Definitions
- the present invention relates to a heat exchanger unit including a heat exchanger.
- Heat exchanger units are used in a variety of applications that require the transfer of heat from one space to another space.
- the heat exchanger unit includes a heat exchanger and a support assembly for supporting the heat exchanger. Heat transfers from ambient air surrounding the heat exchanger to fluid, i.e. refrigerant, in the heat exchanger.
- the heat exchanger includes a plurality of tubes. The fluid passes through the tubes and heat is transferred from the air surrounding the tubes to the fluid. Fins are generally disposed on the tubes to increase the surface area to the tubes to increase heat transfer from the air surrounding the tubes.
- such a heat exchanger unit is included in a non-mobile heat exchanger system such as a heat pump system.
- the heat pump system transfers heat from an exterior of a building to an interior of the building.
- the heat exchanger unit is disposed in the exterior of the building and heat is transferred from the heat exchanger unit to an interior unit disposed in the interior of the building.
- the heat is dispersed from the interior unit to air in the interior of the building to heat the interior of the building.
- the tubes of the heat exchanger may extend vertically such that the refrigerant flows vertically.
- the tubes of the heat exchanger extend horizontally such that the refrigerant flows horizontally.
- the heat exchanger configured with horizontal tubes is advantageous in the non-mobile heat exchanger unit due to packaging and size restraints.
- the tubes extend between a pair of manifolds.
- each tube has a circular-shaped cross-section.
- the brazed construction typically each tube has a hyper-ellipse-shaped cross-section, i.e. the cross-section is generally rectangular with rounded corners.
- the round tube and plate fin construction is conventionally used in the non-mobile heat exchanger unit. Because the refrigerant is colder than the ambient air flowing around the tubes, condensate forms on the tubes and fins. Because the tubes have the circular-shaped cross-section, the condensate drains from the tubes in response to gravitational force. However, the condensate drains from the tubes along the entire length of the tubes. A large pan is required to collect the drained condensate and to prevent the condensate from draining on water-sensitive components of the heat exchanger unit.
- the brazed construction has better heat transfer properties than the round tube and plate fin construction because brazing improves the thermal contact between the tubes and the fins and the hyper-ellipse-shaped cross-section of the tube creates less air flow resistance than do the round tubes.
- the tubes have the hyper-ellipse-shaped cross-section, condensate does not drain from the tubes in response to gravitational force.
- condensate that forms on a top surface of the hyper-ellipse-shaped cross-section does not drain from the tubes in response to gravitational force.
- the condensate accumulates on the tubes and is subject to freezing on the tubes and fins. Water further accumulates on the tubes and fins in the form of frost. As more condensate forms and freezes on the tubes and fins, the frozen condensate and the frost increases the air flow resistance of the tubes and fins, which leads to a decrease in air flow and heat transfer.
- a heat exchanger unit including a heat exchanger with tubes wherein condensate is drained from the tubes to prevent the accumulation of the condensate on the tubes.
- a heat exchanger unit whereby drained condensate is directed toward a common drainage point to manage the removal of the drained condensate.
- the present invention is a heat exchanger unit comprising a support assembly and a heat exchanger.
- the support assembly has at least one support surface extending in a first plane.
- the heat exchanger is coupled to the support surface and fixed relative to the first plane.
- the heat exchanger includes a first manifold and a second manifold extending in spaced relationship with one another and a plurality of tubes spaced from one another and extending between and engaging the first manifold and the second manifold.
- the tubes communicate fluid between the first manifold and the second manifold. At least a portion of each of the tubes extend angularly relative to the first plane for draining condensate along the tubes toward a common drainage point to remove the condensate from the tubes and focus the condensate to the common drainage point.
- the condensate is drained from the tubes, the condensate does not accumulate on the tubes and the fins.
- the prevention of the condensate from freezing maintains the free movement of air around the tubes of the heat exchanger and maintains the heat transfer capabilities of the heat exchanger.
- the drainage of the condensate toward the common drainage point provides for efficient management of condensate.
- the condensate is drained toward the common drainage point to prevent the splashing or dripping of condensate from the tubes to the support assembly along the length of the tubes.
- the condensate is focused toward the common drainage point and is easily removed from the heat exchanger unit from the common drainage point.
- the heat exchanger unit 20 may be a component of a non-mobile heat exchanger system, such as a heat pump system for a building.
- the heat exchanger unit 20 may be of the type disposed in an exterior of the building.
- heat is transferred from air of the exterior of the building to fluid, i.e. refrigerant, in the heat exchanger unit 20.
- the fluid may then be transferred to an interior unit disposed in an interior of the building where the heat is dispersed from the interior unit to air in the interior of the building to heat the interior of the building.

- the support assembly 22 includes a base 30, side panels 32 extending upwardly from the base 30, and a top panel 34.
- the base 30 presents the support surface 24 extending in the first plane 26.
- At least one of the side 32 and the top 34 panels defines a screen 36.
- one of the side and the top panels 32, 34 or any combination of the side panels 32 and/or the top panel 34 defines at least one screen 36.
- the base 30 of the support assembly 22 is configured to rest on a solid surface.
- the base 30 may be disposed on outdoor ground, on a cement slab, or on flooring. It should be appreciated that the base 30 may be disposed on any type of solid surface.
- the base 30 of the support assembly 22 is planar. It should be appreciated that the base 30 may include legs. In such a configuration, the legs present the support surface 24 extending in the first plane 26. It should also be appreciated that the base 30 may include a window mount to be mounted to a window sill of the building. In such a configuration, the heat exchanger unit may be cantilevered from the window mount.
- the base 30 may also include a ceiling mount to be mounted to a ceiling of the building or a wall mount to be mounted to a wall of the building.
