Abstract
A disclosed heater for a sealing process of a secondary battery includes: a sealing bar heating and pressing a pouch foil to be sealed; a plurality of sub-heating unit longitudinally disposed inside the sealing bar to respectively independently supply heat to a plurality of sections separated in the longitudinal direction of the sealing bar; temperature sensing units disposed inside the sealing bar and sensing temperature at positions on the surfaces being in contact with the pouch foil; and a control unit controlling heating temperature of the plurality of sub-heating units on the basis of the temperature sensed by the temperature sensing units.

A heater for a sealing process of a secondary battery, the heater comprising:
- a sealing bar heating and pressing a pouch foil to be sealed;
- a plurality of sub-heating units longitudinally disposed inside the sealing bar to respectively independently supply heat to a plurality of sections separated in the longitudinal direction of the sealing bar;
- temperature sensing units disposed inside the sealing bar and sensing temperature at positions on surfaces being in contact with the pouch foil;
- and
- a control unit controlling heating temperature of the plurality of sub-heating units on the basis of the temperature sensed by the temperature sensing units,
- wherein heat dissipation efficiency of the sealing bar decreases toward both longitudinal ends from a center portion thereof.
