Tunnel Series Platform Product Solution

We will use professional thermal analysis software to design the optimal scheme for customers, then confirm the
feasibility of the theory with engineers, and then start to make samples for testing

Input thermal resistance to select best TEM
TEA design output
Design target / Mechanical design / sampling & testing

Extrusion profile Design

Extrusion Fin Design
-The Fin Ratio ≤22:1
-The Fin Thick ≥0.7mm
- Fan Gap = 0.446(L²/ΔP) (unit: mm, Pa)
Extrusion profile Design output
