Specific embodiment
The utility model is described in further detail With reference to embodiment.
Shown in referring to FIG. 1, FIG. 2 and FIG. 3, cold source box box body 2, cold source box box body 2 are installed in the top of reefer body inner wall Cold source box box cover 9 is installed at top, and cold source box box cover is arranged gas vent, is equipped with aluminium sheet 7 above lower surface in reefer body, cold It hides and fills thermal insulation material polyurethane 3 between the inside and outside wall of box body, filling thermal insulation material is poly- between the inside and outside wall of cold source box box body Pipe-line system is arranged between the inside and outside wall of reefer body for urethane 3, and the pipe-line system is by one 6-1 of collector, two 6-2 of collector, collection Three 6-3 of pipe and four 6-4 of collector composition, collector four are " L " type, and collector four is mounted on inside and outside along the side wall of cold source box box body and bottom surface Between wall, collector three is U-typed, and collector three is mounted between inside and outside wall along the left side wall of reefer body, bottom surface and right side wall, One end connection with the lower end of collector four and collector two, the both ends of collector three are another with collector two respectively respectively at the both ends of collector one The upper end connection of one end and collector four is provided with intake valve 10-1 and air outlet valve 10-2 on collector three.
What dotted line indicated is the pipe-line system of refrigerated storage fresh keeping box in Fig. 1, for convenience of observing, by pipe-line system in Fig. 3 It individually indicates, to make device figure convenient for observing, intake valve 10-1 and air outlet valve 10-2 is omitted in Fig. 1, by its table in Fig. 3 It shows and.Because of refrigerating box small volume, if copper pipe 4 and collector 6 are placed on welded again in case if having inconvenience, then Before assembling, first pipe-line system is welded, the size of pipe-line system determines according to actual needs.After pipe-line system completion, The filling for carrying out refrigerant, intake valve 10-1 is opened, is inflated, after filling appropriate time, exhaust valve 10-2 is opened, centainly After time, exhaust valve 10-2 is closed, after injecting suitable refrigerant in pipe-line system, intake valve 10-1 is closed, is filled Refrigerant is infused to complete.This process is always maintained at inflated condition, it is therefore an objective to exclude the air in pipe-line system clean.It is worth noting , the number of the copper pipe 4 of pipe-line system needs the volume according to refrigerated storage fresh keeping box, and inner wall area is designed, and is not 4 pipelines or 7 pipelines shown in Fig. 3, in addition, three 6-3 of collector, to four 6-4 pipeline section of collector, the arrangement of pipeline needs Certain gradient, specially four 6-4 of collector are slightly below three 6-3 of collector.Reefer body 1, refrigerating box case lid 5, cold source box box body 2 and cold source box box cover 9, matched design is carried out according to the size of pipe-line system, cabinet and box body intermediate course fill thermal insulation material Polyurethane 3, the inside and outside wall of cabinet are all made of hard polyurethane material, and the inside and outside wall of cold source box is all made of hard polyurethane material, Cold source box is fixed on refrigeration chamber interior wall, and specific relative position is as shown in Figure 6.When carrying out the manufacture of cold source box, cold source box is close That two faces of refrigeration chamber interior wall need to reserve necessary space when position and the assembling of pipe-line system.Cold source box box body is such as Shown in Fig. 4, the top of cold source box box cover need to manufacture gas vent 8, as shown in Figure 5.Referring to shown in Fig. 8, lower surface in refrigerating box case Aluminium sheet 7 is equipped with above pipeline, when body structure and pipe-line system all manufactures and finished, carries out the assembling of the two, after being completed, Pipe-line system is secured firmly to refrigeration chamber interior wall and cold source box inner wall, with foamed glue filling due to assembling existing for reveal cooling capacity Gap or hole.Referring to shown in Fig. 9, Figure 10, annular groove one, cold source box box cover is arranged in the outer peripheral surface on cold source box box body top Annular groove two is arranged in the inner peripheral surface of bottom end, and cold source box box body is chimeric with cold source box box cover.Referring to shown in Fig. 7, Fig. 8, refrigerating box Annular groove three is arranged in the outer peripheral surface on cabinet top, and annular groove four, refrigerating box case is arranged in the inner peripheral surface of refrigerating box case lid bottom end Body is chimeric with refrigerating box case lid.Door seal magnetic stripe is installed in the cabinet of refrigerating box and the junction (outside case) of case lid.
The lesser refrigerant of appropriate pressure is injected in pipe-line system, and the thing for needing cold storing and fresh-keeping is placed on aluminium sheet 7 Face is put into suitable dry ice in cold source box and covers cold source box cover 9 and refrigeration case lid 5, dioxy made of dry ice sublimation Change carbon gas and cold source box is discharged by cold source box gas vent 8, avoids the generation due to carbon dioxide that pressure in cold source box is caused to become Greatly.Since dry ice sublimation absorbs heat, the refrigerant gas exothermic condensation in the pipeline near cold source box is at refrigerant liquid, liquid Body is converged in one 6-1 of collector due to the reason of gravity and is then flowed into two 6-2 of collector, and liquid is at two 6-2 of collector because gravity is made With flowing downward, in this process, two 6-2 of collector pipeline below and the pipeline for being laid in bottom are equivalent in refrigeration system Evaporator, the refrigerant liquid in pipe absorbs the heat of vaporization in cabinet and forms refrigerant gas, and gas is due to autologous density Reason is risen in pipeline at three 6-3 of collector, because refrigerant liquid endlessly generates at one 6-1 of collector, therefore is existed Pressure difference flows away the refrigerant gas at three 6-3 of collector to four 6-4 of collector, in four 6-4 of collector between one 6-1 of collector This section of pipeline, because dry ice sublimation absorbs heat in cold source box, the refrigerant gas exothermic condensation in pipeline is at refrigerant liquid, because of weight Power effect flow to two 6-2 of collector, so far repeat above-mentioned circulation so that refrigerant by the cooling capacity that dry ice sublimation generates uniformly send to Each position of refrigerated storage fresh keeping box guarantees refrigeration quality.
When needing chilled goods in refrigerating box, it is suitable to be determined according to the length of cold preservation time and required cooling capacity Dry ice shape and dry ice quality, for example, being put into the relatively small sphere of surface area of appropriate quality when cold preservation time is longer Dry ice, to ensure that dry ice sublimation speed is slower than the dry ice of the other shapes of homogenous quantities.
Although the utility model is described above in conjunction with figure, the utility model is not limited to above-mentioned tool Body embodiment, the above mentioned embodiment is only schematical, rather than restrictive, the ordinary skill people of this field Member, in the case where not departing from the utility model aims, can also make many variations under the enlightenment of the utility model, these It belongs within the protection of the utility model.
