Creation Instructions (l) [Technical Field to which the New Type belongs This creation relates to a liquid-cooled heat-dissipating device for heat-dissipating equipment, but electronic components.彳 Inch is related to a kind of cold [previous technology] With the continuous development of electronic technology, electronics_ is constantly improving. However, high frequency and high speed will increase the operating frequency and speed of electrical components. The temperature is also getting higher and higher. The heat generated by the threatening parts is becoming more and more stable and stable. In order to ensure that the electronic components can operate properly when 70 pieces are running, heat is effectively dissipated. 'Standard, existing air-cooled type =: It is necessary to dissipate the electronic components to meet the high-frequency and high-frequency heat dissipation requirements of electronic components, which is difficult to be gradually adopted by the industry. For related technologies, please refer to; number. Continental Patent No. 98284834. 3 With reference to the above patents, it is not difficult to see that the existing liquid human < ^ ... ~ type heat dissipation systems are all connected by a queue / knife installation element, which generally includes a suction unit, a loose soap and a Pump body for cooling liquid. Among these components, the pump body needs to be driven by electricity. For portable computers, laptops, etc. that demand mobile performance, 'It mainly relies on batteries to provide power. If a part of the battery's power is distributed to the pump body, the battery life will be drastically reduced. The portable computer's mobile performance is inferior [Content] _ ° The purpose of this creation is to provide a liquid-cooled heat sink that does not require the use of a pump to drive the cooling fluid, thereby reducing power consumption. π This creative liquid-cooled heat dissipation device 'includes—Evaporation early 70 close to the heating element, a cooling unit standing directly above the evaporation unit, and communication with the steam M252978 5. Creation instructions (2) The hair unit and the cooling The first and second ducts of the unit, the evaporation unit is provided with a cavity for storing working fluid, the cooling unit includes a cooling chamber, and the second duct is installed with a control fluid that can only be removed from the cooling chamber in the second duct. The one-way valve flowing to the cavity, when the working liquid in the evaporation unit absorbs heat and evaporates, the vapor squeezes the high-temperature working liquid back to the cooling chamber along the first duct, and after the working liquid is cooled in the cooling chamber, it flows back to the second duct. Evaporation unit. Since the working liquid circulation of the liquid-cooled heat sink of this creation is driven by the vapor squeeze formed after the working liquid evaporates, there is no need to use a pump body that requires power to drive, thereby saving electricity and reducing material and installation costs. The following describes the creation of step i with reference to the drawings and embodiments. Referring to the first figure, the first embodiment of the liquid-cooled heat dissipation device of the present invention includes an evaporation unit 1, a cooling unit 2, and a first pipe 3 and a second pipe 4 connecting the evaporation unit 1 and the cooling unit 2. The evaporation unit 1 is closely attached to the heating element 100, and is used to absorb the heat of the heating element 100. The evaporation unit 1 has a closed chamber therein, and a working liquid is stored in the chamber. The working liquid uses the characteristics of heating and evaporation to take away the heat of the heating element 100. According to the heating of the heating element, the boiling point of the working liquid is generally about 40 r to 60 ° C, such as acetone, and its boiling point is about 5 6 ° C. The cooling unit 2 is located directly above the evaporation unit 1, and its bottom is closely attached to the top of the evaporation unit 1. The cooling unit 2 includes a cooling chamber 20 and equipment for cooling the cooling chamber 20 placed on the cooling chamber 20, which is used in this embodiment.
M252978 五、創作說明（3) 一散熱器2 6及一散熱風扇2 8。該冷卻室2 0内設有一中空 部，用於容設工作液體。當高溫之工作液體進入該冷卻室 2 0時，散熱器2 6及散熱風扇2 8可對其進行冷卻降溫。 第一導管3連接蒸發單元1之一端插入工作液體中。第 二導管4在與該蒸發單元1鄰近之位置安裝一單向閥5，使 在第二導管4中之工作液體只能由冷卻室2 0向蒸發單元1流 動，而不能由蒸發單元1向冷卻室2 0流動。 本創作液冷式散熱裝置工作過程如下： 當發熱元件1 0 0發熱時，蒸發單元1中之工作液體吸收 發熱元件0之熱量，當被加熱到其沸點時，工作液體蒸 發形成蒸氣填充於該蒸發單元1之頂部，隨著蒸氣之不斷 形成，蒸氣之氣壓會將高溫之工作液體壓又第一導管3中 ，並沿著該第一導管3進入該冷卻室2 0。由於單向閥5可防 · 止蒸發單元1中之工作液體流入第二導管4，因此，被擠壓 ， 之工作液體只能進入第一導管3。 高溫之工作液體進入冷卻室2 0後，在散熱器2 6及散熱 風扇2 8之幫助下降溫冷卻，然後自第二導管4流回至蒸發 單元1進入下一冷卻循環，如此不斷循環，可源源不斷地 帶走發熱元件.1 0 0之熱量。在工作液體沿第二導管4流回蒸 發單元1之過程中，可以是受到單一重力之作用（因為冷 ψ 卻室20高於蒸發單元1)，另一方面可在該第二導管4内壁 設置毛細結構，如此可通過毛細結構之吸附作用加速工作 液體之回流過程。 請參閱第二圖，本創作液冷式散熱裝置第二實施例與M252978 V. Creative Instructions (3) A radiator 26 and a cooling fan 28. A hollow portion is provided in the cooling chamber 20 for containing a working fluid. When the high-temperature working liquid enters the cooling chamber 20, the radiator 26 and the cooling fan 28 can cool and cool it. The first pipe 3 is connected to one end of the evaporation unit 1 and inserted into the working liquid. The second duct 4 is provided with a check valve 5 at a position adjacent to the evaporation unit 1, so that the working liquid in the second duct 4 can only flow from the cooling chamber 20 to the evaporation unit 1, but not from the evaporation unit 1. Cooling chamber 20 flows. The working process of the liquid-cooled heat sink of this creation is as follows: When the heating element 100 generates heat, the working liquid in the evaporation unit 1 absorbs the heat of the heating element 0. When it is heated to its boiling point, the working liquid evaporates to form a vapor to fill the At the top of the evaporation unit 1, as the steam is continuously formed, the pressure of the steam will press the high-temperature working liquid back into the first duct 3 and enter the cooling chamber 20 along the first duct 3. Since the check valve 5 can prevent the working fluid in the evaporation unit 1 from flowing into the second conduit 4, the working fluid that is squeezed can only enter the first conduit 3. After the high-temperature working liquid enters the cooling chamber 20, it is cooled down with the help of the radiator 26 and the cooling fan 28, and then flows back from the second duct 4 to the evaporation unit 1 to enter the next cooling cycle. Continuously take away the heat from the heating element. 1 0 0. In the process of the working fluid flowing back to the evaporation unit 1 along the second duct 4, it may be subjected to a single gravity (because the cold ψ cooling chamber 20 is higher than the evaporation unit 1). On the other hand, it can be provided on the inner wall of the second duct 4. Capillary structure, which can speed up the backflow process of working fluid through the adsorption of capillary structure. Please refer to the second figure, the second embodiment of the liquid-cooled heat sink of this creation and
