Embodiment
Extremely shown in Figure 6 like Fig. 1 is a kind of preferable practical implementation example of the utility model; A kind of cold storage constant temperature experimental box; Comprise insulation can 10, cold-storage device 20 and refrigerating plant 30, wherein, this insulation can 10 has constant temperature enclosure 11, cold storage chamber 12 and lays chamber 13; Offer air admission hole 111 and venthole 112 between this constant temperature enclosure 11 and this cold storage chamber 12; Make the cold in this cold storage chamber 12 can see through air admission hole 111 entering in this constant temperature enclosure 11, from venthole 112, get back in this cold storage chamber 12 again, cold is circulated between this constant temperature enclosure 11 and this cold storage chamber 12.
This cold-storage device 20 is placed in this cold storage chamber 12; And being placed on this, lays in the chamber 13 by this refrigerating plant 30; This refrigerating plant 30 is connected with this cold-storage device 20; After the cold that these refrigerating plant 30 work are produced at first passed through these cold-storage device 20 cold-storages, the cold that this constant temperature enclosure 11 relies on this cold-storage device 20 to store came holding temperature.
What deserves to be mentioned is that the schematic diagram of the refrigerating plant 30 shown in Fig. 1 is illustrated in insulation can 10 outsides and its objective is the position relation that shows between each part in the refrigerating plant 30 for clear, and in fact cold-storage device 30 is placed on and lays in the chamber 13.
Be provided with airduct 113 in this constant temperature enclosure 11; This airduct 113 offers some air outlets; In this cold storage chamber 12 of these air admission hole 111 downsides adjustable speed recycle blower 121 is installed; This adjustable speed recycle blower 121 links together with this airduct 113; Make this adjustable speed recycle blower 121 from cold storage chamber 12, extract cold and flow in this constant temperature enclosure 11 through this airduct 113, cold enters in this constant temperature enclosure 11 through the air outlet of this airduct 113, and then cold is circulated back to this cold storage chamber 12 from this venthole 112.
This cold-storage device 20 is arranged between this air admission hole 111 and the venthole 112; The cold that this adjustable speed recycle blower 121 is extracted flows out from this cold-storage device 20; After this refrigerating plant 30 quit work, the cold that this adjustable speed recycle blower 121 extracts these cold-storage device 20 storages was kept the temperature of this constant temperature enclosure 11.
As shown in Figure 2; This cold-storage device 20 comprises cold storage box 21 and some cold-storages unit 22; Wherein, some these cold-storage unit 22 are fixed in this cold storage box 21, and some these cold-storage unit 22 connect as one (shown in Figure 3) through connecting pipe 23; And not being parallel to each other between per two adjacent cold-storage unit 22, so that the surface of cold-storage unit 22 ponding not.
As shown in Figure 4; The right ends of this cold storage box 21 all offers the through hole 211 (through hole 211 of only representing cold storage box 21 1 ends among Fig. 4; And do not represent the through hole of the other end obviously to be enough to let the through hole that those skilled in the art will know that the other end how offer the therefore through hole 211 through the diagram expression cold storage box other end no longer through Fig. 4); So that flowing to the cold of cold storage chamber 12, constant temperature enclosure 11 can enter into this cold storage box 21, so that cold circulates between this constant temperature enclosure 11 and this cold storage chamber 12.
As shown in Figure 1; This refrigerating plant 30 comprises by the compressor 31 of driven by motor and condenser 32; This compressor 31 is connected with cold-storage device 20 through return-air tube 311, and this condenser 32 links together with this compressor 31, and the arranged outside of this condenser 32 has blower fan 33; This condenser 32 and a device for drying and filtering 321 connect, and this device for drying and filtering 321 then is connected with this cold-storage device 20.
Particularly, this compressor 31 is to link together through the evaporator 221 in refrigeration piping and this cold-storage device 20, and 321 evaporators 221 through kapillary and this cold-storage device 20 of this device for drying and filtering link together equally.
Particularly, this compressor 32 is to be connected with the inlet 223 of the evaporator that is in bottom 221, and this device for drying and filtering 321 then is connected with the inlet 223 of the evaporator that is in the first floor 221.
The position of this venthole 112 of this constant temperature enclosure 11 is provided with temperature sensor 114, on this cold-storage device 20 temperature sensor 114 is installed also, and the control circuit that starts refrigerating plant 30 work through temperature sensor is a known technology, repeats no more at this.
What deserves to be mentioned is that this insulation can 10 is provided with appliance controling plate 14, this appliance controling plate 14 is electrically connected with electrical equipment such as this adjustable speed recycle blower 121, compressor 31, blower fan 33, temperature sensors 114 through lead respectively.
Normally closed air door 115 is installed in the hole of this venthole 112, and normally closed air door 115 is opened under the effect of leeway automatically during blower fan 33 operations, and when blower fan 33 quit work, this normally closed air door 115 leaned on gravity to keep shut automatically.The wind speed of blower fan 33 carries out speed governing by temperature sensor 114; Such as, setting the temperature that need in the constant temperature enclosure 11 to keep is 20 ± 1 ℃, and when the temperature of constant temperature enclosure in 19 ℃ to 21 ℃ scopes the time; The rotating speed of blower fan 33 increases with the increase of temperature, otherwise reduces.
And worth explanation is that motor starts, stops under the control under the temperature sensor 114.Temperature in the constant temperature enclosure 11 extracts cold by the adjustable speed fan blower from cold storage chamber and keeps, and cold is circulated to cold storage chamber through behind the constant temperature enclosure, so repeatedly circulation.
After this refrigerating plant 30 quits work; When leaning on cold-storage source (cold-storage device) to keep the temperature of constant temperature enclosure; This adjustable speed recycle blower work, the cold that low-temperature receiver relies on hold-over plate 222 to store is kept the temperature of constant temperature enclosure, and the temperature of constant temperature enclosure is controlled between 20 ± 1 ℃; This fan starting when the temperature of constant temperature enclosure is 21 ℃, blower fan is out of service in the time of 19 ℃.
Embodiment of the utility model and accompanying drawing are just in order to show the design concept of the utility model, and the protection domain of the utility model should not be confined to this embodiment.
Can find out that through top narration the purpose of design of the utility model can effectively implement.The part of embodiment has been showed the purpose of the utility model and has been implemented function and structural themes, and comprised other the replacement that is equal to.
Therefore, the right of the utility model constitutes the equivalence that comprises other to be implemented, and the concrete right scope is with reference to claim.
