Solution Overview

Problem

Existing evaporative cooling systems for air-cooled systems face issues such as pressure loss, corrosion, and high maintenance costs due to water evaporation and contamination, which reduce energy efficiency and require frequent filter replacements, especially when ambient temperatures exceed ISO design conditions.

Innovation Solution

A modular pre-cooling system with a rotating mesh mechanism, nozzles for controlled water spray, and a psychrometric analysis-based control unit that minimizes water usage, prevents water leakage, and uses a drift eliminator to manage pressure loss and contamination, while incorporating a dual-mesh structure for dust filtration and corrosion protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If direct evaporative cooling is applied using pads, then cooling efficiency is improved, but pressure loss increases and corrosion damage occurs

Engineering Contradiction:
Improvecooling efficiencyVSAvoidpressure loss and corrosion
Core Design Contradiction:
TemperatureVSObject-affected harmful factors

Solution Approach 1:

The system divides the evaporative cooling process into separate functional components: a drift eliminator section that prevents water particle detachment, a mesh structure that distributes water evenly, and a corrosion protection layer that isolates metal surfaces from corrosive environments. This segmentation allows each component to address specific issues independently while maintaining overall cooling efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary corrosion protection layer (such as protective coatings or sacrificial anodes) between the water/air environment and the metal components (condensers, serpentines, turbine blades). This intermediary prevents direct contact between corrosive elements and metal surfaces, eliminating the battery effect and sludge formation while allowing evaporative cooling to proceed uninterrupted.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If additional drift eliminator is added to eliminate water particle detachment, then corrosion protection is improved, but pressure loss increases and energy efficiency decreases

Engineering Contradiction:
Improvecorrosion protectionVSAvoidpressure loss and energy efficiency
Core Design Contradiction:
Object-affected harmful factorsVSUse of energy by moving object

Solution Approach 1:

The patent employs thin-film mesh structures and flexible water distribution layers that provide effective drift elimination and water distribution without creating significant flow resistance. These thin films allow air to pass through with minimal pressure drop while still capturing water particles and distributing cooling water evenly across the heat exchange surfaces.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The system optimizes the physical parameters of the drift eliminator and mesh structure (such as pore size, thickness, and material properties) to achieve the minimum necessary pressure loss. By carefully controlling these parameters, the system maintains effective corrosion protection while minimizing the impact on air flow and energy consumption.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If modular design is implemented for easy installation, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveinstallation and maintenance easeVSAvoidsystem structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system is divided into standardized modular units (drift eliminator sections, mesh assemblies, corrosion protection modules) that can be independently manufactured, installed, and maintained. Each module is designed with standardized connection interfaces, simplifying assembly and reducing installation complexity despite the overall system's functional sophistication.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular components are designed to perform multiple functions within a single integrated structure. For example, the mesh structure simultaneously serves as a water distribution medium, a drift elimination barrier, and a structural support element. This multi-functionality reduces the number of separate components needed, thereby reducing overall system complexity while maintaining ease of installation and maintenance.

Inventive Principle:
Principle #6Universality (Multi-functionality)
