Figure 1A～Fig. 1 C is respectively the Portable refrigeration of the utility model one embodiment and the schematic appearance of heater (portable cooling and heating apparatus) 10, and Fig. 2 is the Portable refrigeration of the utility model one embodiment and the system block diagram of heater 10.Please merge and consult Figure 1A～Fig. 1 C and Fig. 2, Portable refrigeration and the heater 10 of present embodiment comprise: fuel cell system (fuel cell system) 101, refrigerator (cooler) 103, radiator (heat sink) 105, heat tracing chamber 106(heating chamber) C_heating, and refrigerating chamber 107(cooling chamber) C_cooling.
In present embodiment, fuel cell system 101 can react on fuel (that is methyl alcohol (CH,
3OH)) produce electric power (electrical power) P_FC and heat energy (thermal energy) T_eng.With this understanding, heat tracing chamber 106(C_heating) can react on the heat energy T_eng that fuel cell system 101 produces and a heating/heat insulation function is provided, with the heating/heat preservation zone as for example prepared food.
In addition, refrigerator 103 can be thermoelectric cooling module (thermoel ectric cooler(TEC)), but be not restricted to this, other devices that produce refrigeration through applying electric power are also applicable under condition/situation that design allows.And refrigerator 103 can react on the electric power P_FC that fuel cell system 101 produces and cause refrigerating chamber 107(C_cooling) cold storage function (cooling function) is provided, with the chill space as drinks such as for example red wines.Moreover radiator 105 mainly can be to refrigerator 103 operation of dispelling the heat.
Composition framework with fuel cell system 101, fuel cell system 101 can comprise: control module (control module) 101a, fuel cell module (fuel cell module) 101b, power supply changeover device (power converter) 101c, and rechargeable battery module (rechargeable battery module) 101d.
Power supply changeover device 101c is coupled between fuel cell module 101a and the refrigerator 103, and is controlled by control module 101a.In present embodiment, power supply changeover device 101c can be DC-to-dc converter (DC-DC converter), for example: and step-down/up type (boost-buck) DC-to-dc converter, but be not restricted to this.Power supply changeover device 101c mainly can change (that is, the DC-to-dc conversion) to the first electric power P_1 that produces from fuel cell module 101b, gives refrigerator 103 with output power P_FC.
Power supply changeover device 101c can change (that is, the DC-to-dc conversion) in addition to the second electric power P_2 that produces from rechargeable battery module 101d, gives refrigerator 103 with output power P_FC.That is to say that output power P_FC can comprise simultaneously the second electric power P_2 (being P_FC=P_1+P_2) that the first electric power P_1 that produces from fuel cell module 101b and rechargeable battery module 101d produce.In addition, rechargeable battery module 101d can be when fuel cell module 101b initial launch, provide startup electric power P_ini to give its interior periphery element (balance of plant to fuel cell module 101b, BOP) normal operation, treat that the first electric power P_1 that fuel cell module 101b produces is when starting electric power P_ini, P_FC 〉=0 then, represent that namely fuel cell module 101b normally moves, rechargeable battery module 101d will stop to provide startup electric power P_ini to fuel cell module 101b this moment.
In present embodiment, control module 101a can also be coupled to the output of power supply changeover device 101c, whether reaches rated electrical (rated power) P_TEC of refrigerator 103 to judge electric power P_FC that power supply changeover device 101c is exported.
When control module 101a judges electric power P_FC that power supply changeover device 101c exports and do not reach the rated electrical P_TEC of refrigerator 103 (P_FC＜P_TEC), it may be the first electric power P_1 deficiency that fuel cell module 101b produces, then control module 101a can control rechargeable battery module 101d further and changes to power supply changeover device 101c so that the second electric power P_2 to be provided, and the electric power P_FC=P_1+P_2 that reaches output meets the rated electrical P_TEC of refrigerator 103 at least.Thus, power supply changeover device 101c can be simultaneously change (being the DC-to-dc conversion) to first and second electric power P_1, the P_2 that comes from fuel cell module 101b and rechargeable battery module 101d respectively, and it is P_FC 〉=P_TEC) that the electric power P_FC that meets the rated electrical P_TEC of refrigerator 103 with output at least gives refrigerator 103(.
