Description

Technical Field

[0001] This utility model relates to the field of equipment heat dissipation technology, specifically a high-efficiency shell-and-tube heat exchanger. Background Technology

[0002] Shell-and-tube heat exchangers are widely used heat exchange devices in many industrial fields such as chemical, petroleum, power, and refrigeration. They mainly consist of a shell, tube bundle, tube sheet, and baffles. Their function is to transfer heat between two fluids at different temperatures, raising or lowering the temperature of one fluid to meet the needs of various processes. For example, in petrochemical production, they are used for heating and cooling crude oil, as well as for the condensation and evaporation of various chemical products; in air conditioning systems, they are used for heat exchange between refrigerant and air or water to achieve cooling or heating functions.

[0003] However, the above application still has certain shortcomings: the above application only emphasizes cooling the inside of the equipment, but lacks heat dissipation for the equipment shell. When the internal components of the equipment are working, the shell of the equipment usually absorbs heat and gets hot. If the shell of the equipment cannot be cooled in time, it will also affect the heat dissipation performance of the equipment. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency shell-and-tube 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 high-efficiency shell-and-tube heat exchanger includes a base, a heat dissipation module mounted on the bottom surface of the base, and shell tubes symmetrically arranged on both sides of the base. The shell tubes have a U-shaped structure, and multiple heat dissipation fins are fixedly installed at equal intervals on the inner wall of the shell tubes. Water pipes are fixedly installed on the multiple heat dissipation fins, and the two water pipes are connected. One side of the water pipe is connected to the input end of the heat dissipation module, and the other side of the water pipe is connected to the output end of the heat dissipation module.

[0007] As a further embodiment of this utility model: both shell tubes are movably arranged, and an adjustment component for adjusting the distance between the two shell tubes is also provided on the base. The adjustment component includes a rotating component, a servo telescopic cylinder, and a push-pull rod. A cavity is opened in the base, and the bottom surface of the shell tube is movably inserted into the cavity. The rotating component is rotatably installed in the cavity, and servo telescopic cylinders are symmetrically fixed on both sides of the rotating component in the cavity. The telescopic end of the servo telescopic cylinder is fixedly connected to one of the shell tubes. The rotating component is connected to the shell tube through the push-pull rod, wherein one end of the push-pull rod is rotatably installed on the rotating component, and the other end is hinged to the side of the shell tube.

[0008] As a further embodiment of this utility model: multiple connecting rods are also installed on the top surfaces of the two shell tubes, with one end of the connecting rod fixed to one of the shell tubes and the other end movably inserted into the other shell tube.

[0009] As a further embodiment of this utility model, the water supply pipes on both sides are connected by a flexible hose.

[0010] As a further embodiment of this utility model, a plurality of movable wheels are also fixedly installed on the bottom surface of the shell tube.

[0011] As a further embodiment of this utility model: multiple cooling fans are fixedly installed on the top surface of the base, and support plates are symmetrically arranged on both sides of the cooling fans on the top surface of the base.

[0012] As a further embodiment of this utility model: multiple rollers are rotatably mounted on the bearing plate.

[0013] As a further embodiment of this utility model: a groove is provided on the base below the bearing plate, a pair of shock absorbers are symmetrically installed between the bottom surface of the bearing plate and the groove, and multiple fixing rods are fixedly installed on the bottom surface of the bearing plate. A baffle is installed on the fixing rod, and a shock-absorbing spring is sleeved on the rod body below the baffle of the fixing rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, by setting up a heat dissipation module, shell tube, heat dissipation fins and water supply pipe, allows multiple heat dissipation fins set inside the shell tubes on both sides to quickly disperse the heat on the equipment shell to the multiple heat dissipation fins when they come into contact with the equipment shell, thereby accelerating the heat dissipation of the equipment shell and improving the heat dissipation efficiency of the equipment. Furthermore, when the heat dissipation module supplies cold water to the water supply pipe, the flowing cold water can quickly cool down the heat dissipation fins, further improving the heat dissipation efficiency of the equipment shell.

[0016] 2. The cooling fan and support plate in this utility model can suspend the bottom surface of the equipment and provide air cooling, further improving the heat dissipation efficiency of the equipment shell. Attached Figure Description

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] Example 1

[0024] Please see Figure 1-4 A high-efficiency shell-and-tube heat exchanger includes a base 1, on the bottom surface of which a heat dissipation module 2 is mounted. Shell-and-tube bodies 3 are symmetrically arranged on both sides of the base 1. The shell-and-tube bodies 3 have a U-shaped structure, and multiple heat dissipation fins 4 are fixedly installed at equal intervals on the inner wall of each shell-and-tube body 3. Water supply pipes 5 are fixedly installed on the multiple heat dissipation fins 4, and the two water supply pipes 5 are connected. One side of the water supply pipe 5 is connected to the input end of the heat dissipation module 2, and the other side is connected to the output end of the heat dissipation module 2. By setting up the heat dissipation module 2, shell-and-tube bodies 3, heat dissipation fins 4, and water supply pipes 5, when the multiple heat dissipation fins 4 inside the shell-and-tube bodies 3 come into contact with the equipment shell, the heat on the equipment shell can be quickly dispersed to the multiple heat dissipation fins 4, accelerating the heat dissipation of the equipment shell and improving the heat dissipation efficiency of the equipment. Furthermore, when the heat dissipation module 2 supplies cold water to the water supply pipes 5, the flowing cold water can quickly cool the heat dissipation fins 4, further improving the heat dissipation efficiency of the equipment shell.

