Solution Overview

Problem

Conventional computer cooling systems face inefficiencies in heat dissipation due to recirculation of hot air within closed computer casings, leading to overheating and poor performance, and water cooling block structures suffer from reduced heat exchange efficiency due to mixing of cold and hot fluids.

Innovation Solution

A computer cooling apparatus utilizing an evaporator, compressor, condenser, expansion valve, and fan, along with a coolant, is designed to efficiently dissipate heat by circulating the coolant through these components to absorb and dissipate heat from the central processing unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If a conventional heat sink with fan is used to dissipate heat, then the heat sink can absorb heat from the processor chip, but the hot air circulates within the closed computer casing resulting in poor heat dissipation

Engineering Contradiction:
Improveheat dissipation efficiencyVSAvoidhot air recirculation
Core Design Contradiction:
TemperatureVSObject-generated harmful factors

Solution Approach 1:

The patent extracts the heat dissipation process from the closed computer casing environment by using a refrigeration cycle system. The evaporator absorbs heat from the processor chip, and the compressor-condenser system discharges heat to the external environment, effectively removing hot air recirculation from the system and achieving efficient heat dissipation.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a refrigerant as an intermediary substance to transfer heat from the processor chip through the evaporator, compressor, and condenser. This intermediary enables heat to be moved from the internal closed space to the external environment, resolving the hot air recirculation problem.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Temperature

If a water cooling block structure is used to disperse heat source, then the working fluid can absorb heat from the processor chip, but the cold and hot fluids mix in the same containing space reducing heat exchange efficiency

Engineering Contradiction:
Improveheat absorption efficiencyVSAvoidheat exchange efficiency
Core Design Contradiction:
TemperatureVSProductivity

Solution Approach 1:

The patent segments the heat exchange process into distinct components: the evaporator for heat absorption, the compressor for pressure increase, and the condenser for heat discharge. This segmentation prevents mixing of cold and hot fluids by separating their paths, with the refrigerant flowing through dedicated channels in each component, thereby maintaining high heat exchange efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The refrigerant serves as an intermediary that undergoes phase changes to transfer heat efficiently. In the evaporator, it absorbs heat as a low-pressure liquid; in the condenser, it releases heat as a high-pressure gas. This intermediary mechanism avoids direct mixing of cold and hot fluids while maintaining effective heat exchange.

Inventive Principle:
Principle #24Intermediary (Mediator)
