Solution Overview

Problem

Existing cooling towers require a large height dimension, which limits their placement, transportability, and increases energy consumption due to the need for vertical pumping of hot water, and they cannot be efficiently stacked or positioned closely together.

Innovation Solution

A cooling tower design with a skeletal frame conforming to ISO container dimensions, featuring telescoping legs, reduced vertical spacing, and a low-pressure water distribution system with increased nozzle density, allowing for compact stacking and efficient air flow, thereby reducing the need for vertical pumping and lowering energy costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional cooling tower design is used with sufficient standoff distance for water distribution, then proper water distribution is achieved, but the height dimension becomes excessively large

Engineering Contradiction:
Improvewater distributionVSAvoidheight dimension
Core Design Contradiction:
Ease of manufactureVSLength of stationary object

Solution Approach 1:

The patent repositions the water distribution system from above the fill media to the sides of the cooling tower body, changing the spatial arrangement from vertical to lateral distribution. This dimensional change eliminates the need for large vertical standoff distance while maintaining effective water distribution across the fill media surface.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent employs adjustable telescoping support legs that can be extended or retracted to optimize the positioning of the water distribution system relative to the fill media. This dynamic adjustment capability allows proper water distribution without requiring fixed large vertical clearance.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If large height dimension is used for vertical spacing, then water distribution and air flow are adequate, but transportability and stacking capability are reduced

Engineering Contradiction:
Improvewater distribution and air flowVSAvoidtransportability and stacking
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The telescoping support legs can be retracted to minimize the overall height of the cooling tower for transport and stacking operations, while being extendable to provide adequate vertical spacing for water distribution and air flow during operation. This dynamic dimension adjustment resolves the contradiction between operational requirements and transportability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The cooling tower is designed as a modular unit with separable components including the skeletal frame, fill media, and support legs. This segmentation allows the tower to be disassembled or compacted for transport while maintaining full functionality when assembled, enhancing both transportability and operational performance.

Inventive Principle:
Principle #1Segmentation

3Ease of manufacture

If large height dimension is used, then proper water distribution spacing is achieved, but energy consumption increases due to vertical pumping

Engineering Contradiction:
Improvewater distribution spacingVSAvoidvertical pumping energy
Core Design Contradiction:
Ease of manufactureVSUse of energy by moving object

Solution Approach 1:

By transitioning from vertical water distribution (top-down spray) to lateral water distribution (side-mounted nozzles), the patent eliminates the need for pumping water to great heights. The lateral distribution system delivers water directly to the fill media at minimal elevation change, dramatically reducing the energy required for vertical pumping while maintaining adequate distribution spacing.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Temperature

If traditional spacing is used, then cooling efficiency is maintained, but the cooling towers cannot be positioned closely together or stacked

Engineering Contradiction:
Improvecooling efficiencyVSAvoidspacing between towers
Core Design Contradiction:
TemperatureVSArea of stationary object

Solution Approach 1:

The lateral water distribution system allows cooling towers to be positioned much closer horizontally since water is distributed from the sides rather than requiring large vertical clearance. This enables tighter packing of multiple towers in parallel arrangements while maintaining effective water distribution and cooling efficiency through the side-mounted nozzle system.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A cooling tower for evaporative cooling of water is contained within an ISO-compliant shipping container frame, permitting stacking of cooling towers for transport and for certain industrial applications. A volume of fill media is contained within the frame. Spaced apart troughs underlie the fill media, running substantially the length of the fill media and connecting to a basin. Baffles are connected to one upper edge of the troughs, while an air flow space is positioned over the other upper trough edge. A water distribution system, with variable flow nozzles positioned closely above the fill media, sprays water over the upper surface of the fill media, where it moves by gravity down into the troughs. Fans atop the fill media move air vertically upward through the fill media.
