Abstract
Description
- This application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/528,227, filed on Dec. 9, 2003, the entire contents of which are incorporated herein by reference.
- This invention relates to an evaporator device for an ice machine that has a small number of parts and an improved thermal transfer between a circulating refrigerant and an ice-forming surface. This invention also relates to a method for making the evaporator device.
- Evaporator devices generally include an array of ice cells arranged in a pattern and a refrigerant tube that is positioned adjacent the pattern to provide cooling during ice making and heating during defrost and harvest. For example, the pattern may be a plurality of parallel rows or a grid of horizontal rows and vertical columns.
- It is known to construct an ice cell array with thermally conductive metal, such as copper or aluminum. An example of a copper evaporator device is shown in U.S. Pat. No. 4,459,824. The evaporator device, when constructed of copper, is plated with a suitable metal, such as tin or nickel. The plating is required by National Sanitation Foundation codes, which prohibit the use of copper parts in contact with food products. The plating process results in waste products that need to be handled with environmentally acceptable procedures. In addition, plating degradation can occur at solder fillets used in the construction of the array of cells or their connection to other parts over which the water used in the ice making process may flow. This can result in a formation of copper oxides that could contaminate the ice.
- Examples of evaporator devices that use aluminum parts to construct the ice cell array are shown in U.S. Pat. Nos. 3,430,452, 5,129,237 and 5,193,357. For instance, U.S. Pat. No. 5,193,357 discloses a plurality of horizontal integral aluminum pieces arranged side by side to form a grid of ice cells. However, the back of each ice cell contains a gap that is filled entirely or partially with brazing material. Brazing material or soldering material can deteriorate over time, thereby resulting in unreliability. Moreover, the evaporator device construction is limited to one-sided ice cell arrays.
- U.S. Pat.
