Description

[0001] Cross-reference to related applications

[0002] This application claims the benefit of U.S. Provisional Patent Application No. 63 / 584,779, filed on September 22, 2023. Technical Field

[0004] This disclosure relates generally to heat exchangers, and more specifically to high-density heat exchangers, such as high-density heat exchangers for use with data centers. Background Technology

[0006] Data centers are experiencing ever-increasing heat density, demanding that thermal systems provide increased cooling density. Furthermore, the recent trend towards multi-tiered data centers requires higher heat dissipation per footprint. Additionally, emerging edge applications, such as containerized systems, also necessitate denser-packed cooling solutions. Both outdoor (heat dissipation) and indoor (cooling) heat exchanger coils can benefit from any improvements in density and footprint.

[0007] like Figure 1 As shown, a flat coil will provide a cooling area equal to its footprint. Figure 2 As shown, the "V"-shaped coil, an improvement on the flat coil, can have twice the cooling area of ​​its original footprint when the sub-coils or coil panels are at a 60-degree angle. Figure 3 As shown, the "V"-shaped coil can have a cooling area four times its footprint when the sub-coils or coil panels are at a 30-degree angle. For example... Figure 4 and Figure 5 The “V” shaped coil (A) shown in the figure V The cooling area of ​​the coil can be calculated using the following formula, where W is the coil width, H is the coil height, and α is the exterior angle of the coil relative to the horizontal plane:

[0008] Formula #1: A V = 2(W × H) / sin(α)

[0009] When viewed from the side, such as Figure 7 As shown, the "V"-shaped coil can use a triangular baffle to ensure airflow through the coil. Figure 8As shown, multiple "V" coils can be combined to increase the cooling area; however, this increases the system's footprint. Taller "V" coils can be used to increase the cooling area while maintaining the same footprint, but this increases the overall system size. Therefore, new topologies and methods are still needed to increase the density of heat exchangers for condensers, evaporators, and dry coolers, thereby helping to address this growing need for increased cooling density in various applications.
