Solution Overview
Problem
Existing heat exchange systems in nanofabrication are unable to heat or cool formable materials to precise target temperatures (10° C. to 40° C.) and are difficult to clean, which affects the optimal jetting performance and efficiency of nanofabrication processes.
Innovation Solution
A heat exchange system with a housing, fins, and a sealing mechanism that allows for precise temperature control and easy cleaning, featuring a housing with supply and exit channels and transverse channels defined by fins, along with a sealing mechanism to form a hermetic seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a heat exchange system is designed to heat or cool formable material to precise target temperatures, then jetting performance is optimized, but the system becomes difficult to clean
Solution Approach 1:
The heat exchange system is divided into a removable cover portion and a base portion with separate cleaning access. The cover can be removed to expose internal channels and fins for cleaning, while maintaining the sealed heat exchange function when assembled. This segmentation allows cleaning access without compromising the temperature control precision achieved through the sealed heat exchange structure.
2Reliability
If the heat exchange system uses a hermetic seal to maintain temperature control, then temperature precision is improved, but cleaning access is restricted
Solution Approach 1:
The sealing mechanism transitions from a permanently sealed state to a dynamically accessible state. The cover can be removed to allow cleaning access to internal surfaces, then reattached to restore the hermetic seal for reliable temperature control. This dynamic design allows the system to switch between cleaning mode and operation mode, resolving the conflict between seal integrity and cleaning accessibility.
3Productivity
If the system maintains formable material at target viscosity through temperature control, then jetting performance is improved, but material switching and cleaning become more difficult
Solution Approach 1:
The removable cover design segments the heat exchange system into accessible and sealed portions. When material switching is required, the cover can be removed to facilitate thorough cleaning of internal surfaces that may have residual material. This segmentation enables complete cleaning access while maintaining the temperature control reliability needed for optimal jetting performance with the new material.

AI summary
A heat exchange system includes a housing, a cover, and a sealing mechanism. The housing includes an outer side, an inner side opposite the outer side, a supply channel on the inner side, an exit channel on the inner side, and a plurality of fins on the inner side. The plurality of fins define a plurality of transverse channels. Each transverse provides fluid communication between the supply channel and the exit channel. The cover covers the inner side of the housing. The sealing mechanism compresses the cover and the housing such that a seal is formed between the cover and the housing.
