Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of server fire protection, and in particular to an immersion-type server fire extinguishing device. Background Art
[0002] Liquid cooling is a technology introduced to solve the problem of high-density heat dissipation in servers. Liquid-cooled servers are products developed under this technology to solve the problems of a large number of users. Liquid-cooled servers are server systems that use liquid cooling technology to reduce server temperature. Traditional servers usually use air cooling to dissipate heat, while liquid-cooled servers use liquid media to directly contact the heat dissipation components to effectively absorb and remove the generated heat.
[0003] The heat generating components are directly immersed in the coolant, and the heat generated by the operation of the server and other equipment is removed by the circulation of the liquid. Immersion liquid cooling is a typical direct contact liquid cooling. Since the heat generating components are in direct contact with the coolant, the heat dissipation efficiency is higher and the noise is lower, which can solve the problem of high heat prevention. Immersion liquid cooling is divided into two-phase liquid cooling and single-phase liquid cooling, and the heat dissipation method can be in the form of dry cooler and cooling tower.
[0004] In the prior art, when a server has a short circuit or other characteristics, it is more likely to cause a fire risk. Some of the cooling materials that use grease are easy to burn under certain conditions. Generally, a fire detection tube is arranged on the top of the server. The fire extinguishing medium is sprayed from the fire detection tube to fill the top of the grease to achieve the fire extinguishing effect. However, as the fire detection tube ruptures, the fire extinguishing medium is sprayed from different positions of the fire detection tube. The uneven spraying will cause the flow of the sprayed fire extinguishing medium to be unstable, thereby causing the fire detection tube to shake. The shaking or unstable spraying of the fire detection tube will cause the spraying direction of the fire extinguishing medium to deviate, and it cannot be accurately sprayed to the fire source, thus affecting the fire extinguishing effect. Utility Model Content
[0005] In order to solve the above technical problems, the utility model uses mounting parts to mount different sections of the fire detection tube on the top of the box. The specific technical solution is as follows:
[0006] An immersion server fire extinguishing device includes a box body in which a server is installed, a coolant for immersing the server is provided inside the box body, a fire detection tube coiled on the inner top wall of the box body and located above the coolant; and a mounting member installed on the top end of the box body and fixing different sections of the coiled fire detection tube to the box body.
[0007] Preferably, the mounting member comprises a plurality of fixing cards mounted on the top wall of the box body, and an end of the fixing card facing the server forms an arc groove for clamping the fire detection tube.
[0008] Preferably, a panel is installed on the top surface of the box body, and the overlapping part of the fire detection tube and the panel is installed on the panel.
[0009] Preferably, a plurality of arc grooves are formed at one end of the panel facing the server, and the arc grooves are clamped tightly to the outer wall of the fire detection tube.
[0010] Preferably, the inner top wall of the box body is provided with a groove along the winding direction of the fire detection tube, and the part of the fire detection tube away from the server is located in the groove of the box body.
[0011] It can be seen from the above technical solutions that the utility model has the following beneficial effects:
[0012] The utility model adopts a mounting piece to mount the fire detection tube on the top of a box body, arranges different sections for the fire detection tube, and fixes the different sections of the fire detection tube on the box body respectively, thereby increasing the fixing effect between the different sections of the fire detection tube and reducing the shaking of the fire detection tubes of different sections, so as to prevent the shaking of the fire detection tube or unstable spraying from causing the deviation of the spraying direction of the fire extinguishing medium.
[0013] By fixing the fire detection tube with a fixing card and a panel, the installation method of the fire detection tube is further improved, which facilitates the subsequent disassembly. At the same time, it also ensures that the panel has a limiting effect on the fire detection tube when the fire detection tube is sprayed, greatly reducing the shaking effect of the middle part of the fire detection tube.
[0014] The top of the box wraps the three sides of the fire detection tube by the top wall of the box, and the overall position of the fire detection tube is restricted during spraying, which further reduces the jitter of the fire detection tube caused by spraying and improves the accuracy of spraying.

[0019] The following is a detailed description of the present invention in conjunction with the accompanying drawings and specific embodiments. Before describing in detail the technical solutions of each embodiment of the present invention, the nouns and terms involved are explained. In this specification, components with the same name or the same number represent similar or identical structures and are only for illustrative purposes.
[0020] like Figure 1 and Figure 2 As shown, an immersion server fire extinguishing device includes a box body 1 in which a server 100 is installed, a coolant 2 for immersing the server 100 is arranged inside the box body 1, the server 100 may include one or more servers 100, and the server 100 may be arranged in the box body 1 according to certain rules, and also includes a fire detection tube 201, which is coiled on the inner top wall of the box body 1 and is located above the coolant 2; and a mounting member, which is installed on the top end of the box body 1 and fixes different sections of the coiled fire detection tube 201 to the box body 1, wherein the fire detection tube 201 is filled with a fire extinguishing medium, the fire detection tube 201 is located at the top end of the box body 1, and the fire detection tube 201 is constructed as a hose that softens and ruptures when heated. When a fire occurs inside the box body 1, the fire detection tube 201 ruptures The fire detection tube 201 can be used as a release port for the fire extinguishing medium, so that the fire extinguishing medium can quickly extinguish the fire inside the box 1. The fire detection tube 201 can be coiled in a variety of ways, such as serpentine coiling, U-shaped coiling or spiral coiling. In order to facilitate the removal and replacement of the fire detection tube 201, a serpentine coiling method is preferably adopted. The fire detection tube 201 is coiled in a serpentine manner, and the mounting part divides the fire detection tube 201 into several sections. The segmentation method can be selected by personnel in this field. After the fire detection tube 201 is segmented, the mounting part is installed on the top of the box 1 to fix the fire detection tube 201 and increase the fixing effect between different sections of the fire detection tube 201. When a single section of the fire detection tube 201 is sprayed, the impact on different sections is reduced as much as possible.
