Description

200401867 V. Description of the invention (1) "Technical field to which the invention belongs". The present invention relates to a "combined diversion fan", which is formed by the first diversion fan and the second diversion fan. A deflector is provided on the air outlet side of the first deflector fan, a deflector is provided on the air inlet side of the second deflector fan, and an air outlet group of the first diversion fan is provided on the second diversion fan. The air outlet makes the guide parts of the first diversion fan and the second diversion fan to be in close contact with each other to form a diversion air duct, thereby increasing the wind pressure and air flow of the air flow. "Previous Technology" With the rapid development of electronic components, their volume is reduced, and the computing speed is increased by __. However, if the heat dissipation problems that come with it cannot be effectively ruled out, it will often cause the electronic components to operate smoothly or even be damaged. ^ When using a cooling fan as a way to remove the heat of electronic components, there is a diversion fan with a deflector on the cooling fan to control the output wind direction of the cooling fan to achieve the effect of concentrated airflow, but the diversion The fan still has the disadvantage of insufficient air volume; please refer to the first to third figures. If the above-mentioned diversion fans are arranged as follows, they mainly include a first diversion fan 11 and a second diversion fan. 1 2. The first deflector fan 1 1 has a radiating blade 1 1 1 and a deflector 1 1 2. The deflector 1 1 2 is composed of a plurality of deflector blades 1 1 2 a, and the deflector The air flow section 1 1 2 is provided on the air outlet 1 1 3 < 1 side of the first air flow guide fan 1 1. The second air flow guide fan 12 has a heat radiation blade 1 2 1 and a air flow guide section 1 2 2. The deflector 1 2 2 is composed of a plurality of deflector blades 1 2 2 a, and the deflector 1 2 2 is provided on the air inlet 1 2 3 side of the second deflector fan 12; the first deflector fan 1 1 air outlets 11 3 sets of air inlets 1 2 3 of the second diversion fan 1 2 but

200401867 V. Description of the invention (2) Because the guide vanes 1 1 2 a and 1 2 2 a are interlaced and fitted together, the overall wind flow is disordered, which reduces the wind pressure and air flow of the combined output air flow, so This method of using two diversion fans to set up each other does not achieve the purpose of increasing the output air flow, wind pressure and air flow. Furthermore, in the "radiator structure with multi-layered fan blades" of the Republic of China Patent Publication No. 4 9 0 1 31, "it has an outer casing" and a receiving groove is provided in the outer casing, and the receiving groove is provided in the receiving groove. The base is characterized in that: a plurality of fan blades are arranged in the outer shell, and the plurality of fan blades include a static wing group and a structure assembled on the upper side, the lower side of the static wing group and the moving wing group; it uses a plurality of moving wing groups to induce a large number of The airflow can achieve better heat dissipation effect, but if one of the moving wing groups is damaged, the whole heat sink group must be replaced to achieve the original heat dissipation effect, which will increase the cost and reduce the cost. Computer performance. The reason is that, in view of the various shortcomings derived from the above-mentioned custom goods, the inventor of this case tried his best to improve the case by perfecting it, and engaged in many years of experience in the industry. This "Combined Diversion Fan" case is actually an invention with improved efficacy. "Objective of the Invention" The main purpose of the present invention is to provide a combined diversion fan that effectively improves the wind pressure and air flow of the wind flow; the invention A secondary objective is to provide a combined diversion fan that can quickly replace the diversion fan therein. Another object of the present invention is to provide a combination of

The diversion part 2 1 2 is composed of a plurality of diversion blades. 2 1 2 a 'and the deflector 2 1 2 is provided on the air outlet 2 1 3 side of the first deflector fan 2 1; wherein the second deflector fan 2 2 has a heat dissipation blade 2 2 1 and a deflector The deflector 2 2 2 is composed of a plurality of deflector blades 2 2 2 a and the deflector 2 2 2 is provided at the air inlet 2 2 of the second deflector fan 2 2 3 sides.

