Abstract

A housing assembly and a method of manufacturing the housing assembly. The housing assembly includes a trap portion and a heat transfer portion. A first plate member of the heat transfer portion has one or more first and second flanges having a length L 1 and L 2 . A second plate member of the heat transfer portion has one or more first and second flanges having a length L 3 and L 4 that are larger than the lengths L 1 and L 2 . At least a portion of the one or more first and second flanges of the first plate member are integrally connected to at least a portion of said one or more first and second flanges of said second plate member. Additionally, at least a portion of the one or more first and second flanges of the second plate member are overmoulded within the tray portion of the housing assembly.

First claim

What is claimed is:

1. A housing assembly, comprising:
a tray portion;
a heat transfer portion comprising a first plate member and a second plate member;
wherein said first plate member has an inner surface, an outer surface, a first end portion a second end portion and an intermediate portion interposed between said first and second end portions of said first plate member;
wherein said first end portion of said first plate member has one or more first flanges having a length L 1 and said second end portion of said second plate member has one or more second flanges having a length L 2 ;
wherein said second plate member has an inner surface, an outer surface, a first end portion, a second end portion and an intermediate portion interposed between said first and second end portions of said second plate member;
wherein said first end portion of said second plate member has one or more first flanges having a length L 3 and said second end portion of said second plate member has one or more second flanges having a length L 4 ;
wherein said length L 1 and L 2 of said one or more first and second flanges of said first plate member are smaller than said lengths L 3 and L 4 of said one or more first and second flanges of said second plate member;
wherein at least a portion of said one or more first and second flanges of said first plate member are integrally connected to at least a portion of said one or more first and second flanges of said second plate member; and
wherein at least a portion of said one or more first and second flanges of said second plate member are overmoulded within at least a portion of said tray portion.

2. The housing assembly of claim 1 , wherein said first plate member further comprises an outwardly extending portion and said second plate member further comprises an outwardly extending portion;
wherein said outwardly extending portion of said first plate member extends from at least a portion of said intermediate portion of said first plate member away from said first plate member;
wherein said outwardly extending portion of said second plate member extends from at least a portion of said intermediate portion of said second plate member away from said second plate member; and
wherein said outwardly extending portion of said first plate member is aligned with said outwardly extending portion of said second plate member defining one or more fluid passages.

3. The housing assembly of claim 2 , wherein said outwardly extending portion of said first plate member has a height β;
wherein a portion of said one or more first flanges of said second plate member have one or more first clamping regions having a length L 5 and said one or more second flanges of said second plate member have one or more second clamping regions having a length L 6 ;
wherein L 5 ≥½β; and
wherein L 6 ≥½β.

4. The housing assembly of claim 2 , wherein said outwardly extending portion of said first plate member has a height β;
wherein said one or more first flanges of said second plate member have a length L 7 extending from an axially outermost end of said one or more first flanges of said first plate member to an axially outermost end of said one or more first flanges of said second plate member;
wherein said one or more second flanges of said second plate member have a length L 8 extending from an axially outermost end of said one or more second flanges of said first plate member to an axially outermost end of said one or more second flanges of said second plate member;
wherein L 7 ≤10×β; and
wherein L 8 ≤10×β.

5. The housing assembly of claim 1 , wherein said tray portion of said housing assembly comprises one or more axially extending portions and one or more radially extending portions; and
wherein at least a portion of said one or more first and/or second flanges of said second plate member are overmoulded within at least a portion of said one or more axially extending portions of said tray portion of said housing assembly.

6. The housing assembly of claim 1 , further comprising one or more electro-chemical cells; and
wherein said one or more electro-chemical cells are received and/or retained within at least a portion of said tray portion of said housing assembly.

7. The housing assembly of claim 6 , wherein said one or more electro-chemical cells are one or more battery cells, one or more rechargeable battery cells, one or more lithium-ion battery cells.

8. The housing assembly of claim 1 , further comprising one or more thermal expansion and contraction compensating members;
wherein said one or more thermal expansion and contraction compensating members extend along at least a portion of said inner surface and said outer surface of an axially outermost end of said one or more first and second flanges of said second plate member;
wherein at least a portion of said one or more thermal expansion and contraction compensating members are overmoulded within at least a portion of said tray portion of said housing assembly; and
wherein said one or more thermal expansion and contraction compensating members allow for a pre-determined amount of thermal expansion and contraction between said one or more first and second plate members of said heat transfer portion and said tray portion of said housing assembly.

9. The housing assembly of claim 8 , wherein said one or more thermal expansion and contraction compensating members are composed of a rubber composition, a polymeric composition, an elastomeric composition and/or a composite material.

10. The housing assembly of claim 1 , further comprising one or more first thermal expansion and contraction compensating members and one or more second thermal expansion and contraction compensating members;
wherein at least a portion of said one or more first thermal expansion and contraction compensating members are integrally connected to at least a portion of said outer surface of said one or more first and second flanges of said second plate member;
wherein at least a portion of said one or more second thermal expansion and contraction compensating members are integrally connected to at least a portion of said inner surface of said one or more first and second flanges of said second plate member;
wherein at least a portion of said one or more first and second thermal expansion and contraction compensating members are overmoulded within at least a portion of said tray portion of said housing assembly; and
wherein said one or more first and second thermal expansion and contraction compensating members allow for a pre-determined amount of thermal expansion and contraction between said one or more first and second plate members of said heat transfer portion and said tray portion of said housing assembly.

11. The housing assembly of claim 10 , wherein said one or more first and second thermal expansion and contraction compensating members are composed of a rubber composition, a polymeric composition, an elastomeric composition and/or a composite material.

12. The housing assembly of claim 1 , further comprising one or more apertures;
wherein said one or more apertures extend from an inner surface to an outer surface of said one or more first and second flanges of said second plate member; and
wherein at least a portion of said tray portion is overmoulded over at least a portion of said one or more apertures within said one or more first and second flanges of said second plate member.
