Description

Technical Field

[0001] This utility model relates to the field of air intake pipe technology, and in particular to an air intake pipe for magnetic levitation refrigeration units. Background Technology

[0002] In magnetic levitation refrigeration units, the suction pipe is a key channel for refrigerant gas to enter the compressor, and its structural design directly affects the gas flow efficiency and the stability of unit operation.

[0003] In existing technologies, suction pipes are often made up of straight pipes, equal-diameter elbows, and steel reducers. There is usually a significant diameter change at the position of the steel reducer, which increases the flow resistance and aerodynamic noise of the refrigerant medium inside the suction pipe. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an air intake pipe for magnetic levitation refrigeration units. This air intake pipe can effectively reduce pressure loss and aerodynamic noise.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An air intake pipe for a magnetic levitation refrigeration unit includes a reducing elbow, with a first adapter and a second adapter at each end of the reducing elbow, the first adapter having a larger diameter than the second adapter. The reducing elbow has pressure and temperature measuring holes on its sidewalls, and an external control system can be connected to these holes via piping.

[0007] Furthermore, the thickness of the sidewall of the reducing elbow is greater than or equal to 4 mm and less than or equal to 8 mm.

[0008] Furthermore, both the first and second adapters are flanges, and the first and second adapters are welded to or integrally formed with the reducing elbow, respectively.

[0009] The aforementioned suction pipe for the magnetic levitation refrigeration unit has pressure and temperature measuring holes set on the reducing bend, which facilitates the external control system to obtain the temperature and pressure parameters inside the suction pipe in real time, thus enhancing the operation monitoring capability. By adopting the reducing structure, the flow resistance of the refrigerant medium inside the suction pipe is reduced, the flow efficiency of the refrigerant medium is improved, and the aerodynamic noise is reduced.

[0010] Figure 1 This is a schematic diagram of the suction tube provided by this utility model. Detailed Implementation

[0011] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0012] like Figure 1 As shown, this application provides an intake pipe for a magnetic levitation refrigeration unit. The intake pipe includes a reducing elbow 1. Compared with the combination of a straight pipe and a bend, the reducing elbow 1 reduces the abrupt change in the internal diameter, improves the refrigerant medium flow efficiency, and reduces aerodynamic noise, which helps to improve the overall performance of the system.

[0013] The reducing elbow 1 has a first adapter 2 and a second adapter 3 at each end, with the diameter of the first adapter 2 being larger than the diameter of the second adapter 3. The reducing elbow 1 has a pressure measuring hole 4 and a temperature measuring hole 5 on its side wall. An external control system can be connected to the pressure measuring hole 4 and temperature measuring hole 5 via piping. The arrangement of the pressure measuring hole 4 and temperature measuring hole 5 facilitates dynamic monitoring of the refrigerant medium state, improving the safety and controllability of the system operation.

[0014] Furthermore, the thickness of the sidewall of the reducing elbow 1 is greater than or equal to 4 mm and less than or equal to 8 mm.

[0015] Furthermore, both the first adapter 2 and the second adapter 3 are flanged components to improve the ease of installation of the reducing elbow 1. The first adapter 2 and the second adapter 3 are welded to the reducing elbow 1 respectively. The ability to weld the first adapter 2 and the second adapter 3 to the reducing elbow 1 separately enhances the connection strength between them. Depending on actual needs, the first adapter 2 and the second adapter 3 can also be integrally formed with the reducing elbow 1 by casting.

[0016] The above description of embodiments of the present invention, through which those skilled in the art are able to implement or use the present invention, will be readily apparent to those skilled in the art. Various modifications to these embodiments will be readily apparent to those skilled in the art. The general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novelty disclosed herein.
