Film-covered electrical device packaging system
View Patent ↗A film-covered electrical device packaging system of the present invention includes frame member ( 10 ) which holds film covered battery ( 1 ) by an outer periphery portion of film covered battery ( 1 ) and which has a portion thicker than the thickness of power generation element ( 2 ), and in which waste gas channel ( 10 i ) is formed in a position corresponding to gas discharger ( 8 ), and first pressure plate ( 20 ) which sandwiches frame member ( 10 ), in which penetrating portion ( 22 ) is formed in a position corresponding to waste gas channel ( 10 i ), and in which gas guide groove ( 21 ) communicating from through holes ( 22 ) to sidewall face ( 24 ) is formed.
1. A film-covered electrical device packaging system for fixedly holding a film-covered electrical device having an electrical device element, a case film which is arranged to surround said electrical device element, and a gas discharger provided in said case film, comprising:
a frame member which has a frame portion thicker than a thickness of said electrical device element, said frame portion holds an outer periphery portion of each film-covered electrical device in said frame portion, and in which a waste gas channel is formed in a position corresponding to said gas discharger; and
a pressure plate which holds down said frame member in a direction of the thickness of said frame member, in which a through hole is formed in a position corresponding to said waste gas channel, and in which a gas guide groove connecting from said through hole to a sidewall face is formed,
wherein said frame member has a space between said electrical device element and said pressure plate by a difference of said thicknesses between said frame portion and said electrical device element, and
wherein said frame member holds at least two film-covered electrical devices which are provided relative to each other in a direction which is perpendicular to the thickness direction.
2. The film-covered electrical device packaging system according to claim 1 , comprising a plurality of independent gas guide grooves.
3. The film-covered electrical device packaging system according to claim 1 , comprising said one gas guide groove having a plurality of said through holes.
4. The film-covered electrical device packaging system according to claim 1 , comprising said frame member that packages said film-covered electrical device, and a case that packages said pressure plate which holds down said frame member.
5. The film-covered electrical device packaging system according to claim 4 ,
wherein said pressure plate has a first fixing portion and a second fixing portion whose thickness is thinner than that of said first fixing portion,
wherein said pressure plate is fixed in said case by said first fixing portion abutting on a wall surface in said case, and
wherein a space is formed between said second fixing portion and said case.
6. The film-covered electrical device packaging system according to claim 4 ,
wherein said case has an opening portion which introduces cooling air, a check valve provided in said opening portion, and an exhaust port which discharges said cooling air, and
wherein said opening portion and said exhaust port are formed at positions such that the opening portion faces the exhaust port.
