Solution Overview

Problem

Existing gas flow control valves in heat engine air circuits experience limited cooling due to the lack of direct contact between the coolant and the valve, resulting in inefficient heat exchange and potential thermal stress on components.

Innovation Solution

An assembly comprising a gas flow control valve integrated with a receptacle that maximizes the cooling surface area around the cylindrical section of the valve body, allowing for direct contact between the cooling liquid and the valve components, thereby enhancing cooling efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If a cooling receptacle is used with external cooling conduits, then the valve can be cooled, but the heat exchange between coolant and valve is limited due to no direct contact

Engineering Contradiction:
Improvevalve temperatureVSAvoidcooling efficiency
Core Design Contradiction:
TemperatureVSReliability

Solution Approach 1:

The invention merges the cooling function directly into the valve body by integrating cooling channels within the valve structure itself, rather than using a separate external receptacle. This direct integration allows coolant to flow in close proximity to critical components, significantly improving heat exchange efficiency and cooling effectiveness.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cooling channels are nested within the valve body structure, with the coolant flow path embedded inside the valve housing. This nested arrangement allows the coolant to be in direct contact with or very close to the internal components, maximizing the cooling surface area and heat transfer efficiency while maintaining a compact design.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Temperature

If external cooling receptacle is used, then cooling can be provided, but the distance between coolant and internal elements is large limiting cooling quality

Engineering Contradiction:
Improveinternal elements temperatureVSAvoiddistance between coolant and valve elements
Core Design Contradiction:
TemperatureVSLength of stationary object

Solution Approach 1:

By combining the cooling system with the valve body into a single integrated structure, the invention eliminates the large distance between coolant and internal elements. The cooling channels are positioned within millimeters of critical components, enabling efficient heat removal from internal elements without requiring a separate external receptacle.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The invention relates to a gas flow control valve (10) designed to be attached to a container (32), the container having a cylindrical container body (34) and said valve comprising: - a valve body (12) that has a cylindrical section (14) which extends along a longitudinal axis (A) and is intended to be at least partially received in the container body when the valve is attached to the container, and - an open cavity (18) provided in said cylindrical section and extending across an angle range greater than or equal to 180° about the longitudinal axis of the cylindrical section, wherein said open cavity is designed to be closed by a wall of the container body to form a cover for said open cavity when the valve is attached to the container, thus forming a cooling duct (50) which is arranged and configured to convey a coolant liquid for cooling the valve when said valve is attached to the container.
