Heat exchanger

Abstract

A heat exchanger includes a heat transmitting structure for heat exchange and a guide member. The heat exchanger is configured to exchange heat between external fluid flowing outside the heat transmitting structure and the heat transmitting structure. The heat transmitting structure includes a plurality of heat transmitting members for heat exchange. The heat transmitting members are arranged side by side in such a manner as to have intervals between the adjacent heat transmitting members. The guide member is arranged in the intervals between the heat transmitting members so as to change a direction of the external fluid flowing outside the heat transmitting structure.

1 . A heat exchanger comprising a heat transmitting structure for heat exchange and a guide member, the heat exchanger being configured to exchange heat between external fluid flowing outside the heat transmitting structure and the heat transmitting structure,
 the heat transmitting structure including a plurality of heat transmitting members for heat exchange, the heat transmitting members being arranged side by side in such a manner as to have intervals between the adjacent heat transmitting members,   the guide member being arranged in the intervals between the adjacent heat transmitting members so as to change a direction of the external fluid flowing outside the heat transmitting structure.   
     
     
         2 . The heat exchanger according to  claim 1 , wherein
 the heat transmitting members include pipes inside which internal fluid for heat exchange can flow, and   heat is exchanged between the external fluid flowing outside the heat transmitting member and the internal fluid flowing inside the heat transmitting member.   
     
     
         3 . The heat exchanger according to  claim 2 , wherein
 the heat transmitting members are arranged to extend in a direction crossing the flowing direction of the external fluid, and arranged side by side in a direction crossing a plane defined by a longitudinal direction of the heat transmitting members and the flowing direction.   
     
     
         4 . The heat exchanger according to  claim 3 , wherein
 at least two of the heat transmitting members are arranged to be in parallel to each other.   
     
     
         5 . The heat exchanger according to  claim 4 , further comprising a housing space for housing the heat transmitting structure, and the external fluid flows through the housing space. 
     
     
         6 . The heat exchanger according to  claim 1 , wherein
 the heat transmitting members extend in a spiral manner, and include crossing members that are arranged to extend in the direction crossing the flowing direction of the external fluid and connecting members that connect upstream members which are the crossing members located upstream in the flowing direction and downstream members which are the crossing members located downstream in the flowing direction.   
     
     
         7 . The heat exchanger according to  claim 6 , wherein
 the guide member is arranged in one or both of between adjacent first connecting members which are the connecting members located on one end sides of the crossing members and between adjacent second connecting members which are the connecting members located on the other end sides of the crossing members.   
     
     
         8 . The heat exchanger according to  claim 7 , wherein
 the heat transmitting members are arranged side by side in such a manner as to have regular intervals between the adjacent heat transmitting members.   
     
     
         9 . The heat exchanger according to  claim 1 ,
 the guide member includes a plate-like portion interposed between the heat transmitting members, and a protruding portion protruding from a plane of the plate-like portion.   
     
     
         10 . The heat exchanger according to  claim 9 , wherein
 the protruding portion of the guide member protrudes obliquely toward the heat transmitting members forming an interval including the plate-like portion.
