Abstract
Abstract A cooling system for electricity generating equipment comprises an enclosure having two compartments, a generator and electrical components being arranged in one compartment and an engine which drives the generator in the other compartment, a duct being provided leading from the upper part of the enclosure through which warm air from within the enclosure will pass to an outlet, and an exhaust pipe from the engine being introduced into this duct and extending along it, the exhaust pipe terminating within the duct and the internal bore of the duct having a venturi restriction in the region of the end of the exhaust pipe.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
123 words
The combination with an electricity generating equipment having a generator and an engine driving the said generator, of an enclosure for said generator and engine, an outlet duct leading from the said enclosure whereby warm air from within the enclosure will pass through the outlet duct, exhaust means leading from the engine into the outlet duct and terminating within the outlet duct, the duct having an internal bore and a venturi restriction in said bore, the venturi restriction being situated in the region of the termination of the exhaust means, whereby in use exhaust gases issuing under pressure from the exhaust pipe will promote a strong flow of air along the duct and thus a scavenging effect on the interior of the enclosure.
Claim 2
Dependent Claim
123 words
The combination with an electricity generating equipment having a generator and an engine driving the said generator, of an enclosure for said generator and engine, an outlet duct leading from the said enclosure whereby warm air from within the enclosure will pass through the outlet duct, exhaust means leading from the engine into the outlet duct and terminating within the outlet duct, the duct having an internal bore and a venturi restriction in said bore, the venturi restriction being situated in the region of the termination of the exhaust means, whereby in use exhaust gases issuing under pressure from the exhaust pipe will promote a strong flow of air along the duct and thus a scavenging effect on the interior of the enclosure.
Claim 3
Dependent Claim
40 words
Apparatus as claimed in claim 1 having an internal division in the enclosure, the division forming two compartments, the engine being contained in one compartment and the generator in the other, and each compartment having air intake and outlet means.
Claim 4
Dependent Claim
101 words
An electricity generating equipment and cooling system as claimed in claim 1 comprising a mounting frame, a dusttight enclosure over said frame, a vertical division in the enclosure forming two separate compartments, an alternator in one compartment, an engine for driving the alternator in the other compartment, air intake and outlet panels on each compartment, a roof on the enclosure, said outlet duct leading from the engine compartment through said roof, an exhaust pipe leading from the engine into the outlet duct, a nozzle end on said exhaust pipe and said end being situated in the region of said venturi restriction.
