Description

Technical Field

[0001] The present invention relates to the technical field of heat exchanger heat dissipation, and more specifically to a heat exchanger heat dissipation efficiency detection device. Background Art

[0002] Heat exchangers are key equipment widely used in many fields such as industry, automobiles, air conditioning, refrigeration, etc. Their main function is to transfer heat between two fluids to meet specific process requirements. Heat dissipation efficiency is one of the important indicators for evaluating the performance of heat exchangers. Efficient heat exchangers can significantly improve the overall energy efficiency of the system, reduce energy consumption, and extend the service life of the equipment. However, due to the influence of various factors, the actual heat dissipation efficiency of the heat exchanger may decrease, thus affecting the performance and reliability of the system. In order to ensure the performance and quality of the heat exchanger, it is necessary to test the heat dissipation efficiency of the equipment.

[0003] At present, the heat exchanger heat dissipation efficiency detection methods mainly include temperature measurement method, pressure measurement method and flow measurement method. The temperature measurement method calculates the heat transfer efficiency by measuring the temperature difference between the inlet and outlet of the heat exchanger; the pressure measurement method evaluates the fluid flow state by measuring the pressure drop between the inlet and outlet; the flow measurement method measures the fluid flow rate to ensure that the flow rate is within the design range. Although these methods can evaluate the heat dissipation efficiency of the heat exchanger to a certain extent, their detection methods are single.

[0004] Current testing methods typically focus on a single parameter, such as temperature, pressure, or flow, and fail to conduct a comprehensive evaluation. The performance of a heat exchanger is affected by many factors, and the test results of a single parameter may not fully reflect its actual performance. For example, when testing the heat dissipation efficiency of a heat exchanger, a gas leak in the heat exchanger will cause uniformity problems with the fluid, thereby affecting the heat dissipation efficiency of the heat exchanger. Similarly, when scaling occurs on the surface of a gas heat exchanger, it will also cause uniformity problems with the fluid, which in turn affects the heat dissipation efficiency. Existing testing methods cannot accurately distinguish between these two situations, requiring maintenance personnel to perform multiple tests on the heat exchanger, a cumbersome and time-consuming process.

[0018] Compared with the prior art, the above technical solution provided by the present invention has at least the following beneficial effects:

[0019] (1) This scheme is provided with a distance detection mechanism and a heat dissipation detection mechanism.

[0021] (3) By providing a blocking mechanism and a distance detection mechanism, when the circular slide cannot continue to move upward, it indicates that the gas flow entering the gas tank is large, which may be due to leakage in the heat exchanger body. When the airflow is weak, the circular slide moves upward slowly and may not touch the first and second blocking plates, or even if it touches, it will not trigger the closing action of the blocking plates. At this time, the circular slide will continue to move upward, indicating that the gas flow entering the gas tank is small, which may be due to scaling inside the heat exchanger body or blockage of the flow channel. During the above operation, the magnetic force of the blocking mechanism and the design of the torsion spring ensure the precise control of the circular slide and improve the detection accuracy.

[0039] The following is a detailed description of a heat exchanger heat dissipation efficiency detection device provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the present invention.

[0040] like Figures 1 to 8As shown, an embodiment of the present invention provides a heat exchanger heat dissipation efficiency detection device, comprising a heat exchanger body 1, both sides of the outer surface of the heat exchanger body 1 are provided with an air inlet pipe 2 for air intake and an air outlet pipe 3 for exhaust gas discharge, a distance detection mechanism 4 is provided on the front side of the outer surface of the heat exchanger body 1, the distance detection mechanism 4 comprises a first gas storage tank 41 and a second gas storage tank 42 fixedly connected to the front side of the outer surface of the heat exchanger body 1, the bottoms of the first gas storage tank 41 and the second gas storage tank 42 are respectively fixedly connected with a first flow pipe 43 and a second flow pipe 44, and one side of the outer surface of the first gas storage tank 41 and the second gas storage tank 42 is provided with a heat dissipation detection mechanism 7 for respectively testing the inlet and outlet temperatures of the heat exchanger body 1;

