Solution Overview
Problem
Conventional condensing apparatuses in two-phase liquid immersion cooling systems fail to condense all coolant vapor, leading to vapor accumulation and increased pressure, which compromises the reliability and cooling capacity of the system.
Innovation Solution
An openable and closeable condensing apparatus with two inclined condensing plates forms an enclosed space to completely condense rising coolant vapor, utilizing a fluid inlet and outlet manifold system with drainage modules to ensure all vapor is condensed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional condensing device is positioned above the coolant surface, then the device structure is simple and easy to install, but the coolant vapor scatters in all directions causing incomplete condensation and vapor accumulation
Solution Approach 1:
The patent transitions from a conventional horizontal condensing device to a vertical condensing apparatus. The condensing plates are arranged vertically above the coolant surface, forming a columnar structure that extends upward. This vertical arrangement allows the apparatus to intercept coolant vapor rising in vertical trajectories, preventing lateral scattering and ensuring complete condensation of all vapor phases within the enclosed space.
Solution Approach 2:
The condensing apparatus is divided into multiple independent condensing plates arranged in series vertically. Each condensing plate functions as a separate condensation unit with its own fluid passages and drainage modules. This segmentation allows the vapor to be condensed progressively as it rises through each plate, ensuring complete condensation while maintaining structural modularity and ease of installation.
2Reliability
If the condensing device is open-type, then the apparatus is easy to access for maintenance, but vapor can pass through without being condensed leading to pressure increase
Solution Approach 1:
The condensing plates are designed with movable connections between segments, allowing the vertical column to be dynamically assembled and disassembled. During normal operation, the plates are connected to form a closed vertical structure that prevents vapor escape. During maintenance, the connections can be easily separated to allow access to individual plates or components, thus maintaining both pressure control and ease of maintenance.
Solution Approach 2:
The drainage modules incorporate curved or inclined surfaces to facilitate smooth fluid flow from the condensing plates to the collection tank. The curved design prevents vapor entrapment and ensures complete drainage while maintaining a compact structure that can be easily accessed for maintenance.
3Reliability
If multiple condensing plates are arranged vertically, then complete condensation of all vapor is achieved, but the apparatus height increases requiring more space
Solution Approach 1:
The condensing plates are arranged in a nested or closely stacked configuration where each plate is positioned immediately above the previous one, minimizing vertical gaps. The drainage modules are integrated into the lower portions of each plate, allowing compact stacking. This nested arrangement achieves complete vapor condensation through multiple plates while minimizing the overall height and space requirements of the apparatus.

AI summary
The present invention discloses an openable and closeable condensing apparatus, which is particularly applied in a two-phase liquid immersion cooling system. When servers start to operate, a large amount of heat will be dissipated from servers. The coolant is vaporized into a rising coolant vapor by absorbing heat dissipated from servers. Upon contact with a condenser, the coolant vapor is condensed back into a cooling liquid that is returned to the coolant-containing tank. By the heat exchange cycle in which heat dissipated from serves is absorbed by the coolant, servers can be maintained at a normal working temperature. However, in the process of condensation, the rising coolant vapor tends to scatter in all directions resulting in a failure to condense all of the coolant vapor. Therefore, the uncondensed coolant vapor will cause the pressure in the system to gradually rise, which eventually leads to an ineffective cooling of servers. In view of this problem, the disclosed invention provides an enclosed-type condensing apparatus for completely condensing all of the coolant vapor.
