Description
TITLE OF THE INVENTION:
method of cooling air circulated by a fan and a cooling fan NAME ( S ) OF INVENTOR ( S ) Kelly Duchesne FIELD OF THE INVENTION
The present invention relates to a method of cooling air circulated by a fan and a cooling fan BACKGROUND OF THE INVENTION
During the summer months, there are days of extremely high temperature when it is desirable to cool the air within residential and commercial buildings. In order to do so fans or air conditioners are used. Fans assist by circulating the air to create a breeze. The relief provided by the breeze is limited, as the air being circulated remains warm. Air conditioners have fans which circulate air through refrigerating units. The output of the air conditioning units is thermostatically controlled and can, therefore, be adjusted to whatever cooling temperature is desirable. Unfortunately, not everyone can afford an air conditioner.
SUMMARY OF THE INVENTION
What is required is a method of cooling air circulated by a fan.
According to one aspect of the present invention there is provided a method of cooling air circulated by a fan. A first step involves providing a fan having blades and a drive motor which rotates the blades. A protective cage encapsulates the blades, thereby preventing persons or objects from accidentally contacting the blades when they are rotating. A second step involves securing to the protective cage at least one package of frozen matter. Air circulated by the blades of the fan is cooled as said air passes by the at least one package of frozen matter.
4dith the method, as described above, the package of frozen matter can be taken from the freezer and mounted onto the protective cage. The air circulated by the fan will be cooled by the frozen matter. There are currently commercially available packages of frozen gel. These packages of frozen gel are used in food coolers and picnic baskets to keep food cool.
The packages of frozen gel can be refrozen and reused.
Although beneficial results may be obtained through the use of the method, as described above, this application requires that there be air circulation. Care must be taken to ensure that the size of the package of frozen matter does not block the air flow from the fan. Even more beneficial results may, therefore, be obtained when the at least one package has at least one air flow passage extending therethrough. This ensures there is never a blockage of air flow from the fan and brings the circulating air into more intimate contact with the frozen matter.
Although beneficial results may be obtained through the use of the method, as described above, after experimenting with different shapes it had been determined that it is preferred that the at least one package is annular with a central air flow passage. This "donut" shape appears to be both effective and relatively easy to manufacture. Fans and, consequently, the protective cages of fans come in a number of sizes and shapes. A number of small donuts can fit onto a protective cage regardless of its size and shape.
Although beneficial results may be obtained through the use of the method, as described above, of the various forms of frozen matter that can be used, gel appears to be most serviceable as evidenced by its use in food cooler and picnic basket applications.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
A cooling fan combination, generally identified by reference numeral 10, will now be described with reference to FIGURES 1 through 5.
Referring to FIGURE 1, a cooling fan 10 comprises in combination a fan 12 having blades 14, a drive motor, enclosed within a housing 16, a protective cage 18 encapsulating the blades 14, and several annular packages 20. Drive motor, enclosed within housing 16, rotates the blades 14 at a rate selected from among the settings available and controlled at control panel 21. Protective cage 18 encapsulates blades 14, thereby preventing persons or objects from accidentally contacting blades 14 when they are rotating. Annular packages 20 have a central air flow passage 22 and an outer perimeter 24. Referring to FIGURE 4, Annular packages 20 can be detachably secured to protective cage 18 by various means, in the illustrated embodiment a hook 26 is illustrated.
Referring to FIGURES 2 through 5, annular packages 20 and the means by which they may be attached to fan 12 will now be further described. Annular packages 20 have an outer skin 28 and an inner compartment 29 within which is contained a frozen gel 30. Outer skin 28 is manufactured from a material that is unaffected by repeated freeze-thaw cycles such as a polymer plastic. Frozen gel 30 is manufactured from a material or combination of materials which can be repeatedly frozen and thawed without deterioration, such as a frozen gel of the type utilized in packages of said frozen gel used to keep cool the contents of beverage containers, food packages and picnic hampers.
