ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a connecting structure for connecting a radiator and condenser.
The present application is based on Japanese Patent Application No. Hei. 10-215089, which is incorporated herein by reference.
2. Description of the Related Art
A conventionally known connecting structure for connecting a radiator and a condenser is described in Japanese Utility Model Publication No. Sho. 59-130987.
FIG. 12
shows a connecting structure disclosed in the publication, and in this connecting structure, a condenser
1
and a radiator
2
are arranged at a predetermined interval.
In addition, a spacer
5
is disposed between a cooling air guide
3
of the condenser
1
and a reinforce
4
of the radiator
2
, and a bolt
6
is put through them. A nut
7
is then screwed onto a tip of the bolt, whereby the condenser
1
and the radiator
2
are connected to each other.
With the aforesaid conventional connecting structure for connecting a radiator and a condenser, however, since the condenser
1
is connected only to a folded portion
4
a
formed on one side of the reinforce
4
of the radiator
2
via the spacer
5
, there is caused a risk of the folded portion
4
a
being deformed, thus leading to a problem that a sufficient connecting strength cannot be obtained.
SUMMARY OF THE INVENTION
The present invention was made to solve the above problem, and an object thereof is to provide a connecting structure for connecting a radiator and a condenser in which a condenser can be connected to a reinforce of a radiator easily and securely.
According to the present invention, there is provided a connecting structure for connecting a radiator and a condenser by connecting a bracket fixed to a tank of the condenser with a reinforce having a U-shaped cross-section and disposed on both sides of a core of the radiator by a connecting member. A notch is formed in the connecting member, a spacer portion is integrally formed on one side of the notch, and a supportingly holding portion is integrally formed on the other side of the notch. The spacer portion is fittingly inserted into the reinforce and a folded portion of the reinforce situated on the side thereof facing the condenser and the bracket are fittingly inserted into the notch. A bolt is put through the reinforce, the spacer portion, the bracket and the supportingly holding portion, and a nut is screwed onto a tip of the bolt for clamping the radiator and the condenser together.
In the connecting member, a recessed portion may be formed on the supportingly holding portion, and the bracket is fittingly inserted into a recessed portion formed on the supportingly holding portion.
Preferably, a nut receiving portion for receiving the nut in such a manner as to prohibit the rotation of the nut therein is integrally formed on an external side of the supportingly holding portion of the connecting member.
Preferably, a locking pawl is formed in the connecting portion which is adapted to be locked in a locking hole formed in the reinforce.
In a connecting structure for connecting a radiator and a condenser according to the present invention, the radiator and the condenser are connected to each other by fittingly inserting the spacer portion of the connecting member into the reinforce by meshing the folded portion of the reinforce situated on the side of the condenser in the notch, then fittingly inserting the bracket into the notch on the side thereof facing the supportingly holding portion, thereafter allowing the bolt to be put through the reinforce, the spacer portion, the bracket and the supportingly holding portion, and screwing the nut onto the tip of the bolt for clamping the radiator and the condenser together.
Preferably, the radiator and the condenser are connected to each other by fittingly inserting the spacer portion of the connecting member into the reinforce by fittingly meshing the folded portion of the reinforce situated on the side thereof facing the condenser in the notch, then fittingly inserting the bracket into the recessed portion of the supportingly holding portion, thereafter allowing the bolt to be put through the reinforce, the spacer portion, the supportingly holding portion and the bracket and screwing the nut onto the tip of the bolt for clamping the radiator and the condenser together.
Preferably, the nut receiving portion for receiving a nut in such a manner as to prohibit the rotation of the nut therein is integrally formed on the external side of the supportingly holding portion of the connecting member.
Preferably, when the spacer portion of the connecting member is fittingly inserted into the reinforce, the locking pawl of the connecting member is locked in the locking hole formed in the reinforce.
