Abstract

The present disclosure relates to an energy module having a plurality of energy generating cells, and at least one cooling plate having opposing surfaces. The cooling plate is disposed between an adjacent pair of the energy generating cells such that the opposing surfaces of the cooling plate are in contact with surfaces of the adjacent pair of energy generating cells. The cooling plate has at least one coolant flow channel configured to receive a coolant flow therethrough to limit propagation of heat from one to the other of either one of the adjacent pair of energy generating cells when either one of the adjacent pair of energy generating cells fails.

First claim

What is claimed is:

1. An energy module comprising:
a plurality of energy generating cells;
a plurality of cooling plates, each one of said cooling plates having flat, opposing surfaces, and pairs of the plurality of cooling plates being disposed on opposing sides of ones of said plurality of energy generating cells to sandwich each one of said energy generating cells therebetween, and further such that the opposing surfaces of each one of said plurality of cooling plates are in contact with surfaces of an adjacent pair of said energy generating cells;
each one of said plurality of cooling plates including:
a plurality of spaced apart coolant flow channels each configured to receive a coolant flow therethrough to limit propagation of heat from one to the other of either one of the adjacent pair of energy generating cells when either one of the adjacent pair of energy generating cells fails;
an independent, elongated, tubular inlet manifold having a slit running along a length thereof, the slit having a width corresponding to a thickness of the cooling plate to be able to receive a first edge portion of a first lateral side of the cooling plate in the slit, with an interior area of the inlet manifold communicating with each one of the plurality of spaced apart coolant flow channels along a first lateral side of the cooling plate, and supplying the coolant flow to the plurality of spaced apart coolant flow channels;
an independent, elongated, tubular outlet manifold communicating with each one of the plurality of spaced apart coolant flow channels along a second lateral side of the cooling plate, and receiving the coolant flow from the plurality of spaced apart coolant flow channels;
a first supply manifold configured to supply only a first subplurality of alternating ones of said independent, elongated tubular inlet manifolds associated with a first subplurality of said cooling plates from first sides thereof, such that said coolant flow flows in a first direction through said first subplurality of cooling plates;
a second supply manifold configured to supply only a second subplurality of different alternating ones of said independent elongated tubular inlet manifolds associated with a second subplurality of said cooling plates from first sides thereof, such that said coolant flow flows in a second direction opposite to said first direction through said second subplurality of cooling plates;
a first return manifold in communication with ones of the independent, elongated, tubular outlet manifolds associated with the first subplurality of said cooling plates at the second side of said first subplurality of said cooling plates; and
a second return manifold in communication with the second subplurality of different alternating ones of said independent elongated tubular manifolds associated with the second subplurality of said cooling plates, at the first sides of second subplurality of cooling plates.

2. The energy module of claim 1 , wherein ones of the plurality of spaced apart coolant flow channels are arranged parallel to one another and spaced apart.

3. The energy module of claim 1 , wherein each one of said plurality of cooling plates comprises a first wall portion having material portions removed to help form the plurality of spaced apart coolant flow channels, and a second wall portion secured to the first wall portion to fully form the plurality of spaced apart coolant flow channels therein.

4. The energy module of claim 3 , wherein the second wall portion also includes material portions removed therefrom which, when the second wall portion is placed against the first wall portion, forms the plurality of spaced apart coolant flow channels.

5. The energy module of claim 2 , further comprising: an inlet port fitting for connecting the independent, elongated, tubular inlet manifolds of said plurality of cooling plates to a supply source of the coolant flow; and
an outlet port fitting for channeling the coolant flow out from the plurality of cooling plates.

6. The energy module of claim 2 , wherein the at least one cooling plate is comprised at least partially of at least one of nickel and copper.

7. The energy module of claim 1 , wherein:
each one of said plurality of cooling plates forms a planar component having a first height and a first width,
each one of said energy generating cells has a second height and a second width; and
the first height and the first width of each one of said plurality of cooling plates being approximately the same as the second height and the second width of each one of said energy generating cells.

8. The energy module of claim 1 , wherein: each one of said plurality of cooling plates has a first thickness;
each said adjacent pair of energy generating cells has a second thickness; and
the first thickness is no more than about 10% of the second thickness.

9. The energy module of claim 1 , wherein at least one of the plurality of spaced apart coolant flow channels comprises at least one of:
a linear flow path; and
a serpentine shape.

10. The energy module of claim 1 , wherein ones of the plurality of spaced apart coolant flow channels are arranged parallel to one another and comprise the same cross sectional shape and dimension, and extend from a first longitudinal edge to a second longitudinal edge of its associated said cooling plate.
