Abstract
A merchandising cooler has a thermoelectric cooling module with a thermoelectric array. Direct current is supplied to the thermoelectric array, thereby producing a cold side and a hot side. The thermoelectric array is mounted in an insulated container so that either the cold side or the hot side is in thermal communication with the interior space of the container and the other side is in thermal communication with the ambient environment. Depending on the arrangement and current flow, the device can either cool or heat displayed merchandise.
Description
- This invention relates generally to coolers and more particularly to a novel and highly effective merchandising cooler that maximizes packout (i.e., the amount of merchandise that the cooler can store and cool) and minimizes footprint (i.e., the floor space the cooler requires).
- Conventional merchandising coolers utilize mechanical refrigeration to chill merchandise, such as food and beverages, which is best kept and sold at lower temperatures that the ambient temperature of the environment in which the items are sold. These conventional coolers operate according to the same general principles as a home refrigerator, and include a compressor, a pump, and a condenser coil. They are accordingly expensive, bulky, and inefficient. Further, these conventional refrigeration units tend to have a large footprint. Floor space in a retail environment can be scarce and costly; accordingly, these conventional arrangements fail to provide an adequate packout relative to their footprint. Mechanical refrigeration units can moreover be costly to maintain.
- Recently, thermoelectric technology has been utilized in a wide variety of applications. Thermoelectric arrays are solid-state heat pumps that utilize one or more physical effects such as the Peltier effect and Thompson effect. In operation, direct current flows through the thermoelectric cooler, causing heat to be transferred from one side of the array to the other, creating a cold side and a hot side. The cold side of the thermoelectric array can be placed in or adjacent to a selected area or device for cooling purposes.
- Thermoelectric cooling does away with the bulky coils and compressors used in conventional refrigeration. Thus, refrigeration can be supplied to places that do not accommodate conventional refrigeration systems. For example, thermoelectric cooling has been used successfully to cool integrated circuit (IC) components to improve their performance. More recently, thermoelectric cooling has been used to cool small, portable coolers. These conventional units include a 40-quart thermoelectric cooler sold under the trademark COLEMAN. While these units may provide a sufficient solution for use in a personal, home or travel environment, they are not equipped to provide the combination of large packout and small footprint that is desirable in a merchandising environment. Additionally, the thermoelectric coolers known in the art do not adequately display the refrigerated goods offered for sale and are not designed in a way that enables efficient maintenance.
- Therefore, a need exists for a small-footprint cooler that can hold a large quantity of merchandise, display it attractively to potential consumers, and chill it efficiently. Further, a need exists for a cooler with a cooling module that facilitates the efficient manufacture, maintenance, repair or replacement of the cooling module.
- According to an exemplary embodiment of the present invention, a merchandising cooler is provided that includes a thermoelectric cooling module having a supplemental radiator on the hot side and an insulated container having one or more transparent side or top portions that facilitate viewing of the contents of the insulated container.
- Another exemplary embodiment of the merchandising cooler of the present invention includes a thermoelectric cooling module mounted in the top of the cooler and having a supplemented radiator on the hot side and an insulated container having a transparent top portion.
- In further embodiments of the present invention, the thermoelectric module is mounted in various different locations in the top of the cooler, with one or more transparent panels in various sides or top portions of the cooler, and further, with opening mechanisms which are hinged, slidable, or can otherwise be opened to allow access to the contents of the merchandising cooler. In one embodiment, the merchandising cooler is configured to be mountable on a countertop.
- The system and method of the invention provide a number of benefits. Thermoelectric cooling is less expensive and less bulky than conventional refrigerator coolers used in the sale of goods. By virtue of the less bulky design, the merchandising cooler of the present invention can maximize packout for a given footprint. Additionally, the modular design of the thermoelectric cooling module of the present invention facilitates efficient manufacture and maintenance.
- For a more complete understanding of the present invention, the needs satisfied thereby, and the objects, features, and advantages thereof, reference now is made to the following descriptions taken in connection with the accompanying drawings.

Asupplemental radiator 52 of thethermoelectric cooling module 12 is coupled to the warm-side heat radiator 53 and provides increased efficiency in evacuating thermal energy from the insulated container 50. Thesupplemental radiator 52 may comprise an array of fins in contact withradiator 53 or a coil through which a liquid is circulated. A fan 51 may be employed to circulate air over the fins or coil. Thefan 56 is used to circulate air inside theinsulated container 14 to facilitate the transfer of heat to the heat sink 55, which is chilled by thethermoelectric array 54. Thermal energy is dissipated in the atmosphere from thesupplemental radiator 52 by the fan 51, which may be coupled to a vent in the top of thethermoelectric cooling module 12. This arrangement may be easily configured to chill the contents of an insulated container of the present invention to temperatures below 50 degrees Fahrenheit. In another embodiment of the invention, the hot and cold sides can be interchanged to warm the displayed merchandise. - The
thermoelectric cooling module 12 is a self-contained and may include the elements 51-56 ofFIG. 5 in addition to other elements. Thethermoelectric cooling module 12 in any event must contain a thermoelectric array and two heat exchangers (a heat sink on the cold side and a heat radiator on the hot side).

In either case, the fit is snug, and insulation is provided around the module and a lid for accessing the module, the interior of the container, or both. Themodule 12 can be on any side of thecontainer 14, including the bottom, but is preferably in the top or a side wall. The self-containment of all components of thethermoelectric cooling module 12 also facilitates inexpensive and simple manufacture of theentire merchandising cooler 10. Thethermoelectric cooling module 12 may be fastened to theinsulated container 14 in a number of different ways. In various embodiments, thethermoelectric cooling module 12 is coupled to theinsulated container 14 with the use of suitable means facilitating the removal of thethermoelectric cooling module 12, as explained above.
