Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heat transferring devices are limited by the need for a specific orientation based on gravity, restricting their configuration and usability due to the downward movement of liquid working fluid and upward movement of gaseous fluid, which complicates design and increases costs.
Innovation Solution
A heat transferring device with a pumping structure that allows a gaseous working fluid to pressurize a liquid working fluid in a cooling part, enabling the liquid to move upward and be recovered downward without a separate power source, while incorporating a phase changing path and multiple heat dissipation structures to enhance heat transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional heat pipe is used where liquid working fluid moves downward and gaseous fluid moves upward based on gravity, then heat transfer function is achieved, but device configuration is limited and arrangement is complicated
Solution Approach 1:
The patent replaces the gravity-based mechanical movement system with a pressure-driven fluid circulation system. A pump actively circulates the working fluid through the heating section, phase change section, and cooling section, eliminating the need for gravity-dependent orientation and enabling flexible device configuration in various spatial arrangements.
Solution Approach 2:
The patent introduces dynamic pressure control through a pump system that actively regulates working fluid circulation. The pump can adjust flow rates and pressures to optimize heat transfer performance, allowing the system to adapt to different operational conditions and configurations rather than being fixed by gravitational constraints.
2Ease of operation
If a separate power source is added to enable liquid working fluid to move upward in cooling part, then fluid circulation is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The pump serves multiple functions: it drives working fluid circulation through the heating section, provides pressure for upward fluid movement in the cooling section, and enables flexible flow rate control. This multi-functional approach eliminates the need for separate power sources for different sections while improving overall circulation efficiency.
Solution Approach 2:
The patent merges the power source function into a single centralized pump system that handles all working fluid circulation requirements. This consolidation reduces device complexity by eliminating multiple separate motors or power sources, while still achieving improved fluid circulation through the entire heat transfer system.
3Reliability
If conventional heat pipe orientation is used with high temperature part at upper position and low temperature part at lower position, then gravity-based fluid movement works, but usability and application scenarios are limited
Solution Approach 1:
The patent replaces gravity-based fluid movement with pressure-driven circulation controlled by a pump. This substitution allows the heat transfer device to operate reliably in horizontal, vertical, or inclined configurations, expanding application scenarios to include heat exchangers, cooling systems, and thermal management devices in various orientations and locations.
4Productivity
If additional heat transferring part is added between cooling part and recovery part, then heat transfer amount increases, but device complexity increases
Solution Approach 1:
The additional heat transferring section utilizes the pressure-driven working fluid circulation to provide an extra heat exchange stage. The same pump-driven fluid flow that serves the primary heating and cooling sections also passes through this additional heat transfer section, maximizing heat recovery and transfer efficiency without requiring separate fluid circulation systems.

AI summary
A heat transferring device including a heater, a cooler, and a recoverer may be provided. The heater may be configured to heat a first liquid working fluid and change the first liquid working fluid to a gaseous working fluid. The cooler may be configured to cool the gaseous working fluid supplied from the heater and change the gaseous working fluid supplied from the heater to a second liquid working fluid. The recoverer may be configured to enable the second liquid working fluid from the cooler to move to the heater. Accordingly, the second liquid working fluid of the cooler may be movable in an upward direction and then recoverable using gravity, without a separate power source.
