Abstract
The invention discloses a heat exchanger and in particular relates to a heat exchanger for exchanging heat with water through heat generated by gas combustion. The heat exchanger comprises a first heat exchange plate, a second heat exchange plate and air blocking pieces between the first heat exchange plate and the second heat exchange plate, wherein the first heat exchange plate and the second heat exchange plate are arranged in a mirror symmetry manner; S-shaped grooves running through the upper ends and the lower ends of the heat exchange plates are formed in the first heat exchange plate and the second heat exchange plate; the flat surfaces of the first heat exchange plate and the second heat exchange plate are fitted with each other and are welded to form a closed S-shaped channel; the air blocking pieces are arranged at the curves of the first heat exchange plate and the second heat exchange plate and adopt arc-shaped structures. According to the heat exchanger disclosed by the invention, pipe materials are replaced with metal plates, and a pipe cutting welding or pipe bending process is replaced with a stamping welding process, so that the heat exchanger has the characteristics of low production cost, high heat exchange efficiency, reliable structure, simplicity for manufacturing and stable quality.
Description
Technical field
The present invention relates to a kind of heat exchanger, relate in particular to a kind of heat exchanger that carries out heat exchange by heat that fuel gas buring produces and water.
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.Fire tube type heat exchanger has two kinds of modes at present: a kind of is that metal straight pipe is cut into some segments, again by end to end being arranged into of some segment metal pipe materials " S " type, finally carry out welding fabrication, this complex manufacturing, difficult quality control and manufacturing cost are high; Another kind is that a strip metal straight tube is directly bent to " S " type by bent tube technique, but owing to being subject to the restriction of production technology characteristic, the bending radius of fire tube is large, and fire tube heat exchange efficiency is low, is difficult to meet user's requirement.
Summary of the invention
The present invention is directed to the high and low deficiency of fire tube heat exchange efficiency of the manufacturing cost of fire tube type heat exchanger in prior art and a kind of heat exchanger is provided, this heat exchanger has that production cost is low, heat exchange efficiency is high, reliable in structure, manufacture is simple and stay-in-grade feature.
Technical scheme of the present invention is as follows:
A kind of heat exchanger comprises the first heat exchanger plates, the second heat exchanger plates and is placed in the windage sheet between two heat exchanger plates; Described the first heat exchanger plates and the second heat exchanger plates are mirror image symmetry, in the first heat exchanger plates and the second heat exchanger plates, there are the upper and lower two ends of heat exchanger plates of perforation and S-type groove, the first heat exchanger plates and the second heat exchanger plates platen surface are fitted and are welded into the S type passage of sealing, the bend place of described windage sheet in First Heat Exchanger and the second heat exchanger, windage sheet is arcuate structure.
The outside punching press of groove of above-mentioned the first heat exchanger plates and the second heat exchanger plates has a plurality of outside projections.
Above-mentioned windage sheet is provided with the blade of stretching out to both sides.
Above-mentioned the 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, with punch welding technique, substitute Pipe Cutting welding or bent tube technique, thereby make that heat exchanger of the present invention has that production cost is low, heat exchange efficiency is high, reliable in structure, manufacture is simple and stay-in-grade feature.

The specific embodiment
For better explanation the present invention, 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, is not intended to limit the present invention.
Heat exchanger as shown in Figures 1 to 3, this heat exchanger comprises the first heat exchanger plates 1, the second heat exchanger plates 2 and is placed in the windage sheet 3 between two heat exchanger plates; Described the first heat exchanger plates 1 and the second heat exchanger plates 2 are mirror image symmetry, and the first heat exchanger plates 1 and the second heat exchanger plates 2 are corrosion-and high-temp-resistant metal material.
In the first heat exchanger plates 1 and the second heat exchanger plates 2, there are the upper and lower two ends of heat exchanger plates of perforation and S-type groove 4, can farthest increase the length of groove 4.The first heat exchanger plates 1 and the second heat exchanger plates 2 platen surface are fitted and are welded into the S type passage of sealing.The outside punching press of groove 4 of the first heat exchanger plates 1 and the second heat exchanger plates 2 has a plurality of outside projections 5, and the effect of projection 5 is can further increase the heat exchange area of groove 4 and high-temperature gas that can flow forms vibration, makes heat exchange more abundant.
The bend place of windage sheet 3 in 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 intert and flow in the both sides of windage sheet 3 along the direction of blade, the effect of windage sheet 3 is that the flowing velocity of high-temperature gas is regulated, and makes heat exchange efficiency reach optimum state.
