Heater multi-pipe heat conducting type shell-tube water storage bearing heat interchanger and manufacturing technology thereof

Abstract

The invention provides a heater multi-pipe heat conducting type shell-tube water storage bearing heat interchanger and a manufacturing technology thereof. The heat interchanger comprises multiple round cold water pipes; head external blocking plates are welded at two ends of the round cold water pipes; heater pipe connecting blocking plates are welded in pipe openings at two ends of the round cold water pipes; round heater pipe connecting openings are formed on the heating pipe connecting blocking plates; pipe cavities are directly welded and communicated by the adjacent round cold water pipes through straight round cold water communicating pipes or butt-welded wall pulling pipes; at least one round heater pipe is penetrated into the cavity of each round cold water pipe; pipe openings of two ends of each round heater pipe are in welded connection with connecting openings of the round heater pipe on the heater pipe connecting blocking plates; round heater communicating pipes are in welded communication with the heater pipe connecting blocking plates or the round heater communicating pipes are sequentially welded and communicated with the head external blocking plates and are communicated with a thermal fluid shunting cavity to form a thermal fluid circulated heat transmission passage. The heat interchanging structure is more scientific and reasonable; the heat transmission area is improved by 55%-100%; the heat conduction rate is accelerated; the heat exchanging effect is excellent. The welding joints of the communicating pipes among the cavities are difficultly subjected to water leakage.

Problems solved by technology

More importantly, the heat in the center of the heating tube is not easily absorbed by the cold fluid, so the heat transfer effect is poor

The above-mentioned prior art has the technical defects of small heat transfer area, low effective utilization rate of heat, poor heat transfer effect and water leakage from the welding seam of the connecting pipe.
