Protecting structure of heat exchanger for motor vehicle

Abstract

A protect structure, of a heat exchanger for a motor vehicle, includes a core part of the heat exchanger and a protect member. The core part has a plurality of tubes and fins that are alternately arranged with each other, and the protect member is provided at a front side of the core part. The protect member has a plurality of protecting portions extending in a longitudinal direction of the tubes to cover front sides of the tubes of the core part and avoid a collision between the core part and an attack object that is flown from an oblique front side of the motor vehicle toward the core part.

1 . A protect structure of a heat exchanger for a motor vehicle, the protect structure comprising:
 a core part of the heat exchanger including a plurality of tubes and fins that are alternately arranged with each other; and   a protect member that is provided at a front side of the core part, wherein   the protect member has a plurality of protecting portions extending in a longitudinal direction of the tubes to cover front sides of the tubes of the core part and avoid a collision between the core part and an attack object that is flown from an oblique front side of the motor vehicle toward the core part, and wherein   an inner fin is installed inside each of the tubes of the heat exchanger, being positioned by a plurality of embossed portions formed on the tubes, and the protect member is provided with a plurality of fixing portions which are engaged with the embossed portions so that the protect member is fixed to the heat exchanger.   
   
   
       2 . The protect structure of the heat exchanger for the motor vehicle according to  claim 1 , wherein
 the protecting portions are formed to have a cross section so that an opening length formed between adjacent rear edge portions of the adjacent protecting portions is set to be smaller than an opening length formed between adjacent front tip portions of the adjacent protecting portions.   
   
   
       3 . The protect structure of the heat exchanger for the motor vehicle according to  claim 2 , wherein
 the protecting portions are formed to have a cross section formed like a triangular shape which is converged toward a front side of the motor vehicle.   
   
   
       4 . The protect structure of the heat exchanger for the motor vehicle according to  claim 2 , wherein
 the protecting portions are formed to have a cross section formed like a semi-circular shape at a front side of the motor vehicle.   
   
   
       5 . (canceled) 
   
   
       6 . The protect structure of the heat exchanger for the motor vehicle according to  claim 1 , wherein
 the protecting portions are formed to have a cross section formed like a triangular shape which is converged toward a front side of the motor vehicle.   
   
   
       7 . The protect structure of the heat exchanger for the motor vehicle according to  claim 1 , wherein
 the protecting portions are formed to have a cross section formed like a semi-circular shape at a front side of the motor vehicle.
