alternately disposed so that coolant can flow down along the core
tubes, exchanging heat between the coolant and the air.
[0061] A height of the radiator 2 is set to be larger than that of
the radiator core support 1, a distance between the upper member 11
and the lower member 12 thereof. Accordingly, the lower portion of
the radiator 2 emerges under the radiator core support 1 when they
are assembled with each other.
[0062] As shown in FIG. 4, there is shown the condenser 3. The
condenser 3 includes a left tank 31A, a right tank 31B, and a

[0072] In this embodiment, the elastic members 5A, 5B, 6A to 6C, 7A
and 7B are insulators made of synthetic rubber so as to absorb
vibration and attachment errors.
[0073] Next, how to build the heat exchanger support structure of
the embodiment will be described.
[0074] First, the radiator core support 1, the radiator 2, the
condenser 3 and the oil cooler 4 are provided.
[0075] The condenser 3 is mounted on the radiator 2 by inserting
the left and right supported pins 33A and 33B into the holes 28a
and 28b of the lower left and right brackets 28A and 28B of the
radiator 2 through not-shown elastic members, respectively. The
upper left and right brackets 32A and 32B of the condenser 3 are
arranged in front of the upper left and right brackets 27A and 27B
of the radiator 2 so that the holes 32a and 32b of the condenser 3
can lap on the holes 27a and 27b of the radiator 2, respectively.
The condenser 3 is fixed on the radiator 2 by not-shown nuts and
not-shown bolts penetrating the holes 27a, 27b, 32a and 32b.
[0076] Next, the radiator 2 and condenser 3 are attached to the
radiator core support 1, as shown in FIG. 1, by inserting the upper
left and right mounting pins 23A and 23B of the radiator 2 into the
holes 16a and 16b of the upper left and right brackets 16A and 16B
of the radiator core support 1 through the elastic members 5A and
5B, respectively. In addition, the intermediate left and right
brackets 24A and 24B of the radiator 2 are secured on the lower
left and right brackets 17A and 17B of the radiator core support 1
by not-shown bolts and nuts through not-shown elastic members,
respectively.
[0077] Then, the oil cooler 4 is attached to the radiator core
support 1 and the radiator 2, as shown in FIG. 7, by inserting the
lower left and right supporting pins 26A and 26B of the radiator 2
into the holes of the lower left and right brackets 42A and 42B of
the oil cooler 4 through the elastic members 7A and 7B,
respectively.
[0078] As shown in FIG. 1, the left, right and center welded bolts
18A, 18B and 18C of the radiator core support 1 are inserted into
the holes of the upper left, right and center brackets 41A, 41B and
41C of the oil cooler 4 through the elastic members 6A, 6B and 6C
and fastened by nuts 18a, 18b and 18c, respectively.
[0079] Note that the oil cooler 4 is supported by the radiator 2 so
that the lower left and right supporting pins 26A and 26B of the
radiator 2 restrict a horizontal movement of the oil cooler 4,
allowing a vertical movement thereof.
[0080] The radiator core support 1 with the radiator 2, the
condenser 3 and the oil cooler 4 is attached to the front part of
the vehicle body.
[0081] The heat exchanger structure of the embodiment has the
following advantages.
[0082] The oil cooler 4 can be supported by the radiator core
support 1 by bolts 18A to 18C and nuts 18a to 18c without
additional brackets fixed to the radiator core support 1,
decreasing the manufacturing process and manufacturing cost.
[0083] The lower portion of the oil cooler 4 is supported by the
lower left and right supporting pins 26A and 26B of the radiator 2
so that the lower left and right supporting pins 26A and 26B
restrict the horizontal movement of the oil cooler 4, allowing the
vertical movement thereof. This can decrease stress applied to the
lower tank 22 of the radiator 2. In addition, their assembly does
not need a fastening process using bolts and nuts. Therefore, the
manufacturing process and manufacturing cost can be reduced.
[0084] The lower left and right supporting pins 26A and 26B of the
radiator 2 are made of resin, which provides easy fracture of the
supporting pins 26A and 26B in a light bump, such as a bump where
an impact applied to a bumper pushes and moves the oil cooler 4
slightly rearward. Therefore, it can prevent the lower tank 22 of
the radiator 2 from fatal damage.
[0085] These supporting pins 26A and 26B and the lower tank 22 of
the radiator 2 are integrally formed of resin, which can decrease
the manufacturing process and manufacturing cost.
