BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention generally relates to a heat conduction technology, and more particularly to a heat conducting apparatus in contact with two objects for conducting heat from one of the two objects to another. 
     2. Description of Prior Art 
     Heat dissipation is a major factor affecting the normal operation of a computer or a multimedia related device, and thus heat dissipation solutions play a substantially important role of fulfilling the increasingly higher demand of computer functions. 
     In addition to the basic requirement of dissipating heat produced by a heat generating source, computer manufacturers also tend to develop desktop or notebook computers with high heat dissipating efficiency. However, the design of desktop or notebook computers have to follow a specification, and thus heat dissipating structures or devices are installed at specific positions of a computer, and manufacturers need to provide solutions to improve the heat dissipating efficiency according to the various different specifications or internal structures of different models, and sometimes they have to make a redesign. For industrial computers, the position of installing a heat generating component in an industrial computer varies with different models and functions, manufacturers have to custom make different heat dissipating structures or devices, and even install a heat conducting structure between a heat generating source and a heat dissipating body to achieve a thermal conduction for dissipating the heat produced by the heat generating source to the outside. In the past, an object of such heat conducting structure was made of copper or aluminum and in a form of heat conducting block of a required size. The heat conducting block is in contact with the heat generating source and the heat dissipating body for conducting heat. However, after a single heat conducting block is produced as a finished good according to a specific interval, the produced heat conducting block cannot be used for other intervals. Furthermore, there is an unavoidable tolerance and even a manufacturing error occurred when a product is manufactured, a single heat conducting block cannot be adjusted to fit the actual size of the finished good. The heat conducting block cannot be used if the size of the heat conducting block is too large, or the heat conducting effect will be affected by a forming gap if the size of the heat conducting block is too small. 
     In view of the foregoing shortcomings of the prior art, the inventor of the present invention based on years of experience in the related industry to conduct extensive researches and experiments, and finally developed a heat conducting apparatus in accordance with the present invention to overcome the shortcomings of the prior art. 
     SUMMARY OF THE INVENTION 
     It is a primary objective of the invention to adopt a design of two slide blocks each with an oblique plane, and the two slide blocks are kept in contact with two objects such as a heat generating source and a heat dissipating body respectively for conducting the heat produced by the heat generating source to the heat dissipating body. In the design of the slide blocks, the height difference between the heat generating source and the heat dissipating body can be adjusted freely to comply with the design and provide a close contact between the heat generating source and the heat dissipating body for a good heat conducting effect. 
     To achieve the foregoing objective, the present invention provides a heat conducting apparatus in contact with two objects for dissipating heat, and the heat conducting apparatus comprises a base, a first heat conducting block and a second heat conducting block, wherein the base includes a containing space with an open top and an open bottom for installing a first heat conducting block, and the first heat conducting block has a first oblique plane facing the top of the base, and the second heat conducting block has a second oblique plane corresponding to the first oblique plane, and the second heat conducting block is stacked onto the top of the first heat conducting block. With a slide movement between the two oblique planes of the first and second heat conducting blocks, the interval between the two objects can be adjusted, so that the bottom of the first heat conducting block and the top of the second heat conducting block are in contact with the two objects respectively.

     DETAILED DESCRIPTION OF THE INVENTION 
     The technical characteristics, features and advantages of the present invention will become apparent in the following detailed description of preferred embodiments with reference to the accompanying drawings, and the preferred embodiments are used for illustrating the present invention only, but not intended to limit the scope of the present invention. 
     In  FIGS. 1 and 2 , the present invention provides a heat conducting apparatus  1  in contact with two objects such as a heat generating component  200  and a heat dissipating plate  21 , and the heat conducting apparatus  1  conducts the heat produced by the heat generating component  200  to the heat dissipating plate  21  and dissipates the heat to the outside. 
     In a preferred embodiment of the present invention, the heat conducting apparatus  1  is installed in an industrial computer  2  (but not limited to the industrial computer  2  only). The industrial computer  2  contains a motherboard  20  therein, and the motherboard  20  comprises a heat generating component  200  and a heat dissipating plate  21  disposed in the industrial computer  2  and at a position corresponding to the top of the motherboard  20 . The industrial computer  2  comprises: two heat dissipating covers  22 , each of which is a portion of a casing of the industrial computer  2 , exposed to the outside and disposed with a gap between each other, and made of a metal with a good heat dissipating effect; and a plurality of heat sink  220  disposed on an external lateral sides of the heat dissipating covers  22 , such that a heat pipe  210  can be used for contacting and conducting the heat between the heat dissipating plate  21  and the heat dissipating cover  22  to dissipate the heat to the outside. The heat conducting apparatus  1  installed and coupled between the heat generating component  200  and the heat dissipating plate  21  conducts the heat produced by the heat generating component  200  to the heat dissipating plate  21  and then through the heat pipe  210  of the heat dissipating plate  21  for a quick thermal conduction, so as to conduct the heat to the two heat dissipating covers  22  through the heat pipe  210  and dissipate the heat to the outside. 
