has a detection end 31, and the detection end 31 is arranged in the negative pressure cavity 41.

[0034] In the technical solution of the utility model, the leakage detection device 100 can be installed in the water-cooling circulation pipeline. When there is no leakage, the air pressure in the negative pressure bag 40 and the hydraulic pressure in the water-cooling circulation pipeline are maintained in a negative pressure balance state, the negative pressure bag 40 does not deform, the size of the internal space of the negative pressure bag 40 remains unchanged, and the air pressure detected by the air pressure sensor remains unchanged. When leakage occurs, gas is mixed into the water-cooling circulation pipeline, and the pressure approaches atmospheric pressure. The negative pressure bag 40 shrinks under the action of the pressure difference, and its internal space shrinks, and the air pressure detected by the air pressure sensor increases. The air pressure sensor can be connected to a computer control system to send a detection signal to the control system. After receiving the detection signal, the control system can prompt the user of the leakage problem through a display or a speaker or other device.

[0035] Through the above scheme, no matter which part of the water-cooling circulation pipeline has a leakage problem, the leakage detection device 100 can detect it and give feedback in time, so as to achieve comprehensive detection, and the leakage detection device 100 can be reused. In addition, the leakage detection device 100 has high detection sensitivity. Even if the leakage hole in the water circulation pipeline is relatively small, it will cause the pressure in the water circulation pipeline to approach the atmospheric pressure in a short time, thereby causing the negative pressure bag 40 to deform due to the pressure difference between the inside and the outside, so that its internal space is reduced, and the air pressure detected by the air pressure sensor increases. Since the water-cooling circulation pipeline is under negative pressure, no leakage will occur at the tiny leakage hole. It is also because of the negative pressure in the water-cooling circulation pipeline that when the coolant is heated or frozen and expanded, the force on the pipeline is small, thereby effectively reducing the risk of leakage.

[0036] The negative pressure bag 40 is made of waterproof material and is generally made of elastic material, such as rubber, silicone, etc., which is easy to deform and can maintain a certain shape. Of course, it can also be made of flexible material, such as plastic film, and is set according to specific circumstances, which is not limited here.

In this arrangement, the negative pressure bag 40 is clamped by the pressure ring 22 and the seat body 21, and the stability and sealing are good, which can prevent the coolant from penetrating into the negative pressure chamber 41 and affecting the negative pressure sensor.

[0039] There are many specific implementations of the pressure ring 22 and the seat body 21 squeezing and sealing the opening 43. In some embodiments of the present utility model, the top surface of the mounting seat 20 is convexly provided with a mounting cone, the opening 43 of the negative pressure bag 40 is sleeved on the outside of the mounting cone, and the negative pressure bag 40 is squeezed between the pressure ring 22 and the mounting cone.

[0040] In some other embodiments of the present invention, the negative pressure bag 40 is provided with a flange 42 on the outer periphery of the opening 43, and the flange 42 is clamped between the pressure ring 22 and the seat body 21, so that the assembly sealing effect is better.

The stability and sealing are higher, and the negative pressure bag 40 can be prevented from being misplaced during installation.

[0042] Furthermore, in some embodiments of the present invention, the top surface of the seat body 21 is provided with a positioning rib 211, and the flange 42 is pressed against the positioning rib 211. This can improve the sealing performance between the contact surface of the flange 42 and the seat body 21.

The connection is stable, and in addition, the cover plate is connected through the connecting ring 214, so that a certain interval is formed between the bottom surface of the seat body 21 and the cover plate, which can accommodate the head of the screw connection piece, and the structural arrangement is relatively reasonable. The sealing structure 60 can be made of sealant or a sealing gasket, which is not specifically limited here.

[0048] Furthermore, in some embodiments of the present invention, a relief hole 215 is provided on the bottom surface of the seat body 21, and the air pressure sensor includes an electrical terminal, which passes through the relief hole 215 to facilitate electrical connection with external equipment.

[0049] In some embodiments of the present invention, the liquid leakage detection device 100 further includes a tee pipe 50, one of the pipe openings of the tee pipe 50 is connected to the pipe interface 102. In this way, during assembly, the joints of the water circulation pipeline can be connected to the other two pipe openings of the tee pipe 50 respectively, and the liquid leakage detection device 100 can be applied to pipelines that are not provided with a pipe opening for docking with the pipe interface 102, and has better adaptability.

[0050] Furthermore, in some embodiments of the present invention, the three-way pipe 50 includes a connecting pipe portion 51 and a detection pipe portion 52, one end of the detection pipe portion 52 is connected to the peripheral wall of the connecting pipe portion 51, and the inner diameter of the end of the detection pipe portion 52 close to the connecting pipe portion 51 is smaller than the inner diameter of the connecting pipe portion 51.
