Description

散热鳍片组Fin set

技术领域technical field

本发明涉及一种散热鳍片组,尤其是涉及一种具空心散热柱的散热鳍片组。The invention relates to a cooling fin group, in particular to a cooling fin group with a hollow cooling column.

背景技术Background technique

随着电子科技的发展,电子元件的效能相对提高。伴随而来的是电子元件在单位时间内所发出的热量越来越多。因此,为了避免电子元件温度过高而导致电子元件的效能降低或当机,常见的散热方式为加装一散热器于电子元件上方。如此一来,可借助散热器将电子元件发出的热量散出,进而降低电子元件的温度。With the development of electronic technology, the efficiency of electronic components has been relatively improved. Accompanying it is that electronic components emit more and more heat per unit time. Therefore, in order to prevent the performance of the electronic components from being reduced or crashed due to overheating of the electronic components, a common cooling method is to install a heat sink above the electronic components. In this way, the heat emitted by the electronic components can be dissipated by means of the heat sink, thereby reducing the temperature of the electronic components.

传统的散热器主要分为主动式散热与被动式散热。主动式散热一般包括风扇与散热鳍片。散热鳍片贴附于电子元件上,使电子元件发出的热量能够传导至散热鳍片。当风扇运转时,风扇引导气流吹向散热鳍片,以将传导至散热鳍片的热量带走,进而达到散热的效果。被动式散热一般仅借助散热鳍片贴附于电子元件上,并通过自然对流的方式将传导至散热鳍片的热量带走。然而,因为传统散热器采用实心的散热鳍片,仅散热鳍片的外部单一散热途径能够进行散热,故传统散热器应用于高发热量的电子元件时,其散热效能恐跟不上高发热量的电子元件的热量产生速度。Traditional radiators are mainly divided into active cooling and passive cooling. Active cooling generally includes fans and cooling fins. The cooling fins are attached to the electronic components, so that the heat emitted by the electronic components can be conducted to the cooling fins. When the fan is running, the fan guides the airflow to blow to the heat dissipation fins, so as to take away the heat conducted to the heat dissipation fins, thereby achieving the effect of heat dissipation. Passive heat dissipation is generally attached to electronic components only by means of heat dissipation fins, and the heat conducted to the heat dissipation fins is taken away by natural convection. However, because traditional heat sinks use solid heat dissipation fins, only a single heat dissipation path outside the heat dissipation fins can dissipate heat. Therefore, when traditional heat sinks are applied to electronic components with high calorific value, their heat dissipation performance may not be able to keep up with electronic components with high calorific value. The rate at which heat is generated by the component.

图1为本发明实施例一散热鳍片组的立体示意图。请参阅图1,本实施例散热鳍片组10a包括一基部100与多个空心散热柱200。其中基部100具有一第一表面101、一第二表面102及多个组装孔110。第二表面102相对于第一表面101。组装孔110自第一表面101延伸至第二表面102。空心散热柱200分别嵌设于基部100的组装孔110。每一空心散热柱200具有一散热通道210。散热通道210分别连通组装孔110。每一空心散热柱200具有一第一端201与相对的第二端202,两者分别对应有一第一端面203与一第二端面204。在本实施例中,空心散热柱200的第一端201凸出于基部100的第一表面101。空心散热柱200的第二端面204与基部100的第二表面102切齐。FIG. 1 is a three-dimensional schematic diagram of a heat dissipation fin set according to an embodiment of the present invention. Please refer to FIG. 1 , the heat dissipation fin set 10 a of the present embodiment includes a base 100 and a plurality of hollow heat dissipation columns 200 . The base 100 has a first surface 101 , a second surface 102 and a plurality of assembly holes 110 . The second surface 102 is opposite to the first surface 101 . The assembly hole 110 extends from the first surface 101 to the second surface 102 . The hollow cooling posts 200 are respectively embedded in the assembly holes 110 of the base 100 . Each hollow cooling column 200 has a cooling channel 210 . The heat dissipation channels 210 communicate with the assembly holes 110 respectively. Each hollow cooling column 200 has a first end 201 and an opposite second end 202 , which respectively correspond to a first end surface 203 and a second end surface 204 . In this embodiment, the first end 201 of the hollow cooling post 200 protrudes from the first surface 101 of the base 100 . The second end surface 204 of the hollow cooling post 200 is flush with the second surface 102 of the base 100 .

