Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology in computer rooms, and in particular to a waste heat circulation heating system for data centers. Background Technology

[0002] With the rapid development of information technology and the continuous expansion of data center scale, energy consumption issues are becoming increasingly prominent. When a large number of devices are running in the data center, about 90% of the electricity consumption is converted into low-temperature waste heat, which is currently mostly directly emitted, wasting energy and increasing the environmental burden. At the same time, many regions have high demand for heating in winter, and traditional centralized heating relies on fossil fuels, which are energy-intensive and have serious carbon emissions. Against this background, it is necessary to develop a waste heat circulation heating system for data centers, which is of great significance for improving the energy utilization rate of data centers and alleviating the pressure on heating energy.

[0003] In the waste heat circulation heating system of the data center, the plate heat exchanger is composed of corrugated metal plates and sealing gaskets. The plates are stacked to form hot and cold fluid channels. During operation, the high-temperature cooling water and the low-temperature heating return water in the data center flow in opposite directions on both sides of the channel. The heat exchange is completed through efficient heat conduction by the metal plates. The heated water is supplied to users, while the cooling water flows back to the data center to continue circulating.

[0004] Currently, most plate heat exchangers on the market have significant shortcomings in the application of waste heat circulation heating in data centers. During long-term operation, due to the dynamic changes in the heat generated by the equipment in the data center, traditional heat exchangers lack an effective adaptive compression mechanism. When the load fluctuation in the data center causes changes in the internal pressure and temperature of the heat exchanger, the plates are prone to problems such as sealing failure and leakage due to expansion or contraction. This not only reduces the heat exchange efficiency but also causes equipment failure. Therefore, a waste heat circulation heating system for data centers is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a waste heat circulation heating system for data centers, aiming to improve the problem of the lack of an effective adaptive compression mechanism in heat exchangers in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A waste heat circulation heating system for a data center includes a fixed frame. Multiple connecting pipes are fixedly connected to the front end of the fixed frame. Disassembly and assembly components are provided on the exterior of the multiple connecting pipes. Multiple thin metal plates are fixedly connected inside the fixed frame.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when the internal pressure or temperature of the heat exchanger changes and causes the plates to expand, the push plate is forced to push the sliding box to slide, and the spring is compressed to maintain a suitable clamping force to prevent leakage. When the pressure or temperature decreases, the spring extends to ensure the gap between the plates. In addition, the operator can change the position of the fixed box by rotating the threaded column and flexibly adjust the spring preload, which effectively protects the plates and improves the stability and service life of the equipment.

[0031] 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.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a data center waste heat circulation heating system, including a fixed frame 1. Multiple connecting pipes 4 are fixedly connected to the front end of the fixed frame 1. These connecting pipes 4 can connect to external pipes, allowing the cooling medium and circulating cooling water of the data center cooling system to smoothly enter and exit the fixed frame 1, providing a channel for subsequent heat exchange. The multiple connecting pipes 4 are arranged in a rectangular pattern at the front end of the fixed frame 1, which facilitates uniform fluid distribution and improves heat exchange efficiency. Disassembly and assembly components are provided on the outside of the multiple connecting pipes 4, enabling quick disassembly and installation of pipes during equipment cleaning and maintenance, improving work efficiency. Multiple thin metal plates 3 are fixedly connected inside the fixed frame 1. These thin metal plates 3 are key components for heat exchange, effectively increasing the heat exchange area and improving the heat exchange effect. Two guide rods 2 are fixedly connected to the outside of the fixed frame 1, guiding the sliding of other components and ensuring stability during sliding. A fixed plate 11 is fixedly connected to the outside of the two guide rods 2, and a telescopic column 15 is fixedly connected inside the fixed plate 11.

[0033] The telescopic column 15 can extend and retract within the fixed plate 11, and a spring 16 is fitted around its exterior. The spring 16 works in conjunction with the telescopic column 15 to provide elastic support for the components, adapting to different working conditions. A fixed box 13 is slidably connected to the exterior of the telescopic column 15, and the fixed box 13 can slide on the telescopic column 15. A sliding box 14 is also slidably connected to the exterior of the fixed box 13. This sliding connection between the sliding box 14 and the fixed box 13 allows for adjustment of the distance between components by sliding when the internal pressure of the heat exchanger changes, ensuring normal operation of the equipment. One end of the spring 16 is fixedly connected to the interior of the sliding box 14, and the other end is fixedly connected to the interior of the fixed box 13. The spring 16 acts as a support between the sliding box 14 and the fixed box 13. The elastic connection automatically adjusts the clamping force according to changes in internal pressure and temperature. The fixed plate 11 has a threaded post 17 inside, which can be rotated to adjust its position inside the fixed plate 11, thereby adjusting the position of the fixed box 13 and adjusting the preload of the spring 16. The front end of the sliding box 14 is fixedly connected to a push plate 12, which can move under the drive of the sliding box 14 to push the metal sheet 3. When the internal pressure of the heat exchanger changes, the push plate 12 can transmit the pressure to the metal sheet 3 to ensure the sealing effect between the plates. The push plate 12 is internally slidably connected to the outside of the guide rod 2, which guides the sliding of the push plate 12 and makes the push plate 12 more stable during the sliding process.

