Problems solved by technology

This structure is flexible and convenient to use in different installation positions. Its disadvantage is that the thin-walled stainless steel tube is pressed into corrugated sections and requires a lot of materials. The corrugated parts are easy to scale and affect the heat dissipation. high, low produ...

Abstract

The invention discloses a compact component of a planar serpentine coil heat exchange water heater and a manufacturing method thereof. The two ends of the planar serpentine coil with a relatively large spacing between the outer tubes forming the water channel are filled with water and sealed at both ends, and the outer tubes of the water channel are placed in a pair of symmetrical molds with U-shaped arcs. The curved arc mold is pressed and pushed to the length direction of the outer tube of the water channel by the force of the hydraulic prop. The walking of the U curved arc mold is driven by a taper from wide to narrow. The distance between the outer tube of the water channel and the outer tube of the adjacent water channel The distance between them is reduced below the diameter of the outer tube of the water channel, the length of the outer tube of the water channel is lengthened, and the distance between the outer tubes of the water channel is greater than that of the outer tube of the water channel. The shape of the tube is small U-curved arc.

Description

technical field [0001] The invention belongs to the technical field of civil heating, and in particular relates to a heating radiator water heater. Background technique [0002] The Chinese utility model patent "A Scattered Water Exchanger Water Heater with Suppressed Corrugated Continuous Bending" (Patent No. ZL201620779473.0) discloses a pipeline water heater, whose structural form is a common pipe row structure, made of stainless steel, including water channels. The outer pipe and the inner pipe of the water channel are provided with an inner flanging welded wire head seat and a joint seat welded with the ring of the inner pipe of the water channel on the outer pipe of the water channel, and also includes an annular connecting plate and a bracket, which constitute the water channel The components of the outer tube and the inner tube of the water channel include metal tubes, especially suitable for thin-walled stainless steel tubes pressed into corrugated sections, the out...
