Title: Dennis W. Weigand: Innovator in Refrigeration Technology

Introduction

Dennis W. Weigand is a notable inventor based in Theresa, Wisconsin, with a focus on refrigeration systems. He holds 2 patents that showcase his innovative contributions to the field. His work emphasizes efficiency and practicality in refrigeration technology.

Latest Patents

Weigand's latest patents include a refrigeration system and components thereof, which features a container with at least two different temperature cooling zones separated by a divider. This divider includes a wall and a partition that is spaced apart, with a heat transfer plate attached to a sheet containing a heat transfer substance. The refrigeration system is designed to be cooled by a variable capacity compressor system that operates in both refrigeration and hot-gas defrost modes. The system can be defrosted by circulating gas through it, and a controller is used to selectably operate the compressor system.

Another significant patent is the ice chest and cold plate apparatus, which is an improved design for use in beverage dispensers. This apparatus consists of an ice storage container with an open top, a bottom, and four sidewalls. A cold plate heat exchanger is affixed to the outer surface of the bottom of the ice storage container using a thermally conductive adhesive. The cold plate features multiple cooling circuits made of tubular coils that extend in a serpentine path and are die-cast in aluminum to form an aluminum block. This improved design is simpler, less expensive, and easier to manufacture compared to previous ice chests with cold plates.
