Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation equipment, and in particular to a data center heat exchange component based on a micro-cold pool and a method of using the component. Background Art

[0002] The development of the concept of heat and cooling separation in data centers stems from the high demands for energy efficiency and temperature management. With the rapid development of information technology, the computing density and heat density of communication rooms are constantly increasing. Traditional cooling methods can no longer meet the needs. In addition, environmental protection and energy conservation have become the focus of global attention. As data centers are large energy consumers, they need to adopt more environmentally friendly and energy-saving cooling methods.

[0003] Currently, data centers generally use closed cold aisle technology. Cold air is sent into the closed cold aisle through air ducts. The equipment at the front of the cabinet inhales the cold air. After the equipment completes heat exchange and cooling, the hot air is discharged from the back of the cabinet to the hot aisle. Finally, the air in the hot aisle is quickly returned to the air conditioning return vent. This method completely isolates the hot and cold air, avoids the mixing of hot and cold air, thereby improving the utilization rate of cold air, more effectively removing the heat generated by the equipment, and reducing the equipment temperature.

[0004] However, in order to implement closed cold aisle technology, the computer room needs to have certain layout conditions. For most existing computer rooms, large-scale renovation is required, which greatly increases the difficulty and cost of implementation. The main problems are as follows:

[0005] 1. The space in the computer room is insufficient. The closed cold aisle technology requires a certain height to accommodate the construction of aisle skylights and air conditioning ducts.

[0006] 2. Equipment cutover and relocation carries significant risks, creating significant uncertainty for the smooth and normal operation of equipment services and data security.

[0007] 3. The capital investment cost is high. The renovation of the computer room requires the construction of a new computer room that meets the layout and the construction of complete supporting measures, which is costly.

[0008] To this end, a data center heat exchange component based on a micro-cold pool and a method of use are proposed. Summary of the Invention

[0019] The method for using a data center heat exchange component based on a micro-cold pool includes the following steps:

[0020] Step S1: When multiple cabinets are arranged side by side, the cold air inlets provided on the cabinet doors are kept in a synchronous side-by-side arrangement, and two sets of adjacent extension frame bodies are connected through the connecting holes provided on their respective sides;

[0021] In step S2, the electromagnetic locking door is closed on the surface of the extension frame body by electromagnetic locking.

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments, wherein the above and other technical features and advantages of the present invention are further described. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive.

[0039] Example:

[0040] like Figure 1 - Figure 5As shown, the present invention provides a data center heat exchange component based on a micro-cold pool, including an extension frame body 1 arranged at the original cabinet door of the cabinet, with reset hinges 2 provided on both sides of the extension frame body 1. A set of electromagnetic locking doors 3 are installed on both sides of the extension frame body 1 through the reset hinges 2. The electromagnetic locking doors 3 are closed by electromagnetic adsorption. The reset hinges 2 drive the electromagnetic locking doors 3 to automatically open when the electromagnetic locking doors 3 are powered off. When a fire occurs, the reset hinges 2 drive the electromagnetic locking doors 3 to rotate and open when they are opened, so that the firefighting gas can quickly penetrate into the extension frame body 1 and the cabinet after being released, thereby better protecting the equipment in the cabinet.

[0041] A hot air guide pipe 4 is provided on the surface of the electromagnetic locking door 3, and a plurality of hot air delivery pipes 5 are provided inside the extension frame body 1. One end of the hot air delivery pipe 5 is connected to the exhaust port inside the cabinet, and the other end of the hot air delivery pipe 5 is connected to the hot air guide pipe 4. A hot air external exhaust pipe group 6 is provided at the bottom end of the extension frame body 1, and the bottom end of the hot air guide pipe 4 is connected to the hot air external exhaust pipe group 6.

[0042] The electromagnetic locking door 3 cooperates with the extension frame body 1 to form a sealed micro-cold pool inside the extension frame body 1. The hot air guide pipe 4, the hot air delivery pipe 5 and the hot air exhaust pipe group 6 cooperate to form a hot air channel. The hot air that completes the heat exchange is guided by the hot air delivery pipe 5 to the hot air guide pipe 4 and then to the hot air exhaust pipe group 6 by the hot air guide pipe 4. The hot air exhaust pipe group 6 finally discharges the hot air outward.

[0043] A cold air inlet 11 is provided at the top of the extension frame body 1, and the cold air inlet 11 is connected to an external cold air duct. When the cold air inlet 11 is in an open state, the cold air in the external cold air duct can be infused into the micro-cold pool inside the extension frame body 1 through the cold air inlet 11. The cold air stored in the micro-cold pool is used for heat exchange and heat dissipation of the equipment in the cabinet.

[0044] A connecting hole 12 is provided on the side of the extension frame body 1, and a closing plate 13 for closing the connecting hole 12 is installed on the surface of the connecting hole 12. When multiple cabinets are arranged side by side, the cold air inlets 11 arranged at the cabinet doors will maintain a synchronous side-by-side arrangement state. The two adjacent groups of extension frame bodies 1 are connected through the connecting holes 12 opened on their respective sides, that is, the micro-cold pools formed in the two adjacent extension frame bodies 1 are connected to each other, and the outer sides of the cold air inlets 11 located at the head and tail ends are closed by the closing plate 13 to form a common strip-shaped micro-cold pool.

