Abstract
Abstract In a laminated heat exchanger wherein partitions are provided in a plate (32) on a primary side and a plate (33) on a secondary side to form channels therein, and a plurality of the plates (32) on the primary side and the plates (33) on the secondary side are laminated one upon another with respective seal plates (3) therebetween, each of the partitions (35) of the plates (33) on the secondary side are located at positions opposed to each of the channels (11) of the plates (32) on the primary side and each of the partitions (34) of the plates (32) of the primary side are located at positions opposed to each of the channels (17) of the plates (33) on the secondary side, thereby preventing the seal plates (3) from being deformed even if pressure of the coolant flowing through the channels becomes nonuniform. Furthermore, sides of the plates (32) on the primary side, the plates (33) on the secondary side and the seal plates (3) are formed into shapes different from one another, thereby making it easy to identify falling-off of a plate.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
174 words
A layer-built heat exchanger comprising: a first-side plate having plural channels for coolant flow formed by dividers on a flat rectangular panel, a hole at one end of the channels, and a hole on a diagonal line to the first hole on a different side of the plate; a second-side plate having plural channels for coolant flow formed by dividers on a flat rectangular panel, a hole formed separately at one end of the channels continuously to the corresponding hole in the first-side plate, and a hole on a diagonal line to the first hole on a different side of the plate continuously to the corresponding hole in the first-side plate; and a seal plate between the first-side plate and the second-side plate, and characterized by the ends of the channels in the first-side plate and the second-side plate forming a rough V-shape centering on the hole in the respective plate such that the length of each channel increases with the increase in the distance of the channel from the center of the hole.
Claim 2
Dependent Claim
166 words
A layer-built heat exchanger comprising: a first-side plate having plural channels for coolant flow formed by dividers on a flat rectangular panel, a hole at one end of the channels, and a hole on a diagonal line to the first hole on a different side of the plate; a second-side plate having plural channels for coolant flow formed by dividers on a flat rectangular panel, a hole formed separately at one end of the channels continuously to the corresponding hole in the first-side plate, and a hole on a diagonal line to the first hole on a different side of the plate continuously to the corresponding hole in the first-side plate; and a seal plate between the first-side plate and the second-side plate, and characterized by the dividers of the channels in the second-side plate being positioned opposite the channels in the first-side plate, and the dividers of the first-side plate being positioned opposite the channels in the second-side plate, with the seal plate in between.
Claim 3
Dependent Claim
148 words
A layer-built heat exchanger comprising: a first-side plate having plural channels for coolant flow formed by dividers on a flat rectangular panel, a hole at one end of the channels, and a hole on a diagonal line to the first hole on a different side of the plate; a second-side plate having plural channels for coolant flow formed by dividers on a flat rectangular panel, a hole formed separately at one end of the channels continuously to the corresponding hole in the first-side plate, and a hole on a diagonal line to the first hole on a different side of the plate continuously to the corresponding hole in the first-side plate; and a seal plate between the first-side plate and the second-side plate, and characterized by the first-side plate, the second-side plate, and the seal plate each having a different and identifying shape at the outside edge thereof.
Claim 4
Dependent Claim
45 words
A layer-built heat exchanger according to Claim 2 wherein each of said first-side plates and the second-side plates is formed with convex members on different sides, and wherein each of said seal plates is formed with concave portions into which said convex members are inserted.
Claim 5
Dependent Claim
54 words
A layer-built heat exchanger according to Claim 2 wherein each of the first-side plates has rounded corners and wherein each of the second-side plates has beveled corners, and wherein each of the seal plates has corners formed in a shape different from that of the corners of the first-side plate and the second-side plate.
Claim 6
Dependent Claim
169 words
A layer-built heat exchanger comprising: a first-side plate having plural channels for coolant flow formed by dividers on a flat rectangular panel, a hole at one end of the channels, and a hole on a diagonal line to the first hole on a different side of the plate; a second-side plate having plural channels for coolant flow formed by dividers on a flat rectangular panel, a hole formed separately at one end of the channels continuously to the corresponding hole in the first-side plate; and a hole on a diagonal line to the first hole on a different side of the plate continuously to the corresponding hole in the first-side plate; a seal plate between the first-side plate and the second-side plate; an end plate provided on both ends; and inlet/outlet pipes for the first and second coolants provided on one of the end plates continuous to said holes such that the diameter of the holes in the first-side plate is smaller than the diameter of the inlet/outlet pipes.
Claim 7
Dependent Claim
187 words
A layer-built heat exchanger comprising: a first-side plate having plural channels for coolant flow formed by dividers on a flat rectangular panel, a hole at one end of the channels, and a hole on a diagonal line to the first hole on a different side of the plate; a second-side plate having plural channels for coolant flow formed by dividers on a flat rectangular panel, a hole formed separately at one end of the channels continuously to the corresponding hole in the first-side plate, and a hole on a diagonal line to the first hole on a different side of the plate continuously to the corresponding hole in the first-side plate; a seal plate between the first-side plate and the second-side plate; an end plate provided on both ends; and inlet/outlet pipes for the first and second coolants provided on one of the end plates continuous to said holes such that the inlet/outlet pipes are inserted to the end plate on the other side and a long hole is provided in the inlet/outlet pipes through the length of the first-side plate, second-side plate, and seal plate layers.
