Abstract

The present application provides an evaporator. The evaporator may include a housing, a coil assembly mounted within the housing, and a replaceable fan module positioned within the housing. The replaceable fan module may include a fan mounted therein.

First claim

The invention claimed is:

1. A cooler comprising:
an enclosure comprising a ceiling;
an evaporator positioned on the ceiling and comprising:
an evaporator housing, the evaporator housing comprising a top panel and a bottom drain pan, wherein the top panel comprises a plurality of top panel rails;
a coil assembly mounted within the evaporator housing;
a fan housing positioned within the evaporator housing, wherein the fan housing comprises a grill and a plurality of mounting rails;
a drain line extending to an exterior of the cooler;
wherein the fan housing comprises a replaceable fan; and
wherein the plurality of mounting rails of the fan housing mate with the plurality of top panel rails of the evaporator housing allowing the fan housing to slide in and out of the evaporator housing.

2. The cooler of claim 1 , wherein the fan housing comprises a fan assembly therein.

3. The cooler of claim 2 , wherein the fan assembly comprises the replaceable fan, a fan motor, and a fan mounting bracket.

4. The cooler of claim 1 , wherein the replaceable fan comprises a backward incline centrifugal fan.

5. The cooler of claim 1 , wherein the grill is attached to the fan housing using a plurality of clips.

6. The cooler of claim 1 , wherein the fan housing comprises a locking member positioned thereon.

7. The cooler of claim 6 , wherein the locking member is configured to mate with a receiving member positioned around the top panel of the evaporator housing thereby locking the fan housing in place.

8. The cooler of claim 1 , wherein the replaceable fan comprises a variable speed fan.

9. A cooled enclosure comprising:
an interior surface;
an evaporator positioned on the interior surface and comprising:
an evaporator housing, the evaporator housing comprising a top panel and a bottom drain pan, wherein the top panel comprises a plurality of top panel rails;
a coil assembly mounted within the evaporator housing;
a fan housing positioned within the evaporator housing, wherein the fan housing comprises a grill and a plurality of mounting rails;

wherein the plurality of mounting rails of the fan housing mate with the plurality of top panel rails of the evaporator housing allowing the fan housing to slide in and out of the evaporator housing; and
a replaceable fan positioned within a fan aperture of the fan housing, wherein the replaceable fan is configured to direct airflow out of the fan housing through the grill.

10. The cooled enclosure of claim 9 , comprising a drain line extending to an exterior of the cooled enclosure and operable to direct condensation to an exterior of the cooled enclosure.

11. The cooled enclosure of claim 9 , wherein the replaceable fan comprises a backward incline centrifugal fan.

12. The cooled enclosure of claim 9 , wherein the replaceable fan comprises a variable speed fan.

13. The cooled enclosure of claim 9 , wherein:
the fan housing comprises a fan assembly therein; and
the fan assembly comprises the replaceable fan, a fan motor, and a fan mounting bracket.

14. The cooled enclosure of claim 9 , wherein the grill is attached to the fan housing using a plurality of clips.

15. The cooled enclosure of claim 1 , wherein the fan housing comprises a locking member positioned thereon.

16. The cooled enclosure of claim 15 , wherein the locking member is configured to mate with a receiving member positioned around the top panel of the evaporator housing thereby locking the fan housing in place.

17. A freezer comprising:
an interior surface;
an evaporator positioned on the interior surface and comprising:
an evaporator housing, the evaporator housing comprising a top panel and a bottom drain pan, wherein the top panel comprises a plurality of top panel rails;
a coil assembly mounted within the evaporator housing;
a fan housing positioned within the evaporator housing, wherein the fan housing comprises a grill and a plurality of mounting rails;

wherein the plurality of mounting rails of the fan housing mate with the plurality of top panel rails of the evaporator housing allowing the fan housing to slide in and out of the evaporator housing; and
a replaceable fan positioned within a fan aperture of the fan housing, wherein the replaceable fan is configured to direct airflow out of the fan housing through the grill; and
wherein the fan housing is configured to accommodate a differently sized replaceable fan.

18. The freezer of claim 17 , wherein the replaceable fan comprises a backward incline centrifugal fan.

19. The freezer of claim 17 , wherein the replaceable fan comprises a variable speed fan.

20. The freezer of claim 17 , comprising a drain line extending to an exterior of the cooled enclosure and operable to direct condensation to an exterior of the cooled enclosure.
