The heat exchange sheet 110 has a larger heat exchange area, so that the heat exchange efficiency can be effectively improved. At the same time, the high temperature flue gas in each flue gas passage 112 is replaced by the heat exchange sheet 110 and the heat exchange tube adjacent to the heat exchange sheet 110. Enclosed by 200, the heat exchange sheet 110 and the corresponding heat exchange tube 200 are sufficiently contacted in the flue gas passage to further improve the heat exchange efficiency; at the same time, the high temperature flue gas is dispersed and deflected through the plurality of flue gas passages 112, Guide the flow of high-temperature flue gas, which can make the high-temperature flue gas flow evenly from Make more uniform heat transfer, better heat transfer.
所述换热片110的材质可以是铜、铝等导热性能较好的金属，也可以是耐腐蚀性能比较好的不锈钢，由于本发明的换热件100的换热效率高，因此使用导热性能一般的不锈钢制得，也可达到较好的换热效果。The heat exchange sheet 110 may be made of a metal having good thermal conductivity such as copper or aluminum, or may be a stainless steel having good corrosion resistance. Since the heat exchange element 100 of the present invention has high heat exchange efficiency, thermal conductivity is used. Generally made of stainless steel, it can also achieve better heat transfer.
高温烟气在烟气过道112内沿烟气过道112的延伸方向流动，烟气过道112的形状决定高温烟气的流向，烟气过道112的形状可以根据需要进行设置；例如，所述烟气过道112在其延伸方向上呈直线型设置、波浪型设置或折线型设置。综合烟气过道112的阻力和换热效果考虑，可调整通道的形状和同一侧的表面相邻两个***部111之间间距，如阻力较大，则可设置烟气过道112为直线型，同时加大相邻两个***部111之间间距；如换热效率要求较高，则减小相邻两个***部111之间间距，设置烟气过道112为波浪型或折线型；同时还可以通过调节烟气过道112与高温烟气的进气方向（如虚线箭头所示）之间的角度，调整高温烟气在烟气过道112中流动的阻力，例如，高温烟气的进气方向与烟气过道112的延伸方向的夹角越大，则阻力越大；其中直线型设置时，容易制备，呈波浪型或折线型设置时，可以增加高温烟气在烟气过道112中的总行程，从而增加换热时间，提高换热效果；请参阅图3和图4，在本实施例中，考虑制备的难易程度，该烟气过道112在其延伸方向上呈直线型设置。The high temperature flue gas flows in the flue gas passage 112 along the extending direction of the flue gas passage 112. The shape of the flue gas passage 112 determines the flow direction of the high temperature flue gas. The shape of the flue gas passage 112 can be set as needed; for example, the flue gas The aisle 112 is arranged in a straight line, a wave type or a line type in its extending direction. Considering the resistance and heat exchange effect of the integrated flue gas passage 112, the shape of the passage and the distance between the two ridges 111 adjacent to the surface on the same side can be adjusted. If the resistance is large, the flue gas passage 112 can be set to be straight. At the same time, the spacing between the adjacent two ridges 111 is increased; if the heat exchange efficiency is higher, the spacing between the adjacent two ridges 111 is reduced, and the flue gas passage 112 is set to be a wave or a broken line; The resistance of the high temperature flue gas flowing in the flue gas passage 112 can be adjusted by adjusting the angle between the flue gas passage 112 and the intake direction of the high temperature flue gas (as indicated by the dotted arrow), for example, the intake direction of the high temperature flue gas. The larger the angle with the extending direction of the flue gas passage 112, the greater the resistance; wherein the linear type is easy to prepare, and when the wave type or the broken line type is set, the total amount of the high temperature flue gas in the flue gas passage 112 can be increased. The stroke, thereby increasing the heat exchange time, and improving the heat exchange effect; referring to FIG. 3 and FIG. 4, in the present embodiment, considering the ease of preparation, the flue gas passage 112 is linearly disposed in the extending direction thereof.
由于本发明的换热件100与换热管200邻接，为了两者安装时更牢固和平稳，优选地，所述***部111设有用以与所述换热管200贴靠的安装平面，换热件100与换热管200邻接时，安装平面贴靠换热管200的外壁，接触面积较大，导热效果好且安装可靠性较高，同时，与换热件100装配的换热管200连接面也应该是平整面，使换热管200和换热件100的连接更为方便、牢固。Since the heat exchange member 100 of the present invention is adjacent to the heat exchange tube 200, in order to be more firm and stable during installation, preferably, the ridge portion 111 is provided with a mounting plane for abutting against the heat exchange tube 200, When the heat member 100 is adjacent to the heat exchange tube 200, the mounting plane abuts against the outer wall of the heat exchange tube 200, the contact area is large, the heat conduction effect is good, and the installation reliability is high, and at the same time, the heat exchange tube 200 assembled with the heat exchange member 100 The connecting surface should also be a flat surface, which makes the connection between the heat exchange tube 200 and the heat exchange member 100 more convenient and firm.
换热件100可以只包括一片换热片110，也可以包括多个换热片110，其中，只包括一片换热片110时，所述换热件100的烟气通道是由一个换热片110的烟气过道112直接构成；请参阅图1和图2，在本实施例中，优选地，所述换热件100包括多个换热片110，多个所述换热片110依次拼接，且多个所述换热片110的烟气过道112连通形成所述过烟气通道。设置多个换热片110，多个换热片110的烟气过道112拼接形成的烟气通道，因而可以在每一个换热片110的烟气过道112的延伸方向和形状较为简单的前提下，通过对多个换热片110的烟气过道112的延伸方向和形状的灵活设置，改变拼接形成的烟气通道的延伸方向和形状；从而适应换热件100的换热需求。The heat exchange member 100 may include only one heat exchange sheet 110, and may also include a plurality of heat exchange sheets 110. When only one heat exchange sheet 110 is included, the flue gas passage of the heat exchange member 100 is composed of a heat exchange sheet. The flue gas passage 112 of 110 is directly formed; referring to FIG. 1 and FIG. 2, in the embodiment, preferably, the heat exchange member 100 includes a plurality of heat exchange sheets 110, and the plurality of heat exchange sheets 110 are sequentially spliced. And a plurality of the flue gas passages 112 of the heat exchange sheet 110 are connected to form the over-smoke passage. A plurality of heat exchange fins 110 are disposed, and the flue gas passages formed by the flue gas passages 112 of the plurality of heat exchange fins 110 are spliced, so that the extending direction and shape of the flue gas passages 112 of each of the heat exchange fins 110 are relatively simple. By flexibly setting the extending direction and shape of the flue gas passages 112 of the plurality of heat exchange fins 110, the extending direction and shape of the flue gas passage formed by the splicing are changed; thereby adapting to the heat exchange requirement of the heat exchange member 100.
为了增加高温烟气在烟气通道内的行程，请参阅图1，在本实施例中，优选地，所述烟气通道呈弯曲或弯折设置。其中，烟气通道的弯曲或弯折设置，可以通过调节不同的换热片110的烟气过道112的延伸方向来实现，例如可以设置相邻两个烟气过道112的延伸方向呈不为0°的夹角；烟气通道的弯曲或弯折设置，还可以通过调节不同的换热片110的烟气过道112的形状来实现，例如换热片110的烟气过道112呈弯曲或弯折设置。高温烟气在弯曲或弯折的烟气通道内流动，高温烟气的行程更长，同时高温烟气受到的阻力增大，流速减慢，因而高温烟气与换热片110的换热时间更长、换热面积更大，因此能够有效提高换热效率。In order to increase the stroke of the high temperature flue gas in the flue gas passage, referring to FIG. 1, in the present embodiment, preferably, the flue gas passage is curved or bent. The bending or bending arrangement of the flue gas passage can be realized by adjusting the extending direction of the flue gas passage 112 of the different heat exchange fins 110. For example, the extending direction of the adjacent two flue gas passages 112 can be set to be 0. The angle of °; the bending or bending of the flue gas passage can also be achieved by adjusting the shape of the flue gas passage 112 of the different heat exchange fins 110, for example, the flue gas passage 112 of the heat exchange fins 110 is bent or bent.

