Air-cooled heat exchanger with shock absorption and noise reduction

Abstract

This utility model discloses a vibration-damping and noise-reducing air-cooled heat exchanger, including a condenser shroud. A fan shroud is fixedly connected to the back of the condenser shroud, and a motor is fixedly connected to the end of the fan shroud away from the condenser shroud. Fixed columns one and two are respectively installed on the left and right sides of the outer wall of the condenser shroud. Connecting pipes are connected to the upper and lower parts of the outer wall of the fixed column two. In this vibration-damping and noise-reducing air-cooled heat exchanger, liquid first enters the first section of pipe through the inlet pipe, then enters the second section of pipe through the first pipe, and then is introduced into another set of second pipes through the third pipe. Finally, after circulation, the liquid enters the outlet pipe and is discharged into the lower connecting pipe, and then enters the upper connecting pipe, thus achieving water circulation. However, the use of a dual-pipeline design results in excessive pressure on the wall surface, causing noise.

Description

Technical Field

[0001] This utility model relates to the field of air-cooled heat exchangers, specifically a vibration-damping and noise-reducing air-cooled heat exchanger. Background Technology

[0002] With the rapid development of industrial technology, air-cooled heat exchangers have been widely used in many fields, such as petrochemicals, power, and metallurgy. Due to their energy-saving, environmentally friendly, and easy-to-maintain advantages, air-cooled heat exchangers are gradually becoming an ideal replacement for water-cooled heat exchangers. However, traditional air-cooled heat exchangers have some significant problems during operation, especially in terms of vibration and noise control. These problems not only affect the stability and service life of the equipment but also have adverse effects on the surrounding environment and the health of workers.

[0003] Air-cooled heat exchangers typically consist of main components such as tube bundles, fans, and frames. During operation, the fan rotates at high speed to drive airflow through the tube bundle, thereby cooling the fluid inside the tubes. However, during the cooling process, the unidirectional flow of the pipes can cause excessive pressure inside the tubes, resulting in noise. Utility Model Content

[0004] The purpose of this invention is to provide a shock-absorbing and noise-reducing air-cooled heat exchanger to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A vibration-damping and noise-reducing air-cooled heat exchanger includes a condenser shroud, a fan shroud fixedly connected to the back of the condenser shroud, a motor fixedly connected to the end of the fan shroud away from the condenser shroud, a first fixed column and a second fixed column respectively installed on the left and right sides of the outer wall of the condenser shroud, connecting pipes connected to the upper and lower parts of the outer wall of the second fixed column, support feet fixedly connected to the bottom of the first fixed column and the second fixed column, a support member fixedly connected to the lower part of the outer wall of the motor, and a front cover installed at the front end of the condenser shroud.

[0007] As a further embodiment of this utility model: a condenser assembly is installed in the inner cavity of the condenser shroud, the condenser assembly includes fins, the number of fins is twenty sets, and tube one and tube three are respectively installed between the twenty sets of fins.

[0008] As a further embodiment of this utility model: both ends of the first pipe and the third pipe are fixedly connected to the second pipe, and the second pipe is used to connect and fix the first pipe and the third pipe.

[0009] As a further embodiment of this utility model: the fin also includes side plates on the sides, and the number of side plates is two sets, with the two sets of side plates having the same structure.

[0010] As a further embodiment of this utility model: the number of tubes two is eight sets, with an inlet tube fixedly connected to one end of the tube two located in the upper part, and an outlet tube fixedly connected to one end of the tube two located in the lower part.

[0011] As a further improvement of this utility model: perforations are provided on both the left and right sides of the outer wall of the fin, and the number of perforations is thirty-two groups, and the thirty-two groups of perforations are evenly distributed.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model connects the upper and lower sections of the liquid flow path to the outer pipe, and guides the liquid into the inlet and outlet pipes connected in two sets of connecting pipes. The liquid first enters the first section of pipe through the inlet pipe, then flows into the second section of pipe through the first section, and then flows into another section of pipe through the third section. Finally, after circulation, the liquid enters the outlet pipe and is discharged into the lower connecting pipe, and then enters the upper connecting pipe, thus achieving water circulation. This design optimizes the structure and makes the design more reasonable, as the double-pipe system can cause excessive pressure and noise on the wall. Attached Figure Description

[0020] Please see Figures 1-4In this embodiment of the utility model, a vibration-damping and noise-reducing air-cooled heat exchanger includes a condenser shroud 1. A fan shroud 3 is fixedly connected to the back of the condenser shroud 1. A motor 2 is fixedly connected to the end of the fan shroud 3 away from the condenser shroud 1. Fixed columns 1-4 and 2-17 are respectively installed on the left and right sides of the outer wall of the condenser shroud 1. Connecting pipes 6 are connected to the upper and lower parts of the outer wall of the 2-17. Support feet 7 are fixedly connected to the bottom of both the fixed columns 1-4 and 2-17. A support member 5 is fixedly connected to the lower part of the outer wall of the motor 2. A front cover 8 is installed at the front end of the condenser shroud 1. When the motor 2 is turned on, it blows air onto the back of the condenser shroud 1, blowing out the cold air from the fins 10.

[0021] A condenser assembly 9 is installed in the inner cavity of the condenser shroud 1. The condenser assembly 9 includes fins 10, and there are twenty sets of fins 10. Tube 11 and tube 3 13 are installed between the twenty sets of fins 10 respectively.

The liquid is connected to the outer pipe through the connecting pipe 6 connected to the upper and lower parts of the back of the fixed column 217, and the liquid is introduced into the inlet pipe 14 and outlet pipe 15 connected in the two sets of connecting pipes 6 respectively. The liquid first enters the pipe 11 through the inlet pipe 14, and then enters the pipe 212 through the pipe 11.

[0023] The fin 10 also includes side plates 16 on the sides. There are two sets of side plates 16, and the two sets of side plates 16 have the same structure. During the circulation, the liquid will absorb heat through the fin 10.

[0024] There are eight sets of pipes 12. One end of the upper pipe 12 is fixedly connected to the inlet pipe 14, and one end of the lower pipe 12 is fixedly connected to the outlet pipe 15. The liquid is introduced into another set of pipes 12 through pipe 3 13. After circulation, the liquid enters the outlet pipe 15 and is discharged into the lower connecting pipe 6. Then it enters the upper connecting pipe 6, thus realizing water circulation.

[0026] The working principle of this utility model is as follows:

[0027] In use, the liquid is connected to the outer pipe through the connecting pipe 6 connected to the upper and lower parts of the back of the fixed column 2 17, and the liquid is introduced into the inlet pipe 14 and outlet pipe 15 connected in the two sets of connecting pipes 6 respectively. The liquid first enters the pipe 11 part through the inlet pipe 14, then enters the pipe 2 12 part through the pipe 11, and then enters the other set of pipe 2 12 through the pipe 3 13. Finally, after circulation, the liquid enters the outlet pipe 15 and is discharged into the lower connecting pipe 6, and then enters the upper connecting pipe 6, thus realizing water circulation.

[0028] During the circulation process, the liquid absorbs heat through the fins 10;
