Abstract
The utility model relates to a dual-channel heat exchanger of a wall-hanging boiler, which is relevant to a heating heat exchange device. The utility model solves the problems of poor standard performance, short service life and low heat exchange efficiency of a heat collection sheet. A water inlet pipe joint and a water outlet pipe joint (1 and 10) which are connected with an inner pipe (9) are arranged at both ends of a first water tank (2); a second water tank (7) and a third water tank (11) are respectively provided with a water inlet pipe joint (8) and a water outlet pipe joint (8); a plurality of outer pipes (5) are connected between the first water tank (2) and the second water tank and the third water tank box (7 and 11); the inner pipe (9) is positioned in the outer pipe (5); the inner pipe (9) extending out of the adjacent end of the water tank is connected with a connection pipe (13); the heat collection sheet (4) is arranged on the outer pipes (5) on which a left baffle plate (3) and a right baffle plate (6) are arranged; the heat collection sheet (4) is positioned between the left baffle plate (3) and the right baffle plate (6). The utility model is mainly used for heat exchangers of a gas stove.
Description
Technical field:
The utility model is relevant with the heat exchanger of heating system.
Background technology:
Existing wall hanging furnace heat exchanger is equipped with tens of heat collecting sheets on outer tube, because heat collecting sheet is thinner, heat collecting sheet is easy to stressed and is out of shape, and reduces heat exchange efficiency and service life.Because do not locate benchmark on the outer tube, the installation of heat collecting sheet is lack of standardization, assembling is inconvenient.Interior pipe cross section is that abnormity is oval, and pipe can't weld fully with the outer tube junction in the special-shaped ellipse, and heat exchange efficiency is poor.
The content of utility model:
The purpose of this utility model provides a kind of long service life, is convenient to the binary channels wall hanging furnace heat exchanger that heat exchange efficiency is high is installed.
The utility model is achieved in that
The utility model binary channels wall hanging furnace heat exchanger, there is the water-in and water-out pipe joint 1 that is connected with interior pipe 9 at the two ends of the first water box 2,10, the second water box 7, the 3rd water box 11 has admitting pipe joint 8 and titting water outlet 12 respectively, some outer tubes 5 are connected in first water box 2 and second and third water box 7, between 11, interior pipe 9 is positioned at outer tube 5, the abutting ends that interior pipe 9 stretches out the water box connect by tube connector 13, heat collecting sheet 4 is contained on the outer tube 5, and right baffle-plate 3 and right baffle plate 6 are housed on the outer tube 5, and heat collecting sheet 4 is between right baffle-plate 3 and right baffle plate 6.
The cross section of outer tube 5 is oval, and the cross section of interior pipe 9 is a cross, and the cross top of interior pipe 9 is fluted 15, and welding bar 14 is arranged in the groove 15.
The utility model provides a kind of novel interior pipe, binary channels wall hanging furnace heat exchanger that heat exchange efficiency is higher of containing.Have catch to separate between water box and the heat collecting sheet, because of heat collecting sheet is thinner, the catch at two ends can play the effect of protection heat collecting sheet, prolongs the service life of interchanger, and catch can be used as the location benchmark when installing, and makes things convenient for the installation of heat exchanger.
Interior pipe adopts pipe in the novel cross, and interior pipe tip designs is fluted, in order to deposit welding rod, when soldering, because the capillarity of liquid, the welding fluid of fusing closely welds together groove top and outer tube, solve the problem that the inner and outer pipe contact point can't weld fully, improved heat exchange efficiency.
Description of drawings:
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment:
Binary channels of the present utility model is interior pipe and outer tube passage.Interior pipe 9 is contained in outer tube 5 inside.Outer tube 5 absorbs the heat that the imflammable gas burning produces with the heat collecting sheet 4 that is connected thereon, make from water box 7,2 and enter cold water heating in the outer tube, temperature rises, temperature reaches 60～90 ℃ hot water and enters pipeline through water box 11 from outlet pipe 12 and connect interior radiator for heating, and water inlet pipe 8 is arranged on the water box 7.Water in the interior pipe 9 are heated by the heat exchange of the tube wall of hot water in inner tubal wall and the outer tube 5 and outer tube 5, and life hot water being provided.Outer tube 5 is connected between water box 2 and the water box 7,11, and interior pipe 9 is positioned at outer tube 5, and the abutting end that interior pipe 9 stretches out the water box connects by tube connector 13.Right baffle-plate 3 and right baffle plate 6 are housed on the outer tube 5.Heat collecting sheet 4 is positioned at a left side, between the right baffle plate.
