2. Description of the Related Art Hitherto, vehicles such as trucks equipped with a freezer and a refrigerating device for cooling the freezer have been known. And as one of such trucks, the evaporator unit of the refrigeration system is provided in the freezer, and the condensing unit is outside the freezer, for example,
It is also known to be mounted on the roof of the driver's seat or on the roof.

An example of such a roof-mounted condensing unit will be described with reference to FIG. 1. A condensing unit indicated generally by reference numeral 1 is provided on a truck roof 2 as described above. . The condensing unit 1 has an engine 2 dedicated to a refrigeration system. The engine 2 is drivingly connected to a compressor 3 and a condenser fan 4. The condensing unit 1 also has a motor 5 and an alternator 6 drivingly connected to the motor 5, and the alternator 6 is electrically connected to the engine 2 and an evaporator fan (not shown) of the evaporator unit. I have.

[0007]

Since the refrigeration system is mounted on a vehicle, the heavier the refrigeration system, the smaller the amount of luggage that can be loaded on the freezer. Fuel economy will be worsened.

[0008] Therefore, as part of the weight reduction of the refrigeration system,
Conventionally, support frames 13, 1
An attempt was made to reduce the thickness of 5 and 16.

Thus, the condenser 7 is connected to the support frame 1.
3, 15, 16, so that there is an input to the vehicle from the road while the vehicle is running, or
Vibrates, the support frames 13, 15, 16 are vibrated, and the capacitor 7 attached thereto is also vibrated, but the vibration of the capacitor 7 on the other hand causes the support frames 13, 15, 16 to cycle at a high cycle. You will be tired.

However, if the support frames 13, 15, 16 exposed to high cycle fatigue are thinned as described above, the support frames 13, 15, 16 may be cracked. , 1
6 could be damaged.

For the same reason, when the side plates 9, the partition plate 10, and the back plate 11 of the capacitor 7 are thinned for the purpose of weight reduction, these support plates may be damaged.

Preferably, the flexible tube of the outlet tube is connected to a discharge tube extending from the receiver.

[0016]

An embodiment of the present invention will be described below with reference to the accompanying drawings. In the present embodiment, the present invention is applied to a condenser of a condensing unit of a refrigerating apparatus mounted on a roof of a driver's seat of a truck.

Referring to FIG. 5, the capacitor of the present invention is indicated generally by the reference numeral 20. This capacitor 20 has a capacitor body 21 and a capacitor body 21.
Are provided with side plates 22 at both ends thereof. The upper end and the lower end of each side plate 22 are bent away from the capacitor body 21, that is, bent outward to form the mounting portions 23 and 24. Each of the mounting portions 23 and 24 has a mounting through hole (not shown).

Each lower mounting portion 24 is fixed to a lower horizontal support frame 26 via a vibration isolating member 25. The lower horizontal support frame 26 is fixed to the bottom wall (not shown) of the housing (not shown) of the condensing unit, and the housing (not shown) itself, in a suitable manner, Attached to.

The anti-vibration member 25 is mounted on the lower horizontal support frame 2.
6 has a bracket portion 27 to be bolted, and a bolt through hole (not shown) is formed in the bracket portion 27. An elastic part 28 is also fixed to the bracket part 27,
In the present embodiment, the elastic portion 28 is made of rubber. A support plate 29 is further fixed to the elastic portion 28, and the support plate 29 has a threaded shaft 30 extending away from the elastic portion 28.

Each upper mounting portion 23 of the capacitor body 21 is fixed to a top wall 32 of the housing (not shown) of the condensing unit via a vibration isolating member 33.

The vibration isolating member 33 has an elastic portion 34, which in this embodiment is made of rubber. A support plate 35 is fixed to the elastic portion 34, and the support plate 35 has a threaded shaft 36 extending away from the elastic portion 34.

The upper mounting portion 23 of the capacitor body 21 is fixed to the top wall 32 of the housing (not shown) via the vibration isolating member 33, and the lower mounting portions 24 of the capacitor body 21 are fixed.
In order to fix to the lower horizontal support frame 26 via the anti-vibration member 25, first, the anti-vibration members 25 and 33 are attached to the lower mounting portion 24 and the upper mounting portion 23, respectively.

The vibration isolating member 33 is attached to the upper mounting portion 23 by passing a threaded shaft 36 of the vibration isolating member 33 through a mounting through hole (not shown) of the upper mounting portion 23 from above. This is achieved by threading a nut 37 onto a threaded shaft 36 projecting downward from the part 23. Similarly, the vibration isolating member 25 is attached to the lower mounting portion 24 by passing the threaded shaft 30 of the vibration isolating member 25 through a mounting through hole (not shown) of the lower mounting portion 24 from below. This is done by screwing a nut 31 onto a threaded shaft 30 projecting upward from the part 24.

Next, with an upward force applied to the capacitor body 21 so that the vibration isolating member 33 abuts on the top wall 32, the bolt through hole of the bracket portion 27 of the vibration isolating member 25 is formed.
Screw holes (not shown) formed in the horizontal support frame 26
(Not shown), and bolts (not shown)
5 is screwed into a screw hole (not shown) of the horizontal support frame 26 through a bolt through hole (not shown) of the bracket portion 27.

The condenser body 21 also has an inflow pipe 40 having a flexible tube 41 at the tip and an outflow pipe 42 having a flexible tube 43 at the tip.
The flexible tube 41 is connected to a rigid supply pipe 44 extending from a compressor C for increasing the pressure and temperature of the refrigerant, and the flexible tube 43 of the outlet pipe 42 is rigidly connected to a rigid tank extending from a liquid tank or receiver R. Connected to the discharge pipe 45. Both flexible tubes 41, 43 function to compensate for displacement of the capacitor body 21 that occurs during vibration. That is, when the vehicle vibrates, the capacitor main body 21 supported by the vibration isolating members 25 and 33 having the elastic portions 28 and 34 moves up and down, and is displaced with respect to the rigid tubes 44 and 45 whose positions are fixed. When the flexible tubes 41 and 43 flex, the inflow pipe 40 and the outflow pipe 4
2 and / or prevent the supply pipe 44 and the discharge pipe 45 from being damaged.

The present invention is not limited to the embodiments described above, and various changes can be made.

For example, in the above embodiment, the vibration isolator 25
Although the bracket portion 27 is bolted to the lower horizontal support frame 26 and the support plate 29 is fixed to the lower mounting portion 24 with a nut, the vibration isolating member is connected to the lower mounting portion 24 via this. Should be attached to the lower horizontal support frame 26, for example,
The vibration isolating member may be constituted only by the elastic body having the through passage. In this case, for example, the lower horizontal support frame 26
A bolt is passed through the mounting hole of the lower horizontal support frame 26 from below, and a bolt that projects upward from the lower horizontal support frame 26 is provided with a through passage of the vibration isolating member. It may be tightened with a nut through the mounting through hole.

In the above embodiment, the capacitor body 21 is attached to the housing (top wall 32, frame 26) of the condensing unit, but can also be attached directly to any part of the vehicle.

Further, in the above embodiment, the flexible tubes 41 and 43 are connected to the supply pipe 44 and the discharge pipe 45, respectively, but the flexible tubes 41 and 43 are connected to the compressor C and the receiver, respectively. It may be connected to R.
