A thin coating of Thermal Interface Material (TIM), also known as a gap filler, helps the heat transfer from a battery to the cooling plate by creating an effective thermal pathway between the battery pack and the cooling plate.
To fill up the tiny spaces between hot components and a chassis or heat sink assembly, thermal gap fillers are created in laboratories and inserted into electronic devices and systems. Due to the low thermal conductivity of air, these spaces act as thermal barriers to heat transport.
The small air spaces between components and casings are filled using thermal gap fillers. They fill the area so that a heat-generating component can have the best possible heat resistance. This enables the component and device as a whole to perform at their highest potential. Thermal interface materials (TIMs) known as gap fillers transfer heat away from delicate components in electronic assemblies.
They typically consist of a ceramic filler and silicone rubber. Gap fillers, like other TIM kinds, are intended to fill the minute air spaces between a heat source and a heat sink. A combination of forced air cooling, liquid cooling, and thermoelectric cooling is used in the newly developed battery thermal management system. In order to remove the heat produced by the battery during operation, the liquid coolant makes indirect contact with the battery.
The most popular filler substances are talc, kaolin, precipitated calcium carbonate (PCC), carbon black, and ground calcium carbonate (GCC). Tensile strength, toughness, heat resistance, colour, clarity, and other properties can be impacted by filler components. Talc added to polypropylene is a prime illustration of this.
The global EV thermal gap filler market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
At Productronica, Electrolube will introduce a New Generation of Conformal Coatings & Thermal Gap Fillers. At this year’s Productronica, the international electro-chemicals producer Electrolube, a division of MacDermid Alpha Electronics Solutions, will present its most intriguing conformal coating and thermal management advancements ever (Messe Munich.
A highly thermally conductive thermal gap filler suitable for a variety of applications, such as EVs, batteries, and chargers, to name a few, as well as a game-changing new two-part, bio-based conformal coating that is completely unique to the industry, will be the protective solutions taking centre stage at the show. The newest technologies from Electrolube will be on display at the Macdermid Alpha booth 466 in Hall A4.
Future coatings across the industry are expected to change thanks to one of the company’s most innovative products. Electrolube, a recent MacDermid Alpha Electronics Solutions acquisition, has once again embraced market trends and created a first-to-market conformal coating with remarkable qualities that can be used wherever a coating is required and is perfect for automotive and EV applications.
The adaptable new coating from Electrolube will be covered in more detail before to debut. Automotive electronic assemblies are vulnerable to high levels of mechanical shock and vibration, as well as chemical attack from fuels, lubricants, and salt mist environments.
nElectrolube has decades of experience preserving these systems. The important automotive control and safety-related components are continuously operational thanks to Electrolube’s high level protection solutions.
