This invention relates to cooling units designed primarily for coolingliquid and having a particular utility in cooling and drying liquid carbon dioxide preparatory to its admission for expansion to a carbon dioxide snow machine.
An object of the invention is to provide a cooling device which will be adapted to cool the fluid which passes through it to a very low temperature and to do this with the maximum of efficiency.
A further object is to provide a cooling device in which the cooled fluid may pass without danger of freezing in the cooler and thereby clogging the fluid conduits in the device.
A further object is to provide a device for cooling carbon dioxide which will remove water ice from the carbon dioxide.
A further object is to provide a device for drying a fluid by freezing out the water from the fluid.
Referring to the accompanying drawing which is made a part hereof and on -which 25 similar reference characters indicate similar parts,
The figure is a longitudinal sectional view of the cooler.
In the drawing numeral indicates the shell or casing of the cooler having end plates 11 and 12 secured therein so as to provide a fluid-tight fit Within the shelf. If desirable, the ends of the shell may be turned in as at 13 to assist in holding the end plates within the shell.
The casing is provided with inlet and outlet ports 14 and 15, respectively, for delivering the fluid which is to be cooled into and out of the container or shell. Means is provided for passing cooling iuid through the shell. This preferably consists of coils 16 and 17, one within the other and attached to headers 18 and 19. Inlet and outlet pipes 20 and 21 connect with the headers 19 and 18, respectively. The end plate 12 also is provided with an exhaust pipe 22 normally closed by a valve. In operation fluid to be cooled is admited to the port 14. Cooling uid under pressure is expanded into the 50 pipe 21 and passes through the header 18 into the coils 16 and 17 The expansion of this iuid from high to low pressure reduces its temperature to a very low degree. The cold fluid within the coils absorbs heat from the Huid to be cooled, which surrounds the coils. When used as a liquid cooling device in the manufacture of carbon dioxide snow, liquid carbon dioxide is reduced to a very low temperature within the shell 10. By having the tluid pass through a relatively large shell the danger of Water ice clogging the pipes is removed. As a coolant I preferably use carbon dioxide under pressure. This liuid under pressure is expanded into the inlet pipe 2l during which expansion its temperature is greatly reduced. The pipe 22 is provided for cleaning out the shell in case water ice does become frozen on the sides of the casing or on the cooling coils. This may be done by admitting hot gas to the shell.
While for most uses it may be preferable to pass the liuid to be cooled into a shell and l circulate a cooling medium through it, l do not limit myself to this method, as l may pass the fluid to be cooled through pipes or coils within the shell and admit cooling fluid to the shell surrounding the pipes or i coils. Furthermore, I do not llmit the invention yto the use of coils such as shown, or even to coils. Pipes, tubes or other conduits passing through the shell may besubstituted, or I may use any .fluid transmission means which will act to carry off the heat from the fluid to be cooled.
As stated in the objects of the invention, this device acts to dry a fluid as well as to cool it. By drying it in this sense I mean the removal of water therefrom. When liquid carbon dioxide is reduced toa low temperature any water contained in it is frozen on the coils 16 and 17. From time to time this may be thawed out and drained olf through the pipe 24.
It will be obvious to those skilled in the art that various changes may be made in my device without departing from the spirit of the invention, and I therefore do not limit myself to What is shown in the drawing and described in the specification but only as set forth in the appended claim.
Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:
A cooler comprising a casing forming a duid chamber, inlet and outlet ports to said chamber, a pair of headers in said chamber, said headers being connected b a plurality of nested coils, inlet and out et )ipes connected to said headers, said headers emg supported in said casing by said inlet and outlet pipes, and inlet and outlet connections to the interior of said chamber for passing warm Huid through the chamber for thawing out the chamber from time to time, substantially as set forth.
In witness whereof, I have hereunto set my hand at Waynesboro, Pennsylvania, this 16th day 0f Jan., A. D. 1929.
