Abstract
Abstract There is provided a single-tank X-ray unit having a closed cooling circuit arranged in a housing for circulating a cooling agent to discharge the heat generated in the anode. The cooling circuit includes a feed duct and a return duct respectively wound helically around the high-voltage generator. A fan is so positioned in the housing as to pass cooling air over the cooling circuit, the housing having openings respectively for the intake of the cooling air and the discharge of the same.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
115 words
A single-tank X-ray unit for continuous operation, which comprises a unitary housing; an X-ray tube including an anode and an associated high-voltage generator both arranged in said housing; a closed cooling circuit also arranged in said housing for circulating a cooling agent to discharge the heat generated in the anode; a fan positioned in said housing for passing cooling air over the cooling circuit to cool the same, the cooling circuit including a feed duct and a return duct for the cooling agent respectively wound helically around the high-voltage generator and cooled by the cooling air; and openings provided in said housing respectively for the intake thereinto and the discharge therefrom of said cooling air.
Claim 2
Dependent Claim
115 words
A single-tank X-ray unit for continuous operation, which comprises a unitary housing; an X-ray tube including an anode and an associated high-voltage generator both arranged in said housing; a closed cooling circuit also arranged in said housing for circulating a cooling agent to discharge the heat generated in the anode; a fan positioned in said housing for passing cooling air over the cooling circuit to cool the same, the cooling circuit including a feed duct and a return duct for the cooling agent respectively wound helically around the high-voltage generator and cooled by the cooling air; and openings provided in said housing respectively for the intake thereinto and the discharge therefrom of said cooling air.
Claim 3
Dependent Claim
77 words
A single-tank X-ray unit according to claim 1, in which the cooling circuit includes a cylindrical chamber connected respectively to the feed duct and the return duct and thermally coupled to the anode; and elongate cooling member connected to the anode and extending longitudinally into said cylindrical chamber; and a separator in the cylindrical chamber for directing the cooling agent from the feed duct into contact with said cooling member and then out into the return duct.
Claim 4
Dependent Claim
25 words
A single-tank X-ray unit according to claim 2, in which the separator has a tubular shape, and the cooling member projects into said tubular separator.
