Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
In description of the present utility model, it should be noted that, definition term: with filter axis direction for fore-and-aft direction, " interior ", " outward " are based on position relationship shown in the drawings, term is only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
Consult Fig. 1-Fig. 3, it is an embodiment of the pipe arrangement filter that the utility model proposes, pipe arrangement filter in the present embodiment is used in the refrigeration system of air-conditioning, pipe arrangement filter comprises pipe arrangement 1 and filter 2, and filter 2 is positioned at pipe arrangement 1, filter 2 flows through the cold-producing medium of pipe arrangement 1 for filtering.
In the present embodiment, by being built in pipe arrangement 1 by filter 2, achieving pipe arrangement 1 integrated with filter 2, saving the space that filter 2 takies, some can be avoided because of the puzzlement that filter 2 is oversize, design space is limited, PIPING DESIGN is difficult, be convenient to air conditioning box body miniaturization; And the welding saved for filter, improves production efficiency, decrease welding risk, reduce production cost; Reduce one or more filter kinds simultaneously, realize part-subassemble standard, reduce parts kind, it also avoid the risk that filter is wrongly installed.
In the present embodiment, shown in Figure 1, filter 2 is positioned at the middle part of pipe arrangement 1, and the both ends of pipe arrangement 1 can be bent into the shape of needs as required, adds the flexibility that pipe arrangement 1 is arranged, contributes to the miniaturization of air conditioning box body.Filter 2 is loaded in pipe arrangement 1 by one end of pipe arrangement 1, and filter 2 is pushed to the middle part in pipe arrangement 1; Thus the external diameter of filter 2 needs the internal diameter being less than pipe arrangement 1 certainly, so that filter 2 can be pushed in pipe arrangement 1.
Certainly in other embodiments, also filter 2 can be arranged on the end in pipe arrangement 1 as required, the pipeline section namely pipe arrangement 1 accommodating filter 2 is unyielding, other pipeline sections on pipe arrangement 1 can bend as required, which increase the flexibility that pipe arrangement 1 is arranged, contribute to the miniaturization of air conditioning box body.
In the present embodiment, shown in Figure 3, filter 2 comprises support 21 and fixing filter screen 22 on the stent 21; After pipe arrangement filter is installed to air-conditioning refrigeration system, cold-producing medium flows through from pipe arrangement 1, and certainly, the cold-producing medium flowing through pipe arrangement 1 also flows through filter 2, is filtered; When filter 2 crossed by cold-producing medium, form larger impact to filter 2, thus filter 2 should firmly be fixed in pipe arrangement 1, between support 21 and pipe arrangement 1, be provided with engaging fixing structure; By arranging engaging fixing structure, make fixation between support 21 and pipe arrangement 1.
In the present embodiment, shown in Figure 2, being provided with engaging fixing structure between support 21 and pipe arrangement 1 is: the spaced two inwardly protruded gears in place convex 11 before and after on pipe arrangement 1, and the rear and front end of support 21 is respectively by convex 11 blocks of two place's gears; Such support 21 is limited at the freedom of motion of fore-and-aft direction, and support 21 is fixed in pipe arrangement 21.Keeping off convex 11 is formed by roll extrusion groove on the outer wall of pipe arrangement 1, after filter 2 is in place in pipe arrangement 1, is formed the gear convex 11 of pipe arrangement 11 inside by roll extrusion groove on the outer wall of pipe arrangement 1.In order to increase fastness fixing between support 21 and pipe arrangement 1 further, directly on the outer wall of pipe arrangement 1, groove is enclosed in roll extrusion one, forms the gear convex 11 of a circle like this, that is to say that gear convex 11 is the projection of the annular of pipe arrangement 11 inside.
Certainly, in other embodiments, for the engaging fixing structure that also can arrange other modes between support 21 and pipe arrangement 1.
Shown in Figure 1, when condensing agent flows through filter screen 2, directly impulsive force is applied to filter screen 22, thus also should fixation between filter screen 22 and support 21.In the present embodiment, the confining force arranged between filter screen 22 and support 21 is in the longitudinal direction greater than 200N, and be namely greater than 200N at the confining force of axis direction, the most low energy of filter 2 bears the 200N impulsive force brought from refrigerant flows in other words.
In the present embodiment, shown in Figure 2, support 21 comprises outer layer rack 211 close to each other and internal layer frame 212, and the edge of filter screen 22 is between outer layer rack 211 and internal layer frame 212.Namely the edge of filter screen 22 is clipped in the middle fixing by outer layer rack 211 and internal layer frame 212, makes filter screen 22 comparatively large with the contact area of outer layer rack 211, internal layer frame 212, contributes to increasing fastness.
In the present embodiment, support 21 is cylindrical shape, and outer layer rack 211 and internal layer frame 212 are two nested cylindrical shapes.
In the present embodiment, in order to increase the area of filter screen 22, reduce the possibility that screen pack 2 blocks, filter screen 22 is for having the tubular of bottom surface; Make filter screen 22 have bottom surface and side, filter area increases.The sectional area of the tubular of filter screen 22 reduces gradually near direction, bottom surface, and namely the diameter of tubular reduces gradually near direction, bottom surface; Make, between distance pipe arrangement 1 inwall of bottom surface, there is certain distance like this, when making cooling fluid flow through filter screen 2, part cooling fluid is by the bottom surface of filter screen 22, and part cooling fluid flows through gap between bottom surface and pipe arrangement 1 inwall, passes through through the side of filter screen 22 tubular.
The above, it is only preferred embodiment of the present utility model, be not restriction the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But everyly do not depart from technical solutions of the utility model content, any simple modification, equivalent variations and the remodeling done above embodiment according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
