Abstract
Abstract The proposed cooler has the form of a thermal tube (1) with zones (2 and 3) for evaporation and condensation, respectively, and outer fins (4) in the zone (3). The cooler has a casing (5) open at one side to admit a flow of gas, the casing accommodating fins (4) so that ends thereof form with a wall of the casing (5) at the other side a cavity (A) to reverse the flow of gas. Adjacent fins (4) are hermetically connected into pairs (6), and form passages (7, 8) between each pair and inside each pair. Provided at the walls of the inner passages (8) is a capillary porous lining (9) ends of which are in contact with a liquid medium (10).

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
146 words
A cooler having the form of a thermal tube (1) comprising an evaporation zone (2) in which heat is drawn off a substance to be cooled, and a condensation zone (3) having outer fins (4) passed over by a flow of gas, characterized in that it has a casing (5) open at one side for admitting a flow of gas and accommodating the fins (4) so that their ends define with a wall of the casing (5) at the other side a cavity (A) to reverse the flow of gas, adjacent fins (4) at the side of admission of the gas being connected hermetically into pairs (6) to form passages (7, 8) between each such pair and inside each such pair walls of the thus formed inner passages (8) having a capillary porous lining (9) ends of which are in contact with a liquid medium (10).
Claim 2
Dependent Claim
146 words
A cooler having the form of a thermal tube (1) comprising an evaporation zone (2) in which heat is drawn off a substance to be cooled, and a condensation zone (3) having outer fins (4) passed over by a flow of gas, characterized in that it has a casing (5) open at one side for admitting a flow of gas and accommodating the fins (4) so that their ends define with a wall of the casing (5) at the other side a cavity (A) to reverse the flow of gas, adjacent fins (4) at the side of admission of the gas being connected hermetically into pairs (6) to form passages (7, 8) between each such pair and inside each such pair walls of the thus formed inner passages (8) having a capillary porous lining (9) ends of which are in contact with a liquid medium (10).
Claim 3
Dependent Claim
19 words
A cooler as claimed in claim 1, characterized in that the casing (5) accommodates a vessel (11) containing water.
Claim 4
Dependent Claim
46 words
A cooler as claimed in claim 1, characterized in that holes (12) for discharging the used gas to the outside are provided at the casing (5) in the zones of the inner passages (8) at the point of hermetic connection of the fins (4) into pairs.
