Application filed June 24,
This invention relates to What might be termed evaporators for mechanical refrigeration.
A primary object of the invention is to provide an apparatus of this character based on thermal contact of the refrigerant on all sides of the freezing compartment and having it circulate entirely around the ice making tray or container for holding the material to be frozen.
In the average standard coil now in use the refrigerant has thermal contact only with the bottom and the sides or a portion only of the freezing compartment and thus it will be seen that the desired low temperature is not produced except at the point where the coils contact the compartment. It is to overcome these objections that this invention is designed and the apparatus embodying it provides for the circulation of the refrigerant on top of the freezing tray compartment as well as on the bottom, both sides, and ends.
In carrying out these objects, the invention is susceptible of a wide range, of modification without departing from the spirit or sacrificing any of the advantages of the claimed invention; there being shown in the drawings for illustrative purposes a preferred and practical form, in which:
Figure 1 is a side elevation showing this invention applied;
Fig. 2 is an end elevation; and
Fig. 3 is a detail sectional view taken on the line 33 of Fig. 1;
Fig. 4C is a vertical section of a slightly different form of the invention; and
Fig. 5 is a similar view of still another form.
In the embodiment illustrated in Figs. 1 to 3 a boiler 1 is shown such as is ordinarily used in commercial coils of this character eX- tending from opposite sides of which are a plurality of tubes 2 which communicate with the interior of the boiler and with the freezing compartment or chamber 10. These tubes 2 are illustrated as spaced longitudinally from each other a suflicient distance to have arranged between them copper fins 3 such as are ordinarily used and the space between 50 the fins and tubes is sufficient to permit any 1930'. Serial No. 463,498.
drip water which may develop to flow freely without having any chance to congeal.
Any desired number of freezingcompart ments 10 may be used and they may be of any desired cross sectional contour. One is here shown closed throughout except at the front-end where it is provided with a hingedclosure 11 to provide for the insertion and removal of the tray or container 15 which is designed to hold the material to be frozen. This container or tray 15 is spaced from each of the compartment walls a suflicient distance to permit the free flowing of the refrigerant around said container on all sides so that its top, bottom, rear end and sides will be subjected to the thermal contact of the refrigerant. It is of course understood that the fins 3 operate to radiate the cold.
From the above it will be seen that the refrigerant flowing from the boiler 1 through tubes 2 enters the freezing compartment 10 at opposite sides and passes around the container 15 on all sides, over the top and under thebottom, completely surrounding it and the intense cold produced by this circulation of the refrigerant causes the water or other material in the tray to freeze quickly which of course is'very desirable in apparatus of this character.
The boiler 1 is shown equipped with a valved suction line 4 and a valved liquid line 5 such as are used in apparatus of this character.
The liquid level in the boiler 1 is shown by the dotted line a in Fig. 2.
In Fig. 4 a plurality of superposed freezing compartments 10a are shown each surrounded by a refrigerant containing space 26 or jacket supplied by tubes 2a leading from the boiler 1a and opening into space 2?) preferably at the top. These tubes 2a and spaces 26 ensure the free flowing of the refrigerant around the chambers 10a. In the form shown in Fig. 5 the construction is the same as in Fig. 4 except that two freezing compartments 106 only are shown and the refrigerant space 26 is supplied by means of a refrigerant inlet pipe 12 equipped with an expansion valve 13.
A suction line or outlet 14 leads from the refrigerant jacket 21). This form is used on dry systems instead of flooded systems in which latter the other forms are employed.
Without further description it is thought that the features and advantages of the invention will be readily apparent to those skilled in the art, and it will, of course, be understood that changes in the form, proportion and minor details of construction will be resorted to Without departing from the spirit of the invention or its scope as claimed.
I claim:
A refrigerating unit including a boiler with refrigerant containing tubes depending from opposite sides, a freezing compartment, the tubes being connected with opposite side walls of the freezing compartment and communicating with the interior, a container mounted in said compartment and spaced from the walls thereof between which and said Walls the refrigerant is adapted to flow to completely surround said container, and radiating fins connected with the side Walls of the container and extending upwardly between the spaced tubes.
