This application relates to a heat exchanger and a thermal management system. The heat exchanger includes a flow guide plate with first flow guide grooves. Adjacent first flow guide grooves form multiple flow splitting gaps. The first flow guide groove is formed by either a straight groove segment or a curved groove segment alone, or by alternating arrangements of both. The straight groove segment includes multiple staggered channels connected sequentially along its own centerline, with adjacent staggered channels arranged in a direction perpendicular to the centerline of the straight groove segment. The flow guide plate also has multiple second flow guide grooves and flow guide protrusions. The flow guide protrusions divide the area of ​​the cold flow channel layer between the first and second flow guide grooves into multiple flow guide channels. The flow area of ​​the flow guide channels, the flow area of ​​the first flow guide groove, and the flow area of ​​the second flow guide groove are all equal. The heat exchanger and thermal management system provided by this application solve the problem of thermal stress concentration in the heat exchanger caused by inconsistent heat exchange effects at different locations in the cold flow channel layer.

The invention provides a silo flow changing device. The problem that the flow changing performance of a circular truncated cone type flow changing device cannot be adjusted is solved. The silo comprises a silo body, the lower end of the silo body is of a conical barrel structure with the diameter gradually reduced downwards, and a discharging opening for communicating the inside and the outside is formed in the bottom of the silo body; a hollow interlayer which extends in the vertical direction and is communicated end to end in the horizontal direction is arranged in the side wall of the silo, and a plurality of ventilation holes communicated with the hollow interlayer are formed in the outer side wall of the silo; a plurality of fans are arranged on the outer side wall of the silo, the fans are in control connection with the controller, and an air outlet of each fan communicates with the end, away from the hollow interlayer, of the corresponding ventilation hole; a distribution pipe communicated with the ventilation holes is fixedly arranged in the hollow interlayer; the bottom of the distribution pipe is provided with a plurality of first air supply pipes which are arranged at intervals in the circumferential direction of the distribution pipe and extend towards the lower portion of the distribution pipe, the first air supply pipes are connected with second air supply pipes, and the ends, away from the first air supply pipes, of the second air supply pipes penetrate into the silo and are connected with the air inlet end of the pneumatic flow changing device.

The application discloses an air-laid machine for uniform netting, comprising a frame for providing a supporting installation reference; a cotton feeding unit arranged at one end of the frame for continuously outputting fiber raw materials; and a conveying netting unit arranged at the other end of the frame for providing a bearing surface for fiber netting and conveying a formed fiber net. The application divides the flow guide channel into an upper flow section, a middle flow section and a lower flow section, and sets a fiber guide component in the middle flow section to form a multi-stage continuous fiber guide channel. When the mixed fiber raw materials flow along the flow guide channel, the fiber guide channel can first guide and converge part of the layered fiber raw materials, and then perform secondary deviation correction on the outflow part of the layered fiber raw materials, so that full coverage and continuous guidance mixing of the layered fiber raw materials are realized. Meanwhile, the staggered interval type channel structure of the fiber guide channel will not block the airflow, can effectively avoid the retention, wall-hanging accumulation and channel blockage of the fiber raw materials, and continuously ensures the uniform and stable flow of the fiber airflow.
