Abstract
Description
Technical Field
[0001] This utility model belongs to the field of server room heat dissipation and fire safety technology, and relates to the heat dissipation and fire safety of arrayed server racks. In particular, it relates to an integrated heat pipe heat dissipation and point-type fire protection device to meet the synergistic needs of high-density data centers for energy efficiency and safety. Background Technology
[0002] In typical data center environments, numerous server racks operate under high loads for extended periods, generating significant heat. If this heat is not dissipated effectively and promptly, it can easily lead to overheating, impacting system stability and lifespan. Simultaneously, the concentrated arrangement of high-density electronic components and cables within the racks significantly increases the risk of electrical fires. Traditional cooling and fire suppression technologies are insufficient to meet the comprehensive needs of modern data centers, necessitating more efficient and reliable solutions.
[0003] As data centers evolve towards high density, modularity, and energy efficiency, traditional cooling and fire protection technologies struggle to simultaneously meet the dual demands of efficient heat dissipation and robust security. This is particularly true in rack layouts with in-row structures, where the spacing between racks is small and airflow channels are complex, making the coordinated design of fire protection and cooling systems crucial. However, current solutions often treat cooling and fire protection functions separately, failing to achieve their organic integration. For example, some standalone cooling optimization designs fail to adequately consider the space requirements and operational convenience of fire protection systems, resulting in low system integration and high design complexity. Traditional fire protection systems, on the other hand, neglect the impact on heat transfer between racks and rows, further increasing the difficulty of temperature control management in the data center. Therefore, achieving efficient, low-energy thermal management and precise, rapid fire response within limited space has become a core challenge in current server room design.
[0004] In summary, existing technologies for heat dissipation and fire protection systems in server racks suffer from problems such as low system energy efficiency, slow response speed, insufficient integration, and poor space adaptability. Therefore, designing an integrated solution that combines efficient heat dissipation, rapid and accurate fire response, and modular expansion capabilities has become a pressing technical challenge in the field of server room heat dissipation and fire safety.

In the first refrigeration loop formed by heat pipe heat exchanger I3-2, gas pipe I4-1, liquid pipe I5-1, and the outdoor cold source, the refrigerant absorbs heat from the server rack and evaporates into refrigerant gas. This gas then transfers heat to the outdoor cold source via gas pipe I4-1, cooling into refrigerant liquid. The refrigerant liquid flows back to heat pipe heat exchanger I3-2 via liquid pipe I5-1 and absorbs heat again to evaporate, thus discharging heat from the server room. The refrigerant flow direction in the first refrigeration loop is shown by arrow D in the diagram, and the air flow direction is shown by arrow E.