[0041] Among them, the heat dissipation detection mechanism 7 includes a water tank 71 which is arranged on one side of the outer surface of the first gas tank 41 and the second gas tank 42. The top of the water tank 71 is fixedly connected with a tank cover 72. The top of the first gas tank 41 is provided with an air duct 73 for introducing gas into the water tank 71. One end of the air duct 73 passes through the interior of the tank cover 72. A fixing seat 74 is fixedly connected to the middle of one side of the inner wall of the water tank 71. The interior of the fixing seat 74 is fixedly connected with a temperature tester 75 for measuring the water temperature inside the water tank 71.

[0042] In order to solve the problem of the singleness of the existing detection method and the inability to accurately distinguish between gas leakage and scaling, the above technical solution is now adopted to solve the problem. The above technical solution is mainly composed of a distance detection mechanism 4 and a heat dissipation detection mechanism 7. When the heat dissipation efficiency of the heat exchanger body 1 is detected, the gas in the heat exchanger body 1 can be introduced into the first gas tank 41 and the second gas tank 42 respectively through the first flow pipe 43 and the second flow pipe 44. After the gas enters the first gas tank 41, it is introduced into the water tank 71 through the air guide pipe 73. At this time, the change of water temperature can be measured by observing the temperature tester 75 inside the water tank 71 outside the first gas tank 41 and the second gas tank 42 respectively, and the heat dissipation efficiency of the heat exchanger body 1 can be judged by the change of water temperature. When the temperature difference between the two water tanks 71 is large, it means that there is a leakage in the heat exchanger body 1. However, in order to ensure the specific reason for the low heat dissipation efficiency of the heat exchanger body 1, the uniformity of the gas flow can be judged by observing the formation and rising speed of bubbles in the water tank 71 when the gas is passed into the water tank 71. For example, if the bubble formation speed is slow, the number of bubbles is small, and the water temperature does not change much, it means that the heat exchanger body 1 is scaled. When the bubble formation speed is fast, the number of bubbles is large, and the gas flow rate fluctuates significantly, it means that the heat exchanger body 1 is leaking, which leads to excessive pressure and increased airflow. During the above operation, by using a high-precision temperature tester 75, the accuracy of the measurement data is ensured, and the heat dissipation efficiency of the heat exchanger can be monitored in real time without disassembling the heat exchanger, so as to timely discover and solve problems. At the same time, the above technical solution can effectively solve the problems of the singleness of the existing detection method and the inability to accurately distinguish between gas leakage and scaling. The device not only improves the accuracy and efficiency of the detection, but also can perform real-time monitoring without damaging the equipment, ensuring the long-term reliable operation of the heat exchanger. During the above operation, by observing the behavior of the bubbles and the changes in the water temperature, the maintenance personnel can quickly and accurately judge the specific problems of the heat exchanger, and perform maintenance and repair in time, thereby improving the overall performance and reliability of the system.

[0043] like Figure 1 , Figure 2 As shown, the distance detection mechanism 4 also includes a sealing cover 45 fixedly connected to the top of the first gas tank 41 and the second gas tank 42, and the internal structure and function of the first gas tank 41 and the second gas tank 42 are the same; the first gas tank 41 and the second gas tank 42 are fixedly connected to the slide rails 46 on both sides of the inner wall, and the first gas tank 41 and the second gas tank 42 are provided with a fixing rod 47 fixedly connected to the sealing cover 45 inside, and the outer cylindrical surface of the fixing rod 47 is slidably connected to a circular slide plate 48, and the outer cylindrical surface of the circular slide plate 48 is fixedly connected to the clamping plates 49 on both sides.

