The invention discloses a temperature control integrated focal plane assembly suitable for a space remote sensing camera, and the assembly comprises a temperature control substrate which is provided with two installation surfaces, the two installation surfaces can conduct heat and are provided with a reinforcing structure, and the interior of the temperature control substrate is filled with a phase change material; the fixed seat is fixed on the temperature control substrate through a gasket, a heat conduction layer is arranged between the fixed seat and the gasket, a heat conduction layer is arranged between the temperature control substrate and the gasket, and a detector is fixedly connected to the fixed seat; and the structure of the hold-down part corresponds to that of the fixed seat, and the hold-down part can be detachably held down on the detector. According to the invention, the temperature control capability of the focal plane substrate is improved in principle, the device is suitable for heat dissipation of a high-power-consumption detector or a focal plane assembly which is large in thermal control design difficulty and limited in thermal control implementation space, and compared with a common solid-liquid phase change heat pipe, the contact thermal resistance is reduced, and the heat conduction efficiency is improved.
