Изобретение относитс к теплообмениымустановкам и может быть использовано в энергетической, химической и других отрасл х промышленности дл охлаждени вращающихс тепловыдел ющих устройств.The invention relates to heat exchange installations and can be used in the power, chemical and other industries of the industry for cooling rotating heat generating devices.

Известны центробежные тепловые трубы, внутренн полость которых выполнена в виде параболоида вращени , расшир ющегос в направлении зоны конденсации (1).Centrifugal heat pipes are known, the internal cavity of which is made in the form of a paraboloid of rotation extending towards the condensation zone (1).

Центробежные тепловые трубы не могут быть использованы в тех случа х, когда необходимо передавать тепло в радиальном направлении .Centrifugal heat pipes cannot be used in cases where it is necessary to transfer heat in the radial direction.

Наиболее близким техническим решением к за вленному изобретению вл етс центробежна теплова труба, содержаща герметичный корпус, наружна и внутренн стенки которого образуют кольцевую полость, частично заполненную теплоносителем, и осевой канал дл прохода хладагента |2.The closest technical solution to the claimed invention is a centrifugal heat pipe containing a hermetic body, the outer and inner walls of which form an annular cavity partially filled with heat carrier and an axial channel for the passage of the refrigerant | 2.

Недостатком известной тепловой трубы вл етс сравнительно мала термодинамическа эффективность, обусловленна слаборазвитой поверхностью теплообмена в зоне конденсации по сравнению с зоной испарени .A disadvantage of the known heat pipe is the relatively low thermodynamic efficiency due to the poorly developed heat exchange surface in the condensation zone as compared to the evaporation zone.

Целью изобретени вл етс увеличение термодинамической эффективности тепловой трубы.The aim of the invention is to increase the thermodynamic efficiency of the heat pipe.

Поставленна цель достигаетс тем, что на внутренней стенке в кольцевой полости размещены пустотелые лопасти, снабженные поперечными, относительно оси корпуса, вставкамн, примыкающими к внутренней стенке и частично перекрывающими сечение лопастей, а осевой канал в зоне лопастей разделен поперечной перегородкой, по обеThe goal is achieved by the fact that on the inner wall in the annular cavity there are hollow blades with transverse, relative to the axis of the body, inset, adjacent to the inner wall and partially overlapping the blades section, and the axial channel in the zone of the blades is divided by a transverse partition on both

Claims

The centrifugal heat pipe has an airtight housing 1 with an axial channel 2. The annular cavity between the outer wall 3 and the inner wall 4 of the particle housing is filled with coolant 5. On the inner wall 4 there are hollow blades 6, inside which are installed transverse inserts 7 that do not overlap sections of the cross section 8 The axial channel 2 is divided by a transverse partition 9, on either side of which windows 10 are made in the inner wall. The housing is supported on P. bearings. The centrifugal heat pipe operates as follows. When the housing rotates in bearings 11 on the peripheral part of the outer wall 3, to which heat is supplied, under the action of centrifugal forces, a layer of heat-transfer fluid 5 is formed, which is continuously evaporated. The vapor condenses on the surface of the inner wall and the blades 6, cooled by a refrigerant that flows through the axial channel, enters the windows 10 by one hundred {partition 9, passes inside the blades, wrapped around the insert 7, and leaves through the windows on the other side of the partition 9 into the axial channel. Under the action of centrifugal forces, the heat-transfer fluid is thrown onto the peripheral part of the outer wall. In the centrifugal heat pipe, by installing closed hollow blades through which coolant is pumped, a significant increase in the heat exchange surface in the condensation zone is achieved. This surface becomes commensurate with the heat exchange surface in the evaporation zone. Thereby, the thermodynamic efficiency of centrifugal heat pipes is significantly improved. Claims of the invention A centrifugal heat pipe comprising a hermetic body, the outer and inner walls of which form an annular cavity partially filled with coolant and an axial channel for the passage of chidydant, characterized in that, in order to increase thermodynamic efficiency, hollow walls are placed on the inner wall in the annular cavity the blades, provided with transverse, relatively main body, inserts adjacent to the inner wall and partially overlapping the blade section, and the axial channel in the area of the blade th divided by a transverse partition, on both sides of which are made in the inner wall of the window, interconnecting the blades volumes with the axial channel.
