[Technical field to which the invention belongs]

 The present invention relates to a cooling liquid circulation pump type heat absorbing device, in particular, a heat absorbing device which achieves an excellent heat absorbing effect based on the convection characteristics of a liquid and a gas by combining a cooling liquid stored in a housing with a radiating fin used both inside and outside. It is about.

[Prior art]

 It can be said that today is more than 2,000 years, and it is a time of rapid progress in science and technology. For example, living events, work affairs, and leisure have all introduced management of science and technology. In particular, the influence of the central processing unit (CPU) included in the computer is already seeping into the life of an individual.

[0003] With the rapid upgrade of the computer industry, computers have been equipped with brotherly computing power, and the processing speed of central processing units has been increasing one after another, but the heat energy generated by them has nevertheless been increasing. As a result, many types of heat radiating devices have been proposed that can increase the heat radiating area in order to operate the central processing unit normally at the permitted temperature. It has become.

[0004] However, in the case of a heating means for processing thermal energy used in the central processing unit at hand, the processing speed cannot be effectively used at present because the processing speed is continuously increased, and such a heating means cannot be used. The heat dissipation function of the conventional heat dissipation device should be further improved.

As shown in FIG. 1, in a conventional desktop type computer, all the heat radiating devices of the central processing unit 10a adopt means such as open upright type radiating fins 11a, and the central processing unit of the computer main body. The heat energy generated by 10a is dissipated from the bottom portion 12a to the radiating fins 11a, and the heat is radiated by using the fan 13a together.

Further, as shown in FIG. 2, heat radiation fins 20a having a circumferential distribution are centered on a central cylindrical heat conductor 21a, and heat energy is radiated to the surroundings by using a fan 22a together. Some may provide an overall heat dissipation function.

However, in the case of the conventional heat radiation fins described above, the heat radiation efficiency is such that the portion of the heat radiation fin facing the fan is a sealing plane, and the heat radiation ability in a limited space is concentrated. In particular, in the case of the conventional open-type radiating fins, the heat energy to be discharged is transmitted by the heat-conducting method because the open-type radiating fins are solid substances. Since the speed is much lower than the heat energy generated during the operation of the central processing unit by the heat convection circulation, the heat radiation efficiency is not favorable.

Further, when examining the true practicality of the above-mentioned conventional heat radiating means for a computer main body, it is possible to discover that there are obviously many defects, and there is a problem of the above-mentioned widespread practical use. In addition, there is an issue that cannot be achieved in extending the life of the main body.
