Изобретение относитс к аккумул торам энергии жидкости и может быть, использовано в различных гидросистемах .The invention relates to a fluid energy accumulator and can be used in various hydraulic systems.

Известен пневмогидравлический аккумул тор , содержащий корпус с жидкостной и газовой, заполненной парожидкостной смесью полост ми, разделитель полостей, теплообмен ое устройство , выполненное в виде тепловой т|эу,д бки, частично размещенной в газовой полости fl .A pneumohydraulic accumulator is known, comprising a housing with a liquid and gas cavity filled with a vapor-liquid mixture, a cavity separator, a heat exchange device made in the form of a thermal fluid, partially located in the gas cavity fl.

Недостатком известного устройства вл етс то, что выход ща во внешнюю J5 среду часть теплообменного устройства требует введени дополнительного уплотнени в конструкцию аккумул тора, сама выступающа часть может быть подвержена воздействию коррозионноактив- 20 ной среды, случайным механическим воздействи м .A disadvantage of the known device is that the part of the heat exchanging device discharging into the external J5 environment requires the introduction of additional compaction into the battery design, the protruding part itself may be exposed to a corrosive environment, random mechanical effects.

Цель изобретени - повышение надежности пневмогидравлического аккумул тора и улучшение его эксплуатационных свойств.The purpose of the invention is to increase the reliability of the pneumohydraulic battery and improve its performance properties.

Эта цель достигаетс тем, что друга часть теплообменного устройства размещена в жидкостной полости.This goal is achieved by the fact that another part of the heat exchanging device is located in the liquid cavity.

Кроме того, теплова трубка может быть выполнена в виде разделител полостей .In addition, the heat pipe can be made in the form of a cavity separator.

Также теплова трубка и корпус могут быть установлены коаксиально с прилеганием внутренней поверхности последнего к наружной поверхности трубки .Also, the heat pipe and housing can be installed coaxially with the fit of the inner surface of the latter to the outer surface of the tube.

К тому же теплова трубка может быть установлена в корпусе с зазором относительно его стенки, и разделитель сред расположен внутри трубки.In addition, the heat pipe can be installed in the housing with a gap relative to its wall, and the media separator is located inside the pipe.

Claims

FIG. 1 shows a pneumohydraulic accumulator with a heat pipe in the form of a cavity separator: FIG. 2 - an accumulator with a heat pipe installed coaxially to the body with the latter adhered to the outer surface of the tube: in FIG. 3 battery with heat pipe installed in the housing with a gap relative to its wall. The battery contains a housing. 1, a liquid cavity 2, a gas cavity 3, a separator k of cavities, a heat exchange device 5. The gas cavity 3 is filled with a vapor-liquid mixture, such as carbon dioxide, at a pressure corresponding to the phase transition boundary of the Heat exchange device 5, made in the form of a sealed, partially filled with light scale liquid heat pipe. Pneumohydraulic battery operates as follows. In the liquid cavity 2, the working fluid is supplied under pressure. In the process of charging the battery, an increase in pressure occurs, the medium being compressed in the gas cavity 3 is heated, and steam is also condensed, which is also accompanied by heat release. Condensation occurs on the coldest element, which is the surface of the heat exchanging device 5, in contact with the vapor-liquid mixture. FIG. 1 this surface is the outer surface of the separator located in the gas cavity half. In FIG. 2, this surface is the internal surface of the heat exchanging device 5 located above the separator k in the gas cavity 3, and FIG. 3 is the outer surface of the heat exchanging device 5 located below the boundary between the gas and liquid media. The heat released in this process is intensively removed to that part of the heat exchange device 5, which is located in the liquid cavity 2, and then transferred to the working fluid. Selected during condensation, the liquid phase accumulates on the heat exchanger 59 Located in the gas strip 3. When the battery is discharged and it does useful work, the gas in the gas cavity 3 expands, accompanied by a decrease in temperature and pressure in it. The decrease in pressure is compensated by the evaporation of the vapor-liquid mixture phase. Heat spent on evaporation and temperature equalization in liquid band 2 and gas cavity 3 is intensively supplied by heat exchanger 5. As a result, the pressure differential between the beginning and end of discharge decreases and external work increases. The execution of the heat exchanging device 5 inside the housing placed in the liquid cavity 2 and in the gas cavity 3 at the same time, in the form of a heat pipe, as well as in a known accumulator, will ensure a high heat flow density between the heat exchange zones, in particular between the liquid cavity 2 and gas cavity 3 of the battery, which brings the processes of charging and discharging the battery to isothermal and leads to stabilization of pressure, to an increase in the energy accumulated and released by the battery. Placing the heat exchanger in the battery case and the absence of any parts of this device outside the case will improve the reliability and improve the performance properties of the battery. Claim 1 o A pneumatic-hydraulic accumulator comprising a housing with a liquid and gas cavity filled with a vapor-liquid mixture, a cavity separator, a heat exchange device made in the form of a heat pipe partially placed in the gas cavity, which is designed to increase reliability and improving the performance properties, the other part of the heat exchanging device is located in the liquid cavity. 2 A battery according to claim 1, wherein the heat pipe is made in the form of a cavity separator. 3. The accumulator according to claim 1, characterized in that the heat pipe and the housing are mounted coaxially with the fit of the inner surface of the latter to the outer surface of the tube. 4. The accumulator according to claim 1, which is based on the fact that the heat pipe is installed in the housing with a gap relative to its wall, and (the cavity separator is located inside the tube.