此实施例中,电子元件20的热量可经由热管导送至本散热鳍片组10a进行散热,也可将发热的电子元件20直接贴附于本散热鳍片组10a进行散热。下面以电子元件20直接贴附于本散热鳍片组10a为例,图2a为图1散热鳍片组与电子元件贴附方式的剖面示意图,图2b为图1散热鳍片组与电子元件另一贴附方式的剖面示意图,请参阅图2a与图2b。如图2a所述,散热鳍片组10a可通过基部100的第二表面102与发热电子元件20热接触。如图2b所述,散热鳍片组10a通过空心散热柱200的第一端面203与发热电子元件20热接触。In this embodiment, the heat of the electronic component 20 can be conducted to the heat dissipation fin set 10a via the heat pipe for heat dissipation, or the heat-generating electronic component 20 can be directly attached to the heat dissipation fin set 10a for heat dissipation. Taking the electronic component 20 directly attached to the cooling fin group 10a as an example, FIG. 2a is a schematic cross-sectional view of the attachment method of the cooling fin group and the electronic component in FIG. 1, and FIG. Please refer to FIG. 2a and FIG. 2b for a schematic cross-sectional view of an attachment method. As shown in FIG. 2 a , the heat dissipation fin set 10 a can be in thermal contact with the heat generating electronic component 20 through the second surface 102 of the base 100 . As shown in FIG. 2 b , the heat dissipation fin set 10 a is in thermal contact with the heat generating electronic component 20 through the first end surface 203 of the hollow heat dissipation column 200 .

另外,此实施例中,由于空心散热柱200的散热通道210与基部100的组装孔110连通,因此除空心散热柱200外部空间可供热气流通外,气流还可流经空心散热柱200内部的散热通道210,通过双重散热途径的散热气流将传导至空心散热柱200的热量排出,达到提升散热鳍片组10a散热速率的技术效果。In addition, in this embodiment, since the heat dissipation channel 210 of the hollow heat dissipation column 200 communicates with the assembly hole 110 of the base 100, in addition to the space outside the hollow heat dissipation column 200 for the circulation of hot air, the airflow can also flow through the interior of the hollow heat dissipation column 200. The heat dissipation channel 210 of the heat dissipation channel 210 discharges the heat conducted to the hollow heat dissipation column 200 through the heat dissipation air flow of the double heat dissipation path, so as to achieve the technical effect of increasing the heat dissipation rate of the heat dissipation fin set 10a.

图3为利用图1散热鳍片组搭配风扇对电子元件进行散热而测得的电子元件的温度时间曲线示意图;下表一为利用图1的散热鳍片组搭配风扇对电子元件进行散热而测得的电子元件温度随时间变化的纪录表。请参阅图3与表一,根据图3与表一所述,传统的散热鳍片组的基部并未嵌设空心散热柱,即如表一的空心散热柱数量为零个的状态。当传统的散热鳍片组搭配风扇对温度为80摄氏度的电子元件20进行散热时,电子元件20的温度在风扇开启24分钟后自80摄氏度降至62摄氏度。Figure 3 is a schematic diagram of the temperature-time curve of the electronic component measured by using the heat dissipation fin set in Figure 1 with a fan to dissipate heat from the electronic component; the following table 1 is the measurement of the heat dissipation of the electronic component by using the heat dissipation fin set in Figure 1 with a fan The record table of the obtained electronic component temperature change with time. Please refer to FIG. 3 and Table 1. According to FIG. 3 and Table 1, the base of the conventional cooling fin set does not have hollow heat dissipation columns embedded, that is, the number of hollow heat dissipation columns in Table 1 is zero. When the traditional cooling fin set is used with a fan to dissipate heat from the electronic component 20 at a temperature of 80 degrees Celsius, the temperature of the electronic component 20 drops from 80 degrees Celsius to 62 degrees Celsius 24 minutes after the fan is turned on.

此外,在表一中,分别将散热鳍片组10a分成空心散热柱200数量为33、57、81根三种状况。当空心散热柱200数量为33根的散热鳍片组10a搭配风扇对温度为80摄氏度的电子元件20进行散热时,电子元件20的温度在风扇开启24分钟后自80摄氏度降至56摄氏度。与基部100未嵌设空心散热柱200相比,基部100嵌设33根空心散热柱200时,电子元件20的温度多降低了6摄氏度。In addition, in Table 1, the heat dissipation fin group 10a is divided into three situations where the number of hollow heat dissipation columns 200 is 33, 57, and 81. When the hollow cooling column 200 with 33 cooling fins 10a is used with the fan to dissipate heat from the electronic component 20 at a temperature of 80 degrees Celsius, the temperature of the electronic component 20 drops from 80 degrees Celsius to 56 degrees Celsius 24 minutes after the fan is turned on. Compared with the base 100 not embedded with the hollow heat dissipation pillars 200 , when the base 100 is embedded with 33 hollow heat dissipation pillars 200 , the temperature of the electronic component 20 is reduced by 6 degrees Celsius more.

