Description

M255639 Creative Instructions (1) The technical field to which the new type belongs, especially one related to the new type, is that ^ ^ will be used to dissipate the γ-ray source of the ray 枇 turtle turtle i to provide heat dissipation, and the power supply will benefit the hot gas exhaust flow [previous technology]] The design of the fan = a power supply such as the Republic of China Patent Bulletin No. 5 593 〇: Do not apply to the heat sink of the power output power supply device. The technical characteristics of the former two benefits are mainly used in electronic circuits to reduce Electronic heating elements such as voltage rectifiers, the positioning device is located on the inner surface of the heat conduction plate, and the outer side of the heat conduction plate is tightly connected to the side wall of the power supply, and the front end of the power supply is provided with a wind drum, so that the wind drum can draw outside heat. When the cold air directly blows the heat-conducting plate and the electronic heating element, and a cover is fixedly fixed on the heat-conducting plate, a power supply can be connected to the power supply, and the power can be supplied to the computer through step-down rectification. The electronic heating element will quickly transfer the heat generated by it to the 'hot plate', and will be guided and dissipated by the side wall and the cover, and the wind drum fixed at the front end will simultaneously draw Cold air into the outside, and a strong air stream 'to direct cool the thermally conductive plate and the electronic heat-generating element, a mesh multiplexed escape outwardly of the rear end, so as to achieve optimum cooling and heat dissipation effect. In fact, the front-opening patent is not effective in actual heat dissipation, and the reasons are listed as follows: (1) Because the front-opening patent places the wind drum in the airflow inflow end of the power supply (that is, the rear end of the power supply), the electronic heats up. The output of the wheel of the component will not be able to adopt the golden finger design, but it is necessary to open an additional outlet hole for the power supply and use the power cable to make the output end. Therefore, the case cannot support the redundant power supply design. Computer equipment needs today

M255639 Fourth, the creation description (2) is not effective. (2) Because the air suction part of the wind drum is longitudinally sucking relative to the power supply, if there is no partition between the wind drum and the electronic heating element, the air drum will draw the air in addition to the external cold air when it draws air. Together with the high-temperature airflow that has passed through the electronic heating element, it will also be sucked back by the backflow and cause the hot gas to return. This will increase the temperature of the airflow that is actually blown to the electronic heating element. It is not entirely drawn from the external cold airflow, which will actually cool down the heat. The effect is even lower. (3) The patent must be designed with an additional heat conduction plate to increase product costs, and the configuration of electronic heating components has a large value = production, organization requirements, and the use of \] value is too low. : The serious defects are all important lessons that the new model wants to solve. Therefore, in order to improve the aforementioned defects, the creator has applied continuously.
