1 Claim.
The present invention relates to dehydrators for the refrigerant in refrigerating systems. Dehydrators of this type consist of a cartridge or casing through which the refrigerant passes. The cartr'dge contains dehydrating material such as .ca gel. In devices of this kind it has been found that leaks sometimes develop due ap arently to a sand blast eiiect produced by the stream of refrigerant acting in conjunction th the silica gel particles resulting in a small opening in the wall of the cartridge.
Among "51S objects of the present invention is to elirinate the possibility of such action and the con. quent leakage.
ther objects will readily occur to those skilled in the art upon reference to the following description and the accompanying drawin s in which 1 is a central longitudinal section of a cartridg made accordance with the present invention.
Fig. .2 is a side elevation of the same.
Fig. 3 is an enlarged view of one of the details shown in Fig. 1.
Fig. l is a sectional view of a modified structure of a detail.
In the drawing the dehydrator is shown as consistin of a tubular casing it having its ends reduced and provided in each end with a partition member ii and HA each of which carries a screen element 52. In producing the dehydrator the casing is first internally ribbed as at $3 to provide location means for the elements ii and HA with their screens 12. After one of these latter elements is inserted, the adjacent end of the casing tube is reduced to fix it in place. The casing is then supplied with sufficient silica gel to fill to about the other rib l3 and the other element H or HA inserted. whereupon, the other end of the casing is reduced.
The refrigerant conduits l5 and it are then soldered, brazed or otherwise connected to the reduced ends as to produce a leak-proof joint, the inlet lines it being connected to that end carrying the element 1 I and the outlet line It to the other end.
In Fig. 3 there is shown enlarged the partition element H with its screen l2.
In this figure the element is shown to be a shallow cup having its walls turned back and extended beyond the cup bottom and spaced to provide a channel 56 receiving the edge of the previously formed cup-shaped screen i2. After the screen edge has been placed in the channel, the extreme edge EEA is spun or otherwise turned inwardly to hold the screen in place.
As will be noted in this figure, the bottom Wall of the cup will be provided with a central imperforate area or portion l8 surrounded by an area containing a plurality of openings ll and instead of punching out the metal, the openings are by slitting and raising the metal into louvers HA so that, at each opening, there is a which will. preclude the possi ility of the of refrigerant entering through conduit iifrom being directed against the screen 52 and through the latter against the silica gel.
As is ndicated in Fig. 1, it sometimes happens that the inner end of conduit Hi, instead of being arran ed axially, is slightly bent, as for example, at When this condition prevails, if the openings through element l! are not baflled, the iiqui stream may be directed through such an opening so that the jet strikes the screen E2 of being broken up by the central im- .te portion of the element.
The element i in may be similar to element M if desired, but need not be. In Fig. 1, element MA is shown as provided with punched holes 2! but is otherwise like element l l.
In Fig. l the partition element l l i is shown as being identical with element ll except that the openings iii are provided with louvres 5 HA upstanding from both surfaces of the cup bottom.
I claim:
In a dehydrator for refrigerating systems, in which a body of dehydrating material is enclosed in a tubular casing provided with an axially located inlet and an axially located outlet, and which perforated partition elem nts are fixed adjacent said inlet and outlet iorlocating and confining material, the partition elements consisting of cup members. opening toward the inlet and outlet, each having its edge turned back upon itself and a cup shaped screen fixed within the turned back edge and having its bottom area spaced from the bottom area of the cup member, the bottoms of said cup members having a central imperiorate area surrounded by an area provided with openings and having louvres over said openings.
