[0003] The patent with the publication number CN 215278355 U discloses a heat exchanger for a coater. When in use, the high-temperature air discharged from the inside of the oven is discharged into the second intake pipe through the first outlet pipe, and then discharged into the heat exchange core through the second intake pipe.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1 - 6, the present utility model provides a technical solution: a high-efficiency exchanger, including an exchange mechanism 1 and an oven 105 installed on the top of the exchange mechanism 1. An energy recovery mechanism 2 is arranged inside the exchange mechanism 1, and an opening and closing motor 205 is arranged on one side inside the energy recovery mechanism 2. The exchange mechanism 1 includes an exchange box 101. A first air inlet 102 is opened at the center of the top of the exchange box 101, and an exhaust port 103 is opened at the center of the bottom of the exchange box 101. Among them, a exhaust pipe 104 is fixedly installed at the bottom of the exchange box 101 near the exhaust port 103. The oven 105 is fixedly installed on the top of the exchange box 101 near the first air inlet 102. Among them, a number of air guiding brackets 106 are fixedly installed inside the exchange box 101, and the air guiding brackets 106 are arranged staggeredly inside the exchange box 101. A first limiting plate 107 is fixedly installed on one side inside the air guiding bracket 106, and a second limiting plate 108 is fixedly installed on the side of the air guiding bracket 106 away from the first limiting plate 107. A rotating motor 109 is fixedly installed on one side inside the air guiding bracket 106. The output end of the rotating motor 109 is fixedly connected to a rotating main gear 110. A transmission chain 111 is meshed on the outside of the rotating main gear 110. A number of rotating driven gears 112 are meshed inside the transmission chain 111. One side of the rotating driven gear 112 and the rotating main gear 110 are both fixedly connected to a rotating air guiding plate 113. A limiting card slot 114 is opened on one side of the top of the rotating air guiding plate 113. The rotating air guiding plates 113 are snap-connected through the limiting card slots 114. Air inlet connecting pipes 115 are symmetrically installed on one side of the top of the oven 105. A first heat exchange serpentine pipe 116 is fixedly connected to the bottom of the air inlet connecting pipe 115. The end of the first heat exchange serpentine pipe 116 is fixedly connected to a second air inlet 117. The first heat exchange serpentine pipe 116 penetrates through the inside of the exchange box 101. By setting the exchange mechanism 1, not only can the heat exchange be realized by using the exchange box 101, but also the hot air blown out by the oven 105 can be guided to flow through the staggered air guiding brackets 106 inside the exchange box 101, increasing the flow path of the hot air, so that the hot air blown out by the oven 105 can fully exchange heat with the air entering the first heat exchange serpentine pipe 116, reducing the hot air blown out by the oven 105 while raising the air entering the first heat exchange serpentine pipe 116, realizing the recovery and utilization. At the same time, when the air volume and temperature of the hot air blown out by the oven 105 are small, the rotating motor 109 is started to drive the rotating main gear 110 and the transmission chain 111 to rotate. By using the meshing connection characteristics among the rotating main gear 110, the transmission chain 111 and the rotating driven gears 112, the rotating main gear 110 and the rotating driven gears 112 can drive the rotating air guiding plates 113 to rotate to the vertical direction, reducing the path of the hot air blown out by the oven 105, facilitating the control of the heat of the hot air blown out by the oven 105, and being able to make corresponding adjustments according to needs.

[0031] The energy recovery mechanism 2 includes a second heat exchange serpentine tube 201. The second heat exchange serpentine tube 201 penetrates both sides inside the exchange box 101. One side at the top of the second heat exchange serpentine tube 201 is fixedly installed with a drain port 202, and one side at the bottom of the second heat exchange serpentine tube 201 is fixedly installed with a water inlet 203. A water inlet pipe 204 is fixedly installed on the outer side of the second heat exchange serpentine tube 201 near the water inlet 203. An opening and closing motor 205 is fixedly installed on one side inside the water inlet pipe 204. The output end of the opening and closing motor 205 is fixedly connected to an opening and closing main gear 206. One side of the opening and closing main gear 206 is meshed with a meshing gear disk 207. A number of opening and closing driven gears 208 are meshed with one side of the meshing gear disk 207 close to the opening and closing main gear 206. One side of both the opening and closing main gear 206 and the opening and closing driven gears 208 is fixedly connected to a rotating connection shaft 209. A rotating baffle 210 is fixedly installed on the outer side of the rotating connection shaft 209. One side of the rotating baffle 210 away from the opening and closing main gear 206 and the opening and closing driven gears 208 is rotatably connected to a rotating support block 211. By setting the energy recovery mechanism 2, when the hot air blown out by the oven 105 has a relatively high temperature, water is injected into the inside of the second heat exchange serpentine tube 201 through the water inlet 203, and the hot air blown out by the oven 105 can be used to heat the water, so that the redundant heat can be recovered and utilized, achieving the purpose of saving resources. By starting the opening and closing motor 205 to drive the opening and closing main gear 206 to rotate, using the meshing connection characteristics among the opening and closing main gear 206, the meshing gear disk 207 and the opening and closing driven gears 208, the opening and closing main gear 206 and the opening and closing driven gears 208 drive the rotating connection shaft 209 and the rotating baffle 210 to rotate. By changing the angle of the rotating baffle 210, the flow rate of the water in the water inlet pipe 204 can be adjusted, thereby controlling the heat recovery efficiency.

[0032] Working principle: Before using this high-efficiency exchanger, it is necessary to first check the overall situation of the device to ensure that it can work normally. According to Figure 1 - Figure 6As shown in the figure, first, the heat exchanger 101 is used to achieve heat exchange. The staggered air guide brackets 106 inside the heat exchanger 101 can direct the hot air blown out by the oven 105 to flow, increasing the path of the hot air flow, so that the hot air blown out by the oven 105 and the air entering the first heat exchange serpentine tube 116 can conduct sufficient heat exchange, reducing the hot air blown out by the oven 105 while increasing the temperature of the air entering the first heat exchange serpentine tube 116, achieving energy recovery and utilization. At the same time, when the air volume and temperature of the hot air blown out by the oven 105 are small, the rotation motor 109 is started to drive the rotation of the main rotation gear 110 and the drive chain 111. Utilizing the meshing connection characteristics among the main rotation gear 110, the drive chain 111 and the driven rotation gear 112, the main rotation gear 110 and the driven rotation gear 112 can drive the rotation guide plate 113 to rotate to the vertical direction, reducing the path of the hot air blown out by the oven 105, facilitating the control of the heat of the hot air blown out by the oven 105, and enabling corresponding adjustment according to needs. Secondly, when the temperature of the hot air blown out by the oven 105 is relatively high, water is injected into the interior of the second heat exchange serpentine tube 201 through the water inlet 203, and the hot air blown out by the oven 105 can be used to heat the water, thereby achieving the recovery and utilization of excess heat and achieving the purpose of saving resources. By starting the opening and closing motor 205 to drive the rotation of the opening and closing main gear 206, and utilizing the meshing connection characteristics among the opening and closing main gear 206, the meshing gear disc 207 and the opening and closing driven gear 208, the opening and closing main gear 206 and the opening and closing driven gear 208 drive the rotation connection shaft 209 and the rotation baffle 210 to rotate. By changing the angle of the rotation baffle 210, the flow rate of the water in the water inlet pipe 204 can be adjusted, thereby controlling the efficiency of heat recovery.
