Description

一种电子散热器An electronic radiator

技术领域technical field

本发明涉及散热器领域，具体涉及一种电子散热器。The invention relates to the field of radiators, in particular to an electronic radiator.

背景技术Background technique

如今，在计算机产业中，为将微处理芯片等发热电子元件产生的热量有效散发，通常采用的方法是将一散热器紧贴于发热电子元件的溢热表面，以协助发热电子元件散热，保证发热电子元件在适当的温度下运作。Nowadays, in the computer industry, in order to effectively dissipate the heat generated by heat-generating electronic components such as microprocessor chips, the usual method is to attach a heat sink to the surface of the heat-dissipating electronic components to assist the heat-generating electronic components to dissipate heat and ensure Heat-generating electronic components operate at the proper temperature.

现有的散热器一般由若干散热片、热管及基座组成，其中该等散热片上分别设有一穿孔，利用该穿孔将各散热片叠合穿设在该热管的一端，该热管的另一端与该基座连接。该基座贴设在一发热电子元件上，用于吸收发热电子元件产生的热量，并通过该热管将吸收的热量传递到散热片上散发出去。通常，可借助一冷却风扇来对该散热片进行辅助散热。然而，现有的散热片结构一般为平板型，散热面积较小，冷却风扇产生的冷却气流流过时难以形成涡流，导致散热片与该冷却气流间的热交换系数较低，不易高效散发发热电子元件产生的热量。Existing radiators are generally composed of several heat sinks, heat pipes and bases, wherein the heat sinks are respectively provided with a perforation, and each heat sink is stacked on one end of the heat pipe through the perforation, and the other end of the heat pipe is connected to the heat pipe. The base is connected. The base is pasted on a heating electronic component for absorbing the heat generated by the heating electronic component, and transferring the absorbed heat to the cooling fin through the heat pipe for dissipating. Usually, a cooling fan can be used to assist heat dissipation of the heat sink. However, the existing heat sink structure is generally flat, with a small heat dissipation area, and it is difficult to form eddy currents when the cooling airflow generated by the cooling fan flows through, resulting in a low heat exchange coefficient between the heat sink and the cooling airflow, making it difficult to efficiently dissipate heat-generating electrons. heat generated by the component.