That is, the extending direction of the adjacent two flue gas passages 112 is not at an angle of 0°. At this time, the flue gas passage is bent at the junction of the two flue gas passages 112, and the high-temperature flue gas is bent in the flue gas. The flow in the channel has a longer stroke, and the resistance of the high-temperature flue gas is increased, and the flow rate is slowed down, so that the heat exchange time of the high-temperature flue gas and the heat exchange sheet 110 is longer and the heat exchange area is larger, so that the exchange can be effectively improved.

The angle between the extending direction of the flue gas passages 112 of the adjacent two heat exchange sheets 110 is an obtuse angle, and the flue gas passages 112 on the surfaces of the two adjacent heat exchange sheets 110 are butted; The forming of the sheet 110 is difficult, and the total length of the flue gas passage is long, which reduces the production difficulty while ensuring the heat exchange effect. The number of heat exchange sheets 110 in the heat exchange member 100 can be selected according to actual conditions. In the present embodiment, the heat exchange member 100 includes four heat exchange sheets 110, and the four heat exchange sheets 110 are sequentially spliced in the intake direction.

Through the transfer of the heat exchange tube 200 and the heat exchange member 100, the high-temperature flue gas is used to heat the water to realize the heat exchange function.
可以根据换热器的换热效率，设置换热件100的换热片110的数量及每个换热片110上的烟气过道112的形状和延伸方向；例如，在换热效率要求低的时候，可以设置较少的换热片110和换热管200，每个换热片110的烟气过道112的形状为直线型、且烟气过道112的延伸方向与进气方向平行，从而减少换热器的体积和重量；又例如，在换热效率要求高的时候，可以设置较多的换热片110和换热管200，每个换热片110的烟气过道112的形状为波浪型或折线型、且烟气过道112的延伸方向与进气方向呈不为0°的夹角。通过换热件100和换热管200的合理设置，可使得使用该换热器的燃气热水器，无需增加冷凝热量收集的二次热交换器，也可达到冷凝式热交换器的换热效率，有利于节约能源，节约材料成本，减少工序。The number of the heat exchange fins 110 of the heat exchange member 100 and the shape and extension direction of the flue gas passage 112 on each heat exchange fin 110 may be set according to the heat exchange efficiency of the heat exchanger; for example, the heat transfer efficiency is low.
