Research of Flow Field for Irradiation Box of Cable Ultraviolet Cross-Linking

In order to analyze the cooling air velocity and pressure distribution characteristics in a ventilation scheme presented for the irradiation box of cable ultraviolet cross-linking, the three-dimensional solid model of the irradiation box was established, its flow field was simulated by software FLUENT according to computational fluid dynamics principle under some calculation conditions. The results show that the air velocity around the cable is higher, enhancing convective heat transfer effect, the irradiation box large space is under negative pressure condition.
