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 maintenance difficulties, while also limiting the space efficiency and convenience of server installations.
Innovation Solution
A heat dissipation apparatus is positioned on at least one side of the cabinet along the server installation direction, allowing for efficient liquid and air cooling, with integrated components like liquid cooling units, water pumps, and air-to-liquid units, and a control module to manage cooling modes based on power consumption and temperature, reducing space occupation and enhancing maintenance accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the heat dissipation apparatus is integrated inside the cabinet, then the heat dissipation function is provided, but the cabinet size increases and space efficiency decreases
Solution Approach 1:
The heat dissipation apparatus is extracted from the cabinet interior and positioned on the side of the cabinet along the server installation direction. This allows the cabinet to maintain its original size while still providing effective heat dissipation functionality through the externally positioned apparatus that contacts servers along their installation path.
2Temperature
If the heat dissipation apparatus is integrated inside the cabinet, then the heat dissipation function is provided, but maintenance convenience decreases
Solution Approach 1:
By extracting the heat dissipation apparatus from the cabinet interior and positioning it on the side, the apparatus becomes more accessible for maintenance operations. The side positioning allows maintenance personnel to access and service the heat dissipation apparatus without needing to disassemble cabinet structures or work in confined internal spaces.
3Volume of stationary object
If the cabinet size is reduced, then space efficiency increases, but the heat dissipation requirement of servers cannot be met
Solution Approach 1:
The heat dissipation function is moved from the internal three-dimensional space to the external surface dimension of the cabinet. By positioning the heat dissipation apparatus on the side of the cabinet along the server installation direction, the solution provides adequate heat dissipation capacity without increasing cabinet volume, effectively using the cabinet's external surface area for thermal management.
4Temperature
If conventional air cooling or liquid cooling methods are used inside the cabinet, then heat dissipation is achieved, but costs increase
Solution Approach 1:
The heat dissipation apparatus enables servers to dissipate heat during their own installation process. As servers are installed along the preset direction, they automatically contact the heat dissipation apparatus which provides cooling during and after installation, reducing the need for additional active cooling systems and associated energy costs.

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.
