Heat exchange device

Abstract

The invention provides a heat exchange device, and relates to the field of thermal energy exchange and utilization of industrial waste water. The heat exchange device comprises heat exchange tubes, ashell and fixing disks; the fixing disks are in a plate shape and provided with a plurality of through holes connected with the heat exchange tubes, diameters of the through holes are the same, exceptthe through holes being at the edges of the fixing disks, six through hole bodies are evenly distributed on the periphery of each through hole, connection of the centers of every six through hole bodies forms a regular hexagon, and the center of the through hole surrounded by the corresponding six through holes coincides with the center of the corresponding regular hexagon; the edges of the fixing disks are welded to the inner wall of the shell; and the heat exchange tubes are welded between the two fixing disks and perpendicular to the fixing disks. According to the heat exchange device, theheat exchange tubes are regularly arranged, and the heat exchange area is large, so that heat exchange can be more fully performed.

Description

technical field [0001] The invention relates to the field of heat energy exchange and utilization of industrial waste water, in particular to a heat exchange device. Background technique [0002] At present, the commonly used method of heat exchange and utilization of industrial machine cooling water is to set grilles in the pipeline to make cold and hot water alternately flow in the pipeline, so that the cold water can take away heat energy, and the industrial machine cooling water loses heat energy and then puts it into the machine cooling cycle system. Since the hot and cold water are separated by grille, the heat exchange area is limited and the exchange effect is not good. Contents of the invention [0003] The purpose of the present invention is to solve the problem of limited heat exchange area and poor exchange effect of the currently used industrial machine cooling water heat energy exchange and utilization method, and provides a heat exchange device, the heat exc...
