Detailed Description
Preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely illustrative, exemplary, and should not be construed as limiting the scope of the application.
First, terms of top, bottom, upward, downward, and the like are defined with respect to directions in the drawings. These orientations are relative concepts and will therefore vary depending on the location and state in which they are located. These and other directional terms should not be construed as limiting.
Furthermore, it should also be noted that, for any individual feature described or implied in the embodiments herein or any individual feature shown or implied in the figures, these features (or their equivalents) can be combined further to obtain other embodiments not directly mentioned herein.
It should be noted that in different drawings, the same reference numerals indicate the same or substantially the same components.
The present application relates to a compressor housing. In one embodiment, the compressor housing is installed in a refrigeration circuit. In one embodiment, the refrigeration circuit is a refrigeration circuit for a vehicle air conditioning system. For vehicle air conditioning systems, the installation space available on the vehicle is limited, the driving power that the vehicle can provide is also limited, and there is also a significant need for weight saving of the vehicle. Therefore, the compressor housing of the vehicle refrigeration circuit is required in terms of sealing effect, structural strength, occupied space, weight, and the like.
The compressor housing may include one or more structural members. In one embodiment, the compressor housing is integrally formed and includes only a single component. In another embodiment, the compressor housing may be formed from multiple segments, and each segment is constructed as a separately manufactured component, and then assembled together. The compressor housing may define a cavity located therein and at least one opening. In one embodiment, the opening is in communication with the cavity. In addition, the compressor housing may also include a cover, such as two covers. Each cover may be separately configured to fit the opening and be selectively attachable to the opening. The cavity may be configured to be sealed and may contain a refrigerant. The refrigerant puts new demands on the sealing properties of the cavity and the reliability of the weld.
Fig. 1 is a cross-sectional view of a portion of a compressor housing for a refrigeration circuit according to one embodiment of the application. The components 210 and 220 may represent one of the following: structural members, covers, etc. that make up the compressor housing. Therefore, the connection relationship and the operation member described below can be applied to: structural members, cover members, and the like. The embodiment shown in fig. 1 is intended to schematically illustrate the connection between the components of the compressor housing. As shown, the ends of the members 210 and 220 that are adjacent to each other are shown as being generally planar. However, it is easily understood that the ends of the parts 210 and 220 may be configured to have other shapes, and the effect of the present application can be achieved as long as the ends of the parts 210 and 220 are matched in shape with each other. In one embodiment, the portions of the compressor housing represented by components 210 and 220 may be made of the same material, such as an aluminum alloy or the like. The components 210 and 220 may be formed by a variety of processes including, but not limited to, die casting, and the like. The interface between the components 210 and 220 may have a generally closed-shaped profile, such as circular, oval, rounded rectangular, combinations thereof, or the like. Furthermore, the components 210 and 220 in fig. 1 to 5 are not shown completely, but are shown partly schematically in the form of cut-lines.
Welding intermediary 100 may be disposed between components 210 and 220. In one embodiment, both sides of welding intermediary 100 may be shaped to fit the ends of components 210 and 220. Furthermore, the welding intermediary 100 may also be configured with a profile having a closed shape so as to be distributed along the interface between the parts 210 and 220, such that the welding intermediary 100 is located between the whole of the parts 210 and 220. In one embodiment, the welding intermediary 100 may be configured as a plate and may have a contour of a closed shape, such as a circle, oval, rounded rectangle, or a combination thereof, or the like. As shown, the welding intermediary 100 may have a first thickness T1. The first thickness T1 may be, for example, a thickness in the axial direction A-A of the compressor housing. The first thickness T1 may be between 0.5 mm and 5mm, for example, may be 0.5 mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5 mm, 5mm, etc. Furthermore, the first thickness T1 may be set to be substantially smaller than the dimensions of the components 210 and 220 in the axial direction A-A. In one embodiment, the welding intermediary 100 may be positioned between two structural members, or between one structural member and one cover.
