Provided is a secondary battery module which is improved in the temperature control efficiency of unit battery by modifying the circulation structure of cooling medium and is minimized in the temperature deviation of unit batteries. The secondary battery module(10) comprises at least one battery assembly(11) which comprises a layered unit batteries(12); a housing(20) which accommodates the battery assembly and circulates the cooling medium for the control of temperature; and an inducing member(30) which is installed on the propagation passage(23,24) of the cooling medium formed along the housing and is toward the inlet(21) of cooling medium at the end part of the passage. Preferably the front end toward the inlet of cooling medium of the inducing member has a wedge form. |
