Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology, specifically to a rapid cooling device. Background Technology

[0002] In the manufacturing process of control cabinets, metal sheets often require heat treatment to improve their mechanical properties. After heat treatment, the cooling process is crucial, directly affecting the material's microstructure and final strength. Currently, blowers are commonly used to cool the workpieces, using forced airflow to remove surface heat. However, this method has significant limitations: blowers typically blow air from a single direction, resulting in uneven airflow distribution. Airflow is restricted on the back or in localized areas of the workpiece, creating "insufficiently cooled" zones and causing overall uneven cooling.

[0003] This uneven cooling not only prolongs the cooling time and reduces heat treatment efficiency, but may also cause uneven stress distribution within the workpiece, leading to deformation or a decline in mechanical properties and affecting product quality. Furthermore, some equipment uses a honeycomb-shaped cold air outlet design, which, while increasing the contact area between the cold air and the workpiece, significantly reduces the airflow velocity, especially in the central area of ​​the outlet, resulting in a phenomenon of "weak cooling in the middle and strong cooling at the edges," further weakening the uniformity and effectiveness of cooling.

[0004] In view of the shortcomings of the prior art, this utility model provides a rapid cooling device to solve the above problems. Utility Model Content

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] This embodiment discloses a rapid cooling device, according to the attached... Figure 1 To be continued Figure 6 As shown, the device includes a cabinet 1, an inner box 3 is fixedly installed inside the cabinet 1, and a placement plate 4 is fixedly installed on the inner wall of the inner box 3. The placement plate 4 divides the inner cavity of the inner box 3 into two cooling chambers, which are used to place metal plates. A circulation chamber 2 is provided between the inner box 3 and the cabinet 1, and a cooling unit 6 is provided inside the circulation chamber 2.

[0041] The refrigeration unit 6 consists of a refrigeration unit 61, a delivery pipeline unit, heat exchange tubes 64, and a return pipeline unit. The refrigeration unit 61 is connected to several heat exchange tubes 64 through the delivery pipeline unit. Each heat exchange tube 64 is arranged in a wavy pattern, and the heat exchange tubes 64 are arranged at equal intervals at the upper and lower ends of the inner box 3. The delivery pipeline unit consists of a water supply pipe 62 and a branch pipe 63. The water supply pipe 62 is connected to the refrigeration unit 61, and one end of the branch pipe 63 is inserted into the circulation chamber 2. 63 is connected, and the branch pipe 63 is connected to several heat exchange pipes 64. The return pipe unit consists of a convergence pipe 65, a return pipe 66, and a delivery pipe 67. The convergence pipe 65 is connected to the heat exchange pipes 64 to collect cold water. The cold water returns to the return pipe 66 connected to the convergence pipe 65. One end of the return pipe 66 passes through the circulation chamber 2 and is connected to the delivery pipe 67. The delivery pipe 67 is connected to the refrigerator 61, so that the cold water returns to the refrigerator 61 through the convergence pipe 65, the return pipe 66, and the delivery pipe 67.

[0042] The chiller 61 consists of a cold water tank, a refrigeration system, and a water pump. The water in the cold water tank is cooled by the refrigeration system, and then the water pump delivers the cold water through the pipeline to the water supply pipe 62. Then the hot water flows back to the cold water tank from the supply pipe 67.

[0043] Multiple sets of symmetrically arranged blower units 5 are provided on the inner wall of the cooling chamber. One blower unit 5 in each set is used to blow the cold air inside the circulation chamber 2 onto the metal plate, and the other opposite blower unit 5 is used to transport the hot air in the cooling chamber to the inside of the circulation chamber 2, so that the hot air flows along the circulation chamber 2 to the heat exchange pipe 64, and the heat exchange pipe 64 cools the hot air.

