Liquid-cooled assembly of disc cells

Claim 2

A disc cell assembly comprising a stack of members including at least one disc cell having a coolant member coordinated therewith and at least one insulating member, and a force-storing member clamping the members of said stack between two opposing bearings of a framework, said coolant member comprising a cooling pan having a hollow inner space, a channel member having means for supplying thereto and discharging therefrom a liquid coolant, said channel member being located adjacent said cooling pan so as to close off the inner space of said cooling pan, and sealing means disposed intermediate said cooling pan and said channel member, said force-storing device having such a biasing force as to form a liquidtight force fit between said cooling pan and said channel member.

Claim 3

Assembly according to claim 1, wherein said coolant pan has a base and a lateral wall, and a distributor member formed with a central bore is seated in said inner space of said cooling pan for guiding a flow of coolant from said channel member through said central bore against said base of said coolant pan and between said lateral wall of said coolant pan and said distributor member back into said channel member.

Claim 4

Assembly according to claim 2, wherEin said cooling pan is formed with a flange having a surface on which said channel member is supported, said flange being formed with an annular groove in said surface thereof for receiving a seal therein, said distributor member having a surface disposed in the same plane as said surface of said flange.

Claim 5

Assembly according to claim 2, wherein said channel member comprises a plate having opposite flat sides extending substantially parallel to one another, said plate being formed with two transverse bores extending through said plate substantially, perpendicularly to said flat sides thereof, and including centering means located on both sides of said channel member and on one side of said cooling pan for mutually aligning said channel member and said cooling pan so that one of the transverse bores formed in said channel member communicates with the central bore of said distributor member, the other transverse bore formed in said channel member being in communication said inner space of said cooling pan between said lateral wall of said coolant pan and said distributor member, said channel member having a pair of narrow sides located at one end thereof, and including a longitudinal bore formed in said plate and extending parallel to said flat sides thereof from each transverse bore, respectively, through a respective narrow side to the outside of said plate.

Claim 6

Assembly according to claim 4, wherein said longitudinal bores have axes defining an acute angle therebetween, said narrow sides in the vicinity of the outlet of said longitudinal bores from said plate extending parallel thereto.

Claim 7

Assembly according to claim 4, including an insulating member located at one side of said channel member, and a sealing disc interposed therebetween for closing off the transverse bores formed in said channel member.

Claim 8

Assembly according to claim 6, wherein said sealing disc is formed with a flange, and said flange is, in turn, formed with an annular groove on the side thereof facing said channel member for receiving a seal therein.

Claim 9

Assembly according to claim 6, having at least two disc cells connected electrically in series, wherein one channel member and two cooling pans disposed on said flat sides, respectively, of said channel member are located between said series-connected disc cells, respectively.

Claim 10

Assembly according to claim 8 having a bearing in the form of a screw threadedly secured in a thread formed in the framework, and including a buffer member having an end portion facing said stack of members, said buffer member being displaceable relative to said bearing, said bearing and said buffer having stops for limiting end positions of said buffer relative to said bearing, said force-storing device being clamped between a stop of said buffer and a shoulder of said bearing.

Claim 11

Assembly according to claim 9, wherein said bearing is formed with a hollow space in which said force-storing device and a predominant portion of said buffer are received.