[0044] like Figure 1 , Figure 2As shown, the first flow pipe 43 and the second flow pipe 44 are fixedly connected to the air inlet channel and the exhaust channel of the heat exchanger body 1 respectively, and the first gas storage tank 41 and the second gas storage tank 42 are both made of transparent glass to facilitate observation of the moving trajectory of the circular slide plate 48.

[0045] When the heat exchanger body 1 is tested for heat dissipation efficiency without stopping the machine, the gas enters the air inlet channel and the exhaust channel of the heat exchanger body 1 through the first flow pipe 43 and the second flow pipe 44, respectively, and then enters the first gas tank 41 and the second gas tank 42, respectively. After the gas enters, the sealing cover 45 is used to ensure the air tightness inside the gas tank to prevent gas leakage. When the gas enters the first gas tank 41 and the second gas tank 42, the circular slide 48 inside is pushed to move upward along the fixed rod 47. The outer circumferential surface of the circular slide 48 is fixedly connected with a card plate 49 on both sides, so that the card plate 49 slides along the slide rails 46 on both sides of the inner wall of the first gas tank 41 to ensure the smooth movement of the circular slide 48. In addition, during the above operation, since the first gas tank 41 and the second gas tank 42 are both made of transparent glass, it is convenient to observe the moving trajectory of the circular slide 48, so that the maintenance personnel can intuitively judge the air flow speed and flow rate. When the air flow speed is very fast, the circular slide 48 will move up faster, which indicates that the gas flow entering the gas tank is large, which may be due to leakage in the heat exchanger body 1. When the air flow speed is slow, the circular slide 48 will move up slower, which indicates that the gas flow entering the gas tank is small, which may be due to scaling or blockage of the flow channel inside the heat exchanger body 1. In the process of detecting the size of the air flow, the gas is introduced into the water tank 71 through the air guide pipe 73. By observing the formation and rising speed of bubbles in the water tank 71, the heat dissipation efficiency and specific problems of the heat exchanger body 1 are comprehensively judged, thereby improving the comprehensiveness and accuracy of the detection. The distance detection mechanism 4 has a simple structure, is easy to install and maintain, and improves the reliability and durability of the equipment. By observing the moving speed of the circular slide 48, the behavior of the bubbles and the change of water temperature, the device allows maintenance personnel to quickly and accurately judge the specific problems of the heat exchanger, and perform maintenance and repair in time, thereby improving the overall performance and reliability of the system.

[0046] like Figure 1 , Figure 2 , Figure 3 As shown, an airflow detection mechanism 5 for detecting the airflow intensity at the inlet and outlet of the heat exchanger body 1 is provided on the other side of the outer circumferential surface of the first air storage tank 41 and the second air storage tank 42. The airflow detection mechanism 5 includes a test tube 51 provided on the other side of the outer circumferential surface of the first air storage tank 41. An exhaust pipe 53 is fixedly connected to the middle of the outer circumferential surface of the test tube 51. A branch pipe 52 is fixedly connected to the bottom of the test tube 51. One end of the branch pipe 52 is fixedly connected to the first flow pipe 43. A push plate 56 is slidably connected to the inner bottom of the test tube 51.

[0047] When the gas enters the air inlet channel and the exhaust channel of the heat exchanger body 1 through the first circulation pipe 43 and the second circulation pipe 44 respectively, and then enters the first gas storage tank 41 and the second gas storage tank 42 respectively, part of the gas enters the test tube 51 from the branch pipe 52 through the external branch pipe 52. Under the push of the gas, the push plate 56 moves upward in the test tube 51. During the movement of the push plate 56, since the outer diameter of the push plate 56 is the same as the inner diameter of the test tube 51, it is ensured that the gas can only be transferred through the movement of the push plate 56. In the process of using gas to push the push plate 56 to move, the strength of the airflow can be judged by recording the time consumed when the push plate 56 reaches the exhaust pipe 53, so that the maintenance personnel can quickly judge the specific reason for the poor heat dissipation efficiency of the heat exchanger body 1.

