Heat-receiving member and exhaust pipe heat-releasing system

Abstract

A heat-receiving member includes a base and a surface layer. The base has a surface and includes at least one of aluminum and an aluminum alloy. The surface layer is provided at the surface of the base. The surface layer is anodized.

1 . A heat-receiving member comprising:
 a base having a surface and comprising at least one of aluminum and an aluminum alloy; and   a surface layer provided at the surface of the base, the surface layer being anodized.   
     
     
         2 . The heat-receiving member according to  claim 1 ,
 wherein the heat-receiving member has a first region and a second region, the first region and the second region being to be located so that a distance between the first region and a high-temperature part of a heat source is larger than a distance between the second region and the high-temperature part, and   wherein the first region has emissivity higher than emissivity of the second region.   
     
     
         3 . The heat-receiving member according to  claim 2 ,
 wherein said surface layer is provided in the first region and has a micropore in which a metal is deposited.   
     
     
         4 . The heat-receiving member according to  claim 2 ,
 wherein said second region has an unanodized and exposed surface of the base.   
     
     
         5 . The heat-receiving member according to  claim 1 ,
 wherein the surface layer has a plurality of cracks.   
     
     
         6 . The heat-receiving member according to  claim 1 ,
 wherein the surface of the base comprises a first surface and a second surface located opposite to the first surface, the surface layer being provided at each of the first surface and the second surface.   
     
     
         7 . An exhaust pipe heat-releasing system comprising:
 an exhaust pipe comprising a metal; and   a heat-receiving member arranged to face a periphery of said exhaust pipe to receive heat energy released from the exhaust pipe, the heat-receiving member comprising:
 a base having a surface and comprising at least one of aluminum and an aluminum alloy; and 
 a surface layer provided at the surface of the base, the surface layer being anodized. 
   
     
     
         8 . The exhaust pipe heat-releasing system according to  claim 7 ,
 wherein the heat-receiving member has a first region and a second region, the first region and the second region being to be located so that a distance between the first region and a high-temperature part of the exhaust pipe is larger than a distance between the second region and the high-temperature part, and   wherein the first region has emissivity higher than emissivity of the second region.   
     
     
         9 . The exhaust pipe heat-releasing system according to  claim 8 ,
 wherein the surface layer is provided in said first region and has a micropore in which a metal is deposited.   
     
     
         10 . The heat-receiving member according to  claim 1 ,
 wherein the heat-receiving member is configured to receive heat energy released from a heat source.
