     DETAILED DESCRIPTION 
       [0010]    It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features of the present disclosure. 
         [0011]    Several definitions that apply throughout this disclosure will now be presented. 
         [0012]    The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or other feature that the term modifies, such that the component need not be exact. For example, “substantially cylindrical” means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like. 
         [0013]    The present disclosure is described in relation to a heat dissipation device. 
         [0014]      FIGS. 1-4  illustrate one embodiment of a heat dissipation device. The heat dissipation device includes a heat dissipating member  10 , a fan  20 , a water pipe  30 , a water drawing device  40 , a motor  50 , and a heat exchanging plate  60 . 
         [0015]    The heat dissipating member  10  defines a plurality of vents  12 , a water inlet  16 , and a water outlet  18 . The heat dissipating member  10  includes a plurality of fins  14 . The fins of the plurality of fins  14  are substantially parallel to each other. The vents of the plurality of vents  12  are spaced from each other. Each fin  14  is located between two vents  12 . Each fin  14  defines a guiding channel  142 . The guiding channels of the plurality of guiding channels  142  connect to each other. The water inlet  16  and the water outlet  18  connect to the guiding channels  142 . 
         [0016]    The fan  20  includes a body  21  and a frame  22 . The water pipe  30  includes an inlet pipe  32  and an outlet pipe  34 . The water drawing device  40  includes a shell  42 , a guiding piece  44 , and a plurality of blades  46 . The guiding piece  44  is engaged with the shell  42 . The motor  50  includes a shaft  52 . The heat exchanging plate  60  defines a plurality of holes  62 . 
         [0017]      FIG. 3-FIG .  5  show views of the assembled heat dissipation device. The plurality of blades  46  is engaged with the shaft  52 . The plurality of blades  46  and the shaft  52  are located in the shell  42 . One end of the inlet pipe  32  connects to the water inlet  16  and an opposite end of the inlet pipe  32  connects to the shell  42 . One end of the outlet pipe  34  connects to the water outlet  18  and an opposite end of the outlet pipe  34  connects to the shell  42 . The shell  42 , the inlet pipe  32 , the outlet pipe  34 , and the guiding channels  142  cooperatively define a loop. The guiding piece  44  is located on a joint of the inlet pipe  32  and the shell  42 . The body  21  is mounted on an end of the shaft  52 . The frame  22  of the fan  20  is fixed to the heat dissipating member  10 . The fan  20  is located between the heat dissipating member  10  and the water drawing device  40 . The heat dissipating member  10 , the fan  20 , and the motor  50  are secured to the heat exchanging plate  60 . The heat exchanging plate  60  is secured to an electronic device by the plurality of holes  62 . 
         [0018]    In use, the shaft  52  is forced to rotate by the motor  50 . The motor  50  rotates the plurality of blades  46 . The fan  20  generates an airflow through the plurality of vents  12  of the heat dissipating member  10 , to cool the plurality of fins  14 . The direction of the airflow is substantially perpendicular to an extending direction of each fin  14 . The plurality of blades  46  pumps the water from the outlet pipe  34  and draws the water back to the inlet pipe  32 . The guiding piece  44  guides the water flow into the inlet pipe  32 . The water in the inlet pipe  32  flows through the guiding channel  142  to cool the plurality of fins  14 . The water in the guiding channel  142  flows through the outlet pipe  34  and back to the water drawing device  40 . 
         [0019]    The embodiments shown and described above are only examples. Many details are often found in the art such as the other features of a heat dissipation device. Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, especially in matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the embodiments described above may be modified within the scope of the claims.
