The utility model discloses a three-dimensional warm-keeping shoulder pad, and relates to the field of garment shoulder pads. Comprising a surface layer fabric, a first liner cloth, a first down filling area, a second liner cloth, a third liner cloth, a second down filling area and a heating silver coating fabric which are sequentially distributed from outside to inside; the first down filling area and the second down filling area are filled with down. The three-dimensional warm-keeping shoulder pad can be sewn on the shoulder area of a down jacket, adopts an arc-shaped structure with a narrow upper part and a wide lower part, fits the shoulder joint of a human body, is attractive and comfortable, and conforms to the movement range of the human body; a multi-layer structure is arranged, and the layout is reasonable; wherein the shoulder down filling area is independently divided, the area is small, the situation that warm-keeping down feather falls and deviates is effectively prevented, and then the shoulder warm-keeping effect is improved; the three-dimensional warm-keeping shoulder pad is provided with the heating silver coating, heat energy of a human body can be reflected, infrared heat loss is reduced, circulating temperature locking and efficient heat gathering are achieved, the heat preservation performance is improved, and meanwhile the static electricity eliminating effect is achieved.

The utility model relates to the technical field of flue gas waste heat recovery, disclose a kind of flue gas waste heat recovery energy-saving device, including heating system and circulation system, the heating system includes ramming coke oven, tubular heat exchanger, hot oil tank and reboiler, and the ramming coke oven is connected with tubular heat exchanger by waste heat gas collector intercommunication, and the hot oil tank is communicated with tubular heat exchanger bottom, and the tubular heat exchanger top is communicated with reboiler side;The circulation system includes the cooling equipment, cooling medium pump, cooling medium storage tank of circulation intercommunication, and the cooling equipment side is communicated with reboiler, with the effect that the heat energy in the high-temperature flue gas generated in coke oven production process is effectively recycled.

The invention discloses a large-size flat-plate solar collector, and belongs to the technical field of solar collectors. Comprising an outer shell, and a glass cover plate is fixed to the front side of the outer shell; a heat absorption unit is arranged on the inner side of the outer shell, and a heat collection pipe set connected with the heat absorption unit is arranged on the outer shell. The heat collecting pipe group is connected to the heat storage unit; the heat absorption unit comprises a heat absorption plate, a first flow channel unit, a second flow channel unit, an aluminum foil air bag unit and a supporting heat preservation unit, and a plurality of heat exchange grooves are pressed in the heat absorption plate at intervals; the first flow channel unit comprises flow channel branch pipes which are pressed and welded in the heat exchange grooves, and the two ends of each flow channel branch pipe are connected to the upper collecting pipe and the lower collecting pipe through transition parts correspondingly; according to the large-size flat-plate solar collector, heat can be continuously collected in a low-temperature state, heat energy of heat collection can be fully utilized, and more energy is saved in use.
