Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a tube-fin type square heat exchanger. Background Art

[0002] Tube-fin heat exchangers are widely used in industrial production, such as the refrigeration industry, due to their compact structure, high efficiency, durability, and simple manufacturing process, and have become the main heat exchange components.

[0003] For example, the utility model with application number 201720734733.7 discloses a tube-fin heat exchanger, in which high-temperature coolant is injected into a circular tube, and low-temperature air flows in parallel fin channels. The air exchanges heat with the coolant in the tube when passing through the fin channels, and the air flows out of the heat exchanger after the temperature rises and becomes high-temperature air. At the same time, the coolant temperature drops and flows back to the flow channel of the component that needs to be cooled. Due to the special structure of the fin body, the high-temperature coolant can fully exchange heat with the low-temperature air in the fin channel when flowing through the circular tube, which can greatly improve the heat exchange efficiency. At the same time, under the same heat exchange power conditions, the volume of the heat exchanger can be greatly reduced, reducing the manufacturing cost.

[0004] Similar to the above application, there are still some shortcomings:

[0005] This type of tube-fin heat exchanger can greatly reduce the volume of the heat exchanger and reduce the manufacturing cost under the condition of the same heat exchange power. However, the tube-fin heat exchanger is not convenient for splicing the outer shell frame. Generally, bolts and other components are used to splice and fix the heat exchanger in sequence, which reduces the efficiency of splicing and fixing and is very inconvenient to use. In addition, the pipeline stability of the tube-fin heat exchanger is poor, which is not conducive to improving the heat exchange efficiency.

[0006] Therefore, a tube-fin square heat exchanger is designed to optimize the above problems. Utility Model Content

[0007] The main purpose of the utility model is to provide a tube-fin square heat exchanger to solve the relevant technical problems raised in the above background technology.

[0008] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0014] Preferably: A reinforcement layer is arranged on the inner side wall of the through hole, and the reinforcement layer is a rubber layer.

Until the C-shaped blocks at the bottom of the splicing plate are aligned with the through holes and inserted into the through holes, and at the same time, the splicing plates are respectively attached to the top and bottom of the side plates. Then, rotate the rotating block to make the adjusting rod rotate, thereby driving the slider and the C-shaped block to move horizontally until the inner wall of the C-shaped block fits against the inner side wall of the through hole.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] To make the technical solutions of the present utility model clearer and more definite for those skilled in the art, the present utility model will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present utility model are not limited thereto.

[0022] Embodiment 1

[0023] As Figure 1-Figure 3As shown in the figure, this embodiment provides a finned tube square heat exchanger, which includes side plates 1. Inside the side plates 1, heat exchange tubes 2 are installed. Fins 10 are evenly arranged outside the heat exchange tubes 2. At the top and bottom of the side plates 1, splicing plates 4 are installed. On one side of each side plate 1, fixing plates 3 are symmetrically arranged. Through holes 9 are formed in the fixing plates 3. On the sides of the splicing plates 4 close to each other, adjusting rods 5 are rotatably installed. At the middle position of the adjusting rods 5, rotating blocks 6 are fixed. On the outside of the adjusting rods 5, sliders 7 are symmetrically arranged. At the bottom of the sliders 7, U-shaped blocks 8 are fixed. Installation holes 11 are symmetrically formed on the outside of the side plates 1 and the outside of the splicing plates 4. On the inner side walls of the side plates 1, arc-shaped plates 12 are evenly fixed. On the arc-shaped plates 12, limiting rods 13 are threadedly connected. The ends of the limiting rods 13 are rotatably connected to limiting plates 14, and the inner side walls of the limiting plates 14 are movably connected to the outside of the heat exchange tubes 2.

[0024] By the combined use of the side plates 1, heat exchange tubes 2, fixing plates 3, splicing plates 4, adjusting rods 5, rotating blocks 6, sliders 7, U-shaped blocks 8, through holes 9, fins 10 and installation holes 11, the upper and lower groups of splicing plates 4 are respectively placed at the top and bottom of the side plates 1 until the U-shaped blocks 8 at the bottom of the splicing plates 4 are aligned with the through holes 9 and inserted into the through holes 9. At the same time, the splicing plates 4 are respectively attached to the top and bottom of the side plates 1. Then, the rotating block 6 is rotated to make the adjusting rod 5 rotate, thereby driving the slider 7 and the U-shaped block 8 to move horizontally until the inner wall of the U-shaped block 8 fits against the inner side wall of the through hole 9. By clamping the through hole 9, the side plates 1 and the splicing plates 4 are spliced, which can more quickly splice and fix the side plates 1 and the splicing plates 4 of the finned tube square heat exchanger, without frequently screwing bolts and other components, achieving the purpose of more convenient operation, thereby improving the convenience of the finned tube square heat exchanger; by the combined use of the arc-shaped plates 12, limiting rods 13 and limiting plates 14, the limiting rods 13 are respectively screwed towards the outside of the bending positions of the heat exchange tubes 2, so that the limiting rods 13 drive the limiting plates 14 at the ends to clamp towards the outside of the bending parts of the heat exchange tubes 2, thereby maintaining the stability of the heat exchange tubes 2 for transporting the medium, improving the heat exchange uniformity, and thus improving the practicability of the finned tube square heat exchanger.

[0025] Embodiment Two

[0026] In this embodiment, as Figure 1-Figure 3 shown, reinforcing pads 15 are fixed on the outside of the splicing plates 4. Reinforcing rings 16 are symmetrically arranged on the reinforcing pads 15, and the outside of the reinforcing rings 16 is engaged with the inner side wall of the installation holes 11.

[0027] By the combined use of the reinforcing pads 15 and the reinforcing rings 16, the reinforcing rings 16 on the reinforcing pads 15 are respectively aligned with the installation holes 11 and engaged inside the installation holes 11. When the splicing plates 4 and the side plates 1 are installed on the outer shell, the reinforcing pads 15 increase the friction with the outer shell, and the reinforcing rings 16 increase the friction between the installation bolts, improving the firmness after installation.

[0028] In this embodiment, an anti-skid ring is arranged on the outer side of the rotating block 6, and anti-skid patterns are evenly arranged on the anti-skid ring.

[0029] The anti-skid ring and the anti-skid pattern increase the friction between the hand and the hand, thereby making it easier to turn the rotating block 6.

[0030] In this embodiment, a toggle block is provided at the end of the limiting rod 13, and the toggle block is an anti-slip toggle block.

[0031] The provision of the anti-slip toggle block facilitates the rotation and use of the limit rod 13, bringing convenience to people's use.

[0032] In this embodiment, a reinforcement layer is provided on the inner side wall of the through hole 9, and the reinforcement layer is a rubber layer.

[0033] The provision of the reinforced rubber layer increases the friction between the through hole 9 and the shaped block 8, thereby improving the stability of the engagement.

[0034] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
