     Description of Related Art 
     As the computing speed of electronic components increases continuously, the generated heat is getting higher and higher. In order to effectively solve the problem of high heat, heat pipes or vapor chambers with high conductivity and good heat dissipation efficiency are developed in the industries, and some companies are designing and researching water cooling heat dissipation devices. 
     A related-art water cooling heat dissipation device mainly includes a water cooling head, a water pump, a water tank, a water-cooling radiator, and a plurality of water pipes. The water cooling head, the water pump and the water-cooling radiator are all connected through water pipes and joints. 
     Although the related-art water cooling heat dissipation device has a high efficiency of heat dissipation, it has the following problems in use. Since each of the components of the water-cooling heat dissipation device is connected through water pipes and joints, water leakage problems easily occur at each connection position, and cause the surrounding electronic components to be damaged due to moisture. Additionally, the water-cooling heat dissipation device configured by the aforementioned components is bulky, thus the limited internal space in a computer case may be overly occupied, and the processes of installation and maintenance are complicated and difficult. 
     In view of the above drawbacks, the inventor proposes this disclosure based on his expert knowledge and elaborate researches in order to solve the problems of related art.

Thus, the problem of water leakage may be effectively solved. 
     In order to achieve the object mentioned above, this disclosure provides an internal circulation water cooling heat dissipation device including a water cooling head, a delivering structure, a water-cooling radiator, and a water pump. The water-cooling head includes a chamber. The delivering structure is disposed on the water-cooling head and includes a water delivery column.
