Description

Technical Field

[0001] This utility model relates to the field of heat exchanger processing technology, and in particular to a finned cooling device for heat exchanger processing. Background Technology

[0002] In the manufacturing process of heat exchangers, fins are the core heat exchange elements, and their processing quality directly affects the overall performance of the heat exchanger. Fins usually need to be formed through multiple processes such as stamping and cutting. In some processing processes, fins will generate a lot of heat due to friction and plastic deformation during processing, and need to be cooled.

[0003] Currently, the industry mostly uses natural cooling or simple air-cooling and water-cooling devices for fin cooling. Natural cooling is inefficient and cannot meet the cycle time requirements of large-scale production. Traditional air-cooling devices often have problems with poor sealing of the cooling chamber, allowing cold air to easily escape from the inlet and outlet, resulting in large temperature fluctuations and unstable cooling effects. In addition, the refrigeration equipment needs to be frequently started to maintain the set temperature, resulting in high energy consumption. Some water-cooling devices may cause condensation on the fin surface due to improper water volume control, affecting subsequent processing. Therefore, we need to upgrade and modify the existing technology to overcome the existing problems and shortcomings. Utility Model Content

[0004] The purpose of this invention is to provide a finned cooling device for heat exchanger processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a fin cooling device for heat exchanger processing, including a cooling chamber, a cold air fan, an air curtain assembly, and a monitoring assembly. A conveyor belt is installed through the interior of the cooling chamber. The cold air fan is located at the upper end of the cooling chamber, and a cooling pipe is installed at the lower end of the cold air fan inside the cooling chamber. The air curtain assembly is located at the inlet and outlet of the cooling chamber, and the monitoring assembly is installed inside the cooling chamber.

[0007] The air curtain assembly includes two sets of mounting brackets fixed at the upper end of the inlet and outlet of the cooling chamber. An air curtain fan is provided at the upper end of the mounting bracket, and an air outlet pipe is connected to the lower end of the air curtain fan.

[0008] The monitoring component includes a control panel, on the inside of which a first temperature sensor and an infrared temperature sensor are connected.

[0009] Preferably, the mounting bracket has an embedded groove at its lower end, and the air outlet pipe has a rotating shaft at its upper end. The air outlet pipe is rotatably connected to the lower end of the embedded groove via the rotating shaft.

[0010] Preferably, the air outlet duct structure adopts a flat nozzle design, and its width is adapted to the width of the conveyor belt to ensure that the air curtain can cover the full width of the conveyor belt. A guide plate is provided at the air outlet duct to reduce edge air leakage.

[0011] Preferably, the air curtain fan is a variable frequency fan and is electrically connected to the control panel, capable of receiving cooling room temperature data monitored by the first temperature sensor.

[0012] Preferably, the first temperature sensor is a PT platinum resistance sensor, and at least one is provided at the top, bottom and middle of the cooling chamber. The first temperature sensor is electrically connected to the controller inside the control panel.

[0013] Preferably, the infrared temperature sensor is a sensor with an x-pixel array, and its installation position corresponds to the conveyor path of the conveyor belt, which can cover the running trajectory of the fins. The infrared temperature sensor is connected to the control panel.

[0014] Preferably, the controller inside the control panel is an STM microcontroller, which can receive data transmitted from the first temperature sensor and the infrared temperature sensor, and control the operation of the air cooler and the air curtain fan according to a preset program.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention features an air curtain assembly within the device. An air curtain fan blows air through the air outlet duct, forming an air curtain at the air inlet and outlet of the cooling chamber. This air curtain blocks the contact between the internal cold air and the external air, thus achieving heat preservation of the internal environment of the cooling chamber. This facilitates the maintenance of a stable temperature within the cooling chamber, prevents fluctuations in cooling effect due to cold air loss, ensures uniform cooling of the fins, reduces the frequency of starting and stopping the air cooler, extends the service life of the air cooler, and also reduces the amount of external dust and impurities entering the cooling chamber with the air.

[0017] This invention incorporates a monitoring component within the device. A first temperature sensor monitors the internal temperature of the cooling chamber, while an infrared temperature sensor monitors the fin temperature. The control panel adjusts the operating power of the cooling fan, enabling constant temperature control of the cooling chamber and fins. This allows for real-time monitoring of the internal temperature distribution and fin cooling status, timely detection and rapid adjustment of localized temperature anomalies, ensuring that each fin meets the preset cooling standard and improving the automation and stability of the cooling process.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1-4 As shown, this embodiment provides a fin cooling device for heat exchanger processing, including a cooling chamber 1, a cold air fan 3, an air curtain assembly 4, and a monitoring assembly 5. A conveyor belt 2 is installed through the interior of the cooling chamber 1. The cold air fan 3 is located at the upper end of the cooling chamber 1, and a cooling pipe 31 is installed at the lower end of the cold air fan 3 inside the cooling chamber 1. The air curtain assembly 4 is located at the inlet and outlet of the cooling chamber 1, and the monitoring assembly 5 is installed inside the cooling chamber 1.

