Cover structure for heat exchanger having resinous tank

摘要

In a cover structure for restricting adhesion of foreign materials such as an antifreezing agent to a resinous tank of a heat exchanger, a cover member is arranged such that its first end is in the proximity of a boundary between a core portion and the resinous tank of the heat exchanger and its second end is adjacent to an opening through which air is introduced. The cover member blocks the foreign materials entering from the opening and restricts. Also, the cover member directs the air having passed through the opening toward the core portion. Thus, the tank is less likely to deteriorate due to adhesion of the foreign materials. Further, efficiency of heat exchange of the core portion improves.
