Abstract
Description
Technical Field
[0001] This application belongs to the field of compressor technology, specifically relating to a compressor housing and a compressor. Background Technology
[0002] A compressor is a mechanical device that reduces the volume of gas and increases its pressure. It transforms low-pressure gas into high-pressure gas through various physical processes and is widely used in automotive and marine engines. However, compressors typically have separate guide vanes installed inside the compressor via O-rings or other elastic components. These O-rings and other elastic components have a relatively short lifespan, affecting the compressor's overall lifespan. Furthermore, the use of O-rings or other elastic components can create gaps behind the guide vane's back plate, leading to leakage of diffused gas and impacting the compressor's efficiency and pressure ratio. Additionally, the installation of O-rings or other elastic components introduces variations to the compressor, affecting its performance consistency. Utility Model Content

[0034] It should also be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0035] See Figure 1The figure is a schematic diagram of a compressor housing provided in an embodiment of this application.
[0036] The compressor housing provided in this application includes the housing of a compressor in a vehicle or ship engine. For example... Figure 1 As shown, the compressor housing provided in this embodiment includes: a pressure shell 200 and an intermediate shell 100;
[0037] A pressure diffusion channel 300 is provided between the pressure shell 200 and the intermediate shell 100;
[0038] The middle shell 100 has a guide vane 101 integrated on the side facing the diffuser channel 300. The guide vane 101 and the middle shell 100 are an integral structure.
[0039] It should be noted that a compressor assembly may be disposed inside the compressor housing in this embodiment. The compressor housing and the compressor assembly together constitute the compressor. The compressor in this embodiment can be applied to marine engines or vehicle engines. The compressor provided in this application can be applied to traditional automobiles or new energy vehicles, and can also be applied to off-road vehicles, such as excavators, etc., which are not limited here. In this embodiment, by integrating the guide vanes onto the intermediate shell, the integrated guide vanes can perform the same function as the guide vanes in related technical solutions, and since the guide vanes and the intermediate shell are an integrated design structure, no other components are needed to fix the guide vanes. Thus, the technical solution of this embodiment can improve the performance of the compressor and extend its service life.
[0040] like Figure 2 As shown in the partial view of region A, in this embodiment of the application, the pressure shell 200 includes an upper expanding surface 201, and the intermediate shell 100 includes a lower expanding surface 102. The upper expanding surface 201 and the lower expanding surface 102 form a diffuser channel 300. In this embodiment of the application, there is a gap between the top surface of the guide vane 101 and the upper expanding surface 201. In practical applications, the width of the gap is less than or equal to 1 mm. As one possible implementation, the width of the gap in this embodiment of the application can be 0.1 mm.
[0041] It should be noted that in this embodiment, the guide vane 101 is integrated into the intermediate shell, and a gap is provided between the guide vane 101 and the upper expanded surface 201, which can improve the compressor performance to a certain extent. Specifically, compared with the technical solution of fixing the guide vane with O-rings, the position of the gap corresponding to the guide vane in the technical solution of this application has a smaller impact on the compressor performance, and can improve the peak efficiency of the compressor by about 0.8 percentage points. In the technical solution of this application, the guide vane is integrated into the intermediate shell. Compared with the technical solution of fixing the guide vane to the intermediate shell with bolts, the guide vane and the intermediate shell can be integrally processed in this application, and there is no gap between the guide vane and the intermediate shell. Using the technical solution of this application, compared with the technical solution of fixing the guide vane with bolts, the compressor efficiency can be improved by about 1 to 1.5 percentage points, and the compressor pressure ratio is higher. It should also be noted that compared with the technical solution of integrating the guide vane 101 into the pressure shell, the technical solution of integrating the guide vane 101 into the intermediate shell in this application improves the compressor performance more significantly.
[0042] like Figure 3 As shown in the intermediate shell 100, a guide vane 101 is integrated on the lower expanded surface 102 of the intermediate shell. The guide vane 101 and the intermediate shell are an integral structure. In practical applications, the intermediate shell with the guide vane can be integrated into the intermediate shell through casting and mechanized machining. This embodiment of the application does not limit this.
[0043] In summary, the embodiments of this application integrate the guide vanes onto the intermediate shell and position the gap between the guide vanes and the upper expansion surface. The structure of the guide vanes and the location of the gap reduce leakage of diffused gas in the compressor, thereby improving compressor performance. Furthermore, since the guide vanes and the intermediate shell are an integrated design, no other components are needed to fix the guide vanes. Thus, on the one hand, the technical solution of this application improves compressor performance; on the other hand, the technical solution of this application omits the elastic components found in related technical solutions, extending the compressor's service life.
[0044] Based on the compressor housing provided in the above embodiments, this application also provides a compressor.
[0045] like Figure 4 As shown, the compressor provided in this application embodiment is applied to vehicle or ship machinery. The compressor includes: a compressor housing 1000 and a compressor assembly 2000 inside the compressor housing 1000.
[0046] The compressor housing includes a pressure shell and an intermediate shell;
[0047] A pressure diffusion channel is provided between the pressure shell and the intermediate shell;
[0048] The middle shell has integrated guide vanes on the side facing the diffuser channel, and the guide vanes and the middle shell are an integral structure.
[0049] As one possible implementation, the pressure shell includes an upper expanding surface, and the intermediate shell includes a lower expanding surface; the upper expanding surface and the lower expanding surface form a pressure diffusion channel.
[0050] As one possible implementation, there is a gap between the top surface of the guide vane and the upper expansion surface.
[0051] As one possible implementation, the width of the gap is less than or equal to 1 mm. As an example, the width of the gap can be 0.1 mm.
[0052] In summary, the embodiments of this application integrate the guide vanes onto the intermediate shell and position the gap between the guide vanes and the upper expanding surface. The structure of the guide vanes and the location of the gap reduce leakage of diffused gas in the compressor, thereby improving compressor performance. Furthermore, since the guide vanes and the intermediate shell are an integrated design, no other components are needed to fix the guide vanes. Thus, on the one hand, the technical solution of this application improves compressor performance; on the other hand, the technical solution of this application omits the elastic components found in related technical solutions, extending the compressor's service life.
