(54) ТЕПЛСПЕРЕДАЮЩЕЕ УСТРОЙСТВО (54) HEAT SPEED DEVICE

II

Изобретение относитс к теплотехнике и может быть использовано в качестве различных теплообменных и термостатирующих устройств.The invention relates to heat engineering and can be used as various heat exchanging and thermostatic devices.

Известно теплопередающее устройство, содержащее зоны испарени , транспортировани и конденсации, причем последн выполнена в виде параллельных ветвей, объединенных общим коллектором и к зоне конденсации подключен газовь1й резервуар 1 .A heat transfer device is known which contains evaporation, transportation and condensation zones, the latter being made in the form of parallel branches connected by a common collector and a gas tank 1 is connected to the condensation zone.

Однако Б случае возникновени пиковых тепловых нагрузок, например при стерилизации биореакторов, когда необходимо удалить термолабильный теплоноситель из зоны испарени , то это устройство неработоспособно.However, in case of occurrence of peak heat loads, for example, when sterilizing bioreactors, when it is necessary to remove the heat-sensitive heat carrier from the evaporation zone, this device is inoperative.

Наиболее близким к предлагаемому по технической сущности и достигаемому результату вл етс теплопередающее устройство, содержащее тепловые трубы с зонами испарени и конденсации, соединенные со стороны конденсации посрецством трубопровода 2.The closest to the proposed technical essence and the achieved result is a heat transfer device containing heat pipes with evaporation and condensation zones that are connected on the condensation side by the strength of the pipeline 2.

Однако в данном теплопередающем устройстве наличие инертного газа резко уменьшает интенсивность теплообмена в зоне конденсации, что 1фивод1гг к развитию теплопередающих поверхностей, увеличенкю габаритов и металлоемкости устройства , кроме того данному теплопередающему устройству щ)имущи недостатки вышеуказанного устройства.However, in this heat transfer device, the presence of inert gas sharply reduces the intensity of heat exchange in the condensation zone, which leads to the development of heat transfer surfaces, increasing the size and intensity of the device, and the disadvantages of the above device.

Claims

20 is filled with a cylinder and a moving element with a pressure medium controlled by a pulse from a control unit, the moving element being designed as a background force of 3.00 or as a reciprocating piston, and the condensation zone of each heat pipe is equipped with a tubular cooling coil. In addition, each heat pipe is made with an extensive evaporation zone united by a common collector. FIG. 1 schematically shows the proposed heat transfer device in FIG. 2 - a device with a piston inside a cylinder. The heat transfer device contains i heat pipes 1 and 2 with zones 3 and 4 of evaporation and condensation connected from the side of zones 4 of the kondeisatsy of the pipeline M of the pipeline S. 6. The device additionally contains the control unit 7, cylinder 8, which is enclosed in paccoMicy of the co-pipeline pipeline 5 and 1 WASHABLE under-conductor element O inside. and the cooling tubular coil 10 placed in the pipeline 5 above the cylinder 8 coaxially with: ... The space of the hydraulic cylinder 8 and the movable element 9 is filled with pressure medium controlled by impulse from the control unit 7 of the control unit. The movable elem 1t is made in the form of a force 11 or a port 12 of a reciprocating mixing unit with UITOKOM 13. The zone 4 of the condensation heat pipe is equipped with a tubular cooling coil 14 equipped with throttle valves 15. The operation of the heat transfer device is carried out as follows. When the heat load is applied to the evaporation zones 3, the thermal lube heat sink (for example, freon-11) evaporates and the steam moves to zone 4 where condensation (W cooling coils 14 condenses and the condensate returns to evaporation zones. When the heating load rises in the evaporation zone 3, the vapor that is displaced on the coils 14 is directed to pipeline 5, where it is condensed on the coil 10 and the condensate flows into the force ({11). In this case, the total contact surface of the heat-transfer fluid with the heat transfer surface into the zone x 3 is reduced} When the heat load in the evaporation zone 3 decreases, the pressure decreases accordingly, the sypchon 11 is removed and the heat transfer fluid from the sylphon 11 is transferred to the heat pipes 1 and 2 by heat transfer fluid 1J, hence the contact surface of the heat transfer fluid from the heat exchanger The temperature of the medium in the space between the cylinder and the bellows remains constant. In addition, in this heat transfer device, it is possible to enforce precise temperature control by force, by changing the pressure-environment in the space between the cylinder 8 and the bellows 11, by impulse from the control side 7, thereby compressing or unclamping the common surface of the liquid heat-labile heat transfer fluid with the heat transfer surface, or by forced movement of the substrate 12 inside the cylinder 8, also changes the total contact surface of the heat-transfer fluid with the heat transfer surface. ited. When it becomes necessary to remove the heat-sensitive heat carrier from the evaporation zone 3, the cooling medium in the coils 14 is prevented due to the overlap of the throttles 15 and non-condensing beds entering the pipeline 5, they are condensed on the coil 10 and merged into the bellows 11. Thus, the The execution of a heat transfer device allows to increase the intensity of heat exchange in the condensation zone, to increase the accuracy of forced thermal control.