[0034] Reference Figure 1 and Figure 4The assembly and disassembly components include a threaded ring 7, whose inner wall is threaded to the outside of the connecting pipe 4. The threaded ring 7 can move on the connecting pipe 4 through the threaded connection, realizing the fixing and disassembly of the pipe. A retaining ring 8 is fixedly connected to the inner wall of the threaded ring 7. The retaining ring 8 and the inside of the connecting pipe 4 have a sliding groove 9. The retaining ring 8 can move with the threaded ring 7 to limit and fix the delivery pipe 5. The connecting pipe 4 has a sliding connection to the delivery pipe 5. The delivery pipe 5 is used to transport the cooling medium and circulating cooling water of the data center cooling system. It is an important channel for realizing waste heat circulation heating. Multiple sliding blocks 10 are fixedly connected to the outside of the delivery pipe 5. The sliding blocks 10 can slide in the sliding groove 9 inside the connecting pipe 4 to ensure the stability and sealing of the delivery pipe 5 inside the connecting pipe 4. A sealing ring 6 is fixedly connected inside the connecting pipe 4. The sealing ring 6 seals the gap between the delivery pipe 5 and the connecting pipe 4 to prevent fluid leakage and ensure the normal operation of the heat exchange process. The sliding groove 9 provides a sliding track for the sliding block 10, allowing the delivery pipe 5 to slide smoothly within the connecting pipe 4. The external sliding connection of the sliding block 10 is inside the sliding groove 9. The sliding of the sliding block 10 within the sliding groove 9 ensures the stability of the delivery pipe 5 and prevents it from shifting during operation. The rear end of the delivery pipe 5 contacts the front end of the sealing ring 6 to ensure a sealing effect and prevent fluid leakage from the connection between the delivery pipe 5 and the connecting pipe 4. The rear end of the retaining ring 8 contacts the front end of the sliding block 10 to limit the delivery pipe 5 and prevent it from sliding out of the connecting pipe 4. The external sliding connection of the delivery pipe 5 is inside the threaded ring 7, which can fix and seal the delivery pipe 5.

[0035] Working Principle: The cooling medium of the data center cooling system absorbs waste heat from the equipment in the data center and enters the interior of the fixed frame 1 through the conveying pipe 5 on the left side of the front end of the fixed frame 1, flowing through multiple metal plates 3. Simultaneously, circulating cooling water enters the fixed frame 1 and the interior of the multiple metal plates 3 through the conveying pipe 5 on the right side of the front end of the fixed frame 1, allowing the cooling water to absorb the temperature of the cooling medium. The cooled medium and heated cooling water are discharged from the conveying pipe 5 at the bottom of the front end of the fixed frame 1, achieving a circulation effect. The heated cooling water enters the heating circulation pipeline and is delivered to user terminals such as building heating equipment and domestic hot water systems, reusing the waste heat recovered from the data center for heating. When operators need to clean or maintain the heat exchanger, they can quickly disassemble the pipes and rotate the threaded ring 7 to loosen the threads. The ring 7 moves outside the connecting pipe 4, and the retaining ring 8 moves along with the threaded ring 7. When the retaining ring 8 connects with the sliding groove 9 inside the connecting pipe 4, the entire conveying pipe 5 can be quickly removed, completing the disassembly of the pipe for easy cleaning and maintenance. When installation is required, the conveying pipe 5 and the external sliding block 10 are slid into the connecting pipe 4 and the sliding groove 9, respectively. When the outside of the conveying pipe 5 is in contact with the outside of the sealing ring 6, the connection between the sliding groove 9 inside the retaining ring 8 and the sliding groove 9 inside the connecting pipe 4 is broken by rotating the threaded ring 7 in the opposite direction, thereby preventing the conveying pipe 5 from sliding out. At the same time, as the threaded ring 7 continues to rotate, the outside of the retaining ring 8 will squeeze the outside of the sliding block 10, restricting the position of the conveying pipe 5 while ensuring that the outside of the conveying pipe 5 is tightly in contact with the outside of the sealing ring 6, thereby achieving a sealing effect.

[0036] When the internal pressure of the exchanger increases or the temperature changes, causing the plates to expand, the push plate 12 will be squeezed, thereby pushing the sliding box 14 to slide outside the fixed box 13. The spring 16 will automatically compress to maintain a suitable clamping force and prevent the metal plate 3 from leaking. When the pressure decreases or the temperature drops, the spring 16 will automatically extend to maintain a certain gap between the metal plates 3, avoiding excessive clamping and damage to the plates. At the same time, the operator can change the position of the fixed box 13 by rotating the threaded column 17, thereby achieving the effect of adjusting the preload of the spring 16.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
