Abstract
Abstract An improved mounting device for mounting heat exchanger elements in a motor vehicle, the mounting device including a shroud for containing and supporting heat exchangers elements and attachment members for removably securing the shroud to a selected supporting structure of a motor vehicle. The shroud includes an end wall having an opening therein, a continuous sidewall extending from the end wall for encasing the heat exchanger elements and having an open end, and circulation members for moving a cooling medium through the shroud, the medium being admitted through the open end of the sidewall and being discharged through the opening in the end wall.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
216 words
An improvement in a motor vehicle having a body, an engine compartment formed within said body, a heat exchanger area located within said engine compartment, and an external air intake duct defined by said body and leading into said heat exchanger area, said improvement comprising: a shroud located within said heat exchanger area, wherein said shroud is in direct air communication with said external air intake duct to receive air directly from said external air intake duct, and said shroud includes an air outlet defined by an endwall having a first opening and a second opening therein and a continuous sidewall extending from said endwall that defines an air inlet, said air inlet and said air outlet to allow an airflow therethrough; a heat exchanger for cooling a circulating fluid, wherein said heat exchanger is located within said shroud and positioned in the path of said airflow, said heat exchanger is enclosed by and solely supported by said shroud, said shroud extends forwardly and rearwardly of said heat exchanger to direct said airflow, and said shroud and said heat exchanger are removably attachable to said body as a single unit; and; circulation means for moving a cooling medium through said shroud, said cooling medium being admitted through said air inlet and discharged through said air outlet.
Claim 2
Dependent Claim
216 words
An improvement in a motor vehicle having a body, an engine compartment formed within said body, a heat exchanger area located within said engine compartment, and an external air intake duct defined by said body and leading into said heat exchanger area, said improvement comprising: a shroud located within said heat exchanger area, wherein said shroud is in direct air communication with said external air intake duct to receive air directly from said external air intake duct, and said shroud includes an air outlet defined by an endwall having a first opening and a second opening therein and a continuous sidewall extending from said endwall that defines an air inlet, said air inlet and said air outlet to allow an airflow therethrough; a heat exchanger for cooling a circulating fluid, wherein said heat exchanger is located within said shroud and positioned in the path of said airflow, said heat exchanger is enclosed by and solely supported by said shroud, said shroud extends forwardly and rearwardly of said heat exchanger to direct said airflow, and said shroud and said heat exchanger are removably attachable to said body as a single unit; and; circulation means for moving a cooling medium through said shroud, said cooling medium being admitted through said air inlet and discharged through said air outlet.
Claim 3
Dependent Claim
20 words
An improvement as claimed in claim 1, further including locational means for locationally positioning said heat exchanger within said shroud.
Claim 4
Dependent Claim
22 words
An improvement as claimed in claim 2, wherein said locational means includes an inwardly directed shoulder for receiving said heat exchanger thereagainst.
Claim 5
Dependent Claim
37 words
An improvement as claimed in claim 1, further including a seal means for sealing said heat exchanger against said shroud, said seal means inhibiting the flow of said cooling medium between said heat exchanger and said shroud.
Claim 6
Dependent Claim
24 words
An improvement as claimed in claim 4, wherein said seal means parametrically encases said heat exchanger and engages said sidewall along a continuous line.
Claim 7
Dependent Claim
35 words
An improvement as claimed in claim 1, wherein said circulation means includes: means for causing movement of said cooling medium; and means for directionally controlling the discharge of said cooling medium through said air outlet.
Claim 8
Dependent Claim
33 words
An improvement as claimed in claim 6, wherein: said means for causing movement includes impeller means; and said means for directionally controlling includes duct means communicating with said first opening in said endwall.
Claim 9
Dependent Claim
40 words
An improvement as claimed in claim 1, wherein said circulation means includes: means for causing movement of said cooling medium; and means for directionally controlling the discharge of said cooling medium through said first and second openings in said endwall.
Claim 10
Dependent Claim
75 words
An improvement as claimed in claim 8, wherein: said means for causing movement includes first impeller means for discharging said cooling medium through said first opening in said endwall, and second impeller means for discharging said cooling medium through said second opening in said endwall; and said means for directionally controlling includes first duct means communicating with said first opening in said endwall, and second duct means communicating with said second opening in said endwall.
Claim 11
Dependent Claim
38 words
An improvement as claimed in claim 1, wherein said sidewall extends forwardly beyond said heat exchanger to form means for removably attaching said shroud to a supporting structure of said motor vehicle proximate to said heat exchanger area.
