Deep hole type water cooling loop device for baseplate of electric cabinet

Abstract

The invention provides a deep hole type water cooling loop device for a baseplate of an electric cabinet, and aims at solving the problem that an existing water cooling loop on the baseplate of the electric cabinet of a coal mining machine has the defects of large cutting output of metal and long processing time. The key points of the device are as follows: a plurality of rows of deep holes are drilled on the thickness of the baseplate, the axial line of the deep holes is parallel to the surface of the baseplate, pin plugs are welded at orifices of the deep holes for sealing, a communicating waterway is formed between adjacent two rows of the deep holes for communicating the adjacent two rows of the deep holes, as for the adjacent communicating waterways, one is arranged at the upper ends of the deep holes, and the other one is arranged at the lower ends of the deep holes, thereby connecting all cooling main waterways into a pulse wave-shaped cooling waterway. The device has the advantages of greatly reducing the welding quantity in using steel plates for sealing the waterways and the cutting output of metal.

Description

technical field [0001] The invention relates to a water cooling circuit device on the bottom plate of an electric control box of a coal mining machine. Background technique [0002] The water cooling circuit on the bottom plate of the electric control box of the existing coal mining machine is milled by T-shaped rectangular slots. The upper part of the slots is welded and sealed with steel plates, and a rectangular hole is left in the middle to form a water system circuit. The disadvantages of this technology are that first, the amount of metal cutting is large and the processing time is long; second, the entire circuit of the rectangular groove needs to be welded with steel plates to seal the water to form a water circuit. The welding volume is large, and the pressure test cannot be guaranteed after welding. Many, which greatly affect the production cycle and cost of the electric control box; the third is that the rectangular groove involves a large amount of welding, and t...

Problems solved by technology

The disadvantages of this technology are that first, the amount of metal cutting is large and the processing time is long; second, the entire circuit of the rectangular groove needs to be welded with steel plates to seal the water to form a water circuit. The welding volume is large, and the pressure test cannot be guaranteed after welding. Many, which greatly affect the production cycle and cost of the electric control box; the third is that the rectangular groove involves a large amount of welding, and the bottom plate is subjected to huge welding stress when welding, so it is necessary to increase the stress relief process, increase the production process and cost, and affect the electric control box.
