The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] This utility model provides an exhaust gas air cooler, including a housing 101 and a simplified multi-stage cooling assembly. The simplified multi-stage cooling assembly includes a heat exchange tube bundle 102, a mounting frame 109, a connecting frame 111, a fan 112, a ventilation hole 110, an extension frame 103, a louvered fan 104, an upper rotating shaft 105, a lower rotating shaft 106, a linkage belt 107, and a control wheel 108. This solution solves the problems of traditional exhaust gas cooling equipment having a single cooling method, being unable to flexibly adjust according to the actual temperature and flow rate of the exhaust gas, resulting in poor cooling effect and high maintenance costs. In use, high-temperature exhaust gas enters the air cooler through a pre-set inlet in the housing 101, directly contacting the heat exchange tube bundle 102. The fan 112 is then turned on, and the airflow generated by the fan passes through the ventilation hole 110. The airflow is accelerated by entering the space between the mounting frame 109 and the outer casing 101. The flowing air exchanges heat with the exhaust gas in the heat exchange tube bundle 102, carrying away the heat from the exhaust gas. When it is necessary to adjust the air intake, the control wheel 108 is rotated. The control wheel 108 drives the upper rotating shaft 105 to rotate. The upper rotating shaft 105 drives the lower rotating shaft 106 to rotate synchronously through the linkage belt 107, thereby realizing the angle adjustment of the louvered fan 104. When the exhaust gas temperature is high, rotating the control wheel 108 increases the opening angle of the louvered fan 104, increasing the air intake and enhancing the cooling effect. When the exhaust gas temperature is low, the opening angle of the louvered fan 104 is reduced to reduce unnecessary energy consumption. Thus, the problems existing in traditional exhaust gas cooling equipment are effectively solved.

[0023] In this specific embodiment, the heat exchange tube bundle 102 is detachably connected to the outer shell 101 and located on the inner wall of the outer shell 101. The mounting bracket 109 is detachably connected to the outer shell 101 and located on one side of the inner shell 101, with the mounting bracket 109 disposed on one side of the heat exchange tube bundle 102. The connecting bracket 111 is fixedly connected to the mounting bracket 109 and located on the inner side of the mounting bracket 109 away from the outer shell 101, with the connecting bracket 111 perpendicular to the outer shell 101. The fan 112 is detachably connected to the connecting bracket 111 and positioned... The connecting frame 111 is located on the side of the outer casing 101, and the fan 112 is located on the side of the mounting frame 109 near the inside of the outer casing 101. According to the actual usage scenario and installation requirements, the outer casing 101 is placed in a stable and suitable position and firmly fixed by means of anchor bolts, etc., to ensure that the outer casing 101 will not shift or shake during equipment operation. The heat exchange tube bundle 102 is the main component for heat exchange operation and can effectively ensure the heat exchange effect. The mounting frame 109 and the connecting frame 111 are the main structural components for mounting and connecting the fan 112.

[0024] The ventilation hole 110 is fixedly connected to the mounting frame 109 and is located on the inner side of the mounting frame 109. The ventilation hole 110 is also located on one side of the connecting frame 111. The air force generated by the fan 112 enters the space between the mounting frame 109 and the outer shell 101 through the ventilation hole 110, accelerating the air flow.

[0025] Secondly, the extension frame 103 is detachably connected to the outer casing 101 and is located on the side of the outer casing 101 away from the mounting frame 109, and the louvered fan 104 is disposed on the inner side of the extension frame 103 away from the outer casing 101.

[0026] Meanwhile, the upper rotating shaft 105 is rotatably connected to the extension frame 103 and is located inside the upper part of the extension frame 103. One end of the upper rotating shaft 105 passes through the extension frame 103 and is located on the outer side of the extension frame 103. The upper rotating shaft 105 is also detachably connected to the louvered fan 104 and is located above the louvered fan 104. The lower rotating shaft 106 is rotatably connected to the extension frame 103 and is located inside the lower part of the extension frame 103. One end of the lower rotating shaft 106 passes through the extension frame 103 and is positioned below the upper rotating shaft 105. The lower rotating shaft 106 is also detachably connected to the louvered fan 104 and is located on the lower side of the louvered fan 104. When it is necessary to adjust the air intake, the control wheel 108 is rotated, which drives the upper rotating shaft 105 to rotate. The upper rotating shaft 105 drives the lower rotating shaft 106 to rotate synchronously through the linkage belt 107, thereby realizing the angle adjustment of the louvered fan 104.

[0027] In addition, the linkage belt 107 is disposed on the outer surface of the upper rotating shaft 105 and the lower rotating shaft 106. The control wheel 108 is fixedly connected to the upper rotating shaft 105 and is located at the end of the upper rotating shaft 105 away from the extension frame 103. When it is necessary to adjust the air intake, the control wheel 108 is rotated, and the control wheel 108 drives the upper rotating shaft 105 to rotate. The upper rotating shaft 105 drives the lower rotating shaft 106 to rotate synchronously through the linkage belt 107, thereby realizing the angle adjustment of the louvered fan 104.

[0028] When using this invention, high-temperature exhaust gas enters the air cooler through the pre-set inlet of the outer casing 101, directly contacting the heat exchange tube bundle 102. The fan 112 is then turned on, and the airflow generated by the fan 112 enters the space between the mounting frame 109 and the outer casing 101 through the ventilation hole 110, accelerating airflow. The flowing air exchanges heat with the exhaust gas inside the heat exchange tube bundle 102, carrying away the heat from the exhaust gas. When it is necessary to adjust the airflow, the control wheel 108 is rotated. The control wheel 108 drives the upper rotating shaft 105 to rotate, and the upper rotating shaft 105 drives the lower rotating shaft 106 to rotate synchronously via the linkage belt 107, thereby adjusting the angle of the louvered fan 104. When the exhaust gas temperature is high, rotating the control wheel 108 increases the opening angle of the louvered fan 104, increasing the airflow and enhancing the cooling effect; when the exhaust gas temperature is low, the opening angle of the louvered fan 104 is reduced to decrease unnecessary energy consumption. This effectively solves the problem that traditional exhaust gas cooling equipment has a single cooling method, cannot be flexibly adjusted according to the actual temperature and flow of the exhaust gas, resulting in poor cooling effect and high maintenance cost.
