Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention enables a container used in rail transportation to be refrigerated and frozen.

(B) Prior Art Conventionally, an apparatus that enables refrigerating and freezing transportation for container vessels in ship transportation has been known.

However, since the refrigerating and freezing container for shipping the ship can use the electric power generated by the auxiliary equipment of the ship, in order to drive the refrigerant cooling unit attached to the container,
Power can be supplied simply by inserting a 200-volt plug into the outlet provided on the container.

However, in the case of the container for the ship, there is almost no loading and unloading of the container, and it is mainly stored in a refrigerated freezer before and after unloading, and the container is left alone. It is possible to rely on the external power source in this way because it is rare that it will be in a standing state.

(C) Problems to be solved by the invention However, in the case of rail transportation, power supply to drive the refrigerant cooling unit in the container tower freight car is not easy,
In addition, it is transported in the country in a short period of about 1 to 3 days, and loading and unloading is frequent, and it is often left near the station after being unloaded from the container tower freight car. It is necessary to attach an engine as a power source.

Then, it is necessary to drive the generator by the engine to generate electric power and cool the refrigerant cooling unit while controlling the temperature.

Therefore, when the engine continues to rotate, engine noise and compressor noise are constantly generated as noise from the container, and it is necessary to keep these noises as low as possible.

Further, even when the containers are left in the cooled state, the containers are stacked, so that it is necessary to sufficiently cool the engine and the compressor in the state.

 The present invention improves on this point.

(D) Means for Solving the Problems The object and the structure of the present invention are as described above. Next, the structure for achieving the object will be described.

A condensing chamber e and an engine chamber a are arranged on a panel 22 provided on the side surface of the container 21.
A passage port K for introducing cooling air for cooling the condenser 2 and the compressor 1 into the engine room a is provided in the partition wall 35 between the condensing room e and the engine room a.
By the engine room cooling fan F that discharges the cooling air inside,
The cooling air inside the condensing unit e is also sucked and discharged.

As another embodiment, the exhaust air from the engine room cooling fan F is discharged into the exhaust silencer chamber b in which the exhaust muffler M of the engine E is arranged, and is discharged through the exhaust silencer chamber b. It was done.

(E) Embodiments The purpose and structure of the present invention are as described above. Next, the structure of the embodiment shown in the accompanying drawings will be described.

FIG. 1 is a side view of the refrigerating / freezing container of the present invention on the panel 22 side, FIG. 2 is a side view of a part of the side wall of the same, and FIG. 4 is a sectional view of the side wall, and FIG. 5 is a condensing chamber e.
And FIG. 6 is an enlarged view showing a relational arrangement between the engine compartment a and FIG.
The figure is a perspective view showing the discharge state of the cooling air in the container 21.

The overall structure of the refrigerating / freezing container will be described with reference to FIGS. 1 and 2.

A surface of the container 21 on the side of the wife in the front-rear direction is opened, and a panel 22 is fitted instead of the side plate on the side of the wife. A refrigerant cooling unit is attached to the panel 22.

In the refrigerant cooling unit, the part of the cooler unit h composed of the evaporator 10 and the evaporator fan 11 needs to be arranged inside the container 21.
As shown in the drawing, the cooler unit h is arranged on the upper surface of the portion where the refrigerant cooling unit 2 projects inward.

The condenser fan 3 arranged on the outer surface of the panel 22 is connected to the evaporator 10 which constitutes the cooler unit h.
The refrigerant cooled by the condenser 2 and the condenser 2 is sent by piping and blown from the evaporator fan 11,
The air cooled while passing through the evaporator 10 passes through a cooling air duct formed between the protruding portion of the refrigerating / freezing panel 22 and the inside of the container 21 as shown in FIG. Then, the direction is changed by the wind direction plate 23, passes through the bottom cooling wind duct constituted by the corrugated bottom plate 25, and is jetted between the refrigerated frozen products.

The refrigerant cooling unit configured outside the refrigerant cooling unit 2 includes an engine chamber a, an exhaust silencer chamber b, a fuel tank chamber c, a humidifying unit d, a water tank chamber g for the humidifying unit d, and a control panel chamber. It is composed of f and a condensing chamber e.

The present invention particularly relates to cooling the condenser 2 and the compressor 1 arranged in the condensing chamber e, cooling the engine E and the generator D arranged in the engine chamber a, and reducing noise.

The configuration of the cooling device and the noise reduction device for each part of the refrigerant cooling unit of the present invention will be described with reference to FIGS. 3, 4, and 5.

