The study was done to decrease and to evenly disperse the heat transfer rate from the pouch-sealing unit to the cylinder part of the apparatus of manufacturing the battery for the electric vehicle. The pouch-sealing unit is made of the heating block having a cartridge heater, and the cylinder part is designed for moving the pouch-sealing unit. The heat transfer from the pouch-sealing unit to the cylinder deteriorate the performance of the cylinder working. The two different heat sinks made of aluminum fin, heat pipes, and the combination of heat sink and heat pipe were designed and tested for efficient cooling for the heating block. When the heat sink was applied to the system the temperatures of the heating block was lower by 21%, and for the combination of heat sink and heat pies the temperature decreased to 33%.
