Description

Изобретение относитс к устройствам дл передачи тепла с изменением агрегатного состо ни промежуточного теплоносител и может примен тьс в различных област х техники, где необходима передача тепла снизу вверх в гравитационном поле.The invention relates to heat transfer devices with a change in the state of aggregation of an intermediate heat carrier and can be applied in various fields of technology where heat transfer from bottom to top in a gravitational field is necessary.

Известны тепловые трубы, содержащие внутренние цилиндрические вставки и предназначенные дл передачи тепла снизуHeat pipes are known that contain internal cylindrical inserts and are designed to transfer heat from below.

The disadvantage of such pipes is the reduction in heat transfer capacity during the release of non-condensable gas inside the pipes during its operation.

2J. Поглощение неконаенсирующегос газа в этой трубе производитс геттером, 2J. The absorption of non-non-converting gas in this pipe is produced by a getter,

Существенным недостатком указанной трубы вл етс ослабление сорбционной способности геттера в процессе работы, что приводит к снижению термодинамической эффективности тепловой трубы.enclosed in a cylindrical container of finely meshed mesh. A significant drawback of this pipe is the weakening of the getter sorption capacity during operation, which leads to a decrease in the thermodynamic efficiency of the heat pipe.

Цель изобретени - повышение термодинамической эффективности трубы при передаче тепла в направлении, противоположнок направлению сил гравитации. Это достигаетс тем, что в предлагаемой трубе днище стакана выполнено глухим, диаметром , большим диаметра стакана, и имеет на периферии буртик, обращенный в сторону зоны конденсации, а отверсти расположены на участках, примыкающим к торцу зоны конденсации и днищу, при этом на участке, примыкающем к днищу, отверсти расположены ниже кра буртика .The purpose of the invention is to increase the thermodynamic efficiency of the pipe by transferring heat in the direction opposite to the direction of gravitational forces. This is achieved by the fact that in the proposed pipe the bottom of the glass is made deaf, with a diameter greater than the diameter of the glass, and has a collar on the periphery facing the condensation zone, and the holes are located in areas adjacent to the end of the condensation zone and the bottom, while adjacent to the bottom, the holes are located below the edge of the collar.

Claims

The heat pipe comprises a housing 1 with zones 2-4 of evaporation, transportation and condensation, respectively. A cylindrical cup 5 is attached to the end of the condensation zone inside the pipe. In the side wall of the glass, at its attachment to the end of the condensation zone, b holes are made for the passage of steam and non-condensable gas. Bottom 7 glasses made deaf. The diameter of the bottom is larger than the diameter of the glass, and on the periphery of the bottom there is a flange 8 facing the condensation zone. Through holes 9 are made at the point of attachment of the bottom, in the side wall of the glass, for the exit of the KOHJ densitate, and these holes are located below the edge of the shoulder. In the non-operating state, the non-condensable gas, together with the vapor-phase coolant, is distributed throughout the pipe cavity. When heat is supplied, the non-condensing gas rises up to the condensation zone 4, and through the O7-hole 6 enters the inside of the bowl 5. Because the fastening of the bowl 5 to the end of the condensation zone 4 provides thermal contact with the cooled wall of the pipe, the vapor that enters inside the glass condenses on its walls and the resulting condensate flows downward, filling the bottom of the glass to the edges of the collar 8. In this case, the holes 9 are below the level of the condensate. The resulting hydraulic valve passes the excess condensate through the holes 9 and does not allow non-condensing gas. Gas outlet from glass 5 to the side. Condensation bones 4 through the openings 6 prevent the flow of steam that continuously enters the zone during operation of the heat pipe. This embodiment of the pipe provides an increase in thermodynamic efficiency in the allocation of non-condensation in the pipe .. ruytsegos gas and heat transfer in the opposite direction to the forces of gravity. Invention Formulation Heat pipe containing filled | a heat-sealed enclosure with an evaporation, condensation and transportation zone and a tube mounted along the pipe axis with openings on the side surface, attached with an open end to the Topwy condensation zone, which, in order to increase the loss of single-dynamic efficiency in heat transfer in the direction opposite to the direction of gravity, the bottom of the glass is made deaf, with a diameter greater than the diameter of the glass, and has a flange on the periphery facing the condensation zone, and the holes are located on the kah, adjacent to the end of the condensation zone and the bottom at the same time on the site, prnmykak dem to the bottom,. the holes are located below the edge of the collar.
