A set of water-cooled radiator was designed to control the operating temperature of photovoltaic cell. The variation law of cell temperature and pressure loss of radiator under different water flow rate and the corresponding output characteristic of photovoltaic cell were studied. The experiment shows that the temperature of radiator is 1 373K, The battery temperature is 302 K at 25 mL / s. The designed radiator can effectively control the temperature of the photovoltaic cell. Using the Fluent software, the structural parameters such as the height of the guide vane, the number of guide vanes and the diameter of the cooling water inlet and outlet pipes were analyzed. The calculation results show that increasing the diameter of cooling water inlet and outlet can effectively reduce the pressure loss without affecting the heat dissipation effect. The numerical simulation results are in good agreement with the experimental results, which proves the correctness of the numerical simulation method.
