Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of heat exhaust in server computer rooms, and relates to the heat management of server cabinets and the design and application of air-conditioning terminal equipment. In particular, it relates to a heat pipe air wall heat exhaust structure for server cabinets. Background Technique
[0002] As an important part of the computer room, the server cabinet undertakes a large amount of data processing tasks. At present, the heat flux density of server cabinets in computer rooms is getting higher and higher. Therefore, adopting an efficient heat dissipation system is the key to ensuring the normal operation of equipment and extending its service life. As a new type of air-conditioning terminal, heat pipe products have the characteristics of excellent heat conduction performance, high heat dissipation efficiency, and compact structure. They can replace the rear door of the server cabinet, or be installed between rows of cabinets, or be installed above the cabinet passage, directly cooling near the heat source, and have significant advantages in energy conservation.
[0003] Taking a cold wall type heat pipe backplane heat dissipation module disclosed in the Chinese utility model patent CN215453771U as an example, it is designed for high heat flux density cabinets. A modular closed channel is set between the cold wall type heat pipe backplane air conditioner and the exhaust air of a number of cabinets arranged in rows to form a certain installation and maintenance space. This design can not only maintain the servers in the cabinet online, but also effectively improve the heat dissipation efficiency. The cold wall type heat pipe backplane air conditioner adopts a modular design and is composed of a number of sets of modular heat pipe heat exchangers, a number of sets of fan modules and a controller, etc. When maintaining one set of modular heat pipe heat exchangers or fan modules online, the remaining modular heat pipe heat exchangers or fan modules solve the heat gathered in the modular closed channel, thus ensuring the stable operation of the system.
[0004] Although the cold wall type heat pipe backplane air conditioner has certain superiority in design, it is installed on the rear frame of the channel frame of the closed channel, which has certain load-bearing requirements for the closed channel. This means that during installation and maintenance, the channel frame needs to be strengthened, increasing the complexity and cost of the system. In addition, there are also certain limitations in the application flexibility of existing heat pipe heat dissipation technologies. For example, for some high heat flux density cabinets, although it is suitable to use heat pipe products for heat dissipation on the rear door side, the rear door side of the cabinet and the closed channel may not have the hanging conditions for heat pipe products. Therefore, more extensive and flexible application methods of heat pipe products need to be considered to adapt to different computer room environments and heat dissipation requirements.
[0005] In summary, although heat pipe technology has shown great potential in server cabinet heat dissipation, the existing technology still has problems such as installation condition restrictions and insufficient application flexibility. How to design a heat pipe heat dissipation structure that can not only meet the needs of high heat flux cabinets with efficient heat dissipation, online maintenance of servers, and redundant backup of cabinets in a row, but also adapt to different computer room environments and installation conditions, so that heat pipe products have a wider range of applications, is a technical problem that needs to be solved urgently.

[0012] The wind wall frame is a vertical frame as a whole, which is used to realize the overall support of the heat pipe wind wall module;
[0013] The plurality of fans are evenly installed in an array manner on a side of the wind wall frame away from the exhaust side of the row of cabinets to promote enhanced heat exchange between the heat pipe heat exchanger and the hot air flow in the closed hot channel;

The refrigerant liquid in the heat pipe heat exchanger thereof absorbs the exhaust heat of the in-line cabinets collected in the closed heat channel and then turns into refrigerant gas. The refrigerant gas enters the outdoor condensing unit through the gas pipeline, condenses into refrigerant liquid therein, and then returns to the heat pipe heat exchanger through the liquid pipeline to absorb heat and evaporate again, thereby discharging the heat of the servers in the in-line cabinets out of the computer room.
[0018] Preferably, the heat pipe wind wall module is floor-mounted and does not need to be hung on the closed heat channel frame. The overall micro-module structure is stable, there is no risk of deformation, and it is easy to maintain the servers in the in-line cabinets and the heat pipe wind wall module.
[0019] Preferably, the fan adopts a low-power adjustable-speed fan and is arranged in a uniformly distributed manner, which can realize the enhanced heat transfer of the heat pipe heat exchanger.
[0020] Preferably, a plurality of heat pipe wind wall modules arranged opposite to the in-line cabinets are provided, and a plurality of outdoor condensing units are adaptively provided. One or more heat pipe heat exchangers are provided in each heat pipe wind wall module, and wherein:

[0022] When the number of heat pipe heat exchangers provided in each heat pipe wind wall module is multiple, the heat pipe heat exchangers in the same heat pipe wind wall module are connected to different outdoor condensing units.
[0023] Preferably, a maintenance valve is installed on each of the liquid pipeline and the gas pipeline of each heat pipe heat exchanger to realize the on-off isolation between each heat pipe heat exchanger and the outdoor condensing unit.

Specifically, when the width of the heat pipe air wall module is equal to the width of the cabinet, each heat pipe air wall module can correspond to serving one cabinet; when the width of the heat pipe air wall module is twice or more integer multiples of the width of the cabinet, each heat pipe air wall module can correspond to serving multiple juxtaposed cabinets. Through this design, the size and quantity of the heat pipe air wall modules can be flexibly adjusted according to actual needs, and the space can be utilized more efficiently.
[0026] Preferably, a plurality of heat pipe air wall modules are provided to achieve mutual backup of the cooling capacity between the modules, ensuring that when one module fails or needs maintenance, other modules can continue to operate normally, thus guaranteeing the overall stability and reliability of the system.

