Description

Technical Field

[0001] The utility model relates to a high-turbulence wave plate type heat exchange plate, belonging to the field of waste heat recovery heat exchangers. Background Art

[0002] The existing heat exchanger structures in the waste heat recovery field are diverse, but usually mainly tubular heat exchangers and plate heat exchangers are the main ones. The heat exchange plates of the existing plate heat exchangers are mainly bulge support structures, fixed-distance column structures and flat plate structures. Although the existing plate-type structure heat exchange plates can achieve good heat exchange effects, they cannot achieve a good effect in terms of turbulence, which has a certain impact on the heat exchange efficiency. Therefore, a new type of heat exchange plate with higher heat exchange efficiency is proposed. Utility Model Content

[0003] In view of the above deficiencies in the prior art, the problem to be solved by the utility model is to provide a high-turbulence wave plate heat exchanger with a reasonable structural design, which can make the flue gas and air flow in an S-shaped wave-like manner, increase the disturbance effect, make the turbulence effect better, and have a higher heat exchange efficiency.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] The high turbulence wave plate type heat exchange plate comprises a heat exchange plate body, which is provided with bosses and grooves around the heat exchange plate body, the bosses and grooves are staggered and arranged at equal intervals on the heat exchange plate body, the heat exchange plate body inside the bosses and grooves is staggered with square grooves and square bosses, the square grooves are provided with small bosses, and the square bosses are provided with small grooves.

[0006] The high turbulence wave plate heat exchanger plate can form an up-and-down undulating wave channel between the assembled heat exchange plates through the coordination of bosses, grooves, square bosses, square grooves, small bosses and small grooves, so that the flue gas or air flows in an S-shaped wave-like manner, which greatly increases the disturbance effect, makes the turbulence effect better, and improves the heat exchange efficiency. The boss height and the depth of the groove can be flexibly adjusted according to the resistance drop requirements. In addition, only square bosses can be arranged at equal intervals on the heat exchange plate body, small bosses and small grooves are arranged alternately on the square bosses, and small grooves are arranged on the heat exchange plate body between two adjacent square bosses. The length of the square boss is consistent with the width of the heat exchange plate, and the width of the square boss is consistent with the spacing between the square bosses. The square boss and the heat exchange plate body are formed in one piece by stretching. After assembly, a wave channel with up-and-down undulations on one side and a straight channel on the other side can be formed. The structure is simple and reasonable, and it has strong practicality.

[0007] Further preferably, the square grooves and the square bosses are integrally formed with the heat exchange plate body by stretching, and the square grooves and the square bosses are arranged on the heat exchange plate body in a matrix structure.

[0008] Further preferably, the small boss and the small groove are arranged in the middle position of the square groove and the square boss, and are integrally formed with the square groove and the square boss by stretching.

[0009] Further preferably, the boss and the groove are integrally formed with the heat exchange plate body by stretching.

[0010] Further preferably, the connection between the square groove and the square boss and the heat exchange plate body is an arc structure.

[0011] Further preferably, the top surfaces of the bosses and the small bosses are flat plate structures, and the bottom surfaces of the grooves and the small grooves are flat plate structures.

[0012] The beneficial effects of the utility model are:

[0013] The high turbulence wave plate heat exchange plate structure of the utility model is reasonably designed. Through the cooperation of the boss, groove, square boss and square groove on the heat exchange plate, an undulating wave channel is formed. The air or smoke flows in the wave channel to form an S-shaped wave, which produces a good turbulence effect, greatly improves the heat exchange effect and improves the heat exchange efficiency. At the same time, compared with the corrugated plate, rotary heat exchanger and other structures, this structure is more conducive to dust cleaning, not easy to accumulate dust and blockage, and has strong practicality.

[0018] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0019] like Figure 1As shown, the high turbulence wave plate type heat exchange plate described in the utility model includes a heat exchange plate body 1, and bosses 2 and grooves 3 are arranged around the heat exchange plate body 1. The bosses 2 and the grooves 3 are integrally formed with the heat exchange plate body 1 by stretching. The top surface of the boss 2 is a flat plate structure, and the bottom surface of the groove 3 is a flat plate structure. The bosses 2 and the grooves 3 are staggered and arranged at equal intervals on the heat exchange plate body 1. Square grooves 4 and square bosses 5 are staggered on the heat exchange plate body 1 inside the bosses 2 and the grooves 3. Small bosses 6 are arranged on the square grooves 4, and small grooves 7 are arranged on the square bosses 5.

[0020] The square groove 4 and the square boss 5 are integrally formed with the heat exchange plate body 1 by stretching, and the connection between the square groove 4 and the square boss 5 and the heat exchange plate body 1 is an arc structure. The square groove 4 and the square boss 5 are arranged on the heat exchange plate body 1 in a matrix structure. The small boss 6 and the small groove 7 are arranged in the middle of the square groove 4 and the square boss 5, and are integrally formed with the square groove 4 and the square boss 5 by stretching. The top surface of the small boss 6 is a flat plate structure, and the bottom surface of the small groove 7 is a flat plate structure.

[0021] The working principle and use process of this utility model:

[0022] like Figure 2-Figure 3 As shown, when in use, multiple heat exchange plates are placed upside down for assembly, and two heat exchange plates form a plate pair. The flue gas flowing in the flow channel between the plate pairs flows in an S-shaped wave shape during the flow process; another flow channel is formed between the plate pairs, and the air flows in the flow channel in an S-shaped wave shape. Among them, the flow channel between the heat exchange plates is supported by the cooperation of the bosses 2 or grooves 3 of the two adjacent heat exchange plates, and the cooperation of the square grooves 4 and the square bosses 5 forms a wave channel that fluctuates up and down between the two adjacent heat exchange plates. The flue gas or air can flow in an S-shaped wave in the wavy channel between the heat exchange plates, which greatly increases the disturbance effect, makes the turbulence effect better, and the heat exchange efficiency higher.

[0023] The present invention is not limited to the above-mentioned specific implementation modes. Changes, modifications, additions or substitutions made by ordinary technicians in this field within the essential scope of the present invention should also fall within the protection scope of the present invention.
