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 use method thereof. Background Art

[0002] The development of the concept of hot and cold separation in data centers stems from the high requirements 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 heat dissipation methods can no longer meet the needs. Secondly, environmental protection and energy saving have become the focus of global attention. As a large energy consumer, data centers need to adopt more environmentally friendly and energy-saving heat dissipation methods.

[0003] At present, data centers generally use closed cold channel technology. Cold air is sent into the closed cold channel through the air duct. 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 channel. Finally, the gas in the hot channel quickly returns to the return air outlet of the air conditioner. This method achieves complete isolation of hot and cold air and 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 temperature of the equipment.

[0004] However, in order to implement the closed cold channel 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. There are mainly the following problems:

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 ends of the combined outer tube bodies 61 are connected to the external environment. Two groups of exhaust interfaces 62 are provided. The two groups of exhaust interfaces 62 are respectively provided at the two top ends of the outer tube bodies 61. On the other hand, during the rotation and closing process of the electromagnetic locking door 3, the hot air guide duct 4 inside the electromagnetic locking door 3 rotates synchronously. After the hot air guide duct 4 rotates into place, the two sets of exhaust interfaces 62 are respectively fitted with the bottom of the hot air guide duct 4. The bottom of the hot air guide duct 4 is provided with an air outlet that cooperates with the exhaust interface 62. After the hot air guide duct 4 is fitted and connected with the exhaust interface 62, the hot air inside the hot air guide duct 4 enters into the exhaust interface 62 through the air outlet and converges to the inside of the outer exhaust pipe body 61 through the exhaust interface 62, and is finally discharged to the external environment by the outer exhaust pipe body 61.
