Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heat dissipation methods for servers in data centers require larger cabinet sizes due to the integration of heat dissipation apparatuses, leading to increased costs and limitations on space utilization, and maintenance is cumbersome due to the need to detach these apparatuses for access.
Innovation Solution
A heat dissipation apparatus is positioned on the front or rear side of the cabinet, allowing for efficient liquid and air cooling of servers while utilizing space between adjacent rows, reducing cabinet size, and incorporating a liquid cooling unit with integrated distribution pipes and pumps for fault tolerance and energy efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heat dissipation apparatus is integrated into the cabinet, then heat dissipation requirement of server is met, but cabinet size increases
Solution Approach 1:
The heat dissipation apparatus is positioned on the front or rear side of the cabinet along the installation direction, utilizing the front-rear dimension rather than occupying left-right or up-down space inside the cabinet body. This dimensional repositioning allows effective heat dissipation while minimizing the cabinet's overall footprint.
Solution Approach 2:
The heat dissipation apparatus is extracted from the internal space of the cabinet and positioned on the external front or rear side. This separation removes the space-occupying conflict, allowing the cabinet to maintain a compact size while the heat dissipation function is performed externally.
2Temperature
If heat dissipation apparatus is integrated into the cabinet, then heat dissipation requirement of server is met, but maintenance complexity increases
Solution Approach 1:
The heat dissipation apparatus is extracted from the cabinet interior and positioned on the front or rear side, making it externally accessible. This allows maintenance personnel to access and maintain the apparatus without disassembling the cabinet or removing servers, significantly improving maintenance convenience.
Solution Approach 2:
The heat dissipation apparatus is designed as a separate, independent module positioned on the cabinet exterior. This segmentation allows the apparatus to be maintained independently without affecting the servers or requiring cabinet disassembly, simplifying the maintenance process.
3Temperature
If conventional heat dissipation method is used, then server heat dissipation is achieved, but cost increases
Solution Approach 1:
The heat dissipation apparatus is extracted from the cabinet interior and positioned on the front or rear side, eliminating the need for complex internal cooling systems and large cabinet spaces. This simplification reduces manufacturing costs while maintaining effective heat dissipation.
Solution Approach 2:
By positioning the heat dissipation apparatus on the front-rear dimension rather than occupying internal volume, the design achieves effective heat dissipation with minimal material and space requirements, reducing overall manufacturing costs.

Implementation Method 1
The liquid cooling unit is connected to a liquid cooling component on the server... heat generated by the first-type device is conducted to the interior of the liquid cooling component through a surface of the liquid cooling component, and then heat is conducted to the exterior of the first-type device by using liquid flowing in the liquid cooling component
Implementation Method 2
controlling the heat dissipation apparatus to start an air cooling mode, to perform air cooling on second-type devices on the servers

AI summary
The cabinet includes a body and a heat dissipation apparatus. A plurality of installation slots for servers to enter along a preset installation direction are disposed on the body. The heat dissipation apparatus is configured to perform heat dissipation on devices of the servers, the heat dissipation apparatus is disposed on at least one side of the body along the installation direction, and the heat dissipation apparatus is connected to the devices of the servers. In this way, heat dissipation is performed on each server in the body, and space reserved between two adjacent rows of cabinets can be effectively used to reduce occupation of space in a left-right direction or an up-down direction in the body, thereby reducing limitation on a size of the cabinet and a size of a device in the cabinet.
