Abstract: A mobile cooking-and-ingredient-supply system includes a vehicle, a data-storage device, a cooking module, an ingredient-supply rack, first-ingredient-supply modules, an ingredient-replenishing station and a computing device. The data-storage device stores a food-preparation plan associated with a food preparation location, a preparation time, and an ingredient for preparing a food product. The cooking module is configured to prepare the food product based on the food-preparation plan. The first-ingredient-supply modules are carried by the ingredient-supply rack. The ingredient-replenishing station carries second-ingredient-supply modules to meet with the vehicle and replenish one of the first-ingredient-supply modules.

Abstract: A multifunction flat plate heat exchanger including a heat exchanging flat plate, a spectrum selectivity absorption layer, a light transmissive layer, at least one heat-conductive structure, and at least one airflow driving device is provided. The heat exchanging flat plate has a first plate surface, a second plate surface and a pipe tunnel located between the first plate surface and the second plate surface. The spectrum selectivity absorption layer covers the first plate surface. The light transmissive layer covers the spectrum selectivity absorption layer, and the light transmissive layer and the first plate surface are respectively located at two opposite sides of the spectrum selectivity absorption layer. The heat-conductive structure is disposed on the second plate surface. The airflow driving device is disposed at one side of the heat exchanging flat plate and the heat-conductive structure.