- the support assembly 22 is arranged such that the first plane 26 is perpendicular to the direction of gravity.
- the heat exchanger 28 includes a first manifold 38 and a second manifold 40 extending in spaced relationship with one another.
- the heat exchanger 28 includes a plurality of tubes 42 spaced from one another and extending between and engaging the first manifold 38 and the second manifold 40 for communicating fluid between the first manifold 38 and the second manifold 40.
- each of the tubes 42 extends in parallel with one another.
- the panels 32, 34 defining the screen 36 allows the movement of air through the support assembly 22 to facilitate the transfer of heat between the tubes 42 of the heat exchanger 28 and the air moving around the tubes 42.
- fins 44 are disposed on the tubes 42 to increase the surface area of the tubes 42 to increase heat transfer from the air passing around the tubes 42.
- the fins 44 are preferably louvered to increase the surface area of the fins 44 and to increase heat transfer performance.
- the support assembly 22 encloses the heat exchanger 28.
- the heat exchanger unit 20 also includes heat exchanger equipment (not shown) as known to one skilled in the art.
- the support assembly 22 encloses heat exchanger equipment.
- the heat exchanger equipment includes a compressor and an expansion valve.
- the heat exchanger equipment also includes a fan 46 for blowing air over the tubes 42 of the heat exchanger 28.
- the fan 46 is shown as a fan blade.
- the fan blade is shown for illustrative purposes to show the location and the blowing direction of the fan 46 and it should be appreciated that the fan 46 may include any type of fan blade or blower.
- the fan 46 moves air through the support assembly 22.
- the support assembly 22 as shown in Figure 1 is a cuboid, i.e. a rectangular box; however it should be appreciated that the support assembly 22 may be any shape.
- the support assembly 22 may cylindrical.
- the side panels 32 are curved and the tubes 42, as shown in Figure 10, extend along arced paths between the first manifold 38 and the second manifold 40.
- each tube 42 has a hyper-ellipse-shaped cross-section, i.e. the cross-section is generally rectangular with rounded corners.
- each of the tubes 42 has a lower temperature than air surrounding the tubes 42 and fins 44, which may lead to the formation of condensate on the tubes 42 and fins 44.
- At least a portion of each of the tubes 42 extends angularly relative to the first plane 26 for draining condensate along the tubes 42 toward a common drainage point 62 to remove the condensate from the tubes 42 and focus the condensate to the common drainage point 62.
- each tube includes a continuously inclined surface for efficient drainage of condensate.
- the condensate is not subject to freezing on the tubes 42. In other words, in certain conditions the condensate would be subject to freezing on the tube and fins 44 if the condensate was not drained from the tubes 42. Frozen condensate on the tubes 42 would prevent the movement of air around the tubes 42 and the fins 44, which would lead to a decrease in heat transfer.
- the condensate is focused to the common drainage point 62, the condensate is easily managed and drained away from the heat exchanger unit 20. In other words, the condensate is drained toward the common drainage point 62 to prevent the splashing or dripping of condensate from the tubes 42 to the support assembly 22 along the length of the tubes 42.
- a tray (not shown) may be disposed below the common drainage point 62 to collect the condensate. Because the condensate is directed toward the common drainage point 62, the tray need not extend below the tubes 42 along the length of the tubes 42 but rather only below the common drainage point 62.
- the tubes 42 preferably include a first section 48 extending at a first angle A relative to the first plane 26.
- the first angle is greater than or equal to 5 degrees.
- the support assembly 22 is arranged such that the first plane 26 is perpendicular to the direction of gravity.
- the support surface 24 is disposed on a surface that is perpendicular to the direction of gravity.
- the first angle A preferably maximizes the drainage of condensate from the tubes 42 while minimizing unused space in the support assembly 22.
- the support assembly 22 is aesthetically pleasing when the side panels 32 of the support assembly 22 extend upwardly perpendicularly to the first plane 26.
- unused space being generally triangularly-shaped exists above the tubes 42 and below the tubes 42.
- Figure 11 illustrates an effect of varying magnitudes of the first angle A on the air flow resistance of the heat exchanger. For example, as shown in Figure 11, the first angle A having a magnitude of 90 degrees results in the lowest air flow resistance and the first angle A having a magnitude of 0 degrees results in the highest air flow resistance.
- the first angle A may be of any magnitude that maximizes the drainage of condensate from the tubes 42 while minimizing unused space in the support assembly 22.
- the heat exchanger 28 is coupled to the support assembly 22 in any manner known to one skilled in the art.
- the heat exchanger 28 may include a bracket engaging the support assembly 22.
- the bracket may extend from one of the manifolds 38, 40.
- the heat exchanger 28 may include a core reinforcement plate extending between the manifolds 38, 40 and the bracket may extend from the core reinforcement plate.
- the bracket may be sized and shaped to be snapped onto or press-fit onto the manifold or the core reinforcement plate. Alternatively, the bracket may be brazed to the manifold or the core reinforcement plate or may be extruded with the manifold.
- the support assembly 22 may include a plate extending vertically with the bracket extending from the manifold and engaging the plate such that at least a portion of each of the tubes 42 extends angularly relative to the first plane 26.
- the support assembly 22 may include a crossbar extending horizontally with the bracket extending from the core reinforcement plate and engaging the crossbar such that at least a portion of each of the tubes 42 extends angularly relative to the first plane 26.
- the heat exchanger 28 may include a spacer disposed between the base 30 of the support structure and one of the manifolds 38, 40 while the other of the manifolds 38, 40 is disposed on the base 30 of the support structure such that the tubes 42 extend angularly relative to the first plane 26.
- each of the tubes 42 may include sections with a bend between each section. It should be appreciated that the configurations described below are exemplary and the heat exchanger 28 of the present invention may include any number of sections and/or bends.
