Abstract

<P>PROBLEM TO BE SOLVED: To prevent a width size of a connection part of a first heat exchange core and a second heat exchange core from becoming larger than a width size of the first heat exchange core or a width size of the second heat exchange core. <P>SOLUTION: A first reinforcement plate 2d of the first heat exchange core 2c, and a second reinforcement plate 3d of the second heat exchange core 3c are connected via a connection member 5 arranged between two wall surfaces 2e of the first reinforcement plate 2d, and two wall surfaces 3e of the second reinforcement plate 3d. By this, the maximum width size of the heat exchanger module 1 matches with width sizes of the first reinforcement plate 2d and the second reinforcement plate 3d, namely, the width sizes of the first heat exchange core 2c and the second heat exchange core 3c. Accordingly, since the maximum width size of the heat exchanger module 1 can be prevented from becoming larger than the width size of the first heat exchange core 2c or the width size of the second heat exchange core 3c, a width size of a cooling device including the heat exchanger module 1 and other heat exchangers can be reduced. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a heat exchanger module including a plurality of heat exchange cores.

  A heat exchanger such as a radiator or a condenser is generally composed of a plurality of tubes through which a fluid flows and fins provided on the outer surface of the tubes, and a reinforcing plate that reinforces the heat exchange core. (For example, refer to Patent Document 1).

Conventionally, a heat exchanger is assembled to a vehicle or the like by assembling one end of a metal bracket to a reinforcing plate with a bolt and the other end of the bracket to a vehicle body with a bolt.
Japanese Patent No. 3301158

  By the way, in recent years, a condenser and an oil cooler are integrated in a state where a condenser of a vehicle air conditioner and an oil cooler for cooling engine oil and ATF (automatic transmission fluid) are arranged in parallel to the air flow, or an engine. A radiator for (internal combustion engine), a traveling electric motor, and a radiator for cooling an inverter circuit for supplying driving current to the electric motor, etc. are integrated in parallel with the air flow. There is an increasing need for heat exchanger modules consisting of a single heat exchange core.

  Therefore, as shown in FIG. 12, the inventor fixes the reinforcing plate 2d of the first heat exchange core 2c and the bracket 10 with bolts 11 and nuts 11a, and the reinforcing plate 3d and the bracket 10 of the second heat exchange core 3c. And a heat exchanger module in which the bolt 12 and the nut 12a are fixed.

  However, in the heat exchanger module according to this examination product, the bolts 11 and 12 pass through the reinforcing plates 2d and 3d and the bracket 10 having a substantially U-shaped cross section. The large dimension, that is, the maximum dimension of the part parallel to the air flow direction in the heat exchanger module coincides with the total length of the bolts 11 and 12.

  That is, when the 1st heat exchange core 2c and the 2nd heat exchange core 3c are connected with the volt | bolt via the bracket 10, the maximum width dimension of a heat exchanger module will be the width dimension of the 1st heat exchange core 2c, or 2nd heat. It becomes larger than the width dimension of the exchange core 3c.

  And, for example, as shown in FIG. 13, when the heat exchanger module 1 and the other heat exchanger 4 are arranged in series with respect to the air flow, the heat exchanger module 1 and the other heat exchanger 4 It is necessary to provide a gap dimension d for preventing the interference between the two, but when the maximum width dimension A of the heat exchanger module 1 increases, the heat exchanger module 1 and the other heat exchanger 4 are included. The width dimension D of the heat exchanger becomes large.

  Further, in a vehicle, the heat exchange device including the heat exchanger module 1 and the other heat exchanger 4 is usually mounted on the front end portion of the vehicle, but the width dimension D of the heat exchange device is increased. As a result, it becomes difficult to secure a large space (crushable zone) for absorbing the collision force when the vehicle receives the collision force from the front side.

  Further, when the gap size between the heat exchange core of the heat exchanger module 1, that is, the first heat exchange core and the second heat exchange core, and the heat exchange core of the other heat exchanger 4 is increased, the heat exchange on the upstream side of the air flow is performed. The air passing through the core is a gap between the heat exchange core on the upstream side of the air flow and the heat exchange core on the downstream side of the air flow, that is, the heat exchange core of the heat exchanger module 1 and the heat exchange core of the other heat exchanger 4. There is a high risk that the air flow will flow downstream, bypassing the heat exchange core on the downstream side of the air flow.

  In other words, when the gap between the heat exchange core of the heat exchanger module 1 and the heat exchange core of the other heat exchanger 4 is increased, the amount of air supplied to the heat exchange core on the downstream side of the air flow is reduced. The capacity of the heat exchanger on the downstream side is reduced.

  In view of the above points, the present invention firstly provides a novel heat exchanger module different from the conventional one, and secondly, the maximum width dimension of the heat exchanger module is the width dimension of the first heat exchange core. Or it aims at preventing becoming larger than the width dimension of a 2nd heat exchange core.

  In order to achieve the above object, the present invention has a plurality of tubes (2a) through which fluid flows and fins (2b) provided on the outer surface of the tubes (2a). The first heat exchange core (2c) configured as described above and the end of the first heat exchange core (2c) are arranged to reinforce the first heat exchange core (2c) and face each other in the air flow direction. A first reinforcing plate (2d) having two wall surfaces (3e) and having a substantially U-shaped cross section, a plurality of tubes (3a) through which fluid flows, and an outer surface of the tube (3a) The second heat exchange core (3c) configured to have the provided fin (3b) and the second heat exchange core (3c) are disposed at the end of the second heat exchange core (3c) to reinforce the second heat exchange core (3c).

  Thereby, since the maximum width dimension of a heat exchanger module corresponds with the width dimension of a 1st reinforcement plate (2d) and a 2nd reinforcement plate (3d), the maximum width dimension of a heat exchanger module is 1st heat exchange. It can prevent becoming larger than the width dimension of a core (2c) or the width dimension of a 2nd heat exchange core (3c).

  According to a fourth aspect of the present invention, the fitting portion between the engagement protrusion (5d, 5e) and the engagement hole (2h, 3h) is filled with an adhesive or a curing agent. .

  Thereby, the engagement protrusions (5d, 5e) and the engagement holes (2h, 3h) can be firmly engaged.
