Solution Overview

Problem

Existing heat exchanger designs face challenges in achieving uniform distribution of fluids, particularly in block-in-tank configurations, where efficient gas-liquid separation and homogeneous distribution of refrigerants are desired.

Innovation Solution

A heat exchanger device with a distribution device comprising guide and distribution sections formed by perpendicular guide plates, where the distribution section has openings for fluid passage, ensuring fluid flows downward and is sealed laterally to prevent leakage, allowing for targeted distribution of fluids into specific regions of the jacket space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a simple inlet connection is used without distribution device, then device complexity is reduced, but fluid distribution uniformity deteriorates

Engineering Contradiction:
Improvedistribution device structureVSAvoidfluid distribution uniformity
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The distribution device is segmented into multiple functional components: a baffle plate with through-openings for flow distribution, a distribution plate with downward openings for directional control, and side plates for lateral sealing. This segmentation allows each component to perform its specific function optimally while collectively achieving uniform fluid distribution without excessive complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from simple planar flow distribution to three-dimensional directional control by adding vertical downward openings in the distribution plate. This dimensional addition enables fluid to be distributed not only horizontally across the jacket space but also vertically downward, creating more uniform multi-directional flow patterns

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If fluid inlet is placed locally in container wall, then device complexity is reduced, but fluid distribution uniformity deteriorates

Engineering Contradiction:
Improveinlet configurationVSAvoidfluid distribution uniformity
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The distribution device acts as an intermediary component between the local fluid inlet and the jacket space. The baffle plate and distribution plate collectively serve as a mediation system that receives fluid from a single inlet point and redistributes it uniformly across the entire jacket space, eliminating the direct connection between inlet location and flow distribution pattern

Inventive Principle:
Principle #24Intermediary (Mediator)

3Manufacturing precision

If lateral sealing is implemented with distribution device, then fluid distribution control is improved, but device complexity increases

Engineering Contradiction:

Solution Approach 1:

The side plates function as flexible sealing elements that can be configured in various geometries to achieve lateral sealing. These thin plate structures provide effective fluid containment and directional control without requiring complex multi-component sealing systems, maintaining manufacturing simplicity while achieving precise flow control

Inventive Principle:
Principle #30Flexible shells and thin films
