This utility model discloses a photovoltaic-thermal module for an evaporator, including a photovoltaic module, a heat absorber plate, a heat absorption channel, and a frame. A junction box is provided inside the photovoltaic module. The heat absorber plate is fixedly connected to the back of the photovoltaic module, and the heat absorption channel is fixedly connected to the heat absorber plate. Refrigerant circulates within the heat absorption channel. The heat absorption channel includes a manifold and branch pipes. The manifold has a closed design at both ends and is connected to a connecting pipe. The branch pipes are internally threaded thin tubes with a diameter of 3-10 mm. Both ends of the branch pipes are connected to the manifold, and one or more semi-circular bends are provided along the length of the same branch pipe. Using this photovoltaic-thermal module significantly reduces the risk of photovoltaic panel deformation and microcracks in the solar cells, simplifies the manufacturing process, reduces costs, and optimizes heat exchange efficiency.

The application discloses a prefabricated beam shared steel pedestal based on a standardized segment combination and a construction method, and relates to the technical field of bridge engineering prefabricated beam production. The application comprises a foundation support, a main frame and a top surface support. The foundation support is installed on a concrete cushion layer. The main frame is installed on the foundation support. The top surface support is installed on the main frame. The main frame comprises a T-beam pedestal and a box girder pedestal. The T-beam pedestal is connected with the box girder pedestal through flanges. The T-beam pedestal is used as a steel pedestal for T-beam prefabrication. The T-beam pedestal and the box girder pedestal are combined to be used as a steel pedestal for box girder prefabrication. The main frame is arranged to be the T-beam pedestal that can be used for T-beam prefabrication alone and the box girder pedestal that can be combined with the T-beam pedestal for box girder prefabrication. Therefore, the same set of steel pedestal systems can meet the prefabrication requirements of both T-beams and box girders, the versatility and adaptability of the pedestal are improved significantly, and the need for setting special pedestals for different beam types is reduced.
