Abstract
Official abstract text for this publication.
Provided is a vehicle heat exchanger including a plurality of tubes through which a fluid flows, a plurality of cooling fins interposed between adjacent tubes, and a graphene material attached to a surface of each tube and/or a surface of each cooling fin. The graphene material may include a first graphene layer and a second graphene layer stacked on the first graphene layer.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicle heat exchanger, comprising: a plurality of tubes through which a fluid flows; a plurality of cooling fins interposed between adjacent tubes; a graphene material attached to a surface of each tube and/or a surface of each cooling fin; and a laser irradiator irradiating the graphene material with a laser of an infrared region. 2. The vehicle heat exchanger according to claim 1 , wherein the graphene material includes a first graphene layer and a second graphene layer stacked on the first graphene layer. 3. The vehicle heat exchanger according to claim 2 , wherein the first graphene layer has a first honeycomb lattice and a first axis extending along the first honeycomb lattice, the second graphene layer has a second honeycomb lattice and a second axis extending along the second honeycomb lattice, and the first axis of the first graphene layer and the second axis of the second graphene layer intersect at a predetermined twist angle. 4. The vehicle heat exchanger according to claim 1 , wherein the laser irradiator is disposed in front of the tubes and the cooling fins or behind the tubes and the cooling fins. 5. A vehicle front structure, comprising: a front end body; a front compartment sealed by the front end body; a plurality of heat exchangers received in the front compartment, wherein each heat exchanger includes: a plurality of heat exchange elements; and a graphene material attached to each heat exchange element and a laser irradiator irradiating the graphene material of each heat exchanger with a laser of an infrared region. 6. The vehicle front structure according to claim 5 , wherein the graphene material includes a first graphene layer and a second graphene layer stacked on the first graphene layer. 7. The vehicle front structure according to claim 6 , wherein the first graphene layer has a first honeycomb lattice and a first axis extending along the first honeycomb lattice, the second graphene layer has a second honeycomb lattice and a second axis extending along the second honeycomb lattice, and the first axis of the first graphene layer and the second axis of the second graphene layer intersect at a predetermined twist angle.