The mesh door or the mesh guard plate can effectively prevent foreign objects from entering the heat dissipation system, while maintaining good air circulation to ensure that the heat dissipation effect is not affected. In addition, the mesh structure can also provide certain mechanical protection to prevent the fan or the heat pipe heat exchanger from being damaged by external forces, improving the durability and reliability of the overall system.

The refrigerant liquid in the heat pipe heat exchanger 1-2 includes the refrigerant liquid that absorbs the exhaust heat of the row of cabinets 2 collected in the closed heat channel 3 and then transforms into refrigerant gas. The refrigerant gas enters the outdoor condensing unit 5 through the gas pipeline 4 and condenses into refrigerant liquid, and then flows back to the heat pipe heat exchanger 1-2 through the liquid pipeline 6, absorbs heat and evaporates again, thereby discharging the heat of the row of cabinets 2 servers out of the computer room.
[0046] The heat pipe wind wall module 1 in the utility model is installed on the ground, and does not need to be hung on the closed heat channel 3 frame. The overall micro-module structure is stable, without the risk of deformation, and is easy to maintain the server in the cabinet 2 and the heat pipe wind wall module 1; the fans 1-3 preferably use low-power adjustable speed fans, which are evenly distributed, and can achieve enhanced heat exchange of the heat pipe heat exchanger 1-2.

When the number of heat pipe heat exchangers 1-2 set in each heat pipe wind wall module 1 is multiple, each heat pipe heat exchanger in the same heat pipe wind wall module is connected to a different outdoor condensing unit.
[0048] In some preferred embodiments, the liquid pipeline 6 and gas pipeline 4 entering and exiting each heat pipe heat exchanger 1-2 are equipped with a maintenance valve 7, which can realize the on-off isolation of each heat pipe heat exchanger 1-2 and the system pipeline; in addition, the heat pipe air wall module 1 can further include a controller 1-4 and supply and return air temperature sensors. The controller 1-4 is installed on the air wall frame 1-1, and the supply and return air temperature sensors are installed on the supply air side and return air side of the heat pipe heat exchanger 1-2 respectively. The controller 1-4 can control the speed of the fan 1-3 according to the temperature feedback from the supply and return air temperature sensors.
[0049] In some preferred embodiments, the width of the heat pipe wind wall module 1 is an integer multiple of the cabinet width, which is convenient for cabinet layout. Specifically, when the width of the heat pipe wind wall module is equal to the cabinet width, each heat pipe wind wall module can serve one cabinet; when the width of the heat pipe wind wall module is twice or a larger integer multiple of the cabinet width, each heat pipe wind wall module can serve multiple parallel cabinets.
[0050] In some preferred examples, the cold capacity can be backed up mutually among multiple heat pipe air wall modules 1, ensuring that when one module fails or needs maintenance, the other modules can continue to operate normally, thereby guaranteeing the overall stability and reliability of the system. In addition, such a width design makes it more flexible to expand or adjust the cabinet configuration, enabling it to quickly adapt to the requirements of computer rooms of different scales and densities, and improving the maintainability and expandability of the overall system.
[0051] In some preferred examples, an air filter can be optionally configured on the return air side of the heat pipe air wall module 1 to filter the dust and impurities in the return air after heat exchange through the heat pipe heat exchanger, thereby keeping the surface of the heat pipe heat exchanger clean and ensuring the heat exchange efficiency.

[0052] Embodiment 2
[0053] Figure 2 This is a schematic diagram of heat exchange between the heat pipe air wall module of the present utility model and the outdoor condensing unit when one heat pipe heat exchanger is adopted. When there is one heat pipe heat exchanger 1-2, the heat pipe air wall module 1 corresponding to the row of cabinets 2 can be connected to different outdoor condensing units at intervals. The odd-numbered heat pipe air wall modules 1 are connected to the outdoor condensing unit I 5-1 through the gas pipeline I 4-1 and the liquid pipeline I 6-1, where the refrigerant flow direction is as shown by the arrow A in the figure, and the cooling medium flow direction in the outdoor condensing unit I 5-1 is as shown by A1 in the figure; the even-numbered heat pipe air wall modules 1 are connected to the outdoor condensing unit II 5-2 through the gas pipeline II 4-2 and the liquid pipeline II 6-2, where the refrigerant flow direction is as shown by the arrow B in the figure, and the cooling medium flow direction in the outdoor condensing unit II 5-2 is as shown by B1 in the figure; the air flow directions in the row of cabinets 2, the enclosed hot channel 3, and the heat pipe air wall module 1 are as shown by the arrow E in the figure.

This design not only improves the flexibility and reliability of the overall heat dissipation system, but also ensures the normal operation of other modules during maintenance or in case of failure, thereby improving the stability and operation efficiency of the system. The air flow path in the row of cabinets and the enclosed hot channel further optimizes the heat dissipation effect of the computer room and ensures the stable operation of the server.