On the other hand, when control module 101a judges electric power P_FC that power supply changeover device 101c exports and reached the rated electrical P_TEC of refrigerator 103 at least (P_FC 〉=P_TEC), then control module 101a can judge further that the rated electrical P_TEC(whether electric power P_FC that the first electric power P_1 that fuel cell module 101b exports exports equals or exceeds refrigerator 103 is P_FC=P_TEC behind power supply changeover device 101c, or P_FC＞P_TEC).
When control module 101a judges electric power P_FC that the first electric power P_1 that fuel cell module 101b exports exports and surpasses the rated electrical P_TEC of refrigerator 103 behind power supply changeover device 101c (P_FC＞P_TEC), then control module 101a can control the electric power P_FC that power supply changeover device 101c output just meets the rated electrical P_TEC of refrigerator 103 further and gives refrigerator 103(namely, P_FC=P_TEC), and control power supply changeover device 101c is P_remain=P_FC-P_TEC with remaining additional power P_remain() provide to rechargeable battery module 101d, so that rechargeable battery module 101d is charged.Apparently, if the electric power P_FC that the first electric power P_1 that fuel cell module 101b exports exports behind power supply changeover device 101c surpasses the words of the rated electrical P_TEC of refrigerator 103, then power supply changeover device 101c not only can export the required electric power P_FC of refrigerator 103, but also can provide additional power P_remain so that rechargeable battery module 101d is charged.
Yet, what deserves to be mentioned is at this, if the electric weight of rechargeable battery module 101d is lower than lower limit (as 30%SOC, but be not restricted to this), control module 101a can be with output (output stage) forbidden energy (disable) of power supply changeover device 101c, force refrigerator 103 out of service, thereby make the rechargeable battery module 101d of fuel cell module 101b of fuel cell system 101 charge.
In addition, when control module 101a judges electric power P_FC that the first electric power P_1 that fuel cell module 101b exports exports and approximately or just equals the rated electrical P_TEC of refrigerator 103 behind power supply changeover device 101c (, P_FC ≈ P_TEC, or P_FC=P_TEC), then control module 101a can control further electric power P_FC that the first electric power P_1 that power supply changeover device 101c exports fuel cell module 101b exports behind power supply changeover device 101c all/provide to refrigerator 103 totally.Meanwhile, rechargeable battery module 101d can not provide the second electric power P_2 to power supply changeover device 101c, and power supply changeover device 101c can not provide additional power P_remain so that rechargeable battery module 101d is charged yet.
What hence one can see that is, Portable refrigeration and heater 10 its inside include the fuel cell system 101 as DMFC (DMFC) system, so it can be under the enough condition of methanol fuel supply and keeps long-time continuous service, thereby possess the characteristic that autonomous supply of electric power is arranged, the portable system that can be extended to outdoor no commercial power supply is by this smoothly used.
On the other hand, can produce electric power P_FC and heat energy T_eng based on the fuel cell system 101 as DMFC (DMFC) system when the operation.Therefore, the heat tracing chamber 106(C_heating of Portable refrigeration and heater 10) can react on the heat energy T_eng that fuel cell system 101 produces and an insulation/heating function is provided; And the refrigerator 103 of Portable refrigeration and heater 10 can react on the electric power P_FC that fuel cell system 101 produces and cause refrigerating chamber 107(C_cooling) cold storage function is provided, thus make Portable refrigeration and heater 10 that the effect of refrigeration and heating can be provided simultaneously.
Moreover, in practical application, the generated output of supposing fuel cell module 101b is under the situation of 20W, be in generator operation after about 20 minutes in Portable refrigeration and heater 10, then the heat energy T_eng that provides of fuel cell module 101b can make fuel cell module 101b be promoted to 75 ° of C by 25 ° of C of room temperature, and maintains 65 ° of C～75 ° C in follow-up stable run duration.Thus, the heat tracing chamber 106(C_heating of Portable refrigeration and heater 10) just can provide an insulation/heating function.
In addition, if under identical assumed condition, be in generator operation after about 15 minutes in Portable refrigeration and heater 10, then refrigerator 103 can react on the electric power P_FC that power supply changeover device 101c exports the rated electrical P_TEC that meets refrigerator 103, and cause refrigerating chamber 107(C_cooling) temperature be brought down below by 25 ° of C of room temperature or equal 10 ° of C, and under the operation of homeostasis, remain on 9 ° of C.Thus, the refrigerating chamber 107(C_cooling of Portable refrigeration and heater 10) just can provide a cold storage function.