Referring to FIGURES 2 and 3, outer perimeter 24 of annular package 20 is preferably round, however said outer perimeter 24 can be of any geometric or decorative design without adversely affecting the performance of said annular package 20. Central air passage 22 of annular package 20 is preferably round, however said central air passage 22 can be of any geometric or decorative design without adversely affecting the performance of said annular package 20.
Referring to FIGURES 4 and 5, annular package 20 has a cross section shape that is substantially ~~D" shaped. A rear face 32 of annular package 20 is substantially planar thereby allowing said annular package 20 to lie in a substantially coplanar position on protective cage 18. A front face 34 of 5 annular package 20 is curved to allow air to pass over substantially all of said front face 34 and thereby be cooled in a most effective manner.
Referring to FIGURE 4, hook 26 is secured to rear face 32 close to outer periphery 24. Optionally annular package 20 may be detachably secured to protective cage 18 and more rigidly positioned thereon by use of a plurality of hooks 26 attached to rear face 32 of said annular package 20.
The dimensions of annular package 20 can be varied over a range of values. An effectiveness in cooling air passing by annular packages 20, and a length of time for which said annular packages 20 are effective for cooling said air, both depend upon the flow rate of said air and the heat capacity of said annular packages 20, which is in turn dependent upon the mass of frozen gel 30 in said annular packages 20. It has been found that, for satisfactory effectiveness in cooling air and length of time of said effectiveness, a first diameter of outer periphery 24 can be varied from a maximum value equal to a second diameter of protective cage 18 to a value approximately one fifth of said second diameter of protective cage 18. It has been found by experimentation that securing three or four of annular packages 20 of first diameter, shown as a first line 40 in FIGURE 2, approximately one third of second diameter of protective cage 18 to said protective cage 18 is more effective in cooling air than is securing a single annular package 20 of first diameter approximately equal to second diameter of protective cage 18. When three or four such annular packages 20 are to be secured to a fan of which protective cage 18 is approximately 300 millimetres (approximately 12 inches) the dimensions of each of said annular packages 20 are preferably as will now be described. The diameter 40 of outer periphery 24 is approximately 100 millimetres. A width of the "D" cross section of annular package 20, shown as a first double arrow 42 in FIGURE 2, is approximately 38 millimetres. A diameter of central air flow passage 22, shown as a second double arrow 44 in FIGURE 2, is approximately 25 millimetres. A depth of the "D" cross section of annular package 20, shown as a second line 46 in FIGURE 4, is approximately 32 millimetres. It has been found by experimentation that a thickness of approximately 2 millimetres for outer skin 28 can be used for a durable and effective product of the above dimensions. The depth of hook 26, shown as a third line 48 in FIGURE 4, is approximately 8 millimetres.
The use of cooling fan combination 10 will now be described with reference to FIGURES 1 through 5 having regard to the preferred method. A fan 12 is provided, as described above. One or a plurality of annular packages 20 of frozen gel 30 are secured to protective cage 18 by one or a plurality of hooks 26. As air is circulated by blades 14 of fan 12, the air is cooled as said air passes through the central air flow passage 22 and by the outer perimeter 24 of each annular package 20 of frozen gel 30.
As air passing through central air flow passage 22 and by outer periphery 24 of annular package 20 is cooled the heat which is given up by said air is transferred to frozen gel 30.
When frozen gel 30 is melted and warmed, annular package 20 is spent and is no longer effective for cooling air. Spent annular package 20 must be re-frozen or replaced with a replacement frozen annular package 20 to permit continued use of cooling fan 10 for cooling air. Annular package 20 is detached from protective cage 18 and placed in a freezer to be re-frozen. The re-frozen or replacement frozen annular package 20 is detachably secured to protective cage 18 to continue the use of cooling fan 10 for cooling air.
It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiment without departing from the spirit and scope of the invention as hereinafter defined in the Claims.
