Abstract
Abstract A heat exchanger with resilient liquid accumulator comprises a pair of heater blocks back-to-back on opposite sides of heater elements and having oppositely outwardly opening grooves for a liquid to be heated. The grooves are closed by spring metal plates that are held in place by cover plates. The cover plates are recessed on the outer side of the spring metal plates to permit expansion of the spring metal plates. The assembly is held together in sandwich fashion by tie bolts.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
100 words
A heat exchanger comprising a heat exchange member, said heat exchange member having a recess therein for receiving a liquid to be heat exchanged, means for passing a liquid to be heat exchanged through said recess, a spring metal plate separate from said heat exchange member and closing said recess, resilient sealing means disposed between said spring metal plate and said heat exchange member, and a cover plate detachably secured to said heat exchange member and bearing against said spring metal plate in a direction to compress said sealing means between said heat exchange member and said spring metal plate.
Claim 2
Dependent Claim
100 words
A heat exchanger comprising a heat exchange member, said heat exchange member having a recess therein for receiving a liquid to be heat exchanged, means for passing a liquid to be heat exchanged through said recess, a spring metal plate separate from said heat exchange member and closing said recess, resilient sealing means disposed between said spring metal plate and said heat exchange member, and a cover plate detachably secured to said heat exchange member and bearing against said spring metal plate in a direction to compress said sealing means between said heat exchange member and said spring metal plate.
Claim 3
Dependent Claim
24 words
A heat exchanger as claimed in claim 1, said cover plate having a recess therein to accommodate outward deformation of said spring metal plate.
Claim 4
Dependent Claim
26 words
A heat exchanger as claimed in claim 2, the margins of said recess in said cover plate bearing against the margins of said spring metal plate.
Claim 5
Dependent Claim
42 words
A heat exchanger as claimed in claim 1, and bolt means extending through said heat exchange member and cover plate releasably to retain said heat exchange member and cover plate in assembled relation with said spring metal plate and sealing means therebetween.
Claim 6
Dependent Claim
53 words
A heat exchanger as claimed in claim 1, said recess comprising a plurality of parallel grooves in said heat exchange member, and a continuous groove in said heat exchange member surrounding but spaced outwardly from said parallel grooves and shallower than said parallel grooves, said sealing means being disposed in said continuous groove.
Claim 7
Dependent Claim
29 words
A heat exchanger as claimed in claim 5, the margins of said grooves being spaced from said spring metal plate in the undeformed condition of said spring metal plate.
Claim 8
Dependent Claim
51 words
A heat exchanger as claimed in claim 1, there being a pair of said heat exchange members disposed in back-to-back relation with said recesses opening outwardly away from each other, and means between said heat exchange members for establishing a temperature different from the temperature of the liquid in said recesses.
