Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
80 words
In a blowthrough evaporative heat exchanger including a blower, means defining a region for the introduction of air, means to gravitate water throughout substantially all of the cross section of said region, air guiding means extending from said blower into said region, said guiding means including an upper wall in a position to be impinged upon by on the end of and extending below said water baffle being small in relation to the cross section of the air guiding means.
Claim 2
Dependent Claim
80 words
In a blowthrough evaporative heat exchanger including a blower, means defining a region for the introduction of air, means to gravitate water throughout substantially all of the cross section of said region, air guiding means extending from said blower into said region, said guiding means including an upper wall in a position to be impinged upon by on the end of and extending below said water baffle being small in relation to the cross section of the air guiding means.
Claim 3
Dependent Claim
27 words
The apparatus as claimed in claim 1 in which said baffle has a brake therein such that the outer end is lower than the inner end thereof.
Claim 4
Dependent Claim
97 words
In a blowthrough evaporative heat exchanger including a blower, means defining a region for the introduction of air, means to gravitate water throughout the cross section of said region, ducting extending from said blower into said region in a position to be impinged upon by said water, said ducting including a water baffle extending from its upper wall and projecting beyond and below the end of said upper wall within said region, the area of said water baffle projecting below the end of said upper wall being small in relation to the cross section of the ducting.
Claim 5
Dependent Claim
97 words
In a blowthrough evaporative heat exchanger including a blower, means defining a region for the introduction of air, means to gravitate water throughout the cross section of said region, ducting extending from said blower into said region in a position to be impinged upon by said water, said ducting including a water baffle extending from its upper wall and projecting beyond and below the end of said upper wall within said region, the area of said water baffle projecting below the end of said upper wall being small in relation to the cross section of the ducting.
Claim 6
Dependent Claim
32 words
The apparatus as claimed in claim 3 in which said ducting is of rectangular cross section and said water baffle extends for the full width of the upper wall of said duct.
Claim 7
Dependent Claim
154 words
Evaporative heat exchange apparatus comprising a chamber, a region of said chamber having therein surface presenting means for receiving fluid to have heat evaporatively extracted therefrom, means above said region to flow liquid by gravity over said surface presenting means, means defining a V-section sump below said region to receive liquid falling from said surface presenting means, said sump having a wall inclined outwardly from the bottom and a vertical wall at least one of which is part of the sump-defining means, an air blower, ducting leading from the outlet of said blower through said inclined wall and terminating with its mouth facing said vertical wall, a water baffle extending from the upper wall of said ducting and projecting beyond said mouth and below the upper defining edge thereof, the area of said water baffle projecting below the end of said upper wall being small in relation to the cross section of the ducting.
