Integrated Injection Tube in Heat Exchanger Receiving Box
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing heat exchanger designs face challenges in simplified production and mechanical stability, particularly due to the complex integration of pressure reducers and insufficient mechanical stability of the receiving box.
Innovation Solution
The receiving box integrates an injection tube formed within the box body, allowing for simplified and cost-efficient production, enhanced mechanical stability, and efficient pressure reduction by shaping the box body to form the injection tube, which is fluidically connected to the ducts, enabling robust and compact construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If a separate injection tube is inserted into the receiving box as a pressure reducer, then pressure reduction functionality is achieved, but production complexity increases
Solution Approach 1:
The injection tube is merged with the receiving box by forming it as an integral part of the box body through shaping. This eliminates the need for separate injection tube components and simplifies production while maintaining the pressure reduction functionality.
Solution Approach 2:
The receiving box body is designed to serve multiple functions: it contains the duct system, provides structural support, and incorporates the injection tube functionality directly into its structure. This multi-functionality reduces the overall number of components and simplifies production.
2Stress or pressure
If a separate injection tube is inserted into the receiving box, then pressure reduction is achieved, but mechanical stability decreases
Solution Approach 1:
By merging the injection tube with the receiving box body into a single integrated structure, the mechanical stability is improved. The injection tube moves with the receiving box as a whole, eliminating relative movement and potential instability between separate components.
Solution Approach 2:
The injection tube is pre-formed as an integral part of the receiving box body during the shaping process. This preliminary formation ensures proper positioning and mechanical connection before the heat exchanger assembly is completed, enhancing overall structural stability.
3Ease of operation
If the receiving box is designed with separate components for duct and injection tube, then fluid flow functionality is achieved, but production cost increases
Solution Approach 1:
The receiving box body is shaped to integrate the duct and injection tube into a single component. This merging reduces the number of parts that need to be manufactured, assembled, and sealed, thereby reducing production costs while maintaining fluid flow functionality.
Solution Approach 2:
This principle is not applicable to the current patent as it relates to visual properties rather than structural or functional characteristics.

Function Achieved in This Case
This approach simplifies the production and enhances the mechanical stability of the receiving box, allowing for efficient pressure reduction and fluid flow, thereby improving the overall efficiency and robustness of the heat exchanger.
Implementation Method 1
The injection tube and/or the at least one outlet opening are advantageously designed in such a way, in particular dimensioned in such a way that a pressure reduction of the fluid and/or an expansion of the fluid occurs when the fluid flows through the at least one outlet opening into the duct.
