Engine Coolant Bubble Outlet Unit for Heat Pump Compressor Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heat pump systems face inefficiencies due to bubbles in the coolant, which reduce cooling effectiveness and make it difficult to maintain consistent engine temperature, leading to potential engine damage and increased service time.
Innovation Solution
A heat pump system with a bubble outlet unit connected between the exhaust gas heat exchanger and heat radiator, featuring separate coolant inlet and outlet lines and a bubble outlet hole, effectively removes bubbles from the coolant by utilizing a coolant pump and water level sensors to manage coolant flow and bubble discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a coolant circulation channel is provided to cool the engine, then the engine cooling effect is improved, but bubbles are drawn into the channel causing cooling effect deterioration
Solution Approach 1:
The patent extracts and removes bubbles from the coolant by providing a dedicated bubble outlet hole in the coolant supply line, separating the harmful bubbles from the cooling system while allowing clean coolant to continue circulating through the engine
2Productivity
If bubbles are contained in the coolant, then the coolant circulation continues, but the cooling effect and heat recovery amount are reduced
Solution Approach 1:
The patent converts the harmful effect of bubbles into a beneficial separation process by using the bubble outlet hole to actively remove bubbles, thereby transforming the presence of bubbles from a detrimental factor into an opportunity for improved heat recovery and cooling efficiency
3Duration of action of moving object
If bubbles are present in the coolant, then circulation continues, but temperature control consistency deteriorates causing engine hunting
Solution Approach 1:
The patent extracts bubbles that cause temperature fluctuations from the coolant stream through the bubble outlet hole, ensuring consistent temperature control and preventing engine hunting while maintaining continuous coolant circulation
