Integrated Receiver Dryer Layout for Easier Filter and Desiccant Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional receiver dryers for vehicle air conditioning systems are complex and require multiple components for refrigerant drying and filtering, making them difficult to manufacture and maintain.
Innovation Solution
A receiver dryer design with an elongate housing having separate sections for desiccant and filter, where the refrigerant flows through a conduit from the desiccant chamber to the filter chamber, allowing for easier replacement of components and integration with the condenser unit, reducing complexity and parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional receiver dryers incorporate multiple components (desiccant, filter, removable inserts, multiple conduits) to perform multiple functions, then the drying and filtering effectiveness is improved, but the device complexity increases and manufacturing becomes more difficult
Solution Approach 1:
The patent combines the desiccant chamber, filter chamber, and conduits into a single integrated receiver dryer housing. The internal wall creates separate chambers within one unit, eliminating the need for multiple separate components while maintaining all necessary functions for drying and filtering refrigerant
Solution Approach 2:
The single receiver dryer unit performs multiple functions: it dries refrigerant through the desiccant, filters refrigerant through the filter, and provides refrigerant storage. The integrated design makes one component that does the work of multiple separate components, reducing overall system complexity
2Reliability
If traditional receiver dryers have complex structures with multiple components, then functional requirements are met, but ease of manufacture deteriorates and production becomes more difficult
Solution Approach 1:
By merging the desiccant chamber, filter chamber, and conduits into one integrated housing with an internal wall partition, the design reduces the number of separate parts that need to be manufactured and assembled, thereby improving ease of manufacture while maintaining all necessary functions
3Reliability
If traditional receiver dryers have complex structures with multiple components, then functional requirements are met, but ease of repair deteriorates and maintenance becomes more difficult
Solution Approach 1:
The internal wall divides the housing into distinct desiccant chamber and filter chamber sections, allowing individual access and replacement of desiccant or filter elements without affecting the other components, thereby improving ease of repair and maintenance
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
The design simplifies the receiver dryer, reduces parts, and facilitates easy maintenance by allowing for separate replacement of desiccant and filter elements without draining the system, enhancing system efficiency and ease of use.
Implementation Method 1
The receiver dryer is also used to remove moisture from the refrigerant, and therefore, will typically include a chemical desiccant to remove water from the refrigerant
Implementation Method 2
The receiver dryer may further include a filter to remove any dirt from the liquid

AI summary
A receiver dryer for a motor vehicle air conditioning system includes an elongate housing, the housing having opposite ends and an external wall that extends between the ends, an inlet positioned in a first section of the housing for receiving condensed refrigerant from the condenser unit, an outlet positioned in a second section of the housing for providing dried condensed refrigerant to the condenser unit with a partition dividing the first section from the second section such that the second section is above the first section, a first chamber in the first section containing a desiccant for drying the refrigerant received from the inlet, a second chamber in the second section containing a filter for filtering the dried condensed refrigerant provided to the outlet, and a conduit.
