The invention relates to the technical field of photovoltaic cells, and discloses a high-efficiency photovoltaic cell equipment water-cooling radiator which comprises a shell, a heat exchange tube is fixedly connected in the shell, a rotating rod is rotatably connected in the heat exchange tube, and a plurality of driving blades are fixedly connected to the outer side of a rod body of the rotating rod. The top ends of the multiple rotating rods penetrate through the heat exchange pipe and are fixedly connected with a cooling fan. According to the invention, firstly, the pump body is started to enable water flow to pass through the interior of the heat exchange pipe and take away heat dissipated by the device, and the water flow is further utilized to impact the driving blade, so that the heat dissipation fan can rotate and dissipate heat of the heat exchange pipe and water in the heat exchange pipe at the same time, thereby achieving the purpose of dissipating heat of cold water of the ...

The invention discloses a medium-and-high curve, current-voltage curve (CVC) and arbitrary curve grinding device for a roller grinder. The device is arranged in a grinding frame; a grinding wheel (1) is arranged on the front part of a shell (2) on the grinding frame; a rolling wheel (12) is connected with a rolling wheel seat (13) through a rotary shaft (14), and is fixed in the shell (2) on the grinding frame; a bearing seat (8), a linear rolling guide rail (9) and a support (10) are arranged on the top surface of a shell (11) below the grinding frame respectively; and a motor (6) is used for driving a ball screw (3) to rotate through a speed reducer (7) and driving a sliding oblique block (4) to slide back and forth along the linear rolling guide rail (9). Through the movement of the sliding oblique block (4), the shell (2) on the grinding frame is swung up and down around a point O, so that the grinding wheel (1) is driven forwards or is retreated, and the requirement that a medium-and-high ...
