Disclosed are a heat conductive surface structure for a combustion chamber and an engine cylinder block. The heat conductive surface structure for a combustion chamber comprises a substrate having a heat-receiving surface, multiple horizontal reflection grooves arranged horizontally on the heat-receiving surface, and multiple slanted reflection grooves arranged slantedly on the heat-receiving surface; between two neighboring horizontal reflection grooves is a horizontal load surface, between two neighboring slanted reflection grooves is a slanted load surface, and arranged at the intersection of a horizontal load surface and a slanted load surface is an independent concave curved reflection surface; the horizontal reflection grooves and the slanted reflection grooves form angles of a certain degrees; the horizontal reflection grooves and the slanted reflection grooves all have curved reflection surfaces; the longitudinal direction of the horizontal reflection grooves is perpendicular to the movement direction of high-speed, high-temperature air flow. The heat-conductive surface is formed by functional material that has high thermal resistance, low heat absorption rate, and high structural strength and that can catalyze hydrocarbon fuel and H2O evaporation. The specific surface structure and functional material thereof enable the present invention to reduce heat loss, lower CH, CO, and NO emission, and enhance thermal efficiency. |
