Description

  The present invention relates to a vehicle air guide structure that guides outside air introduced from a vent of a bumper to a heat exchanger such as an air conditioning condenser or a radiator using an air guide.

  In vehicle body structures such as automobiles, an air guide such as a seal member is interposed between a bumper and a heat exchanger such as a condenser for air conditioning or a radiator, and outside air introduced from the vent of the bumper is removed. There is provided a guide for a heat exchanger. By adopting such an air guide structure, the taken-in outside air can be efficiently guided to the heat exchanger, so that heat exchange between the outside air and the refrigerant in the heat exchanger can be promoted.

Utility Model Registration No. 2502184 JP 2003-306047 A JP 2008-120369 A

  Here, in the conventional vehicle air guide structure, in order to improve the sealing performance against the introduced outside air, the air guide is formed of an elastic material, and the front end portion of the air guide is in close contact with the edge of the air vent. In addition, the rear end of the air guide is brought into close contact with the edge of the heat exchanger and the periphery thereof.

  By the way, in the conventional vehicle air guide structure, the material of the air guide is lightweight, such as sponge material, for the purpose of reducing the weight, reducing the cost, and improving the adhesion with the bumper. In some cases, a relatively flexible material is used.

  However, if the material as described above is adopted as the material of the air guide, the air guide cannot be fixed to the heat exchanger using a fixing member or the like. It had to be fixed to a heat exchanger using This complicates the installation work of the air guide and causes a problem that the number of installation work steps greatly increases.

  Further, in the conventional vehicle air guide structure, when the distance between the vent of the bumper and the heat exchanger is increased, the length of the air guide must be increased accordingly. When the air guide is formed by using this, it is difficult to ensure the rigidity of the air guide itself. This not only makes the mounting operation described above more complicated, but also causes the air guide to fall, turn over, peel off, etc. depending on the magnitude of the wind pressure of the outside air, thereby reducing its sealing performance. As a result, there is a possibility that the wind guide property as the vehicle air guide structure is lowered.
