Description
- The present invention relates generally to a heater core connector and more particularly to a low profile heater core connector which facilitates installation in a plurality of positions.
- Heater core connectors are typically used to connect heat exchanger tanks to other components in a vehicle. Ideally, the connectors have low profiles to comply with packaging requirements and facilitate a fluid tight seal between the heat exchanger tank and the other components.
- Prior art heater core connectors are typically comprised of stamped pieces that are brazed together with the heat exchanger to form a fluid-tight connection therebetween. However, the brazing employed on multiple-piece connectors often leaves the connection susceptible to leaking, and limits the available options for connection to extension tubes. Typical stamped, single-piece connectors only allow for use of circular cross-section inlet or outlet configurations, which limit the fluid circuit and the efficiency of the heat exchanger device.
- To overcome this problem, heater core connectors have been formed from a single piece of material that is bent to form a desired angle, wherein the brazing step is eliminated. However, typical design guides recommend that a minimum centerline bend radius of a tube section is one and one half times a diameter of the section. Such a bend radius yields connectors having lengths that are undesirable due to packaging limitations which require the connector to have smaller profiles.
- It would be desirable to produce a heater core connector having a low profile, wherein a size, a weight, and a cost of production thereof are minimized and wherein the heater core connector can be installed in a plurality of positions.

- In another embodiment, a heater core connector comprises: a first section connected to an extension tube and having a first end and a spaced apart second end; and a second section having a first end and a spaced apart second end, wherein the first end of the second section receives the second end of the first section, and wherein a longitudinal axis of the first section is selectively positionable with respect to a longitudinal axis of the second section.
- In another embodiment, a heater core connector comprises: a first section connected to an extension tube and having a first end and a spaced apart second end; and a second section disposed on a heat exchanger tank and having a first end and a spaced apart second end, wherein the first end of the second section receives the second end of the first section, and wherein a longitudinal axis of the first section is selectively positionable with respect to a longitudinal axis of the heat exchanger tank.
- The above, as well as other objects and advantages of the invention, will become readily apparent to those skilled in the art from reading the following detailed description of a preferred embodiment of the invention when considered in the light of the accompanying drawings in which:

Theintermediate portion 126 of thefirst section 120 has aninner surface 140 having a transition indiameter 142 that is adapted to abut adistal end 143 of thefirst extension tube 134. Theinner surface 140 is adapted to engage an O-ring 144 that is optionally disposed in achannel 146 formed in theextension tube 134. While a single O-ring 144 is shown in the drawings, additional O-rings (not shown) may be disposed in thechannel 146 or in additional channels (not shown) as desired. Theintermediate portion 126 has anouter surface 148 including a radially outwardly extendingannular bend 150 formed adjacent to thesecond end 124. - In the embodiment illustrated, the
second section 121 of the inletheater core connector 112 is formed separately from and secured to aninlet cover portion 151 of theheat exchanger tank 116. It is understood that thesecond section 121 can be formed integrally with theinlet cover portion 151 as desired without departing from the scope and spirit of the invention. - The
second section 121 of the inletheater core connector 112 includes afirst end 152, a spaced apartsecond end 154, and anintermediate portion 156, and a longitudinal axis L12. Thefirst end 152 includes a substantially circular shapedaperture 158 formed therein adapted to receive thesecond end 124 of thefirst section 120 of the inletheater core connector 112. A radially inwardly extendingannular lip 160 formed on thefirst end 152 is adapted to abut thebend 150 formed on theintermediate portion 126 of thefirst section 120. Thesecond end 154 of thesecond section 121 is disposed on thefirst end 118 of theheater core 110. - To assemble the
heater core 110, thefirst end 122 of thefirst section 120 of the inletheater core connector 112 receives thefirst extension tube 134. Thedistal end 143 of thefirst extension tube 134 abuts the transition indiameter 142 of theintermediate portion 126 of thefirst section 120 of the inletheater core connector 112. The O-ring 144 disposed between thefirst extension tube 134 and theinner surface 140 of thefirst section 120 of the inletheater core connector 112 forms a substantially fluid tight seal therebetween. Theclamp 136 is secured to the first flaredportion 128 of thefirst section 120 of the inletheater core connector 112 and thefirst extension tube 134 to militate against relative axial movement therebetween. It is understood that other means of securing thefirst section 120 of the inletheater core connector 112 to thefirst extension tube 134 can be used as desired, such as by brazing, for example. - The
