Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat exchanger for a vehicle in which a heat exchanger and a blower are unitized.

[0002]

2. Description of the Related Art In general, a vehicle heat exchanger device includes means for fixing a blower to a heat exchanger (radiator) with bolts, and assembling the heat exchanger to which the blower is fixed to a vehicle via a bracket (see FIG. 1). JP-A-5-2446).

[0003]

In recent years, front-wheel drive vehicles (so-called FF vehicles) have been increasing in order to expand the vehicle interior space while suppressing an increase in vehicle external dimensions. In general, in FF vehicles, means for reducing engine vibration by using a radiator as a balance weight (balance weight) at a resonance frequency corresponding to the vibration frequency of the engine is employed.

For this reason, in the above-mentioned means, the radiator is subjected to a vibrating force due to its own weight in addition to the vibrating force due to its own weight, so that the radiator needs to have mechanical strength capable of withstanding these vibrating forces. Therefore, the size of the radiator is increased. The present invention has been made in view of the above circumstances, and has as its object to provide a heat exchanger device for a vehicle in which a heat exchanger such as a radiator is prevented from being enlarged.

In the above description, the problem of the present invention has been described using an FF vehicle as an example. However, in a vehicle heat exchanger, an exciting force acts due to engine vibration or the like. But that's a problem.

[0006]

The present invention uses the following technical means to achieve the above object. Claim 1
In the invention described in Item 3, the heat exchanger (HE) and the blower (1
50) and the reinforcing member (130).
It is characterized by comprising a vehicle fixing part (141) fixed to the vehicle and a bracket part (140) having a blower fixing part (142) to which the blower (150) is fixed.
Thereby, the blower (150) is connected to the bracket (14).
0) via a heat exchanger (H)
E) also has a structure that is fixed to the vehicle via the bracket portion (140). Therefore, the heat exchanger (HE) has a structure in which the vibrating force due to the weight of the blower (150) hardly acts on the heat exchanger (HE). Therefore, it is not necessary to excessively increase the mechanical strength of the heat exchanger (HE). It is possible to prevent an increase in the size of the heat exchange device for use.

In the present invention, since the blower (150) is a simple means such as fixing the blower (150) to the bracket portion (140), the manufacturing cost of the vehicle heat exchange device can be prevented from increasing and the heat exchange device for the vehicle can be prevented. Enlargement can be prevented. In addition, as in the invention described in claim 2, the blower (1
50) may be fixed to the blower fixing part (142) via the shroud part (151).

Further, the bracket part (140) and the shroud part (151) may be integrally formed of resin. In addition, the code | symbol in the parenthesis of each said means shows the correspondence with the concrete means of embodiment mentioned later.

A cylindrical pin portion (vehicle fixing portion) 141 that is inserted into and fixed to the vehicle is integrally formed. Also, 1
Reference numeral 50 denotes a blower disposed on the radiator core 110 side for blowing air to the multiple heat exchange core 100. The blower 150 is assembled to the shroud 151. And the shroud part 151 covers the gap between the blower 150 and the multiple heat exchange core 100 (vehicle heat exchanger HE),
In addition to increasing the amount of air flowing through the duplex heat exchange core 100, it also serves as a stay member for fixing the blower 150 to the bracket 140.

On the other hand, the side plate 130 and the bracket portion 140 have insertion holes 1 into which bolts 160 are inserted.
