Benefits of technology
The patent describes a heat exchanger system for refrigerators and freezers that includes a serpentine tubing system and a fan to circulate air. The system is designed to evenly distribute liquid heat exchange fluid throughout the heat exchanger. This results in improved heat transfer and more efficient refrigeration. The technical effects of this system include improved refrigeration efficiency, reduced energy consumption, and improved product quality.
Problems solved by technology
This presents a challenge to refrigerant system designers because to maintain satisfactory performance of the system, the system needs to be designed to flood the heat exchanger as much as possible with the restricted refrigerant charge level.
Stagnation of the refrigerant generally decreases the performance of the heat exchanger.
This decrease in performance may be compounded by a limited amount of refrigerant flowing through the heat exchange system.
However, decreasing the size of the heat exchanger also decreases the heat exchange ability of the system as the surface area available to heat or cool the refrigerant within the heat exchanger is reduced.

Embodiment Construction
[0016]Referring to FIG. 2, one embodiment of a heat exchange system 210 is shown installed within a side by side style refrigerator / freezer 200 (referred to herein as a “refrigerator” for exemplary purposes). It should be understood that while the aspects of the invention are described herein with respect to refrigerator 200, the aspects of the invention can be equally applied to any suitable refrigeration appliance.
[0017]The aspects of the disclosed embodiments provide a heat exchange system 210 capable of providing sufficient cooling for the refrigerator 200 where the amount of heat exchange fluid such as, for example, refrigerant, that can be used in the heat exchange system 210 is limited. In one embodiment, the heat exchange system 210 is configured so that the heat exchanger 220 is flooded with as much of the limited amount of heat exchange fluid, in liquid form, as possible. The heat exchanger 220 is configured such that the air flow over and / or through the heat exchanger 220...

A heat exchanger including a heat exchange fluid inlet, tubing coupled to the heat exchange fluid inlet, the tubing being configured to direct a flow of heat exchange fluid through the heat exchanger, the flow of fluid having a main fluid flow direction, and an air inlet configured to direct a flow of air in a generally collinear relationship with the main fluid flow direction.
Description
BACKGROUND OF THE INVENTION[0001]The present disclosure relates generally to heat exchangers. More specifically, the present disclosure relates to heat exchangers having a relatively low refrigerant charge.[0002]In a refrigerant-based heat exchange system, there are numerous reasons why the amount of refrigerant may need to be limited. These can include, for example, cost considerations, regulatory / environmental requirements and safety requirements. This presents a challenge to refrigerant system designers because to maintain satisfactory performance of the system, the system needs to be designed to flood the heat exchanger as much as possible with the restricted refrigerant charge level.[0003]In a typical refrigerant-based heat exchange system, the general refrigerant flow and air flow through the heat-exchanger (for example, an evaporator) are not collinear or in the same direction. For example, referring to FIG. 1, the refrigerant-based heat exchanger for, as an example, a refrig...
