Abstract

A heat exchanger for an automotive vehicle includes two headers, first tubes for carrying fluid between the headers, and second tubes for carrying engine coolant between the headers, staggered with respect to the first tubes, each tube inclined relative to an air stream entering the heat exchanger.

Claims

exact text as granted — not AI-modified
1 . A heat exchanger for an automotive vehicle comprising:
 two headers;   first tubes for carrying fluid between the headers;   second tubes for carrying fluid between the headers, staggered with respect to the first tubes, each tube including a depth dimension that is inclined at an angle relative to an air stream entering the heat exchanger.   
   
   
       2 . The heat exchanger of  claim 1  wherein each of the first and second tubes includes a length extending mutually parallel between the headers, and substantial parallel lateral surfaces that are inclined relative to the air stream entering the heat exchanger. 
   
   
       3 . The heat exchanger of  claim 1  wherein:
 the first tubes are arranged in a first row and the second tubes are arranged in a second row;   each of the first and second tubes has a length extending between the headers, and substantial parallel lateral surfaces, the lateral surfaces of the first and second tubes being inclined in a first direction relative to the air stream entering the heat exchanger.   
   
   
       4 . The heat exchanger of  claim 1  wherein:
 the first tubes are arranged in a first row and the second tubes are arranged in a second row;   each of the first and second tubes has a length extending between the headers, and substantial parallel lateral surfaces, the lateral surfaces of the first tubes inclined in a first direction relative to the air stream entering the heat exchanger, the lateral surfaces of the second tubes inclined in a second direction relative to the air stream entering the heat exchanger.   
   
   
       5 . The heat exchanger of  claim 1  wherein the angle may vary in a range up to about 20 degrees. 
   
   
       6 . The heat exchanger of  claim 1  wherein the tubes folded tubes that are welded or brazed along at least one longitudinal seam. 
   
   
       7 . A heat exchanger for an automotive vehicle comprising:
 two headers;   first tubes for carrying fluid between the headers, each first tube inclined at an angle relative to an air stream entering the heat exchanger; and   second tubes for carrying fluid between the headers, each second tube inclined at an angle relative to the air stream entering the heat exchanger and aligned with one of the first tubes.   
   
   
       8 . The heat exchanger of  claim 7  wherein each of the first and second tubes includes a length extending mutually parallel between the headers, and substantial parallel lateral surfaces that are inclined relative to the air stream entering the heat exchanger. 
   
   
       9 . The heat exchanger of  claim 7  wherein:
 the first tubes are arranged in a first row and the second tubes are arranged in a second row;   each of the first and second tubes has a length extending between the headers, and substantial parallel lateral surfaces inclined in a first direction relative to the air stream entering the heat exchanger.   
   
   
       10 . The heat exchanger of  claim 7  wherein:
 the first tubes are arranged in a first row and the second tubes are arranged in a second row;   each of the first and second tubes has a length extending between the headers, and substantial parallel lateral surfaces, the lateral surfaces of the first tubes inclined in a first direction relative to the air stream entering the heat exchanger, the lateral surfaces of the second tubes inclined in a second direction relative to the air stream entering the heat exchanger.   
   
   
       11 . The heat exchanger of  claim 7  wherein the angle may vary in a range up to about 20 degrees. 
   
   
       12 . The heat exchanger of  claim 7  wherein the tubes folded tubes that are welded or brazed along at least one longitudinal seam. 
   
   
       13 . A heat exchanger for an automotive vehicle comprising:
 two headers;   first tubes for carrying fluid between the headers;   second tubes for carrying fluid between the headers, staggered with respect to the first tubes, the first ands second tubes being substantially aligned with an air stream entering the heat exchanger.   
   
   
       14 . The heat exchanger of  claim 13  wherein:
 the first tubes are arranged in a first row and the second tubes are arranged in a second row;   each of the first and second tubes has a length extending between the headers, and substantial parallel lateral surfaces aligned with the air stream entering the heat exchanger.   
   
   
       15 . The heat exchanger of  claim 13  wherein the angle may vary in a range up to about 20 degrees. 
   
   
       16 . A heat exchanger for an automotive vehicle comprising:
 two headers;   first tubes for carrying fluid between the headers, each first tube inclined in a first direction at an angle relative to an air stream entering the heat exchanger; and   second tubes for carrying engine coolant between the headers, each second tube staggered with respect to the first tubes, and inclined in a second direction at an angle relative to the air stream entering the heat exchanger.   
   
   
       17 . The heat exchanger of  claim 16  wherein:
 the first tubes are arranged in a first row and the second tubes are arranged in a second row;   each of the first and second tubes includes a length extending between the headers, each of the first tubes includes substantial parallel lateral surfaces inclined in a first direction relative to said air stream, and each of the second tubes includes substantial parallel lateral surfaces inclined in a second direction relative to said air stream.   
   
   
       18 . A heat exchanger for an automotive vehicle comprising:
 two headers; and   tubes having a length extending between the headers for carrying engine coolant between the headers, and substantial parallel lateral surfaces that are inclined at an angle relative to an air stream entering the heat exchanger.   
   
   
       19 . The heat exchanger of  claim 18  wherein the angle may vary in a range up to about 20 degrees. 
   
   
       20 . The heat exchanger of  claim 18  wherein the tubes are folded tubes that are welded or brazed along at least one longitudinal seam.
