Provided is a battery temperature control unit which can ensure water tightness which a sealing member of a module case or the like is required to possess and gas tightness of a refrigerant and, at the same time, can simplify assembling steps. A battery temperature control unit 1 is a battery temperature control unit for controlling a temperature of an internal space 21 of a module case 22. The battery temperature control unit 1 includes: a unit case 3 which is arranged in the internal space of the module case 22 and includes an air flow passage 4 in the inside thereof; and a heat exchanger 11 arranged in the air flow passage 4. The unit case 3 includes a module opening sealing portion 31 which seals a module opening 24 formed in a wall surface of the module case 22. In the module opening sealing portion 31, a module sealing surface 32 which closes the module opening 24 from an internal space 21 side, and a first communication hole 36 and a second communication hole 37 which allow the outside of the module case 22 and the inside of the unit case 3 to communicate with each other are formed. |