The younger " air outlet 2 1 3 of the deflector fan 2 1 is set at the air inlet 2 2 3 of the younger deflector fan 2 2 and the deflector 2 1 2 of the first deflector fan 2 1 and The diversion blades 2 1 2 a and the diversion tea pieces 2 2 2 a on the diversion part 2 2 2 of the second diversion fan 2 2 are in close contact with each other to form a diversion air duct 23. The diversion air duct 2 3 series enables the wind current generated by the first diversion fan 2 1 to be blown to the center of the second diversion fan 2 2 centrally or according to the demand of heat dissipation so that the air current is blown to the heat dissipation blades 2 2 of the 2 diversion fan 2 2 1 Outside; when the heat dissipation blades 2 1 1 of the first diversion fan 2 1 are powered on, it can increase the wind pressure of the air flow to the second diversion fan 2 2, and the wind current generated by the first diversion fan 21 1 Via the first deflector fan 2 1

200401867 V. Description of the invention (4) The guide vanes 2 1 2 a and the guide vanes 2 2 2 a on the guide unit 2 1 2 and the second guide fan 2 2 2 2 2 The diversion air duct 2 3 ′ can concentrate the air flow and increase the wind pressure to blow against the second diversion fan 2 2; increase the wind pressure through the first diversion fan 21 and the concentrated air flow and increase the diversion air duct 23. Pressure, and then run and blow through the heat dissipation blades 2 2 1 of the second diversion fan 2 2 to increase the wind pressure and air flow of the combined output wind current of the combined diversion fan. In addition, the present invention is composed of the first diversion fan 21 and the second diversion fan 22. When one of the diversion fans is damaged, it can be quickly replaced and used to reduce the damage of the conventional diversion fan. In this case, the disadvantages of the whole group replacement are needed, Trent is easy to use and reduces costs. In addition, in the electronic component that needs to increase the heat dissipation effect and fast heat dissipation, the first diversion fan 21 and the second diversion fan 22 can be arranged in pairs with each other to form a plurality of series of diversion fans. Set up method to increase the overall air flow and wind pressure blown to the electronic components. Please refer to the eighth to tenth drawings, which are the second embodiment of the present invention. As shown in the figure, they are formed by the first diversion fan 31 and the second diversion fan 3 2. The first deflector fan 3 1 has a radiating blade 3 1 1 and a deflector 3 1 2 ′. The deflector 3 1 2 is composed of a plurality of deflectors 3 1 2 a, and the deflector 3 1 2 is provided on the side of the air outlet 3 1 3 of the first diversion fan 3 1 and protrudes from the first diversion fan 3 1; wherein the second diversion fan 3 2 has a radiating blade 3 2 1 and a diversion The guide portion 3 2 2 is composed of a plurality of guide blades 3 2 2 a, and the guide portion 3 2 2 is provided at the air inlet 3 2 3 of the second guide fan 3 2 The second deflection fan 3 2 is projected laterally, and the heat dissipation blades 3 1 2 a and 3 2 2 a are designed to be staggered in order.

200401867 V. Description of the invention (5) Set the air outlets 3 1 3 of the first diversion fan 3 1 to the air inlets 3 2 3 of the second diversion wind-fan 3 2 due to the guide vanes 3 1 2 a And the deflector blades 3 2 2 a are designed in a staggered arrangement in sequence, and because the radiating blades 3 1 2 a and 3 2 2 a protrude from the first diversion fan 3 1 and the second diversion 3 2, During assembly, the radiating blades 31 2a are protruded into the second guide fan 32, and the radiating blades 3 2 2a are protruded into the first guide fan 3 1 so that the guide vanes 3 1 2 a and the guide vane 3 2 2 a A diversion air duct 3 3 is formed between the first diversion fan 31 and the second diversion fan 3 2. Therefore, after the assembly of this embodiment is completed, the wind pressure for increasing the overall output airflow of the first embodiment can be achieved. And air flow, and when one of the deflector fans is damaged, it can be quickly replaced to reduce the disadvantages of the conventional group of fans when the deflector fans are damaged.
