A circular copper water pipe heated by combustion of a water heater and its manufacturing method

Abstract

The invention discloses a circular copper water pipe heated by combustion of a water heater. The circular copper water pipe (1) is drilled with a plurality of upper round holes (11) and lower round holes (12) corresponding to the vertical direction, and the upper round holes The diameter of (11) is less than the diameter of lower circular hole (12), on upper circular hole (11) and lower circular hole (12), be fixed with the copper funnel cup (13) of conical upside-down installation simultaneously, copper funnel cup (13) The cone is fixed on the wall of the upper round hole (11), and the foot is fixed on the wall of the lower round hole (12); this product is mainly used to block the water flow velocity, increase the combustion area, improve thermal efficiency, and save gas.

Description

Technical field [0001] The invention relates to a water pipe heated by combustion of a water heater, in particular to a round copper water pipe heated by the combustion of a water heater and a manufacturing method thereof. Background technique [0002] Existing water heaters’ combustion and heating water pipes are all hollow direct-flow pipes. The direct-flow pipes are bent into pipe rows, and a number of fire radiators are arranged below the pipe rows. The fire power knob, water temperature knob, and summer / winter adjustment knob are used to adjust the firepower to control the water temperature. Since the fire row is burning, it can only burn on the outer wall of the tube row. For the combustion of several tube rows, only the burning quantity of the fire row can be adjusted or the fire power can be increased or decreased to adjust the water temperature. The consumption of gas increases accordingly; because it is a straight-through pipe, the water flow speed is relatively fast, a...

AI Technical Summary

Problems solved by technology

[0002] The water pipes heated by the combustion of the existing water heaters are all hollow direct-current pipes. The direct-current pipes are bent into pipe rows, and a number of fire rows are arranged under the pipe rows. The firepower is adjusted through the firepower knob, the water temperature knob, and the summer and winter adjustment knobs to control the water temperature. When the fire row burns, it can only burn the outer wall of the tube row, and the combustion of several tube rows can only adjust the burning quantity of the fire row or increase or decrease the firepower to adjust the temperature of the water. The number of fire row combustion increases and the firepower increases. The gas consumption increases accordingly; since it is a direct-flow pipe, the water flow speed is relatively fast, so the water can only take more detours by increasing the number of rows of pipes and increasing the number of rows of pipes by increasing the fire to obtain high-temperature water; The above-mentioned old-style products generally have three rows of fire rows, a large number of pipe rows, and high gas consumption when high-temperature water is needed.
