The vape tank contains a heating element, usually a coil made of a resistance wire such as kanthal, which is heated by the battery. The e-liquid, containing propylene glycol and vegetable glycerin, is drawn into the coil and heated to a high temperature, creating vapor.
The wicking material, typically cotton or silica, is responsible for absorbing the e-liquid and delivering it to the heating coil. It must be able to withstand high temperatures and have good absorption properties to ensure proper vapor production.
The airflow control on a vape tank allows the user to adjust the amount of air that is allowed into the tank. This can affect the temperature and density of the vapor produced. More airflow can result in cooler vapor, while less airflow can result in warmer, denser vapor.
The chimney is the tube that connects the tank to the mouthpiece. Its main purpose is to channel the vapor created by the heating coil to the mouthpiece for inhalation. It also helps to prevent any leaking of e-liquid from the tank.
Sub-ohm vaping, where the coil has a resistance of less than 1 ohm, allows for higher wattage and temperature settings, resulting in a larger amount of vapor production. This is due to the increased surface area of the coil, which allows for more efficient heating of the e-liquid. Traditional vaping with a higher resistance coil produces less vapor but can provide a stronger throat hit due to the higher concentration of nicotine in the vapor.
