As shown in Figure 2, cooling system 1 roughly is made of cryogenic media generation device 2 and casing 10.In the inside of cryogenic media generation device 2, the cold-producing medium that has passed through compressor 20, condenser 21 is through expansion valve 22 and heat absorption in vaporizer 23, and the cooling medium at the internal circulation of medium pipeline 3 is cooled off.As cooling medium, can adopt dry air, salt solution, cold water etc., but, also have the cold-producing medium (for example ammonia, carbon dioxide, air) from above-mentioned cryogenic media generation device 2 is reduced pressure, with the situation of its direct feeding medium pipeline 3.
Above the chamber 14 that is cooled of the inside of inner wall 12, for example be provided with 4 fans 15 as an example of air circulation device.Also have, on the ceiling face of inner wall 12, be provided with the fin 16 of the plate-shaped member that a plurality of conducts erect.Fin 16 sets for the twocouese that is flowing in of the air due to the fan 15, improves from the heat transfer of inner wall 12 to air by increasing film-cooled heat.
Also have, on outer wall 11 and inner wall 12, formed the gateway 17 with external communications at two ends, have the conveyor assembly 30 that connects from the outside in the chamber 14 that is cooled and transport the product of being cooled.Driven roller 32 and driven voller 33 rotate belt body 31, thereby conveyor assembly 30 is transplanted on the product 34 that are cooled in the chamber 14 that is cooled continuously.
Herein, fan 15 is located at the substantial middle portion of the chamber 14 that is cooled, that is, and and from the position farthest, gateway of conveyor assembly 30.Prevent thus in the outdoor air that contained moisture becomes frost and attached on the fan 15, lengthens working hours.Also have, 4 fan 15 per 2 back-to-back configurations are configured to supply gas to gateway 17 along the ceiling of inner wall 12.
Have again, in the present embodiment, as shown in Figure 2, above conveyor assembly 30, have the interval body 40 of a plurality of hollows.Interval body 40 is erected at the direction with the driving direction quadrature of belt body 31, and opens the interval of regulation and arrange at the driving direction sky of belt body 31.Gap by the interval body 40 of this adjacency has formed slit 41, and the air of circulation blows out from this slit 41 in the chamber 14 that is cooled, and blows pair to being cooled product 34.In addition, interval body 40 is installed removably in order to clean and to reorganize and outfit.
And as shown in Figure 1, interval body 40 is directly installed on the side of inner wall 12, and its inside is hollow, is communicated with medium circulation road 13.Therefore circulate to cryogenic media generation device 2 from medium pipeline 3 through medium circulation road 13 once more in the inside of the cooling medium of having supplied with from medium pipeline 3 through medium circulation road 13 and by interval body 40.

Therefore, no matter the wind direction of fan 15 how, can both be discharged the cooling air from all slits 41.
The cooling air of above conveyor assembly 30, discharging, slit 41 just below become high wind, form the high wind district, interval body 40 just below become weak wind, form weak wind district.The product that are cooled 34 that transported by conveyor assembly 30 alternately pass through these high wind districts and weak wind district, thereby in the high wind district, surface element is by cooling off from the heat transmission of cooling air, in weak wind district, the cold and hot of surface element arrives core by the heat conduction, thereby the product that are cooled are frozen under the state that the temperature difference of surface element and core diminishes, can be owing to not freezing the irregular quality badness that causes the product of being cooled, and the product surface of being cooled crackle can not occur.
At this moment, in the slit of passing through before cooling air contact is cooled product 34 41, interval body 40 is initiatively cooled off by the cooling medium of the inside by hollow, thereby this is cold and hotly directly passed to the product of being cooled 34.
Therefore, even also can cool off the product of being cooled 34 effectively in double-walled cooling system cooling, that not talkative cooling effectiveness is high indirectly.
In addition, the wall that the cooling effect in the medium circulation road 13 is big has strengthened the width on medium circulation road 13, only flows through on a small quantity or do not flow through fully heat transfer medium on the bed surface.Interval body 40 cooling effects are big, thereby strengthened the stream of heat transfer medium, and this is preferred.
Also have, same with the fin 16 that is provided with on the ceiling of inner wall 12, also be provided with fin on the interval body 40, this is preferred (not shown).So just can transmit cold and hot more effectively.
Also have, preferably, the shape in slit 41 (being the shape of the interval body 40,40 of adjacency) be with the chamber 14 that is cooled in the identical direction of wind direction of cooling air of circulation.So just can reduce air drag, further improve cooling effectiveness.Have, the direction in slit 41 nearby tilts to the direction of the air-flow due to the fan 15 in the gateway 17 of conveyor assembly 30 again, so that side directed in installing this air-flow, this is preferred.Therefore, as shown in Figure 1, the side of gateway 17 interval body 40a nearby is different with the interval body 40 that is configured in central portion, constitutes with the shape that forms the slit that tilts.The cold air in the chamber 14 of so just preventing to be cooled 17 flows out to the outside from the gateway, works as so-called gas curtain.
As described above, in the chamber 14 that is cooled, there is not cooler, cool off from the whole wall on medium circulation road 13, thereby the heat exchange amount of unit are diminishes, so can make the generation of frost fall extremely lowly.Particularly can avoid because of making in as the medium circulation road 13 in airtight space, circulating in the unit of cryogenic media generation device 2 problem of frost of cooling medium.
Also have, compare with the occasion of direct cooling, can make the air-flow of the cooling air of circulation in the chamber 14 that is cooled become very weak, thereby can reduce the drying of the product that are cooled 34, and the gas of the product of being cooled 34 is dispersed, can also prevent inner and product 34 pollution each other that is cooled of locking apparatus.
Also have, constitute, the interval body 40 that is configured in the upstream side of the product that are cooled 34 in the circulation of cooling off air is a hollow, and cooling medium is cooled off in inner loop, thereby can before contact is cooled product 34, cool off air, can greatly improve cooling effectiveness.