Referring to FIGURES 2 through 5, annular packages 20 and the means by which they may be attached to fan 12 will now be further described. Annular packages 20 have an outer skin 28 and an inner compartment 29 within which is contained a frozen gel 30. Outer skin 28 is manufactured from a material that is unaffected by repeated freeze-thaw cycles such as a polymer plastic. Frozen gel 30 is manufactured from a material or combination of materials which can be repeatedly frozen and thawed without deterioration, such as a frozen gel of the type utilized in packages of said frozen gel used to keep cool the contents of beverage containers, food packages and picnic hampers.
Referring to FIGURES 2 and 3, outer perimeter 24 of annular package 20 is preferably round, however said outer perimeter 24 can be of any geometric or decorative design without adversely affecting the performance of said annular package 20. Central air passage 22 of annular package 20 is preferably round, however said central air passage 22 can be of any geometric or decorative design without adversely affecting the performance of said annular package 20.
Referring to FIGURES 4 and 5, annular package 20 has a cross section shape that is substantially ~~D" shaped. A rear face 32 of annular package 20 is substantially planar thereby allowing said annular package 20 to lie in a substantially coplanar position on protective cage 18. A front face 34 of 5 annular package 20 is curved to allow air to pass over substantially all of said front face 34 and thereby be cooled in a most effective manner.
Referring to FIGURE 4, hook 26 is secured to rear face 32 close to outer periphery 24. Optionally annular package 20 may be detachably secured to protective cage 18 and more rigidly positioned thereon by use of a plurality of hooks 26 attached to rear face 32 of said annular package 20.
The dimensions of annular package 20 can be varied over a range of values. An effectiveness in cooling air passing by annular packages 20, and a length of time for which said annular packages 20 are effective for cooling said air, both depend upon the flow rate of said air and the heat capacity of said annular packages 20, which is in turn dependent upon the mass of frozen gel 30 in said annular packages 20. It has been found that, for satisfactory effectiveness in cooling air and length of time of said effectiveness, a first diameter of outer periphery 24 can be varied from a maximum value equal to a second diameter of protective cage 18 to a value approximately one fifth of said second diameter of protective cage 18. It has been found by experimentation that securing three or four of annular packages 20 of first diameter, shown as a first line 40 in FIGURE 2, approximately one third of second diameter of protective cage 18 to said protective cage 18 is more effective in cooling air than is securing a single annular package 20 of first diameter approximately equal to second diameter of protective cage 18. When three or four such annular packages 20 are to be secured to a fan of which protective cage 18 is approximately 300 millimetres (approximately 12 inches) the dimensions of each of said annular packages 20 are preferably as will now be described. The diameter 40 of outer periphery 24 is approximately 100 millimetres. A width of the "D" cross section of annular package 20, shown as a first double arrow 42 in FIGURE 2, is approximately 38 millimetres. A diameter of central air flow passage 22, shown as a second double arrow 44 in FIGURE 2, is approximately 25 millimetres. A depth of the "D" cross section of annular package 20, shown as a second line 46 in FIGURE 4, is approximately 32 millimetres. It has been found by experimentation that a thickness of approximately 2 millimetres for outer skin 28 can be used for a durable and effective product of the above dimensions. The depth of hook 26, shown as a third line 48 in FIGURE 4, is approximately 8 millimetres.
The use of cooling fan combination 10 will now be described with reference to FIGURES 1 through 5 having regard to the preferred method. A fan 12 is provided, as described above. One or a plurality of annular packages 20 of frozen gel 30 are secured to protective cage 18 by one or a plurality of hooks 26. As air is circulated by blades 14 of fan 12, the air is cooled as said air passes through the central air flow passage 22 and by the outer perimeter 24 of each annular package 20 of frozen gel 30.
As air passing through central air flow passage 22 and by outer periphery 24 of annular package 20 is cooled the heat which is given up by said air is transferred to frozen gel 30.
When frozen gel 30 is melted and warmed, annular package 20 is spent and is no longer effective for cooling air.
