Solution Overview

Problem

Existing modular counterflow cooling towers face challenges in efficient assembly, redundancy, and maintenance due to complex connections and lack of independent operation of heat transfer sections, which affect their reliability and efficiency in cooling hot process water.

Innovation Solution

A modular counterflow cooling tower design featuring pre-fabricated sections that can be quickly assembled, with independent operation of heat transfer sections, a central fan support for sealing, and a single hot process water inlet with manifold control, allowing for separate shipping and assembly of components, including integral water distribution systems within heat transfer sections or fan sections for efficient cooling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If modular sections are used for assembly, then assembly efficiency is improved, but connection complexity increases

Engineering Contradiction:
Improveassembly efficiencyVSAvoidconnection complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The cooling tower is divided into multiple independent modular sections (first heat transfer section, second heat transfer section, third heat transfer section) that can be manufactured separately and assembled on-site. Each module contains complete functional elements (fill media, water distribution system, collection system), enabling parallel transport and simplified assembly without complex inter-module connections.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If heat transfer sections are interconnected, then structural stability is improved, but maintenance redundancy is reduced

Engineering Contradiction:
Improvestructural stabilityVSAvoidmaintenance redundancy
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

Each heat transfer section operates as an independent module with separate water distribution systems and collection systems. The sections are positioned adjacent to each other but require minimal structural connection, allowing one section to be isolated for maintenance while others continue operating, thus maintaining both structural stability and operational redundancy.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A common water distribution manifold serves as an intermediary system that can supply water to multiple heat transfer sections independently. The manifold includes separate outlets and control valves for each section, enabling selective isolation and maintenance of individual sections without affecting the entire system's structural integrity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple water inlets are provided for each section, then water distribution flexibility is improved, but device complexity increases

Engineering Contradiction:
Improvewater distribution flexibilityVSAvoidinlet system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple heat transfer sections share a common water distribution manifold that consolidates the inlet system. The manifold includes a single main inlet that branches to multiple sections through controlled outlets, reducing the total number of external connections while maintaining flexible water distribution to each section through integrated valve systems.

Inventive Principle:
Principle #5Merging (Combining)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables efficient, flexible, and redundant cooling of hot process water with simplified assembly, reduced downtime during maintenance, and improved operational reliability by allowing independent operation of heat transfer sections and centralized fan support for effective air and water flow management.

Implementation Method 1

the fan draws air into the plenum of the cold water basin sections via air inlets provided on the external facing sides and/or ends of the cold water basin sections, up through the heat transfer media of the heat transfer sections, and out the top of the device

Methodology Applied
Scientific EffectForced Convection: Forced Convection

Implementation Method 2

Heated process water is delivered to the device via the single process water inlet and delivered to the water distribution systems located over the fill media where it is cooled in direct heat exchange with the air moving through the fill media

Methodology Applied
Scientific EffectHeat Exchange: Heat Exchanger

AI summary

A single inlet/single outlet modular counterflow cooling tower having two heat transfer sections installed atop two cold water basin sections and below three fan sections, each heat transfer section having its own water distribution system and draining into its own distinct cold water basin section. The water distribution system can provide flow over both heat transfer sections or over only a single section. The center fan support section supports the mechanical drive system for the fan and has a sealing plate at its bottom for sealing the gap between the two heat transfer sections.
