Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a refrigeration unit mounted on a vehicle body.
The present invention relates to a transportation refrigerating / refrigerating apparatus in which a refrigerating machine is driven by a sub-engine provided separately from a running engine.

[0002]

2. Description of the Related Art An example of a conventional transportation refrigerating / refrigerating apparatus is shown in FIG. In FIG. 2, reference numeral 100 is a vehicle body, 101 is a chassis portion, and 1 is a condensing unit, which is installed on one side of the center S in the vehicle width direction.

The condensing unit 1 contains a sub-engine 2, a refrigerant compressor 4, a motor 3, a heat exchanger 5 such as a condenser, and accessories such as a fan and a refrigerant pipe. The evaporator is arranged in the freezer / refrigerator.

The condensing unit 1 contains heavy components such as the sub-engine 2, the motor 3, the refrigerant compressor 4 and the heat exchanger 5 and accessories such as fans and refrigerant pipes. Usually reaches over 600 Kg. Moreover, in recent years, the size of vehicles has increased, and this tendency is becoming more prominent as the loading capacity of the vehicles increases.

[0005]

In the above conventional refrigerating / refrigerating apparatus, since the sub-engine 2 has a large self-exciting force, its mounting frame requires a sufficient vibration resistance, so that it has a strong structure. It is necessary to increase the weight.

Since the heavy condensing unit 1 is installed on one side of the vehicle body 100, that is, on one side with respect to the center S in the vehicle width direction, the weight balance of the vehicle is deteriorated and the vibration of the vehicle body is amplified. There is a risk.

[0007]

SUMMARY OF THE INVENTION The present invention has been invented to solve the above problems, and its gist is to provide a transportation system in which a refrigerating / refrigerating device mounted on a vehicle body is driven by a sub engine. In the refrigerating / refrigerating machine for use, the heat exchanger of the refrigerating / refrigerating equipment is housed in the heat exchanger housing, and the power equipment such as the sub-engine, motor, refrigerant compressor is housed in the power package, and Refrigeration for transportation characterized in that the container compartment and the power package are separated and installed on both sides with respect to the center of the vehicle width direction.
Located in the refrigerator.

[0008]

In the present invention, since it has the above-mentioned structure, only the power package portion in which the power equipment having the self-exciting force is housed has to have the strong structure having the vibration-proof structure. Since the heat exchanger housing does not require a special vibration-proof structure, the structure can be thin, lightweight and simple.

Further, since the power package part and the heat exchanger storage part are installed on both sides with respect to the center of the vehicle body in the vehicle width direction,
The left-right weight balance of the vehicle is improved, and vibration due to weight imbalance is prevented.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIG. 1, where (A) is a side view of a vehicle, (B) is a view taken along the arrow B of (A), and (C) is a power package part. External view, (D) is an external view of the heat exchanger housing.

In FIG. 1, reference numeral 100 is a vehicle body, 101 is a chassis portion, 103 is wheels, 10 is a power package portion, and 11 is a heat exchanger housing portion.

As shown in (C), the power package unit 10 houses power equipment such as the sub-engine 2, the motor 3, the refrigerant compressor 4, etc., and the heat exchanger housing unit 11 stores in (D). As shown, a heat exchanger 5 such as a condenser and a fan 6, accessories such as a refrigerant pipe are stored.

The power package portion 10 and the heat exchanger housing portion 11 are hung on the vehicle body 100 on the left and right sides with respect to the center S in the vehicle width direction, separated from each other between the front and rear wheels 103, that is, in the middle of the wheel base. It is installed by.

Since the power package portion 10 is separated from the heat exchanger housing portion 11, the size thereof can be about 2/3 of that of the conventional condensing unit 1. It suffices if only the power package 10 has a vibration resistant structure against the self-exciting force of the sub-engine 2, the motor 3 and the refrigerant compressor 4. The heat exchanger housing portion 11 does not need any particular vibration resistance strength except for considering the vibration during traveling of the vehicle, and thus can be made thin and lightweight.

Therefore, the total weight of the power package 10 and the heat exchanger housing 11 can be reduced by about 10% as compared with the conventional condensing unit 1 shown in FIG. Further, the power package portion 10 and the heat exchanger storage portion 11 are located at the center S in the vehicle width direction.
With respect to the left and right sides, the left and right weight balances are improved as compared with the conventional one shown in FIG. 2, and the occurrence of vehicle body vibration due to the weight imbalance can be prevented.

[0016]

According to the present invention, since the heat exchanger of the refrigerating / refrigerating equipment is housed in the heat exchanger housing portion and the power equipment such as the sub-engine, the motor and the refrigerant compressor is housed in the power package portion, It suffices to have a strong vibration-proof structure only in the power package part in which the power equipment having an exciting force is housed. And since the heat exchanger housing does not require any particular strength, it can be made thin and lightweight and simple in structure, so the weight of the refrigerating / refrigerating device should be greatly reduced compared to the conventional one. You can Furthermore, since the heat exchanger, which requires a large space, is stored in the heat exchanger storage part separately from the power equipment, the overall size of the device can be made smaller than the conventional one, which contributes to downsizing and compacting. You can Further, since the power package part and the heat exchanger housing part are installed separately on both sides with respect to the center in the vehicle width direction, the left and right weight balance of the vehicle is improved, and the occurrence of vehicle body vibration due to the weight imbalance can be prevented. .