The engine E drives the generator D to supply it to the piezoelectric power compressor 1 to compress the refrigerant and guide it to the condenser 2, and the wind generated by the condenser fan 3 driven by the motor causes the condenser 2 and the compressor to be compressed. 1 is being cooled.

The cooling air generated by the condenser fan 3 is the panel 22.
Taken in from the louver 28 opened in the lid panel 29 of
After cooling the condenser 2 and the compressor 1, a part is discharged from the louver 30.
Since the engine room cooling fan F in the inside is also a louver for sucking the cooling air, most of it passes through the passage port K opened in the partition wall 35 between the condensing chamber e and the engine room a, and the engine is cooled. It is sucked into the chamber e.

The cooling air sucked from the louvers louvers 28 and 30 enters the engine room a and cools them while passing through the outer circumferences of the generator D and the engine E, and an engine room cooling fan configured as a blower fan. It is discharged from the exhaust duct 31 of F.

In this configuration, particularly in the present invention, an exhaust duct
31 is not directly opened to the atmosphere, but is once opened inside the exhaust silencer chamber b in which the exhaust muffler M is arranged, and the exhaust silencer chamber b itself exerts the effect as a silencer. is there.

Therefore, the sound of the condenser fan 3, the sound of the engine room cooling fan F, and the sound of the compressor 1, the generator D, and the engine E all come out from the exhaust duct 31. It can be reduced by the sound deadening effect of b.

The explosion sound in the cylinder of the engine E is caused by the engine exhaust duct 32 and the exhaust muffler M in the exhaust silencer chamber b.
Is exhausted to the atmosphere after being silenced by the exhaust muffler M.

Since the noise emitted from the part where the tip of the exhaust muffler M is open to the atmosphere is the largest, in the configuration shown in FIG. 6, the square pipe arranged as the support column 33 at the corner of the container 21 is used as the second muffler. It is also used as the, and the effect of reducing noise is enhanced.

Exhaust gas may be discharged from the upper end of the support column 33, or conversely, an opening may be provided at the lower end of the support column 33 to discharge the exhaust gas.

The noise reduction effect is higher when the discharge is performed from the lower surface of the support column 33 toward the ground surface.

FIG. 8, FIG. 9, and FIG. 10 show a configuration in which the heat of the exhaust muffler M is used as the heat source of the humidifying unit d.

In the embodiment shown in FIG. 8, the guide pipe 37 from the water tank 36 is directly brought close to the exhaust muffler M, heat is generated to generate steam in the guide pipe 37, and the humidification control valve 38 is opened and closed. It is being sent into the refrigerant cooling unit 2.

In the embodiment shown in FIG. 9, the middle portion of the guide pipe 37 is configured to pass through a steam generation chamber provided around the exhaust muffler M to generate steam. The two humidification control valves 38, 38 are arranged in the above to control the amount of steam.

In FIG. 10, the heat pipe 40 is connected to the exhaust muffler M.
It projects into the inside of the exhaust muffler M to obtain heat from the exhaust muffler M, and the water tank
The heat is dissipated in 36 and steam is generated. The steam in the water tank 36 is configured to be sent to the inside of the panel 22 by a necessary amount by opening and closing the humidification control valve 38.

(F) Effects of the Invention Since the present invention is configured as described above, it has the following effects.

First, in the condensing chamber e, the condenser fan 3
The air that is generated by cooling the condenser 2 and the compressor 1 is sucked into the engine room cooling fan F in the engine room a, which has a higher temperature, again without being discharged from the condensing chamber e into the atmosphere. Since the generator is configured to be used for cooling the generator D and the engine E, the condensing chamber plays a role of canceling noise in the engine room, so that the noise in the engine room can be reduced.

Secondly, since the wind guided into the engine room a and cooling the generator D and the engine E is released into the exhaust silencer room b by the exhaust duct 31 from the engine room cooling fan F, Since the exhaust silencer chamber b functions as a silencer,
The noise in the engine room a can be reduced, and the exhaust muffler M can be cooled by the wind of the engine room cooling fan F.

In FIG. 3, when the temperature inside the condensing chamber e, the temperature inside the engine chamber a, and the temperature inside the exhaust silencer chamber b are compared, they gradually rise, so the louver of the lid panel 29 is increased.
The cooling air sucked by 28 and 30 can be effectively used for cooling the three chambers and then discharged from the exhaust silencer chamber b.
