Perpendicular Protrusion Forming for Heat Exchanger Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for forming protrusion parts, such as heat radiation fins, that are rolled back result in poor air exchange and reduced cooling capacity due to the difficulty in exchanging air between the fins and outer air.
Innovation Solution
A protrusion forming device with a holding portion, tool bit, and drive portion that cuts a protrusion part perpendicular to the object's outer surface, using a cutting tool bit to create linear or perpendicular protrusions connected to the object, enhancing heat transfer efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the protrusion part is shaped to be rolled back to increase cutting efficiency, then the cutting efficiency is improved, but the air exchange between the radiation fins and outer air becomes difficult, reducing cooling capacity
Solution Approach 1:
Instead of rolling back the protrusion part as in conventional methods, this invention inverts the approach by forming the protrusion part to extend perpendicular to the outer surface through a three-stage cutting process (cut-in pathway, further-cut pathway, and forming pathway), thereby improving air exchange and cooling capacity while maintaining manufacturing efficiency
2Reliability
If the protrusion part is formed extending perpendicular to the outer surface, then the cooling capacity is improved, but the cutting process becomes more complex
Solution Approach 1:
The cutting process is segmented into three distinct pathways: (1) cut-in pathway to insert the cutting portion into the object, (2) further-cut pathway to create a linear protrusion, and (3) forming pathway to shape the protrusion perpendicular to the surface. This segmentation simplifies the overall process by breaking down the complex perpendicular formation into manageable sequential steps
3Ease of manufacture
If the protrusion part is formed by conventional rolling back method, then the manufacturing process is simple, but the heat transfer efficiency is reduced
Solution Approach 1:
The invention replaces the conventional mechanical rolling back method with a precision cutting system that uses a tool bit with a cutting portion to directly form the perpendicular protrusion. This substitution of the forming mechanism enables better heat transfer efficiency while maintaining manufacturing feasibility through automated multi-pathway cutting

AI summary
A protrusion forming device includes a holding portion holding an object that is be processed, a tool bit having a cutting portion capable of cutting an object held by a holding portion, and a drive portion capable of driving the tool bit. The tool bit is movable along a cut-in pathway so that the cutting portion is inserted into the object. The cutting portion is movable along a further-cut pathway so as to form a protrusion part that is cut in a linear shape and is connected to the object. The tool bit continuously contacts the protrusion part while moving along a forming pathway such that the protrusion part extends perpendicular to an outer surface of the object.
