The specific embodiment
Hereinafter, will describe the utility model in detail.
The utility model provides a kind of refrigerating plant of vehicle refrigerator, as shown in Figure 1, comprises refrigeration system, cooling system and control circuit.Described refrigeration system includes semiconductor cooling device 1, and the cold junction of this refrigeration device 1 is fixed with an aluminium block 2 as conducting piece, can certainly be with the good material of other thermal conduction effects as conducting piece, as copper, aluminium alloy etc.Described cooling system includes duct shield 3, fin 4 and fan 5, and this duct shield 3 is provided with air inlet 31, air channel 32 and air outlet 33 in regular turn.Described fin 4 be arranged in the air channel 32 and with the inwall in air channel 32 suitable distance at interval, smooth and easy to guarantee that air channel 32 internal gas flow.In the present embodiment, the inwall in fin 4 and this air channel 32 is 1 millimeter at interval.In addition, the one side of fin 4 is fixed in the hot junction of refrigeration device 1, and is folded with a foam-rubber cushion 6 between the hot junction of described fin 4 and semiconductor cooling device 1, heat insulation to play, the sealing effect.Described fan 5 is fixed in an end of close air outlet 33 in the duct shield 3.
Described refrigeration system, cooling system are controlled by control circuit.Under the control of control circuit, semiconductor cooling device 1 can be realized two kinds of functions of refrigerating/heating, and by aluminium block 2 cold/the heat of cold junction is passed to the casing of vehicle refrigerator, utilizes fin 4 that the hot/cold in hot junction is passed simultaneously; And utilize the exhausting function of fan 5, and make wind (air-flow) flow from air inlet, air channel, air outlet direction, in time hot/cold is taken out of air channel 32, be unlikely in inside and form eddy current, reached the timely heat radiation (when refrigeration) and (when the heating) effect of dispelling the heat.
Control circuit of the present utility model; as shown in Figure 2; comprise voltage-controlled circuit 71, temperature control circuit 72, refrigerating/heating conversion and delay protection control circuit 73, fan control circuitry 74, display output circuit 75; above-mentioned each circuit is by an EM55100 model integrated chip 70 controls; particular circuit configurations as shown in Figure 3; it is understood by those skilled in the art, is not described further at this.
When refrigerator need freeze, at control circuit connection+12V voltage, voltage is through D1, R1 input three terminal regulator 78L05, stable+5V voltage is provided for EM55100 integrated chip U2 and comparator U3, this moment, 4 pin, 8 pin, 10 pin of integrated chip U2 were high level (4.5～5V), and 5 pin of integrated chip U2,6 pin, 7 pin, 9 pin are low level (0～0.5V); Blue lamp LED1 is bright; Triode Q1, Q3, Q4 conducting, and Q1 ends; Relay K 1 disconnects relay K 2 adhesives simultaneously; Refrigeration device is connected because of forward and is begun refrigeration, and fan rotates and the heat that fin produces extracted out and form circulation, to reach good refrigeration.
When refrigerator need heat, press change-over switch SW1, amber light LED2 extinguishes (refrigeration device disconnect, fan still works on) therebetween after bright 30 seconds, and at this moment, 5 pin of integrated chip U2,8 pin, 9 pin are high level, and 4 pin, 6 pin, 7 pin, 10 pin are low level; Red light LED1 is bright; Triode Q1, Q2, Q4 conducting, and Q3 ends; Relay K 1 adhesive simultaneously, K2 disconnects; Refrigeration device begins to heat because of oppositely connecting, and fan rotates and the cold air that fin produces extracted out and form circulation, to reach good heating effect.
If when refrigerator needs to freeze again, press change-over switch SW1, amber light LED2 extinguished (refrigeration device disconnection therebetween after 30 seconds, fan still works on), blue lamp LED1 is bright simultaneously, and refrigeration device is connected because of forward and is in refrigerating state, and then vehicle refrigerator restarts refrigeration.
When refrigerator need not freeze/heat and only need be incubated the time, came into force back lasting 60 seconds by change-over switch SW2, amber light LED2 and green light LED3 extinguish, at this moment, 4 pin of integrated chip U2～10 pin are low level, LED1～LED3 all extinguishes, and triode Q1～Q4 is and ends, and relay K 1 and K2 are disconnection, fan also stops operating, and refrigeration device access failure and not working, promptly full machine stops, and then vehicle refrigerator begins insulation.
What deserves to be mentioned is, control circuit also has defencive function, and when the c utmost point, the e utmost point of not exporting high level or triode Q1 as integrated chip U2 disconnected, then fan was not worked, the b of triode is high level very, make 5 pin of comparator U3 be lower than 6 pin voltages, and 7 pin are low level, thereby make triode Q4 end, and Q2 and Q3 turn-off, the refrigeration device outage can not damage because of overheated with the protection refrigerator, thereby improve its service life; In addition, because display output circuit is set, the user can understand the interior duty of refrigerator according to the bright/situation of going out of blue, red, Huang and green light; And control circuit also has delay feature, in cold and hot transfer process, certain plenty of time heat radiation is arranged, and can protect refrigerating plant not to be damaged.
In summary, the refrigerating plant of the utility model vehicle refrigerator is owing to adopt semiconductor cooling device, so have that volume is little, noise is little, the life-span is long, an environmental protection, advantage such as energy-conservation; Simultaneously because cooling system adopts special air duct type design, and refrigeration system that matches and control circuit, it is except air inlet and air outlet, other positions of duct shield are all airtight, and fin and duct shield inwall are at interval suitably apart from guaranteeing the smooth and easy of air channel, reaching timely heat radiation (in when refrigeration) and cold scattering (when heating), and can not form eddy current, thereby cooling and warming is effective in inside.
Be understandable that; for the person of ordinary skill of the art; can make other various corresponding changes and distortion according to the technical solution of the utility model and technical conceive, and all these changes and distortion all should belong to the protection domain of the utility model accompanying Claim.
