Abstract
A heat intensifier for directing radiant heat from a campfire toward a camper situated on the ground adjacent the campfire to enhance the warmth provided by the campfire to the camper includes a collapsible screen having a heat-reflective surface and a frame for attachment to the screen to deploy the screen in a concave-convex configuration in which the heat-reflective surface is located in a position relative to the camper and the campfire to reflect radiated heat from the campfire toward the camper, and anchoring devices for anchoring the attached screen and frame to the ground in that position.
