Hot Isotropic Pressure Device Cooling Unit Gas Introduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hot isotropic pressure devices face challenges in efficiently cooling the treatment chamber after HIP treatment without narrowing the space, due to inadequate mixing of pressure medium gases and increased pressure differences requiring large motors.
Innovation Solution
The device incorporates a gas introducing unit with a conduit pipe and compulsory circulation unit to guide cooled pressure medium gas from the outside into the hot zone without intersecting the internal gas, ensuring efficient mixing and reducing the need for large circulation units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cooled pressure medium gas is introduced into the hot zone using existing circulation methods, then cooling efficiency is improved, but pressure difference increases requiring large motors
Solution Approach 1:
The patent introduces a gas introducing unit with a conduit pipe as an intermediary device to guide cooled pressure medium gas from the cooling unit directly into the hot zone. This intermediary structure enables efficient cooling by bypassing the need for large circulation motors, as the conduit pipe system utilizes pressure differential and gravity-assisted flow rather than high-power forced circulation.
2Speed
If large circulation units are used to improve cooling, then cooling speed increases, but treatment chamber space is reduced
Solution Approach 1:
The patent extracts the gas circulation function from large motor-driven units and implements it through a streamlined gas introducing unit with conduit pipes. This extraction allows the cooling system to achieve high cooling speed while occupying minimal space within the treatment chamber, as the conduit pipe system replaces bulky circulation equipment.
3Temperature
If pressure medium gas is circulated to cool the hot zone, then temperature is reduced, but gas mixing efficiency is insufficient
Solution Approach 1:
The patent segments the pressure medium gas circulation into distinct functional zones: a cooling unit for gas cooling and a gas introducing unit with conduit pipes for targeted delivery. This segmentation ensures efficient mixing by introducing cooled gas at specific locations within the hot zone through the conduit pipe system, creating effective temperature gradients and circulation patterns without requiring complex mixing mechanisms.
