A two-phase cooling device

Abstract

The embodiment of the invention discloses a two-phase cooling device used for achieving natural heat dissipation and air cooling, and effectively improving efficiency of the natural heat dissipation and performance of wind and sand prevention. The two-phase cooling device comprises a condenser and a fan. The fan is arranged at the top or the bottom of the two-phase cooling device, and the condenser is arranged in the two-phase cooling device in an inclined or perpendicular mode. The two-phase cooling device further comprises a first air opening formed corresponding to the fan in position, and the condenser is arranged between the fan and the first air opening. Shutters are arranged around the condenser and connected through link mechanisms. An air cylinder is further arranged on the shutters and used for controlling the shutters to open or close. The two-phase cooling device further comprises a second air opening formed in the position the same as that of the fan. A gravity shutter is installed on the air outlet of the fan. Through control over the two-phase cooling device, the two-phase cooling device can be made to form a natural heat dissipation state or form a forced air cooling air channel.

Description

Technical field [0001] The invention relates to technology in the fields of machinery, communication and energy, and in particular to a two-phase cooling device for preventing wind and sand. Background technique [0002] The condenser is an important part of the gas-liquid two-phase heat exchange system, which serves the purpose of condensing steam in the system. After the high-temperature steam passes through the condensing tube, the heat is transferred to the radiating fins through the condensing tube, and then dissipated into the air through the convection heat exchange between the fins and the air, thereby reducing the steam temperature and achieving the purpose of condensation. For high-power condensers used in outdoor environments, due to the large heat consumption of the system, the smaller installation space of the condenser, and the relatively harsh working environment, the requirements for the condenser's heat exchange performance, wind and sand resistance and long-term...
