Technical Field
[0001] The utility model relates to the technical field of capillary pumps, in particular to a driving device of a thermal management system. Background Art
[0002] Thermal management system refers to the technology and equipment used to control and maintain the temperature and heat distribution of equipment or systems. It is mainly used in various fields such as electronic equipment, computer systems, industrial equipment, automobiles, etc.
[0003] When a satellite is flying in space, its own thermal management system is mostly driven by electricity, which consumes a lot of electric energy. Since the temperature difference between the sun-facing side and the shady side of the satellite is large, it will also affect the interior of the satellite. At present, there is no energy-saving and environmentally friendly driving device that can make good use of the temperature difference to drive the thermal management system. For this reason, a driving device for the thermal management system is proposed. Utility Model Content

[0006] The driving source comprises a heating tank, a cavity is arranged in the heating tank, a first one-way valve is connected to the top of the cavity, a compression tank is connected to the top of the first one-way valve, and a heat insulation frame is connected to one side of the heating tank.
[0007] Preferably, the heating tank and the compression tank are both arranged in a fan shape.
[0008] Preferably, one end of the cooling reflux pipe passes through the heat exchange mechanism and is connected to the heated tank, and one end of the exhaust pipe is connected to a check valve and is connected to the compression tank.
[0009] Preferably, the heat exchange mechanism comprises a heat exchange shell, a plurality of heat sinks are connected to one side of the inner wall of the heat exchange shell, an internal connection surface is connected to one side of the heat exchange shell, and a heat discharge / discharge joint is connected to one side of the internal connection surface.
[0010] Preferably, the exhaust pipe and the cooling return pipe are curved and penetrate through each of the heat sinks, and the heat exchange shell is filled with a heat exchange medium.
[0011] Preferably, mounting plates are connected to both sides of the driving source.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. The utility model installs the driving source on the sun-facing side of the communication satellite through the mounting plate, and installs the condensing mechanism on the side of the satellite. The heating tank heats the non-wetted medium in the cavity, and the non-wetted medium is heated and vaporized. The steam enters the compression tank through the first one-way valve for compression, and then is discharged through the compression tank. The hot steam enters the heat exchange shell through the compression tank, and the heat energy is transferred to the internal medium by each heat sink. The heat energy pipe and the medium supplement pipe in the satellite cabin are connected to the heat energy discharge / discharge joint, and the heat energy is transferred to the cabin for heating, which effectively reduces the internal energy consumption and fully meets the heat source consumption.
[0014] 2. The utility model also allows steam to pass through the heat exchange mechanism into the condensing mechanism, and then return through the cooling reflux pipe after being cooled and condensed. When the temperature in the heat exchange mechanism is too high, the temperature control valve opens, the second one-way valve closes, and the low-temperature medium flows into the heat exchange shell to neutralize the temperature for cooling. When the temperature in the heat exchange mechanism is normal, the temperature control valve closes, and the non-wetting medium condensed and refluxed bypasses the heat exchange mechanism through the separation tube and returns to the cavity, thereby effectively performing automatic temperature control without unnecessary energy loss and meeting the use requirements.
