The air precooler is required to be light and efficient. In order to meet the requirement of light weight, the air precooler adopts a micro tube bundle as a basic heat exchange unit; in order to achieve an efficient heat exchange effect, it is required that the thinner the wall thickness of the fine tube bundle is, the more preferable. Since a large number of bundles of fine tubes vibrate under the impact of air, and the like, the aspect ratio and amplitude of the bundles of fine tubes are large, and there is a problem of collision between bundles of fine tubes, a support structure is required between bundles of fine tubes. At present, the traditional tube type heat exchanger mostly adopts an orifice plate type supporting structure, and under the action of air flow, a micro tube bundle collides with a supporting orifice plate, so that the problem of cutting damage to an ultrathin and superfine micro tube exists.
