A kind of elevator control cabinet and cooling method

Abstract

The invention discloses an elevator control cabinet, and belongs to the field of elevators. The elevator control cabinet comprises a cabinet body of the elevator control cabinet, a controller arrangedon the outer wall of the cabinet body, and a cooling device, wherein the cooling device is welded to the bottom of the inner side of the cabinet body, and the cooling device is electrically connectedwith the controller; the cooling device comprises a switch room; the switch room is internally provided with a wet net and a draught fan; the draught fan is positioned on one side of the wet net; anautomatic inlet valve is arranged on the side, close to the wet net, of the switch room, and an automatic outlet valve is arranged on the side, close to the draught fan, of the switch room; the automatic inlet valve and the automatic outlet valve are electrically connected with the controller respectively; and when the temperature inside the cabinet body detected by the controller is higher than aset temperature, the cooling device is started. According to the elevator control cabinet disclosed by the invention, the temperature inside the cabinet body is cooled by the cooling device welded tothe bottom of the inner side of the cabinet body, the damage of various devices inside the cabinet body due to excess temperature inside the cabinet body cannot be caused, and the fault phenomena ofthe devices caused by excessive temperature are avoided, so that the service lives of the various device are prolonged, and the cost is reduced.

Description

technical field [0001] The present invention relates to the field of elevators, and more specifically, to an elevator control cabinet and a cooling method. Background technique [0002] The elevator control cabinet, as a device to control the operation of the elevator, is an electronic control device that installs various electronic devices and electrical components in a cabinet-shaped structure with safety functions. The control cabinet is a sheet metal frame structure, and the elevator control cabinet is equipped with a mounting plate, a frequency converter, and a wire slot. The control cabinet is generally placed in the elevator machine room and installed close to the wall of the machine room. [0003] However, when the control cabinet is installed close to the wall, it will lead to poor heat dissipation of the elevator control cabinet, which is prone to failure and shortens the service life, thus causing the disadvantage of increased equipment cost. [0004] To sum up,...
