     DETAILED DESCRIPTION 
     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 have been exaggerated to better illustrate details and features of the present disclosure. 
     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. 
       FIG. 1  illustrates one embodiment of a cooling module  100 . The cooling module  100  is configured to cool an electronic component  25  installed in a chassis  10  (shown in  FIG. 4 ). The cooling module  100  includes a radiator  40 , a fan module  50  and a heat dissipating member  60  fixed on the radiator  40 . 
       FIGS. 1 and 2  illustrate the chassis  10  includes a base  20  and a cover plate  30  fixed on the base  20 . A motherboard  21  is located on the base  20 . The electronic component  25  is fixed on the motherboard  21 . The motherboard  21  defines a plurality of fixing holes  211  around the electronic component  25 . The base  20  includes a front plate  22  and a rear plate  23  parallel to the front plate  22 . The front plate  22  defines a plurality of air inlets  221 . The rear plate  23  defines a plurality of air outlets  231 . The cover plate  30  can be fixed on the base  20 . The base  20  and the cover plate  30  cooperatively define a receiving space  26 . In at least one embodiment, the electronic component  25  is a Central Processing Unit (CPU). 
     The radiator  40  includes an heat sink  41 , a heat pipe  42  and a radiator portion  43 . The heat sink  41  includes a base plate  411  and a plurality of fins  45  fixed on the base plate  411 . Three fixing portions  412  are located around the base plate  411 . The fixing portion  412  defines a through hole  413 . One fixing piece  45  can pass through the through hole  413  and be inserted into the fixing hole  211  to fix the radiator  40  on the motherboard  21 . The fins  415  are parallel to each other and are substantially perpendicular to the base plate  411 . 
     One end of the heat pipe  42  is received in the heat sink  41  and another end of the heat pipe  42  is received in the radiator portion  43 . The heat pipe  42  receives coolant (not shown). The coolant can absorb heat of the heat sink  41  and transfer heat to the radiator portion  43 . The radiator portion  43  is fixed on the motherboard  21 . 
     The fan module  50  includes a fixing bracket  51  and a cooling fan  55  received in the fixing bracket  51 . A plurality of securing members  52  can pass through the fixing bracket  51  to fix the fan module  50  on the motherboard  21 . The fixing bracket  51  defines a plurality of openings  511  and an air vent  512 . The radiator portion  43  is aligned with the air vent  512 . Airflow can enter into the fan module  50  through the opening  511  and exit the fan module  50  via the air vent  512 . 
     The heat dissipating member  60  includes an absorption end  61  and a radiating end  62 . The absorption end  61  can be fixed on the heat sink  41 . The absorption end  61  defines three notches  611 . The radiating end  62  is covering the fan module  50  and is aligned with the opening  511 . A gap is formed between the radiating end  62  and the opening  511  which is configured to let the airflow pass through. The absorption end  61  is near to the heat sink  41  to absorb heat of the heat sink  41  and transfer the heat to the radiating end  62 . 
       FIGS. 3 and 4  illustrate when in assembly, the radiator  40  is placed in the receiving space  26  and is supported on the motherboard  21 . The base plate  411  is near to the electronic component  25 . The through hole  413  is aligned with the fixing hole  211 . The fixing piece  45  passes through the through hole  413  and is inserted into the fixing hole  211  to fix the radiator  40  on the motherboard  21 . The fan module  50  is placed in the receiving space  26 . The air vent  512  is aligned with the radiator portion  43 . The securing member  52  passes through the fixing bracket  51  to fix the fan module  50  on the motherboard  21 . The heat dissipating member  60  is placed on the radiator  40 . The absorption end  61  is fixed on the heat sink  41 . The radiating end  62  is covered on the opening  511 . Then, the cooling module  100  is completely assembled. The cover plate  30  is fixed on the base  20  and the chassis  10  is completely assembled. 
     When the electronic component  25  is working, the base plate  411  absorbs the heat of the electronic component  25  and transfers the heat to the fins  415 . Some of heat of the fins  415  is transferred to the heat pipe  42  and some of heat of the fins  415  is transferred to the absorption end  61 . The coolant within the heat pipe  42  absorbs heat and transfers heat to the radiator portion  43 . The absorption end  61  transfers heat to the radiating end  62 . Airflow enters into the chassis through the air inlets  221 , and enters into the fan module  50  after passing through the radiating end  62 . Then, the airflow passes through the air vents  512  and the radiator portion  43  under the drive of cooling fan  55 . Finally, the airflow leaves the chassis  10  from the air outlets  231  to dissipate heat from the electronic component  25 . 
     It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
