DEVICE FOR REMOVING HEAT FROM HEAT DISSIPATION SYSTEMS (EMBODIMENTS)

摘要

The invention relates to radio engineering and can be used in systems for cooling heat releasing units in radio electronic equipment. A device for heat removal comprises heat-insulated evaporation chamber with heat-transfer agent and condensation chamber connected to each other by means of two heat-insulated pipes; the evaporation chamber is designed to be capable of heat removal from heat releasing units and is mounted below the condensation chamber; one of the heat-insulated pipes is designed to be capable of vapour transporting from the evaporation chamber to the condensation chamber, the second one is designed to be capable of liquid transporting from the condensation chamber to the evaporation chamber; the device is characterized by the equipment with additional chamber mounted on the level between the evaporation chamber and the condensation chamber and connected to the second heat-insulated pipe with the help of a control valve, and with a hydraulic motor mounted on the first heat-insulated pipe in the way its input is connected to the evaporation chamber and its output is connected to the condensation chamber; the control valve is designed to be capable of coupling the additional chamber to the condensation chamber for periodical filling of the additional chamber with liquid transported from the condensation chamber; or to be capable of coupling the additional chamber to the evaporation chamber for later emptying of the additional chamber and liquid transporting to the evaporation chamber; heat-transfer agent consists of, at least, two immiscible and chemically no reactive liquid components, one of them is a refrigerant that changes its state of aggregation from liquid to gaseous while heating during heat removal from heat releasing systems ensuring pressure difference in the evaporation chamber and the condensation chamber, and the second component does not change its state of aggregation and is transferred from the evaporation chamber to the condensation chamber while heating during heat removal from heat releasing systems due to pressure difference in these chambers. According to the first variant the device is equipped with the hydraulic motor mounted on the first heat-insulated pipe so that its input is connected to the evaporation chamber and its output is connected to the condensation chamber. According to the second variant the device is equipped with the hydraulic motor placed in the condensation chamber. The invention makes it possible to use energy from heat release giving the opportunity to increase the eco-friendliness and operating efficiency of the device.
