Title: COOLING DEVICE FOR MACHINE CABINET, AND MACHINE CABINET
Abstract:
Disclosed are a cooling device for a machine cabinet, and a machine cabinet. The cooling device comprises: a heat exchange coil (110), arranged on the air-outlet side of a machine cabinet; a liquid supply pipe (120), in communication with an output opening of a cooler (140) and an input opening of the heat exchange coil (110), and used for conveying a coolant output by the cooler (140) to the heat exchange coil; a liquid return pipe (130), in communication with an output opening of the heat exchange coil (110) and an input opening of the cooler (140), and used for enabling the coolant output by the heat exchange coil (110) to flow back to the cooler (140); the cooler (140), used for cooling the coolant flowing back from the liquid return pipe and then outputting the cooled coolant to the liquid supply pipe (120); a fan (150), arranged on the air-outlet side of the heat exchange coil (110), and used for forming an air flow in an air outlet direction; and a fan control board (160), arranged in an air flow direction, and used for controlling the fan to act so as to form the air flow. The circulating path of cooling air is shortened, and the heat dissipation efficiency of the machine cabinet and the machine room is improved.