[0048] like Figure 1 , Figure 2 , Figure 3 As shown, a spring ring 54 is fixedly connected to the inner top of the test tube 51 , and a baffle 55 fixedly connected to the spring ring 54 is arranged inside the test tube 51 . The outer diameters of the push plate 56 and the baffle 55 are the same as the inner diameter of the test tube 51 .

[0049] When the gas enters the air inlet channel and the exhaust channel of the heat exchanger body 1 through the first flow pipe 43 and the second flow pipe 44 respectively, and then enters the first gas storage tank 41 and the second gas storage tank 42 respectively, part of the gas enters the test tube 51 from the branch pipe 52 through the external branch pipe 52. Under the push of the gas, the push plate 56 moves upward in the test tube 51. During the movement of the push plate 56, since the outer diameter of the push plate 56 is the same as the inner diameter of the test tube 51, it is ensured that the gas can only be transferred through the movement of the push plate 56. When the push plate 56 moves to the position of the baffle 55, the baffle 55 moves upward because the gas continuously enters the test tube 51. Under the thrust of the strong airflow, the baffle 55 always moves upward to squeeze the spring coil 54. When the spring coil 54 is squeezed to a certain extent, the baffle 55 will be higher than the position of the exhaust pipe 53. At this time, the gas inside the test tube 51 is discharged from the exhaust pipe 53, and the baffle 55 will slowly return to the initial position. During the above operation, the airflow continues to maintain a strong state, indicating that the gas flow entering the first gas tank 41 is large, which may be due to the presence of a leak in the heat exchanger body 1. When the airflow continues to maintain a weak state, it indicates that the gas flow entering the gas tank is small, which may be due to scaling or blockage of the flow channel inside the heat exchanger body 1. At the same time, during the above operation, the specific reasons for the low heat dissipation efficiency of the heat exchanger body 1 can be specifically analyzed by changing the position of the through baffle 55. That is, when the baffle 55 is in a high position, it indicates that the airflow is very strong, further confirming that there is a leak in the heat exchanger body 1. When the baffle 55 is in a low position, it indicates that the airflow is weak, further confirming that there is scaling or blockage of the flow channel inside the heat exchanger body 1. Through the above technical solution, maintenance personnel can quickly and accurately determine the specific problems of the heat exchanger, and perform maintenance and repairs in a timely manner, thereby improving the overall performance and reliability of the system.

[0050] like Figure 2 , Figure 4 , Figure 5 As shown, the first gas storage tank 41 and the second gas storage tank 42 are both provided with a blocking mechanism 6 for blocking the circular slide 48 from moving upward, and the blocking mechanism 6 includes a first blocking plate 61 and a second blocking plate 63 which are arranged on the front and rear sides of the outer circular surface of the fixing rod 47, and the opening ends of the first blocking plate 61 and the second blocking plate 63 are respectively fixedly connected with a positive magnetic block 62 and a negative magnetic block 64, and one side of the outer surface of the first blocking plate 61 and the second blocking plate 63 is hinged with a U-shaped frame 65, and one side of the outer surface of the U-shaped frame 65 is fixedly connected to the inner wall of the first gas storage tank 41.

[0051] like Figure 2 , Figure 4 , Figure 5 As shown, the first blocking plate 61 and the second blocking plate 63 are both made of plastic; and torsion springs are provided at the connection points between the first blocking plate 61 , the second blocking plate 63 and the U-shaped frame 65 .

