Abstract

Display cases may include deflectors and fans. The deflectors may alter air currents generated by fans to provide an air current to display portions of the display case. In some implementations, the altered air current may have a first portion with a velocity that is greater than a velocity of a second portion, where the first portion is closer to a display portion of the display case.

Claims

1. A display case comprising:

a flow straightener comprising;

a first end;

a second end; and

a reference position, wherein the reference position comprises a position comprising approximately 0.8 times the distance between the first end and the second end from the first end; and

a deflector comprising;

a first member comprising a first position proximate an end of the first member; and

a second member comprising a second position proximate an end of the second member;

wherein the first member and the second member are coupled proximate a third position;

wherein a distance from the third position of the deflector to the reference position of the flow straightener comprises a first distance, and wherein a distance from the first position of the deflector to the first end of the flow straightener comprises approximately 3.5 times the first distance;

a fan adapted to generate a gas current directed at a surface of the deflector;

a display portion; and

wherein the gas current is altered by the deflector, and wherein a velocity of a first portion of the gas current is greater than a velocity of a second portion of the gas current, and wherein the first portion of the gas current is closer to the display portion than the second portion.

2. The display case of claim 1 wherein the flow straightener and the deflector are coupled proximate the second position of the deflector and proximate the second end of the flow straightener.

3. The display case of claim 1 further comprising a display portion, wherein a predetermined temperature range is maintained in the display portion of the display case using at least a portion of the gas current.

4. The display case of claim 1 wherein a velocity of a third portion of the gas current is at least one of less than or approximately equal to a velocity of the second portion of the gas current, and wherein the third portion of the gas current is disposed between the first portion and the second portion of the gas current.

5. The display case of claim 1 wherein the first member comprises a first dimension approximately 1.9 inches to approximately 2 inches high, and wherein the second member comprises a second dimension approximately 2.5 to approximately 2.9 inches high.

6. The display case of claim 1 wherein the flow straightener comprises an aspect ratio of 8:
