Abstract
Abstract A heat conducting thermal plate (55) is fixed to a thermal load (10) by means of fasteners (75). Bosses (60) on the thermal plate are received within bosses (75) on an adjacent heat exchanger (25) to maintain a sealed interengagement between those components as the thermal plate is drawn up into surface-to-surface contact with the load.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
180 words
In an arrangement for mounting a thermal load to a heat exchanger having an outer wall and adapted for cooling said load, a heat conductor disposed between said heat exchanger and load for conducting heat from said load to said heat exchanger, and fasteners for attaching said heat conductor to said load, the improvement characterized by: said heat conductor being spaced from said heat exchanger outer wall and defining therewith, a conduit which accommodates fluid flow therebetween; first and second elongate locators on said heat exchanger outer wall and heat conductor respectively, said locators being interengageable with one another over a range of relative spacings between said heat exchanger outer wall and heat conductor; and first resilient sealing means disposed between said first and second locators for sealing said locators to one another, whereby clearances between said heat conductor and load may be taken up by drawing said heat conductor away from said heat exchanger outer wall, into firm contact with said load, without risk of leakage of said fluid from between said heat conductor and heat exchanger outer wall.
Claim 2
Dependent Claim
180 words
In an arrangement for mounting a thermal load to a heat exchanger having an outer wall and adapted for cooling said load, a heat conductor disposed between said heat exchanger and load for conducting heat from said load to said heat exchanger, and fasteners for attaching said heat conductor to said load, the improvement characterized by: said heat conductor being spaced from said heat exchanger outer wall and defining therewith, a conduit which accommodates fluid flow therebetween; first and second elongate locators on said heat exchanger outer wall and heat conductor respectively, said locators being interengageable with one another over a range of relative spacings between said heat exchanger outer wall and heat conductor; and first resilient sealing means disposed between said first and second locators for sealing said locators to one another, whereby clearances between said heat conductor and load may be taken up by drawing said heat conductor away from said heat exchanger outer wall, into firm contact with said load, without risk of leakage of said fluid from between said heat conductor and heat exchanger outer wall.
Claim 3
Dependent Claim
44 words
The arrangement of claim 1 characterized by said first locator comprising a first, hollow boss extending inwardly from said heat exchanger outer wall, and said second locator comprising a second boss extending outwardly from said heat conductor and slidably received within said first boss.
Claim 4
Dependent Claim
38 words
The arrangement of claim 1 characterized by said fasteners comprising elongate fasteners extending from said load, outwardly, through said second boss and being accessible from the exterior of said heat exchanger at the interior of said first boss.
Claim 5
Dependent Claim
25 words
The arrangement of claim 2 characterized by said first resilient sealing means comprising at least one O-ring seal disposed between said first and second bosses.
Claim 6
Dependent Claim
85 words
The arrangement of claim 1 characterized by said mounting arrangement including: a frame; a retaining member fixed to said frame on an opposite side of said heat conductor as said heat exchanger outer wall; and a second resilient sealing means fixed to said retaining member and engaged with said heat conductor, thereby biasing said heat conductor toward said heat exchanger for ease in retraction of said heat conductor from said load and for sealing said heat exchanger fluid from contact with said heat exchanger fluid.
Claim 7
Dependent Claim
37 words
The arrangement of claim 5 characterized by: said retaining member comprising a plate having a gland therein, and said second resilient sealing means comprising a gasket formed from a closed cell foam and disposed within said gland.
Claim 8
Dependent Claim
36 words
The arrangement of claim 1 characterized by said heat exchanger including a plurality of spaced cooling fins, said cooling fins being provided on an outer surface of said heat conductor and extendable into said fluid conduit.