[0021] The mounting parts include a plurality of fixing cards 4 installed on the inner top wall of the box body 1, and the fixing cards 4 form an arc groove for clamping the fire detection tube 201 at one end facing the server 100, wherein both ends of each segment of the fire detection tube 201 are clamped on the top of the box body 1 by the fixing cards 4, and the fire detection tube 201 is clamped into the arc groove of the fixing cards 4, so that the installation method of the fire detection tube 201 is more stable, so as to reduce the jitter of the fire detection tube 201 caused by rupture.
[0022] The top surface of the box body 1 is installed with a panel 3, and the overlapping part of the fire detection tube 201 and the panel 3 is installed on the panel 3, wherein the panel 3 can be made of a transparent material, so that outsiders can observe the internal situation at any time. Part of the fire detection tube 201 is installed on the panel 3, so that when the middle part of the fire detection tube 201 is broken, its spraying is more stable, and it also prevents the fire detection tube 201 from falling at the panel 3. There are many ways to install the fire detection tube 201 and the panel 3, and the specific examples of its installation are as follows:
[0023] Embodiment 1:
[0024] like Figure 3As shown, a plurality of arc grooves are formed at one end of the panel 3 facing the server 100, and the arc grooves are clamped to the outer wall of the fire detection tube 201. The fire detection tube 201 is installed in such a way that one end passes through from one side of the panel 3 to the other side, so that the arc groove portion of the fire detection tube 201 at the panel 3 leaks out. When a fire occurs in the server 100 and the temperature rises, the arc groove portion of the fire detection tube 201 leaking out ruptures due to the heat, and the fire extinguishing medium is sprayed from the ruptured portion of the fire detection tube 201 toward the fire. Since the panel 3 fixes the middle part of the fire detection tube 201, the fire detection tube 201 will not shake back and forth, and the fire detection tube 201 is tightly pressed against the arc groove portion of the panel 3.
[0025] Embodiment 2:
[0026] The fire detection tube 201 runs through from one end of the panel 3 to the other side. A through hole is provided on the panel 3 and the side of the fire detection tube 201 facing the server 100. The contact portion between the panel 3 and the fire detection tube 201 is arranged in an arc shape. The number of holes can be set to be multiple. When a fire occurs in the server 100 and the temperature rises, the portion of the fire detection tube 201 located in the through hole ruptures due to the heat, and the fire extinguishing medium is sprayed toward the fire from the ruptured portion of the fire detection tube 201 corresponding to the position of the through hole. Since the panel 3 fixes the middle part of the fire detection tube 201, the fire detection tube 201 will not shake back and forth, thereby increasing the accuracy of the spraying.
[0027] On the basis of the above embodiment, the panel 3 is made of heat-insulating material to reduce heat loss, improve the sensitivity of the fire detection tube 201 to thermal rupture, and ensure that the rupture position of the fire detection tube 201 corresponds to the position of the arc groove or the through hole.
[0028] like Figure 1 and Figure 2 As shown, the inner top wall of the box body 1 is provided with a groove along the winding direction of the fire detection tube 201, and the part of the fire detection tube 201 away from the server 100 is located in the groove of the box body 1, wherein a groove for accommodating the fire detection tube 201 can be opened at the top of the box body 1, and can also extend at the top of the box body 1 toward the side wall of the fire detection tube 201, and at the same time, combined with the use of the fixing card 4, the three sides of the fire detection tube 201 are wrapped by the top wall of the box body 1, and only the leaking part of the fire detection tube 201 is sprayed toward the side wall of the server 100. With this arrangement, when the fire detection tube 201 is heated and ruptured, the fire detection tube 201 is restricted by the top of the box body 1, so that the position of the fire detection tube 201 during spraying is restricted, thereby further reducing the jitter of the fire detection tube 201 caused by spraying and improving the accuracy of spraying.
[0029] like Figure 1 and Figure 2As shown, a fire extinguishing element 200 is arranged outside the box 1, and the fire extinguishing element 200 is fixed to one end of the fire detecting tube 201 extending out of the box 1, and a fire extinguishing medium is contained in the fire extinguishing element 200, and the fire extinguishing medium can be perfluorohexanone, heptafluoropropane, etc. The valve of the fire extinguishing element 200 is opened to put the fire extinguishing element 200 in a working state, and the fire extinguishing medium can enter the fire detecting tube 201 by gas drive or other means.
[0030] The end of the fire detection tube 201 away from the fire extinguishing element 200 is equipped with a terminal head 202, which is installed on the side wall of the box 1, wherein the terminal head 202 can be a plug, a connection joint or a feedback device, and the terminal head 202 can be connected to the fire detection tube 201 by thread, flange or other connection methods to ensure sealing and reliability. For example: connected to the plug, so as to achieve fire extinguishing inside a single box 1; connected to the connection joint, so as to achieve series protection of multiple sets of boxes 1 and reduce fire protection costs; connected to the feedback device, it can have the functions of monitoring the storage pressure and spraying status of the fire extinguishing element 200.
[0031] Specifically, the feedback device can be used to detect whether the medium in the fire detection tube 201 is leaking. For example, when the fire extinguishing medium is not added to the fire detection tube 201 and no fire occurs in the box 1, the capacity of the fire extinguishing medium in the fire detection tube 201 should be fixed, which can be reflected in that the pressure in the fire detection tube 201 is within a certain range. When the pressure in the fire detection tube 201 drops, it can be determined that the fire extinguishing medium has leaked.
[0032] The above-described embodiments are merely descriptions of preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
