Description

Technical Field

[0001] This utility model belongs to the technical field of heat exchanger processing equipment, specifically relating to a device for assembling the core of a plate-fin heat exchanger. Background Technology

[0002] In the heat exchanger manufacturing process, the core is its core component, and its processing quality directly affects the overall performance of the heat exchanger. Assembly and brazing are two crucial processes in the core production process. Quality control in the assembly process is particularly critical, especially regarding the alignment accuracy of the core's ends and sides, which directly impacts the stability and welding quality of subsequent brazing processes. Traditional assembly methods typically rely on manual operation, requiring operators to manually align and secure the various parts of the core. This method is not only labor-intensive and inefficient, but also prone to errors and subjectivity, making it difficult to guarantee alignment accuracy. This, in turn, affects the uniformity and sealing of brazed joints, and can even lead to product leaks and other quality problems.

[0003] To improve assembly accuracy and efficiency, some companies have begun to introduce mechanized or semi-automatic assembly equipment. For example, existing technologies disclose clamping devices for heat exchanger core assembly, which clamp and fix the core through a lower clamping mechanism located at the top of a gantry frame. However, the gantry frames in existing technologies are usually fixed designs with non-adjustable spatial layouts, which makes it easy for other equipment to interfere with the lower clamping device during actual installation and use, affecting its normal operation.

Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0018] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0019] According to an embodiment of this utility model, a device for assembling a plate-fin heat exchanger core is provided. Please refer to [link to relevant documentation]. Figures 1 to 3The system includes a lifting frame 100 and a gantry frame 200. A packing strap assembly 800 is provided on the rear side of the lifting frame 100, and a gantry frame 200 is provided on its front side. A platform seat 170 is provided on the rear side of the gantry frame 200. The platform seat 170 is slidably connected to the lifting frame 100. A lifting element 900 is provided on the lifting frame 100 to drive the platform seat 170 and the gantry frame 200 to rise and fall.

[0020] It is understandable that both the gantry frame 200 and the platform base 170 are arranged vertically, and the platform base 170 is connected to the rear side of the gantry frame 200 (the side closest to the strapping assembly 800), meaning that the platform base 170 and the gantry frame 200 are integrated into one unit. The lifting element 900 extends and retracts vertically, and during its extension and retraction, it drives the platform base 170 and the gantry frame 200 to rise and fall, allowing for adjustment of the relative position of the gantry frame 200 and the lifting frame 100 at any time, avoiding interference and improving versatility and flexibility.

[0021] Specifically, the lifting element 900 can be a hydraulic cylinder or a pneumatic cylinder.

[0022] In this embodiment, a device for assembling a plate-fin heat exchanger core is described, please refer to... Figures 1 to 3 The lifting frame 100 includes a base plate 102 and two oppositely arranged side plates 101. The packing strap assembly 800 is disposed above the base plate 102. A transverse connecting beam 103 and a longitudinal connecting beam 104 are connected between the two side plates 101. A guide assembly is provided between the longitudinal connecting beam 104 and the platform base 170.

[0023] Understandably, the side uprights 101 are designed in an inverted T-shape, meaning their bottom width is greater than their top width, to improve stability. The bottom of the base plate 102 is connected to the side uprights 101. A transverse connecting beam 103 is positioned between the two side uprights 101, and a longitudinal connecting beam 104 connects the transverse connecting beam 103 to the base plate 102. The fixed end of the lifting element 900 is connected to the base plate 102.

[0024] Specifically, weight-reducing holes can be provided on the side plate 101 to reduce weight.

[0025] Specifically, the strapping assembly 800 includes strapping and a strapping rack, the strapping rack being mounted on the base plate 102, and the strapping being installed in the strapping rack via a disc.

[0026] Specifically, the guide component can adopt a combination structure of slide rail and slider.

[0027] In this embodiment, a device for assembling a plate-fin heat exchanger core is described, please refer to... Figures 1 to 3A front connecting beam 105 is also connected between the two side uprights 101, and the front connecting beam 105 and the base plate 102 form a space to accommodate the gantry frame 200. Through this structure, the gantry frame 200 can be embedded as an independent module in the device, which is beneficial for later maintenance, replacement, or adjustment. At the same time, it can effectively reduce interference from external equipment, leave operating space for other equipment, and improve the overall layout rationality.

[0028] In this embodiment, a device for assembling a plate-fin heat exchanger core is described, please refer to... Figures 1 to 4 The gantry frame 200 includes an upper connecting beam 201 and a lower connecting beam 202. A guide shaft 203 is connected between the upper connecting beam 201 and the lower connecting beam 202. An upper pressing assembly is slidably connected to the guide shaft 203. A first pressing element 300 is provided on the upper connecting beam 201. The movable end of the first pressing element 300 is connected to the upper pressing assembly and is used to drive the upper pressing assembly to slide along the guide shaft 203, thereby realizing the pressing or loosening of the plate-fin heat exchanger core.

[0029] Understandably, the upper connecting beam 201 is located at the top of the gantry frame 200, and the lower connecting beam 202 is located at the bottom of the gantry frame 200. The guide shaft 203 connects the ends of the upper connecting beam 201 and the lower connecting beam 202 respectively, providing a guide path for the upper clamping assembly, ensuring that it has good straightness and stability during its up and down movement, and avoiding deviation or jamming.

