Abstract
A side sheet of a radiator has a thermal expansion joint to allow thermal relief in the radiator as the radiator expands due to temperature variations during operation. The thermal expansion joint is formed by first brazing the side sheet to the radiator core and then cutting through the side sheet.
Claims6
A side sheet for attachment to a radiator core, the side sheet comprising:
- a pair of side flanges;
- a top member connected to and extending between the side flanges;
- and
- a thermal expansion joint comprising a slot in the top member and side flanges of the side sheet having an angular orientation relative to a perpendicular line between the side flanges of the side sheet, the side sheet having an inlet end and an outlet end, opposite the inlet end, and the thermal expansion joint located closer to the inlet end than the outlet end of the side sheet by a ratio of the distance between the inlet end of the side sheet and a first end of the thermal expansion joint to the distance between the inlet and outlet ends of the side sheet of about 5:38.
1 more element
A radiator comprising:
- a core having a first side and a second side;
- a pair of side sheets attached to the core, a first side sheet attached to the first side of the core and a second side sheet attached to the second side of the core,
- wherein the side sheets have an inlet end and an outlet end, at least one of the side sheets has a thermal expansion joint comprising a slot having an angular orientation relative to a perpendicular line between the side flanges of the side sheet and the thermal expansion joint is located closer to the inlet end of the at least one of the side sheet by a ratio of the distance between the inlet end of the side sheet and a first end of the thermal expansion joint to the distance between the inlet and outlet ends of the side sheet of about 5:38.
