 Conventionally, a refrigerating vehicle is provided in which a refrigerator is installed in a heat-insulating box mounted on a vehicle body, and a power generator is mounted on the vehicle body to operate the refrigerator to cool the inside of the heat-insulating box. ing.

[0003]

[Problems to be solved by the device]

 In recent years, in the fields of biology and medicine, the transportation of materials that need to be stored at ultra-low temperatures has increased.

However, the above-mentioned conventional refrigerating and refrigerating vehicle cannot be stored in an ultra-low temperature state. Therefore, when transporting an object that needs to be stored in an ultra-low temperature state, a dedicated vehicle is required, which is versatile. In addition to being inferior, it was expensive and not suitable for mass transportation.

[0005]

[Means for Solving the Problems]

 In the refrigerating refrigerator car of the present invention, the refrigerator is installed in the heat insulation box mounted on the vehicle body, and the refrigerating power generator is mounted on the vehicle body, and the refrigerator is operated by the refrigerating power generator. In a refrigerated freezer vehicle that cools the inside of an insulating box, a freezer is detachably mounted inside the insulating box, and the freezing power generator is connected to an appropriate place inside the insulating box to connect to the freezing power generator. It is the one with the possible concentration.

[0006]

[Operation] First, when transporting an item to be stored in an ultra-low temperature state, install a number of freezers corresponding to the amount of the item to be transported in the heat insulation box and cool the inside of the heat insulation box with a refrigerator. By cooling each freezer as well, the items stored in each freezer are stored in an ultra-low temperature state and transported in this state.

Further, when the freezer is not installed in the heat insulating box, the refrigerator is used as a normal refrigerating refrigerator car in which the inside of the heat insulating box is cooled.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

1 and 2 show the structure of a refrigerating refrigerator car according to the present invention.

In the figure, reference numeral 1 denotes a heat insulation box mounted on a vehicle body, and a refrigerator 2 is installed in an upper front part of the heat insulation box 1.

The refrigerator 2 is operated by a refrigerating power generator 3 (see FIG. 4) mounted on the vehicle body to cool the inside of the heat insulation box 1.

A plurality (six in the illustrated example) of freezers 5 are mounted in the heat insulating box 1. The freezer 5 is for cooling an object that needs to be stored in an ultra-low temperature state, and is detachably fixed to the side wall of the heat insulating box 1 by a fixing bracket 6 shown in FIG.

An opening / closing door 51 is provided at the top opening of the freezer 5 so as to be openable and closable, and an object that needs to be stored in an ultra-low temperature state is put in and taken out from the top opening. A caster 52 is provided at the bottom of the freezer 5, and the freezer 5 and the heat insulating box 1 can be loaded and unloaded.

On the other hand, outlets 7 (see FIG. 3) connected to the refrigerating power generator 3 are arranged at appropriate places on the side walls of the heat insulating box 1 corresponding to the freezer 5, respectively. The power plug 53 (see FIG. 3) of the freezer 5 can be connected to the.

An intake duct 11 and an exhaust duct 12 communicating with the outside air are formed on the side wall of the heat insulating box 1, and the intake duct 11 and the exhaust duct 12 are formed corresponding to each of the freezers 5. The intake port 11a and the exhaust port 12a are connected to the intake part 55 and the exhaust part 56 of each freezer 5 when the freezer 5 is fixed by the fixing fitting 6.

FIG. 4 shows an electric system of a refrigerating refrigerator car according to the present invention.

In FIG. 4, reference numeral 81 is an engine of a refrigeration vehicle, 82 is an electromagnetic clutch for power connection / disconnection, 83 is a power generator for traveling, 84 is a regulator, 85 is a battery, 86 is a lamp, traveling control equipment and the like. , SW are operation switches of the refrigerator 2.

Next, a usage mode of the refrigerating refrigerator car configured as described above will be described.

First, when an item to be stored in an ultra-low temperature state is transported, the number of freezers 5 according to the amount of the item to be transported is mounted in the heat insulation box 1 and fixed by the fixing metal fittings 6. The intake part 55 and the exhaust part 56 of the freezer 5 are connected to the intake port 11a and the exhaust port 12a of the intake duct 11 and the exhaust duct 12, and the power plug 53 of the freezer 5 is connected to the socket 7. The unused intake port 11a and exhaust port 12a are closed by blind plates.

Then, the refrigerator 2 cools the inside of the heat-insulating box 1 and also cools each freezer 5, so that the objects housed in each freezer 5 are stored in an ultra-low temperature state and transported in this state. .

Here, each freezer 5 takes in air for cooling the condenser from the outside of the heat insulating box 1 through the intake duct 11, and the hot air passing through the condenser is exhausted to the outside of the heat insulating box 1 through the exhaust duct 12. Therefore, the temperature rise in the heat insulating box 1 due to the exhaust heat of the freezer 5 can be suppressed. In addition, when the number of the freezers 5 installed in the heat insulation box 1 is small and the influence of the exhaust heat of the freezer 5 is small, the freezer 5 is not connected to the intake duct 11 and the exhaust duct 12, and the inside of the heat insulation box 1 is not connected. Air may be taken in and out at.

Further, since the freezer 5 can load and unload the heat-insulating box 1 while containing the cooling object in the freezer 5, it is possible to avoid a rapid temperature change at the time of unloading and loading the heat-insulating box 1. .

Furthermore, since the freezer 5 and the refrigerator 2 are powered from the dedicated refrigeration power generator 3, a constant and stable power can always be obtained, and the performance of the freezer 5 and the refrigerator 2 is sufficiently exhibited. Can be made.

When the freezer 5 is not installed in the heat insulating box 1, the refrigerator 2 can be used as a normal refrigerating refrigeration vehicle in which the heat insulating box 1 is cooled.

[Effect of the device]

 As described above, according to the present invention, it is possible to store in a cryogenic state by installing a freezer inside the heat insulating box, and to prevent normal cooling by a refrigerator by not installing the freezer inside the heat insulating box. In addition to being able to provide an inexpensive and highly versatile refrigerating vehicle, it is also possible to install a required number of freezers according to the amount of cooling material to be transported, enabling mass transportation.
