Abstract
This utility model relates to a rapid cooler for coal mining machines using a pipe-type cooling system, comprising: multiple parallel U-shaped pipes, a main inlet pipe connecting the inlets of the multiple U-shaped pipes, a main inlet pipe connecting the outlets of the multiple U-shaped pipes, and a flange seat for fixing the main inlet pipe and the main inlet pipe. The inlets of the multiple U-shaped pipes are welded and fixed to the inlet ends of the main inlet pipe, and the outlets of the multiple U-shaped pipes are welded and fixed to the inlet ends of the main outlet pipe. The welding and fixing positions are all located outside the fixed end of the flange seat. The advantages of this utility model are: using multiple independent U-shaped pipes as circulation pipes reduces the resistance to cooling water flow, significantly improves the cooling speed, greatly reduces the difficulty of processing and manufacturing, and completely eliminates leakage problems.
