     This application claims the benefit of priority to Taiwan Patent Application No. 108107335, filed on Mar. 6, 2019. The entire content of the above identified application is incorporated herein by reference. 
     Some references, which may include patents, patent applications and various publications, may be cited and discussed in the description of this disclosure. The citation and/or discussion of such references is provided merely to clarify the description of the present disclosure and is not an admission that any such reference is “prior art” to the disclosure described herein. All references cited and discussed in this specification are incorporated herein by reference in their entireties and to the same extent as if each reference was individually incorporated by reference. 
     FIELD OF THE DISCLOSURE 
     The present disclosure relates to a fluid driving device, and more particularly to a fluid driving device that does not use thermal energy or mechanical fan rotation as driving power. 
     BACKGROUND OF THE DISCLOSURE 
     In the conventional fluid driving devices, for example, a heat pipe promotes the flow of a fluid therein through the absorption and dissipation of thermal energy to achieve a heat dissipation effect. In addition, an engine or a steam engine drives other devices by converting thermal energy into mechanical energy. In terms of fluid driving methods, the form of energy desired by users can be used only after the thermal energy is absorbed or dissipated by the fluid. 
     However, conventional sources for heating are still mainly combustible energy sources such as oil, gas, and natural gas. In the near future, these combustible energy sources would be gradually exhausted, which may result in a considerable impact on people&#39;s lives. 
     Therefore, it is an important issue in the industry to provide a device that drives a fluid without using thermal energy. 
     SUMMARY OF THE DISCLOSURE 
     In response to the above-referenced technical inadequacies, the present disclosure provides a fluid driving device. The fluid driving device includes: a receiving body having a first side and a second side, wherein the first side and the second side are disposed opposite to each other, a fluid is received in the receiving body, and the receiving body is elastic; a first magnetic force generating module disposed on the first side; and a second magnetic force generating module disposed on the second side. The interaction between the first magnetic force generating module and the second magnetic force generating module causes a deformation of the receiving body to drive the fluid to flow. 
     In the present disclosure, the magnetic force generating module is controlled by electric energy, and the receiving body of the fluid driving device is deformed through the attraction and repulsion of the magnetic force, thereby driving the fluid in the receiving body. The use of thermal energy can be effectively reduced, and the velocity and direction of the fluid can be controlled through the deformation of the receiving body. 
     These and other aspects of the present disclosure will become apparent from the following description of the embodiment taken in conjunction with the following drawings and their captions, although variations and modifications therein may be affected without departing from the spirit and scope of the novel concepts of the disclosure.

In  FIG. 1 , the inner diameter of the receiving body  10  is an initial distance d 0 . 
     Furthermore, one of the magnetic force generating units  201 - 206  of the first magnetic force generating module  20  is a first magnetic pole. One of the plurality of magnetic force generating units  301 - 306  of the second magnetic force generating module  30  disposed on the opposite side is a second magnetic pole, and the first magnetic pole and the second magnetic pole have the same polarity (both are S poles or N poles), and therefore repel each other.

An inner diameter of a pipe-wall region of the receiving body  10  provided with one of the plurality of magnetic force generating units  201 - 206  of the first magnetic force generating module  20  and the plurality of magnetic force generating units  301 - 306  of the second magnetic force generating module  30  is decreased. 
     Referring to  FIG. 2 ,  FIG. 2  is a schematic diagram of the interaction between a first magnetic force generating module and a second magnetic force generating module of the fluid driving device according to the embodiment of the present disclosure. 
     A plurality of magnetic poles of the plurality of magnetic force generating units  201 - 206  of the first magnetic force generating module  20  are N poles. A plurality of magnetic poles of the plurality of magnetic force generating units  301 - 306  of the second magnetic force generating module  30  are S poles. The plurality of magnetic poles of the first magnetic force generating module  20  and the plurality of magnetic poles of the second magnetic force generating module  30  are different magnetic poles, and therefore attract each other. In this embodiment, the first magnetic force generating module  20  and the second magnetic force generating module  30  are disposed in the pipe wall of the receiving body  10 , and therefore, the pipe walls on both sides of the receiving body  10  are close to each other due to the attracting magnetic force. In this case, the inner diameter of the receiving body  10  is a first distance d 1 . The first distance d 1  is less than the initial distance d 0 .

In this embodiment, the first magnetic force generating module  20  and the second magnetic force generating module  30  are disposed in the pipe wall of the receiving body  10 , and therefore, the pipe walls on both sides of the receiving body  10  are close to each other due to the repelling magnetic force. In this case, the inner diameter of the receiving body  10  is a second distance d 2 . The second distance d 2  is greater than the initial distance d 0  and the first distance d 1 . 
     Referring to  FIG. 4 ,  FIG. 4  is yet another schematic diagram of the interaction between the first magnetic force generating module and the second magnetic force generating module of the fluid driving device according to the embodiment of the present disclosure. 
     In this embodiment, the magnetic poles of the first magnetic force generating unit  201 , the second magnetic force generating unit  202 , and the third magnetic force generating unit  203  of the first magnetic force generating module  20  are N poles. The magnetic poles of the fourth magnetic force generating unit  204 , the fifth magnetic force generating unit  205 , and the sixth magnetic force generating unit  206  of the first magnetic force generating module  20  are S poles.