而当空心散热柱200数量为57的散热鳍片组10a对温度为80摄氏度的电子元件20进行散热时,电子元件20的温度在风扇开启24分钟后自80摄氏度降至51摄氏度,与基部100未嵌设空心散热柱200相比,基部100嵌设57根空心散热柱200时,电子元件20的温度多降低了11摄氏度。And when the number of hollow cooling columns 200 is 57 and the cooling fin group 10a is cooling the electronic component 20 with a temperature of 80 degrees Celsius, the temperature of the electronic component 20 drops from 80 degrees Celsius to 51 degrees Celsius after the fan is turned on for 24 minutes. Compared with no hollow heat dissipation pillars 200 embedded, when the base 100 is embedded with 57 hollow heat dissipation pillars 200 , the temperature of the electronic component 20 is lowered by 11 degrees Celsius more.

而当空心散热柱200数量为81的散热鳍片组10a对温度为80摄氏度的电子元件20进行散热时,电子元件20的温度在风扇开启24分钟后自80摄氏度降至49摄氏度,与基部100未嵌设空心散热柱200相比,基部100嵌设81根空心散热柱200时,电子元件20的温度多降低了13摄氏度。And when the number of hollow cooling columns 200 is 81 and the cooling fin group 10a is radiating heat to the electronic component 20 with a temperature of 80 degrees Celsius, the temperature of the electronic component 20 drops from 80 degrees Celsius to 49 degrees Celsius after the fan is turned on for 24 minutes. Compared with no hollow heat dissipation pillars 200 embedded, when the base 100 is embedded with 81 hollow heat dissipation pillars 200 , the temperature of the electronic component 20 is reduced by 13 degrees Celsius more.

一般而言,当温度介于45摄氏度至55摄氏度时,电子元件20的运作效能最佳。而根据散热测试结果可知散热鳍片组10a基部100嵌设空心散热柱200后进行散热,电子元件20的降温速度变快,且可使电子元件20的温度较快降温至接近或是落于工作效能较佳的温度区间。Generally speaking, when the temperature is between 45 degrees Celsius and 55 degrees Celsius, the performance of the electronic device 20 is the best. According to the heat dissipation test results, it can be seen that the base 100 of the heat dissipation fin group 10a is embedded with the hollow heat dissipation column 200 to dissipate heat, the cooling speed of the electronic component 20 becomes faster, and the temperature of the electronic component 20 can be quickly cooled to close to or fall below the working temperature. The temperature range with better performance.

In order to enhance heat conduction, the heat dissipation fin set 10 can be composed of a composite material of a hollow heat dissipation column 200 with a relatively high thermal conductivity and a base portion 100 with a relatively low thermal conductivity. For example: the hollow heat dissipation column 200 is made of metal copper and the base 100 is made of metal aluminum.

根据上述实施例的散热鳍片组,由于本发明采用空心散热柱取代传统常见的实心散热鳍片,且将空心散热柱分别嵌设于基部的组装孔。空心散热柱的散热通道以及侧连接道连通基部的组装孔。因此除散热面积增加外,本发明的散热鳍片组除空心散热柱外部空间可供热气流通外,另气流还可流经空心散热柱内部的散热通道。使散热气流可经由双重散热途径将传导至空心散热柱的热量排出。此外,本发明的散热鳍片组与热源接触的表面可以是凸出空心散热柱的一端面或是基部的任一表面。再者,本发明可借助空心散热柱与基部的相异材质组成加强热传导增强散热效果。According to the heat dissipation fin set of the above embodiment, the present invention uses hollow heat dissipation columns instead of conventional solid heat dissipation fins, and the hollow heat dissipation columns are respectively embedded in the assembly holes of the base. The heat dissipation channel of the hollow heat dissipation column and the side connection channel communicate with the assembly hole of the base. Therefore, in addition to increasing the heat dissipation area, the heat dissipation fin assembly of the present invention not only allows hot air to circulate in the space outside the hollow heat dissipation column, but also allows air to flow through the heat dissipation channel inside the hollow heat dissipation column. The heat dissipation airflow can discharge the heat conducted to the hollow heat dissipation column through double heat dissipation paths. In addition, the surface of the heat dissipation fin group of the present invention in contact with the heat source may be an end surface of the protruding hollow heat dissipation column or any surface of the base. Furthermore, the present invention can enhance heat conduction and heat dissipation effect by virtue of different material compositions of the hollow heat dissipation column and the base.
