Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchange equipment, and particularly relates to an oxygen medium double-shell-side high-efficiency supercharger aftercooler. Background Technique

[0002] The existing similar compressor aftercoolers generally adopt a single-shell-side structure. With high gas pressure and low medium flow velocity, the heat exchange effect is poor and the resistance exceeds the standard. In addition, part of the cooler structure adopts a fixed tube sheet type, and the outside of the core cannot be cleaned, which affects the heat exchange effect and service life. For the non-fixed tube sheet type, due to many sealing surfaces between the heat exchanger core and the cylinder body, leakage is likely to occur.

[0003] Therefore, an oxygen medium double-shell-side high-efficiency supercharger aftercooler is designed to overcome the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies existing in the prior art, and to provide an oxygen medium double-shell-side high-efficiency supercharger aftercooler with simple and reasonable structure, convenient installation and use, good heat exchange effect, good sealing performance and anti-leakage.

Water flows from the water inlet pipe into the core through the core inlet, flows through the whole core, and then flows out through the core outlet and the water outlet pipe in sequence.

[0022] The structure of the present utility model that the core and the rear water cover are integrally placed in the housing enables there to be only one sealing surface between the core and the housing, and achieves the intrinsic safety of sealing by reducing the number of sealing surfaces.

[0023] Below the core 7, an intake pipe 4 is provided on the cooler housing 1. Above the core 7, an outlet pipe 5 is provided on the cooler housing 1. A horizontally arranged first partition 10 is provided around the outside of the core 7.

After the gas enters the cooler housing 1 through the intake pipe 4 and fills the entire lower region 12, it passes through multiple gaps uniformly arranged on the core 7 and is cooled by the core 7 at the same time. Then it passes through the upper region 11 and the outlet pipe 5 in sequence and is discharged.

[0024] As Figure 2-3 shown, above the core 7, an intake pipe 4 and an outlet pipe 5 arranged horizontally from left to right are respectively provided on the cooler housing 1.

A third partition 15 with an inverted L-shaped structure is provided at the middle position of the core 7. The third partition 15 is used to divide the core 7 into a first tube pass 16 and a second tube pass 17 arranged horizontally from left to right, and separate the first tube pass 16 from the outlet pipe 5. The space between the first partition 10, the second partition 14 and the intake pipe 4 is the first inlet buffer space 18. The space between the inverted L-shaped third partition 15, the first partition 10 and the first tube pass 16 is the second inlet buffer space 19. The space between the third partition 15, the second partition 14 and the inner top wall of the cooler housing 1 is the outlet buffer space 20. After the gas flows through the first inlet buffer space 18, it enters the second inlet buffer space 19 through the notch 13, first passes through the gaps provided in the first tube pass 16 and is cooled by the first tube pass 16.

[0026] The utility model adopts a double O-ring structure, with a leakage collection groove and a guiding hole arranged between the two O-rings. The leaked medium is led out through a conduit to the guiding hole on the front tube sheet of the core and then out of the shell, so as to improve the sealing reliability. At the same time, the effectiveness of the internal sealing surface can be monitored by whether there is medium leakage. For the sealing surfaces between the external front water cover and the core, and between the core and the shell, which are all exposed externally, the sealing condition can be effectively monitored.

[0027] The design features of the utility model are as follows:

[0028] 1. By adopting a multi-pass countercurrent structure in combination with structural adjustment to increase the medium flow rate and achieve the purpose of improving the heat exchange effect;
