In description of the present utility model, unless otherwise clearly defined and limited, term " is connected " or " connection " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or integral; It can be mechanical connection; Can be directly be connected, also indirectly can be connected by intermediary, can be the connection of two element internals or the interaction relationship of two elements.For the ordinary skill in the art, concrete condition the concrete meaning of above-mentioned term in the utility model can be understood.
Below with reference to Fig. 1-Fig. 2, the capillary 1 according to the utility model embodiment is described.
According to the capillary 1 of the utility model embodiment, as shown in Figure 1, comprising: body 10, a part for the tube wall of body 10 is outwardly to limit positioning convex 12.
It should be noted that, capillary 1 is applied in refrigeration plant usually, and refrigerant flows through capillary 1 with step-down, heat radiation.For convenience of describing, below be all positioned on filter 2 with one end of capillary 1 by positioning convex 12, the other end of capillary 1 connection evaporimeter is that example is described.Certain those skilled in the art can be understood as, and capillary 1 can also be located by connecting on other equipment by positioning convex 12, will be not described in detail at this.
Wherein, as shown in Figure 2, filter 2 is provided with pilot hole 21, and a part for capillary 1 extend in pilot hole 21, and positioning convex 12 is only against on the end face S of pilot hole 21.In some instances, capillary 1 is fixed on filter 2 by welding manner after locating.
The degree of depth that capillary 1 is inserted into filter 2 is approximately equal to the distance of the one end being inserted into filter 2 to positioning convex 12 of capillary 1, and this distance is limited the distance of positions from L.Capillary 1 can carry out locating and machining projection 12 by the spacing distance L needed for reality when producing, and when when ensureing to produce in enormous quantities, capillary 1 assembles with filter 2, position location is consistent.
And positioning convex 12 be arranged so that the part that capillary 1 stretches in filter 2 is unlikely long, avoid capillary 1 and stretch into long and inserted through the filter screen 22 in filter 2 or miscellaneous part, it also avoid the blockage problem of capillary 1.This design does not affect the caliber of capillary 1 yet, and compared to being suppressed the capillary realizing location by Z-type frock, the material usage of capillary 1 is less, the flow of capillary 1 have also been obtained effective guarantee, the cold medium flux flowing into evaporimeter from capillary 1 is even, thus makes evaporator temperature relatively more even, and heat transfer effect improves greatly, and then effectively reduce energy consumption, improve refrigeration.
In addition, because positioning convex 12 can only be against on the end face S of pilot hole 21, capillary 1 and filter 2 are attached and puts in place, refrigerant not easily leaks, and refrigerant consumption is few.
In some instances, capillary 1 adds man-hour, and carried out beating pier to generate positioning convex 12 to each capillary 1 by machine needle, the positioning convex 12 namely on capillary 1 is shaping by machine pusher, certain positioning convex 12 is also shaping by other modes, does not do concrete restriction here.
Because capillary 1 to be determined the position of positioning convex 12 by spacing distance L, the production standard of capillary 1 is unified, be convenient to capillary 1 produce in enormous quantities, uniformity, the product quality of capillary 1 obtain effective guarantee, improve the production efficiency of capillary 1, improve the reliability of product, improve product attraction, and reduce the scrappage of capillary 1, thus improve the production efficiency of refrigeration plant, reduce the production cost of refrigeration plant.
According to the capillary 1 of the utility model embodiment, by arranging positioning convex 12 with location on the tube wall of capillary 1, reducing the material usage of capillary 1, improving homogeneity of product and the product quality of capillary 1, improve the production efficiency of capillary 1, reduce production cost.And the flow of capillary 1 is effectively ensured, improve the reliability of product, be convenient to reduce energy consumption and the coolant leakage amount of the refrigeration plant being provided with capillary 1.
In certain embodiments, positioning convex 12 is two and radial symmetric is arranged, and here, two positioning convex 12 can complete positioning action substantially.Because positioning convex 12 quantity is few, add man-hour capillary 1 little in the distortion of positioning convex 12 place, improve the structural strength of capillary 1.
Certainly, positioning convex 12 can more than two, and multiple positioning convex 12 is arranged around the axis at intervals of capillary 1.
In further embodiments, positioning convex 12 is formed as annular protrusion, and that is, positioning convex 12 is one and axis around capillary 1 is arranged.Thus, capillary 1 positioning precision is high, and the mold shape of processing capillary 1 being positioned to protruding 12 is comparatively simple, thus reduces the production cost of capillary 1 further.
Particularly, as shown in Figure 1, the periphery wall 121 of positioning convex 12 is formed as cambered surface.Thus, the periphery wall 121 of positioning convex 12 not easily occurs that stress is concentrated, thus avoids breaking of capillary 1, ensure product quality.
Advantageously, be arc transition between other parts of positioning convex 12 and tube wall.Thus, also not easily occur between other parts of positioning convex 12 and tube wall that stress is concentrated, and avoids breaking of capillary 1, thus ensures product quality further.
According to the capillary 1 of the utility model embodiment, by arranging positioning convex 12 with location, improve the homogeneity of product of capillary 1, improve the production efficiency of capillary 1, reduce production cost.And the caliber of capillary 1 is unaffected, uniform flow.
According to the filter assemblies 100 of the utility model embodiment, comprise the capillary 1 according to the utility model above-described embodiment and filter 2.
In the filter assemblies 100 of the utility model embodiment, as shown in Figure 2, filter 2 is provided with pilot hole 21, and the part of capillary 1 extend in pilot hole 21 and positioning convex 12 is only against on the end face S of pilot hole 21.
Thus, the positioning precision of capillary 1 is high, avoids capillary 1 and stretches into long and inserted through the filter screen 22 in filter 2 or miscellaneous part, it also avoid the blockage problem of capillary 1.And capillary 1 and filter 2 attach and put in place, refrigerant not easily leaks, and refrigerant consumption is few, improves the production efficiency of filter assemblies 100, reduces the production cost of filter assemblies 100.