     That is, the magnetic poles of the first magnetic force generating unit  201 , the second magnetic force generating unit  202 , and the third magnetic force generating unit  203 , and the magnetic poles of the seventh magnetic force generating unit  301 , the eighth magnetic force generating unit  302 , and the ninth magnetic force generating unit  303  are different magnetic poles, and therefore attract each other. Therefore, the inner diameter of the pipe-wall region where the first magnetic force generating unit  201 , the second magnetic force generating unit  202 , the third magnetic force generating unit  203 , the seventh magnetic force generating unit  301 , the eighth magnetic force unit  302 , and the ninth magnetic force generating unit  303  are disposed is decreased. 
     The magnetic poles of the fourth magnetic force generating unit  204 , the fifth magnetic force generating unit  205 , and the sixth magnetic force generating unit  206 , and the magnetic poles of the tenth magnetic force generating unit  304 , the eleventh magnetic force generating unit  305 , and the twelfth magnetic force generating unit  306  are the same magnetic poles, and therefore repel each other. Therefore, the inner diameter of the pipe-wall region where the fourth magnetic force generating unit  204 , the fifth magnetic force generating unit  205 , the sixth magnetic force generating unit  206 , the tenth magnetic force generating unit  304 , the eleventh magnetic force unit  305 , and the twelfth magnetic force generating unit  306  are disposed is increased. In this embodiment, the distance between the first magnetic force generating unit  201 , the second magnetic force generating unit  202 , and the third magnetic force generating unit  203 , and that of the seventh magnetic force generating unit  301 , the eighth magnetic force unit  302 , and the ninth magnetic force generating unit  303  is a third distance d 3 .

That is, the magnetic force generating units  201 - 206  and the magnetic force generating units  301 - 306  include at least one coil and a conductor. 
     Referring to  FIG. 5 ,  FIG. 5  is a functional block diagram of the fluid driving device according to the embodiment of the present disclosure. 
     In this embodiment, the fluid driving device  1  further includes a power supply module  50  and a control module  60 . The control module  60  is electrically connected to the power supply module  50 . The power supply module  50  is electrically connected to the first magnetic force generating module  20  and the second magnetic force generating module  30 . 
     The power supply module provides power to each of the plurality of magnetic force generating units of the first magnetic force generating module  20  and the second magnetic force generating module  30  to generate a plurality of magnetic poles. 
     In this embodiment, the inner diameter of the pipe body of the receiving body  10  can be increased or decreased by each of the plurality of magnetic force generating units of the first magnetic force generating module  20  and the second magnetic force generating module  30 . Therefore, the fluid in the receiving body  10  can flow in different directions and at different velocities by changing the space inside the receiving body  10 . 
     In this embodiment, the control module  60  provides a control signal to the power supply module  50 . The voltage magnitude and the current direction, etc. provided by the power supply module  50  to the first magnetic module  20  and the second magnetic module  30  can be controlled to control the plurality of magnetic force generating units of the first magnetic module  20  and the second magnetic module  30  to generate different magnetic poles, different magnitudes of magnetic force, different magnetic pole arrangements, and the changing order of different magnetic poles. 
     That is, the power supply module  50  provides power to the first magnetic force generating module  20  and the second magnetic force generating module  30  according to the control signal. 
     In this embodiment, the first side  10 A or the second side  10 B of the receiving body  10  is fixedly disposed on a fixed point or a plane. That is, taking the first side  10 A or the second side  10 B of the receiving body  10  as a reference point, the deformation of the receiving body  10  can be further calculated and planned. 
     Referring to  FIGS. 6A and 6B ,  FIG. 6A  is still another schematic diagram of the interaction between the first magnetic force generating module and the second magnetic force generating module of the fluid driving device according to the embodiment of the present disclosure.  FIG. 6B  is still another schematic diagram of the interaction between the first magnetic force generating module and the second magnetic force generating module of the fluid driving device according to the embodiment of the present disclosure. 
     For ease of illustration, in this embodiment, the magnetic poles of the plurality of magnetic force generating units  301 - 306  of the second magnetic force generating module  30  are S poles. Therefore, the plurality of magnetic poles of the second magnetic force generating module  30  are presented as S poles. In other embodiments, the plurality of magnetic poles of the first magnetic force generating module  20  can be preset to have the same polarity. It is also possible not to set any preset value. 
     In this embodiment, the second side  10 B of the receiving body  10  is fixedly disposed on a fixed point or a plane. Therefore, the change in the inner diameter of the receiving body  10  can be clearly observed. 
     As shown in  FIG. 6A , a region between the second magnetic force generating unit  202 , the third magnetic force generating unit  203 , the ninth magnetic force generating unit  303 , and the tenth magnetic force generating unit  304  is greater than a region between other magnetic force generating units. 
     In this case, the magnetic pole of the second magnetic force generating unit  202  changes, and is converted from the S pole to the N pole. The fluid between the second magnetic force generating unit  202  and the eighth magnetic force generating unit  302  is squeezed to move toward the direction of the third magnetic force generating unit  203  and the ninth magnetic force generating unit  303 . In this case, the magnetic force between the first magnetic force generating unit  201  and the seventh magnetic force generating unit  301  needs to be increased to cause the fluid to move toward the direction of the third magnetic force generating unit  203  and the ninth magnetic force generating unit  303 . In this embodiment, the inner diameter of the receiving body  10  can be increased or decreased through the magnetic force generated by the first magnetic force generating module  20  and the second magnetic force generating module  30 , that is, the cross-sectional area inside the receiving body  10  is changed. That is, the cross-sectional area of the receiving body  10  is a non-linear function value of the magnetic force generated by the first magnetic force generating module  20  and the second magnetic force generating module  30 , as shown in the following formula 1: 
       Area=Func( F mag)  Formula 1.
 