[0044] The blower unit 5 consists of a housing 51, a motor 52, a first fan 53, a synchronization assembly, a rotating rod 57, a second fan 58, a vent 511, a limiting plate 512, and bolts 513. The housing 51 is positioned by the limiting plates 512 on its upper and lower sides, allowing it to be inserted into the inner wall of the inner casing 3. The bolts 513 are threadedly connected to the limiting plates 512 and pass through the interior of the inner casing 3, thus securing the motor 52 within the housing 51. Vents 511 are provided on both the left and right sides of the housing 51 for the flow of cool air. The first fan 53 is fixedly mounted on the output shaft of the motor 52. The output end of the motor 52 is connected to the synchronization assembly, which consists of a first synchronous pulley 54, a synchronous belt 55, and a second synchronous pulley 56. The first synchronous pulley 54... The first synchronous pulley 54 is fixedly connected to the output shaft of the motor 52. The surface of the first synchronous pulley 54 is rotatably connected to the synchronous belt 55. The other side of the synchronous belt 55 is rotatably connected to the second fan 58. The second fan 58 is fixedly installed on the surface of the rotating rod 57, and the rotating rod 57 is rotatably connected to the inner wall of the housing 51. One end of the rotating rod 57 is fixedly connected to the second fan 58, so that the motor 52 drives the first fan 53 to rotate synchronously with the first synchronous pulley 54. The rotation of the first synchronous pulley 54 drives the second synchronous pulley 56 to rotate synchronously through the synchronous belt 55. The rotation of the second synchronous pulley 56 drives the rotating rod 57 to rotate. The rotation of the rotating rod 57 drives the second fan 58 to rotate. The second fan 58 rotates synchronously with the first fan 53, so that the cold air inside the circulation chamber 2 flows from the vent 511 to the metal plate for rapid cooling of the metal plate.

[0045] Example 1: This example uses rapid cooling of a metal sheet as an example, combined with the attached... Figure 1 Detailed Workflow: The workflow is as follows: After the metal sheet is placed in the cooling chamber, two symmetrically arranged blower units 5 are activated. The motor 52 of one blower unit rotates forward, driving the first fan 53 and the first synchronous pulley 54 to rotate synchronously. Power is transmitted to the second synchronous pulley 56 via the synchronous belt 55, which in turn drives the rotating rod 57 and the second fan 58 to rotate. At this time, the fan on this side blows the cold air from the circulation chamber 2 out through the vent 511, directly acting on the surface of the metal sheet to achieve forced cooling.

[0046] Meanwhile, the motor 52 of the blower unit 5 on the other side runs in reverse, driving its corresponding first fan 53 and first synchronous pulley 54 to rotate in the opposite direction. Through the synchronous belt 55, second synchronous pulley 56, and rotating rod 57, the second fan 58 rotates in the opposite direction. The fan on this side plays a suction role, drawing the heated air in the cooling chamber out through the vent 511 and returning it to the circulation chamber 2 for cooling and reuse.

[0047] Through the coordinated operation of the two blower units 5—one side delivers cold air and the other side draws hot air—a directional and accelerated airflow circulation is formed within the cooling chamber, significantly improving airflow efficiency and heat exchange rate. This counter-current airflow design breaks away from the uneven cooling problem caused by traditional unidirectional airflow and avoids the phenomenon of "insufficient cooling at the center and excessive cooling at the edges" caused by the decrease in air velocity in the middle of the honeycomb air outlet.

[0048] This structure enhances the uniformity of cold air coverage across the entire sheet surface through an alternating forward and reverse air supply and return mechanism, accelerates the overall heat dissipation speed, effectively reduces thermal stress concentration and deformation risk, and thus improves the cooling uniformity of the metal sheet after heat treatment.

[0049] Example 2: This example uses rapid air cooling as an example, combined with the attached... Figure 1 Detailed Workflow: The workflow is as follows: After the chiller 61 starts, it delivers cooled water through the water supply pipe 62 to the distribution pipe 63, which then distributes the cooled water evenly into multiple heat exchange pipes 64. These heat exchange pipes 64 are arranged within the circulation chamber 2, forming a highly efficient heat exchange channel.

[0050] When hot air flows in the circulation chamber 2, it passes over the surface of the heat exchange tube 64, where the heat is absorbed by the cold water flowing inside the tube, achieving indirect heat exchange between gas and liquid. The air temperature is thus significantly reduced, transforming into cold air, which continues to flow along the air path of the circulation chamber 2 towards the blower unit 5.

[0051] After the cold air reaches the blower unit 5, it enters the area in front of the vent 511. At this time, the motor 52 in the blower unit 5 drives the first fan 53 to rotate, and at the same time drives the rotating rod 57 and the second fan 58 to rotate synchronously through the synchronization component. The two fans work together to generate stable airflow power, which powerfully blows the cold air from the circulation chamber from the vent 511 to the surface of the metal plate in the cooling chamber, achieving efficient and uniform forced cooling.

[0052] This system achieves continuous preparation and directional delivery of cold air through the organic combination of refrigeration cycle and air duct system. It has high heat exchange efficiency and reasonable airflow organization, ensuring that the metal plate is cooled evenly and dissipates heat rapidly during the cooling process.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
