Abstract
The present invention discloses a kind of heat exchanger, particularly by fuel gas buring produce the heat exchanger that heat and water carry out heat exchange.The windage sheet that this heat exchanger comprises the first heat exchanger plates, the second heat exchanger plates and is placed between two heat exchanger plates; Described first heat exchanger plates and the second heat exchanger plates are specular, the upper and lower two ends of through heat exchanger plates are had and S-type groove in first heat exchanger plates and the second heat exchanger plates, first heat exchanger plates and the second heat exchanger plates platen surface are fitted and are welded into closed S type passage, described windage sheet is in the bend place of First Heat Exchanger and the second heat exchanger, and windage sheet is arcuate structure.Heat exchanger of the present invention substitutes tubing with sheet metal, substitutes Pipe Cutting welding or bent tube technique with punch welding technique, thus heat exchanger of the present invention is had, and production cost is low, heat exchange efficiency is high, structure is reliable, manufacture simple and stay-in-grade feature.
Description
Technical field
The present invention relates to a kind of heat exchanger, particularly relate to a kind of by fuel gas buring produce the heat exchanger that heat and water carry out heat exchange.
Background technology
Traditional gas water heater, combustion gas boiled water machine and gas steam generator generally adopt fire tube type heat exchanger to carry out heat exchange.Current fire tube type heat exchanger has two kinds of modes: one is that metal straight pipe is cut into some segments, " S " type is arranged into again by end to end for some segment metal pipe materials, finally carry out welding fabrication, this complex manufacturing, difficult quality control and manufacturing cost high; Another kind is that a strip metal straight tube is directly bent to " S " type by bent tube technique, but due to the restriction by production technology characteristic, the bending radius of fire tube is large, and fire tube heat exchange efficiency is low, is difficult to the requirement meeting user.
Summary of the invention
The present invention is directed to the deficiency that manufacturing cost is high and fire tube heat exchange efficiency is low of fire tube type heat exchanger in prior art and provide a kind of heat exchanger, this heat exchanger has that production cost is low, heat exchange efficiency is high, structure is reliable, manufacture simple and stay-in-grade feature.
Technical scheme of the present invention is as follows:
The windage sheet that a kind of heat exchanger comprises the first heat exchanger plates, the second heat exchanger plates and is placed between two heat exchanger plates; Described first heat exchanger plates and the second heat exchanger plates are specular, the upper and lower two ends of through heat exchanger plates are had and S-type groove in first heat exchanger plates and the second heat exchanger plates, first heat exchanger plates and the second heat exchanger plates platen surface are fitted and are welded into closed S type passage, described windage sheet is in the bend place of First Heat Exchanger and the second heat exchanger, windage sheet is arcuate structure, and described windage sheet is provided with the blade of stretching out to both sides.
The outside punching press of groove of above-mentioned first heat exchanger plates and the second heat exchanger plates has multiple outside projection.
Above-mentioned first heat exchanger plates and the second heat exchanger plates are corrosion-and high-temp-resistant metal material.
Beneficial effect of the present invention: heat exchanger of the present invention substitutes tubing with sheet metal, substitute Pipe Cutting welding or bent tube technique with punch welding technique, thus heat exchanger of the present invention is had, and production cost is low, heat exchange efficiency is high, structure is reliable, manufacture simple and stay-in-grade feature.
Accompanying drawing explanation
Fig. 1 is heat exchanger overall structure figure of the present invention;
Fig. 2 is heat exchanger structure exploded view of the present invention;
Fig. 3 is windage chip architecture figure of the present invention.
Detailed description of the invention
In order to better the present invention is described, existing in conjunction with the embodiments and accompanying drawing be further described.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Heat exchanger as shown in Figures 1 to 3, the windage sheet 3 that this heat exchanger comprises the first heat exchanger plates 1, second heat exchanger plates 2 and is placed between two heat exchanger plates; Described first heat exchanger plates 1 and the second heat exchanger plates 2 are in specular, and the first heat exchanger plates 1 and the second heat exchanger plates 2 are corrosion-and high-temp-resistant metal material.
There are the upper and lower two ends of through heat exchanger plates and S-type groove 4 in first heat exchanger plates 1 and the second heat exchanger plates 2, farthest can increase the length of groove 4.First heat exchanger plates 1 and the second heat exchanger plates 2 platen surface are fitted and are welded into closed S type passage.The outside punching press of groove 4 of the first heat exchanger plates 1 and the second heat exchanger plates 2 has multiple outside projection 5, the effect of projection 5 be can increase further groove 4 heat exchange area and can to flowing high-temperature gas formed vibration, make heat exchange more abundant.
Windage sheet 3 is in the bend place of First Heat Exchanger 1 and the second heat exchanger 2, windage sheet 3 is arcuate structure, windage sheet 3 is provided with the blade 6 of stretching out to both sides, blade 6 can make air-flow interspersed flowing in the both sides of windage sheet 3 along the direction of blade, the effect of windage sheet 3 regulates the flowing velocity of high-temperature gas, makes heat exchange efficiency reach optimum state.
Claims (3)
1. a heat exchanger, is characterized in that: the windage sheet that this heat exchanger comprises the first heat exchanger plates, the second heat exchanger plates and is placed between two heat exchanger plates; Described first heat exchanger plates and the second heat exchanger plates are specular, the upper and lower two ends of through heat exchanger plates are had and S-type groove in first heat exchanger plates and the second heat exchanger plates, first heat exchanger plates and the second heat exchanger plates platen surface are fitted and are welded into closed S type passage, described windage sheet is in the bend place of First Heat Exchanger and the second heat exchanger, windage sheet is arcuate structure, and described windage sheet is provided with the blade of stretching out to both sides.
