Abstract

The invention relates to variable frequency controller cooling technology, in particular to a variable frequency controller cooling device for a shutter vehicle used for a coal mine, which is used for effectively cooling the heat produced by a variable frequency controller. The device is provided with a circulating power system, a water tank, and a circulating water channel, the water tank is connected to the circulating water channel of cooling water via a circulating motor of the circulating power system through a pipeline, and the circulating water channel is placed on the bottom of the variable frequency controller. The device takes away the heat produced by the variable frequency controller through the circulating water channel of the cooling water arranged on the bottom of the variable frequency controller, drives a circulating water hydraulic motor to ensure that the cooling water finishes the circulation by means of the power produced by the running driving of a vehicle body, drives a fan through a fan hydraulic motor to make the fan cool a circulating water heat exchanger, stores the cooling water through a cooling water tank, and utilizes the surface of the cooling water tank to assist in heat dissipation. The device can solve the problems such as effective cooling of the variable frequency controller and so on, effectively control the working temperature rise of the variable frequency controller, and ensure that the variable frequency controller normally works within the specified temperature range.

Description

technical field [0001] The invention relates to a frequency conversion controller cooling technology, in particular to a frequency conversion controller cooling device for a shuttle car used in coal mines, which is a device for effectively cooling the heat generated by the frequency conversion controller. Background technique [0002] At present, the new mining shuttle car is driven by a switched reluctance motor, and the frequency conversion controller used in the switched reluctance motor has strict temperature requirements. If the temperature exceeds the required standard, it cannot work normally. Therefore, its effective cooling is very important, and the space of the vehicle is limited, so the cooling system must be compact in structure and reasonably arranged under the premise of ensuring the cooling effect. Contents of the invention [0003] The object of the present invention is to provide a cooling device for a frequency conversion controller, which solves the pro...
