Embodiment

Below in conjunction with Fig. 1 and embodiment the utility model is described in further detail:

Heat energy and kinetic transformation device embodiment, as shown in Figure 1 and Figure 2, comprise shell 1 and the baffle plate shell 5 that is arranged on the shell 1, and be arranged on the transmission shaft 4 in the shell 1, be provided with ten rotating shafts 2 on the described transmission shaft 4, described each rotating shaft 2 is provided with eight shape memory alloys 3; Described baffle plate shell 5 is provided with thermal source interface 51 and is used for the used heat outlet 52 of discharging used heat.Shell 1 is provided with the ratchet 13 with latch functions, so shape memory alloy 3 is merely able to turn clockwise; When shape memory alloy 3 is heated generation deformation stretching, extension by thermal source interface 51 after, promoting rotating shaft 2 turns clockwise, and can driving the shape memory alloy 3 that is arranged in the rotating shaft 2 when turning clockwise, rotating shaft 2 and then turns clockwise synchronously, like this, whole heat energy and kinetic transformation device have just rotated.

Because shape memory alloy 3 is the sheet shape memory alloys, hot area is limited, and behind the heat energy loss, the stretching, extension deformation of shape memory alloy 3 is little, and heat utilization rate is low.The utility model is for addressing this problem, and the side section of heat energy and kinetic transformation device is set to trapezium structure, and 5 are provided with an area of thermal source interface 51 less than an area that is provided with used heat outlet 52 on the described baffle plate shell; The length of the shape memory alloy 3 that described rotating shaft 2 is provided with is: the shape memory alloy 3 that is shorter than close used heat outlet 52 near the shape memory alloy 3 of thermal source interface 51.

The heat that heat inlet instant heating source interface 51 1 ends of this device pass into is larger, and area is less, and adapting to the shorter shape memory alloy 3 of setting, shape memory alloy 3 in the situation that heat intensity is large deformation occurs, and drives rotating shaft 2 and rotates; Loss along with heat energy, an end heat energy that passes into more close used heat outlet 52 in this device is less, less heat makes the deformation of shape memory alloy 3 also hand over little, at this moment the cross section with device enlarges, the shape memory alloy 3 that the setting that adapts is long, and long shape memory alloy 3 hot areas strengthen, when being subject to less heat energy, also can occur than large deformation, thereby produce larger kinetic energy, drive rotating shaft 2 and rotate, and then drive transmission shaft 4 rotations.

Shape memory alloy 3 is a panel, after being rotated counterclockwise 120 ° of bendings, form the first bending panel 31 and the second bending panel 32, through forming the 3rd bending panel 33 after the 120 ° of bendings that turn clockwise, the plane at the first bending panel 31 of the shape memory alloy 3 after bending is finished and the 3rd bending panel 33 places is parallel to each other again for the second bending panel 32.

Shape memory alloy 3 is fixedly connected with rotating shaft 2, and eight shape memory alloys 3 are evenly distributed in the rotating shaft 2 as the center of circle take the geometrical center of rotating shaft 2.The first bending panel 31 of shape memory alloy 3 is tangent with the circle that rotating shaft 2 axis projections become.Deformation can occur in shape memory alloy 3 after being heated, be in extended configuration, shape memory alloy 3 is subject to shell 1 top in the process that trails baffle plate shell 5 stops and acts on the baffle plate shell 5, baffle plate shell 5 promotes the reaction force that shape memory alloy 3 rotates for 3 one of shape memory alloys simultaneously, thereby generation moment, because shape memory alloy 3 and rotating shaft 2 are tangent and be fixedly connected with, eight shape memory alloys 3 successively act on, just can produce qualitative change by quantitative change, drive rotating shaft 2 and rotate.

Described ratchet 13 is arranged on the inwall middle part of baffle plate shell 5, the distance that the radial length during shape memory alloy 3 bending arrives between the rotating shaft 2 less than baffle plate shell 5, the distance that shape memory alloy 3 is arrived between the rotating shaft 2 greater than baffle plate shell 5 by the radial length behind the hot stretched; The degree of depth of solution shell 12 is subjected to radial length behind the hot stretched greater than shape memory alloy 3.Ratchet 13 is arranged on the inwall of baffle plate shell 5, and hot blast or hot gas are injected in the shell 1 by baffle plate shell 5, radiation on shape memory alloy 3, thereby so that shape memory alloy 3 is heated extends, and then promotes rotating shaft 2 and rotate.

The top of shell 1 is the baffle plate shell 5 that contacts with shape memory alloy 3 behind the expanded by heating, and the bottom of shell 1 is the solution shell 12 that cooling liquid 11 is housed.Shape memory alloy 3 contact with cooling liquid 11 in the solution shell 12 when the lower half portion of rotating to shell 1, and shape memory alloy 3 cools by cooling liquid 11, the original form of shape memory alloy 3 recoveries.Described shape memory alloy 3 is memory alloy, for example: can be titanium-nickel alloy.Memory alloy can produce distortion under external force, when external force is removed, under certain temperature conditions, can return to the original form, and have restore funcitons more than 1,000,000 times.Described shape memory alloy 3 returns to the front length of generation deformation through the cooling of cooling liquid 11, is subject to the drive of rotating shaft 2, again is heated, and deformation occurs, and promotes rotating shaft 2 and rotates, and formation circulates benignly.

The half of radius R 2 that does not have the thermal source radiation on the described baffle plate shell 5 more than or equal on the baffle plate shell with the half of radius R 1 of thermal source interface.Because shape memory alloy 3 contacts with baffle plate shell 5 after being heated and occuring to stretch, and also is subject to the drag effect of baffle plate shell 5 when deformation occurs, for reducing resistance, will there be the half of radius of thermal source radiation to increase in the present embodiment.

Thermal source interface 51 imports heat energy into, and memory shape memory alloy 3 expands because being heated, and shape memory alloy 3 will certainly extend after expanding, thereby is expressed to metal shell 1, because metal shell 1 can be out of shape because of extruding by unusual hard metal manufacturing.On the contrary, it can give the memory shape memory alloy 3 one reaction forces, and this reaction force can act in the rotating shaft 2 by memory shape memory alloy 3, thus the rotation of rotating shaft 2.Because the structure of metal shell 1 is that a first half radius is little, the device that the Lower Half radius is large when memory shape memory alloy 3 rotates to the bottom, will immerse in the cooling liquid 11, thereby memory shape memory alloy 3 shrinks, for secondary expanded by heating ready.In the situation that heat is arranged, shape memory alloy 3 drives rotating shafts 2 and rotates endlessly, for transmission shaft 4 brings endlessly power like this.

In a word, the above only is preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, for example: can there be different modes thermal source interface 51 set positions on shell 1, produce distortion as long as shape memory alloy 3 is heated, all should belong to the covering scope of the utility model patent.