[0025] Specifically, both shell tube bodies 3 on both sides are movably mounted. The base 1 is also equipped with an adjustment assembly for adjusting the distance between the two shell tube bodies 3. The adjustment assembly includes a rotating component 7, a servo telescopic cylinder 8, and a push-pull rod 9. A cavity 6 is opened inside the base 1, and the bottom surface of the shell tube body 3 is movably inserted into the cavity 6. The rotating component 7 is rotatably mounted inside the cavity 6, and servo telescopic cylinders 8 are symmetrically fixed on both sides of the rotating component 7 inside the cavity 6. The telescopic end of the servo telescopic cylinder 8 is fixedly connected to one of the shell tube bodies 3. The rotating component 7 is connected to the shell tube body 3 through the push-pull rod 9. One end of the push-pull rod 9 is rotatably mounted on the rotating component 7, and the other end is hinged to the side of the shell tube body 3. The setting of the adjustment assembly not only allows the heat dissipation fins 4 on both shell tube bodies 3 to make stable contact with the equipment shell, but also allows the device to adapt to equipment of different specifications, which has the advantage of wider applicability.

[0026] Among them, multiple connecting rods 10 are also installed on the top surface of the two shell tube bodies 3. One end of the connecting rod 10 is fixed on one of the shell tube bodies 3, and the other end is movably inserted into the other shell tube body 3. The setting of the connecting rod 10 improves the stability of the relative movement of the shell tube bodies 3.

[0027] Accordingly, in order to adjust the distance between the two shell tube bodies 3, and to ensure that the water supply pipes 5 inside the two shell tube bodies 3 can be stably connected, the water supply pipes 5 on both sides are connected by a flexible hose 11 in this embodiment.

[0028] In addition, multiple movable wheels 12 are fixedly installed on the bottom surface of the shell tube body 3. The movable wheels 12 not only improve the relative motion stability of the shell tube body 3, but also provide a certain support for the bottom surface of the shell tube body 3, making the relative motion of the two shell tube bodies 3 on both sides smoother.

[0029] Example 2

[0030] This embodiment is an improvement on embodiment 1, specifically as follows:

[0031] Please see Figure 1 and Figure 4 The top surface of the base 1 is also fixedly equipped with multiple cooling fans 13, and the top surface of the base 1 is symmetrically provided with support plates 14 on both sides of the cooling fans 13. The arrangement of the cooling fans 13 and the support plates 14 can suspend and air-cool the bottom surface of the equipment, further improving the heat dissipation efficiency of the equipment shell.

[0032] In the process of adjusting the distance between the two shell tube bodies 3, in order to ensure that the heat dissipation fins 4 inside the two shell tube bodies 3 can stably contact the equipment shell, in this embodiment, multiple rollers 15 are rotatably installed on the support plate 14. Specifically, after the heat dissipation fins 4 inside one of the shell tube bodies 3 contact the equipment, as the shell tube body 3 continues to be driven to move, it can push the equipment to slide on the base 1, so that the heat dissipation fins 4 on the other side can contact the equipment shell.

[0033] In addition, a groove is provided on the base 1 below the support plate 14. A pair of shock absorbers 16 are symmetrically installed between the bottom surface of the support plate 14 and the groove. Multiple fixing rods 17 are fixedly installed on the bottom surface of the support plate 14. A baffle 18 is installed on the fixing rod 17. A shock-absorbing spring 19 is sleeved on the rod body of the fixing rod 17 below the baffle 18. The arrangement of the shock absorbers 16, fixing rods 17 and shock-absorbing springs 19 can buffer the vibration generated during the operation of the equipment and reduce noise.

[0034] Working principle and operation process: When using this device, first place the equipment on the two support plates 14 of the base 1. Then, by controlling the extension and retraction of the servo telescopic cylinder 8, the distance between the two shell tube bodies 3 is adjusted so that the heat dissipation fins 4 inside the shell tube body 3 can make stable contact with the two sides of the equipment. During the operation of the equipment, multiple heat dissipation fins 4 can disperse the heat on the outer shell of the equipment, accelerating the heat dissipation efficiency of the outer shell. In addition, the operation of the water cooling module and the cooling fan 13 can also be controlled. When the heat dissipation module 2 delivers cold water to the water pipe 5, the flowing cold water can quickly cool down the heat dissipation fins 4, while the cooling fan 13 can perform air cooling on the bottom surface of the equipment shell, further improving the heat dissipation efficiency of the equipment shell.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
