The invention provides a cooler used for a vehicle-mounted transformer and provided with a sub-cavity and a railway vehicle. A shell of the cooler is provided with a cooler liquid inlet and a cooler liquid outlet. The interior of the cooling liquid shell is divided into K1 + 1 sub-cavities, the first sub-cavity is provided with a cooling liquid inlet connected with a cooler liquid inlet, the (K1 + 1) th sub-cavity is provided with a cooling liquid outlet connected with a cooler liquid outlet, the ith sub-cavity is connected with the (i + 1) th sub-cavity through the ith cooling pipe set, and the (i + 1) th sub-cavity is connected with the (i + 1) th sub-cavity through the (i + 1) th cooling pipe set. Therefore, the cooler liquid inlet, the first sub-cavity, the second sub-cavity,..., the (K1 + 1) th sub-cavity and the cooler liquid outlet are communicated in sequence; each cooling pipe in the ith cooling pipe group is arranged between the ith area and the (i + 1) th area in a crossing manner; at least part of each cooling pipe in the cooling pipe set is located on the outer side of the cooler shell.

    本发明提供一种用于车载变压器且具有子腔体的冷却器及轨道车辆,所述冷却器的壳体具有冷却器进液口、冷却器出液口;所述冷却液的壳体中分隔形成K1+1个子腔体,第1个子腔体具有与冷却器进液口连接的冷却液入口,第K1+1个子腔体具有与冷却器出液口连接的冷却液出口,第i个子腔体通过第i个冷却管组与第i+1个子腔体连接,从而使得冷却器进液口、第1个子腔体、第2个子腔体、……、第K1+1个子腔体、冷却器出液口依次连通;其中,第i个冷却管组中的各个冷却管跨设在第i个区域、第i+1个区域之间;冷却管组中每个冷却管的至少部分位于冷却器壳体外侧。