     In formula 1, Area is the cross-sectional area inside the receiving body  10 , and Fmag is the magnetic force generated between a plurality of magnetic force generating units. 
     In this embodiment, the magnetic force between a plurality of magnetic force generating units can be changed in magnitude according to the power provided by the power supply module  50 . Therefore, the magnetic force Fmag can also be divided into a plurality of levels. 
     Furthermore, since the cross-sectional area of the receiving body  10  is changed, the velocity of the fluid is affected. 
     That is, the fluid in the receiving body  10  follows the following formula 2. Formula 2 is the relationship between the velocity of the fluid in a continuous container and the cross-sectional area, as follows: 
         A 1* V 1= A 2* V 2  Formula 2.
 
     It can be known from formula 2 that the velocity of the fluid is in inverse proportion with the cross-sectional area of the container through which the fluid flows. That is, the larger the cross-sectional area is, the slower the fluid velocity is. The smaller the cross-sectional area is, the faster the fluid velocity is. 
     In this embodiment, the flow direction and velocity of the fluid in the receiving body  10  can be effectively controlled by controlling the magnitude of the magnetic force and the change order of the magnetic poles. 
     In this embodiment, the number and setting positions of the receiving bodies  10 , the magnetic force generating modules, the magnetic force generating units can be adjusted and designed according to actual needs, and is not limited in the present disclosure. 
     Since the fluid in the receiving body  10  can be gas or liquid, the fluid driving device  1  of the present disclosure can be used in a heat dissipation system to effectively control the efficiency of heat dissipation through the movement of the gas or liquid. 
     Moreover, since the driving of the gas or liquid can also be used as a power source, it can be used as a power source for underwater transport equipment, waterborne equipment, or airborne equipment. 
     Referring to  FIG. 7 ,  FIG. 7  is a cross-sectional diagram of the fluid driving device taken along section line VII-VII of  FIG. 1 . 
     In this embodiment, the fluid driving device  1 ′ includes a receiving body  10 ′, a first magnetic force generating module  20 ′, a second magnetic force generating module  30 ′, a third magnetic force generating module  40 ′, a fourth magnetic force generating module  50 ′, a fifth magnetic force generating module  60 ′, a sixth magnetic force generating module  70 ′, a seventh magnetic force generating module  80 ′, and an eighth magnetic force generating module  90 ′. 
     In this embodiment, the first magnetic force generating module  20 ′, the second magnetic force generating module  30 ′, the third magnetic force generating module  40 ′, the fourth magnetic force generating module  50 ′, the fifth magnetic force generating module  60 ′, the sixth magnetic force generating module  70 ′, the seventh magnetic force generating module  80 ′, and the eighth magnetic force generating module  90 ′ are disposed opposite and pairwise to each other in the receiving body  10 ′. That is, the first magnetic force generating module  20 ′ is disposed opposite to the fifth magnetic force generating module  60 ′. The second magnetic force generating module  30 ′ is disposed opposite to the sixth magnetic force generating module  70 ′. The third magnetic force generating module  40 ′ is disposed opposite to the seventh magnetic force generating module  80 ′. The fourth magnetic force generating module  50 ′ is disposed opposite to the eighth magnetic force generating module  90 ′. 
     In this embodiment, the magnetic force adjustment mode of each magnetic force generating module can be more flexible. As shown in  FIG. 7 , the magnetic pole of the first magnetic force generating module  20 ′ can be used as a reference to adjust the magnetic poles and the magnitudes of magnetic force of other magnetic force generating modules. 
     In this embodiment, the volume change of the receiving body  10 ′ can be accelerated, increased or adjusted by adopting a plurality of sets of magnetic force generating modules to effectively adjust the velocity of the fluid in the receiving body  10 ′, thereby increasing the forward force or setback force of the fluid. 
     Advantageous Effects of Embodiments 
     In the present disclosure, the magnetic force generating module is controlled by electric energy, and the receiving body of the fluid driving device is deformed through the attraction and repulsion of the magnetic force, thereby driving the fluid in the receiving body. Therefore, the use of thermal energy can be effectively reduced, and the velocity and direction of the fluid can be controlled through the deformation of the receiving body.