Intermediate weldment 100 may be made of the same or different materials as components 210 and 220. In one embodiment, the intermediate weldment 100 may be made of an aluminum alloy. In one embodiment, all of the components comprising the compressor housing may be made of the same material. Although different cross-hatching is used in fig. 1-5 to distinguish intermediate weld 100 and components 210 and 220, it is readily understood that different cross-hatching is not intended to represent different materials.
Fig. 2 is a cross-sectional view of a portion of a compressor housing for a refrigeration circuit according to another embodiment of the application. The intermediate weldment 100' is another embodiment of the intermediate weldment 100. In the illustrated embodiment, the intermediate weldment 100' has a greater dimension in the radial direction R-R than the components 210 and 220. Specifically, intermediate weld 100' is flush with the outer surfaces of components 210 and 220 in radial direction R-R and protrudes toward the cavity relative to the inner surfaces of components 210 and 220.
Fig. 3 is a cross-sectional view of the embodiment of fig. 1 at a first step during manufacture, fig. 4 is a cross-sectional view of the embodiment of fig. 1 at a second step during manufacture, and fig. 5 is a cross-sectional view of the embodiment of fig. 1 at a third step during manufacture. In a first step shown in fig. 3, opposing forces F1 and F2 are applied to the components 210 and 220, and thus, the components 210 and 220 clamp the intermediate weldment 100. Although the illustrated embodiment shows that there is still some clearance between the intermediate weldment 100 and the components 210 and 220, it is readily understood that the clearance is shown for illustrative purposes only and that the intermediate weldment 100 may be in contact with the components 210 and 220.
In the second step shown in fig. 4, the laser 300 is directed at the outer surface of the intermediate weldment 100 in the radial direction R-R and emits laser light B toward the intermediate weldment 100. Laser 300 may be any suitable laser light source and laser B may have a corresponding wavelength and energy intensity. Laser light B impinges on a portion of intermediate weld 100 and at least partially affects a portion of components 210 and 220. A portion of intermediate weld 100 and a portion of components 210 and 220 may be melted by the laser.
In a third step shown in fig. 5, a portion of intermediate weldment 100 and a portion of members 210 and 220 are bonded together after being melted by heat and then solidified as a unit as the temperature decreases, thereby forming welded body 110. The weld body 110 may be formed across a portion of the intermediate weld 100 and a portion of the components 210 and 220, and may extend in the radial direction R-R from an outer surface of the intermediate weld 100 toward the cavity, in other words, the weld body 110 may be located at the periphery or outer periphery of the weld intermediate 100. In one embodiment, the weld body 110 may extend to the vicinity of the cavity. In the illustrated embodiment, the weld body 110 extends in the radial direction R-R only to a portion of the width of the intermediate weld 100.
It is readily understood that the compressor housing may be configured to have a generally circular cross-section, and that the laser 300 may be disposed outside the compressor housing. During welding, the compressor housing may be rotated about its axis of symmetry and the laser 300 may remain stationary. In one embodiment, the compressor housing may remain stationary and the laser 300 may rotate about the compressor housing. The welding may be performed around the entire circumference of the compressor housing such that the outer surface of the intermediate welding member 100 integrally forms the welding body 110. The weld 110 will provide sealing and attachment properties to the compressor housing and eliminate the need to use additional seals and fasteners. Accordingly, the compressor housing and the method of manufacturing the same of the present application provide a simplified manufacturing process and reduce manufacturing costs.
The compressor shell for the refrigeration loop and the method for manufacturing the compressor shell have the advantages of simple structure, convenience in manufacturing, reliable sealing performance and the like. By adopting the compressor shell and the manufacturing method thereof, the sealing effect of the compressor is improved, and the manufacturing process is simplified.
The present specification discloses the present application with reference to the accompanying drawings and also enables one skilled in the art to practice the application, including making and using any devices or systems, selecting suitable materials, and using any incorporated methods. The scope of the application is defined by the claims and encompasses other examples that will occur to those skilled in the art.
