Claims21
A battery pack that houses a secondary battery inside a case, comprising:
- an exhaust part, by means of which an internal space of the case where the secondary battery is housed is in communication with outside, and which allows a gas discharged from the secondary battery to be discharged from the internal space to the outside;
- and
- a heat exchanger, which is provided at the exhaust part and formed of a porous material having a three-dimensional mesh structure, and through which the gas passes,
- wherein
- assuming that a predetermined direction is a first direction, the heat exchanger comprises a high-density portion having a size in the first direction that is smaller than that of a remaining portion and having a density higher than that of the remaining portion, and
- the high-density portion is fixed to the case.
A battery pack that houses a secondary battery inside a case, comprising:
- an exhaust part, by means of which an internal space of the case where the secondary battery is housed is in communication with outside, and which allows a gas discharged from the secondary battery to be discharged from the internal space to the outside;
- and
- a heat exchanger, which is provided at the exhaust part and formed of a porous material having a three-dimensional mesh structure, and through which the gas passes,
- wherein
- the heat exchanger comprises a shielding portion that blocks pores located at an inner surface of the porous material facing the internal space.