     In  FIGS. 3 and 4 , the heat conducting apparatus  1  comprises a base  10 , a first heat conducting block  11 , and a second heat conducting block  12 . 
     The base  10  is provided for positioning the first and second heat conducting blocks  11 ,  12  to maintain a contact between the two heat conducting blocks  11 ,  12  as shown in  FIG. 5 . The base  10  is a frame made by a plurality of sidewalls  100 , and a containing space  101  is formed in the base  10  for installing the first heat conducting block  11 . The containing space  101  of the base  10  has an open top and an open bottom, such that the first heat conducting block  11  installed at the open top is corresponding to the second heat conducting block  12 , and the open bottom is provided for contacting a desired object for conducting heat. The base  10  further includes a fixing portion  102  protruded horizontally towards an external side, and each fixing portion  102  is a plate object for installing and positioning the motherboard  2  to facilitate fixing the base  10  onto the motherboard  2  and at a position corresponding to the heat generating component  200 . 
     The first heat conducting block  11  accommodated in the containing space  101  of the base  10  includes a first oblique plane  110  facing the top of the base  10 , and the bottom of the first heat conducting block  11  is a plane  111  for attaching and contacting the heat generating component  200  to absorb the heat produced by the heat generating component  200 . The lateral sides of the first heat conducting block  11  and each sidewall  100  of the base  10  include a plurality of locking holes  112 , and the sidewalls  100  of the base  10  include a plurality of adjusting holes  104  corresponding to the plurality of locking holes  112 , respectively, and each adjusting hole  104  is in a shape of a rectangular bar extending upward and downward for adjusting the height and position of the first heat conducting block  11  of the base  10  when the first heat conducting block  11  is installed to the base  10 . After a fixing element  105  such as a bolt is passed through the adjusting hole  104  and secured into the locking hole  112 , the first heat conducting block  11  is fixed into the containing space  101  of the base  10 . 
     The second heat conducting block  12  stacked onto the top of the first heat conducting block  11  includes an oblique plane  110  of the first heat conducting block  11  corresponding to and in contact with the second oblique plane  120 , and the second oblique plane  120  is disposed at the bottom of the second heat conducting block  12 , and the top of the second heat conducting block  12  is a plane  121  for attaching and contacting the heat dissipating plate  21 , such that the heat absorbed by the first heat conducting block  11  can be conducted to the heat dissipating plate  21 . 
     In addition, the base  10  further includes a resilient plate  103  bent towards the resilient plate  103  and abutted at a lateral side of the second heat conducting block  12 . The first and second oblique planes  110 ,  120  are inclined in the same direction and disposed on a sidewall  100  of the base  10  for providing a lateral pushing force to the second heat conducting block  12 , so that the second heat conducting block  12  will not slide down along the first oblique plane  110 , and can produce a pushing force upward. 
     With the foregoing structure, the heat conducting apparatus in accordance with the present invention is formed. 
     With reference to  FIG. 2  again, if the heat dissipating plate  21  presses at the plane  121  of the second heat conducting block  12 , two oblique planes  110 ,  120  between the first and second heat conducting blocks  11 ,  12  are slid to adjust the interval between the heat dissipating plate  21  and the heat generating component  200 , such that the plane  111  of the first heat conducting block  11  and the plane  121  of the second heat conducting block  12  are in contact with the heat dissipating plate  21  and the heat generating component  200  respectively for conducting the heat produced by the heat generating component  200  to the heat dissipating plate  21 . Since the first and second heat conducting blocks  11 ,  12  are kept in a close contact with each other by adjusting the two oblique planes  110 ,  120 , a good heat conducting effecting can be maintained among the heat dissipating plate  21 , the heat conducting apparatus  1  and the heat generating component  200 . In addition, the second heat conducting block  12  presses onto the first heat conducting block  11 , so that when the first heat conducting block  11  is in contact with a plurality of heat generating components  200 , the contact between the two oblique planes  110 ,  120  of the first and second heat conducting blocks  11 ,  12  and the limit effect on the periphery of the first heat conducting block  11  provided by the base  10  can reduce the tolerance or gap existed between the first heat conducting block  11  and each heat generating component  200  to keep the first heat conducting block  11  in a close contact with each heat generating component  200 . 
     In summation of the description above, the present invention improves over the prior art and complies with the patent application requirements and thus is duly filed for patent application.
