BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention is related to a heat generation assembly with heat removing structure and particularly to a heat generating component, which is associated with a cooling device, being capable of transferring the heat for lowering temperature of the heat generating part and supplying electric power.  
         [0003]     2. Brief Description of the Related Art  
         [0004]     Due to various apparatus frequently producing heat during being in operation, heat-removing device has to be utilized to dissipate the generated heat energy. The most currently used heat-removing device is the cooling fan. But, the cooling fan only dissipates limited amount of heat and extremely high temperature heat energy is incapable of being removed by the cooling fan and it often results in shutdown or damage of the product.  
         [0005]     Taiwanese Patent Official Gazette No. 260325 discloses an improved cooling and temperature control device, which provides a fan at the top of the cooling fins and a cooling device under the cooling fins. The cooling fins have a plurality of jut pieces at the surfaces thereof and the jut pieces are arranged in order on the surfaces with an end of the respective jut piece extending outward the respective cooling fin and the contact surface of the fan. In addition, a slot is provided at the cooling fins for being inserted with a control circuit board. Further, a temperature sensor  12  is disposed at an edge of a lower conductive plate  42  of the cooling device  40  such that the temperature sensor  12  contacts with a temperature controlled object to feed back a correct sensed temperature so as to reach a purpose of temperature control.  
         [0006]     However, the structure formed with the control circuit board, the temperature sensor and the cooling device has a cooing surface adhered a CPU and a heat dissipation surface joined to a fan for removing heat from the heat generating object. When the power is off, the residue electric charges still acts to the cooling device continuously to result in the cooling surface on the cooling device keeping sucking heat so as to occur condensation phenomenon and lead to short circuit. Further, the preceding improved cooling and temperature control device has to be supplied power for normal working so that the prior art obviously is unable to regenerate and reuse the energy under the condition of limited energy and material with high cost.  
         [0007]     Besides, the traditional art provides ceramic material to seal and pack the CPU with a metal upper cover and a radiator is joined to the metal upper cover. Heat source, which generates during the CPU being in operation, passes through the ceramic package and the metal cover and then the fan forces air to flow in a way of convection so as to cool the CPU. But, the prior art has the following shortcomings:  
         [0008]     1. The fan consumes a great deal of electrical energy and the preceding heat source is easy to increase the ambient temperature to influence heat dissipation of other parts.  
         [0009]     2. Large quantity of metal has to be used for making the fan, the metal cover and the heat dissipation device and it results in cost increase and resource waste.  
         [0010]     3. The preceding type cooling structure has to be changed design in accordance with heat increase rapidly resulting from higher clock frequency of the CPU and it takes long time before the product can be available on the market.  
       SUMMARY OF THE INVENTION  
       [0011]     An object of the present invention is to provide a heat generation assembly with heat removing structure in which an energy transfer part composed of a heat generating component associated with a cooling unit (or called cooling core, thermoelectric element, heat pump, Peltier cooler or thermoelectric cooler) to remove heat energy from the heat generating component by way of energy transfer function provided by the cooling unit and to offer power to other heat dissipation devices by way of electricity produced by the cooling device for saving resource.  
         [0012]     Another object of the present invention is to provide a heat generation assembly with heat removing structure with which heat from the heat generating component can be transmitted to the cooling unit directly to enhance effect of heat dissipation tremendously.  
         [0013]     A further object of the present invention is to provide a heat generation assembly with heat removing structure with which heat is moved to reduce temperature of the heat generating object.  
         [0014]     A further object of the present invention is to provide a heat generation device with heat removing structure with which the hot surface thereof contacts the heat generating object to prevent from short circuit due to condensation phenomenon resulting from the cold surface of the cooling device sucking heat continuously.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0021]     Referring to  FIGS. 1, 2  and  3 , the first embodiment of a heat generation assembly with cooling structure according to the present invention includes an energy transfer part  10 , a fan  20  and a heat removing block  30 . The energy transfer part  10  further includes a cooling unit  11  and a heat generating component  12 . The heat generating component  12  is joined to the cooling unit  11  with contacting, adhering or any other appropriate joining way and due to Peltier effect, heat conducts from a side of the cooling unit  11  to another side thereof to constitute temperature difference between a first substrate  111  (cold surface) and a second substrates  112  (hot surface) and the cooling unit  11  occurs energy transfer to allow heat changing to electric energy. That is, the heat generating component  12  is joined to the second substrate  112  and the cooling unit  11  occurs energy transfer to change the heat energy to the electric energy with the first substrate  111  providing the cold surface. The heat generating component  12  can be any type of heat generating object and a typical example of the heat generating component  12  is the central processing unit (CPU) in a computer, integrated circuit chip or signal amplifying assembly or a prior packed chip thereof or an exposed piece. Alternatively, the heat generating component  12  can be attached to a base  40 . Besides, the second substrate  112  can be provided with a recess  1120  to receive the heat generating component  12  as shown in  FIG. 4  or the heat generating component  12  with a packing body is joined to the cooling unit  11  as shown in  FIG. 5  without the second substrate  112 .  
         [0022]     Besides, the cooling unit  11  can provide a conductive member  13  for connecting with fan  20  or any other periphery device directly or indirectly and the fan  20  is driven with the electric energy produced by the cold unit  11 .  
         [0023]     The cooling unit  11  can contact with or is joined to the heat removing block  30  with the first substrate  111  (cold surface) thereof such that low temperature at the first substrate  111  can be conducted to the heat removing block  30 . The fan  20  can be attached to the heat removing block  30  to drive or guide cooler air after passing through the heat removing block  30  toward other parts performing heat exchange or lowering the whole ambient temperature. In this way, it is capable of lowering working temperature of the heat generating component  12  and recycling or utilizing energy.  
         [0024]     As the foregoing, the heat generation assembly with cooling structure according to the present invention has the following advantages:  
         [0025]     1. Non-packed heat generating component  12  contacting with the cold unit  11  allows heat of the heat generating component  12  being transmitted to the cooling unit  11  with part of heat dissipating to the air so that packing cost can be lowered in addition to better heat transfer being obtained and deficiency of conventional packing technique not easy to remove heat being overcome.  
         [0026]     2. Due to the energy transfer part  10  providing energy change, electricity created can be used by other heat dissipation devices to utilize energy sufficiently such that it is not necessary to provide external power supply and the production cost can be reduced.  
         [0027]     3. The cooling unit  11  contacting with the heat generating object with the hot surface thereof can overcome problem of condensation occurring in the conventional art during power off to avoid short circuit so that it enhances work safety.  
         [0028]     4. The air cooled by the cold surface of the energy transfer part  10  performs heat exchange with other parts or lowers down the whole ambient temperature so that the fan  20  and the heat removing block  30  can provide smaller surface areas to reduce material cost. Further, it is not necessary for the fan  20  to run under the full power so that it is able to extend life span of the fan.  
         [0029]     5. The present invention is suitable for different heat generating components  12  so that it is not required to redesign heat dissipation device for the specific heat generating component  12  and cost for research and development can be saved tremendously.  
         [0030]     While the invention has been described with referencing to preferred embodiments thereof, it is to be understood that modifications or variations may be easily made without departing from the spirit of this invention, which is defined by the appended claims.
