Abstract
A side plate for a heat exchanger, a heat exchanger and a method for making a heat exchanger are provided. The side plate, which may be incorporated into the heat exchanger, includes a first body piece having a first edge and a second body piece having a second edge. The first and second edges are separated by an opening except for point connections. After the heat exchanger is assembled the point connections may be sheared to permit the side plate to expand and contract as a result of positive and negative stresses.
Claims8
A side plate for use in a heat exchanger, the heat exchanger including a core extending along a longitudinal axis between a pair of spaced, generally parallel headers, the side plate comprising:
- a first body piece including a first edge;
- and
- a second body piece including a second edge, each of the first and second body pieces including a base and a leg extending generally normal from the base to produce a generally channel shape;
- the first and second edges defining at least one opening separating the first and second body pieces except for four or fewer point connections between the first and second edges,
- each of the point connections defined by intersecting portions of the first and second edges such that, when each of the four or fewer point connections break, the at least one opening and the connections allow the first and second body pieces to remain in contact while sliding past one another in a direction substantially parallel to the longitudinal axis to accommodate thermal expansion and contraction of the side plate;
- and
- wherein at least one point connection is located between the bases of the first and second body pieces and at least one point connection is located between the legs of the first and second body pieces.
A side plate for use in a heat exchanger, the heat exchanger including a core extending along a longitudinal axis between a pair of spaced, generally parallel headers, the side plate comprising:
- a first body piece including a first edge;
- and
- a second body piece including a second edge, each of the first and second body pieces including a base and a leg extending generally normal from the base to produce a generally channel shape;
- the first and second edges defining at least one opening separating the first and second body pieces except for a plurality of point connections between the first and second edges,
- each of the point connections defined by intersecting portions of the first and second edges and the point connections being breakable such that, when the plurality of point connections break, the intersecting portions of the first and second edges remain in overlapping engagement in a common plane along breakpoints formed during thermal expansion or contraction of the heat exchanger;
- and
- wherein at least one point connection is located between the bases of the first and second body pieces and at least one point connection is located between the legs of the first and second body pieces.
