Structural heat sink bonding of battery cells Battery cells for low-voltage systems are often mechanically connected to a housing or a heat sink, requiring additional gap fillers or thermal pads for heat dissipation. DELO’s structural TCAs (thermally conductive adhesives) allow for battery cells to be bonded into the housing while simultaneously connecting them to the thermal management system, efficiently dissipating heat. This simplifies the production process, eliminating the need for gap fillers or thermal pads. Assembly process ` Structural bonding of battery cells to housing `...
