Should be understood that for above-mentioned arbitrary embodiment, vehicle 10 and/or energy collecting system 42,142 can comprise a plurality of hot machines 16,116 and/or a plurality of assembly 20.That is to say that vehicle 10 can comprise hot machine 16,116 and/or the assembly 20 more than.For example, hot machine 16,116 can drive the assembly 20 more than.Similarly, vehicle 10 can comprise the energy collecting system 42,142 more than, and each has a hot machine 16,116 and assembly 20 at least.A plurality of hot machines 16,116 can utilize the temperature difference in a plurality of zones that spread all over vehicle 10.
Referring now to Fig. 1 and Fig. 2,, hot machine 16 be configured to be used for heat energy for example heat deflection be mechanical energy or be mechanical energy with heat deflection and then be transformed into electric energy, hereinafter will describe in detail.Hot machine 16 comprises marmem 18 (as Fig. 2), and marmem 18 has under the specified temp that exposes transformable crystallised phase between austenite and martensite in its at first area 12 and second area 14.In response to the temperature difference (as Fig. 1) of first area 12 and second area 14, marmem stands crystallised phase between through first area 12 and second area 14 time to be changed.Following description is with reference to figure 2.But all embodiments' marmem 18 is all implemented in a similar fashion.
As use herein, term " marmem " refers to show the alloy of shape memory effect.That is to say that marmem 18 rearranges by molecule can stand solid state phase changesization being that " martensite " and austenite are to change between " austenite " mutually at martensitic phase.In other words, marmem 18 can stand that shift-type changes rather than diffusion-type transition between martensite and austenite, to change.In general, martensitic phase refers to the phase of relatively lower temp and usually than the austenite of relative higher temperature easy deformation mutually.Marmem 18 begin from austenite in opposite directions the temperature that changes of martensitic phase be known as martensite start temperature M
SMarmem 18 finish from austenite in opposite directions the temperature that changes of martensitic phase be known as martensite and finish temperature M
fSimilarly, when marmem 18 was heated, marmem 18 began to be known as austenite initial temperature A from the temperature that martensitic phase changes mutually to austenite
sAnd marmem 18 is finished the temperature that changes mutually to austenite from martensitic phase and is known as austenite and finishes temperature A
f
Therefore, marmem 18 can be characterized as being cold conditions, that is, temperature M finished in the martensite that is lower than marmem 18 when the temperature of marmem 18
fThe time.Similarly, marmem 18 can also be characterized as being hot, that is, the austenite that is higher than marmem 18 when the temperature of marmem 18 is finished temperature A
fThe time.
When operation, just when being exposed to the temperature difference of first area 12 and second area 14, marmem 18 if be subjected to prestrain or stand tensile stress, can varying sizedly when crystallised phase changes be converted into mechanical energy with heat energy thus.That is to say, if be subjected to pseudoplastic behavior prestrain, then marmem 18 can with crystallised phase from martensite change to austenite and thus dimensional contraction so that heat energy is converted into mechanical energy.On the contrary, if under stress, marmem 18 can with crystallised phase from austenite change to martensite and thus size expansion so that heat energy is converted into mechanical energy.
Pseudoplastic behavior prestrain is meant that extended configuration memory alloy 18 makes the strain that marmem 18 shows under loading environment not recover fully when being in martensitic phase when unloading, wherein pure elastic strain can be recovered fully.With regard to marmem 18, can add carrier material and make surpass elastic strain limit and before surpassing the real plastic strain limit of material, in the martensitic crystalline structure at material deformation takes place.Such strain between these two limit, it is the pseudoplastic behavior strain, address is because it shows and has plastic deformation in when unloading like this, but when heating reaches marmem 18 and changes the point of its austenite phase into, this strain can recover, thereby makes marmem 18 turn back to observed initial length before applying any load.Marmem 18 was made the nominal length of marmem 18 include recoverable pseudoplastic behavior strain by stretching, extension before being installed to hot machine 18 usually, and it provides the motion in order to the hot machine 16 of actuating/driving.Under the situation that does not have pre-extended configuration memory alloy 18, in phase transition process, can only see less deformed.
In addition, marmem 18 can have any suitable form, i.e. shape.Such as, marmem 18 can have from comprising bias component (as spring), winding, line, band, the form of selecting in the group of continuous loop and their combination.Referring to Fig. 2, in a kind of modification, marmem 18 can form the continuous loop spring.
In addition, thus marmem 18 can change modulus when crystallised phase changes and size changes heat energy into mechanical energy.More specifically, marmem 18, if pseudoplastic prestrain, but then in crystallised phase dimensional contraction when Martensitic transformation is austenite, if and can size stretch during for martensite from austenitic transformation in crystallised phase in that tensile stress is next, thereby change heat energy into mechanical energy.Therefore, between second temperature of first temperature of first area 12 and second area 14, exist under any condition of the temperature difference, be that first area 12 and second area 14 are not under the thermally equilibrated condition, but marmem 18 sizes stretch or shrink when crystallised phase changes between martensite and Ao Shi body.And the transformation of the crystallised phase of marmem 18 can impel marmem rotary pulley 24,26 (as shown in Figure 2) thereby driven unit 20.
