What material is ideal for EV battery pack thermal management? I think two-component thermal gap filler is preferred.
For instance, DOWSIL TC-4040, Bergquist Gap Filler TGF 3600 and GLPOLY XK-S40 are high performance thermal gap filling materials, they are suitable for today’s electrical vehicle battery pack thermal management system.
These three products provide similar functions, how do we select the right one for our applications and what’s the differences among them?
DOWSIL TC-4040 is a two part, dispensable thermal gel with 4.0W/mK thermal conductivity. it is printable or dispensable to cure as a sofft thermal pad for thermal transferring. It has good eletrical insulation, providing 2x1014Ωcm of volume resistivity.
Bergquist Gap Filler TGF 3600 is two part gap filling material with a thermal conductivity of 3.6W/mK, cured at room or elevated temperature. Prior to curing, the material maintains good thixotropic characteristics as well as low viscosity. Once cured, it remains a low modulus elastomer providing efficient heat transfer.
Compared with DOWSIL TC-4040 Dispansable Thermal Pad and Bergquist Gap Filler TGF 3600, GLPOLY XK-S40 is not so famous as the formers. What kind of material is GLPOLY XK-S40? Let’s check it out.
GLPOLY XK-S40 is a two part, thermally conductive, eletrical insulation dispensable thermal gel with 4.0W/mK of thermal conductivity, featuring high performance and superior softness. Low viscosity and gel-like material is designed to fill air gaps and voids yet flow when acted upon by an external force(e.g. dispensing or assembly process). GLPOLY XK-S40 Thermal Gap Filler is an excellent solution for interfacing fragile components with high topography or stack up tolerance to a universal heat sink or housing. GLPOLY Thermal Gap Filler XK-S40 is designed for electrical vehicle battery pack thermal transferring. It’s dispensable to cure as a thermal gel to replace thermal pad for stress relieving and shock dampening.
XK-S40 Thermal gap filler is suitable for robot system, the dose and dispensing paths are programmable and controllable. Comparing with thermal gap pad, acurate dispensing can be achieved, elimenating time consuming hand assembly, decreasing installation cost and logisticcal complexity. GLPOLY Thermal Gap Filler XK-S40 will lightly adhere to surface, thus improving thermal contact and reducing contact thermal resistance.
Generally, there is just a little differences among the three thermal gap fillers, each of them could be used for electrical vehicle battery pack thermal transferring, you can select any one you like. But if you select GLPOLY Thermal Gap Filler XK-S40, you will find it a high performance, cost-effective and a fast delivery solution.
GLPOLY thermal gap filler has been used in Lixing Auto in bulk production, it is highly reliable and stable.
