Abstract
The invention discloses a technique of refrigeration and power generation by using splitting type of thermocouple. The PN end and the NP end of thermocouple are split in to two parts that can make relatiev move with eath other freely. There are conductors to connecta pair of P type of semiconductor thermoelectric materials and a pair of N type of semiconductor thermoelectric materials respectively. Since two ends of the thermocouple is freely split, thus it avoids negative influence brought by heat exchange between two ends, meanwhile it makes installation of thermocouple more easily.
Description
The present invention relates to a kind of split type thermocouple refrigeration and generation technology, belong to the semiconductor electronic application.
At present, the core devices thermoelectricity that utilizes the thermoelectric effect refrigeration and generate electricity is thermopile occasionally, on manufacturing process, generally adopt at the two ends of a pair of thermoelectric material (P-type material and n type material) and be connected with metallic conductor (normally copper), and the mode that inserts power supply therein between an end metallic conductor is made, because thermoelectric material costs an arm and a leg and its mechanical strength is lower, that does on length usually is all very short.In recent years, the electronic cooling technology is a dark horse, the trend that alternative mechanical compression refrigeration is arranged greatly, reason is that electronic cooling has very big advantage, it does not use cold-producing medium, and is free from environmental pollution, and noiselessness, nothing are worn and torn, volume is little, in light weight, reliable, easy to maintenance, can only cool off a special element or specific area.For the application of thermoelectric effect generating, its advantage is the middle conversion process that has not had mechanical energy of the generation from heat energy to the electric energy, has noiselessness equally and does not have wearing and tearing, reliable easy to maintenance and little, the lightweight characteristics of volume.But, just be used for special part refrigeration with regard to this technology in electronic cooling aspect, be not used to powerful household electrical appliance.Its reason is: there is heat conduction in (1) between hot junction and cold junction; (2) heat of pyrometer fire-end can not scatter and disappear timely and effectively.
Because it is all very short that thermoelectric material is done on length, so heat-conduction effect is very remarkable, this part conduction heat energy needs extra electric energy acting to transport it into pyrometer fire-end, and this part electric energy finally gathers in the hot junction with the form of heat energy.Hot junction and cold junction directly are linked to be integral body by thermoelectric material simultaneously, owing to be subjected to the restriction in integral installation space, cause hot end heat sink to be difficult to coupling and installation.The sharp increase result of this heat energy causes refrigeration thermocouple components and parts refrigeration usefulness to fall sharply, and can't realize the mechanical compression refrigeration effect of present household refrigerating appliance.
For thermocouple generator, its generating prerequisite is must hold at PN between (electric current is from P to N) and the NP end (electric current is from N to P) to set up the temperature difference.But because heat conducting existence causes the two ends temperature difference to be eliminated in a short period of time, so low power thermocouple generator also is difficult for realizing in real world applications.
The purpose of this invention is to provide a kind of thermocouple refrigeration and generation technology that does not have heat conduction negative effect influence, cold and hot two ends are effectively separated, make thermoelectric cooling and the generation technology practicability that more becomes.
To achieve these goals, the present invention changes into present thermocouple structure split type from integral type.So-called split type thermocouple is exactly to insert lead in the middle of the semi-conductor thermoelectric material that directly connects cold and hot two ends, enlarges the distance in cold junction and hot junction.In temperature difference circuit, introduce the characteristic that the third material (brace and lead) can not change circuit according to present experiment showed,, so also can not change the refrigeration and the power generation characteristics of former thermocouple at the middle lead-in conductor of thermoelectric material of the same race.
The back is effectively separated by lead in the cold and hot two ends of thermocouple:
The one, eliminates the negative effect that the heat conduction of cold and hot two ends brings for thermocouple refrigeration and power generation performance fully.
The 2nd, makes the installation at cold and hot two ends freer, can realize remote installation.
The split type thermocouple of making in this way is when cold, according to thermocouple refrigeration refrigeratory capacity formula: Q
0=Q
p-Q
Hc=α
AbT
cI-1/2I
2The hot K Δ of R-K Δ T conduction wherein T part will be eliminated, and thermocouple refrigeration refrigeratory capacity formula is become:
Q
0=Q
p-Q
Hc=α
AbT
cI-1/2I
2So R is few for the split type thermocouple consumes power of identical refrigeratory capacity, the quantity of heat production in the hot junction also just lacks, thereby thermocouple refrigeration effect and performance are improved.On the other hand, cold junction and hot junction no longer are an integral body, can realize freely assembling at a distance, make the easier coupling of heat abstractor in hot junction.This split type thermocouple refrigeration technology makes high-power family expenses refrigerator such as electronic cooling air-conditioning, and electronic cooling refrigerator etc. becomes possibility.When the thermocouple made from this technology was used to generate electricity, it is far that the two ends of thermocouple can be put, and do not have heat conducting negative effect again, makes its operate as normal under the constant temperature difference.This split type thermocouple generation technology makes the open-air bonfire direct generation of electricity and the underground heat direct generation of electricity etc. become possibility.
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
The split type thermocouple structure signal of Fig. 1.
Fig. 2 is split type thermocouple series connection thermoelectric pile schematic diagram.
Fig. 3 is a split type thermocouple thermoelectric pile schematic diagram in parallel.
As the split type thermocouple structure schematic diagram of Fig. 1, by metal connecting sheet 1, P type semiconductor thermoelectric material 2, N type semiconductor thermoelectric material 3, lead 4 and DC power supply 5 constitute.P type semiconductor thermoelectric material 2 and N type semiconductor thermoelectric material 3 connect with metal connecting sheet 1 respectively, constitute two ends of split type thermocouple.In the middle of P type semiconductor thermoelectric material 2 and N type semiconductor thermoelectric material 3, insert lead 4 respectively, and in the middle of one of two leads, introduce DC power supply 5.During refrigeration, DC power supply 5 is outwards powered, PN end and difference heat release of NP end and refrigeration.During generating, place the PN end low temperature environment NP end to place hot environment, in split type thermocouple circuit, form thermoelectromotive force and charge to storage battery (DC power supply 5).In actual applications in order to increase refrigeration work consumption and generated output, can make cooling pile and generating pile to this split type thermocouple parallel connection or series connection, as Fig. 2 is split type thermocouple series connection thermoelectric pile schematic diagram, and Fig. 3 is a split type thermocouple thermoelectric pile schematic diagram in parallel.
