Liquefaction promoting apparatus having vibrable and oscillable spring

Solution Overview

Problem

Current heat pump systems face inefficiencies in fluid liquefaction due to incomplete mixing of refrigerant and refrigerator oil, leading to energy wastage and reduced operating efficiency.

Innovation Solution

A liquefaction promoting apparatus is introduced, featuring a cylindrical housing with a large coil spring that vibrates and oscillates, and a small coil spring that also oscillates, designed to uniformly mix refrigerant and refrigerator oil within the heat pump system's pipeline, enhancing fluid mixing and liquefaction through kinetic energy and varying pitch configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a conventional stirring device with helical groove or coil spring is used, then fluid mixing is achieved, but the mixing effectiveness is insufficient leading to incomplete liquefaction

Engineering Contradiction:
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent employs a coil spring that vibrates and oscillates under the kinetic energy of flowing fluid to enhance mixing effectiveness. The vibration frequency and amplitude are controlled by the spring's physical parameters (diameter 1-10mm, pitch 10-50mm, length 50-200mm) to optimize liquefaction efficiency and reduce energy wastage.

Inventive Principle:
Principle #18Mechanical vibration

Solution Approach 2:

The invention transitions from static stirring structures to dynamic vibrating structures. The coil spring is designed to be unfixed at its middle part, allowing it to vibrate and oscillate freely in response to fluid flow, creating more effective mixing action compared to fixed helical grooves or springs.

Inventive Principle:
Principle #15Dynamics

2Productivity

If the coil spring is completely unfixed for maximum vibration, then mixing effectiveness improves, but structural stability and positioning control deteriorate

Engineering Contradiction:
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The coil spring is segmented into fixed ends and an unfixed middle part. This segmentation allows the spring to maintain structural stability at its ends while enabling vibration and oscillation in its middle section, resolving the contradiction between stability and mixing effectiveness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different parts of the coil spring have different degrees of freedom: the ends are fixed for stability, while the middle part is unfixed for vibration. This local differentiation of constraints optimizes both structural stability and mixing effectiveness simultaneously.

Inventive Principle:
Principle #3Local quality

AI summary

A fluid stirring and liquefaction promoting apparatus is coupled to a pipeline of a heat pump system to enable uniform mixture of refrigerator oil with refrigerant to improve the heat exchange efficiency of the heat pump system and to reduce the energy consumption. The liquefaction promoting apparatus is configured with a cylindrical housing, a system of tubes fluidly coupled between the pipeline and the interior of the cylindrical housing, as well as large and a small coil springs disposed in the cylindrical housing. Being actuated by the kinetic energy of the fluids circulating in the cylindrical housing, the large and small coil springs vibrate and oscillate to stir and mix the fluids to result in their uniform mixture.