[0052] The gas enters the air inlet channel and the exhaust channel of the heat exchanger body 1 through the first flow pipe 43 and the second flow pipe 44, respectively, and then enters the first gas storage tank 41 and the second gas storage tank 42, respectively. After the airflow enters the gas storage tank, the circular slide plate 48 is pushed to move upward along the fixed rod 47. The card plate 49 slides along the slide rails 46 on both sides of the inner wall of the gas storage tank to ensure the smooth movement of the slide plate. When the circular slide plate 48 moves up to the position of the first blocking plate 61 and the second blocking plate 63, the circular slide plate 48 will touch the first blocking plate 61 and the second blocking plate 63. Since the opening ends of the first blocking plate 61 and the second blocking plate 63 are fixedly connected with the positive pole magnetic block 62 and the negative pole magnetic block 64, respectively, the magnetic force between them will cause the first blocking plate 61 and the second blocking plate 63 to attract each other and close to form a closed blocking surface. The U-shaped frame 65 is connected by a hinged manner, so that the first blocking plate 61 and the second blocking plate 63 can rotate freely within a certain range. When the circular slide plate 48 touches them, the closing action of the blocking plate will be triggered. The setting of the torsion spring ensures that the first blocking plate 61 and the second blocking plate 63 remain in an open state when there is no external force. When the circular slide plate 48 moves up, the first blocking plate 61 and the second blocking plate 63 will quickly close to prevent the circular slide plate 48 from continuing to move up. When the airflow is very strong, the circular slide plate 48 will quickly move up and touch the first blocking plate 61 and the second blocking plate 63, triggering the closing action of the blocking plate. At this time, the circular slide plate 48 cannot continue to move up, indicating that the gas flow entering the gas storage tank is large, which may be due to leakage in the heat exchanger body 1. When the airflow is weak, the circular slide plate 48 moves up slowly and may not touch the first blocking plate 61 and the second blocking plate 63, or even if it touches, it will not trigger the closing action of the blocking plate. At this time, the circular slide plate 48 will continue to move up, indicating that the gas flow entering the gas storage tank is small, which may be due to scaling or flow channel blockage inside the heat exchanger body 1. In the above operation process, the magnetic force of the blocking mechanism 6 and the design of the torsion spring ensure the precise control of the circular slide plate 48 and improve the accuracy of detection. At the same time, the heat dissipation efficiency and specific problems of the heat exchanger are comprehensively judged through the moving speed of the circular slide plate 48 and the response of the blocking mechanism 6, thereby improving the comprehensiveness and accuracy of the detection.

[0053] like Figure 1 , Figure 6 , Figure 8 As shown, a feeding mechanism 8 for feeding the water storage tank 71 is provided on the top of the heat exchanger body 1. The feeding mechanism 8 includes a storage tank 81 fixedly connected to the top of the heat exchanger body 1. The top of the outer cylindrical surface of the storage tank 81 is fixedly connected with a discharge port 82. The positions of the discharge ports 82 on both sides of the storage tank 81 are fixedly connected with a feeding pipe 83. The feeding pipe 83 is fixedly passed through the interior of the water storage tank 71.

[0054] like Figure 1 , Figure 6 , Figure 8 As shown, an electric telescopic rod 84 fixedly connected to the heat exchanger body 1 is provided on one side of the outer circular surface of the storage tank 81, and a U-shaped rod 85 is fixedly connected to the top of the electric telescopic rod 84, and one end of the U-shaped rod 85 passes through the interior of the storage tank 81 and is fixedly connected to a support plate 86.

[0055] like Figure 1 , Figure 6 , Figure 8 As shown, the outer diameter of the support plate 86 is the same as the inner diameter of the storage tank 81, and the storage tank 81 is made of transparent plastic.

