AI Technical Summary

Benefits of technology

The cooling tube system enhances temperature gradients by 5-25% and improves freeze time for food items by 5-20%, reducing energy usage and maintaining consistent temperatures within the refrigeration unit.

Problems solved by technology

Since those early days, means for cooling (and maintaining cooling) in refrigeration space have developed into complex apparatus, with sophisticated electronics, motors, compressors and similar equipment.
For example, one problem which occurs with respect to both residential and commercial refrigeration units relates to “hot spots.” Hot spots are commonly known in the refrigeration industry, and may be characterized as areas within a cooled refrigeration interior that experience relatively warmer temperatures than desired.

Abstract

A cooling tube system (100) is formed as part of a refrigerator shelf (102). The shelf(102) includes a frame (104) having a series of frame wires (106). Secured above and supported on the frame wires (106) are a set of cooling tubes (114). A fan (132) directs cool air generated from cooling air equipment (130) through vents (136) into the refrigerator interior (129). The air flows through rear hollow ends (140) of the cooling tubes (114). The cooling air (138) is directed toward the front (124) of the refrigerator (120).

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority of U.S. Provisional Patent Application Ser. No. 60 / 506,532 filed Sep. 26, 2003.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not applicable.REFERENCE TO A MICROFISHE APPENDIX[0003]Not applicable.BACKGROUND OF THE INVENTION[0004]1. Field of the Invention[0005]The invention relates to shelving which may be adapted for use with refrigerators and other articles employing refrigeration, and, more particularly, shelving having means for facilitating spatial cooling.[0006]2. Background Art[0007]Previous types of shelving have been developed for use as shelves for refrigerators and other types of refrigeration apparatus. For example, refrigerator shelving is often designed with means for permitting selected movement of the shelf within the refrigerator, in addition to providing adequate support for the shelf. Design features of refrigerator shelving may also relate to spillage, prevention of...
