HEAT DISSIPATION DEVICE FOR TRACTION MACHINE

WIPO Patent Application WO/2019/091213

A1

A heat dissipation device for a traction machine, pertaining to the technical field of elevator equipment. A refrigerant liquid storage chamber (2) is provided within a housing (1). A cooling plate mechanism (4) and a temperature detection sensor (5) employing liquid level detection are provided within the refrigerant liquid storage chamber (2). A heat dissipating fan (3) is provided at a lower left end of an interior of the housing (1). The heat dissipating fan (3) is connected to a heat dissipating pipe at one side thereof, and a gas dryer (7) is installed on the heat dissipating pipe. The heat dissipating pipe is with a traction wheel heat-dissipating cover (9) and a traction machine heat-dissipating cover (10) via a three-way connector. A smart controller (6) is installed on a side wall of the housing (1). The temperature detection sensor (5) employing liquid level detection and an external temperature sensor (8) are connected to input ends of the smart controller (6). Output ends of the smart controller (6) are connected to the heat-dissipating fan (3) and the cooling plate mechanism (4), respectively. The heat dissipation device for a traction machine achieves fast heat dissipation, improves service life, is easy to operate and highly efficient, and saves time.
