Description

Technical Field

[0001] The utility model relates to the technical field of air tightness detection, in particular to an air tightness detection device for a plate heat exchanger. Background Art

[0002] The plate heat exchanger is composed of stamped concave-convex stainless steel plates. The concave-convex patterns between two adjacent plates are 180 degrees relative to each other. Therefore, the concave-convex ridges between the two plates of the plate heat exchanger form staggered contact points. After the contact points are combined by vacuum welding, a high-pressure resistant staggered flow structure of the plate heat exchanger is formed. These staggered flow structures cause strong turbulence of the cold and hot fluids in the plate heat exchanger to achieve a high heat exchange effect. According to the "Plate Heat Exchanger Air Tightness Detection Device" provided by China Patent Authorization Announcement No. CN216869903U, through the setting of the moving plate, the first L-shaped plate, the second L-shaped plate, the motor, the threaded rod, the slide plate, the mounting plate, the electric telescopic rod and the push plate, the motor drives the threaded rod to move. The rod rotates to move the slide plate upwards. After the plate heat exchanger is moved to a suitable position, the electric telescopic rod drives the push plate to push the plate heat exchanger. The plate heat exchanger slides to the upper end of the moving plate and moves to the upper end of the support plate. The plate heat exchanger can be moved to the detection position autonomously, which reduces the workload of the staff and improves the detection efficiency. However, the plate heat exchanger is lifted to a corresponding height and assembled with the detection box by the cooperation of multiple transmission mechanisms. Due to the coordinated use of multiple transmission mechanisms, it takes a certain amount of time, which affects the airtight detection time of the plate heat exchanger, increases the detection time of the workers, reduces the detection speed of the product, and the unstable lifting mechanism is prone to cause the product to fall during the transmission process.
