Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
121 words
A heat-exchange system for a power plant installation, especially for a motor vehicle, including a liquid-cooled internal-combustion engine, a first heat-exchanger associated with the engine and through which engine coolant circulates, a second liquid-circulating means associated with the installation, a second heat-exchanger through which secondary means liquid circulates and disposed in juxtaposed relation to the first exchanger so that air passes through the exchangers in series, and means detachably mounting one exchanger relative to the other, characterized in that the mounting means comprises track means slidably supporting the one exchanger relative to the other for movement into and out of said juxtaposed relation, and releasable securing means cooperative with the track means for normally securing the exchangers in said juxtaposed relation.
Claim 2
Dependent Claim
121 words
A heat-exchange system for a power plant installation, especially for a motor vehicle, including a liquid-cooled internal-combustion engine, a first heat-exchanger associated with the engine and through which engine coolant circulates, a second liquid-circulating means associated with the installation, a second heat-exchanger through which secondary means liquid circulates and disposed in juxtaposed relation to the first exchanger so that air passes through the exchangers in series, and means detachably mounting one exchanger relative to the other, characterized in that the mounting means comprises track means slidably supporting the one exchanger relative to the other for movement into and out of said juxtaposed relation, and releasable securing means cooperative with the track means for normally securing the exchangers in said juxtaposed relation.
Claim 3
Dependent Claim
21 words
The invention defined in claim 1, further characterized in that the track means includes spaced apart pairs of cooperative track elements.
Claim 4
Dependent Claim
53 words
The invention defined in claim 2, further characterized in that one element of each pair includes a tubular portion and the cooperative element of each pair includes a complementarily shaped portion and the releasable means for eaCh pair includes a fastener removably carried by one element and engageable normally with the cooperative element.
Claim 5
Dependent Claim
43 words
The invention defined in claim 3, further characterized in that each tubular element is elongated along the length of the track means and has opposite internally threaded end parts, and each fastener is externally threaded to fit removably into the respective end parts.
Claim 6
Dependent Claim
28 words
The invention defined in claim 2, further characterized in that the elements of each pair are relatively adjustable in order to improve the sliding relationship between the exchangers.
Claim 7
Dependent Claim
27 words
The invention defined in claim 2, further characterized in that the exchangers are disposed in parallel vertical planes and the track elements are upper and lower pairs.
Claim 8
Dependent Claim
64 words
The invention defined in claim 6, further characterized in that the first exchanger is vertical and is mounted ahead of the engine, the second exchanger is vertical and is mounted ahead of the first exchanger, one element of each pair is carried on the first exchanger in spaced apart parallel relationship and the other elements of the pair are carried on the second exchanger.
Claim 9
Dependent Claim
21 words
The invention defined in claim 7, further characterized in that the elements on the first exchanger are detachably and adjustably mounted.
Claim 10
Dependent Claim
51 words
The invention defined in claim 7, further characterized in that the second exchanger elements are each in the form of a strip having a rolled portion proximate to the first exchanger and parallel thereto and each element on the first exchanger is a J-shaped element cooperatively fitting the respective rolled portion.
Claim 11
Dependent Claim
45 words
The invention defined in claim 9, further characterized in that each of the opposite ends of each rolled portion is internally threaded and each fastener is a cap screw threaded into the associated rolled portion and abutting the respective end of the associated J-shaped portion.
