A cooler core fin air drying device

Abstract

This utility model discloses a cooling core fin air-drying device, relating to the field of industrial manufacturing equipment. It includes a housing, a fan, and left / right roller shutter systems. The housing has stepped protrusions supporting the cooling core, and the bottom fan creates negative pressure inside the housing. Its innovation lies in the fact that both the left and right roller shutter systems use synchronous belt transmission mechanisms to precisely pull the moving ends of the roller shutters horizontally. Each transmission mechanism is driven by a geared motor to drive the main drive shaft, which, through an active synchronous pulley, a driven synchronous belt, and a synchronous belt, drives the fixed block and roller shutter fixed on the synchronous belt to move. This utility model uses a PLC to control the synchronous operation of the motors on both sides, so that the moving ends of the roller shutters on both sides can form a "drying window" of a specific width and can scan and move synchronously. This achieves global air drying of the cooling core, followed by local scanning-style enhanced air drying without dead angles, which has the advantages of high efficiency, uniformity, high degree of automation, and high reliability.

Description

Technical Field

[0001] This utility model relates to the field of industrial manufacturing equipment technology, and in particular to a cooler core fin drying device. Background Technology

[0002] Coolers are key components in many large industrial equipment, and their performance affects the safe and stable operation of the main equipment. During the manufacturing process, the cooler core needs to undergo an airtightness test (such as a water test) to ensure that it is leak-free. This process can result in a large amount of moisture remaining in the dense gaps between the fins inside the core. If this residual moisture is not completely dried, it may cause a series of serious quality problems after the whole machine is assembled, such as internal circuit short circuits, corrosion of metal parts, and reduced cooling efficiency.

[0003] Currently, common drying methods mainly include natural air drying, oven drying, and positive pressure air drying. Natural air drying takes a very long time and is inefficient, making it impossible to meet production rhythm. Oven drying consumes a lot of energy and may pose a risk of thermal aging to non-metallic parts inside the cooler. Positive pressure air drying uses a fan to blow on the surface of the core, but due to the complex structure of the fins, the airflow is prone to rebound and form turbulence, which has limited effect on removing moisture deep in the gaps between the fins, resulting in drying dead zones and uneven results.

[0004] Therefore, there is an urgent need for a dedicated air-drying device that is efficient, uniform, reliable, and has low energy consumption to solve the problem of completely removing residual moisture after the airtightness test of the cooler core. Utility Model Content

[0035] The left synchronous belt 12 transmission mechanism has two sets, which are used to pull the front and rear ends of the left end beam 9 respectively; the right synchronous belt 21 transmission mechanism has two sets, which are used to pull the front and rear ends of the right end beam 18 respectively.

[0036] The left-side geared motor 14 and the right-side geared motor 23 are both electrically connected to a PLC controller. The PLC controller is programmed to control the left-side geared motor 14 and the right-side geared motor 23 to run synchronously, so that the movable ends of the left-side roller shutter 8 and the right-side roller shutter 17 can maintain a set distance and move synchronously towards or in opposite directions.

[0037] In actual manufacturing, the equipment mainly consists of a housing 1, a fan system 2, a left-side roller shutter system, and a right-side roller shutter system. The housing 1 is welded from 6mm and 4mm thick steel plates to form a sealed cavity. A circular air inlet is opened at the bottom of the housing, and a metal air inlet grille 3 is installed. An exhaust outlet is opened on the side wall of the housing 1, and a metal exhaust grille 4 is installed. A stepped protrusion 5 is placed on the inner side of the housing 1 to support the cooler core. Ultra-high molecular weight polyethylene guide rails 6 are installed on the left and right sides of the upper surface of the housing 1; these rails are wear-resistant and have a low coefficient of friction. The machine system 2 includes two high-volume centrifugal fans, installed side-by-side at the bottom of the housing 1, with their air inlets facing the air inlet grille 3 and their exhaust outlets facing the exhaust grille 4. Upon startup, a strong negative pressure is created within the housing 11. The core of the left-side roller shutter system lies in its synchronous belt drive mechanism. The left-side roller shaft 7 is mounted on the left side of the housing 1 via bearing seats. A left-side driving synchronous pulley 10 is installed at each end of the left-side roller shaft 7. The first rotating shaft 15 is installed on the right side of the housing 1, with a left-side driven synchronous pulley 11 installed at each end of the first rotating shaft 15. A left synchronous belt 12 connects the left driving synchronous pulley 10 and the left driven synchronous pulley 11. The left geared motor 14 drives the left shaft to rotate, thereby driving the two left synchronous belts 12 to move synchronously. Each of the two left synchronous belts 12 is equipped with a left fixed block 13, which is fastened to the left end beam 9 of the movable end of the left roller blind 8. Therefore, by controlling the rotation of the left geared motor 14, the left roller blind 8 can be precisely pulled horizontally by the left synchronous belt 12. The left roller shaft 7 provides the functions of storing the left roller blind 8 and retracting the spring. The right roller blind system is a mirror image of the left system, with the same components and connections. It is driven independently by the right geared motor 23. A PLC controller is installed in the equipment's electrical control box to control the synchronous operation of the left geared motor 14 and the right geared motor 23 through programming.

[0038] Working Process: Initially, both roller shutters are fully retracted, and the wet cooler core is placed on the stepped protrusion 5. The fan system 2 is started to perform global negative pressure drying for 10-15 minutes. Subsequently, the PLC controller starts the local drying program: controlling the left and right geared motors to rotate synchronously, releasing the left roller shutter 8 and the right roller shutter 17, so that their moving ends move towards each other to the leftmost end of the housing 1, so that the left end beam 9 and the right end beam 18 maintain a 20cm gap. The negative pressure tightly adheres the roller shutters to the surface of the cooler core, forming a 20cm wide "drying window". High-speed airflow is concentrated through this window to perform strong drying on this area for 2 minutes. After 2 minutes, the PLC issues a command, and the two geared motors rotate synchronously again, pulling the moving ends of the roller shutters on both sides to move synchronously to the right by 10cm to perform strong drying on the next section. This cycle continues until the "drying window" scans from the leftmost end to the rightmost end, completing the intensive drying of the entire cooler core. Finally, the roller shutters are retracted, the fan stops, and the completely dry cooler core is taken out.

[0039] Any aspects of this utility model not described in detail are well-known technologies to those skilled in the art.

[0040] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