[0045] A fixed slot 31 is provided on the surface of the electromagnetic locking door 3, and the hot air guide pipe 4 is installed inside the fixed slot 31. The hot air delivery pipe 5 is U-shaped to match the hot air delivery pipe 4. A through hole is provided on the surface of the hot air delivery pipe 4 to match the end of the hot air delivery pipe 5. The end of the hot air delivery pipe 5 extends into the hot air delivery pipe 4 through the through hole. The hot air delivery pipe 5 directly guides the hot air generated by the equipment in the cabinet into the inside of the hot air guide pipe 4, avoiding contact between the hot air and the cold air in the micro-cold pool, realizing the diversion of hot and cold air flows, and avoiding mixing of hot and cold air flows.

[0046] The hot air delivery pipe 5 includes a fixing bracket 51 and a delivery pipe body 52;

[0047] There are two groups of fixed brackets 51, and the two groups of fixed brackets 51 are respectively arranged on both sides of the inner wall of the extension frame body 1. The delivery pipe body 52 is clamped and fixed between the two groups of fixed brackets 51. With the assistance of the fixed brackets 51, the delivery pipe body 52 can be adjusted to a fixed position inside the extension frame body 1, so that one end of the delivery pipe body 52 can be better adapted and connected with the exhaust end of the equipment in the cabinet. During the rotation and closing process of the electromagnetic locking door 3, the hot air guide pipe 4 inside the electromagnetic locking door 3 rotates synchronously. After the hot air guide pipe 4 rotates into place, the other end of the delivery pipe body 52 is connected to the through hole on the surface of the hot air guide pipe 4. The hot air ejected from the exhaust end of the equipment in the cabinet is directly introduced into the hot air guide pipe 4 through the delivery pipe body 52. ​​The hot air entering the hot air guide pipe 4 enters the hot air exhaust pipe group 6 under the guidance of the hot air guide pipe 4.

[0048] The hot air exhaust pipe group 6 includes an exhaust pipe body 61, an exhaust port 62 and a connecting sleeve 63;

[0049] The outer tube body 61 is placed horizontally at the bottom end of the inner part of the extension frame body 1. When the extension frame bodies 1 are arranged side by side, the outer tube bodies 61 at the bottom of each group of the extension frame bodies 1 are connected to each other. When there is a gap between two adjacent groups of outer tube bodies 61, a connecting sleeve 63 is added between the outer tube bodies 61. The connecting sleeve 63 connects the two adjacent groups of outer tube bodies 61 to form a complete hot air flow channel. The end of the combined outer tube body 61 is connected to the external environment. There are two groups of exhaust interfaces 62, which are respectively arranged at the two top ends of the outer tube body 61. On the other hand, during the rotation and closing process of the electromagnetic locking door 3, the hot air guide tube 4 inside the electromagnetic locking door 3 rotates synchronously. After the hot air guide tube 4 rotates into place, the two sets of exhaust interfaces 62 are respectively fitted with the bottom of the hot air guide tube 4. The bottom of the hot air guide tube 4 is provided with an air outlet that cooperates with the exhaust interface 62. After the hot air guide tube 4 is fitted and connected with the exhaust interface 62, the hot air inside the hot air guide tube 4 enters the exhaust interface 62 through the air outlet and converges to the inside of the outer exhaust tube body 61 through the exhaust interface 62, and is finally discharged to the external environment by the outer exhaust tube body 61.

[0050] The method for using a data center heat exchange component based on a micro-cold pool includes the following steps:

[0051] Step S1: When multiple cabinets are arranged side by side, the cold air inlets 11 provided at the cabinet doors are kept in a synchronous side-by-side arrangement, and two sets of adjacent extension frame bodies 1 are connected through the connecting holes 12 provided on their respective sides;

[0052] In step S2, the electromagnetic locking door 3 is closed on the surface of the extension frame body 1 by electromagnetic locking. The electromagnetic locking door 3 cooperates with the extension frame body 1 to form a sealed micro-cold pool inside the extension frame body 1. At the same time, after the hot air guide pipe 4 rotates into place with the electromagnetic locking door 3, the other end of the delivery pipe body 52 in the hot air delivery pipe 5 is connected to the through hole on the surface of the hot air guide pipe 4, and the exhaust port 62 is respectively attached to the bottom of the hot air guide pipe 4.

[0053] Step S3: The micro-cold pools formed in the two adjacent extended frame bodies 1 are connected to each other, and the sealing plates 13 seal the cold air inlets 11 at the head and tail ends to form a common strip-shaped micro-cold pool;

[0054] Step S4: The cold air in the external cold air duct is fed into the micro-cold pool inside the extension frame body 1 through the cold air inlet 11. The cold air in the micro-cold pool is used for heat exchange and heat dissipation of the equipment in the cabinet.

[0055] Step S5: When the equipment in the cabinet is working, cold air in the micro-cooling pool is drawn into the equipment in the cabinet. The cold air completes heat exchange in the equipment in the cabinet and becomes hot air. The hot air is discharged from the exhaust port of the equipment in the cabinet.

[0056] Step S6: The hot air duct 5 guides the hot air generated by the equipment in the cabinet directly into the hot air guide duct 4 to prevent the hot air from coming into contact with the cold air in the micro-cold pool. The hot air entering the hot air guide duct 4 is guided by the hot air guide duct 4 into the hot air exhaust duct group 6.

[0057] In step S7 , the hot air inside the hot air guide pipe 4 enters the exhaust port 62 through the air port and converges to the inside of the outer exhaust pipe body 61 through the exhaust port 62 , and is finally uniformly discharged from the outer exhaust pipe body 61 .

[0058] The above description is merely a preferred embodiment of the present invention and is intended to be illustrative rather than restrictive of the present invention. Those skilled in the art will appreciate that many changes, modifications, and even equivalents may be made to the present invention within the spirit and scope of the claims, all of which fall within the scope of protection of the present invention.