[0027] In this embodiment, the air curtain assembly 4 includes two sets of mounting brackets 41 fixed to the upper ends of the inlet and outlet of the cooling chamber 1. An air curtain fan 42 is mounted on the upper end of each mounting bracket 41, and an air outlet duct 43 is connected to the lower end of the air curtain fan 42. An embedded groove 44 is provided at the lower end of each mounting bracket 41, and a rotating shaft 45 is provided on the upper end of the air outlet duct 43. The air outlet duct 43 is rotatably connected to the lower end of the embedded groove 44 via the rotating shaft 45. The air outlet duct 43 adopts a flat nozzle design, and its width is adapted to the width of the conveyor belt 2 to ensure that the air curtain can cover the full width of the conveyor belt 2. A guide plate is provided at the air outlet duct 43 to reduce edge air leakage. The air curtain fan 42 is a variable frequency fan and is electrically connected to the control panel 51. It can receive temperature data inside the cooling chamber 1 monitored by the first temperature sensor 52, and blow air through the air curtain fan 42. The angle of the air outlet duct 43 can be adjusted by the rotating shaft 45. An air curtain is formed at the air inlet and outlet of the cooling chamber 1 through the air outlet duct 43, blocking the contact between the internal cold air and the external air. This can achieve the temperature preservation operation of the internal environment of the cooling chamber 1, which is conducive to maintaining the temperature stability inside the cooling chamber 1 and avoiding fluctuations in the cooling effect due to the loss of cold air, thereby ensuring the uniformity of fin cooling. At the same time, it reduces the frequent start and stop of the air cooler 3, reduces equipment energy consumption, and extends the service life of the air cooler 3. It can also reduce the entry of external dust and impurities into the cooling chamber 1 with the air.

[0028] In this embodiment, the monitoring component 5 includes a control panel 51. A first temperature sensor 52 and an infrared temperature sensor 53 are connected to the inside of the control panel 51. The first temperature sensor 52 is a PT100 platinum resistance sensor, with at least one located at the top, bottom, and middle of the cooling chamber 1. The first temperature sensor 52 is electrically connected to a controller inside the control panel 51. The infrared temperature sensor 53 is a sensor with an 8x8 pixel array, and its installation position corresponds to the conveyor path of the conveyor belt 2, covering the running trajectory of the fins. The infrared temperature sensor 53 is connected to the control panel 51. The controller inside the control panel 51 is an STM32 microcontroller capable of receiving the first temperature sensor... The data transmitted by the first temperature sensor 52 and the infrared temperature sensor 53 are used to control the operation of the air cooler 3 and the air curtain fan 42 according to the preset program. The internal temperature of the cooling chamber 1 is monitored by the first temperature sensor 52, and the fin temperature is monitored by the infrared temperature sensor 53. The operating power of the air cooler 3 is adjusted by the control panel 51. This enables constant temperature operation control of the cooling chamber 1 and the fins, which facilitates real-time monitoring of the internal temperature field distribution and fin cooling status of the cooling chamber 1, timely detection of local temperature anomalies and rapid adjustment, and ensures that each fin meets the preset cooling standard. At the same time, closed-loop control is formed through data feedback, reducing manual intervention and improving the automation and stability of the cooling process.

[0029] The working principle and process of this utility model are as follows: During operation, the fins to be cooled are conveyed into the cooling chamber 1 by the conveyor belt 2. After the air cooler 3 is started, cold air is delivered into the cooling chamber 1 through the cooling pipe 31 to provide a cooling environment for the fins. The air curtain fan 42 receives the temperature data of the cooling chamber 1 monitored by the first temperature sensor 52 and forms an air curtain at the inlet and outlet of the cooling chamber 1 through the air outlet pipe 43, which effectively blocks the cold air inside the cooling chamber 1 from contacting the outside air and maintains the internal temperature stability. The first temperature sensor 52 monitors the internal temperature, and the infrared temperature sensor 53 monitors the surface temperature of the fins along the path of the conveyor belt 2. Both transmit the data to the control panel 51. The controller analyzes the data according to the preset program and dynamically adjusts the operating power of the air cooler 3 and the air supply intensity of the air curtain fan 42 to form a closed-loop control.
