PROBLEM TO BE SOLVED: To provide a heat collection receiver capable of efficiently recovering energy from the heat collection receiver in which energy concentration of sunlight is not uniform.SOLUTION: A central portion of an irradiated face to which sunlight SB is irradiated, of an absorber 10A is formed by an outer end face 221 of a first honeycomb body 22, and a circumferential portion surrounding the central portion is formed by an outer end face 231 of a second honeycomb body 23. Ventilation resistance of a second honeycomb body flow channel 232 in the second honeycomb body 23 is higher than ventilation resistance of a first honeycomb body flow channel 222 in the first honeycomb body 22. Thus lowering of a temperature of sucked air is prevented, and energy can be efficiently recovered from a heat collection receiver 10A in which energy concentration of the sunlight SB is not uniform.SELECTED DRAWING: Figure 5 |