[0056] When the heat exchanger body 1 is used to treat the exhaust gas, since the exhaust gas contains harmful gases, such as sulfur dioxide and nitrogen oxides, in the process of detecting the heat dissipation efficiency, firstly, half of the capacity of the phenolphthalein reagent is pre-filled into the storage tank 81 to detect the harmful gases in the exhaust gas. When it is necessary to add the phenolphthalein reagent to the water storage tank 71, the electric telescopic rod 84 is started to gradually extend it. The extension of the electric telescopic rod 84 drives the U-shaped rod 85 to move upward, and then drives the support plate 86 to move upward. When the support plate 86 moves upward, the phenolphthalein reagent in the storage tank 81 flows into the feed pipe 83 through the discharge port 82, and then the phenolphthalein reagent is transported to the inside of the water storage tank 71 through the feed pipe 83. The exhaust gas enters the water storage tank 71 through the air guide pipe 73 and mixes with the phenolphthalein reagent in the water storage tank 71. By observing the color change of the water in the water storage tank 71, it is judged whether the exhaust gas contains harmful gases. When the pH value and color of the water do not change significantly, it means that there are no harmful gases in the exhaust gas. When the pH value of water increases and the aqueous solution turns red, it indicates that the exhaust gas contains alkaline components, and further determines that the heat exchanger body 1 may be leaking. The above technical solution can effectively solve the problem of harmful gas detection in the process of exhaust gas treatment by the heat exchanger body 1. The device not only improves the accuracy and efficiency of detection, but also realizes the automation and visualization of the detection process, ensuring the stable operation of the system. By observing the color change of the water in the water storage tank 71, maintenance personnel can quickly and accurately determine whether there are harmful gases in the exhaust gas, and perform maintenance and adjustments in time, thereby improving the overall performance and reliability of the system.

[0057] When the present invention is in use, the gas enters the air inlet channel and the exhaust channel of the heat exchanger body 1 through the first flow pipe 43 and the second flow pipe 44 respectively, and then enters the first gas storage tank 41 and the second gas storage tank 42 respectively. After the airflow enters the gas storage tank, it pushes the circular slide plate 48 to move upward along the fixed rod 47. The card plate 49 slides along the slide rails 46 on both sides of the inner wall of the gas storage tank to ensure the smooth movement of the slide plate. When the circular slide plate 48 moves up to the position of the first blocking plate 61 and the second blocking plate 63, the circular slide plate 48 will touch the first blocking plate 61 and the second blocking plate 63. Since the opening ends of the first blocking plate 61 and the second blocking plate 63 are fixedly connected with the positive pole magnetic block 62 and the negative pole magnetic block 64 respectively, the magnetic force between them will cause the first blocking plate 61 and the second blocking plate 63 to attract each other and close to form a closed blocking surface. The U-shaped frame 65 is connected by a hinged manner, so that the first blocking plate 61 and the second blocking plate 63 can rotate freely within a certain range. When the circular slide plate 48 touches them, the closing action of the blocking plate will be triggered. The setting of the torsion spring ensures that the first blocking plate 61 and the second blocking plate 63 remain open when there is no external force. When the circular slide plate 48 moves up, the first blocking plate 61 and the second blocking plate 63 will quickly close to prevent the circular slide plate 48 from moving up further. When the airflow is very strong, the circular slide plate 48 will quickly move up and touch the first blocking plate 61 and the second blocking plate 63, triggering the closing action of the blocking plate. At this time, the circular slide plate 48 cannot move up further, indicating that the gas flow entering the gas storage tank is large, which may be due to leakage in the heat exchanger body 1. When the airflow is weak, the circular slide plate 48 moves up slowly and may not touch the first blocking plate 61 and the second blocking plate 63, or even if it touches, it will not trigger the closing action of the blocking plate. At this time, the circular slide plate 48 will continue to move up, indicating that the gas flow entering the gas storage tank is small, which may be due to scaling or blockage of the flow channel inside the heat exchanger body 1. The gas entering the first gas storage tank 41 is introduced into the water storage tank 71 through the air guide pipe 73. At this time, the temperature tester 75 is used to measure the change in the water temperature inside the water tank 71 to determine the heat dissipation efficiency of the heat exchanger body 1. The uniformity of the gas flow rate can be further determined by observing the formation and rising speed of bubbles in the water tank 71. When the bubble formation speed is slow, the number of bubbles is small, and the water temperature does not change much: it indicates that the heat exchanger body 1 is scaled. When the bubble formation speed is fast and the number of bubbles is large, it indicates that the heat exchanger body 1 is leaking, resulting in excessive pressure and increased airflow.
