Description
Technical field
The present invention relates to a kind of SCM Based solar generator refrigeration mobile icebox.
Background technology
The mechanism of thermoelectric cooling is different from steam compression type refrigeration, absorption refrigeration completely.It is the refrigerating method based on difference of temperature.
Interconnect with two kinds of different wires, form a closed circuit, two tie points are placed on two different places of temperature respectively, an electrical potential difference will be produced between two tie points---contact electromotive force.Just there is electric current to pass through in closed circuit simultaneously.
Conversely, the closed circuit that two kinds of different metal wires are interconnected to form is passed to direct current, the tie point of two different temperatures can be produced.
As long as pass to direct current, will be one of them tie point heating, another tie point turns cold.Here it is peltier effect, also known as difference of temperature.Producing cold junction is exactly the refrigeration that we need.
Within 1834, French physician Peltier respectively connects a bismuth silk at two of copper wire, is being received respectively on the both positive and negative polarity of dc source by two bismuth silks, and after energising, find a joint heating, another joint turns cold; This illustrate the electric loop of two kinds of different materials composition have direct current by time, two joints there occurs suction exothermic phenomenon respectively.The foundation of thermoelectric cooling that Here it is.
Semi-conducting material has higher thermoelectrical potential and can successfully be used for making mini thermoelectric heat refrigerator.With copper coin and copper conductor, N-type semiconductor and P-type semiconductor are connected into a loop, copper coin and copper conductor only play conduction.Now, a contact heating, another contact turns cold; If the sense of current is reverse, so cold and hot effect reciprocity at node place.
The refrigeratory capacity of TEC is general very little, so unsuitable extensive and large refrigerating capacity uses.But because its flexibility is strong, simple and convenient cold and hot switching is easy, what be suitable for very much minisize refrigeration field or have a particular/special requirement uses awkward silence at a meeting institute.
The theoretical foundation of thermoelectric cooling is the pyroelectric effect of solid, when existing without external magnetic field, it comprises five effects: Fourier (Fourier) effect, joule (Joule) effect, Seebeck (Seebeck) effect, Peltier (Peltire) effect and Thomson (Thomson) effect.

2, need pulse width modulating technology control system, power electric component causes system price high, and easily damages.
3, alternating current 220V civil power is that fixed form is powered, and the scope of application is restricted, and cannot apply in mobile occasion.
Have in addition and directly provide galvanic thermoelectric cooling refrigerator by battery, the shortcoming battery power of this mode is limited, can not last much longer, and the battery has run down just can not continue to have freezed.

There is no moving component: TEC only uses electric energy when work, and do not have the parts of any motion, so, they do not need maintaining substantially.
Volume and weight is very little: the volume and weight of a thermoelectric refrigerating system will be far smaller than corresponding mechanical refrigeration system.In addition, for various application requirement strictly, that have various standard or special size and layout type available.
Below environment temperature can be cooled to: traditional radiator needs temperature to be elevated to more than environment temperature and just can use, and has with it ability object temperature being reduced to below environment temperature unlike TEC.
Same device can meet the requirement heating up and lower the temperature: the direction of the DC current that TEC can be loaded by adjustment, adjustment is freezed or heating mode.Apply this feature and just need not add in addition independently heating or refrigerating function element in given system.
Accurate temperature controls: because TEC has a closed circuit temperature control cycles, it can within the scope of 0.1 DEG C accurately control temperature.
High reliability: owing to being all solid-state base structure, TEC has very high reliability.Although relevant with application conditions in a way, the life-span of typical TEC generally can reach 200, more than 000 hour.
Electronics is quiet: different from traditional mechanical refrigeration device, and TEC can not produce any electronic interferences signal in the course of the work substantially, and it can be connected with the electronic inductor of sensitivity, can't disturb its work.In addition, it also can not produce any noise in running.
Can in arbitrarily angled lower work: TEC can work under arbitrarily angled and zero-g state again.So, apply widely in space flight apparatus.
Energy resource supply simply and easily: TEC directly can use dc source, and the voltage and current of loading power can in very large range change.Under a number of conditions, pulse width modulation can also be used.
Point refrigeration: application TEC, can accomplish to freeze to independent unit or very little region, the energy waste that may cause when therefore can avoid cooling whole packaging or shell.
Generating: use its " inverse process " by loading the temperature difference on TEC, can be become a little DC generation device.
Environmental friendliness: traditional mechanical refrigeration system operationally inevitably needs to use freon or other chemical substances, and these materials are very harmful to environment.And thermo-electric device can not relate to these chemical substances, and also can not produce any pernicious gas in the course of work.
A kind of perspective view of embodiment is invented see Fig. 3.
Related data that can be concrete is:
Cooling piece size 40 × 40 × 5mm, heavily about 20g.
Cold and hot surface maximum temperature difference can reach more than 60 DEG C.
Cold junction face and hot junction interplanar distance are about 4mm.
Although this patent is explained with reference to preferred embodiment and accompanying drawing, but above-mentioned explanation should be considered as illustrative and non-limiting, and the change that person's spirit according to the present invention of being familiar with technique is made and amendment, all should belong to the protection domain of this patent.
