Abstract
Description
本發明是有關於一種散熱模組與可攜式電子裝置。The invention relates to a cooling module and a portable electronic device.
隨著電子領域之技術不斷演進,所生產出之電子元件的效能也不斷提升。然而,一般來說電子元件的效能提升,其所產生的熱量就會增加。這些熱量不斷累積於電子元件上而導致電子元件本身的溫度升高。若無法有效將熱量自電子元件排除,讓電子元件的溫度下降,則將會使電子元件發生當機,甚或燒毀。因此,現在電子業普遍上會面臨到的問題不是效能上的提升,而是如何有效地排除熱量。With the continuous evolution of technology in the electronic field, the performance of the produced electronic components is also continuously improved. However, generally speaking, as the performance of electronic components improves, the heat generated by them will increase. The heat continuously accumulates on the electronic components and causes the temperature of the electronic components to rise. If the heat cannot be effectively removed from the electronic components to lower the temperature of the electronic components, the electronic components will crash or even be burned. Therefore, the problem generally faced by the electronics industry is not to improve performance, but how to effectively remove heat.
一般來說,業界係透過氣冷式散熱裝置來達到熱量的排除,氣冷式散熱裝置一般包含風扇、散熱鰭片及熱管。散熱鰭片位於風扇之出風口,且熱管連接熱源及散熱鰭片以將熱源之熱量傳導至散熱鰭片。當風扇運轉時可形成氣流流過散熱鰭片,以令氣流與散熱鰭片進行熱交換而將散熱鰭片上之熱量排掉。Generally speaking, the industry uses an air-cooled heat dissipation device to achieve heat removal. The air-cooled heat dissipation device generally includes a fan, heat dissipation fins, and heat pipes. The heat dissipation fins are located at the air outlet of the fan, and the heat pipes are connected to the heat source and the heat dissipation fins to transfer the heat from the heat source to the heat dissipation fins. When the fan is running, an airflow can be formed to flow through the heat dissipation fins, so that the airflow can exchange heat with the heat dissipation fins to dissipate the heat on the heat dissipation fins.
對於筆記型電腦而言,隨著運算效能的提升,為了達到有效散熱,採用具有雙出風口的風扇已逐漸成為常態且必須,但實際上,隨著操作模式的改變,筆記型電腦並非隨時皆需要處於全功率散熱的狀態,然而現有雙出風口的風扇並未對此有進一步的技術手段。For notebook computers, with the improvement of computing performance, in order to achieve effective heat dissipation, it has gradually become normal and necessary to use fans with dual air outlets. It needs to be in a state of full power heat dissipation, but the existing fans with double air outlets do not have further technical means for this.
本發明提供一種散熱模組,以因應可攜式電子裝置的操作模式而調整對應的散熱效能。The invention provides a heat dissipation module for adjusting the corresponding heat dissipation performance in response to the operation mode of the portable electronic device.
本發明的散熱模組,包括風扇、擋板、螺桿套筒以及馬達。風扇具有多個出風口。擋板樞設於風扇且位於其中一出風口,擋板具有延伸出風扇的螺桿。螺桿套筒可移動地耦接於螺桿。馬達連接且驅動螺桿套筒沿螺桿往復移動,以旋轉螺桿而驅動擋板開闔出風口。The heat dissipation module of the present invention includes a fan, a baffle, a screw sleeve and a motor. The fan has multiple air outlets. The baffle is pivotally arranged on the fan and located at one of the air outlets, and the baffle has a screw extending out of the fan. The screw sleeve is movably coupled to the screw. The motor is connected to drive the screw sleeve to move back and forth along the screw, so as to rotate the screw to drive the baffle to open and close the air outlet.
本發明的可攜式電子裝置,包括機體、多個風扇與至少一切換組件。風扇是配置於機體內的離心式風扇,各風扇具有多個出風口,切換組件配置於至少一出風口。切換組件包括擋板、螺桿套筒與馬達。擋板樞設於風扇,擋板具有延伸出風扇的螺桿。螺桿套筒可移動地耦接於螺桿。馬達連接且驅動螺桿套筒沿螺桿往復移動,以旋轉螺桿而驅動擋板開闔出風口。The portable electronic device of the present invention includes a body, a plurality of fans and at least one switching component. The fan is a centrifugal fan arranged in the body, each fan has a plurality of air outlets, and the switching component is arranged at least one of the air outlets. The switching assembly includes a baffle, a screw sleeve and a motor. The baffle is pivotally arranged on the fan, and the baffle has a screw extending out of the fan. The screw sleeve is movably coupled to the screw. The motor is connected to drive the screw sleeve to move back and forth along the screw, so as to rotate the screw to drive the baffle to open and close the air outlet.
基於上述實施例,本發明在可攜式電子裝置的散熱模組中,藉由在風扇的多個出風口的至少其中之一處設置切換組件,以對出風口進行啟閉控制,而據以控制風扇的氣流量來達到散熱效能的調整。詳細來說,散熱模組於風扇的其中一出風口處設置活動擋板,並藉由螺桿、螺桿套筒與馬達的對應配置,而讓使用者能通過馬達驅動擋板開闔風扇的出風口。據此,使用者即能針對可攜式電子裝置的操作模式而對應調整風扇的氣流量,以使風扇能在多個出風口提供均勻的散熱氣流,或是關閉其中一出風口而使氣流集中於剩餘出風口加強該處的氣流量。Based on the above-mentioned embodiments, in the heat dissipation module of the portable electronic device, the present invention sets a switching component at at least one of the multiple air outlets of the fan to control the opening and closing of the air outlet, and according to Control the air flow of the fan to adjust the cooling performance. In detail, the heat dissipation module sets a movable baffle at one of the air outlets of the fan, and through the corresponding configuration of the screw, screw sleeve and motor, the user can drive the baffle to open and close the air outlet of the fan . According to this, the user can adjust the air flow of the fan according to the operation mode of the portable electronic device, so that the fan can provide uniform cooling airflow at multiple air outlets, or close one of the air outlets to concentrate the airflow Increase the air flow at the remaining air outlets.

Please refer to FIG. 1 and FIG. 2 at the same time. In this embodiment, the
圖3是圖2的散熱模組於另一狀態的示意圖。請同時參考圖2與圖3,詳細而言,本實施例的切換組件SW還包括承載件143,其是由承架143a與架設在承架143a上的導桿143b所組成。風扇110具有多個側牆以形成出風口E1、E2,擋板130包括彼此鄰接的板體131與樞軸132,且板體131藉由樞軸132而可旋轉地架設於其中兩個側牆111A、111B之間而使板體131位於其中一出風口(本實施例為出風口E1),前述擋板130的第一螺桿133即是與樞軸132同軸設置而同步旋轉,且本實施例的第一螺桿133實質上也架設在承架143a上並位於導桿143b的一側。FIG. 3 is a schematic diagram of the cooling module in FIG. 2 in another state.

請再參考圖1,本實施例藉由切換組件SW而能順利地控制風扇110的出風口(如圖2、圖3所示出風口E1)的啟閉,也相當於在圖1分別控制散熱氣流F1、F3的存在與否,其能依據可攜式電子裝置10的操作模式而對應改變,而提供對應的散熱效能。本實施例僅作為例示,亦即在其他未繪示的實施例中,設計者可在需要進行啟閉調整得出風口處皆配置切換組件。Please refer to FIG. 1 again.
