Abstract

The utility model discloses a five-pipe heat exchanger, which comprises copper pipes, heat absorbing fins, an outer separation blade and an inner separation blade, wherein the heat absorbing fins and the copper pipes are fixed by welding. The five-pipe heat exchanger is characterized in that: the copper pipes are arranged in the form of five pipes; the joint of each copper pipe has a U-shaped structure; the radiating fins are copper fins; and the outer separation blade and the inner separation blade are welded at the two ends of the heat absorbing fins. The copper pipes are arranged in the form of five pipes, and the joints have U-shaped structures, so that an S-shaped water channel is formed; the five-pipe heat exchanger has a simple structure, and is convenient to install; and the five-pipe heat exchanger is formed by gang welding of the copper pipes and the copper fins, and is made of red copper, so that the welding is good, and the heat exchange efficiency can be effectively improved.

Description

A kind of five pipe in pipes

Technical field

The utility model relates to a kind of device relevant with gas burner and is specifically related to a kind of five pipe in pipes.

Background technology

In the heat exchanger of using morely in the market as can be known, adopt single file to be arranged in parallel between the pipeline according to investigations, wherein pipeline is used pipe more.This patent adopts elliptical tube to wear copper fin, and elliptical tube has bigger sectional area than pipe under same flow, increased the heat-absorbent surface of pipeline.So the utility model provides a kind of five pipe in pipes at this, solve the heat exchanger effectiveness problem.

The utility model content

Technical problem to be solved in the utility model is how a kind of five pipe in pipes are provided, and solves above-mentioned the problems of the prior art.

The technical problem that the utility model proposed is to solve like this: construct a kind of five pipe in pipes, integral body comprises that welding is fixing between copper pipe and heat absorption described heat absorption fin of fin and the copper pipe, it is characterized in that: described copper pipe is scattered in five pipes, be respectively first copper pipe, second copper pipe, the 3rd copper pipe, the 4th copper pipe and the 5th copper pipe, wherein corresponding respectively water inlet or the delivery port copper pipe of forming of an end of first copper pipe and the 5th copper pipe connects part and constitutes the U-shaped structure, described radiating fin is a copper fin, wherein also comprise the outer catch and the interior catch that are welded on the radiating fin two ends, wherein the other end of first copper pipe connects second copper pipe by the U-shaped structure at equidirectional place, second copper pipe connects three copper pipe by the U-shaped structure at equidirectional place by the other end, the 3rd copper pipe connects four copper pipe by the U-shaped structure at equidirectional place by the other end, and the 4th copper pipe connects the 5th copper pipe by the other end by the U-shaped structure at equidirectional place makes its whole serpentine water route that forms.

The beneficial effects of the utility model are: copper pipe are scattered in five tubuloses, connect part and constitute the U-shaped structure, and simple in structure, to be convenient to install, this device adopts copper pipe and copper fin Combination Welding to form, and copper pipe is oval, and material is identical effectively to improve heat exchanger effectiveness.