[0030] Specifically, the first clamping element 300 can be a hydraulic cylinder or a pneumatic cylinder.

[0031] In this embodiment, a device for assembling a plate-fin heat exchanger core is described, please refer to... Figures 1 to 7 The upper clamping assembly includes a clamping beam 400 and several clamping block units 500. The clamping beam 400 has an inner cavity, in which a guide rail 120 is provided. The several clamping block units 500 are slidably disposed on the guide rail 120.

[0032] Furthermore, a bushing is provided on the clamping beam 400, and the guide shaft 203 passes through the bushing, so that the clamping beam 400 and the guide shaft 203 can be slidably connected.

[0033] Furthermore, a lead screw and slide assembly 110 is provided at the end of the clamping beam 400. The lead screw and slide assembly 110 includes a lead screw 1101, a slide 1102, and a lead screw nut 1103. The slide 1102 is arranged vertically and connected to the clamping beam 400. The lead screw 1101 is rotatably connected to the slide 1102. The lead screw nut 1103 is threadedly matched with the lead screw 1101. A sensor switch is provided on the lead screw nut 1103 to monitor the position of the clamping beam 400. It is understood that the position height of the sensor switch can be adjusted by rotating the lead screw 1101. As a limit detection device, the sensor switch triggers a signal when the clamping beam 400 reaches its limit position, preventing the device from overtravel and providing safety protection.

[0034] In this embodiment, a device for assembling a plate-fin heat exchanger core is described, please refer to... Figures 1 to 7 A connecting block 150 is provided on the cavity wall of the inner cavity, a guide rail pad 130 is provided above the guide rail 120, and a second pressing element 140 is provided between the connecting block 150 and the guide rail pad 130.

[0035] It is understandable that the connection between the guide rail 120 and the pressure beam 400 is established through the synergistic effect of the guide rail pad 130, the second pressing element 140 and the connecting block 150, thereby improving the stability of the guide rail 120. During operation, the vertical position of the gantry frame 200 is adjusted using the lifting element 900 to avoid interference with other equipment. The first clamping element 300 is activated, and the clamping block unit 500 moves downward with the clamping beam 400 until it abuts against the heat exchanger core. After that, the second clamping element 140 extends, and the clamping block unit 500 further clamps the heat exchanger core.

[0036] Specifically, a limit block 160 is provided on the cavity wall to limit the extreme position of the guide rail 120.

[0037] Specifically, the second clamping element 140 can be a hydraulic cylinder or a pneumatic cylinder.

[0038] In this embodiment, a device for assembling a plate-fin heat exchanger core is described, please refer to... Figures 1 to 7 The clamping block unit 500 includes two clamping blocks 501 arranged opposite to each other. The top of the two clamping blocks 501 is connected to a clamping block seat 502. The clamping block seat 502 is slidably connected to the guide rail 120 through a connecting seat 504. The bottom of the clamping block 501 is provided with a clamping block plate 503.

[0039] Understandably, the two clamping blocks 501 are arranged opposite each other to form a symmetrical structure, which allows for simultaneous clamping of the heat exchanger core, avoiding uneven loading or deformation caused by clamping on one side. The clamping block seat 502 is slidably connected to the guide rail 120 through the connecting seat 504, enabling the clamping block unit 500 to move along the guide rail 120, facilitating the adjustment of the spacing between adjacent clamping block units 500 according to the specifications of the heat exchanger core. The clamping block pressure plate 503 is located at the bottom of the clamping block 501 and is used to contact the surface of the heat exchanger core, playing a role in buffering, anti-slip, and protecting the surface of the heat exchanger core, thereby improving the stability and safety of clamping.

[0040] In this embodiment, a device for assembling a plate-fin heat exchanger core is described, please refer to... Figures 1 to 7 The pressing block unit 500 also includes a fixed block 505 and a movable block 506. The fixed block 505 is connected to the pressing block seat 502. The fixed block 505 and the movable block 506 are located on different sides of the guide rail 120, and a locking member 507 is connected between them.

[0041] Understandably, the fixed block 505 and the movable block 506 are located on both sides of the guide rail 120, forming a cross-rail clamping structure, which allows the clamping block unit 500 to be stably installed on the guide rail 120, preventing displacement or detachment during sliding. The fixed block 505 and the movable block 506 are connected by the locking member 507. When the locking member 507 is released, the position of the clamping block unit 500 can be adjusted by sliding along the guide rail 120. After locking, it is rigidly fixed to prevent displacement during operation.

[0042] Specifically, the locking element 507 can be made of bolts.

[0043] In this embodiment, a device for assembling a plate-fin heat exchanger core is described, please refer to... Figures 1 to 7 The lower connecting beam 202 is provided with a left clamping component 600 and a right clamping component 700 opposite to each other, and the distance between the left clamping component 600 and the right clamping component 700 is adjustable.

[0044] Understandably, the left clamping assembly 600 and the right clamping assembly 700 are respectively connected to a double-ended ball screw drive. Rotating the handwheel drives the left clamping assembly 600 and the right clamping assembly 700 to move synchronously towards each other, clamping and positioning the left and right ends of the heat exchanger core.
