Solution Overview

Problem

Existing liquid-cooled load banks face issues with stagnant liquid retention, which can lead to microbial growth and corrosion, particularly when used in systems connected to sensitive electronics like GPUs, potentially damaging the cooling system.

Innovation Solution

A liquid-cooled load bank design with reservoir inlets and outlets positioned at the bottom, allowing complete draining and easy cleaning, combined with a control system for temperature and flow rate monitoring, and a pressure relief system to prevent damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If liquid-cooled load banks are used to test cooling systems, then cooling system performance can be verified, but stagnant liquid retention leads to microbial growth and corrosion

Engineering Contradiction:

Improvecooling system verificationVSAvoidmicrobial growth and corrosion

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent inverts the conventional inlet/outlet positioning by placing both the liquid inlet and outlet at the bottom of the heating reservoir instead of at the top. This inversion enables complete draining of the reservoir, preventing stagnant liquid retention and the associated microbial growth and corrosion problems while maintaining reliable cooling system testing capability

Inventive Principle:

Principle #13The other way round (Inversion)

2Power

If heating elements are added to create heating reservoir, then cooling capacity can be tested, but liquid stagnation occurs leading to corrosion

Engineering Contradiction:

Improveheating capacityVSAvoidcorrosion

Core Design Contradiction:

PowerVSObject-generated harmful factors

Solution Approach 1:

The patent positions the heating reservoir inlet and outlet at the bottom rather than the top, enabling complete drainage of the heating reservoir. This prevents liquid stagnation and corrosion while preserving the heating capacity needed for cooling system testing

Inventive Principle:

Principle #13The other way round (Inversion)

3Ease of operation

If reservoir openings are positioned at the top, then filling is easier, but complete draining cannot be achieved leading to microbial growth

Engineering Contradiction:

Improvereservoir fillingVSAvoidmicrobial growth

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent inverts the conventional opening positioning by placing both inlet and outlet openings at the bottom of the reservoir. This enables complete draining to prevent microbial growth while the design maintains operational ease through proper positioning and flow management

Inventive Principle:

Principle #13The other way round (Inversion)
