Abstract
The utility model provided a high pressure resistance copper pipe fin type heat exchanger which is composed of a left tube plate (1), a right tube plate (2), a U-shaped copper pipe (3), a fin (4), and a bend (5). At the connection position of the U-shaped copper pipe (3) and the bend (5), the bend (5) is inserted into the expansion joint of the U-shaped copper pipe (3) which is subjected to the machining manner of the combination of the expansion of the pipe mouth and the conical expansion of the pipe mouth to complete the welding, thereby effectively guaranteeing the permeation of scolder and the pressure resistance of the heat exchanger. The heat exchanger in the utility model provides technical assurance for the development and application of a forced ventilation copper pipe fin type heat exchanger.
Description
Technical field
The utility model profit relates to copper tube and fin formula field of heat exchangers, and the utility model is high pressure resistant copper tube and fin formula heat exchanger.
Background technology
Energy field, forced ventilation copper tube and fin formula heat exchanger is as a kind of conventional heat exchanger, owing to its version has simply obtained using widely.But its conventional structure form and Type of Welding are difficult to satisfy it and under the mesohigh situation, move, and our the high pressure resistant copper tube and fin formula of novel practical patent heat exchanger also just arises at the historic moment.
Summary of the invention
Goal of the invention: be to be the expansion application of the forced ventilation copper tube and fin formula heat exchanger of future market, the application under the mesohigh situation provides effective guarantee.
Technical scheme: the high pressure resistant copper tube and fin formula of the utility model heat exchanger, its chief component has left tube sheet, right tube sheet, U type copper pipe, fin, elbow.
During production and processing; U type copper pipe passes left tube sheet, fin and right tube sheet, carries out the expanded joint of copper pipe and fin and tube sheet after passing, the processing of the laggard administration-management mouth of expanded joint connected mode; Carry out the welding of elbow and copper pipe after the processing, thereby accomplish the processing of copper tube and fin formula heat exchanger.The connected mode of traditional elbow and U type copper pipe has: card edge type, the mouth of pipe swell, and insert the back, the mouth of pipe inserts after being expanded into taper, but these connected modes are difficult to satisfy the operation of copper tube and fin formula heat exchanger under the mesohigh operating mode.The high pressure resistant copper tube and fin formula of our utility model heat exchanger being connected of U type copper pipe and elbow adopts the mouth of pipe to swell and is expanded into the mode that taper combines with the mouth of pipe, can effectively guarantee infiltration and heat exchanger withstand voltage of scolder like this.
The utility model advantage: high pressure resistant copper tube and fin formula heat exchanger; Through choose reasonable to the copper pipe wall thickness; U type copper pipe is connected with the reasonable of elbow, effectively guarantees the high pressure resistant of copper tube and fin formula heat exchanger, thereby reaches benefits such as enlarging copper tube and fin formula heat exchanger applications scope.The utility model has certain versatility under copper tube and fin formula heat exchanger mesohigh operating mode.

The specific embodiment
As shown in the figure, the high pressure resistant copper tube and fin formula of the utility model heat exchanger is applied to copper tube and fin formula field of heat exchangers, and its chief component has left tube sheet 1, right tube sheet 2, U type copper pipe 3, fin 4, elbow 5.
Described U type copper pipe, elbow all adopt the thickening type copper pipe, in the position that U type copper pipe is connected with elbow, U type copper pipe are processed into the form that bowl adds the mouth that expands of turning over, and elbow are inserted in the bloated mouth of U type copper pipe, accomplish welding.
Claims (1)
