Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid cooling systems in small intelligent terminals face issues with working medium loss leading to bubble formation, which affects pump operation, noise, and heat dissipation performance, and existing solutions like supplementation and exhaust apparatuses are too large for portable devices.
Innovation Solution
A gas collection apparatus with a temperature equalizing plate, pump, cooling plate, and pipeline, featuring a primary and secondary flow channel with connecting channels, designed to collect bubbles using increased local resistance without enlarging the apparatus size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If supplementation apparatus or exhaust apparatus are used to handle bubbles, then bubble collection capability is improved, but device size increases making it unsuitable for small terminal devices
Solution Approach 1:
The patent merges the bubble collection function with the existing cooling liquid circulation system by integrating a collection chamber into the cooling liquid channel. The cooling liquid pump, cooling liquid channel, and collection chamber form an integrated system where the cooling liquid circulation path also serves as the bubble collection path, eliminating the need for separate supplementation or exhaust apparatus.
Solution Approach 2:
The cooling liquid channel serves multiple functions: it cools the power component by circulating cooling liquid, and simultaneously acts as a bubble collection channel. The collection chamber is integrated into this channel, allowing the same circulation system to perform both heat dissipation and bubble collection functions.
2Temperature
If conventional liquid cooling apparatus is used, then heat dissipation performance is improved, but working medium loss occurs leading to bubble formation that affects pump operation and noise
Solution Approach 1:
The system uses the existing cooling liquid circulation to automatically collect and remove bubbles. The cooling liquid pump drives the cooling liquid through the collection chamber where bubbles accumulate, and the integrated design allows the system to self-regulate by continuously circulating cooling liquid that traps and removes bubbles without external intervention.
3Quantity of substance
If bubbles are present in the liquid cooling apparatus, then volume supplementation occurs, but pump operation is affected with excessive noise and reduced service life
Solution Approach 1:
The patent extracts bubbles from the cooling liquid circulation by providing a dedicated collection chamber where bubbles can accumulate and be removed. The collection chamber is positioned in the circulation path to capture bubbles that form during operation, separating them from the main cooling liquid flow to prevent them from entering the pump.
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
Effectively collects bubbles, reducing their return to the primary flow channel, maintaining pump operation, and enhancing heat dissipation performance without requiring external energy or increasing device size.
Implementation Method 1
bubbles carried when the working medium flows in the first flow channel
Implementation Method 2
local resistance to the working medium in the second flow channel is greater than local resistance to the working medium in the first flow channel
