Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
182 words
A cooling system for cooling the inside of an enclosure, said system comprising: a housing defining a first chamber and an inlet and outlet for the first chamber for communication with the enclosure; a first cooling assembly secured to the housing and including evaporator means disposed in the first chamber for extracting heat from a fluid which flows from the enclosure through the inlet of the first chamber and condenser means for discharging the heat extracted by the evaporator means; and a second cooling assembly including a vortex tube with a hot portion, a cold portion, and a generator portion disposed between the hot and cold portions, the cold portion being in fluid communication with the enclosure; said second cooling assembly including temperature sensing means disposed proximate the inlet of the first chamber for sensing the temperature of fluid flowing into the first chamber from the enclosure and control means connected to the temperature sensing means for controlling the operation of the vortex tube so that the vortex tube operates at a predetermined temperature of the fluid flowing into the first chamber.
Claim 2
Dependent Claim
182 words
A cooling system for cooling the inside of an enclosure, said system comprising: a housing defining a first chamber and an inlet and outlet for the first chamber for communication with the enclosure; a first cooling assembly secured to the housing and including evaporator means disposed in the first chamber for extracting heat from a fluid which flows from the enclosure through the inlet of the first chamber and condenser means for discharging the heat extracted by the evaporator means; and a second cooling assembly including a vortex tube with a hot portion, a cold portion, and a generator portion disposed between the hot and cold portions, the cold portion being in fluid communication with the enclosure; said second cooling assembly including temperature sensing means disposed proximate the inlet of the first chamber for sensing the temperature of fluid flowing into the first chamber from the enclosure and control means connected to the temperature sensing means for controlling the operation of the vortex tube so that the vortex tube operates at a predetermined temperature of the fluid flowing into the first chamber.
Claim 3
Dependent Claim
36 words
The cooling system of claim 1, wherein the housing defines a second chamber for containing the condenser means and the vortex tube of the second cooling assembly and an inlet and outlet for the second chamber.
Claim 4
Dependent Claim
40 words
The cooling system of claim 2, further comprising first circulating means for circulating the fluid flowing into the first chamber from the enclosure through the first chamber, around the evaporator means and out through the outlet of the first chamber.
Claim 5
Dependent Claim
23 words
The cooling system of claim 3, wherein the first circulating means lies in the first chamber proximate the outlet of the first chamber.
Claim 6
Dependent Claim
40 words
The cooling system of claim 4, further comprising second circulating means for circulating a fluid disposed outside of the enclosure through the inlet of the second chamber, around the condenser means and out through the outlet of the second chamber.
Claim 7
Dependent Claim
23 words
The cooling system of claim 5, wherein the second circulating means lies in the second chamber proximate the outlet of the second chamber.
Claim 8
Dependent Claim
26 words
The cooling system of claim 1, wherein the distal end of the cold portion of the vortex tube lies proximate the outlet of the first chamber.
Claim 9
Dependent Claim
54 words
The cooling system of claim 1, wherein the evaporator means is one end of a heat pipe core having at least one tube with closed ends for containing an evaporating and condensing medium and fin means disposed around the tube, and wherein the condenser means is the opposite end of the heat pipe core.
Claim 10
Dependent Claim
123 words
In combination with an enclosure, a first and second cooling assembly in fluid communication with the enclosure, the first cooling assembly including evaporator means for extracting heat from a fluid which flows from the enclosure to the first cooling assembly and back to the enclosure and condenser means for discharging the heat extracted by the evaporator means, the second cooling assembly including a vortex tube with a cold portion for discharging a cold fluid into the enclosure, temperature sensing means for sensing the temperature of the fluid in the enclosure, and control means connected to the temperature sensing means for controlling the operation of the vortex tube so that the vortex tube operates at a predetermined temperature of the fluid in the enclosure.
Claim 11
Dependent Claim
123 words
In combination with an enclosure, a first and second cooling assembly in fluid communication with the enclosure, the first cooling assembly including evaporator means for extracting heat from a fluid which flows from the enclosure to the first cooling assembly and back to the enclosure and condenser means for discharging the heat extracted by the evaporator means, the second cooling assembly including a vortex tube with a cold portion for discharging a cold fluid into the enclosure, temperature sensing means for sensing the temperature of the fluid in the enclosure, and control means connected to the temperature sensing means for controlling the operation of the vortex tube so that the vortex tube operates at a predetermined temperature of the fluid in the enclosure.
Claim 12
Dependent Claim
167 words
A cooling system for cooling the inside of an enclosure, said system comprising: a housing defining a first chamber and an inlet and outlet for the first chamber for communication with the enclosure; a first cooling assembly secured to the housing and including evaporator means disposed in the first chamber for extracting heat from a fluid which flows from the enclosure through the inlet of the first chamber and condenser means for discharging the heat extracted by the evaporator means; and a second cooling assembly including a vortex tube with a hot portion, a cold portion, and a generator portion disposed between the hot and cold portions, the cold portion being in fluid communication with the enclosure; said second cooling assembly including temperature sensing means for sensing the temperature of fluid in the enclosure and control means connected to the temperature sensing means for controlling the operation of the vortex tube so that the vortex tube operates at a predetermined temperature of the fluid in the enclosure.
